Friendly, Knowledgeable Staff

Lisa, Jodi, and Chris were all great to work with. Each really knew their stuff. I felt very comfortable doing business with Swiss Air.

Quick response, excellent service

New homeowner, air conditioner needed a little love. Gentleman came out the next day, was informative, patient, and fixed my unit. Signed up for the membership, which is a sweet deal.

Good service, Not sure the service contract is cost effective

Very nice employees. The cost of the service contract increased substantially with a slight decrease in customer service. I would expect for service to increase. In the fall I was not contacted at all for a Fall service visit. And I had to contact the company to schedule the summer appointment, which ended up being rescheduled 2x. I understand wanting to take care of people whose AC is not working, but being rescheduled more than one time is a bit much.

Had my system checked out for a leak problem, all my options were explained to me in a way I understood without being talked to, I will use Swiss Air for all future HVAC needs
