My service appointment is always phenomenal with Del-Air. I have never before had such a thorough service. They spend so much time cleaning, testing, repairing, and just doing the job of maintenance. I am truly impressed and would never use anyone else. In addition, the service technicians are the most friendly and knowledgeable customer service oriented…

Called at 9pm and they were at our house the next day at 9am. Thorough evaluation , great communication, and fixed our problem without a hard upsell for a whole new unit. Honest service and I have great confidence with this company moving forward.

We have the annual maintenance plan with Del-Air for HVAC and this was our first appointment for our new system. The technician did a great job and was very thorough. He explained everything to us and was extremely knowledgeable. Highly recommend!

The technician was on time, polite, professional, and thorough. He explained what he was doing and went beyond simply correcting the problem by making sure the system was working properly. I have used Del-Air before and they don’t disappoint.
