Excellent Workmanship

"Thanks, Al and team. Called today because my water heater flooded the basement / playroom. So responsive... They came right out, delivered a new one, installed, and removed the old one like clockwork. Excellent workmanship!"

- Dan, Shelton


The Real Deal!

"Al and his team are top notch. Our 15-year-old central air compressor needed replacing during a heat wave. Al and Jake had the new unit up and running within a few hours on a Monday morning. Very professional staff all around and we will continue to use them for future services. This co. is the real deal!!!!
Thank you for your prompt, excellent service, and reasonable prices!!"

Reliable and Trustworthy Company

"I own a condo in Shelton and need to find a reliable and trustworthy company to perform repairs, replacement, and provide me with a service contract for my oil burner and water heater. I found A&S Nathan Heating & Cooling. I am very pleased with how easy it was doing business with this company. From the start, I advised them I was living in another state and needed A&S to take a look at my mechanicals in my condo that I am renting. They were quick to react, polite, and very professional.
A&S Nathan Heating and Cooling came in performed all of the work and had all my new parts and replacement ready to go under three hours. I received a call back from the owner to advise me all the work was completed…
I will continue to use A&S for my future work and servicing."

Extremely Prompt Response

"Extremely prompt response! I waited over 7 hours for a local company I called directly (who did not respond) before I called “Service Magic” and was put in contact with “A & S Nathan.” They were so prompt, they called me while I was still on the phone with “Service Magic!” A & S was out to fix my problem in less than 45 min. Time for them on the job was about an hour and everything was fixed. All of this happened on a day of a very bad snow storm. Great job guys! Thank you very much."

Service Contract From A&S Nathan Heating & Cooling

"The last several years, we’ve purchased our oil from American Heating and Oil in Trumbull, and our service contract from A & S Nathan Heating and Cooling in Shelton. American doesn’t offer service contracts, which is why to use A & S Nathan for that. America’s oil rates are very competitive, we just got a delivery at 2.59 a gallon. A & S Nathan charges $200.00 for an annual contract, which includes 24-hour emergency service and an annual cleaning. We’ve had to call them twice with furnace issues, and both times they dropped everything and came right over."

- Joan D. in Milford, CT


Pleasure Working With the A&S Nathan Team

"It was a pleasure working with the A&S Nathan team. From the initial inspection / consultation to the final work provided, a high level of professionalism was maintained. The work was provided on time and on budget. The half-decade-old rat’s nest of plumbing we had in our basement is now a beautiful, clean and efficient setup and has no doubt added value to our home. I would highly recommend A&S Nathan for any work needed."

- Dave K in Newtown, CT


Impressed By the Quality of Their Work

"I recently had the pleasure of having A&S Heating and Cooling install central air-conditioning in my home in Shelton. I was impressed by the quality of their work. The men worked within the time frame they promised. They began when they said they would and finished ahead of schedule. They were extremely neat and organized. There were some days I would come home and I would never have known they were there if I didn’t see the new vents in my ceilings. During the initial meeting, I was advised about my options and I was given the opportunity to ask questions. Allen Nathan, the owner of A&S Heating and Cooling helped me choose the right system for my home, had it installed quickly and efficiently, and I would recommend him and his team highly to anyone looking for work done in their home."

- Kimberly T. in Shelton, CT

A Beautiful Thing!

"Thanks to you and to Mike for working my circulator replacement into your busy season yesterday. Mike told me that he's been working into the late evenings, so I really appreciate it. I'm running heat this morning, and it's wonderfully silent, no impending explosions :) A beautiful thing!"
