Gassco Inc

My forced air gas furnace system and AC was installed in 2005. The furnace died and the AC system was end of life so my whole system had to be replaced. I got quotes from greenenergymech.com, dempseyenergy.com, bostonstandardplumbing.com, sila.com and gasscoheatingandcooling.com.

Sila and Boston standard were both crazy expensive. Dempsey was the lowest quote but the equipment wasn't the best and the quote didn't provide much detail. Overall Gassco offered the highest quality equipment at the lowest cost and a clear signal of quality. Green energy would have been my second choice price/equipment.

Gassco were able to start the install three days after I accepted the quote. It took two full days to install with a team of 3. They were punctual, did high quality work, and cleaned up great. I couldn't be happier. The system is so much better than my old one.

I highly recommend Gassco.

Gassco installed a new central AC unit and duct work into our house this summer and the process could not have gone better. Bill came out for an estimate and recommendation for a new unit for us. He is honest and very knowledgable. The Gassco crew came out the following week to take out the old unit and ductwork to install the new unit. They started on time every day, worked efficiently, and were all done in the time we were told. They were very polite and hard working. We used Gassco again in the fall to reinstall/renew some of our faucets and to install a vent into an older bathroom. Again, very reliable and great work! I would highly recommend Gassco.

Bottom of the sink was leaking you were suppose to fix about 6 months ago..It needed a sink basket or something like that. You guys improvised, trying to save a buck, and now all my cabinets are ruined. Not only did you mickey mouse the job you failed to screw it back together using 2 screws instead of the 3 which it needs..You had no problem billing this to a senior, but you also took advantage of her because she didn't know. .I fixed it for her!!!

I received 5 quotes to replace my furnace and central air. Gassco stood out among all the others. Bill, the owner, came out and was the only contractor who took the time to listen to my concerns. He was the only one to do a manual J load calculation and properly size the equipment. (The others all quoted "like for like" equipment despite the fact that my 1997 furnace was oversized). Gassco's proposal/quote also stood out for its clarity in a fair and reasonable price and work to be done.

The Gassco team has great communication and answered all my questions along the way. They are very knowledgable, skilled, and professional. Everything looks great. The high efficiency furnace has made my home much more comfortable and I am looking forward to saving on energy bills as well as a MassSave rebate.

I will be recommending Gassco to everyone; you will not find a better HVAC company!!

Excellent service! My mother used GASSCO for years and they kept our heat pump / air con going through tough winters and hot summers. I recently had them install a new hvac system and was very happy with how easy they made a complex job. Bernie was our most frequent worker and he’s great. Bill was super helpful as well and all the other members of the team. All around polite, efficient and effective. Thank you!

Gassco recently installed a new furnace and duct work. They were prompt with the scheduling and stayed on target with the price. We will use them in the future. Highly recommend.

Gassco installed a heat pump in our attic and a new heating system for the rest of the house. They were on-time, efficient, and informative. I highly recommend using their services.

Gassco Inc are truly the most professional and knowledgeable in what they do. We bought a new house that needed a FULL upgrade of HVAC and water heater as they were old (talking 30 years old on the HVAC). I found Gassco Inc through Mass Save, and after having several companies come out to talk to us about our options it was very clear that Gassco Inc was far and above the others as far as experience and knowledge. We have been extremely happy working with the team especially since I knew next to nothing about HVAC prior to this process. Would highly recommend them to anyone else for plumbing/HVAC needs.

Gassco has been taking care of our air conditioning and heating needs for years and we have been very happy with their professionalism, competence, fabulous employees and the high level of caring about their customers. They really know their stuff and so do their tiff. They thoroughly clean for they re done.

Recently they tackled a very difficult heating issue (that they did NOT create) and after the initial contracted payment they returne numerous times and did not charge for their labor. Our house is over 100 years old land a really challenging but they managed to fix all the problem. Even though we called them many times over this heating problem, their response was consistently kind and they bent over backwards to help us. You will never find a better company for your heating and air conditioning needs.

REPLACED BOTH HVAC AND SPLIT DUCT SYSTEM; INSTALLED WHOLE UNIT WATER FILTRATION SYSTEM
William Gassco (Bill) is an extraordinary manager. He's honest, hard-working, and knowledgeable. His team includes (minimally) a master electrician, plumber, as well as apprentices and journeymen. The entire team seemed to learn from and enjoy the complexities that my home presented. They worked six days, beginning each with the laying down of clean white drop cloths and ending with vacuuming all areas where work had been performed. Every part of this complex and at times difficult job was overseen by a manager. As examples: positioning a large and heavy condenser in a "pit" ten feet below ground level; installing an HVAC unit and water filtration system in a very small space; and running split-duct cable through small spaces and along a deck four stories high.
There is not enough that I can say about GASSCO, Inc. I am normally a highly critical customer who doesn't hold back. With Gassco, Inc. there just wasn't anything to get mad about!!
