Heating and Air Conditioning questions, answered by experts

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.
