Airco's tagline is "Repairing Low Bidders Work, One Day At a Time," which sets you up to expect a premium — then a customer replacing a furnace in December 2024 said Joe worked through their goals and options before writing a quote that was the best price they had seen by several thousand dollars, and a May 2017 reviewer says their quote came in lower than other companies. Airco Home Comfort Services is a Watertown HVAC contractor working across Middlesex County: heat pumps, furnaces, air conditioning and tankless water heaters. The company says it has been at this since 1997, and its BBB page has been accredited since 2004 and carries an A+ grade. Two names run through thirteen years of reviews. Joe is named in thirteen of them, back to a January 2013 review of a detailed, accurate quote; he is the one customers describe laying out the options — clear choices and prompt answers on a heat pump in February 2026, a more thorough evaluation of the house than other installers before selecting equipment in June 2013. Steve turns up in seven, running installs. An April 2026 customer called the install super clean and noted Airco came back once to replace a failed capacitor in the compressor. The rebate paperwork is its own selling point. A February 2024 customer had a central air heat pump and tankless water heater put in through Mass Save and says the owner helped file the rebate; an April 2015 review credits Airco with a zero-interest Mass Save loan for a heat pump; a May 2024 customer lists rebate paperwork alongside the sales and installation. The systems range from a geothermal heat pump replacing an oil furnace in a December 2023 review, to a Fujitsu unit for a tenants' third-floor apartment in January 2024, to heat pumps and mini-splits in a condo in February 2026 that the owner says came in on time and on budget. Three things to raise before signing. In a January 2024 review, a landlord waited six months in the queue while Airco held the deposit — a 2022 customer says Joe was upfront about that wait. A February 2024 reviewer says the company refused to close permits in a timely manner and that, after a sale and installation they were pleased with, they could not get a reliable reply to texts or calls for repair. And in April 2026, a homeowner gave three stars over a heating and cooling pump system installed in late 2023 that gave them trouble quickly, while still calling Joe helpful. For a heat-pump conversion, a furnace or AC replacement, or anything running through Mass Save around Watertown, Airco is a strong call. Ask where you sit in the installation queue and what the deposit holds, and get permit close-out and post-install service spelled out in the contract.
“Joe had been working with Sears for over a decade, managing their window business in Texas and roofing in New England when he transferred into the HVAC division. Steve at Airco was one of his top installers.”
I recently hired Airco Home Comfort Services to upgrade several major systems in my home, including two new furnaces, two AC units, an on‑demand tankless hot water heater, and whole‑house water filters. I couldn’t be happier with the results. Airco completed all the work in a timely, professional manner, and their pricing was excellent. Each system has exceeded my expectations in both performance and efficiency, and the upgrades have truly transformed the comfort and quality of my living space. I highly recommend Airco Home Comfort Services and will absolutely use them again if needed in the future.
Airco (Steve) installed HVAC throughout my home. Answered all of my questions and addressed any concerns that I had. Professional install, timely and his price was competitive. Install was super clean and has been out once to replace a failed capacitor in the compressor.
Quick response, great service. They were able to get my system up and running timely and affordably. I recommend them highly.
Airco Home Comfort Services was great to work with. They were on time, professional, and really knew what they were doing. They made the whole process smooth, answered my questions clearly, and did quality work. You can tell they care about their customers and take pride in what they do. Definitely recommend Airco to anyone looking for reliable HVAC service.
We used AirCo for a pump system for heating and cooling back in late 2023 when we moved into our home. While we found Joe helpful with many things, we had issues with the system pretty quickly. A central system was installed upstairs with a Daikin one thermostat. In heat mode the thermostat never heats at the temperature set, it always overshoots by at least 5 degrees in some cases up to 10 degrees. This is really inconvenient. They never had answers or solutions for this and had attitudes when we tried to get them to come back and repair the issue. We finally gave up asking and the 1 year warranty expired. The AC works well enough, though also doesn't have an accurate temperature read, and we use it sparingly. Overall we were left unsatisfied customers which was a shame because we did a lot of research, were excited about the installation, and using the company.
