Service technician was punctual and thorough. He encountered unforseen issues but was able to solve them in a very professional and courteous manner. All my dealings with this company have been outstanding. I would highly recommend them to everyone.

Climate Experts of Delmarva quickly responded to an a/c issue we had in a 4 level townhouse. The technician arrived on time, diagnosed and corrected a complicated problem, then followed up with an explanation of what was done. Very prompt and professional. Highly recommended!

The Climate Expert team notified me of a service window and came within the time expected with a “heads-up” notification from the service tech person, George, when he was arriving. They were quick to get started and ran diagnostics and was able to pinpoint the problem within a few minutes. Once the job was completed, he showed me the repair and made some suggestions on maintenance plans and follow steps. The invoicing was quick and paid on the spot. I am glad Climate Experts are modern and communicate well. They are a breathe of fresh air on how service vendors are supposed to operate their business but especially within the Ocean View/Bethany Beach area.

Our dryer vent project was a lot more complicated than any of us expected. The CE guys just kept trying new approaches to get the job done with minimum disruption to the house. They ended up putting in a lot more hours than estimated, and they only charged us for a fraction of the additional time. We’re happy campers.

Came out right away on a holiday created a temp fix until they can come out next week. Even discussed some other work. Nice and friendly and explained everything.
