Red Rock Mechanical of Colchester, Vermont handles heating, cooling and plumbing, and Google shows it at 3.9 stars from 92 ratings. Its website lists heat pumps, ductless systems, central air, duct repair and zone controls, and names a service area that includes Colchester, Essex, South Burlington, Williston, Stowe, Montpelier and Saint Albans. A recent customer who hired the company for minor plumbing under a kitchen sink said that when an issue with the work turned up a few weeks later, Red Rock had the plumber back in less than two days, free of charge, and issued a refund with an apology. A customer with a dead AC said they were fit in the same day. When a water heater gave out over Memorial Day weekend, a customer said Doug came by himself on his way to his vacation, then Steve and Eddie replaced the tank, which was still under warranty. A 2024 customer whose mini split had stopped working said manager Max worked with the distributor so the needed components came at no cost, even though Red Rock was not the original installer. A 2023 customer whose on-demand hot water and heating system failed at 1am said Doug's workers arrived at 9am with a new system and installed it. A 2025 Reddit commenter on r/vermont said Red Rock Mechanical installed their Mitsubishi heat pump. A 2026 r/burlington commenter said they had good luck with Red Rocks on plumbing and AC jobs, and that its prices have gone up in recent years. Scheduling is where things go wrong. A 2026 customer said they booked an appointment and the company never showed up or called. A 2024 customer said Doug missed an appointment, then missed the rescheduled one too. A recent customer who called for emergency A/C repair at 5PM on a Saturday said the return call came around 7:30PM and the tech was rude and hung up. A 2026 customer said the company backed out of the plumbing work for a small bathroom renovation at the last minute. A 2023 customer said a 4-zone minisplit install had multiple refrigerant leaks and one zone never got cold. A 2022 customer said a small leak under a sink was left worse, with a broken pipe.
“Red Rocks has been the most consistent and professional company I’ve used. Their prices have gone up in recent years but I’m guessing everywhere else has too. I’ve had good luck with them on plumbing and AC jobs.”
“Red Rocks is the way to go”
“This was 2021 but we paid like $9000 for it Bosch through Red Rock.”
“Looking at invoice from Red Rock 1 year ago this month: Installation of one Bosch 151 Floor Greenstar Combi 95% AFUE Boiler - Price: $10,795.”
“Higher than we paid 18 months ago. Try Red Rock Mechanical.”

I hired Red Rock to help me with some minor plumbing issues under my kitchen sink. Their plumber came and was professional throughout. I was a bit surprised by the final bill, but that's kind of what you get when you hire a plumber, haha. A few weeks later there was an issue with the plumbing work he had done. I sent them a picture of what had happened. Red Rock had him back over in less than two days, free of charge, to correct the issue. They also issued me a hefty refund along with an apology. I appreciated their responsiveness and professional response, especially when I wasn't particularly polite with my complaint when I reached back out to them about the issue.
Red Rock Mechanical has been a reliable service provider for us. They fixed issues other companies were unable to properly address and we trust the thorough, neat, and on-time service they provide.
I called and they were able to fit me in same day! Got my AC running perfectly now!
Unfortunately it's not possible to choose less than 1 star. I called at 5PM on Saturday for emergency A/C repair. We have an elderly person and a medically fragile child living in our home. We left a message with the answering service and received a return call around 7:30PM. The tech (either Tim or Jim) was very unprofessional and rude to my fiancée and shouted at him saying, "You're interrupting my dinner!" and then proceeded to hang up on my fiancée. I have a suggestion -- maybe don't advertise 24/7 emergency service if you don't actually offer that. Extremely disappointed.
Scheduling a visit was efficient. Communications with the office were clear, friendly, and responsive. The technician was knowledgeable, efficient, polite, thoughtful, attentive, and professional.
