Your Air & Heating Contractor
Killian's Air is a family-owned HVAC contractor serving St. Petersburg and Pinellas County. We service and install all major brands and 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 cooling season runs about nine months, so your AC runs far more hours than a system up north. We size every install properly, 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
We grew up in St. Petersburg, so we know what Pinellas County weather does to an HVAC system. Salt air near the coast corrodes coils and electrical connections, and a cooling season that runs most of the year keeps equipment working hard. We know what holds up here and what doesn't.
We start by listening. We look at your home, explain your options in plain language, and give you flat-rate pricing before any work begins, so you won't get pressured or upsold. Cool Club service agreement members also get priority scheduling and discounted repairs year-round.
Pinellas County has plenty of good HVAC contractors. We earn your business by showing up on time, doing the job right, and being there when you need us, including nights and weekends for emergencies.

Healthy air starts with the right equipment and proper maintenance. Our indoor air quality program includes HEPA filtration, UV purifiers, and whole-home dehumidifiers, which matter in Florida's humidity. We also specialize in coastal property HVAC, where salt air speeds up corrosion and calls for equipment built to last. Whether you own your home or manage properties, we match the solution to the building and your budget.
