When your air conditioner quits in July and the thermostat reads 84 degrees at 9 p.m., you don’t need a callback window. You need a technician who picks up the phone, gives you a written price before the truck rolls, and stands behind the work for a full year. That’s how Dalton Heating & Air Alpharetta has operated since 2003 under The Garrison Standard, and it’s why homeowners from Crabapple to Windward keep our number saved. Marco Benitez leads our Alpharetta team, and every technician who shows up at your door is background-checked, uniformed, and factory-trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Most AC repairs in Alpharetta run $150 to $650 depending on the part that failed, and we can usually have someone at your house the same day you call. Reach us at (229) 537-2086 any hour, any day, and a live person answers.
How Much Does AC Repair Cost in Alpharetta?
A typical AC repair in Alpharetta runs $150 – $650 depending on what failed. The most common job we do is a capacitor replacement, which usually lands in the $180 – $320 range including the part and labor. A refrigerant recharge (topping off the cooling fluid your system needs to reach set temperature) typically runs $250 – $500, though that assumes no major leak repair. Here’s what that looks like in practice:
- Capacitor replacement: $180 – $320
- Condensate drain line clearing: $150 – $250
- Refrigerant recharge: $250 – $500
- Contactor or relay replacement: $190 – $350
- Compressor replacement: $1,800 – $3,200 (we’ll always quote a full replacement comparison before you decide)
Two things move the needle on price: the part that failed and whether your system uses R-410A or the older R-22 refrigerant, which has gotten expensive as production phased out. The way to avoid overpaying is simple: get the price in writing before any work starts. At Dalton Heating & Air Alpharetta, that’s not an option or an upgrade, it’s the only way we quote. Your estimate includes the diagnosis, the exact part cost, and the labor. Call (229) 537-2086 for a free estimate with no obligation.
Styles & brands we work with
AC Maintenance
AC Maintenance is the scheduled service that keeps your system from breaking down during the worst stretch of a Georgia summer. You need it twice a year here in Alpharetta, ideally in early spring before the heat settles in and again in fall before you switch the thermostat to heat. Dalton Heating & Air Alpharetta performs a 21-point maintenance inspection for $80 – $200 per visit, and the price is in writing before we start, same as every job we do.
What’s included at every visit
We check refrigerant pressure, test all electrical connections and capacitors, clean or replace the air filter, clear the condensate drain line, and measure the temperature drop across the coil. You get a written report of what we found, what we fixed, and what might fail next. No upsell pressure; our technicians aren’t paid on what they sell.
Why clean coils matter in the Atlanta metro
This part of Georgia gets heavy pollen in March and April and relentless humidity through September. A coil packed with pollen and cottonwood fluff forces the compressor to run hotter and longer, which is why so many capacitor failures in Alpharetta happen in July and August. A $120 maintenance visit beats a $300 part failure every time.
AC Service
AC Service is the full spectrum of diagnosis, repair, and follow-up work that keeps a residential cooling system running, not just the individual parts that break. You need it when the system is making noise it never made before, short-cycling, leaking water into the overflow pan, or running constantly without reaching temperature. A service call at Dalton Heating & Air Alpharetta starts at $150 – $650 depending on what we find, and the price is in writing before any work begins.
How diagnosis works on an older system
If your air handler or condenser is 10 years old or more, the problem is rarely one clean failure. It’s usually cumulative: a weak run capacitor, a pitted contactor, a partially clogged TXV. Our technicians test the whole circuit, not just the part that tripped, so you’re not paying for the same repair twice.
The written report you keep
Every AC Service call ends with a written report showing the measured pressures, amp draws, and temperature stats from your unit, along with what we replaced and what we recommend. You can hold that report up against any quote from another company and compare line items honestly. That’s the point.
AC Unit Repair
AC Unit Repair is the hands-on repair work on the physical components of your condenser, air handler, or packaged unit, not just the diagnostics around it. You need it when a specific part has been identified and the fix is straightforward: a new fan motor, a contactor, a start kit. Dalton Heating & Air Alpharetta completes most AC unit repairs in one visit, with parts on the truck and pricing set before the work starts, typically $150 – $650.
Common component failures we see in Alpharetta
In Alpharetta specifically, we see a lot of contactor failures in older subdivisions like Kimball Bridge and Nesbit Ferry where homes went up in the nineties and early two-thousands. A contactor is the switch that starts the compressor; when the points arc and pit, the unit won’t start at all or chatters when it tries. It’s a simple (but hard-failing) $100 part that stops a $4,000 system dead.
Straight talk on repair vs. replace
We’ll never push you toward a new system to make a sales number. Our rule is this: if the compressor or evaporator coil has failed on a unit that’s older than 12 years, we’ll show you both options with honest numbers for each. If the repair is a capacitor, a fan motor, or a control board, replacing the whole unit is the wrong call and we’ll say so.
AC Capacitor Replacement
AC Capacitor Replacement is swapping out the small cylinder-shaped device that gives your compressor and fan motor the electrical jolt they need to start. When they fail, your outside unit will hum but not start, or the fan will spin slowly, or the system will trip its own breaker. In Alpharetta, our capacitor replacements average $180 – $320 including the part, and most get done the same day you call.
The heat is what kills capacitors
Capacitors degrade with heat exposure, and Alpharetta attic temperatures in July regularly hit 130 degrees. A capacitor that tests fine in April can be on its last legs by August. When we replace one, we check the one next to it too because many outside units have two: one for the compressor and one for the fan, and they fail in pairs.
