My wife and I have have lived at our present location in Gahanna for five years and one of our smartest moves when we moved here was to contact Swiss Air for our HVAC Maintenance needs. The friendliness and professionalism of not only the office staff but especially the technicians that have performed our maintenance needs have been top notch. I want to give a special shout out to Joe and Mike for keeping our HVAC healthy. On Mike's recent visit I had mentioned that we needed filters and he returned the next day with two filters, he kept his promise! Thanks for your efforts.
