"Repairing Central Air Conditioning System"

"Excellent work. Nick and Ryan were professional, friendly and thorough. Big difference in air quality in my home. I have recommended them to my friends and family."

"Replaced capacitor. Still didn't work, so we were looking at ac replacement. Before we did, technician continued to experiment by cooling of the compressor with the garden hose and it worked! Saved me thousands in replacement costs."

"they checked the central air to make sure it was in good condition ."

"The air conditioner is working fine."

"We had a great experience with Four Seasons Heating & Air Conditioning during our recent replacement of our furnace and AC unit. They were very professional and completed the job on time and answered all of my questions. Would recommend them for our Heating, Air Conditioning, Plumbing and Electrical needs."

"We called United Heating and Air Conditioning for an annual furnace inspection for our new home. They scheduled quickly and easily. We then had a conflict and they re-scheduled just as easily. When they inspected the furnace it turned out it was extremely old and no longer safely operable. We required an emergency replacement. This was in November and we didn't want to be without a furnace. United Heating and Air Conditioning was able to come the next day (!) and install a new furnace. They took care of the installation, confirmed it worked, and hauled away our old furnace. They were quick and professional and stuck exactly to the quote. We were extremely satisfied and will definitely be reaching out to them when it's time to check (and possibly replace!) our air conditioning unit. Highly recommend!"

"I called yesterday and Ron came out today. This is the 3rd time he's helped us with furnace or central air issues. He found a sticker wrapper by the filter and found that the filter was the wrong size. He's always really friendly and professional.

"After the tech diagnosed the issue with the AC. It was determined that I needed to run a new line from the AC condenser on the roof to the furnace in the basement. Seeing how the line within the wall was cut. Not sure how that happened but as a service technician myself I have ran plenty of low voltage wire, cable lines, and Cat 5/6 wiring for internet services. After assisting the tech with running the wires. He wants to overcharge me. I asked him if he normally has customers assist with his work and then charge them extra money for there help. And I had to use my own drill to finish the job. I will not be recommending him for anything. Sorry bro you can keep it moving."