Warning signs before total failure
You’ll usually get a warning: a clicking sound from the outside unit, a fan that takes a few seconds to spin up, or cooling that seems weaker by late afternoon. If you’re hearing or seeing any of that, call (229) 537-2086 now. Replacing a capacitor early is a $200 job; waiting until it fails completely on a 95-degree Saturday tends to turn into a more expensive repair.
AC Recharge
AC Recharge is adding refrigerant to a system that has lost charge, which is the cooling fluid your system needs to reach set temperature. Most Alpharetta homes with AC recharge needs are running R-410A systems from the 2000s and 2010s; older units on R-22 face supply costs that have climbed sharply. A recharge through Dalton Heating & Air Alpharetta runs $250 – $500, but the honest truth is this: if your system is low, it’s low because it leaked, and a recharge without finding the leak is a temporary fix.
Why a simple top-off isn’t always the answer
Refrigerant doesn’t burn off like fuel; it cycles in a sealed loop. If pressures are down, there’s a leak somewhere: a schrader valve, a braze joint, a coil with a pinhole. Our technicians use electronic leak detectors and UV dye to find where the charge is escaping before we add anything back. On a 15-year-old unit, we’ll show you the math on a full system replacement versus an open-ended search for a coil leak.
Fixed pricing and no surprises
Some companies quote a low recharge price and then charge by the pound once they’re on site. We don’t work that way. You’ll know the total before we open a service valve, and the price we write is the price you pay. Call (229) 537-2086 if you’ve been told you need a recharge and want a second opinion with the numbers in hand.
Emergency AC Repair
Emergency AC Repair is a repair you can’t reasonably wait until morning for: a dead system on a 95-degree day with a baby or elderly family member in the house, or a unit that’s tripped its breaker repeatedly and you’re worried about the wiring. Dalton Heating & Air Alpharetta staffs a live phone line 24 hours a day, 7 days a week, and our emergency repairs fall in the same $150 – $650 range with the same written pricing, no overtime multiplier.
The live phone standard
A lot of companies route after-hours calls to an answering service that takes a message and says a dispatcher will call back. We don’t. When you call (229) 537-2086 at 11 p.m., a person answers who can tell you what to shut off, what to check, and when a technician will be there.
What to do before we arrive
Check your breakers first: a tripped breaker is free to fix and sometimes that’s all it is. If the breaker trips again immediately, stop resetting it and call us. Don’t open the outside unit and start probing contacts yourself; high-voltage capacitors hold a charge even with the power off and can cause serious injury. That’s a job for a trained tech with the right meter and the right gloves.
AC Not Blowing Cold Air
AC Not Blowing Cold Air is the single most common call we get during Alpharetta summers, and it has six or seven usual causes: a frozen evaporator coil, a failed capacitor, a clogged filter, a refrigerant leak, a bad thermostat, or a compressor that’s given up. Most of those causes fall in the $150 – $650 range to fix, except a true compressor failure, which we’ll always quote with a full replacement option alongside.
The five-minute check before you call
Look at the air filter: a clogged filter chokes airflow, the coil ices over, and the unit blows warm. Check the thermostat is on COOL and set below room temp. Look at the outside unit while it’s running: is the fan turning, or is it just humming? Those details mean something to us, so note them before you call (229) 537-2086.
Why icing is more common in humid climates
Georgia’s humidity means your evaporator coil pulls gallons of moisture out of the air every day. If the condensate drain line clogs with algae (which happens fast in warm, wet conditions), the overflow switch may trip or the coil may ice over. In Alpharetta specifically, we clear more clogged drain lines in June through August than any other single repair. It’s usually a fast, inexpensive fix done the same visit.

AfterBrands We Service
We’re factory-trained to service all nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That training isn’t a logo on our website; it means our technicians have taken the manufacturer courses, know the common failure points, and carry the right parts on the truck.
On Lennox systems, we’ve done steady repair work on the XC and XP series across Alpharetta and see the most trouble with the two-stage compressor kits in systems 8-12 years old. Goodman units are straightforward designs, but they eat capacitors in Georgia heat just like everything else; we stock OEM and aftermarket-start components for them. Rheem and York systems show up frequently in homes around Windward and Kimball Bridge, and we’re familiar with their specific control-board fault codes. If you’ve got a Goodman, a Lennox, a Rheem, or any other make, we can help.
Signs You Need a Pro Right Now
- Warm air from every vent while the outside unit’s running: this means the compressor is doing its job but the heat isn’t leaving the house, which points to a refrigerant leak or a failed reversing valve. Both are fixable, but running the system this way makes the problem worse every hour.
- The outside unit is humming but the fan isn’t spinning: that’s a capacitor that’s lost its capacitance or a fan motor that’s seized. Shut the system off at the thermostat and the breaker; the compressor can overheat and damage itself inside twenty minutes.
- Water is pooling around the indoor air handler: the condensate drain line is clogged and water is backing up toward your blower or your drywall. In a humid Alpharetta house, this can dump gallons of water in a day, and the cleanup is far more expensive than the $150 – $250 drain clearing.
- The system runs constantly but won’t reach setpoint by afternoon: your system is losing capacity, which usually means low refrigerant or dirty coils, or it’s undersized for the heat load of a second-story addition. A technician should measure the temperature difference across the coil to know which one it is.
- You smell something acrid or metallic from a vent: that’s often a seized blower motor or a failing run capacitor overheating its own casing. Turn the system off and call us. Electrical problems carry a fire risk and shouldn’t wait.
Our Process, Step by Step
- 1
We pick up the phone. Call (229) 537-2086 and a live operator answers, day or night. They’ll get your address, the symptoms you’re seeing, and the best window for us to arrive, and they’ll confirm the price of the service call itself before we even dispatch.
