Heating and Air Conditioning FAQs, answered by experts

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.
