Best Heating & Air Conditioning / HVAC In Nashua

“Brad arrived on time, was professional & courteous. Joyce continues to dispatch good people to keep my HVAC humming along!“

“I can't say enough great things about this company and serviceperson Jim. Courteous prompt service. Quick responses. I am a new resident in this state and had no prior connection to any heating service here. Not only was each employee I spoke with wonderful but they helped me quickly and efficiently. I am now a customer forever.“

“Every once in a while, you come across a company that communicates clearly and honestly—no gimmicks, no sales pitch. This is that company!
I did my homework, bringing in a few other companies for quotes on a complete furnace and air conditioning package. Let’s just say I learned a lot in the process. Unlike the others who tried to “sell” me, the owner of this company assessed the situation, provided a straightforward, all-inclusive quote (which was lower than the rest), and earned my trust.
After the installation, I was amazed at the amount of work involved—far more than I had anticipated. Yet, everything was done meticulously, with top-of-the-line equipment and first-class workmanship. The all-inclusive quote, truly covered everything.
I highly recommend working with this company. They deliver exactly what they promise—no surprises, just quality service.“

“Brian and his crew were an absolute pleasure to work with. They're very responsive, and show up when you need them! Brian solved all our plumbing needs for a new addition and gave us a very reasonable price. I highly recommend Brian and his crew for plumbing needs around Nashua!“

“Brought in an old inducer fan from an old Amana furnace that I couldn't get the model off of. They were extremely helpful and they were able to get the new part number and even had it in stock. Great price and was back with heat in no time.“

“I am remodeling and doing upgrades to my childhood home and it was time to replace the 40 year old natural gas boiler and 25+ year old hot water tank. Back when the boiler was installed it only had a efficiency of 67%+-. As you can imagine after working hard in all these New Hampshire Winters throughout the years I'm sure the efficiency has dropped dramatically(as I could tell by my energy bills). I knew I was on borrowed time with both these units and figured lets get this done during the Summer before the worst would happen during the Winter. As most people in Southern NH knows MASI's has been here for a long time(over 60 years)and is a family run business. Being a business owner myself I know that customer service is a key part to business. Anyone can sell you product, but it's the service and focus on detail that makes a difference. When I fist called and spoke with Keith he was extremely knowledgable and helpful with what my heating/hot water needs would entail. He then came to my house to access those needs and made some recommendations. We both agreed a combi unit (both heat & hot water)would be the best efficient & economic way to go. We went over the different models and I decided on the Bosch Singular Combi Boiler. A bit more expensive than others but I am very familiar with the Bosch family of products and have many in my home. Including all Thermdor kitchen appliances which is part of the Bosch family. Keith also took care of the town permit I needed and filled out my EngeryStar rebate to submit. The installation went smoothly. Julio, Kayden & Dave worked seamlessly to get everything in stalled correctly. All the copper piping was connected with the industries best fittings, Viega press fittings. This is the latest in technology to pipe fitting. No Soldering required. Less mess and no flames.
Another nice feature to this system is there is nothing on the floor of my basement. Everything is attached to the wall. The whole installation process took 2 days work. I really didn't realize all that was entailed to this installation. A lot of work for these 3 men. All 3 men where extremely polite and were more than happy to answer any questions I had. After my new combi boiler was installed they also replaced one of my outdoor water spigots which was corroded and had stopped functioning.

When all was done everything was clean & tidy. The only way I knew they were in my home is I had all new equipment.

I can't tell you how satisfied I am with MASI Plumbing & Heating.
It's nice to know we have reputable company in our backyard.“
