AC Maintenance in Opelika, AL
Licensed HVAC professionals serving Opelika, Auburn, and Lee County for more than 40 years. HVAC License #15068.
Most Opelika homeowners skip a year of AC maintenance because nothing seems wrong. The system runs, the air feels cool enough, and scheduling a tune-up when nothing is broken does not feel urgent. The problem is that the components most likely to cause a breakdown, run capacitors, contactors, and refrigerant charge levels, degrade gradually and silently. They do not announce themselves until the moment they fail, and that moment typically arrives on the hottest afternoon of an Alabama summer.
Caswell Heating Air has serviced HVAC systems throughout Opelika and Lee County for more than 40 years. A tune-up from one of our licensed technicians shows you exactly what is happening inside your system, before it becomes an emergency.

What Deferred Maintenance Looks Like in Opelika
Matt Knitter had not scheduled a tune-up in a few years when he called Caswell Heating Air. Technician Trey Bradford came out, performed the tune-up, and showed Matt pictures of everything he found in the attic, both what was working correctly and what needed attention.
The transparency made the difference:
“Trey Bradford with Caswell Heating and Air came out today and a Tuneup for us, hadn’t done one in a few years. He showed me picture of all the stuff good and bad going on with the AC in the attic. He was a pleasure to deal with, great Christian kid. He is a PLUS to have as an employee for Caswell.”
This is one of the most common scenarios our technicians encounter in Opelika: a homeowner who has been putting off maintenance for two or three seasons, a system that appears to be functioning but has a capacitor reading near the bottom of its acceptable range, refrigerant pressures that have drifted a few PSI low from a slow leak, and coil surfaces that have accumulated enough debris to reduce efficiency measurably. None of these conditions trigger an obvious symptom until one of them crosses a threshold, and the system stops cooling.
Why Opelika’s Climate Makes Annual Maintenance Essential
Opelika shares Lee County’s climate with Auburn, sustained summer heat above 90 degrees Fahrenheit from June through August, with humidity levels that keep most systems running 10 or more hours per day during peak season. An AC system in Opelika running through a full Alabama summer cycles the compressor thousands of times between May and September. Each cycle stresses the run capacitor slightly. The contactor arcs a small amount on every startup. The refrigerant circuit experiences pressure cycling across every cooling cycle. Over a full season, this accumulated wear shows up in measurements that a technician with the right equipment can identify and address before the component fails.
Opelika also has a significant proportion of homes built in the 1970s through 1990s, where original ductwork and equipment installation have not been evaluated since the system was installed. A maintenance visit that uncovers a duct section that has disconnected in the attic, or an evaporator coil that has been accumulating debris because of a filter that was not being changed on schedule, explains symptoms that homeowners had written off as the system “just getting old.”
Meredith Peel called Caswell Heating Air after concerns about air quality in her home and described a team that inspected what was happening under the house and communicated every finding honestly before recommending any work:
“Breathing clean air thanks to the folks at Caswell. Keith pinpointed our issues under the house and though we needed a major overhaul of our ductwork, we are confident in the integrity of the inspection, fairness of the quote, and quality.”
What Our AC Maintenance Process Includes
Step 1: Filter and Airflow Assessment. The air filter is inspected and its restriction level documented. A heavily loaded filter reduces airflow across the evaporator coil, raises suction pressure, and can cause the coil to ice. We replace the filter or document the correct replacement interval based on the filter type and household conditions.
Step 2: Refrigerant Pressure Measurement. Manifold gauges are connected to the service valves and both high-side and low-side pressures are measured under operating conditions. Readings are compared against manufacturer specifications for the current outdoor ambient temperature. A low-side reading more than 10 PSI below specification typically indicates a refrigerant deficit or a metering device issue. We document the readings and explain the finding before recommending a follow-up repair.
Step 3: Electrical Component Testing. Run capacitors for the compressor and condenser fan motor are tested with a capacitance meter. A reading more than 10 percent below the rated microfarad value flags the capacitor for replacement — this is the component most commonly responsible for no-start failures in Alabama’s heat. Contactor contact surfaces are inspected for arc damage and pitting.
Step 4: Coil Inspection and Cleaning. The outdoor condenser coil is inspected for debris, fin damage, and restricted airflow. Coil cleaning is performed where needed. The indoor evaporator coil is inspected for ice formation or visible buildup at the coil face. A clean coil transfers heat efficiently; a dirty one raises operating pressures and compressor load.
Step 5: Condensate Drain Inspection. The condensate drain pan and drain line are checked for standing water and algae buildup. A blocked drain causes water overflow at the air handler, leading to ceiling or floor damage. Drain clearing is completed where needed.
Step 6: Temperature Differential Measurement. The technician measures return air and supply air temperatures with a digital thermometer. A properly functioning residential system delivers a 16 to 22 degree Fahrenheit differential under normal load. A reading below that range with correct refrigerant pressures indicates a coil or airflow issue requiring further evaluation.
Performance Verification After AC Maintenance
Every maintenance visit closes with a final measurement pass after all cleaning and service is complete. We remeasure refrigerant pressures and temperature differential to confirm that service has actually restored the system’s performance rather than just completing a checklist. Amperage draw on the compressor and blower motors is verified against nameplate ratings. You receive a written record of all pre-service and post-service measurements before the technician leaves, documentation that also serves as maintenance records if your equipment warranty requires proof of annual service.

Frequently Asked Questions About AC Maintenance in Opelika, AL
How often should Opelika homeowners schedule AC maintenance?
Once per year is the minimum. Pre-season scheduling before May provides the best appointment availability and ensures problems are addressed before peak summer demand. Comfort Club members receive two visits per year as part of their membership, which covers both a spring cooling tune-up and a fall heating check.
What does Caswell’s $59 tune-up include?
The tune-up includes a full system inspection, coil cleaning, filter check, refrigerant pressure evaluation, electrical component testing, and performance measurement. The technician documents all findings and provides a written repair estimate if any conditions require follow-up. See current specials for any applicable restrictions.
Will the technician show me what was found during the maintenance visit?
Yes. Caswell technicians document their findings and explain the condition of the system to the homeowner before recommending any repair. This includes showing photos of conditions found in the attic or at the equipment where relevant.
Does my AC warranty require annual maintenance documentation?
Most manufacturer warranties require evidence of annual professional maintenance to support claims on major components. Caswell Heating Air provides a written service record at every maintenance visit that serves as the required documentation.
