"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."

"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

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)."

Energy Efficiency Auditing questions, answered by experts

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.
