Unfortunately I can't recommend this company. I used Precision Comfort for a summer tune up. The owner Ray came out and claimed there were several things wrong with my hvac system which was installed by another company. He took my manual to do some research and said he would follow up up with me. I have left many voice and e mails and never get a response. I want to do business that follows up when a customer calls. They also have an F rating with the Better Business Bureau.
