  • Professional audits offer precise insights and can cut energy bills by 5%–30%, often paying for themselves within a year.
  • Government incentives, like a 30% tax credit (up to $150), are available for professional audits through 2025.

Choosing between the two depends on your budget, property size, and energy-saving goals.

What Energy Audits Are and Why You Need Them

Energy Audit Basics

An energy audit is all about evaluating how efficiently your building uses energy and identifying where it’s being wasted. Think of it as a check-up for your property’s energy health, helping you figure out where your money is going when it comes to energy bills.

“An energy audit is an inspection survey and an analysis of energy flows for energy conservation in a building.” – Wikipedia

During an audit, either a professional or a homeowner inspects the property to uncover issues. This could mean noticing air leaks around aging windows, finding gaps in insulation, or realizing that your HVAC system is working overtime.

But it’s not just about identifying problems. Energy audits provide clear, actionable recommendations tailored to your specific building. These could include adding better insulation, upgrading outdated wiring, installing energy-efficient lighting, or replacing an overworked HVAC system.

In many ways, an energy audit is your starting point for making smart energy-saving choices. Instead of guessing where to invest your time and money, an audit gives you a detailed roadmap to maximize the impact of your efforts.

Why Energy Audits Matter

The benefits of energy audits go far beyond just trimming your utility bills – though that alone is a pretty compelling reason. Homeowners who follow through on audit recommendations can cut their energy use by 10% to 30%, which translates to savings of 5% to 30% on monthly energy costs. For businesses, the potential savings can climb as high as 30%.

“A home energy audit helps you identify areas where your home wastes energy, offering valuable tips to improve efficiency, lower bills, and boost comfort.” – Bianca Phillips, GoodLeap

Comfort is another big win. By tackling issues like drafts or uneven temperatures, energy audits can eliminate the frustration of that one room that’s always freezing in winter or sweltering in summer. Plus, they can address ventilation problems that might lead to mold, protecting both your property and your health.

Then there’s the environmental angle. Making energy-efficient changes in commercial buildings can cut greenhouse gas emissions by up to 30%. Every kilowatt-hour saved means a smaller carbon footprint.

“Energy audits are powerful tools for identifying opportunities to reduce electricity costs in residential and commercial settings.” – Zimmerman Electric Company

If that’s not incentive enough, the government sweetens the deal. Thanks to the Inflation Reduction Act, you can claim 30% of your energy audit’s cost – up to $150 – as a tax credit. But don’t wait too long; this credit expires at the end of 2025.

Finally, energy audits can even boost your property’s value. Energy-efficient upgrades identified during an audit can make your home or business more attractive to buyers. And when you implement the recommended changes, you might qualify for even more tax credits and rebates.

Up next, we’ll dive into the costs and considerations of tackling an energy audit yourself versus hiring a professional.

DIY Energy Audits: What They Cost and Where They Fall Short

How to Do Your Own Energy Audit

Conducting a DIY energy audit involves evaluating your home’s energy use with basic household tools. This includes tasks like checking for air leaks, inspecting insulation, and examining your HVAC system for inefficiencies.

Start by tackling the basics. For example, you can use an incense stick to detect drafts around windows and doors – just watch how the smoke moves to pinpoint problem areas. Go room by room, looking for gaps around window frames, worn-out weatherstripping, or drafts near electrical outlets. These small steps can reveal areas where energy is escaping.

Pay special attention to spots where energy loss is common. Check insulation in the attic, basement, and crawl spaces. Inspect your HVAC system for disconnected ducts or clogged filters. Don’t overlook your water heater – if it’s running too hot, it might benefit from an insulating jacket.

Some tasks, like working in the attic or repairing chimneys, might be beyond your skill level. In these cases, it’s wise to call in a professional. This initial DIY effort gives you a clearer picture of your home’s energy efficiency, but it’s just the first step.

DIY Energy Audit Expenses

Once you’ve identified problem areas, you’ll need a few tools and materials to fix them. While your time is free, here’s what you might spend to get started:

Detection and Monitoring Tools:

  • A Kill A Watt detector costs $22 and measures appliance energy use.
  • The Black & Decker TLD100 infrared thermal leak detector, priced at $49.99, helps spot temperature differences and air leaks.
  • Smart plugs and relays can monitor energy usage for various devices in your home.

Sealing Materials:

  • Caulk and weatherstripping are essential for sealing air leaks around windows and doors.
  • The Easy-Stop Weather-Stripping System is $74 per window, while foam gaskets for outlets cost just $0.10 each.
  • For fireplaces, a Draftstopper runs about $55.

