The Gas Connection LLC

I have used the Gas Connection for over 10 years now. They are an amazing company to work with. Jason and Dave are among the best in the business, and have saved me in more than one heating/cooling emergency. Their pricing is reasonable, and they absolutely stand behind their work. Cant recommend them highly enough!

Update on 7/24/2020: Once again, cannot tell you how impressed I am with this company! My 20 year old furnace was showing signs of aging, and needed to be replaced. Dave went over the options with me - what has always stood out to me is their absolute honesty. No high pressure sales, and they even recommended that I could keep running some of my older HVAC components for a few more years. His crew of Tim and Trevor did a phenomenal job of replacing the old furnace and left the area cleaner than it had been when they walked in :-). Keep up the amazing work, and know that you have a customer for life here!

I recently had my furnace replaced and added central air conditioning to my home. The Gas Connection was awesome! The owner Dave came out and gave me a full rundown on options and a complete picture of the costs. The crew came out within a week and completed the install in 2 days. The did a great professional job. I started using the Gas Connection about 15 years ago and have been very happy with them. I used other big name companies in the past and always felt like I was getting hosed. Not with these guys.

Gas Connection is absolutely the most responsive, professional, reliable, accommodating, and trustworthy company that I have ever dealt with!

I was in the process of selling my home and, based on a home inspection, needed to have my furnace replaced. The day after coming in to assess my situation, they had my new furnace in place! Everyone that I dealt with at Gas Connection, from Tracy, to the owner (Dave), to the installers, Tim and Trevor, was so professional, knowledgeable, helpful, and extremely kind! They all went out of their way to help me out during this process!

I highly recommend this company and will be telling everyone I know about what a positive experience I had with them. They made the not so pleasant experience of replacing my furnace, into a very pleasant and positive one!

Please make them your first call if you ever need an HVAC contractor!

Wonderful to know I have a HVAC team I can trust to support our home. They keep everything running so smoothly. Provide very reasonable options when you need to adapt or fix an issue. I would highly recommend the professionals at The Gas Connection for all your heating and air conditioning needs. They’ll have your back when you need them most.

I would like to compliment Tim and Trevor on the top rate service I received when Gas Connection replaced my heating system. Their work is unparalleled. I appreciate the superior customer service. You can be sure that I will continue to do business with Gas Connection for years to come. I definitely will recommend Gas Connection to anyone looking for the best, trustworthy and honest co. Don’t waste time calling around, just call GAS CONNECTION.

Hands down the best HVAC company to work with in Nashua. We had a new top of the line Trane heater and A/C installed, couldn’t be happier! From start to finish, they exceeded my expectations and when they were done, they cleaned up so well, you couldn’t tell they were there! Our house finally stays nice and warm, can’t wait to try out the new air conditioner! True professionals, they earned my business from here on out.

Absolutely a pleasure dealing with this company. I have been using the Gas Connection for over 10 years now, and they have always been prompt, professional and great to deal with. On more than one occasion they have stopped by at a moment's notice to fix an errant HVAC system in the middle of winter. Dave (the owner) and Jason always take great care in diagnosing the issue and giving you the most effective solution. They never try and push unnecessary maintenance on you. Keep it up, guys, and I wish all contractors were like you!

Gas boiler was in middle of being repaired by another service provider, who stiffed me, and it was December. Called the Gas Connection, not only did they take on the job, they assisted in every detail including financing. They even provided portable heaters until job was complete. Efficient, moved schedule around, helpful, provided suggestions for future care of new boiler etc. GREAT COMPANY!

I was able to receive a quote to replace my dead AC within hours of calling. The quote was fair, the scheduling quite quick and the installation very courteous and professional. I will certainly be calling for any of my future HVAC needs and definitely recommend to others!

When your hot water tank goes and your basement is full of water, it stinks!! The Gas Connection called me back right away and said they could come over the same day. Probably late afternoon...which I get because they are busy! Then at about 1:00, they call to say they can be there in about 20 minutes if that is ok.
OK???? AWESOME!!! The came, were professional, way earlier than planned and did a fast, professional job. I was in a hot shower shortly thereafter. No hassles, just great prompt service from guys that have been in the business for decades. USE THEM. You will be glad you did!!
