"I’ve been a loyal Snell customer for years, but this recent experience was deeply disappointing. After our AC failed in August, Snell diagnosed a leaking evaporator coil. We chose to replace the system through them, and the salesperson took time to evaluate the setup in advance. However, on installation day, the crew arrived without the correct ductwork and had to make adjustments on the fly. Unfortunately, the adjustments were poorly executed: • The Aprilaire humidifier was mounted on sloped ductwork rather than a level surface, contrary to manufacturer specifications. • The hole for the humidifier was cut inaccurately. • The drain line was left kinked in multiple places. Aprilaire support later confirmed the humidifier was not installed correctly and warned this could lead to water backing up into the system — a concern I had raised with the installers before they left. Despite multiple follow-up attempts, I received no meaningful response. I was told my concerns would be escalated, but no one followed through. This was a major investment, and I now feel I need to bring in another HVAC team to correct issues that should have been resolved from the start. I’ve recommended Snell in the past, but I can’t in good faith do so now after this experience."

"I had a wonderful experience with Founders Insulation. They were extremely easy to work with. It was easy to schedule an appointment, the gentleman who came out was knowledgeable and polite, and I felt that I received good information and they did not try to sell me something I did not need. Their quote was excellent. The work was scheduled and completed quickly. The installation team was courtesy, thorough, and knew their stuff. They were respectful of my home and went above and beyond. I highly recommend this company."

"Quickly diagnosed, fixed onsite, discussed what to watch for, and so friendly. Awesome service."

"Everyone needs a little Terry's Home Repairs in their life. Our oven digital display snapped off and fell through the opening. I talked to an appliance contractor [before finding Terry's Home Repairs] and he indicated that the whole control board would need to be replaced (at a cost of $430). When I asked him if he could provide a refurbished control board or if he can just resecure the existing display back to the opening, his response was "modifications" is not something he would be willing to do. At this point I began doing some research. I located Mr. Terry on Angi's List and after reading reviews and discussing the problem with him over the phone I decided to move forward. He provided an exact time he would be at the home and showed up right on time (on a separate but related note, I am really sick and tired of the 'four hour window' provided by the larger contractors - I am busy as h*** and do not have time to block off four hours of my day). Upon arrival, Mr. Terry identified the issue and provided a new bracket to secure the oven display. While there, he also fixed the exhaust fan (over the range) and also fixed a dryer vent that was coming apart. His price was fair and his work was good. I will be using him moving forward for 'odds and ends' and random things around the home. I like his background (he worked as a mechanic on a cruise ship and also worked in Alaska on HVAC related projects)."

"When it comes to offering home inspection services, I cannot recommend Chris highly enough. He arrived at my property before our scheduled appointment, and was thorough, espsecially when it came to explaining how certian utilities, like the water shutoff, water heater, fusebox and HVAC systems worked. I know he would be as thorough with your house as he was with mine."

"Our LG above stove microwave stopped heating. Lucky from Reliance Repair came out and gave us an estimate. He arrived on time. His estimate was reasonable. When he received the part, he returned on time and worked diligently to repair the problem. He was polite, respectful. Overall, an excellent repair experience. Highly recommended."

"It went great! Very professional work. They made me feel comfortable that my issue was handled."
