Our Story
A Business Built on Honest HVAC Service
Three Jay Heating & Air started the way most good businesses do – with a conversation between people who saw something that needed fixing.
Our three founders come from different worlds. One spent years in cybersecurity, learning that systems fail when people cut corners and that the details you ignore are always the ones that come back to bite you. Another came out of logistics, where meeting a deadline isn’t a courtesy – it’s the job. The third spent a decade in the field, hands-on, diagnosing and repairing problems in homes just like yours. Between the three of us, we’ve learned that doing this right means being organized, being honest, showing up when we say we will, and never walking away from a job we’re not proud of.
We named the company Three Jay because it represents the three partners who put their names on every call we take.
We’re not a franchise. We’re not a call center that dispatches strangers. When you call Three Jay, you’re calling a local company where the people answering the phone know the technicians personally, and where your comfort actually matters to us – not as a tagline, but because our reputation in this community is everything we have. Whether it’s a routine tune-up, an emergency repair in the middle of summer, or a full system installation, we’re going to give you a straight answer, a fair price, and work that holds up. That’s the whole thing. That’s Three Jay.

How quickly can you respond to HVAC service calls?
We prioritize fast response times, especially for urgent heating and cooling issues. For emergency HVAC service in Greenville, we offer 24/7 support and work quickly to restore your comfort as soon as possible.
Do you offer emergency HVAC repairs?
Yes. We provide 24/7 emergency HVAC service for AC failures, heating breakdowns, furnace issues, and urgent system problems throughout Greenville and surrounding areas.
Should I repair or replace my HVAC system?
It depends on the age of your system, the cost of repairs, and overall efficiency. If your system is older, frequently breaking down, or causing high energy bills, replacement may be the smarter long-term investment. We’ll help you make the right decision—not the expensive one.
Do you service all HVAC brands?
Yes. Our technicians work on all major HVAC brands and system types, including central air systems, furnaces, heat pumps, and complete residential and commercial HVAC systems.
Do you offer financing?
Yes. Financing options are available for qualified customers, especially for major repairs, system replacements, and new HVAC installations.
How often should I schedule HVAC maintenance?
Most systems should be professionally serviced twice a year—once before cooling season and once before heating season. Regular maintenance helps prevent breakdowns, improves efficiency, and extends system life.
