- SNSusan NunamakerAug 17, 20265.0We have found our go-to HVAC company! Our A/C went out on an incredibly hot weekend in August. After reading stellar reviews, we called Coster Heating & Air first thing Monday morning. They sent Caleb out that day to help us even though they were swamped with calls. Caleb was incredibly professional, polite, and respectful of our home. We assumed that anyone who came out would automatically point to our 29 year-old unit and recommend a replacement. Caleb never tried to sell us a new unit. He quickly figured out that our thermostat wasn't communicating with our unit and had us up and running in no time. He almost seemed apologetic that the fix was so easy. We were thrilled!! I am in real estate and will now be recommending Coster to ALL of my clients. The company was honest, reasonably priced for their time and expertise, and had us up and running the same day we called. We cannot sing their praises enough! Thank you, Coster Heating & Air!
- CHCarol HerringAug 5, 20265.0Tyler was very thorough. He found the problem and solved it.
- RERuthann EvansJul 17, 20265.0Caleb was wonderful! He came out to do bi annual service on our air conditioner today and did an excellent job. He was professional, thorough, and took the time to explain everything clearly so we understood exactly what was going on. Sherry in the office was such a delight to speak with. Every time I’ve called CosterHeating & Air, she and the entire staff have been friendly, accommodating, and helpful. It’s refreshing to work with a company that truly values its customers. I highly recommend Coster Heating & Air for their outstanding service and exceptional team.
