"Repairing Central Air Conditioning System"

"Great work and they cleaned every vent and return in our 6000 foot home and price was very fair. We had major construction and dust in ductwork. Air feels cleaner tonight."

"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."

"The company is so cool handled and installed my new ac unit with class !!! They are my main peeps to call for service when I need it"

"They came even at a busy time to assess what needed to be done. I was given plenty of information and my questions were answered. I expect tomorrow’s furnace instsall will go just as well. I have had ac units and furnaces installed by Miller and been very pleased. A fine company."

"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."

"For DC/ Northern VA: Best price in the area. Very methodical, evaluated the ducts as he worked, very knowledgeable. Dryer duct cleaned as well. Showed up 2 hrs late, so ensure you have a full day for the job to be completed."

"Although they were booked up Alliance Repair Services made time to come out to our house and evaluate the issue with our refrigerator. Once it was determined the issue, the repair tech found what we needed and went to get it. With other appointments he needed to do as well, again we were fitted into their tight schedule to come back sameday to fix and get our refrigerator working again. Great Job!!"
