Heating & Air Conditioning / HVAC near Lebanon

“Delivers every time, professional, on schedule, and highly responsive. We really appreciate the proactive text and email communication for upcoming appointments and confirmation when the work is complete. Highly recommend.“

“Referral to neighbors during the heat of things was considered and acted upon by owners!“

“Brian did a great job! He explain everything to me that I need to have done on my ac. He cleaned up after he was done. Great with customer service.“

“We have had the best service from Zach! He's prompt, friendly, not outrageously priced and fully explains every option so you can come up with what's best for your needs. We've already used him at our house and business twice and will always reach out to him first.“

“We booked a full HVAC maintenance service for our retail store before the busy season. The crew arrived right on time, inspected the entire system, cleaned out dust and debris, and made a few small adjustments to improve airflow. They were careful not to disrupt customers and worked around our business hours. It’s been a few weeks since the service, and the difference in comfort is noticeable. The system runs more efficiently, and the air feels fresher throughout the store. Professional, reliable, and very respectful of our work environment.“

“Great service, very efficient and informative. Decent pricing, will not over charge you. Brian will go over everything with you so you know what is going and why. All in all great guy and great service, highly recommend for all heating and cooling services!“

“Woke up at 5:30 to get ready for work to a 78° home. Forecast was for 100°. Called them at bout 9 and the young lady said she would make some calls to her techs and lmk. She called me back and said that they could be there in the afternoon. I could have called someone else to see if they could be earlier, but I knew better than to bother. I know Kyle would take care of me better than anyone else. He showed up with Tanner. They had the problem diagnosed within minutes, went to their facility in town to get the capacitor, and had me buttoned up within the hour. It's great to have such a trustworthy, honest, professional HVAC business in Trenton. Go with them, you won't be sorry. Thanks from Don, happy customer!“

“Great company! They installed a water heater for me and a complete HVAC system in the past at a reasonable price. I would highly recommend them for services.“

“We have a 1.5 story with knee wall attics and it is much more comfortable now after having it air sealed and insulated. The upper floor is not hot anymore and we've needed to set the thermostat at a warmer temp or it gets too cool. That's a nice problem to have when you couldn't get it cool enough before. The basement isn't really cold anymore and there aren't the hot/cold spots in different rooms that we used to have.The team was great. Jim inspected the house and came up with the plan and Chris put the plan in place. The guys were there every day for some long hot days and always checked in morning and evening to let me know where things were at. Their attention to detail was impressive and they also cleaned up inside and out (no messes). Reliable and nice guys (that's hard when you've been in a 150 degree attic for days). We are very happy with Guaranteed Comfort. Thank you!“

“Very responsive, knowledgeable and reasonable pricing. I had them out to look at my AC unit. An actual person answered the phone and they were able to send a technician the same afternoon, on one of the hottest days of the year. He diagnosed and fixed the issue without trying to sell me anything unnecessary.“

“Wow! Airco absolutely bailed us out on this project. The Entire Hvac & Plumbing was a mess! Their teams showed up like clock work from the beginning of the project to the very last day! They crawled through nasty crawl spaces, they navigated the opossums in the crawl space, pointed out problems that needed addressed, offered professional advice & were kind courteous and fast! Thank you so much Daniel & Beverly Renfro, Darrel & Linda Renfro for all the incredible love you poured on our family. This project needed a little more horse power than I was capable of giving it. Thank you!“

“During heat wave I called Ehret and they came out same day. Cleaned AC unit, identified problem, had new moter delivered same day, unit no longer makes loud noises, and got COLD air back in my house. Also my father was going to pay 12k for new unit with another company but had Ehret come out 2nd opinion. Only a few hundred dollars later fixed his unit. THEY are the BEST!“

“From my initial call requesting a quote, to my first meeting with Chris and all communications throughout the entire process with both Nicole and Chris…our expectations were exceeded! They installed our new AC unit and Furnace this spring and just finished installing a liner in my daughter’s chimney (previous HVAC company didn’t deem necessary??). Chris and his installation teams are very knowledgeable & trustworthy! We highly recommend these guys, they know what they are doing! Thanks again for the awesome experiences!!“

“Great experience! Office returned call quickly and was able to send someone out to check that day. They were able to install a new furnace/AC before the temperatures dipped. Very thankful for them making sure our family stayed warm. Very professional and knowledgeable. Thank you!“

“Came out to do annual boiler maintenance. Excellent as usual and a good value. Will even be getting a rebate this time. Great people and I would recommend them.“
