For that reason, I had them do a spring checkup, Emma claimed the heat exchanger was cracked, the fly wheel needed cleaning, and the a/c compressor was "over amping." I had a different, highly reputable company check the furnace and a/c, and they found that none of this was true - neither the furnace nor the a/c had any problems. Also, Emma did not provide a written a written description of her service and recommendations, and they have not provided the promised receipt for the payment of the second inspection. They are either incompetent or dishonest, very possibly both.

Tyler came out and found no issue with furnace. 2 days later Bill came out and after 3 hours found that the thermostat wasn't communicating fully with furnace. Still no repairs made. Bill returned a day later and moved thermostat to lower level next to furnace in so it worked thru winter storm and gave me a bid of $400 to move thermostat back to original location in family room. After reviewing the path of the wires through the garage, up into a closet, and finally in through the wall, I decided their were too many possible points of failure and decided to leave thermostat in lower level but needed it moved over a foot so as not to impede doors covering HVAC area. Bill said the cost will be the same per company regs and wouldn't re-bid the job even though it was significantly less time and labor than the previous bid. He also needed to reconnect the A/C so I guess I'll find out this summer if that was done properly. I cancelled on the spot and will hire another HVAC company in the future to move the thermostat 12 inches to the left so I can close the closet door and test the A/C. I'm extremely unhappy.

It was time to replace a 30 year old system. The moment I opened the front door and met Tyler Koonce, I relaxed and realized I was in very good hands. I can't say enough good things about Tyler. He's mature, professional, knowledgeable, an incredibly hard worker, and just a nice person. Tyler explained everything that would occur that day and encouraged me to check in on the progress at any time and ask questions, which I did. His colleague Chris joined him and the two of them spent the next five hours installing the new Lennox system. The two of them did a great job and were a great team. When they were finished, they reviewed what they had done, answered my questions, and showed me how to use the new thermostat. They made the entire process easy and interesting and even fun with their good humor. The new Lennox system is working beautifully and is making all the difference. Thank you, Tyler and Chris! You and Level 9 are the best!
