Quick Answer
If your air conditioner in Dacula won't cool, is leaking, or is making unusual noise, Hixon's factory-trained technicians run a full mechanical and electrical diagnostic on the actual unit — compressor, capacitor, contactor, coils, and refrigerant levels — to pinpoint the failure instead of guessing.
There's a difference between "AC repair" as a general service and truly understanding the equipment sitting outside your home. Hixon Heating & Air Conditioning has been Gwinnett County's choice for air conditioner repair since 1993, and our technicians specialize in the mechanical and electrical systems that make up your specific unit — condenser coils, compressors, capacitors, contactors, refrigerant lines, and control boards.
A lot of AC problems in Dacula homes trace back to the same handful of components wearing out under the summer heat load. Rather than swap parts on a guess, we use manufacturer-specified diagnostic procedures to isolate exactly which component has failed, so the repair we recommend is the repair your unit actually needs.
Signs Your Air Conditioner Unit Needs a Professional Look
Signs Your Air Conditioner Unit Needs a Professional Look
- The outdoor condenser unit runs constantly but the house never cools
- The compressor hums but the fan doesn't spin
- Ice forming on the refrigerant lines or indoor coil
- A burning smell near the outdoor unit or electrical panel
- The unit trips the breaker repeatedly
- Refrigerant lines are visibly damp or oily (a sign of a leak)
Our Process
How We Diagnose Your Air Conditioner
1. Electrical Testing
We test capacitors, contactors, relays, and control-board wiring with calibrated meters rather than visual inspection alone, since many electrical failures aren't visible to the eye.
2. Refrigerant & Airflow Check
We measure refrigerant pressures against manufacturer specifications and inspect airflow across both the indoor and outdoor coils, since a dirty coil is one of the most common — and most overlooked — causes of poor cooling.
3. Clear Repair Recommendation
You get a plain-English explanation of what failed, why it failed, and whether a repair or a replacement makes more financial sense for a unit of your system's age.

Frequently Asked Questions
Air Conditioner Repair & Diagnostics in Dacula, GA FAQs
Why does my air conditioner run but not cool the house?
This is most often caused by a refrigerant leak, a dirty evaporator or condenser coil, a failing compressor, or a duct problem restricting airflow. A full diagnostic identifies which of these applies to your unit.
Is it worth repairing an older air conditioner unit?
It depends on the age of the unit, the cost of the specific repair, and your energy bills. Our technicians will give you an honest comparison of repair versus replacement cost so you can make the right call for your budget.
How long does an air conditioner diagnostic take?
Most diagnostics are completed within the same visit, typically 30–60 minutes, and you'll have a written repair recommendation before we leave.
