Thermoil is excellent. They are my go to technician for plumbing, heating and oil services. 100% reliable. They’re always available. I don’t get others anymore. They attended to my heating problems even late at night.

We have used Thermoil services many times, including plumbing work, water heater installation and ductless cooling and heating for our first home. When we moved to iur new home, they delivered oil on a schedule based on our consumption. And recently, Thermoil installed heat pump for our second floor and ductless heating/cooling for our first floor. They are fair, punctual and professional. We recommended them to friends and family and will absolutely use their services. They pickup the phone when we need them the most and take care of our family like their own.

It was a disaster. They held up our project for weeks preventing us from moving home. When we finally moved home, two of the tubs they installed leaked and caused hundreds of dollars in water damage. After the boiler was purchased, they would not show up to install it. I had to threaten them to get them to show up and install it.
Description of Work: My husband and I hired a general contractor to renovate our home. The general contractor hired Thermoil for our plumbing. I hired them to install a new boiler.

He came out this afternoon, took one look at the furnace and said there’s nothing wrong with this furnace. You don’t need a new one. He fixed it in fifteen minutes. It just needed the water valve adjusted. Of course, this should have been seen and fixed by my service company whose only interest, apparently, was to sell me a new furnace rather than fulfilling their service contract. Angelo saved me thousands of dollars. He was fabulous. I have not yet received his bill but I will happily pay it. Great to get an honest person.
Description of Work: The company which services my furnace came out late yesterday and said there was a problem with my furnace and that I needed a new furnace which they offered to sell me at an outrageous price. They said they could not even turn it on and left my tenants to freeze overnight I called around first thing this morning for quotes on a new furnace and found Angelo at Thermoil who agreed to come out even though he was incredibly busy on one of the coldest day of the year because I told him there was no heat.

It went very poorly, and I advise you to find another provider, there are many good ones out there.
Description of Work: Thermoil installed the HVAC system and combo-boiler in my house. Even though this is their stated expertise, items were installed improperly and had to be repaired or replaced. Technicians were late, or didn't show up, and were reluctant to remove or cover their boots to enter the house during a rain storm. I took a video of a technician arriving to my home late, and instead of coming inside, he laid down to rest/nap in his van.

Thermoil come out and filled the freon (again). They also did a leaked test and confirmed the worst case scenario (leak is in the coil). The tech was professional, explained everything throughly. They were slightly late as the previous scheduled technician had an emergency, but they called and informed us ahead time and sent a second technician about an hour later.
Description of Work: Needed to have my Central A/C checked up and do a leak test as I presumed there was a leak.

Smooth. However, we had to wait a little bit since they get busy from time to time.
Description of Work: We have used them for a number of different projects. They are thorough and professional. They finish on budget. And are experts in heating/cooling and plumbing. They are great for maintenance services as well. We use them to maintain heater and deliver oil.

They were very professional, responsible, punctual, it's a great company to do business with. Their excellent. They can do everything, working on hot water heater, their doing plumbing, their doing gas lines and if you got people doing that kind of work for you, you want to make sure you got people that know what they are doing, a lot of time it emergency work when the heat goes out, you lose water pressure they get right out there.
Description of Work: I used Thermoil for heating and a/c service.The furnace was replaced, I have them do all of our maintenance and emergency repair work done on my commercial buildings and also in my home they repair the furnace hot water heaters over the years yeah they done a lot of work for me. They come an service the furnaces and boilers in my buildings and in my home.

But besides having great guys on his crew (Robson and Francisco), the work was performed all in one day and they cleaned up after themselves very neatly. On top of it all, I had a huge box delivered but had thrown out my back, so I asked if they could help move it into the garage--and they moved the whole thing themselves for me. Just very classy, nice folks. And good at what they do.
Description of Work: We were referred to Thermoil by someone who owns properties and has them do her plumbing for her tenants. Angelo replaced our furnace with a new one (rated 80%) for the best price out of four estimates we got for comparison. They removed the old furnace and had it junked, also installed a new exhaust pipe, and of course connected everything up and tested it, then cleaned up.

I first started using Thermoil 3 years ago after meeting the owner, Angelo, who impressed me with his knowledge, his background, his responsiveness, and his business sense. I first contracted them to service my oil burner and deliver my oil. I was amazed at the savings that I made by switching to Thermoil as compared to the previous supplier. A year later, I contracted them to service my central AC unit and to also install two ductless AC units for my basement and a separate office. That went very well also and I was very pleased with their work. Now, Thermoil handles all my AC work as well as my oil and the plumbing around the house. As a result, I have accomplished significant savings and the work is excellent. I recommend Thermoil with no reservations. they are a very reliable and honest company.

They are very reliable and come right away whenever we call them. They come whenever the tank is about three quarters empty. They are professional and really good. They are reasonably priced too.
