R. C. Harmon & Co., LLC, of 400 Chapel Rd in South Windsor, holds an active Connecticut home improvement contractor registration, HIC.0553705. It has 3.7 stars from 12 Google ratings. In February 2026 a customer asked for a quote to replace a water heater the company had installed seven years earlier; Jen said she would probably have the old paperwork, but after two days and about four calls, messages and texts, she never returned the calls, and nobody answered when the customer phoned. In December 2024 a customer who had used the company off and on for a couple of years wrote that responses to service requests were at times very delayed and repair quotes were "all over the board"; after they could not get a reply about snowplowing, they were told on 12/12/24 that the company was booked for the year. In July 2022 a reviewer wrote, "We have used RC Harmon now for a few years for a variety of projects and repairs both inside and outside the house," thanked Gen for responsiveness and called the company "a general purpose contractor for any job big or small." In June 2022 Tom and Jeanette Bare, new to the Glastonbury area, described landscaping and inside home improvements, with researched suggestions before each job, a fair estimate and clean-up at the end. Greg Castanza of Glastonbury wrote in December 2022 that Reed in the field is courteous and Gen in the office is "absolutely incredible," and a May 2022 reviewer hired the company to mulch and clean up garden beds and bushes. In August 2022 a reviewer wrote that the company backed into a friend's car on a job and refused to make good on it; in January 2023 another wrote that a company truck was weaving in and out of traffic on Route 5.
I called RC Harmond to get a quote to replace a hot water heater that they already had installed seven years ago and Jen said that she would probably have the past paperwork to give me a new quote, I waited 2 days to hear back and called maybe four times left messages and texts and she never returned my calls I even asked her if they weren’t interested in doing the job to just text me and let me know your not interested, but never heard anything back in addition, the times I called nobody was ever there to answer the call, so based on their customer service I would say I would never use them or refer them to anybody else. Now this was my experience with them, I see that a few people really liked them, well I’m happy for you that they treated you so well, but obviously from my experience they don’t treat ALL customers they same.
We have used RC off and on for a couple of years, their response to requests for service have at times been very delayed and quoted costs for repairs have been all over the board. Quality of work is average to below average. We had them snowplowing for us for a couple of years but as a repeat customer could not get get a confirming response from them this year only to be told today 12/12/24 we’re booked this year find someone else. I would not recommend them to anyone.
Stop driving down route 5 like a looney and risking people's lives, This guy's company truck was weaving in and out of traffic putting people's life's in danger . This clown should have his license taken away and his business shut down.
Been working with RC Harmon for 3 years. Their customer service is exceptional. No service organization is perfect but a testament to good customer service is to be proactive and respond quickly to customer requests. Reed in the field always is courteous, receptive and willing to please and Gen in the office is absolutely incredible. And their pricing is reasonable and competitive which is great too. I highly encourage any homeowner or business to engage their services as I think you'll be pleasantly surprised! Greg Castanza Glastonbury
Backed into my friends car on a job and refused to make good on it. They got removed from the job and preferred to lose income than acknowledge a mistake. EDIT: 1. Don’t pretend you don’t know what I’m talking about. 2. I didn’t hire you.
