We have been customers of Comfort Air for over the past twenty five years at two different homes in San Antonio. We have always kept the maintenance agreement on all of our heating and cooling systems and have enjoyed the friendly and professional service of the technicians. Eric Banda was just at our home to perform the fall check-up on our furnace. Eric was very professional and went out of his way to not track dirt into our home since it was damp outside. Eric also made recommendations about our heating and cooling system due to its age.
