We had a/c here last week to fix a capacitor on our a/c unit and signed up for their maintenance program. They came today to clean everything and do checkup and said the heat strip in our heat pump was burned out and we were lucky we didn't have a fire or smell smoke. We had neither of these things. The picture he showed me had some ashy looking stuff in the unit and said that was what happened when it blew out. He said it will cost 415 to replace. I have never used this company before and wanted to make sure I wasn't getting snookered. Does this sound legitimate? We do live in an area that can dip down to 0 in the winter but not too often.
Heat pumps work by "harvesting" any heat in the outside air to heat your home, but there is a limit to what they can do so they have heat strips for when the outside air drops below 40F. Heat strips do burn out. Whether or not yours is really burned out or this guy is "snookering" you is something we can't help with.
