Super tuneup on a 1981 or 89 central electric air handler. There is no AC in this home the only heat source is a 15 KW heat strip and a blower. Ultimately it’s running fine though I have strongly recommended to the homeowner to go ahead and get a heat pump system that will run much more efficiently in the cooling and heating season. Customer will be calling office to set up an appointment for a comfort adviser when they are ready.
