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."

"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."
