HVAC reviews in Colchester, Vermont

I have used red rock in the past and had great service. I contacted them over a month ago to replace my cooling unit. We set a date 3 weeks out. The week before they were due to show I messaged to confirm and got told it would have to be another week due to supply issues. That appointment came and my husband is waiting at the house and hears nothing from them. I call to ask what's going on and get told he will find out and call my husband. Instead of having the guts to call and talk to us because they had to cancel yet again he sent my husband a text.

You have to hound this company (for us it was 4 separate requests across several months) to complete the actual work that their technicians recommend. When you finally get them to come out, they certainly can't come within the specified time frame, and later blame the customer for the incompetence of the business. This has happened on multiple occasions. Avoid!

I had booked an appointment with them and they never showed up or called to let me know they weren’t going to show up. After reading other reviews, this seems to be a common thing. They must be doing well enough as a business to blow off potential sales/customers, but they won’t be getting mine.

We hit the Heat Pump installation lottery with Doug and his team over at Red Rock Mechanical! Had it installed last week, just in time for the 100+ degree day we are having and we couldn’t be happier! In fact, last night, our three year old asked me to “move the sun to make it warmer” because he thought it was chilly in the house!

Absolutely impressive. Very helpful and knowledgeable crew. Helped get our furnace back to standard immediately and have been very gracious with educating my partner and me on how to maintain our furnace. 100% would recommend to anyone

Red Rock Mechanical has replaced our hot water heater and gas furnace, installed a whole house humidifier and done some smaller plumbing jobs including an emergency where they showed up about 90 minutes after my call. All good work no problems. They are always courteous, efficient and happy to share knowledge when I ask maintenance questions. They are my go-to HVAC outfit. Good guys. Shout out to Kurt and Eric, founts of knowledge and good HVAC advice.

I very seldom write reviews but feel compelled to give at least 7 stars to Doug and his team. My water heater gave up on me Memorial Day weekend, Doug came by himself on his way to his vacation to take a look! Yup, I needed a new tank and he got Steve and Eddie here to remove the old one and replace with new. Thankfully still under warranty! They were kind, courteous, more than helpful and even helped me with a chore that I couldn’t do by myself. That’s service above and beyond. I could not recommend them more highly!

We are in the process of getting our home ready for sale to relocate out of VT. I tried some companies I was familiar with their names, but they were not taking on new clients. My sister's realtor provided Red Rock Mechanical, they were accepting new clients, we made an appointment. They came out within two weeks to inspect our AC unit and the only thing it needed was a re-charge. R22 isn't a freon that is typically on hand. They came back about a week later to re-charge our system. Noah was awesome at each visit. Friendly, knowledgeable and honest. Honesty is hard to come by these days. I'd recommend Red Rock Mechanical to anyone and will certainly pass along their name to the new buyer. Thanks Fran Dartt

AC down at elderly parents during the stretch where it was in the 90's and humid. Father called and they said it'd be 3 months. I called twice (because that's obviously not going to work) and they assured me I'd be hearing from someone to diagnose the issue. 2 weeks later I finally got a call back. Unacceptable!

I would give them a zero if I could. Never have been treated so poorly as I was when I wanted to have my heat pump cleaned. Someone came out and cleaned for $250. Then they wanted to charge me $500 for a bib cleaning! I was told the heat pump cleaning was going to be less than $200. When I called and talked with the service manager I didn’t feel like they cared one way or another if they kept me as a customer. After working with the public for thirty years I would definitely handled this differently. But that’s Ok I went to another local business who was happy to have me as a customer and charged me wayyyy less than $500 for a bib cleaning. They did me a favor! You know when you spend a few thousand to have a heat pump put in you like to build a relationship with them to continue to purchase and get there services. All and All they did me a favor. I like good customer service and I didn’t feel I received it.

We had Chuck’s install 2 heat pumps in our home in South Burlington in 2015. We also hired them for the annual contract for preventative maintenance. We started spending our winters down in Florida - after 10 years of hiring Chuck’s for our Annual Contract for heat pumps and furnace, we came up from the south in May 2024 to find the heat pumps not working. Chuck’s suggested that they were too busy and we should hire someone else to take care of that and we did. We had the same problem in May 2025 and the response from Chuck’s was that since we had someone else work on our system they would drop us us as customers. After 20 years and spending close to $50k on a local business they decided to drop us as customers. All the great employees that I worked with, at Chuck's, have all left and apparently the new service manager has been calling the shots and dropping customers. I got our system changed by another local contractor on time and budget. Shame on Chuck’s for dropping customers who supported them for close to 10 years. No wonder they are losing customers left and right and I will be sad to see this local business fold down due to some eccentric employees.

Kind of late in summer season to have our AC inspected under our annual service contract but do want to note we appreciated the inspection and service to assure us everything working fine. Particularly want to mention technician Bryce who did a great servicing HVAC system. He was professional, courteous and thorough inspecting and cleaning system and explained how everything was working. I’d recommend Chuck’ s. Hopefully, we won’t have to wait til spring for heating system service and Chuck’s will schedule that before winter.

Chuck's Heating is absolutely fabulous to work with. I had a custom job where I was replacing my kitchen crown molding with custom metal trims, they can out and measured and then when we needed to make slight adjustments afterwards Gary and Joann were totally accommodating. They take real pride in their work. Thank you!

Terrible customer service! Had been a customer for 14 years. Then I had to change my email address. Well they didn't get it right which may be understandable. They like to think they are on the leading edge of technology via communicating through email. But it doesn't work.... Anyway, I tried to hold them to task and getting the email corrected and for over 9 months nothing happened. When I questioned why, Rob told me he would get it straight. Well he didn't and in fact went the other way and told his boss, I'm a terrible person and Chuck's shouldn't keep me as a customer. When I called again after Rob failed to deliver, I spoke with a person named Dave (later found out he is the "boss"). Dave didn't identify himself to me at all and called me "abusive" and stated they didn't need my business - already had too much business! In fact Dave didn't even let me address the issue at all and then hung up the phone. Mind you, I never called anyone at Chuck's a name, never raised my voice and never swore at anyone. In my 40 years of customer service, the first thing I did was to determine what the issue was and then determine how we might resolve the issue - called investigate and resolve. Not the procedure for Dave and Chuck's. Nope, just tell the customer they're done and to go away. Would not recommend them for any work!.

A crew from Chuck’s was here the last five days installing a 2 outdoor unit, 6 indoor unit ductless heat pump system in our home in Williston. Not only was the crew punctual, respectful and professional, they also went the extra mile to work with me to make sure the slimducts outside looked exactly how we had hoped. I work from home so was here for the entire install, but never once felt the need to check up on this crew. I can’t recommend this company highly enough if you want a great Mitsubishi mini split heat pump system installed.

Worst experience possible. New house so it should’ve been easy. They had it ALL wrong. Once they realized that it was bad, they were forced to try and fix their mistakes. They couldn’t even do that correctly.
Warning if you want a quality HVAC installation look elsewhere. Zero pride.
If you value good craftsmanship, honesty, and what you’re promised then don’t use Chucks. If I could give ZERO stars I would.
