Signs You Need an AC Replacement

It’s important to recognize the signs that your air conditioning system may need to be replaced. Here are some key indicators:

  • Age: If your AC unit is more than 10-15 years old, it may be nearing the end of its lifespan.
  • Frequent Repairs: If you find yourself constantly calling for repairs, it may be more cost-effective to invest in a new system.
  • Increased Energy Bills: An inefficient AC unit can lead to higher energy consumption and increased utility bills.
  • Uneven Cooling: If some rooms in your home are too warm while others are too cold, it could be a sign that your AC system is struggling to distribute air evenly.
  • Strange Noises: Unusual sounds like grinding, squealing, or rattling from your AC unit may indicate serious issues that require a replacement.

If you experience any of these signs, it’s time to contact Mannix Heating and Cooling for a professional assessment of your air conditioning system.

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...

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!
Customer Reviews
Before dealing with Mannix I used two very well-known and “reputable” HVAC companies who did nothing but rip us off over the years. I was frustrated and found Mannix Heating & Cooling about 10 years ago. They installed a new HVAC system in my old home, and installed a water...

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...
