You are looking at a project Cornett HVAC provided in Pasadena Maryland. This job was a simple repair that had a big impact on our homeowners. Recently, their furnace went down and the Cornett team came in to fix the blower components. After a little TLC, the unit was back working the way it should. If you or any of your friends are wondering if their furnace is going to last through the winter, give Cornett Heating & Coolling a call, and we will come out and give you an honest assessment of the situation. You will be happy to get ahead of it, before it's so cold, even one day with it not operable, will make you and your family looking for a hotel room, or family members home to stay in.

Michael arrived as scheduled, listened to the concern, and got right to work to solve the issue. Our heat was back up and running in less than 30 minutes and he explained what happened and what to do going forward to avoid the issue again. Thank you
