Heating and Air Conditioning questions, answered by experts

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

No. With a ventless portable AC system, you don’t need to vent anything out the window—but it will be harder to circulate the hot air from the room without one, so you’ll need to come up with another solution, like placing a fan near a warm spot and facing it towards and open water to push the hot air out.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

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.
