Top HVAC System FAQsYour HVAC system is one of your biggest sources of comfort in the Indianapolis area’s chilly winters and warm summers. Understanding how it works will help you stay comfortable while minimizing your energy bills and repair issues.

How often does my system need professional maintenance? Both your furnace and A/C should be professionally cleaned and tuned up once a year. The maintenance jobs your technician will perform during this routine annual inspection keep up the system’s efficiency and head off malfunctions.

How should I care for the air filter? Once a month, remove the filter and hold it up to the light. If you can’t see light shining through, replace the filter. Standard fiberglass filters usually last only a month, but high-efficiency pleated filters last longer.

What kind of care do my air ducts need? Ducts can remain perfectly clean for many years. That said, there’s always a chance they can develop a problem with moisture, mold or pest infestations, or sustain damage. For this reason, have your ducts professionally inspected every five years to check if they require cleaning.

What can I do to improve the system’s efficiency? To maximize efficiency, change your air filter on schedule, keep your outdoor condenser unit and indoor evaporator coil clean, and never skip routine professional maintenance. Keep your air registers clean and unobstructed.

Using a programmable thermostat to manage your temperatures lets you control your heating and cooling bills while still staying comfortable. Making sure your home is well air sealed and insulated also helps your furnace and A/C work more efficiently.

How long will my system last? You can expect your air conditioner to last 12 to 15 years and your gas furnace to last for up to 25 years. With each passing year, however, your HVAC system loses some of its efficiency. Once your system is 10 years old, it’s a good idea to start shopping around for an upgrade.
