AC Repair in Opelika, AL
Licensed HVAC professionals serving Opelika, Auburn, and Lee County for more than 40 years. HVAC License #15068. Headquartered in Opelika.
Opelika homeowners calling for AC repair are almost always facing one of two frustrating situations: a system that stopped working without warning, or a system that was already repaired once and is having problems again.
Caswell Heating Air has diagnosed and repaired AC systems throughout Opelika and Lee County for more than 40 years. Our diagnostic process uses measurements, not guesswork. Voltage, amperage, refrigerant pressures, and temperature differential are all recorded before any repair is proposed, so the root cause is identified rather than just the most obvious component to swap.

What Caswell Heating Air Diagnoses and Repairs in Opelika
Opelika’s hot, humid summers create a predictable set of AC failure patterns. Our technicians have seen all of them across more than four decades of service in Lee County.
Failed run capacitor. The single most common no-cooling call in Alabama during summer. The run capacitor powers the compressor and condenser fan motor through every startup cycle. In Opelika’s afternoon heat, where ambient temperatures at the outdoor unit regularly exceed 100 degrees Fahrenheit, capacitors degrade faster than their ratings predict. A capacitor that reads more than 10 percent below its rated microfarad value cannot reliably start the compressor and will fail during the next heat advisory if not replaced. We test the capacitor with a capacitance meter on every service call, not just when it is suspected.
Refrigerant charge deficit. A system that runs but does not cool to setpoint, with ice forming on the refrigerant lines or indoor coil, has lost refrigerant from a leak. Adding charge without finding the source of the leak is a temporary fix. We use an electronic refrigerant leak detector to locate the leak before any charge is added, so the repair lasts.
Dirty condenser coil. Opelika’s combination of pollen, dust, and cottonwood creates significant condenser coil fouling that restricts heat rejection from the outdoor unit. A coil that cannot reject heat efficiently raises the high-side refrigerant pressure, forces the compressor to work beyond its design parameters, and eventually trips the high-pressure safety cutout. Coil cleaning is part of every maintenance visit and is performed during repair calls where coil blockage is identified as contributing to the failure.
Tripped the safety cutout. A system that will not restart after shutting off has usually tripped an internal safety, high-pressure, low-pressure, or thermal, due to an underlying condition. We identify why the safety tripped before resetting it, so the repair addresses the cause rather than the symptom.
Contactor failure. The high-voltage contactor switch connects utility power to the compressor and outdoor fan motor. Contactors that have developed burned contact surfaces cause arcing and intermittent operation. We test the contactor under load and replace it with a properly rated replacement when contact pitting or voltage drop indicates failure.
Tori Mejia called Caswell Heating Air when her system was underperforming and described a technician who found the actual problem efficiently and delivered a result no competing quote had matched:
“Josh quickly identified our issue and saved us tons of money compared to other competitors. Thank you, Josh and team, for the friendly and amazing service!”
Our AC Repair Process in Opelika
Step 1: Symptom Review and System Assessment. The technician notes the equipment make, model, age, and service history, then reviews with the homeowner when the problem started, what the system is doing, and whether anything changed before the failure. This context shapes where the diagnostic begins.
Step 2: Electrical and Refrigerant Measurement. A digital multimeter measures voltage at the disconnect, amperage draw at the compressor and fan motor, and capacitance at the run capacitors. A refrigerant manifold gauge set measures high-side and low-side pressures against the manufacturer’s specification for the current outdoor temperature. These measurements identify whether the fault is electrical, mechanical, or refrigerant-related before any disassembly begins.
Step 3: Written Estimate Before Any Work. The technician explains the finding in plain language and provides a written estimate before any repair is approved. No work begins without written authorization. For situations where multiple issues are found, the technician distinguishes what is immediately necessary from what can be deferred, so the homeowner can decide with full information.
Step 4: Repair. Common repair parts, run capacitors, contactors, start capacitors, and common electrical components, are carried on service vehicles for same-visit resolution. For parts requiring sourcing, the technician advises on the timeline and discusses interim options.
Step 5: Performance Verification See the section below.
Performance Verification After AC Repair
Before closing any repair call, Caswell Heating Air re-tests the system under operating load. Refrigerant pressures are re-measured against specification. Amperage draw on the compressor is confirmed against the nameplate rating. Temperature differential between return and supply air is measured to confirm the system is producing adequate cooling output.
Voltage at the disconnect and contactor is verified under load. All post-repair measurements are documented and you receive a written service record, the repair performed, parts installed, measurements before and after, and warranty terms, before the technician leaves.

Frequently Asked Questions About AC Repair in Opelika, AL
What is the most common AC repair in Opelika?
Run capacitor replacement. The capacitor powers the compressor and outdoor fan motor through every startup cycle, and Alabama’s summer heat accelerates capacitor degradation significantly. A failed capacitor is usually the cause when a system hums but will not start, or when the outdoor unit is not running at all.
Why does my AC keep having the same problem after repair?
Recurring failures after repair usually mean the root cause was not identified. A capacitor that fails early may indicate the compressor is drawing more current than normal, stressing the capacitor on every cycle. A refrigerant system that needs recharge repeatedly has a leak that was not located and sealed. Caswell’s diagnostic process specifically looks for the cause behind the symptom before proposing a repair.
Does Caswell Heating Air offer emergency AC repair in Opelika?
Yes. 24-hour emergency HVAC service is available for urgent situations.
Will I receive a written estimate before any repair begins?
Yes. A written estimate covering the repair, parts, and labor is provided before any work is approved. No repair begins without your written authorization.
How long does an AC repair take?
Most common repairs — capacitor replacement, contactor replacement, refrigerant recharge with leak repair — are completed in a single visit. Complex diagnostics involving intermittent faults or multiple component failures may take longer. The technician provides a realistic timeline after the initial assessment.
