He applied it to every tune-up since Hartzell’s opened and brought the same standard to the OKC metro. Two visits per year, spring AC, fall heat, with a written condition report, not just a sticker on the unit.

Why OKC Homes Need Annual HVAC Maintenance
Oklahoma City’s climate is hard on HVAC equipment. Summer temperatures routinely exceed 100°F for weeks at a time. Humidity swings stress refrigerant systems. Winter ice storms push heating systems to their limits. Oklahoma also has some of the worst air quality days in the region during wildfire season, loading up filters and coils. Annual maintenance catches problems before they become emergency repairs, and in Oklahoma, emergencies happen at the worst possible time.
