Quick service, friendly, reasonable, on time!! And tech was knowledgeable
Dan did a great job of servicing my unit and explaining my options for a warranty plan and surge protector upgrade. Running great now!
Dempsey Energy responded quickly when our AC system died. Replaced system in one day under extreme heat conditions. Working a very long day in over 100 degree attic and in no shade yard David and Charles never lost their good humor. Completed everything that was in the quotation and and answered all our questions.