  • Water-based mastic sealant and HVAC foil tape can patch ductwork issues.
  • Water heater insulating jackets cost between $10 and $20, and similar insulating blankets are available for older tank-style water heaters.
  • Sweep seals for exterior doors help block drafts from underneath.

Additional costs might include a fireplace sweep service, which ranges from $90 to $200, or a replacement refrigerator gasket, priced between $60 and $90.

“With a little knowledge and determination, you might be surprised by your next power bill.”

Where DIY Audits Come Up Short

DIY energy audits are a great starting point, but they have their limitations. While they can help you identify obvious issues, they often miss more complex problems that require specialized tools and expertise. For example, professional energy auditors use advanced equipment like blower doors, infrared cameras, and combustion analyzers – tools that most homeowners simply don’t have access to.

The U.S. Department of Energy highlights this gap:

“A ‘do-it-yourself’ home energy audit will not be as thorough as a professional home energy assessment.”

DIY efforts might also lead to costly mistakes. For instance, you could spend a fortune on new windows when better insulation would have solved the problem. On the flip side, over-sealing your home could create indoor air quality issues that require expensive fixes.

Another challenge is expertise. Professional energy auditors have the training to spot problems that a DIYer might overlook. They also provide specific, actionable recommendations instead of generalized advice. While professional audits involve upfront costs, they can reduce energy bills by 5% to 30% annually by pinpointing the most effective solutions.

Without tools like infrared cameras or blower doors, DIY audits often miss hidden insulation gaps, duct leaks, and even safety hazards. Professionals bring a level of precision that ensures you’re investing in fixes that deliver the most impact, rather than guessing at solutions that might not address the root issues.

Professional Energy Audits: Costs and What You Get

What Professional Energy Audits Include

Professional energy audits bring in specialized tools that most homeowners don’t have access to – think blower door tests, infrared cameras, and surface thermometers. These tools allow for a deep dive into your home’s energy efficiency.

Step-by-Step Thermostat Troubleshooting Process

Before diving into complex fixes, start with the basics: resetting your thermostat, checking the batteries, and inspecting wiring or sensor placement. These steps are organized from the simplest to the more involved solutions.

How to Reset Your Thermostat

Resetting your thermostat can fix issues like unresponsive displays, programming errors, or incorrect temperature readings. Essentially, this process restores the thermostat to its factory settings, clearing minor glitches that might be causing problems.

To reset, first, turn off the power at the circuit breaker. Then, follow the specific reset instructions for your thermostat model. For instance:

  • Honeywell Thermostats: Press the system button, hold the blank box in the center, and then press “done”.
  • Nest Thermostats: Press and hold the outer ring for 10 seconds until the screen shuts off, then release and press it again. The Nest logo will appear, confirming the reset.
  • Carrier Thermostats: Select “mode” on the main screen, set it to “off”, turn off the circuit breaker for 30 seconds, and then turn it back on. Finally, set the thermostat to your desired mode.
  • Trane Smart Thermostats (XL824, ComfortLink® II 850/1050, Link UX360): Make sure the HVAC system is idle, then navigate to Menu > Settings > Reboot on the thermostat screen and confirm. Alternatively, you can turn off the circuit breaker for 20–30 seconds and then switch it back on.

After resetting, reprogram your thermostat settings as needed, and move on to checking the batteries.

Check and Replace Thermostat Batteries

Weak or dead batteries are a frequent cause of thermostat malfunctions. Depending on your model, you might need AA, AAA, 3V lithium button-style, or 9-volt batteries – check your owner’s manual for the correct type. A good rule of thumb is to replace them annually, perhaps when you also change your carbon monoxide detector batteries.

Signs of low batteries include:

  • A flashing battery icon or dimmed screen
  • An LED light or low-frequency alert
  • A malfunctioning HVAC system

To replace the batteries:

  1. Remove the thermostat cover.
  2. Use a small flathead screwdriver to take out the old batteries.
  3. Insert new batteries, ensuring the positive and negative terminals match the markings inside the compartment.
  4. Reattach the cover securely.

If your thermostat is older or the batteries seem to drain quickly, inspect for corroded contacts or aging components. Note that some models, like the Nest Learning Thermostat, use batteries primarily as backup power.

Clean and Inspect Internal Components

Dust buildup can interfere with your thermostat’s calibration, leading to inaccurate readings and reduced performance. Regular cleaning can help keep it functioning properly.

