AC Repair Services We Provide Across East Alabama

• Cooling and airflow problems. Warm air from the vents, weak airflow or rooms that never cool are among the most common calls we get. The cause can be as simple as a clogged filter or as involved as a failing blower motor, so testing should come before any part is replaced.
• Refrigerant leaks and low charge. Air conditioners do not use up refrigerant. If the charge is low, there is a leak somewhere, and a good repair locates it instead of just adding more.
• Electrical failures. Capacitors, contactors, relays and control boards control when your compressor and fans start. When one fails, the unit may hum, click or not start at all.
• Compressor and fan motor problems. The compressor and the motors are the hardest working parts of the system. Testing shows their condition and what a repair would involve.
• Frozen coils and water leaks. Ice on the indoor coil or water near the air handler usually points to an airflow, charge or drain problem. Finding the root cause is what keeps it from returning the following week.
• Thermostat and control issues. A system that will not respond, short cycles or reads the wrong temperature may have a control problem rather than an equipment problem.
• Heat pump repair in cooling mode. Heat pumps cool the way an air conditioner does, so cooling-mode repairs follow the same diagnostic logic.

Signs Your AC Needs Repair

Catching a problem early often keeps a small repair from becoming a large one. Call us if you notice any of these.

• Warm air from the vents while the outdoor unit runs
• A system that turns on and off in short bursts
• Ice on the refrigerant lines or the indoor coil
• Water around the indoor unit or a musty smell near the vents
• Rattling, buzzing, squealing or clicking from the indoor or outdoor unit
• A breaker that trips when the system starts
• Rooms that are hot or damp while the thermostat reads normal

If you are not sure what you are seeing, our guide to common AC problems and how professionals fix them is a useful place to compare symptoms.

What a Good AC Diagnosis Involves

A diagnosis begins with your account of what you noticed and when it started. From there, a technician should inspect the system, check the electrical components, measure airflow and test the refrigerant side. Expect the findings in plain language with the repair options laid out.

What happens next is your decision, so approve work only when the options make sense to you.

Repair or Replace? How to Decide

Every repair question eventually becomes a repair versus replace question. These are the factors worth weighing.

• What failed. A capacitor or contactor is a small repair. A failed compressor or a leaking coil is a larger decision.
• The age and type of refrigerant. Older systems use refrigerants that are being phased out, which affects how repairs and recharges work. The next section explains why.
• How the system performs overall. If the house stays comfortable and the failed part is isolated, repair usually makes sense. If the system struggles to keep up or has needed repeated repairs, replacement may be the better path.
• Your plans for the home. How long you intend to stay matters as much as what the system needs today.

Ask for the information to compare both options. If replacement makes sense, ask about the choices, and know that 100% financing is available. Details are on our financing page.

How the Refrigerant Phasedown Affects AC Repair in East Alabama

Refrigerant rules are changing, and that affects what a repair means for an older system. The U.S. Environmental Protection Agency’s Technology Transitions program sets limits on hydrofluorocarbons, or HFCs, in specific products. For new residential and light commercial air conditioners and heat pumps, the limit took effect on January 1, 2025, and it requires refrigerants with a global warming potential of 700 or lower.

That is the second big transition homeowners have seen. R-22, the refrigerant in many older systems, has been phased out of new production under federal ozone rules, so servicing those systems depends on limited recycled and reclaimed supply. R-410A, which replaced it in newer systems, is now giving way to lower-impact refrigerants, commonly called A2L refrigerants, in new equipment.

For you, this has practical effects. An R-22 system that leaks needs a serious conversation, because repeated recharges are a temporary measure at best. An R-410A system can still be repaired and serviced, but new equipment will use a different refrigerant, and the parts are not interchangeable. When an older system is evaluated, ask which refrigerant it uses, what the repair involves and how that shapes the repair or replace decision.

What Customers Say

Careful Repair and a Full System Check

SL Knight had a damaged part in an AC system and needed it repaired. The technician, Zeke, handled the repair and then checked the whole system rather than stopping at the one part.

“Great service. Zeke was very efficient in repairing the damaged part and also thoroughly checked that the system was running as it should be after the repair.”

A repair is not finished until the system runs correctly, and that follow-through is worth expecting.

A Knowledgeable Technician on Short Notice

Nathan Short asked Caswell to inspect his AC and help out. He described how the technician handled it.

“Thomas the technician was very knowledgeable”

Leaving with a clear understanding of what is wrong and what comes next is a fair expectation.

AC Repair in East Alabama: Frequently Asked Questions

Why is my AC running but not cooling?

Common causes include a dirty filter, low refrigerant from a leak, a failed capacitor or a frozen indoor coil. Because the causes are so different, the fix depends on testing, not guessing. A technician can check airflow, electrical parts and the refrigerant side to find out.

How do I know if my AC uses R-22 or R-410A?

The refrigerant type is listed on the nameplate on the outdoor unit. If you are unsure, a technician can read it for you during a visit. It matters because it affects how repairs and recharges are handled.

Is it worth repairing an older air conditioner?

It can be, if the failed part is isolated and the rest of the system is in good shape. If the system has needed repeated repairs or struggles to keep up, replacement may serve you better. Ask for both options so you can decide.
