I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I recently completed a furnace inspection for a client. During the inspection, I discovered multiple issues with the system, including a faulty thermostat, a broken fan motor, and a cracked heat exchanger. I discussed these issues with the client and provided them with options for repair or replacement. The client opted to replace the system, and it is being installed tomorrow or Wednesday.
