Our story
PJ's Heating & Cooling was founded in 1970 in Marion, Ohio. What started as a small family operation has grown into Marion County's most trusted HVAC company — but we've never lost the values we started with.
PJ's isn't a franchise or a call center. When you call us, you're talking to people who live and work right here in Marion. Owner J. Aaron Mollett and our technicians are your neighbors — and we treat every home like our own.
We give you a clear estimate before we start and we never push repairs you don't need. That's how we've stayed in business for half a century — by earning trust one job at a time.
We're an authorized American Standard dealer and service every major HVAC brand — Carrier, Trane, Lennox, Goodman, Rheem, York, and more. Our technicians stay current with ongoing factory training.
No heat at 2 AM in January? No AC on the hottest day of the year? We answer the phone 24 hours a day, 7 days a week — because HVAC emergencies don't wait for business hours.
