“We had a new heat pump installed and the installers were very professional and courteous. 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.”

Air Conditioner Repair in Maryville, TN 37804

“Been homeowners for 20 years. We JUST used A & L Heating and Air after using a couple of other local company over the years. After seeing A & L recommended on a local site & suggestion page by another HAPPY customer I decided to give them a try. I was BLOWN away by the level of quality of this company on every level every step of the way!!!! From the courteous & knowledgeable office staff to the installers everyone was professional & helpful! I truly wish ALL services and fields of the service industry (electricians, plumbers, contractors, etc…) had experts set up to the level of professionalism as A & L (NOT JUST A CREW) as this company with the same quality of customer service they provide! We had a brand spanking new unit installed 6 years ago by a another heating & air company. I was paying that same company to have yearly "maintenance" on my unit (or so i thought) but it turns out i was being charged for services they weren't actually doing (found that out the hard way). The company sold me a unit 1 ton too large for my home and when replacing my duct work not only layed it out wrong to a fault they installed 3 different size ducts interfering with air flow and taking an unfortunate toll on our unit. With this "other" company NOT properly maintaining our unit and the poor movement of air we have struggled to properly heat and cool our home with our new unit. We chucked it up to East Tennessee conditions. Come to find out my heat condenser in our practically new unit is almost rusted through and will fail soon. This is an issue that SHOULDN'T have happend so soon in it's young life. Do yourself a favor and call A & L Heating & Cooling! You WON'T be sorry you did! Above i had to chose a service but we had our unit maintained, Duct work replaced, and a ductless mini split installed. I was able to evaluate the business in the following areas: repair, maintenance, & installation. For the first time in YEARS we've had adequate heating & air, even in these harsh Tennessee conditions! I actually get COLD in my house now! My only regret is not finding A & L SOONER!”

“This team couldn’t have been more perfect! They had quick availability, updated me and showed up on time for each appointment, did flawless work, and had convenient options for me to choose from. They explained everything to me in terms I could easily understand, showed me firsthand what I was dealing with, and followed up on their work. I’m very happy with the outcome and will definitely be recommending them to other family and friends!”
