Warranty Customers

Welcome to Falcon Heating & Air Conditioning! If you're a homeowner with an existing system that needs service or replacement, Falcon is here to help. We guarantee satisfaction and we back our work with a warranty! To submit a service request for a system still under builder's warranty, please contact your builder's warranty department directly.

Service Hours

We offer service to all homeowners with a Falcon installed system still under your builder’s warranty period, Falcon replaced systems still under our warranty period, and those that have a current service contract with us.
