AC System Maintenance in Corpus Christi
At minimum, once per year, ideally in spring before the brutal summer heat arrives. However, because Corpus Christi systems run eight to ten months per year and work significantly harder than ACs in cooler or drier climates, twice-yearly maintenance is even better. A spring tune-up prepares your system for summer. A fall checkup catches any wear from the long cooling season and prepares your heating system for winter. Think of it like oil changes for your car. The manufacturer might say every 5,000 miles, but if you’re driving in extreme conditions, more frequent changes extend the engine’s life. Your AC is operating in extreme conditions every single summer.
A thorough tune-up covers about 16 checkpoints. We inspect and clean the evaporator coil, which collects dust and restricts airflow if neglected. We clean the condenser coil on your outdoor unit, which gets clogged with dirt, leaves, cottonwood fluff, and salt residue in coastal areas. We check refrigerant levels and look for signs of leaks. We inspect electrical connections, capacitors, contactors, and wiring for wear or corrosion. We test the thermostat for accuracy and calibration. We clear the condensate drain line, which is especially important in humid climates where algae growth causes clogs and water leaks. We check the blower motor and fan blade, lubricate moving parts if needed, and replace the air filter. When we’re done, we’ll tell you exactly what we found, what condition your system is in, and whether any repairs should be on your radar.
Coastal environments accelerate wear on HVAC equipment in multiple ways. Salt air corrodes metal components on your outdoor unit, including the condenser coil fins, copper tubing, electrical terminals, and the cabinet itself. Homes within a few miles of the Gulf experience noticeably faster deterioration than homes 20 miles inland. High humidity forces your system to work harder removing moisture from the air, which strains the compressor and can lead to frozen evaporator coils if airflow is restricted. Sandy soil and airborne particulates clog condenser coils faster than in other climates. And because your system runs nearly year-round, components accumulate wear much faster than systems up north that only run three or four months. Regular maintenance catches these coastal-specific issues before they become expensive failures.
A tune-up is a one-time service. You call, we come out, we inspect and clean your system, and you pay for that visit. A maintenance plan is an annual membership that includes scheduled tune-ups, typically two per year, plus additional benefits. Plan members get priority scheduling, which means you move to the front of the line during peak summer when everyone’s AC is breaking down. You get discounts on any repairs that come up during the year. Some plans include the diagnostic fee waiver, so if something breaks, we come diagnose it for free. The plan makes sense for homeowners who want ongoing protection, predictable costs, and the peace of mind that comes from knowing their system is being watched year-round.
If your AC is running but something seems off, pay attention to specific symptoms. Is the air coming from your vents warm or not as cold as it used to be? Is the system running constantly without reaching the set temperature? Do you hear unusual sounds like grinding, squealing, rattling, or clicking? Is the system cycling on and off every few minutes? Do you see water pooling around the indoor unit? Is your electric bill suddenly higher than usual for the same usage? These symptoms suggest a problem that needs repair, not just maintenance. On the other hand, if your system is working fine but hasn’t been serviced in a year or more, maintenance will help keep it that way and catch small issues before they become expensive.
Yes, there are a few things you can and should do between professional visits. Change your air filter every one to three months depending on the filter type, whether you have pets, and how much dust your home generates. A clogged filter restricts airflow, makes your system work harder, and can cause the evaporator coil to freeze. Keep the area around your outdoor condenser unit clear of debris, vegetation, and clutter. You want at least two feet of clearance on all sides for proper airflow. Rinse the condenser coils with a garden hose occasionally to remove surface dirt. Check that your vents are open and unobstructed. Beyond these basics, leave the work to a licensed technician. Checking refrigerant pressures, testing electrical components, and cleaning internal coils requires specialized tools, training, and certifications.
A standard tune-up takes 45 minutes to an hour for a typical residential system. If your system has multiple zones, is unusually large, or has accessibility challenges like a hard-to-reach attic unit, it may take a bit longer. If we discover issues during the inspection that require attention, we’ll discuss them with you before doing any additional work. We won’t surprise you with charges or do repairs without your approval. The goal is to complete a thorough inspection within a reasonable time window while keeping you informed every step of the way.
Many HVAC manufacturers require proof of annual professional maintenance to honor equipment warranties. If your compressor fails at year three and you file a warranty claim, the manufacturer may ask for maintenance records. If you can’t provide them, they may deny the claim. Check the warranty documentation that came with your system, or ask us and we can help you understand what’s required. Even if your warranty doesn’t strictly require maintenance, keeping records protects you. And practically speaking, systems that receive regular maintenance rarely need major warranty repairs because problems get caught early.
