Best Heating & Air Conditioning / HVAC In Wallingford

“I called them and in just a few days they came out to fix my leaking drain. Professional, friendly, and a fair price. On top of that, he took time to clean and even vacuum when he was done! Highly recommended.
Thank you!“

“We had a leak from our 43 year old HVAC system that took me awhile to notice. While there wasn’t inches of water, it was enough to soak a portion of the carpeting in my basement. I called Servpro and within a few hours, they had a remediation team at my door. Asim & Claudio vacuumed up the moisture, cut back carpeting, removed padding, and placed humidifiers and fans to dry up the rest. They returned again, this time it was Asim & Chelly, and they cut out some Sheet Rock and took out the remaining carpet, padding, and tackless. They disinfected the area and swept and vacuumed the area. They also placed a plastic barrier in my upstairs living area before pulling up the carpet on the stairs to help keep the dust down. Excellent job and now I am looking forward to working with the Construction crew. Expecting the same excellent service.“

“Paul came highly recommended and I can see why! He came out within 24 hours and quickly got my heat working in about 15 min after two other companies couldn't find the problem. Now me and my family are warm and comfortable again for a very reasonable price. I will never use anyone else for my HVAC needs. Thanks Paul!“

“For timeliness, these guys were second to none. I called, and they happened to have an opening the very next day. My wife works from home and I was away that day. She felt secure with Andrew and Alex. Their professional and friendly demeanors enabled her to feel safe home alone; and undisturbed for the most part while she worked her job, and they worked theirs. We had sensitivities to stuff coming out of the ducts prior to NAQS's arrival. After their cleaning and sanitizing of the ducts and vents, the atmosphere was markedly improved. The air is significantly cleaner, fresher.I would give them 5 stars, but they had promised pictures, which we haven't ever received. I'd be happy to amend it to 5 stars if the photos happen to show up in my customer portal. :-)“

“Tom and his crew just installed our new heat pump HVAC system, 2 1/2 days in our very hot attic. They are neat, knowledgeable, on time, and a pleasure to have in your home. Got the system running before this wicked heat. Couldn’t be happier with the work, highly recommended!“

“John and his son Chris are always the best. I’ve been using them for many years. John has never done me wrong. I can’t recommend him and his son enough. They are very knowledgeable and trustworthy. They will do the work right and save you money when possible.“

“Had our furnace tuned up for the season by Chris today (09-02-2025), always a professional job and pleasure to work with. Can't recommend enough.“
