Your Air & Heating Contractor
Killian's Air is a family-owned HVAC contractor serving St. Petersburg and Pinellas County. We service and install Carrier, Trane, and Rheem systems — and every job uses flat-rate pricing so you know the cost before we start. From a seasonal tune-up to a complete system installation, we handle it all.
Florida's 9-month cooling season means your AC works harder than almost anywhere in the country. We use professional system sizing on every install, offer financing as low as 0% through Wisetack, and back our work with manufacturer warranties up to 10 years.
Whether you need an $89 diagnostic, emergency service at 2 a.m., or a new high-efficiency heat pump that cuts your energy bills year-round — Killian's Air is here to help.
About Us
Passionate about YOU & our community
As lifelong St. Petersburg residents, we bring a deep understanding of Pinellas County's climate and the unique demands it places on HVAC systems. From salt air corrosion near the coast to the 9-month cooling season that pushes equipment harder than almost anywhere in the country, we know what works here — and what doesn't.
Every interaction starts with listening. We assess your home, explain your options in plain language, and present flat-rate pricing before any work begins. No pressure, no surprise charges, and no upselling. Our Cool Club service agreement members also receive priority scheduling and discounted repairs year-round.
Pinellas County has many good HVAC contractors. We earn your business by showing up on time, doing the job right, and being available when you need us — including nights and weekends for emergencies.