Before cleaning, always turn off the power to your HVAC system at the circuit breaker. Remove the thermostat cover (you may need a screwdriver), and use a soft brush or compressed air to gently clean the interior. Avoid using liquid cleaners or chemicals, as these could damage the components.

For electromechanical thermostats, clean the bimetal coil with a soft brush and use a dollar bill to clean contact points. If you notice significant grime or corrosion, a small amount of rubbing alcohol can be used. Smart thermostats like the Google Nest typically only require light dusting.

Additionally, wipe the exterior with a damp cloth and check for visible damage. Make sure the thermostat is level on the wall, as improper positioning can affect its performance. Cleaning every few months is a good maintenance practice.

Once cleaned, check the wiring to ensure everything is secure.

Check Wire Connections

Loose or damaged wires can cause your thermostat to behave erratically or fail altogether. Start by removing the thermostat cover to access the wiring.

Inspect each wire for looseness, corrosion, or visible damage. Gently tug on each wire to ensure it’s securely connected. Look for corrosion, which often appears as green or white buildup, and check that all wire nuts are tight with no exposed copper.

Common issues include loose terminal screws, corroded connections, or wires that have come loose from their terminals. Tighten any loose connections carefully. If you spot damaged wires or extensive corrosion, or if you’re unsure about handling electrical work, it’s best to call a professional technician.

After securing the connections, replace the cover, restore power, and test the system by adjusting the temperature to see if the HVAC responds correctly.

Check Thermostat Location and Placement

The placement of your thermostat significantly affects its ability to read the room’s temperature accurately. Poor placement can lead to inefficient HVAC operation, uncomfortable temperatures, and higher energy bills.

The thermostat should be installed on an interior wall, away from direct sunlight, drafts, or heat sources like lamps and appliances. Ideally, it should be positioned 52–60 inches above the floor in a spot that represents the average temperature of the home. Avoid placing it near windows, doors, fireplaces, or air vents.

If your thermostat is on an exterior wall or in a location that misrepresents the room’s temperature, consider relocating it. Keep in mind that moving a thermostat often involves rewiring, which may require professional assistance.

Proper placement ensures the thermostat provides accurate readings, complementing the earlier troubleshooting steps.

Diagnosing Electrical and Wiring Problems

If basic troubleshooting hasn’t resolved your thermostat issues, the problem might be rooted in the electrical system itself. Faulty wiring, inconsistent voltage, or damaged connections can lead to unpredictable behavior that a simple reset won’t fix. Addressing these problems requires a careful and systematic approach to ensure safety.

Before inspecting any wiring or testing electrical components, always turn off the power at the circuit breaker. This step is crucial to avoid accidental short circuits or further damage to your HVAC system. Once the power is off, you can begin with a visual inspection and use a multimeter to check the system’s electrical integrity.

Inspect Wires for Damage

Worn-out or damaged wires are a common reason for thermostat malfunctions. Over time, wires can loosen, corrode, or sustain physical damage, disrupting the connection between your thermostat and the HVAC system.

To inspect the wiring, remove the thermostat cover to expose the terminals and wires. Look closely for any signs of trouble. Loose or disconnected wires may have slipped from their terminals, and damaged insulation might appear cracked or missing. Pay special attention to areas where wires bend or enter the wall, as these spots are prone to wear. Corrosion around the terminals is another red flag. If you find any issues, the affected wires may need to be repaired or replaced.

Test Voltage with a Multimeter

A multimeter is an essential tool for measuring power voltage in your electrical system. Set the multimeter to the appropriate voltage range – typically 50V AC for a 24-volt system. To test, access the wiring and place the red probe on the “R” terminal (the power wire) and the black probe on any other terminal. For a 24-volt system, the reading should fall between 22 and 26 volts.

To check internal components, switch the multimeter to ohms mode. If the reading exceeds 200 ohms, it could indicate a fault in the system. Voltage readings outside the 22-26 volt range might point to problems with the transformer or wiring, which may require professional attention.

When Wiring Problems Need Professional Repair

While some wiring issues can be handled with basic troubleshooting, more complex problems often demand the expertise of a licensed professional. Handling intricate electrical systems can be risky, and professionals have the training to ensure safe and accurate repairs. They also ensure compliance with local electrical codes and safety standards.

