Best Heating & Air Conditioning / HVAC In Tyngsborough

“Highly Recommended!!! The level of Professionalism & Integrity of this company is astounding. A Fagundes did a complete Re-Install of my Dual Zone, Heat Pump, Integration with my Viessman Boiler (Back up for extreme Cold), and brand new air handlers. The technicians that showed up were Polite, Courteous, Punctual, Communicative, and best of all Really Good at their Craft! This was a big job and it took 2 1/2 days to get it done. I could not be happier with their work! to make it even better.... the Owner followed up with my multiple times during the project to make sure things were going well.“

“EarthTech designed and installed a groundwater heat pump system in our 2400 square foot home. We already had a MassSave approved insulation and weatherization upgrade completed, which was necessary to install the groundwater heat pump. EarthTech was professional and pleasant to work with at all times. The installation is professional and neat. The project came in on budget with no surprises. EarthTech also helped us with the paperwork needed to obtain a MassSave rebate. We are very pleased with how the system is working. It has kept us warm in a chilly May and cool in a hot June. We are optimistic about how the system will perform during the next winter.“

“I own a small business in Tyngsboro. I had a water leak that needed repair. I called Koval Plumbing to ask for some help. George called back the same day and showed up before I closed. The problem was fixed quickly and at what I consider a very fair price. He told me what I need to do next and when I'm ready I will certainly call Koval to do the new install. Thanks George and thanks to your brother too!“
