Lisa franci

I just had my furnace, hot water heater and A/C replaced. I was nervous to make a decision on which company to trust for such large purchases and work. From start to finish, I felt the most comfortable with Mike the salesperson and then the team who did the work today. They were all efficient, gave clear explanations about the work they did and extremely courteous. I’m relieved that the experience was such a positive one. I feel I received high quality work with very skilled technicians at a very fair price. Thank you so much and I will be happy to ever be a reference for you.

Elizabeth MacDonald

Snow was blocking an exhaust vent outside on Sunday night/early Monday. My furnace shut off. I called this HVAC company, who did work here about 5 years ago. A super professional man came through bad streets and tons of snow and fixed the issue within hours of my call. Great customer service. I highly recommend this company!

Andrew Z.

Used them for AC install, great pricing and quality. Also contacted them for furnace issues with producing enough heat and cycling too often. Instead of a service call they suggested I inspect my HVAC filter, they informed me that some furnaces have issues with high efficiency filters (MERV 13). After I put the old filter back in all functioning as designed. Highly recommend Gustafson HVAC.

Paula Lindse

First rate quality service, fair and reasonable pricing, very professional. We had received 3 other bids and Gustafson was by far the most reasonable and responsive team. Mike supervised the team the whole time. Group of install guys were fantastic. Cleaned up everything, walked me thru operations of new furnace and air conditioner. Arrived on time, installed both furnace and air conditioning unit in about 6hrs. A+ recommendation and will have our business in the years to come.

Mike Grippe

Highly recommend Gustafson. Mike came out and provided a detailed estimate and scope of work. Their crew showed up on time and they were very careful to not to make a mess. Tarps were put down to ensure everything was kept clean. Install went great, and I couldn’t be more pleased with the workmanship. You can’t go wrong doing business with Gustafson!

Jody McGuirk

I cannot recommend this HVAC company enough. They responded promptly to my initial request. Answered all my questions throughout the process. Had the most reasonably priced options out of three companies we called for estimates, as well as provided more service for that reasonable price. They were on time for installation, did a great job of installing and keeping the area clean. We had new furnace and AC system installed. On top of it-the new system works great and is quite. We are very happy!

Sean Tynes

They were scheduled to come out in 5 days to fix the AC in our new house we had just moved into. My mother in law that lives with us is going through chemo and the heat was making it even more difficult for her. They came out the next morning and fixed our issue. The technician was really nice and sincere. I would recommend them to anyone

Pierre Gutierrez

Robert Gomez performs the highest quality job that I have ever received for HVAC. I’m extremely pleased with the service and will be using Gustafson going forward. Robert is extremely knowledgeable and is detail oriented. Absolutely 5 star as he goes above and beyond. Highly recommended for quality service. Thanks!

Krista Bunten

I had the whole HVAC system installed by Gustafson about three years ago and recently requested maintenance on the system. Technician Robert Gomez was the tech that responded and he was very personable, easy to talk to, and explained what he was doing to me to service my furnace. I felt like I received thorough service and he provided advice for the future as well. Thank you, Robert!! I hope to be able to request you again in the future to do maintenance on my AC next spring.

Nancy S

We had a new a/c and furnace installed this spring by Gustafson. They were able to come and give us an estimate within a couple days. We got scheduled for the install within a week. They were on time the day of the appointment and made sure everything was done perfectly and there was no mess. When they were here to do the install, we decided to have the hot water heater replaced. They noticed that the main shut off for the water was leaking in the crawlspace, so had them do that too. They got that done the following day. The price was a lot less than the other estimates obtained. They are an approved vendor with Excel and they completed all the paperwork for the rebate. Happy we went with them and no regrets. Highly recommend them.
