Heating and Air Conditioning questions, answered by experts

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

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.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.
