“Happy to find a trustworthy honest company that looks out for the customer.Brian came out on a Sunday evening to service us. Great work thank you for doing a great job ”

-Geri Huber

“Great experience.Brian diagnosed and fixed my a/c very quickly. Squeezed me in ahead of schedule on a Friday and I did not have to spend a weekend in a hot house. Very courteous and professional. Highly recommend!”


“Brian is a life saver! We went through our home warranty. The first company they wanted to send out couldn't get to our house for 2 weeks! During a heat wave! After a few calls back and forth we got a sooner appointment with Bast. Brian came in the time frame promised. Within 25 minutes of Brian being there the sweet, sweet cold air that hasn't blown in our house for a week began blasting out of our vents. Not only was Brian a genuinely a good person he's an extremely efficient and hard worker. I'll never use another heating/cooling company again.”
