Best Heating & Air Conditioning / HVAC In South Windsor

“Stacy James was professional and personable. He did an excellent job. Worked with me, as I wanted to wash all the register covers as he went through the house removing them.“

“Sending a very happy, appreciative review.. The first time Omni came to our home was to service our furnace.. prior to their visit three other HVAC companies came over and we didn’t receive the results we needed. No one could figure out why we were not receiving air conditioning air flow on the second floor.. they fixed the problem instead of telling us to buy a new furnace. All it needed was a new fan/motor.. they are honest and trustworthy.
The second visit was for our hot water heater which was not producing hot water.. once again they did not try to sell us a new hot water heater.. it simply needed to be serviced for the season.
A wonderful company with integrity that puts its customers first!“

“Jeff Prewitt did an outstanding job! He was professional, knowledgeable, and courteous from start to finish. He took the time to explain everything clearly, completed the work efficiently, and made sure everything was working perfectly before he left.

I’d also like to recognize our sales representative, Luis Coppola. Luis was friendly, informative, and never made us feel pressured. He answered all of our questions, helped us choose the right solution for our home, and made the entire process smooth and stress-free.

Together, Jeff and Luis provided excellent customer service and made this a great experience from beginning to end. I highly recommend Glasco Heating and Air Conditioning, Inc. to anyone looking for honest, reliable HVAC service. Thank you both for your outstanding work!“

“I’m writing this review 10 months after we had Advanced Heating and Air Conditioning install Mitsubishi Electric HVAC units in our split-level home in South Windsor, and we couldn’t be happier with the results.

Last July (2025), we were tired of dealing with window units and wanted a more comfortable, long-term solution for cooling our home. Looking back, investing in this system and choosing Advanced Heating and Air Conditioning was absolutely the right decision.

From mounting the outdoor unit on our house siding to completing the attic installation and replacing the attic fan, every part of the job was done with incredible care and attention to detail. We’re especially glad we added the heat pump, since it allowed us to take the chill out of the house during the early spring months without needing to turn on the furnace.

Mike and his entire team were professional, courteous, and thorough throughout the entire process. They cleaned up at the end of each day, clearly explained the work they were doing, and made sure everything was completed the right way. We had five ceiling vents installed and our attic fan replaced with a return vent, which required cutting into the ceilings, and they did an excellent job. Everything looks great, and we’ve had zero issues.

I would highly recommend Advanced Heating and Air Conditioning to anyone looking to upgrade the HVAC system in their home.“

“We have used imperial at least 3 times and I am always impressed by their professionalism and quality of their work. They are responsive and keep us updated throughout the job. They were very helpful recently when we had a leak in our basement. Another plumber wanted to rip down a wall to replace a whole section of pipe. Imperial was able to do it without any cosmetic damage and for a fraction of the cost. Very satisfied.Services: Plumbing leak detection“

“Quick response to an emergency heating system repair. Thank you to Atlantic Mechanical Services of South Windsor, CT. They are always on time and very knowledgeable of my heating system. I was without heat and hot water this morning and they arrived that same morning to do the repair.“

“Lightning quick response time, friendly customer service, and fair pricing. Highly recommended!“

“My steam radiators started clanging loudly & spewing muddy water. I was surprised & relieved to get a service appointment the same day during this long spell of frigid weather with more to come. Jeff showed up early & quickly diagnosed & fixed the problems. Impressive knowledge & skill & he didn't mind answering all my questions & explained everything very clearly.“

“Alan and Aiden were able to rescue me in advance of the heatwave. Very professional crew. Our problem turned out to be a starting capacitor, which is great news. Too many people now would just say “oh yeah, that’s a bad compressor” and then gouge the customer for a few grand. Super thankful for the honest work.“
