HVAC reviews across the US

The quality of his work was top-notch, and I can already feel the difference in comfort and energy efficiency. It’s clear that he takes pride in his craft and has years of experience under his belt.

I highly recommend him to anyone looking for HVAC services. If you want expert-level service with a friendly, customer-first approach, this is the guy to call! Again Thanks for putting my Mini Splits in!

Will from Air Pro Hvac installed a mini-split on my home, he was professional, honest and an expert in his trade! Thanks! I'll definitely hire Air Pro Hvac again!

I hired Air Pro to install mini splits in my home and they were amazing! Explained the whole process, discussed different options, and gave recommendations on sizing to make sure all aspects of the house would benefit from the mini splits. Super knowledgeable, time efficient, honest pricing and even called to check in a few days after install to make sure we were still happy. I would recommend them any day! Their team worked so well together, they have a great system set up to get the job done quick and right. Bonus points for keeping my house spotless during and after the whole install.

We had a whole mini split system put in about five years ago, and we are very happy with it. The installation experience went very smoothly and I would definitely hire them again. Thanks team

First time using patriot didn't go well. The issue was diagnosing the problem because it was intermittent. But in the end patriot fixed the problem and made it right. Since then the have installed a new gas furnace for my son and a new oil furnace for my neighbor. There price is fair, they come when they say, and the installation is quick and professional. great bunch of guys to work with.

I have been using Patriot since we moved here 10 years ago. They are professional, incredibly knowledgeable and are experts in their field.
I highly recommend them for all your heating and cooling needs!!

They came out in a timely manner was incredibly professional went through what the problem was and their approach on fixing it. I asked if I needed a new furnace and they said no . What a great company Total honesty.

Last year I had my wells McClain gas boiler
yearly Serviced, upon that inspection , they checked on my water tank. which was old and he recommend me to maybe think about getting a new hot water tank, It was starting to go.. I Knew it was getting old and
taking long to get hot water, they Came back in a few weeks and put in a new new hot water tank. I am giving them a call this year, for yearly service on my gas boiler very reliable and great knowledge company

Patriot Heating & Cooling did our annual boiler service and did a great job. Professional, efficient, and fairly priced. Everything was handled smoothly, and I’d definitely recommend them for heating and cooling service.

We called for an emergency NO HEAT..Our Oil furnace had an issue. Patriot Heating, answered our call and sent a technician out in the same day. Justin was knowledgeable, professional and caring. He got us up and running and we are now NEW Patriot customers. THANK YOU!

Very recently (Tuesday) I had my heating system replaced. It was planned, so it wasn't an emergency situation; but it was imminent. In any case, I called Patriot Heating & Cooling (out of Candia), and met with someone (Whit) to discuss the best options based on the confines of my space. He came up with a proposal, and I decided to move forward to have a new boiler installed. We scheduled the installation for this past Tuesday.
Two technicians showed up promptly, (the owner even came out, just to check things out), and Whit showed up briefly as well.

These technicians went about their work efficiently, and they did their very best to be as non-disruptive as possible. The technicians (Collin and Jonathan) were friendly, extremely respectful, focused on their work, and prepared. As it turned out, the job took longer than originally thought (due to structural constraints), but they were committed to getting it done and they did. As late as it was, they were very conscientious about clean-up. I couldn't have asked for nicer people to work with.

I highly recommend Patriot Heating & Cooling. I feel secure in knowing that I have a company to turn to if ever I need to (and I'm sure that I will for yearly inspections).

Andre and his team are fantastic. He’s helped me solve multiple problems on two separate occasions including fixing our ac when it wasn’t working in the summer and more recently a larger project involving moving furnace exhaust pipes and relocating a condenser. Professional, excellent communication, and great results with everything he’s done for us. I wouldn’t hesitate to call him back for anything we’d need in the future. Great guy, great team, awesome service!

Andre did a great job setting us up with 2 new Mitsubishi heads. Him and his crew are professional, thorough, and got the job done quickly. He went above and beyond with answering other questions unrelated to the scope and I really appreciated his expertise. We were referred to Andre by a friend, and I would recommend him to anyone in need of HVAC services. We will be reaching out to him for any future projects.

4 days before Christmas and 3 days before an arctic front was to hit us, our furnace decided to die. Andre from Nadeau Mechanical immediately responded to our call and gave us a quote that was fair and more than competitive. Within 24 hours of the quote, Andre came back and installed our furnace. He then followed up with us to make sure that everything was running smoothly. We were so impressed that we decided to have him install a central AC unit which he completed one week later. We would definitely recommend him to anyone and will certainly use him again! It's also nice to support local business!

Andre and his team installed a full ducted HVAC system start to finish in our old farmhouse remodel and did a fantastic job. He was a wizard with the duct work and executed flawlessly given the challenging situation and space constraints. Quotes and pricing were super fair, gave us easy to understand good/better/best pricing - he even continues to check in to make sure the system is working as intended. Cant recommend him enough!

I’m writing to very strongly recommend Nadeau Mechanical and its owner, Andre. This is based on the work they recently did in updating our 25-year-old HVAC system. Andre was originally recommended to me word-of-mouth by the head of a well-regarded contracting company that does a good deal of restoration (our home dates from the mid-1800s). His description included things like “smart, energetic, easy to communicate with, does good work”. That’s been completely confirmed by my recent experience with Nadeau in replacing two aged A/C condensing units with heat pumps, removing and replacing the two corresponding air handlers, and adding controls to make these play nicely with a new natural gas boiler being installed as backup. The price was quite competitive compared with the other quotes we initially got. It struck a good balance between replacing worn out mechanicals and keeping newer ones that didn’t need to go. Installation quality appears to me excellent. Nadeau managed both technical issues and an extensive bag of unanticipated new local permitting rules without the project falling behind in schedule. While they are based in NH, they do a fair amount of work much nearer Boston and this has proved in no way a problem. Overall, a very positive experience.

Nadeau Mechanical is well represented by Andre and Joe. We contracted for an extensive HVAC for a basement using the existing main floor system. The estimate was detailed and a date set.
Andre and Joe arrived on time with all the required duct components and new thermostats. The project was completed in four days without any issues.
Excellent work at a fair, negotiated price.
Highly recommended.

I was referred to Nadeau Mechanical by a friend. Andre, the owner, is incredibly knowledgeable about HVAC. I put an addition on my house and wanted to upgrade my old oil burner system to a gas forced hot air heat/ac system. I had a local company come by and they said that it wasn’t possible to run new duct work to the second floor because of the open concept cathedral ceiling design. Andre came out and took a look and said he could do it. Him and his crew are true professionals. They did an amazing job and we couldn’t be happier.

Andre was excellent all the way around. Contractors who answer the phone and show up promptly means a lot these days. I highly recommend Nadeau Mechanical for your projects!
Andre did some gas supply line changes. I needed two boilers disconnected. And the HW tank reconnected. His pricing was very reasonable. Boiler pictures to show what needs to go away. The 2 pipe steam system is prehistoric.

Wonderful company, so glad we chose them to install our propane gas fireplace insert. It looks great, is easy to use, and creates such a warm and cozy ambiance. They are awesome to work with across the board from scheduling to servicing. Chris especially has been super helpful and very patient too!

My experience with CEASER Chimney was outstanding. I found them to be prompt, professional and honest. A couple items on the estimate turned out to be overstated. They provided that information to me and reduce the final invoice. There is a culture of customer friendly interaction from all of their technicians. This is not a small mom and pop operation, but you do get that kind of vibe from all the staff, including those in the office. Highly recommended !
