Killian's Air Conditioning and Heating Services LLC is a family-owned HVAC contractor based in St. Petersburg, Florida and serving Pinellas County and the greater Tampa Bay area. The owner is a lifelong Pinellas County resident who grew up in the same neighborhoods the company now serves, and the business describes itself as a local company rather than a franchise or a national chain. The team services and installs all major brands and systems. Work covers AC service and repairs, air conditioning installation, AC system replacement, AC maintenance and tune-ups, heat pump installation and repair, ductless mini-split systems, heating installation, ductwork installation and repair, smart thermostats, duct cleaning, and indoor air quality equipment that includes HEPA filtration, UV purifiers, and whole-home dehumidifiers. Every job is quoted with flat-rate pricing, so the full cost is presented before the work starts rather than after it finishes. Killian's Air provides 24/7 emergency AC repair across its service area, including nights, weekends, and holidays, and states that callers reach a real person. The company is a Florida state licensed HVAC contractor under license number CAC1823158, is fully insured for general liability and workers' compensation, holds EPA 608 certification for refrigerant handling, and carries Carrier, Trane, and manufacturer-certified installation training. Financing is available through Wisetack for amounts up to $25,000 with terms from 3 to 60 months and APRs ranging from 0% to 35.9%, using a soft credit check for prequalification. Killian's Air also runs a Cool Club service agreement for members and points to coastal property HVAC work, where salt air speeds up corrosion on coils and electrical connections.
