How do you decide what size furnace my house needs?
We measure the house rather than match the old nameplate. Square footage, insulation, window count, duct layout and how the house sits on the ridge all change the BTU load. Oversized furnaces short cycle and leave rooms uneven, so we size to the actual heat loss.
Should I repair my furnace or replace it?
If the heat exchanger is cracked, or the part is obsolete, or you have paid for heater repair two or three winters in a row on a unit well past its expected life, replacement usually makes more sense. We give you both numbers and let you decide.
How long does a furnace installation take?
Most straight swaps take a day. If we need to correct venting, resize a return, run new gas line or move the unit in a tight crawlspace, plan on two. We tell you which one you are before we start, not after.
What is a high-efficiency upgrade actually changing?
A high-efficiency furnace uses a sealed combustion process and PVC venting instead of a metal flue, plus a variable or multi-stage blower. That means new vent routing and a condensate drain. We check both are workable at your house before quoting the upgrade.
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.
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.
