“Look no further - if you're trying to find the company to use, this is it. Could not have been a better experience. I reached out for help with my furnace situation and setting an appointment was easy and pleasant. CC was added on file which also meant I didn't have to worry about it later for payment, text was sent 20 min before arrival, and arrival window was accurate. Mark came out to fix an issue with my furnace and was fantastic. Everything was quick and easy and they got my thermostat controller issue working enough for my needs while they wait on a part that needs replacement. I also had a ton of questions since my house is old and has some unique issues, and he not only answered everything but gave other suggestions and recommendations. Mark also walked me through the follow up process for when they receive the part and can come out again. Obviously needing help is not always the best because you're dealing with a crappy situation, but they not only turned this into a positive experience but were quick to get us back up and running. Thanks again!!”

“If oil furnace abuse was a crime, I'd be writing this from Sing Sing. I've neglected my Weil oil furnace for a few years and it finally had enough of my abuse. So after looking for a local highly rated company to service my house in hamden we called nathan, and a wonderful gentleman named Ricardo came over to service the furnace id unknowing been abusing for years. Now nobody likes hearing youre major appliances are in need of multiple life saving measures and nobody likes spending money, but Ricardo showed me everything that was caked in black tar or oozing muddied oil, he kept a running tally of my expenses so I wouldn't stroke out with the final number and he stayed to walk me thru everything and gave me a rudimentary idea of how this heater id owned and abused for years actually worked. On a Friday at rush hour no less. So the money spent has already brought forth an amazing hot shower and for once I have complete confidence in the work and integrity of a contractor. Thank yoy A&S nathan and especially thank you Ricardo for your patience, your explanation and your ability to deliver news i was fearing in the most human and understanding of ways. Quality human being, fantastic technician and a quality company. I highly recommend using them when you're done having your brother in law fix your furnace, or are worried you'll receive a fly by night poorly done job. They did a grest job at a fair price. Thanks guys.”

“Highly recommend A&S Nathan Heating & Cooling LLC. Hot water tank sprung a leak over night. Called the office when they opened. Toni was a delight to speak with. Friendly and upbeat. Hard to find that in customer service these days. Technician came out walked me through the whole process. In no time at all they were done with nothing left behind. Clean and professional. A++ rating from me.”

- Nick Franzago

“Can't say enough about this company. Awesome service from first call to fixing my AC. When all other local companies told me two weeks, A&S Nathan did the job immediately and they did it for a reasonable price. Will definitely be using them again in the future because they actually CARE.”

“Al Nathan went above and beyond to diagnose a problem with my duct work and a vent that was not working. He and his crew were professional and completed the work promptly and efficiently. His prices can’t be beat but beyond that is his compassion and dedication to help figure out the problem and work with the customer with delivering the best possible outcome. 5+ stars to Al Nathan and company!!”