If you notice extensive wire damage, multiple loose connections, or voltage readings that don’t match your system’s specifications – or if your multimeter results are inconsistent – it’s a good idea to call in an expert. Professional repair costs typically range from $80 to $200, depending on local rates.

Fix Temperature Reading and Placement Issues

A thermostat that works electrically but delivers inaccurate readings or is poorly positioned can lead to uneven temperatures and higher energy bills. Fortunately, addressing both calibration and placement can solve these problems.

“Proper thermostat placement is crucial not only for your home’s overall comfort but also for energy use. A mislocated thermostat can gradually increase your monthly utility bills and create additional wear and tear for your HVAC unit.” – Quality Heating, Cooling, & Plumbing

Calibrate Your Thermostat

Getting accurate temperature readings starts with calibration. To check if your thermostat needs adjusting, place a reliable thermometer nearby and wait about 15 minutes for both to stabilize. If the readings differ by more than a degree or two, calibration is necessary.

Before calibrating, clean the thermostat’s cover and sensors, as dust buildup can interfere with accuracy.

For smart thermostats, refer to your user manual for built-in calibration tools. Many models allow you to adjust temperature readings directly through the settings menu. If no calibration option is available, try resetting the thermostat to its factory settings – this can sometimes fix accuracy issues.

For mechanical thermostats, locate the calibration screw or lever inside the unit. Adjust it incrementally, checking the temperature after each small change, until the readings align with your thermometer. Remember to allow a few minutes between adjustments to see the results.

“Regularly checking and calibrating your thermostat can help ensure that your home remains comfortable and that your heating and cooling system operates efficiently.” – Legacy Heating & Cooling

To keep your thermostat functioning at its best, check its calibration at least once a year. If calibration doesn’t fix the issue, the internal sensors might be failing, and professional assistance could be required.

Once calibration is complete, it’s equally important to ensure your thermostat is placed in the right spot for consistent performance.

Choose the Best Thermostat Location

Proper placement is just as critical as calibration for maintaining accurate temperature control. The ideal spot is typically on an interior wall, centrally located in your home, and positioned 52 to 60 inches above the floor. This height ensures the thermostat measures the air temperature where people live and minimizes the impact of external factors like drafts or sunlight. Choosing a room that’s frequently used helps the thermostat reflect your household’s comfort needs.

In multi-story homes, placing the thermostat on the first floor is often the best choice. Since heat rises, this location provides a more balanced reading for the entire house. Avoid areas with direct sunlight, air vents, doors, windows, or heat-producing appliances, and make sure there’s plenty of airflow around the thermostat.

If your thermostat’s current location is causing problems, relocating it to a better spot can significantly improve both your HVAC system’s efficiency and your home’s comfort. Consulting professionals, like Hydrodynamics, can help pinpoint the optimal placement for your thermostat and enhance overall system performance.

Sealing and insulating ducts can pay for itself in energy savings while extending the life of your HVAC system. Whether tackling this as a DIY project or hiring a pro, it’s one of the most effective upgrades for energy efficiency and comfort.

How to Seal an HVAC Duct with Mastic – Duct Sealant

Tools and Materials You’ll Need

Having the right tools and materials is essential for achieving a professional and durable duct sealing and insulation job. Each item plays a role in creating airtight seals and effective insulation.

Required Tools

To tackle air leaks, mastic sealant is your go-to solution. This thick, paste-like substance forms a durable seal that resists cracking or peeling over time. Pair it with UL 181-rated foil tape, specially designed for HVAC systems, as regular duct tape won’t hold up under the temperature fluctuations of HVAC systems.

A utility knife or duct knife ($20–$30) ensures precise cuts through insulation and tape, while a measuring tape ($5–$20) helps you size materials accurately. A brush or applicator is key for spreading mastic evenly across surfaces, and a staple gun ($20–$40) secures insulation to joists. You’ll also need a caulking gun ($5–$30) to apply sealant around vents.

“As part of insulation installation, you’ll use a combination of mastic sealant and foil tape to address any leaks you find.” – This Old House

For general tasks, keep a screwdriver set ($10–$30), adjustable pipe wrench ($10–$30), and pliers set ($15–$45) on hand for handling duct connections. A torpedo level ($20–$35) ensures everything stays aligned, while tin snips ($10–$35) make clean cuts through metal ductwork.

Once your tools are ready, it’s time to choose insulation materials that suit your system’s needs.

Insulation Materials

Fiberglass insulation is a popular choice for its thermal and soundproofing properties. Available in batts, rolls, and loose-fill forms, it offers R-values between R3.0 and R4.0 per inch. For humid environments, polyethylene foam stands out with its superior moisture resistance and an R-value of R4.2 per inch.

