Thank you to hvac1000 & to hvacservicetech_07 for your input for my other post. I feel a lot better. The unit is only 5 yrs old, and the receipt said defrost control board, there was a loose terminal at Y2. This is all new territory to us, we use to have oil heat. We were sort of stuck with the service company, and they charge about 30% more than other companies, but the other companies won't travel here due to gas prices. We found this new company and they are more reasonable, plus offer plans where they service twice a year and cover part & labor for anything that breaks, except the compressor, that would be an additional fee to get that protection. Are these plans worth it?
