"Andrew and his assistant were very professional in their approach to cleaning our air ducts and dryer vent. The services they provided were totally consistent with how they describe their approach to the service they provide. This included the very helpful before and after pictures taken which would convince anyone of the need to have this work performed in their homes."

"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 were able to send out a tech to repair our AC pretty quickly (within a few days), even though this was during a bout of unusually high temperatures. The tech arrived towards the end of the given arrival window; even though he was still within the window, they called me that day to let me know he would be later rather than earlier, which was nice. The tech diagnosed the issue, and discussed options with me and fixed it (low line refrigerant, possible leak). All that was great, and prices seemed reasonable. The only negative part of the experience is that there was an extra charge to de-ice the frozen interior coils. I could have done that in advance if I knew I was supposed to (the tech seemed surprised I hadn't, or that I wasn't told to). Maybe that's obvious to others, but it's not that big of a deal, just an an annoying extra cost."

"We were experiencing problems with our central air conditioning unit. It was running, however, it did not cool the condo fast enough. The Four Seasons Technicians arrived on time, very professional, thorough explanation of what was wrong with the unit, and provided solutions on how to fix the unit. He was very helpful in helping me negotiate for a new coil and A/C unit. He was dressed in protective covering during COIVD-19. I would use Four Seasons Heating & Air Conditioning again. I was very happy with their service."

"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."

"Gentlemen arrived promptly and got right to work vacuuming and cleaning overhead air vents. He described quality of each one as he worked on it. Did not use brush since vents would have been scratched due to the material. I appreciated that."
