Air conditioning systems can experience a variety of problems, ranging from minor inconveniences to complete breakdowns. Some of the most common issues include:

  • Insufficient Cooling: If your AC is running but not providing adequate cooling, it could be due to a variety of factors, such as low refrigerant levels, dirty air filters, or a malfunctioning compressor.
  • Strange Noises: Unusual sounds like squealing, grinding, or rattling can indicate issues with the fan motor, compressor, or other mechanical components.
  • Leaking Water: A clogged condensate drain line or a frozen evaporator coil can cause water to leak from your AC unit, potentially causing damage to your home.
  • Uneven Cooling: If some rooms in your home are cooler than others, it may be due to a problem with your ductwork or an improperly sized AC system.

At Mannix Heating and Cooling, our experienced technicians have the knowledge and skills to diagnose and resolve these and other AC issues quickly and effectively.

We were in desperate need of a fix on our AC system during the July heatwave. The issue arose on a Saturday. Mannix came to the rescue in short order, fixed it, and at a reasonable price. Silvio G was the technician, and he was GREAT. We would definitely use Mannix again!

I contacted Mannix from a referral of a friend who has benefitted from the excellent service this company provides. I found out a couple I know in Vienna had their heat pump stop working a few months ago and needed to be replaced. I called up the Mannix office later in the day on Monday 11/30/20...

My 24-year-old heat pump finally decided to stop working. I sent a request for a replacement estimate late one night through the Mannix website and received a phone call early the very next morning to set up an appointment. Eric Holzworth stopped by my house the next day to go over my options. He...
