Heating and Air Conditioning questions, answered by experts

An AC compressor is one of the most expensive parts to replace on an AC unit if it breaks. You’ll pay up to $2,300 if you need a new one. If your AC is blowing warm air, there doesn’t seem to be a lot of air coming out of the ducts at all, or the unit cycles on and off a lot, you may have a broken compressor. Call a pro to check out your system. 

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
