Frequently Asked Questions
What are the most common HVAC problems in Oklahoma?
AC not cooling, furnace not igniting, heat pump icing up, and strange noises top our call list. Oklahoma’s extreme summers stress AC systems hard, and ice storms can damage heat pumps. Most issues trace to deferred maintenance — dirty filters, coils, or slow refrigerant leaks.
How often should I have my HVAC serviced in Oklahoma?
Twice a year: a cooling tune-up in spring before the Oklahoma summer heat, and a heating tune-up in fall. Hartzell’s $229 tune-up covers both systems. PMA plan members get priority scheduling and waived dispatch fees year-round.

Diagnostic: $111, then upfront repair pricing before work begins. Common repairs: $150–$600. Full system replacement: $6,000–$20,000+ depending on type. Free estimates on new installs. Call 405-375-4822.
