Review of Dor-Mar Heating & Air Conditioning

Woke up on a Saturday morning to find out my AC was not working. I bought this just last year. Turned out it was actually the furnace blower. Called the emergency dispatch and despite being full for the day they still came out on that same Saturday. They had to schedule the install of a new furnace on Monday and went and came back with a portable AC so it wasn’t unbearable. Was able to sleep while the rest of the house was 85 or hotter! They showed up Monday as planned and professionally installed it and cleaned up. Great experience!
