"Frank was excellent. He is very detail oriented and wants to do nothing more than an excellent job. The work he did was as if he was doing it in his own home. If you need work done and want it done right. Call him you’ll be glad you did."

"Indoor Comfort Team installed my HVAC system in 2019 and I have continued to use them for my regular fall and spring servicing. They consistently do an outstanding job. I had my most recent service done today, and the technician, Sabrina McIntyre, was no exception. She was prompt and efficient and carefully explained everything she checked. I was highly satisfied with her work. "

"Great! We were given the fee up front, able to schedule within a timely manner, and received the report back the evening the inspection was done."

"I previously worked with another company to replace my furnace. The first company was extremely flakey and would constantly cancel my appointments or simply not show up. Eventually, I decided to go on Angie's List, and I found Siefert Mechanical. This company was extremely quick to get to my house, give me an estimate, and then perform the service. Not only did Siefert Mechanical quote me a price that was $600 less than the first company, they also never cancelled or missed an appointment. They came out once to give me a quote, then the very next time they came out to my house, they replaced my furnace. The quality of their work is extremely professional, and I would HIGHLY recommend this company for any heating/cooling service you need performed."

"The gentlemen from Holper’s came a day early and broke in to my locked yard to obtain their trap. I had discovered that everything this company catches in traps, they KILL. There is no humane solutions to a critter in your attics with Holper’s. I have the footage from my camera of their employee hopping my privacy fence and removing the trap with the opossum in it. This gentlemen never went in to my attic and I am not sure he was even on the roof of my home. I have been billed $219.00 already and they are attempting to bill me another $109.00 to pick up their trap. I had already contacted a home pest service and he gave me instructions on how to handle the opossum and the trap before Holper’s came back. I will never do business with a company that breaks in to a client’s home against their wishes. Not a good way to please the customer."

"I purchased a new AC unit last summer. When firing it up last month, the motor was dead and required a replacement. The motor had to be ordered, and I was told they would cover the cost of the motor (I should hope so), but I'd have to pay for the installation. I feel that, when purchasing a piece of equipment that expensive, one expects both the vendor and manufacturer to fully stand behind their products. Obviously, they did not. I tried to call the service manager to discuss this, but had to leave a message since he wasn't available. No return call. When the repair person came out to do the installation, I also asked him to have the service manager call. Again, no follow through. CAC also schedules for full day windows. For many households, that is simply not manageable. We have jobs, and I think the CAC policy is simply indicative that they are taking their customers' needs seriously. I have no complaints about the service technician that did the repair"

"I was TOTALLY satisfied with the work Greentree did on my house. My contact guy was Mr. Bill Majers. He got up on the roof with the insurance adjustor and indicated all the places where there was hail and wind damage. They worked with my insurance company to get the entire project covered by my insurance. The roofers were fast and very efficient. I have nothing but praise for this company and for Mr. Bill Majers, who went out of his way to ensure everything was completed to my total satisfaction."
