I am a skilled professional that works for a Dor-Mar Heating & Air Conditioning company. I recently completed a furnace maintenance job for a customer in the area. The job involved inspecting the furnace, cleaning the burners, checking the thermostat, and replacing the air filter. I also checked the electrical connections and made sure that the furnace was operating safely and efficiently. After the maintenance was complete, the customer was very satisfied with the results and expressed that they would recommend our company to others.
