Summer in the Birmingham area is long, hot, and humid, and when your air conditioner stops keeping up, the house can become uncomfortable fast. One Source Heating, Cooling, Plumbing & Electrical provides AC repair in Birmingham, AL for central air conditioners, heat pumps, and ductless systems. Our NATE-certified technicians diagnose the actual cause of the problem, explain the repair options and price before any work begins, and carry stocked trucks so most repairs can be completed the same day.
One Source has served Birmingham homeowners since 1996. We never use subcontractors, and repair service is available 24/7 when your system fails at the worst possible time.
Signs Your Air Conditioner Needs Repair
Some AC problems are obvious, like a system that will not turn on. Others start small and get worse. Call for service if you notice:
- Warm or lukewarm air coming from the vents
- The system runs constantly but the house never reaches the set temperature
- Weak airflow from some or all vents
- Ice on the refrigerant lines or the indoor coil
- Water leaking around the indoor unit or a full drain pan
- Buzzing, clicking, grinding, or squealing noises
- The outdoor unit hums but the fan does not spin
- The system turns on and off in short cycles
- The breaker for the AC trips repeatedly
- Higher-than-normal humidity indoors, or a musty smell
- Electric bills that rise without a change in use
Catching these signs early often means a smaller repair and less strain on the rest of the system.
Common AC Problems We Repair in Birmingham
Failed Capacitors and Contactors
Capacitors give the compressor and fan motors the boost they need to start. They are one of the most common parts to fail during long stretches of summer heat. A failing capacitor often shows up as an outdoor unit that hums but will not start, or a fan that does not spin.
Refrigerant Leaks
Air conditioners do not use up refrigerant. If the charge is low, there is a leak. Signs include warm air, ice on the lines or coil, and a system that runs for long periods without cooling the home. The right fix is finding and repairing the leak, not repeatedly adding refrigerant. Learn more about our AC refrigerant leak repair and recharge service.
Frozen Evaporator Coils
A frozen coil usually points to restricted airflow, such as a clogged filter, blocked return, or failing blower, or to low refrigerant. If you see ice, turn the cooling off and run the fan to let it thaw, then call for service so the underlying cause can be corrected.
Clogged Condensate Drains
Birmingham’s humidity means air conditioners remove a lot of moisture from the air. That water drains through a condensate line that can clog with algae and debris. A clogged drain can trigger a safety switch that shuts the system down or cause water damage near the indoor unit.
Dirty Coils and Restricted Airflow
Spring pollen, grass clippings, and debris can coat the outdoor condenser coil, while dirty filters and ductwork problems restrict airflow indoors. Both make the system work harder, cool less, and cost more to run.
Fan and Blower Motor Failures
The outdoor fan moves heat away from the condenser, and the indoor blower moves cooled air through your ducts. When either motor fails, cooling drops off quickly.
Thermostat and Electrical Problems
Loose wiring, failed relays, tripped breakers, and thermostat issues can all look like a major AC failure. A proper diagnosis keeps you from paying for parts you do not need.
Compressor Problems
The compressor is the heart of the system. Compressor problems are less common than other failures, but they are among the most significant. When the compressor fails on an older system, we will help you compare a repair with replacement.
What to Check Before You Call
A few quick checks can sometimes restore cooling or help us diagnose the problem faster:
- Thermostat: Confirm it is set to cool, the set temperature is below the room temperature, and the batteries are good.
- Breakers: Check the breakers for the indoor and outdoor units. If a breaker trips again after resetting, leave it off and call for service.
- Air filter: A clogged filter can reduce airflow and cause the coil to freeze.
- Outdoor unit: Make sure it is clear of leaves, grass, and debris.
- Drain line: Look for water around the indoor unit or a full drain pan.
Avoid opening electrical panels on the equipment or adding refrigerant yourself. Those repairs require a trained, EPA-certified technician.
Our AC Repair Process
1. We Listen to What You Are Experiencing
We start with the symptoms, when they began, and any recent changes, which helps narrow down the cause.
2. We Diagnose the System
Our technician inspects the electrical components, refrigerant pressures, airflow, coils, drain, and controls to find the actual cause of the problem.
3. We Explain Your Options and Price
You get a clear explanation of what failed and the repair cost before any work begins. If replacement deserves a look, we will explain why.
4. We Complete the Repair
Because our trucks are stocked with common parts, most repairs can be finished on the first visit.
5. We Test the System
We confirm the system is cooling properly, the airflow is balanced, and there are no other issues that need attention, and we note anything you should keep an eye on.
Repair or Replace Your Air Conditioner?
Repair is usually the right choice when the system is in good overall condition and the failure involves a single component. Replacement may be worth considering when:
- The system is roughly 12 to 15 years old or older
- It uses R-22 refrigerant, which is no longer produced and is expensive to obtain
- The compressor or coil has failed on an aging system
- Repairs are becoming frequent
- Energy bills keep climbing or the home never feels comfortable
We will give you an honest recommendation and the information you need to compare the cost of a repair with the long-term value of a new system. If replacement makes more sense, learn about air conditioner replacement in Birmingham. Financing is available for larger repairs and replacements through our financing options.
What Affects the Cost of AC Repair?
- The part that failed and its availability
- The type of system, such as central AC, heat pump, or ductless mini-split
- Whether refrigerant work or leak repair is needed
- Access to the indoor and outdoor equipment
- Whether the repair is an after-hours emergency
We provide the price before work begins, so there are no surprises.
Emergency AC Repair in Birmingham
When the air conditioning goes out on a 95-degree afternoon, waiting days for service is not an option, especially for infants, older adults, or anyone with health concerns. One Source provides 24/7 repair service. Learn more about our 24/7 emergency AC service.
Prevent Breakdowns With Regular Maintenance
Many summer breakdowns start as small problems that routine maintenance would have caught, such as a weak capacitor, a dirty coil, or a partially clogged drain. Annual air conditioning maintenance helps your system run more efficiently, reduces the chance of a breakdown during peak heat, and can extend the life of the equipment. Ask about our HVAC maintenance plans.

Frequently Asked Questions About AC Repair in Birmingham
Why is my AC running but not cooling?
Common causes include a dirty air filter, a frozen evaporator coil, low refrigerant from a leak, a dirty outdoor coil, or a failed capacitor or fan motor. A technician can test the system to find the exact cause.
Why is my outdoor AC unit humming but not running?
A humming outdoor unit that does not start often has a failed capacitor or a stuck motor. Turn the system off to avoid damaging the compressor and call for service.
How long does AC repair take?
Many common repairs, such as replacing a capacitor, contactor, or motor, can be completed in a single visit because our trucks carry common parts. Leak repairs and major components can take longer.
Is it worth repairing an old air conditioner?
It depends on the age of the system, the repair cost, and its overall condition. If the system is older, uses R-22 refrigerant, or needs a major component, replacement is often the better long-term value.
Why is water leaking from my air conditioner?
Leaks usually come from a clogged condensate drain line, a cracked drain pan, or a frozen coil that is melting. Turn the system off and call for service to prevent water damage.
