Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.
Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
Most furnace breakdowns come from a handful of parts: flame sensors, igniters, inducer motors, and control boards. We find the one that failed and fix it, usually in a single visit. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.
Not sure if you need professional help? These are the most common heating and cooling problems we fix in homes across the area.
Warm air from the vents usually traces to a weak capacitor, a refrigerant leak, or a frozen coil, all fixable, and all diagnosable in one visit.
AC repairFrequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.
Furnace repairEnergy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.
Maintenance & tune-upsA system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.
System replacementDust settling everywhere within a day of cleaning, musty odors when the system kicks on, or allergy flare-ups indoors all point to the ductwork.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
Lasting comfort comes from fixing the cause, not the symptom. We find why your system failed and shut that down for good, then back the work with a real guarantee.
Year after year, Alpharetta HVAC has been the team local families call when the AC quits or the furnace goes cold. We've serviced systems in nearly every neighborhood around town, and that track record shapes how we approach each job, from the first diagnostic to the final test.
Our team doesn't just swap parts and leave. We know the failure patterns, duct issues, and code details common to properties around here. This local knowledge means we catch problems other companies miss and keep your home comfortable.
One call connects you with a nearby technician who can size up the problem and get you a quote.
Our 4-step process is designed for accuracy, speed, and zero surprises on the invoice.
Call (470) 200-3255 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
A technician evaluates the unit on-site, confirms exactly what's wrong, and lays out a plan and a price before any work begins.
We complete the approved work on the spot whenever possible: quality parts, code-compliant connections, and no shortcuts hidden behind the air handler.
Before we leave, the system is tested end to end and your questions are answered. Seasonal tune-up plans are available to protect the investment.

There's no mystery to how we handle an urgent failure. Here's the step-by-step of what we do after a homeowner calls for fast help.
The first call is where it all starts. Someone on our team picks up, works out how urgent the situation is, and schedules the soonest visit available, while telling you the few simple things to do in the meantime.
Our experienced technician reaches your location with diagnostic tools and the common replacement parts ready to begin on arrival. No waiting weeks, no runaround.
This is where the problem actually gets solved. We repair what's repairable immediately, and when replacement is the honest answer, we handle removal, disposal, and a code-compliant install without drama.
We verify the fix held and answer any questions after the visit. For older systems we recommend a maintenance schedule to extend the system's life, which is the cheapest comfort insurance there is.
"The furnace kept short-cycling, kicking on and off every few minutes and never really warming the house. The technician diagnosed an overheating issue in minutes and sorted it in one visit. It runs like new now, and he showed me which filter to buy going forward."
"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, the airflow from every vent is noticeably stronger, and my wife's morning allergies have all but disappeared. They showed us before-and-after photos of everything they pulled out."
"Our restaurant's rooftop unit failed on a Friday with a full weekend of reservations booked. Their team got it running the same day. They clearly understood what downtime costs a Alpharetta business, and they came back the next week to fully service the second unit. Customer for life."
Choosing who works on your HVAC system is a real decision. Here's why local families choose Alpharetta HVAC.
Real experience isn't optional on our team. It means every technician reads refrigerant and electrical faults correctly, works clean and safe, and explains the work in plain language at a level most companies don't reach.
We match every replacement to your home's real heating and cooling load rather than defaulting to whatever's on the truck. Installations get done to code: sealed duct connections, correct line sets, proper condensate handling, clean electrical work. Most installs are completed in a single day with minimal disruption.
Our team believes in keeping systems alive with inexpensive seasonal care. If you want years more from your current equipment, our spring and fall maintenance visits handle the checks that actually extend equipment life. It's that simple.
