Most people don’t think about their heating and AC units until they break or become outdated. Depending on the time of the year, a system malfunction can result in some uncomfortable temperatures at home. Fortunately, knowing these four simple points about your HVAC system can go a long way toward keeping it running smoothly and lowering energy expenses. 

What You Should Know About Your Heating & Cooling Units

1. When to Change the Air Filter

The air filter keeps healthy airflow circulating. If it’s dusty or clogged, the HVAC system has to work harder, driving up energy costs. If you leave it clogged long enough, the system can break down. To ensure this doesn’t happen, change the air filter every two to three months, depending on how often you use it.

2. Which Noises Are Unusual

If your AC unit or furnace makes strange sounds, like clanking, banging, or chirping, something might be wrong. These noises are easy to distinguish because they differ from the typical droning white noise systems make. The sounds may suggest you need to hire a repair specialist to check and repair the system. The sooner you tend to this issue, the less likely you must deal with the cost of a replacement.

3. When to Schedule Maintenance

Though you seldom deal with repairs or breakdowns, you should still stay involved with the system’s maintenance; it can’t remain functional on its own. Schedule service at least twice per year, preferably during the spring for cooling and fall for heating.

4. Useful HVAC Terms

Though HVAC contractors and technicians speak to clients in layman’s terms as much as possible, the nature of the job often requires plenty of jargon. You should at least know about the compressor, condenser, and evaporator coil so you can communicate clearly.

The compressor component powers the heat-transfer cycle by compressing the refrigerant and circulating it through the coils. A condenser turns refrigerant from gas to liquid, moving heat through your home; this is usually found in outdoor units. The evaporator coil blows cool air into your home.