In hotter climates, reflective insulation helps by deflecting radiant heat, while mineral wool provides excellent fire resistance and sound absorption, with R-values similar to fiberglass.

Insulation Type R-Value Range (per inch) Available Forms
Fiberglass R3.0 – R4.0 Batts, rolls, loose-fill
Polyethylene Foam R4.2 Sheets
Reflective Insulation Varies Rolls, sheets
Mineral Wool R3.0 – R4.0 Batt insulation, boards

For tighter spaces, R6 insulation is a budget-friendly option, while R8 insulation offers better thermal performance but requires more room and investment. R8 ductwork can reduce power loss by about 2% compared to R6, making it a worthwhile upgrade.

Selecting the right insulation enhances your system’s efficiency, complementing the sealing process.

Safety Equipment

Safety should always be a priority when working with insulation and sealants. Materials like fiberglass, cellulose, and mineral wool can irritate the skin, eyes, and respiratory system. Additionally, some sealants release volatile organic compounds (VOCs), which can be harmful if inhaled.

Equip yourself with heavy-duty gloves to protect against insulation fibers, and wear safety glasses or goggles with side shields to shield your eyes. A respirator with proper filters is necessary to guard against hazardous particles – simple dust masks won’t cut it.

“Long-sleeved shirts and long-legged pants, gloves, and head coverings are generally recommended to protect against skin irritation when working with fiberglass insulation. In some cases, eye protection and respiratory protection may also be necessary.” – Occupational Safety and Health Administration

Add long-sleeve workwear to minimize skin exposure, and opt for steel-toe boots to safeguard your feet from injuries. If you’re working at heights, make sure to use fall protection gear. A complete Personal Protective Equipment (PPE) package typically costs between $85 and $275 – a worthwhile investment in your safety.

How to Seal HVAC Ducts

Sealing your HVAC ducts is a practical way to save energy and improve system efficiency. In older homes, as much as 10% to 25% of heated or cooled air can escape through ductwork, and in some cases, that figure can climb to 50% before the air even reaches your vents. Follow these steps to tackle those costly leaks.

Find and Identify Leaks

Start by running your HVAC system at full power to expose any air leaks. Focus on areas where ductwork is most accessible, such as attics, basements, crawl spaces, and utility closets – these spots are often the culprits for leaks.

“The easiest way to find duct leaks is to inspect exposed ductwork and feel for air escaping at joints, seams, and connections while your HVAC system is running.”
– Elisabeth Beauchamp, Senior Staff Writer, Today’s Homeowner

Use your senses to locate problem areas. Feel around joints and seams for escaping air, and listen closely for whistling sounds, which often indicate small gaps. Pay special attention to duct elbows and joints, as these are common trouble spots.

Sometimes, visual signs can point to hidden leaks. Dust buildup around vents might mean leaks are pulling in debris from attics or crawl spaces, while moisture on ducts could indicate airflow issues or escaping air.

For a more precise approach, try using a smoke pencil or hold a tissue near seams to detect airflow. These tools are affordable and can be found for about $30 at most home improvement stores.

If your ducts are hidden behind walls, floors, or ceilings, a professional pressure test might be necessary. This service typically costs between $200 and $400 for a standard home.

Once you’ve identified the leaks, the next step is to prepare the duct surfaces for sealing.

Clean and Prepare Surfaces

Proper surface preparation is key to ensuring sealants stick effectively. Begin by cleaning and drying the ductwork thoroughly, as dirt, dust, and grease can prevent sealants from adhering properly. Use a rag and a mild cleaner to wipe down seams and remove debris. This step may seem small, but it’s crucial for creating a strong bond.

Make sure the surfaces are completely dry before applying any sealant. Moisture can compromise adhesion and lead to seal failure.

Apply Mastic and Foil Tape

With the leaks identified and the surfaces prepped, it’s time to seal the ducts. Mastic is widely regarded as one of the most effective materials for this job. When applied correctly, it forms a durable barrier against air leaks. For added durability, many professionals pair mastic with specialized foil tape.

Apply a generous layer of mastic over the seams and joints, extending the coverage a few inches beyond each leak to ensure all gaps are covered. For larger gaps, mastic tape is a solid option [25, 27]. When using tape, press it down firmly to avoid wrinkles or bubbles, as these can compromise the seal [25, 27].

