"Every thing went well, even though he had bad news that the unit needed to be replaced due to the fact that the unit was 18 years old and the refrigerant used in the day was R22 that it cant be purchased because of government regulations, now we will see what the estimate will be. The technician seems to be knowledgeable and was very professional about his work."

"I signed up for a service plan, as I’m not much of a handyman myself. They had a variety of payment options with the service plan, so I was able to start monthly payments, which works best for me. Our service person was polite, and he explained everything in terms I had no problems understanding. I had an additional issue with an attic duct being chewed through. He got up there and got pictures right away so they could put together an estimate. Same visit, no hassle. And because of the service plan, there was no charge for the system check. I just let him in, showed him around, and he worked his magic. No regrets here. There’s a very good chance I’ll just keep up this service plan for the entire time I own my home."
