HVAC reviews across the US

Very pleasent people too be around

always responsive and great customer service. We highly recommend👍

Got a price from Dan which was very reasonable two weeks later Eric and Nick came over installed everything and it looks great couldn't be any happier and cleaned up nicely

"Everything about my experience with Danerik Mechanical was great! They arrived at my home on time. The work was done exactly as promised and done well. I found it helpful that Erik took the time to walk me around and show me the work that had been completed. I also appreciated Dan's timeliness in responding to my communications. The entire team, including Nick, were friendly, knowledgeable and professional. Thanks so much!"

Danerik Mechanical has done a number of jobs for my husband and I. They always do a fantastic job! From redoing our entire HVAC to all new plumbing for our bathrooms and kitchen. Very happy with the work they do and happy to recommend them to anyone in need of their services.

All questions were kindly answered, the work was done in a timely manner to suit my needs. The equipment installed works beautifully. I highly recommend this company.

No hesitation in giving Danerik Mechanical a glowing 10 out of 10 recommendation. Great folks to work with. Dilligent, professional and courteous.

I've been using Danerik for a little over a year after a suggestion from some neighbors. I used them on my new home which has a gas-fired on-demand hot ware heater I've never had before. They recommended some simple items to keep the system running properly which I did not hesitate to have them do. I've found them to be honest, on-time and all the work has been within estimate. I highly recommend them for your mechanical needs

Once again, Danerik did a great job for us, this time installing purge valves in the heating circuit for our indirectly-heated Viessmann 300-V domestic hot water tank. This allowed them to purge and replace the water in the heating coil for preventative maintenance. (These valves were omitted by the original contractor who installed the system.) We're happy customers, again.

⭐️⭐️⭐️⭐️⭐️

I honestly could not be happier with the entire experience working with Danerik Mechanical LLC.

From the very first visit to the final day of installation, the entire team was professional, knowledgeable, transparent, and incredibly detail-oriented. You can immediately tell they truly care about the quality of their work and about doing the job the right way — not the fast way.

They took the time to thoroughly assess our home, existing HVAC setup, and heating/cooling needs, and recommended a system configuration that made perfect sense for our house and budget. There was never any pressure or overselling — just honest guidance and expert recommendations.

The workmanship throughout the installation has been outstanding. Everything was installed cleanly, professionally, and with great attention to detail. They were extremely organized, respectful of our home, and always willing to answer every question we had along the way.

What also really stood out was how helpful they were with rebates and incentive programs. They guided us through everything and made the process easy and stress-free.

It is rare these days to find a contractor that combines:
- professionalism
- technical expertise
- honesty
- communication
- friendliness
- and true pride in workmanship

Danerik Mechanical delivered on all of it.

I would recommend them without hesitation to anyone looking for HVAC, heating, cooling, heat pump, or furnace work in New Hampshire.

Absolutely top-notch company and team. Thank you ag

Great service. Had a unique maple operation boiler tune up. They were awesome. Great communication and the tech explained the process which I appreciated. Highly recommend.

Jerry Perry, owner of Patriot Oil Burner Service, provided us with fast, reliable, quality, affordable and trustworthy service, during a stressful time with a frozen pipe situation. He also referred other professionals that were needed as well. Multiple resources referred me to Patriot Oil Burner Service. We are grateful.

Jerry was great! Had taken great care and time to explain our options and the terminology behind all of what he was saying. Great customer service and installation! Would definitely recommend him!

Patriots Oil Burner Service was referred to us by an associate of theirs. The service tech was friendly, knowledgeable and took the time to explain what he did and why. When he found an issue with our burner he explained the problem, why it happened and was prepared to fix it on the same day. We were very pleased with his service and plan on making this company our new go to.

I am so impressed with the outstanding exceptional service we received from Patriot Oil Burner Service during this last snow storm. I live on a private dirt road that requires 4 wheel drive during a big snow storm. The road was not plowed yet. The heating was not working on the second floor. Jerry walked my son through the steps to try to fix the problem. He came to the house early the next morning to access and fix the problem.
I can only say that Patriot’s service is
impressive and the response was fast. Jerry was professional, friendly and helpful with explaining the issue. I recommend Patriot Oil Burner Service. Thank you for your great service.

Really happy with the service from Patriot Oil. I called with an issue on my oil burner and they were able to come out within a couple of hours. They diagnosed the problem and replaced the controller quickly. Jerry was friendly, professional, and explained everything clearly. Great experience overall and I’d definitely recommend them.

Jerry and crew updated my 28 year old boiler and did a great job. The install looks great, they cleaned up and hauled the old stuff away. Their price was fair and communication was great.

Excellent job! Gerry and Xander very knowledgeable and pleasant to work with. Super efficient work ethic, job done in a timely manner and they clean up after job is done. Would highly recommend Patriot Oil. Very pleased

These guys are awesome! Very fair price, and great work. I would encourage anyone to give them a call.

Ryan and Joey are top notch professionals. They’re on time and reasonably priced for the quality of their work. I highly recommend reaching out to JR Mechanical for any of your HVAC needs!

Joey has gone above and beyond for us! He has ensured our mini split units function properly and did an excellent job with installation and follow up! Thank you Joey for your great work!
