First time they came out I was thrilled he got my heater up and running but I opted to wait on repairs know we were heading into summer and didn't think AC would last. Shazam it did but the heater started to growl a horrible noise why starting up so I decide to have it fixed. Original estimate was for an induced draft motor $294. He did come out on thanksgiving eve he is very easy for appointments. But felt a hard sell to get my unit serviced $90 and even wrote on receipt Home owner declined heating maintenance, safety and efficiency check. Instead he installed a variable output motor which I had to call and ask what was done and the original service fee was not deducted. I did not ask, my bad.
