Heating and Air Conditioning questions, answered by experts

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.
