Heating and Air Conditioning questions, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.
