The short answer
There is no honest single number for AC repair in Kennesaw, GA, which is why we do not publish a price list. The cost depends on what failed, which refrigerant your system uses, how hard the unit is to reach and when the work happens.
Small part swaps such as a capacitor or a cleared drain line sit at the low end. Fan motors and leak repairs fall in the middle. Compressors and coils are the expensive end. You get the price before any work starts.
Why We Do Not Publish a Price List
Plenty of pages that answer this question post a chart of prices. We chose not to, for three reasons.
A symptom is not a diagnosis. Blowing warm air can be a failed capacitor, a refrigerant leak or a dead compressor. Those are three very different jobs, and a price given before anyone tests the system is a guess.
The contractor sets the price. Hooten Air Pros answers the phone 24/7 and dispatches independent HVAC contractors. Every HVAC contractor we send is licensed and insured in Georgia. A number on our website would be a promise we cannot keep.
Prices move. Refrigerant, parts and labor costs change from season to season, and a chart goes stale the day it is published.
What we can promise is the process: the technician diagnoses the problem, explains it, and gives you the price before any work starts. You decide whether to go ahead.
AC Repairs From Smallest to Largest
Even without numbers, repairs fall into clear tiers. Knowing which tier your problem sits in helps you judge the quote.
Smaller repairs: part swaps and clearing
- Run capacitor: the most common summer failure. The outdoor unit hums but the fan or compressor will not start.
- Contactor: the switch that turns the outdoor unit on. Pitted contacts or insects stop it.
- Clogged condensate drain or tripped float switch.
- Thermostat wiring, a blown low-voltage fuse or a loose connection.
These are usually finished in one visit with parts on the truck.
Mid-range repairs: motors and leaks
- Outdoor fan motor or indoor blower motor. Variable-speed blower motors cost more than standard ones.
- Refrigerant leak search, repair and recharge. The cost depends on where the leak is and which refrigerant the system uses.
Major repairs: the ones that raise the replacement question
- Compressor: the most expensive single part in the system.
- Evaporator or condenser coil: refrigerant recovery, brazing, vacuum and recharge.
- Several failures at once on an older system.

Your Refrigerant Type Can Change Everything
The rating plate on the outdoor unit names the refrigerant, and that one line can change the cost of a leak repair more than anything else.
- R-22: common in Kennesaw homes built through the 2000s. U.S. production and import ended January 1, 2020, so the only supply is reclaimed or stockpiled. It is scarce and expensive, and a large R-22 recharge is often the moment owners decide to replace.
- R-410A: the standard in systems installed from about 2010 until recently. It remains fully serviceable.
- R-454B or R-32: used in new split systems since the January 1, 2025 transition to lower-GWP refrigerants. These newer systems are the most likely to still have manufacturer parts coverage.
Other Things That Push the Price Up or Down
Attic access in two-story homes
Many two-story homes in Kennesaw and Woodstock's Towne Lake area have the upstairs air handler in the attic. A blower motor or coil job there means hauling parts up pull-down stairs and working in a cramped space that can be far hotter than outdoors in July. Tight clearances add labor time.
Nights, weekends and holidays
After-hours work usually costs more because contractors pay technicians to be on call. If the house is safe and the problem can wait, ask whether a daytime visit changes the price. If it cannot wait, that is what emergency AC repair is for.
Warranty status of the parts
Many manufacturers offer longer parts coverage when equipment was registered after installation. A covered part lowers the bill, though labor and refrigerant are usually billed separately. Have the model and serial numbers ready.
System age
On a 15-year-old unit, a technician may find a second worn part while fixing the first. A good one tells you so you can decide what to fix now.
How to Read an AC Repair Quote
A useful quote is written, specific and separates the pieces. Look for:
- The diagnosis in plain words: what failed and how it was confirmed.
- The part by name: "replace dual run capacitor," not "electrical repair."
- Refrigerant details: the type, and whether the leak is being repaired or the system is only being topped off.
- Labor and any diagnostic or after-hours charge, shown as separate lines.
- Coverage afterward: the contractor's labor warranty, if any, and the manufacturer's coverage on the part.
A quote that bundles everything into one line is harder to compare and harder to question.
Questions to Ask Before You Approve the Work
- Is the diagnostic charge applied to the repair if I go ahead?
- What happens if I wait? Is this a safety issue or a comfort issue?
- Is the part under manufacturer warranty, and will you handle the claim?
- If it is a leak, where is it, and can it be repaired rather than just recharged?
- Did you see anything else close to failing?
- At this system's age, would you put this money into a repair?
A technician confident in the diagnosis will answer these without pressure. If you feel rushed, ask for the quote in writing and take a little time.
How to Keep Repairs in the Smaller Tier
The cheapest repair is the one that never becomes an emergency. Many small-tier failures give warning. A capacitor that tests weak in April often fails in July. A drain line that is half clogged in spring overflows in August humidity. Pollen-matted outdoor coils make the compressor work harder all summer.
A spring HVAC maintenance visit catches those things while they are minor and before the busiest weeks, when everyone in Cobb County wants a technician the same afternoon. Between visits, change filters often in pollen season and keep the outdoor unit clear.
From the Field: How Contractors Actually Price an AC Repair
Knowing how the number is built makes it easier to judge whether it is fair.
Flat-rate versus time and materials
Many HVAC contractors price from a flat-rate book: each repair has a set price that already includes the part, labor and a typical amount of time, so an attic job does not cost more just because it ran long. Others bill time and materials: an hourly labor rate plus parts. Neither is wrong. Ask which method the contractor uses, because it changes how you compare two quotes.
Line items that surprise people
- Refrigerant is usually priced by the pound. A leaking system that needs several pounds of R-22 costs far more than the same top-off on R-410A.
- Warranty work is rarely free. A manufacturer warranty usually covers the part, not the labor to install it.
- The diagnostic or service-call fee may or may not be credited toward the repair. Ask before dispatch.
Why online cost ranges mislead
Cost guides average national or metro-wide data across every kind of system. They cannot see that your capacitor is in an outdoor unit you can walk up to or that your coil is in a 130-degree Kennesaw attic. Use them for a rough sense of scale, then rely on a written price for your system.
Get a Real Price for Your System
If your AC is acting up, call Hooten Air Pros at (321) 478-0693, any hour. Tell the dispatcher what you are seeing and, if you know it, the refrigerant on the outdoor unit's label. We send the nearest available licensed contractor for AC repair in Kennesaw, and you get a written price before work begins.
Common Questions
Is it cheaper to fix my AC in spring than in July?
The repair itself is usually priced the same, but spring gives you choices. You can book a weekday appointment, compare quotes and plan a replacement on your own schedule. In July, failures tend to happen on hot evenings and weekends, when after-hours rates may apply and every contractor in Cobb County is busy.
Why does an R-22 recharge cost so much?
No new R-22 has been produced or imported in the U.S. since January 1, 2020. Every pound now comes from reclaimed or stockpiled supply, and that supply keeps shrinking. A system low on refrigerant also has a leak, so recharging without a repair means paying again later. That is why many R-22 owners put the money toward replacement.
Should I get a second opinion on a major repair?
For a compressor, a coil or any repair that approaches the cost of replacement, a second opinion is reasonable. Ask the first technician to write down the diagnosis and the readings taken, such as pressures, temperatures and electrical tests. That record helps the second technician confirm the problem quickly instead of starting from zero.
What is a diagnostic fee?
Many contractors charge a fee to come out, test the system and find the problem. Some apply it to the repair if you approve the work. Ask about it when you call so there are no surprises. The diagnosis has real value: it means the quote you get is for the actual failure, not a guess.
