HVAC reviews in Williston, Vermont

Highly professional and efficient. Punctual. Excellent communication. I have absolutely no criticisms or complaints. I’ll certainly continue to use the services of the Call the Whale staff. An exceptional company in every way! AND the company sends thank you gifts to its customers! So impressive.

My wife and I just bought a new home in Williston, that was in immediate need of a full replacement on our heating/hot water system. I reached out for numerous quotes, and The Whale was a clear and easy choice.

A technician was available same day to provide a quote the day I first called, and were able to replace the full system within three days of moving forward with our deposit.

Nic & Isaac, who performed the work, were professional and diligent. I had a lot of questions about the new system/investment into my home, which they (& Jennifer + Jordan) were more than willing/able to advise me on.

Overall, we are thrilled with the work done, and despite being a bit pricier than other quotes, you do get what you pay for. Fast, quality work and peace of mind. I trust that if any issues arise in the future that they've got my back.

Can’t speak highly enough of the professionalism and skill set of the technicians. They were timely, great to work with, and knowledgeable.

Only leaving 4 stars and not 5 due to transparency with cost. I unfortunately had damage due to frozen pipes, which required insurance involvement. Given the fact the this company doesn’t itemize any material cost, it made it very challenging to see exactly what we were spending money on.

In my case, I had about 30’ of copper pipe removed and replaced with Pex. I had separate contractors come in and remove Sheetrock and insulation, so all plumbers needed was to get to the pipes. Call the Whale wasn’t able to tell me how much the materials costs, but from researching multiple sites, the materials averaged out to be about $300-$500. They charged $4,800 for the service. I’m not familiar enough with plumbing to know what labor costs are and whether or not $4,500 is accurate for labor, but it definitely made it challenging to work with insurance.

In short, if you’re not having to deal with insurance, I would highly recommend this company. They truly were incredible to work with. If you are need of transparency with cost and want more than trusting fully in a system or algorithm to give you a number, you maybe look elsewhere.

Nic and Jeremy did a terrific job installing a brand new furnace (on a Saturday no less) to replace my old one which had suddenly began leaking water and potentially CO emissions due to a cracked secondary heat exchange.

They were very clean and respectful of the home; they started the job on time and finished quicker than expected! There was no hassle, and they clearly explained all the great work they had finished at the end of the process.

Drew from Call the Whale came to clean my dryer vent, this was my first time using them. The entire process from start to finish was excellent! They sent text confirmations and reminders and before he arrived they even sent a message saying he was on his way with a photo so I knew who to expect. Drew was super friendly and neat and tidy in his work. Great service all around and I wouldn’t hesitate to recommend them and use them again.

I had a complicated plumbing situation that I needed resolved, and CTW went above and beyond to get it all sorted out. Though their price felt a little high, I was eager to work with a company that was transparent, had expertise, and prioritized customer service. And I don’t just mean “being nice” customer service - I mean doing a great job and making it feel easy for me from start to finish. Ray and Dillon took extra time to make sure everything worked well before leaving, and helped me gain a better understanding of how my own systems worked. Their standard of excellence and pride in their work left me with a functional system and a confidence that I could call them back in if anything went wrong in the future. And they were easy to work with throughout. Call The Whale clearly takes pride in providing 5-star service, in fact they promised it right at the start. In the end, they very much delivered on that promise.

The Whale responded quickly to our call and we were able to have a technician here in a few days (it was not an emergency). Drew was here promptly and was familiar with our boiler and promptly diagnosed our problem. He had the repair done in a few hours. Drew was friendly, knowledgeable and explained the process. We will keep them in mind for any future heating or electrical issues. I would give them 5 stars, but I am not sure how reasonable the price was.

After my furnace stopped working and was Josh came to do an evaluation. He polite and professional pointed out the problems and gave me three options for replacing the furnace. Josh was clear about the positives and negatives of each option.

Kyle and Mark came two days later. The continued Call the Whale’s polite and professional service through out their interactions. They removed the old furnace and water heater installing a combi furnace.
They left the area neat and clean without any mess from the job. They walked me through the new equipment answering my questions with clear and precise answers.

Overall I had an excellent experience with Call the Whale and would definitely suggest them to anyone having problems with their furnace.

Years after a successful install, these folks helped with servicing, disconnecting, moving, and reconnecting one of the heat pumps - in a matter of days. Getting qualified help that quickly is rare, and much appreciated. It's also rare to see someone handling the smaller details and not just leaning on new unit sales; and it means they'll be selling me the replacement units when the time comes.

Vermont Energy Contracting installed 2 separate units (Heat pump hot water heater and a Weil McLain gas boiler) this winter. Both units were professionally installed and are operating efficiently. We highly recommend the team responsible for these installations. From the salesman Tim Goodrich to the plumber and installers, each one was courteous, answering questions and offering helpful information.

My furnace quit working last week & I reached out to Vermont Energy in a panic. They responded immediately & I had heat again in a few hours. Extraordinary communication skills, positive can-do attitudes, competent, responsive, trustworthy, reasonable, & quite simply all-around wonderful!
I wish I could give them more than five stars! They are the absolute best! I can not recommend them highly enough!

Casey and the Vermont Energy Contracting team have been awesome since I first called in May 2025. I spoke to a real human (I think it was Vicky?) who set me up with a prompt home visit, and quickly received the quote after the visit. I have asked for an upgrade on the quote and everything has been processed very quickly. I look forward to working with Vermont Energy Contracting to replace my boiler and will write another review with photos after the install!

Vermont Energy just installed a new furnace a heat pump to provide central air conditioning in a mini split in our bedroom. I am so pleased that I went with this company. Their crew is very efficient hard-working and they clean up great I am totally satisfied with the job they did I would recommend them to anybody.

VT Energy was recommended to me by a friend, and I'm so glad they did. Everyone at VT Energy was fantastic to work with! Communication about setting up a consult, the estimate, and the installation itself were prompt and professional. Thank you for helping us stay cool this summer!

This company was wonderful to work with. We had a problem with some equipment and they were unbeleivably responsive. They were able to correct the issue quickly, but the best part is how poilite and caring they were. From the office staff, to the techs who visited the home, we could not be more impressed. They were so careful to place down tarps so the rugs stayed clean as they were in\out of their truck. We cannot thank them enough!!

I had a new construction house built in 2023. Vermont Energy gave me a very reasonable quote for a ductless heat pump system for my home that ended up meeting the needs, and continues to be functional to this day. That alone is worth five stars. Over the last few years, I've had incidents wherein the folks at Vermont Energy really stepped up and went above and beyond.

My unit ended up getting damaged during home construction, resulting in a situation where the unit wasn't functional, and was making disconcerting noises. They immediately dispatched someone to take a look.

Two years after construction, I had solar panels put in. During installation, they damaged a coolant line during the hottest day of the summer. They escalated the issue, and dispatched someone to do the repairs and recharge the line, during their second busiest season.

Vermont Energy is thorough and transparent, which on its own is fantastic, but even more impressive is how attentive they are, even after the sales have been made, and installation is complete.

I'll be returning to them first on any future HVAC related projects moving forward.

The folks at N.E. Air were great to work with from the first phone call to the finish of the project! They are very courteous, knowledgable, and prompt. I would highly recommend them.

Amazing, polite, and efficient team! Would highly recommend!!
