Bought a new HVAC system from McCullough last year. Eric S came out to address some noises it was making. He was extremely thorough, identified both issues, and completely resolved them. I have an old house built in 1960 and my indoor unit is in a closet. To remove condensation I have a sump pump below the closet. On many occasions the pump was running much longer than it had when it was first installed. Eric found that somehow some of the tubing to the sump pump had a kink in it. Instead of just straightening out the kink, he completely replaced the hose and secured it so it wouldn’t move in the future and kink up again. The other issue was a small but persistent noise that happened every time the fan came on. That seemed more difficult for him to identify the cause, but he eventually removed the entire fan and casing and found that a small piece of insulation had become lodged in the fan so it hit like a playing card on a kid’s bike wheel every time the fan turned on. I was so thankful that he was as diligent as he was. Both were minor but annoying issues. With my office right beside the hallway where the unit is, I know every sound that thing makes. And now, it is as quiet as a mouse! Thanks, Eric! AND, because I pay the monthly maintenance fee, even though I’ve had the system more than a year, the visit cost me nothing. Thanks, McCullough!
