"I called to get an inspection done on my AC unit and was quoted $90 for the inspection plus $120 an hr for ADDITIONAL hrs. I ASKED when do I know when the “additional hrs start”, He stated that the tech would let me know once the inspection was done and then at that time he would let me know if there was work that needed to be fixed or if there was nothing then the service would end and I would only have to pay the $90. They charged me $210 for the inspection. I called and requested that we both listen to the call (Because all calls are recorded) They played the call, heard what the rep said and then stated they would get back to me. When I finally reached them again (they never called me back), they stated I would not get a refund, then replayed the call cutting out the part when the rep stated clearly that the service was only $90. They not only GASLIGHTED me, but they altered the recording. $120 may not matter to most but it sure matters to me."

Family owned & operated. Financing available. Credit cards. All work done by experienced professionals to ensure consistent high quality. Award winning company at your service.
"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."

Support a local minority-owned family business and hire me for any heating, cooling, electrical, or plumbing needs. I guarantee fair pricing, and honest hard work. I have over 20 years of experience in the field in both commercial and residential work. I am a certified HVAC Technician, and have worked as a Building Engineer with some of the top building management companies (Cushman and Wakefield, CBRE). I also worked with George Washington University as an Appliance Technician, the Port of New Orleans as a Plumber/Pipefitter, and with Norwegian Cruise Lines as a Marine Engineer/Motorman. If I can keep a ship floating, I can fix any home repairs you need! I specialize in heating and A/C repairs, but I'm starting out my business and looking for any opportunities to grow my customer network - able and happy to do other home repair jobs like welding, painting, mounting, snow or leaf removal, gutters, decks, drainage, and more! I even just mouse-proofed my house by installing a ridge vent guard and garage seal, and I could help you solve any pest problems too!
"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)."
