"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."

"We had an absolutely fantastic experience with X&M Heating and Cooling! From start to finish, Richard was beyond responsive, professional, and genuinely a pleasure to work with. You don’t always expect replacing major home systems to feel stress-free, but Richard made the whole process smooth and even enjoyable. They replaced our AC/Furnace (Condenser, Coil Pack, and Heater) as well as our hot water tank—a big job—and the crew knocked it out of the park. Everything was installed with care, attention to detail, and a clear pride in their workmanship. Richard took the time to explain what was happening every step of the way, which gave us total peace of mind. What stood out most, though, was the responsiveness. Whenever I had a question, Richard was quick to answer, patient, and genuinely friendly—it felt like working with a trusted neighbor rather than just a contractor. If you’re looking for a team that does top-notch work - don't look any further."

"2/3/2021 - Glad to have found Pro Sky Wow, what a great experience I just had with Pro Sky! Our heat pump went out during an impending snowstorm. Two companies on Thumbtack were quick to respond. Pro Sky got the nod because they could dispatch a technician immediately. It mattered when our house was getting so cold so fast. It also helped that Frank explained clearly his companyâ s approach in his initial response. As soon as I confirmed the appointment with Frank, I received a text giving an ETA for technician William to come by. Oh, another thing I like about Pro Sky is they use the Housecall Pro platform to send me appointment info, estimates, and receipts. All were super clear, and the platform was so convenient. Back to William, he arrived promptly wearing a mask and minding his distance. He listened patiently to the long history of issues weâ ve had with our Carrier Infinity thermostat before setting out to run the diagnostic tests on our heat pump. The tests confirmed the system was in good shape, the problem was with the thermostat. William took the time to explain our options for a thermostat replacement and addressed all of our questions and concerns without trying to sell us any particular product (or service for that matter). That is how you earn trust and respect from your potential (and repeated) customers. We would like to rewire our full system to use a third-party thermostat, and we will request William for the job. Thanks Pro Sky! 8/18/2021 - A happy customer is a repeat customer Last week was my fourth service call to Pro Sky: (1) system rewired & thermostat replacement, (2) water heater replacement, (3) HVAC Spring services, and (4) A/C start capacitor replacement. Our A/C stopped blowing cold air on a near-100-degree day last week. Who you gonna call? Of course, I called Pro Sky. Frank reassured me he would always have availability for a loyal customer. A different technician this time, the process was the same. I received a text with a link to Housecallproâ s job description, arrival window, and estimate ($45 for a diagnosis visit). Santo arrived on time, made a quick diagnose (bad capacitor), provided a reasonable price quote for a replacement which we agreed to. He replaced the dual capacitor, did a health check of our A/C system and was done in about 30 minutes. Super efficient! The service fee was waived in our final bill. Our A/C has been running fine ever since. Thanks again, Pro Sky!"

"they are an excellent installer"

"The Company is untrustworthy with their Prices. They offer no detailed Invoice, and their charges are A LOT more expensive than other Companies, to the point where I had to file a formal complaint with the BBB. Never again."

"ARS's customer service is subpar. I called 6 times in one day to report an issue with a thermostat and each time I requested a manger to call me back to confirm that this repair will be covered by a ten year warrantee when I purchased the HVAC system just over 2 years ago. No manager called me back . when ARS finally called, their employee tried yet again to upsell me on some nonsense I was NOT interested in or needed. ARS changed my Apt from 2 -6, to 6-9 without notifying me. My AC is still down. I would never recommend this company to anyone. In fact I asked their tech to take a photo of my warrantee paperwork so that I would not end up arguing with them about coverage in the future. this is a horribly run business. I already reported ARS to the BBB. no chance they'll change their practices though. Their Techs are good, with lousy management. "

"Made appointment for them to come over for an estimate (which they charge for) between 9-12 today. They are a no show. I wasted the whole morning on them. DO NOT recommend."
