About Three Jay Heating & Air

Greenville's Local Team for Heating & Cooling

Three Jay Heating & Air was founded by three partners with one shared belief: HVAC service should be honest, dependable, and done right. With backgrounds in hands-on HVAC work, logistics, and cybersecurity, we bring technical experience, attention to detail, and accountability to every job.

We’re a locally owned Greenville HVAC company, not a national franchise. Whether you need AC repair, heating service, or a complete system installation, our team takes the time to understand your needs, explain your options, and provide fair, upfront pricing. We believe in treating every customer the way we’d want to be treated. Our reputation depends on every appointment, so we focus on respectful service, careful troubleshooting, and treating your home with care.

What We Do

Heating & Cooling Services for Every Season

From an AC that won’t cool to a furnace that won’t start, Three Jay helps homeowners and businesses across Greenville and the Upstate get their systems working properly. We handle repairs, replacements, installations, and maintenance, with recommendations based on your equipment and the problem you’re actually experiencing.

Air Conditioning

AC blowing warm air, running constantly, or struggling to cool your home? We diagnose and repair cooling problems and provide installation, replacement, and maintenance to keep your system working through Greenville’s hot, humid summers.

Heating & Furnaces

When your furnace won’t start, certain rooms stay cold, or the heating system keeps shutting off, we’ll work to find out why. Our heating services include furnace repair, installation, replacement, and routine maintenance.

Heat Pump Services

Your heat pump handles both heating and cooling, so problems can affect comfort in any season. We provide heat pump troubleshooting, repairs, installations, replacements, and maintenance for Greenville-area homes and businesses.

Indoor Air Quality

Dust, humidity, weak airflow, and uneven temperatures can make your home uncomfortable when the HVAC system is running. We offer filtration, ventilation, and ductwork services to address the conditions affecting your indoor air and comfort.

Preventative Maintenance

Your system shouldn’t have to break down before it gets attention. Seasonal HVAC maintenance helps identify worn components, restricted airflow, and performance problems that affect everyday comfort before the next stretch of extreme weather.

Emergency HVAC Repair

No AC during a heat wave? No heat on a freezing night? Three Jay offers 24/7 emergency heating and air conditioning service in Greenville and surrounding communities when your comfort can’t wait for regular business hours.

Local Greenville HVAC Experts

We’re based right here in Greenville. When you call Three Jay, you reach a local team that knows the technicians and understands the communities we serve.

Honest Repair & Replacement Advice

Not every older system needs replacing. We look at what’s wrong, explain the available options, and help you weigh the cost of repairs against the condition of your equipment.

Experienced HVAC Technicians

From troublesome AC units to furnace faults, heat pump problems, and new installations, our team brings practical troubleshooting and hands-on HVAC experience to the job.

Upfront Pricing Before Repairs

You’ll know what work we’re recommending and what it will cost before you approve the repair. We want you to make the decision with the facts in front of you.

Financing for Qualified Customers

If a new system is the right choice, ask about available financing options. We’ll walk you through the current programs and explain how to apply during your installation estimate.

24/7 Emergency HVAC Service

Heating and cooling problems don’t always happen during business hours. Our emergency service is available day and night, including weekends, when you need urgent HVAC help.

Why Choose Us

Why Homeowners Choose Three Jay Heating & Air

Choosing an HVAC company means trusting someone with your home and a potentially expensive decision. You shouldn’t have to guess what’s wrong, wonder what a repair will cost, or feel pressured into buying a new system before you understand the problem.

 

At Three Jay, we believe good service starts with listening, careful troubleshooting, and a straightforward explanation of your options.

After getting a diagnostic and quote from our neighborhood’s go to company, we were not only shocked at the price, but to the extent of what the damage supposedly was. Three Jays treated the issue like it was a walk in the park and had our system up and running all in a days worth of work after the previous company stated that a full replacement could be needed. Thanks Three Jays!!

Three Jay and the team did an amazing job on my mini split. Brought in an electrician, who also handled my studio lighting. Very professional team, priced right the first time, I was preparing for a battle but they came in right in line with the research I put in for the install. Will be the only team handling my heating and cooling!

I would highly recommend Three Jay Heating and air. Jaret came out today and took a look at my HVAC unit it went down they found the issue and was able to assess it and give me a quote. They found the part in stock and was able to get my unit back up and running before 12 noon the same day. These guys were fantastic they didn't try to sale me on all kinds of stuff I didn't ask for like most of the companies out there. They were friendly, polite and easy too talk to and definitely a fair price. If I'm in need of future Heating and air issues again I will definitely call Jaret at Three Jay Heating and Air Thank you again for everything y'all did today.

On time and very knowledgeable with fast and reliable service. They didn’t try to upsell me on anything and they didn’t hide any fees. What they said on the brochure is exactly what I ended up paying for.

Three Jay Heating & Air provides residential and commercial HVAC repair, installation, replacement, and maintenance in Greenville, SC. Our services include AC repair, furnace repair, heat pump services, ductless mini-splits, indoor air quality, and ductwork solutions. Whether your system needs a repair or a complete replacement, our team will explain your options and help you decide what makes sense.

HVAC repair costs depend on the problem, replacement parts, and labor required. Three Jay offers an $89 HVAC diagnostic to identify the issue and explain your repair options. You’ll receive upfront pricing before approving repairs, so you can make an informed decision. We also provide free estimates for new HVAC installations and system replacements.

Not every aging HVAC system needs replacing. The right choice depends on its condition, repair costs, previous breakdowns, and overall performance. A minor repair may keep your system running reliably, while repeated expensive repairs could make replacement more practical. Three Jay evaluates your equipment and explains both options without pushing an unnecessary replacement.

If your AC runs constantly but doesn’t cool your home, possible causes include a clogged air filter, restricted airflow, frozen evaporator coils, refrigerant problems, or faulty components. Start by checking your thermostat settings and air filter. If the problem continues, Three Jay provides professional AC repair in Greenville to identify the cause and recommend the appropriate solution.

Yes. Financing options are available for qualified customers, especially for major repairs, system replacements, and new HVAC installations.
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.
