HVAC Repair in Greenwood, SC — Local Techs, One Call
If your house is too hot, too cold, or making a noise it never made before, we handle it. STM Heating & Air works on cooling and heating systems for homes across Greenwood, from older places near the lakes to newer builds out toward the highway. HVAC repair in Greenwood usually starts with a few questions about what changed and when, then a look at the equipment inside and out. We work on heat pumps, gas and propane furnaces, dual-fuel setups, ductwork and thermostats. Before you call, check the thermostat setting and the breaker. Then reach out and we will get you scheduled.

HVAC repair in Greenwood, the local picture
We handle air conditioning repair, heating repair and full system replacements for Greenwood homeowners, and you can call us to get a visit scheduled. Summers here run long and sticky, with humidity that keeps working your AC well after the outdoor temperature drops in the evening. That constant runtime is what wears out capacitors, fan motors and contactors, and it is why we see the most calls in July and August. Winters are milder, but a few hard freezes come through most years and that is when a heat pump with a failing reversing valve or a furnace that will not light gets noticed fast. Greenwood housing runs the full range, from older mill-village homes with retrofitted ductwork to brick ranches from the sixties and newer builds out toward Lake Greenwood. Each one has its own quirks in airflow and duct sizing. If your home has hot rooms or a system short cycling, tell us what you are seeing and we will start there.
Much of Greenwood's housing came up with the textile mills, so you find older frame cottages and mill village homes alongside brick ranches from the mid-century boom and newer builds out toward the lake. Older houses often have crawlspaces, thin wall cavities and ductwork added later, which pushes air conditioning and heating equipment harder than the newer construction does.
Our vans run US-25, US-221, US-178 and Highway 72 most days.

How soon can you get to my house in Greenwood?
Call us and we will give you a straight answer on the next available window rather than a vague promise. During July and August heat runs we book up quickly, so morning calls usually get same-day or next-day attention. If your system is completely down and the house is climbing, say so when you call so we can prioritize it.
Do you work outside Greenwood city limits?
Yes. We cover the surrounding Lakelands communities including Ninety Six, Hodges, Ware Shoals, Abbeville, Laurens and Saluda, plus the neighborhoods around Lake Greenwood. If you are not sure whether your address falls in our area, give us your road and crossroad and we will tell you.
How does pricing work?
Everything gets quoted in writing first, the visit, the parts, the labor, and work starts only when you approve.
What brands can you service?
As an independent company we service every major brand, from Carrier and Trane to Lennox, Goodman and Rheem, gas and electric alike.
How it works
- Step 1
Tell us the symptom
Call or fill in the quote form and describe what you hear, smell or feel. Warm air, short cycling, a breaker that keeps tripping. That gives us a head start on the likely cause.
- Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant performance and the outdoor unit. We work the crawlspace and the attic too, because ductwork and drainage cause more trouble than people expect.
- Step 3
You decide, then we fix it
We explain what failed, what it takes to repair it, and what we would watch next season. No work starts until you say go. Most repairs finish the same visit when parts are on the truck.

Why homeowners call us
- Mixed heating is normal to usHeat pumps, propane furnaces and dual-fuel setups all behave differently in cold weather. We know how a heat pump should sound in the thirties and when the backup heat is doing too much of the work.
- We go under the houseRed clay crawlspaces hide crushed ducts, sweating lines and standing water. Comfort problems often start down there, not at the unit, so we look before we start replacing parts you may not need.
- Plain explanationsYou get told what broke and why, in words that make sense. If a repair is a short-term patch on an aging system, we say that out loud so you can plan instead of guessing.
- One crew, six statesWe serve homeowners across Alabama, Georgia, Kentucky, North Carolina, South Carolina and Tennessee. Same approach in every one: show up, diagnose properly, repair what needs repairing, leave the space clean.
- All major brands, gas & electricOne independent crew for Carrier, Trane, Lennox, Goodman, Rheem and more.
- Straight answersNot worth fixing? We say that out loud, and often it saves you the visit fee.
