Top-rated independent heating and cooling across north Georgia and the southern Appalachians
HVAC Repair in Alpharetta, GA — Local Techs, One Call
We handle heating and cooling work for Alpharetta homes, from a compressor that will not start to a furnace that short cycles on the coldest night of the year. If your system is down right now, call us or send the quote form and tell us what the thermostat reads versus what the house feels like. Most HVAC repair in Alpharetta comes down to a handful of usual suspects: a failed capacitor, a clogged filter starving airflow, a drain line backed up, or low refrigerant from a leak that needs finding rather than topping off. We work on heat pumps, gas and propane furnaces, dual-fuel setups and ductless systems.

HVAC repair in Alpharetta, the local picture
We handle air conditioning repair, heating repair and system replacement for Alpharetta homeowners, and if your house is too hot or too cold right now, call us and we will get you on the schedule. Alpharetta summers run long and humid, so an AC that cools but leaves the air damp is usually a sizing or airflow problem rather than a refrigerant one, and we check both before we quote anything. Winters here bring a handful of hard freezes, which is when heat pumps lean on auxiliary heat and homeowners notice the electric bill and the lukewarm supply air. Much of the housing stock is 1990s and 2000s two-story subdivision construction with a furnace or air handler in the attic and long duct runs to the upstairs bedrooms, so the second floor cooks in July. That is a fixable duct and static pressure issue, and we will show you what we find rather than just swapping parts.
Most homes here went up from the 1980s through the 2000s, with a steady run of newer builds since. Expect two-story brick and siding houses on slabs or in crawlspaces, split-system heat pumps or gas furnaces, and long duct runs through hot attics that struggle to keep upstairs bedrooms cool.
GA-400, Highway 9, Old Milton Parkway and Windward Parkway are the routes we cover from here.

How soon can you get to my house in Alpharetta?
Most Alpharetta calls are scheduled same week, and no-cool or no-heat situations get moved up ahead of maintenance visits. Call us with your cross street and what the system is doing, and we will tell you honestly where you land on the board rather than giving you a vague window.
Do you work outside Alpharetta city limits?
Yes. The same crew that covers Alpharetta also runs to Milton, Roswell, Johns Creek, Cumming, Duluth and Woodstock, so a Windward address and a Crabapple address are the same trip to us. If you are just outside those towns, call and ask. We will tell you straight whether we can reach 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.
