Gas Furnace Repair in Maryville, TN 37804-2707

“Aaron and Josiah were prompt in responding to my situation. My heat had stopped working during the night. When they completed the repair and the heat started back up, the thermostat registered 54 degrees in my house. I can only imagine what it was before I started a fire in the fireplace, turned on a space heater and fired my oven up to 375. It was brisk to say the least! Aaron went to great lengths to ensure the repair was done properly and worked effectively. As well, he answered my questions and ensured my understanding. These two are professional, personable, knowledgeable and thorough, all the while maintaining Covid awareness. Thanks,
Aaron, Josiah and A & L.”

Heat Pump Installation in Vonore, TN 37885

They returned at a later date to install emergency heating during this visit the installed noticed the unit wasn’t running properly and called the office to get a service tech to come out to investigate. Service was above and beyond. Nice to work with a company that cares about their customers.”

Air Conditioner Replacement in Maryville, TN 37803

“I saw an advertisement for A & L online, and called them to get a quote on replacing both of my dated AC units/furnaces. Was called very promptly to set up an appt for a quote, and received the quote the very same day. The salesperson, Ethan, wasn’t pushy at all and was very informative on all the products they had to offer. We discussed what was best for my particular house, and installation began within a week. The upstairs ac unit was a nightmare for them to install, but we never heard a single complaint as they worked through the process. They cleaned up each day, and communicated everything that needed to be done the next day. They finished the job in the time they said it would take, and then followed up to make sure everything was great! Very detailed work, and very pleased by the professionalism by everyone that showed up at my house. I would highly recommended them for any future jobs/repairs/replacements you need! On a 1-5 rating, they would definitely be a 10!!! Thank you!”

Air Conditioner Installation in Loudon, TN 37774

“A&L HVAC recently replaced our heat pump compressor and air handler (inside & outside units). Every step in the process was great. Aaron Sweetwood, owner, came to our home and presented 5 options. Additional sales reps are employed (Sherrie for one). Amos was the lead installer. The complete process from initial contact to final cleanup was great. We also have a maintenance contract for 2 units. Maintenance employees are 5 star. Without going into detail… they take all of the time necessary, and are the most thorough ever used. Response time for service calls has been exceptional even on weekends and once on a holiday. Thank you Steven and Ron. They also service units at 2 commercial buildings. Bryant authorized dealer, but they have serviced Rheem and Carrier for me also. First used them for troubleshooting at an office building. They found and fixed what others could not. Courtesy, professionalism, timeliness 5 star. Knowledge, expertise, workmanship 5 star.”
