An efficient HVAC system can keep a home comfortable year-round while using the least amount of energy possible. Scheduling preventive maintenance with an HVAC contractor and caring for your unit will help keep it efficient. Here are a few ways to lower your bills and improve your heater’s performance this season.

How to Make Your HVAC System More Efficient

1. Change the Filters

Airflow is reduced when your HVAC filters get dirty, so the system has to use more energy to push air through and maintain your desired temperature.

Check the filters once a month by holding them up in front of a light source. Change them whenever you can’t see light through the debris. Typically, this will be every one to three months. If you have allergies or pets, you may need to replace filters every month.

2. Use Smart Technology

For example, if you forget your heater on after leaving for work, you can access your system and turn it off from your office. Some smart thermostats also include sensors that detect movement or work on pre-set schedules, activating your HVAC system only when people are home to minimize waste.

3. Insulate

Treated air is often lost through ducts. Insulating them traps air inside, reducing waste and minimizing strain on your system. If an HVAC contractor determines your ducts have leaks, they might use duct sealant or metal-backed tape to seal the gaps.

Insulating parts of your home that are connected to the outside, such as exterior walls and the roof, will also prevent heat from escaping. Typically, new insulation needs to be added every 20 to 30 years, or whenever a part of the house sustains water damage.

4. Get Regular Inspections

Annual HVAC inspections ensure your system works at peak efficiency. During service, a professional checks that the electrical connections are safely wired, the condensate drain isn’t blocked, and the refrigerant pressure is at the right level to absorb heat.

If they find an issue, such as a refrigerant leak, they will provide prompt repairs or replacement to prevent energy waste and safety concerns. If you need to have your unit replaced, choose an option certified by EnergyStar®.
