Had a Solenoid replaced on air unit. Only 3 screws to put in, cost $40.00 (part). Told them the problem beforehand as I knew what it was. Came without the part, and disappeared for 40 mins. Had the unit open for them, all ready. 3 screws to put the new one in. Received over 175.00 bill. Didn't take a minute to do, and they are right down the street. Only reason I let them do it was to avoid elect shock. Noticed today, a sink they replaced already chipping. Previous sink in over 40 years. This is going on 7 years. Hence the review...
