Heating & Air Conditioning / HVAC near Londonderry

“We worked with Chuck and Andrew on an Accessory Dwelling project. They helped make a pretty complicated project much easier- we had a bunch of plumbing, hvac, and electrical work that needed to happen, and they made it very easy for us. They're true professionals- they price fairly, communicate very well, and they're very organized.

These guys would be my 1st choice for anything big or small that I have in the future!“

“John is always very responsive and reliable. He has bailed my commerical kitchen out of more than a few jams this past year with dependable, quality work.
He really does understand his trade and im happy to recommend his work to anyone in need. If you want the repair done correctly the first time with a fair price Temperature By Design is the way to go.“

“This guy is great, calls back, is responsive and is very technical, he knows modern HVAC heat pump systems thoroughly.

The original dealer that sold me my equipment in six years has never once returned a call, even for annual service, not a great feeling. Highly recommend Zibby.“

“I came into the trades because I wanted meaningful work, and this place delivers. The culture is safety-first and do-it-right, not “hurry up and hope.” My truck is stocked, the support line actually answers, and if a job needs extra time to be done properly, management backs the techs. That matters.

What I love most is how we treat customers -show up when we say we will, keep the work area clean, explain what we’re doing, and leave things better than we found them. Winter gets busy (no surprise), but the team pulls together and nobody’s asked to cut corners. Training and mentorship are real, not just buzzwords.

If you’re a customer: you’ll get honest recommendations and solid work.
If you’re a tech thinking about applying: expect good people, clear procedures, and a company that lets you take pride in your craft. Couldn’t ask for more.“

“We got home this evening to a very cool 50° home. Made a call to Absco and they got here in record timing. The first words I said to the kind gentleman Levi were, “Wow you got here super fast”. I showed him to the basement and he took it from there. Very knowledgeable and knew what the problem was in seconds. Got everything up and running in no time. After Levi left another problem arose. Called Absco back and yet again, awesome service all around. Levi showed back up and thanks to him, we are now comfortable in a nice heated home. Thank you Levi for your hard work and incredible timing, as well as the kind individual(I believe her name was Debby) I spoke with on the phone. Great service all around, 10/10 would recommend!“

“Ken has helped me out on a number of occasions; even on weekends when plumbing emergencies love to happen. He’s great at what he does and very responsive. Thank you!“

“Jolt Electric could not have been more accommodating. They had a cancellation and called me to perform a preventative maintenance on my AC unit. I neglected my unit so it needed some cleaning and attention. They did a great job and educated me along the way! Would highly recommend their services!!!“

“Erik is as good as it gets for timely service and advice at a reasonable cost!

Erik and staff have been servicing my home AC units for the last 10 years, and at my local business where it's critical that customers are comfortable he is always there very promptly as I have needed him. I appreciate him making time in his schedule and very fast turnaround!“

“Jason was professional and thorough with the work at my house. I would absolutely recommend Conerstone for clean quality work. I had 21 vents cleaned.“

“The tech, A. Gauthier, was attentive, knowledgeable, and thorough. He asked a lot of questions about past issues, and gave a few different ways to fix the problem. Highly recommend.“

“We’ve used Jason for multiple jobs and he is excellent. Responds timely, very reliable and easy to work with. He caught something that another company did that was not up to code and helped me navigate the situation! We will continue to use Jason for our plumbing needs. 10/10 would recommend.“

“If 10 stars were available, I'd rate Masi there. Mr. Masi and Keith were amazing! Incredibly knowledgeable, helpful and flexible. This team went above and beyond to meet my niche plumbing needs and I'm so grateful for their help.“

“We’ve had Brady Home Services do multiple projects in our home, from installing a water softener system, to overhauling a bathroom. The team is always professional and friendly. Plus they’re great at providing options and explaining what they’re doing and why.

We highly recommend them.“

“Bill Trombly Plumbing was able to service my boiler several days earlier than planned due to an opening in their schedule. Chris was knowledgeable and professional. Highly recommended!Service: Heating system repair“

“Fantastic service!! Very professional. Very reasonable price. I plan on using them for annual maintenance and repairs based on their excellent first interaction.“

“Jacob did a great job explaining my situation to me and relaying my story to the service manager at the office. I received my quote quickly and clearly stating the options available to me with clear pricing and available discounts. I was impressed with the quality of work and the efficiency of service. Thank you.“

“My experience with Jeremy was outstanding. I didn’t detect any bs regarding the best solution to replacing our 38 year old system before the heating season. I wasn’t disappointed in the results. On installation day (Wednesday 15 October) Ben and Kaleb showed up on time and completed removal of our existing system and installed the new unit all within 5-1/2 hours. I was very impressed with their professionalism and attention to detail.“

“We had a component fail on an older boiler near the holidays. I got a few quotes from some competitors and then a friend of mine referred me here. Lila and her team helped rearrange schedules and I get the job done in time for us to host and beat out all of the other quotes we received by 30%! Couldn’t recommend them more. Bonus the are locally owned and operated for four generations!“

“Edward arrived promptly on time, was extremely courteous and knowledgeable. He diagnosed my dead a/c quickly and I decided it would be cost-prohibitive to repair and will arrange for a replacement unit instead. Give Edward a pat on the back for doing his job well and being a total professional.

Alex came to my property and installed a fresh air intake vent and replaced an old exhaust vent on my furnace. He was professional, courteous, and very informative in explaining his work. completed the work quickly and everything looks great. He certainly represents Walley's as a top company to use. I will certainly use them for future jobs.

Bryan arrived on time and serviced/inspected my hot air furnace, central air conditioner, and a spit-ductless A/C unit. He was courteous, professional, efficient, and advised me of what he was doing. All work was completed in a timely fashion. Bryan should be commended for his professionalism.“

“The HVAC system replacement with Joyce couldn’t have been better. Our technicians, Benjamin P., Josh Z., Andres C., and Stephen J. were an excellent team, and they worked through the unique issues they encountered with care, installing a new system that operates as well as we’d hoped. They arrived both days at the earliest time expected, and ensured that the house had heat before they left on day one. There were several times during the process that additional support technicians from Joyce came to assist the core team with various tasks , ensuring the most expert results. Benjamin regularly updated us with progress and next steps, and spent time while we set up the Lenox app showing us how to program and manage the thermostat. We would highly recommend Joyce for HVAC work, and are fortunate to have been given a recommendation from our realtor. We will use their annual maintenance program going forward to ensure that our HVAC system continues to function at its best.“

“Michael was very friendly and professional. I would recommend using Heritage to anyone.“
