"Y and M Air Duct cleaning provided an important service in a way that was transparent and professional. Our house is noticeably cleaner as a result of the service. They were punctual, polite and clean. They did not cut corners and showed me what they were doing and cleaning every step of the way. The world would be better if more contractors had Y and M's work ethic."

Air Conditioning FAQs, answered by experts

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.
