See What Our Customers Are Saying

  • Kara S. and Jacob B. both exemplified the utmost professionalism. Kara was excellent at scheduling and confirming that the scheduled time frame was convenient for me. Furthermore, Jacob B., the Service Pro, was kind, proficient, and highly meticulous. Air Comfort is a first-rate, first-class company that my family not only trusts but is a blueprint for other businesses and is the “gold standard” in air conditioning and heating services.

    Chris D.

  • Been using Air Comfort since our home was new built in 2005. John P has been coming into our home twice a year for the past 6-7 years. He is trustworthy, the consummate professional as he is always polite during his interactions with me or my family members. John has a vast knowledge of home mechanics on top of his excellent customer interaction skills. He can be counted upon to explain all options should maintenance to our HVAC system become necessary. The company as a whole is very easy to do business with, from calling the office to set an appointment for scheduled maintenance; to the technician (John P) knocking on your door. After all, you could call anybody for service… remember that’s who’ll you get showing up at your door, anybody. Air Comfort Service, the professionals you can trust.

  • I have been dealing with Air Comfort for a few years now. I like their service plans. Their Service Pro, John is so knowledgeable. He will stay on the problem until it is completed and is correct. He is always willing to take the time to answer any questions I have so that a novice can understand them. Thank you John.
