I had the furnace checked by them in May and spent over a thousand dollars charging the AC unit. It was certainly cheaper than replacing. The blower motor checked out with their "Early Bird" tune up as operating under normal parameters. I went to cool the house recently and the motor failed to function. I called Apollo, the response was quick. they came out over the weekend and replaced the motor for a service fee of $89.00 and a motor cost of $585.00. After doing some parts checking the motor cost was considerably higher than what I could find on the market. I guess they had hidden labor and/or material markup in the motor. Other than the cost I would recommend them.
