Replacing your air filters regularly is key to keeping your HVAC system running smoothly and lasting longer. Clean filters prevent dust and debris from clogging important components, reduce strain on the system, and maintain proper airflow. The first step is figuring out how often to change them based on your household’s needs.

The replacement schedule depends on factors like indoor air quality. For example:

  • A single-person household might need a change every few months.
  • Homes with pets or high activity levels may require monthly replacements.
  • Vacation homes typically need less frequent changes.

Choose filters with the right MERV rating for your system. Filters rated between 8 and 13 work well for most residential setups, offering good filtration without restricting airflow too much. However, using filters with higher ratings can strain your system if it’s not designed for them.

To stay on track, mark your calendar for filter changes, check them periodically, and keep extras on hand. Always follow the directional arrows when installing new filters.

A clogged filter makes your HVAC system work harder, which can lead to higher energy bills and potential damage. If you’re not sure which filter or schedule is best for your setup, Hydrodynamics Inc. can help with tailored advice based on your system and usage.

3. Keep Air Ducts Clean

Dust and debris in your air ducts can block airflow, making your system work harder and lowering its efficiency. Look out for signs like dust buildup around vents, inconsistent temperatures between rooms, or musty smells – these often indicate it’s time for a professional cleaning.

Here are some signs your ducts might need attention:

  • Dust collecting around air vents
  • Uneven heating or cooling across rooms
  • Musty smells coming from the vents

DIY cleaning usually isn’t enough to tackle the hidden buildup inside ducts. Professional services, like those offered by Hydrodynamics Inc., use specialized tools to thoroughly clean your air ducts without causing damage.

If you notice any of these issues, don’t wait – schedule a professional duct cleaning to keep your system running smoothly.

4. Use a Smart Thermostat

A smart thermostat helps lower energy bills and reduces wear on your HVAC system by maintaining steady temperature control and limiting unnecessary use.

Here’s what makes it effective:

  • Automated scheduling: Keeps your system running smoothly without constant manual adjustments.
  • Learning capabilities: Adjusts to your daily habits, cutting down on frequent on/off cycling.

By preventing short cycling – when your system turns on and off too often – a smart thermostat supports longer, more efficient operating cycles.

For the best results, adjust temperatures gradually following the manufacturer’s instructions. It’s also a good idea to have a professional handle the installation and calibration to ensure everything is set up correctly.

Adding a smart thermostat is a simple way to enhance your system’s performance while pairing well with regular maintenance.

5. Keep Outdoor Units Clear

Make sure your outdoor HVAC unit has proper airflow. When debris builds up, it forces the system to work harder, which can lead to more wear and tear and a shorter lifespan.

Maintain at least 2 feet of space around all sides of the unit. Regularly take these steps to keep the area clear:

  • Remove grass clippings, leaves, and twigs from around the unit
  • Trim back shrubs and plants nearby
  • Clear snow and ice during winter
  • Keep storage items away from the unit

Check the top of the unit for debris, especially after storms. Leaves and other materials can fall through the grille and block internal parts. You can gently clean the exterior, but avoid using pressure washers – they can damage the delicate fins.

Using a protective cover in the fall can help keep leaves out, but be sure to remove it before using the system.

Inspect the base of the unit to ensure it’s level and stable. An uneven foundation can cause vibrations that wear down components faster. If the concrete pad is settling or cracking, have a professional check it out.

For best results, schedule professional cleaning of the condenser coils at least once a year. This removes dirt and grime that regular maintenance can’t handle, improving heat transfer and system efficiency. Stick to these steps, and your unit will run smoothly until its next professional inspection.

Leave internal cleaning and repairs to the experts.

6. Fix Duct Leaks and Add Insulation

Sealing and insulating your ducts is key to keeping your HVAC system running efficiently and lasting longer. When air leaks out or insulation is lacking, your system has to work harder, which can wear it out faster.

Check your ductwork by looking at accessible areas like attics, basements, and crawl spaces. Look for gaps or disconnects where air might escape. If you spot leaks, use duct-specific sealing products to close them up. Adding insulation to the ducts helps keep air at the right temperature, reducing energy waste and improving system performance.

Taking these steps can help your HVAC system run more efficiently and last longer.

7. Check Home Insulation

Your home’s insulation plays a big role in how efficiently your HVAC system runs and how long it lasts. If your insulation isn’t up to par, your system has to work overtime, leading to quicker wear and tear.

Here are the key areas to focus on:
