Heating and Air Conditioning questions, answered by experts

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma.

You should have your AC coils cleaned once per year. To keep your AC unit in tip-top shape, consider cleaning your coils twice yearly—before and after air conditioning season. That way, the pro will remove any dust, dirt, and debris that has built up over the winter and catch new grime that accumulated during the summer. Additionally, if you’re handy, you can tackle any in-between cleanings yourself with a special fin comb.