Allow the mastic to dry completely – this usually takes 24 to 48 hours – before running your HVAC system. Once dried, use a smoke pencil or an incense stick to check for any remaining leaks. If needed, apply additional sealant.

Sealing your ducts can cut heating and cooling efficiency losses by up to 20%. Taking the time to follow these steps can lead to noticeable energy savings and lower utility bills.

How to Insulate HVAC Ducts

Once you’ve sealed your ducts to prevent air leaks, the next step is insulation. Properly insulating your ducts helps to reduce energy loss and moisture buildup, especially in unconditioned spaces like attics and basements, where temperatures can vary significantly.

“Insulating your ductwork is more than just a home improvement task – it’s an investment in your home’s comfort and energy efficiency.”
– This Old House

The key to effective insulation lies in accurate measurements and careful installation techniques.

Measure and Cut Insulation

Start by measuring the circumference of each duct, adding 2 extra inches to account for overlap. For instance, if a duct measures 12 inches around, cut the insulation to 14 inches wide. This overlap ensures a snug fit and better sealing.

Next, measure the length of each duct run individually – dimensions can differ throughout the system. Use a sharp utility knife or heavy-duty scissors to make clean, precise cuts. Leave a slight overlap at the ends of each section to prevent gaps, which can lead to thermal bridging.

Wrap and Secure Insulation

Wrap the cut insulation around the ductwork, ensuring you don’t compress it, as this can reduce its effectiveness. Overlap the seams by 2 inches to create a tight barrier that minimizes air and moisture infiltration.

Use foil tape to secure the seams, pressing it firmly along the entire length of each overlap for a continuous seal. Pay extra attention to the ends of each insulation section – seal them directly to the duct or the adjoining insulation piece. Richard Trethewey from This Old House highlights the importance of sealing every joint and seam to ensure maximum efficiency.

Insulating Ducts in Unconditioned Spaces

Ducts located in unconditioned spaces face extreme temperature fluctuations, which can lead to significant energy losses. For example, ducts in an unconditioned attic can waste up to 20% of your furnace or air conditioner’s output, with losses climbing to 28% on particularly hot days.

Moisture is another challenge in these areas, especially in humid climates where condensation can form on duct exteriors during summer months. To address this, include a vapor barrier when insulating ductwork in attic spaces.

For accessible ducts in unconditioned areas, start by applying 1 inch of closed-cell spray foam. This not only seals seams but also provides thermal and moisture protection. Once the spray foam is in place, add a layer of loose-fill cellulose insulation for extra thermal efficiency.

Additionally, ensure that ductwork in these spaces stays in direct contact with the ceiling or attic floor rather than being suspended. This positioning helps stabilize temperatures and reduces the risk of condensation. When insulating ducts in attics or crawl spaces, tightly wrapping the insulation around the ducts is essential for maintaining energy efficiency and ensuring your HVAC system performs at its best.

Considering that indoor air can be two to five times more polluted than outdoor air, sealing your ducts can make a big difference.

“Sealing improves indoor air quality by preventing dust and contaminants from entering the ducts.” – West Coast Chief Repair

Sealing and insulating also help eliminate hot and cold spots, ensuring consistent temperatures and better comfort throughout your home. Plus, your HVAC system won’t have to work as hard to compensate for energy losses, which means less wear and tear. Over time, this can extend the lifespan of your system and even lower maintenance costs.

Benefits Comparison Table

Benefit Category Before Sealing/Insulating After Sealing/Insulating Potential Savings
Energy Efficiency 20% efficiency loss due to leaks Efficiency improved by up to 25% Up to 25% efficiency increase
Utility Costs 25–40% energy waste Optimized energy usage 20–30% cost reduction
Air Quality Pollutants circulated throughout home Reduced indoor pollutants Cleaner air for allergy sufferers
Temperature Control Hot/cold spots and uneven heating/cooling Consistent room-to-room temperatures Improved comfort
System Lifespan Increased wear from overworking Reduced strain on equipment Longer HVAC system life

The financial perks don’t stop at monthly savings. Properly sealed ducts can reduce your heating and cooling demands, potentially allowing you to downsize to a smaller, less expensive HVAC system when it’s time to replace it. That could mean thousands of dollars in upfront savings.

For homes with ducts in unconditioned spaces like attics or crawl spaces, sealing and insulating is especially cost-effective. These areas are prone to extreme temperature fluctuations, so addressing leaks here can significantly boost both energy efficiency and comfort.
