"Very professional and meticulous with his work. He layer down a plastic sheet where he worked. He even pulled out the pellet stove out of the Fire place and cleaned behind it. I believe we have used him for 3 years now. I would not use any one else! For the work he accomplished his price was very reasonable."

Heating and Air Conditioning FAQs, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).
