Want to keep your air conditioner running strong through Rockwall’s scorching summers? Apple AC & Heat Services shares the top AC maintenance tips every Rockwall homeowner should know.
Texas summers can be brutal—and your air conditioner is your home’s frontline defense. But to keep your system running efficiently and avoid surprise breakdowns, regular maintenance is essential. Fortunately, with the right habits and a little help from your local HVAC pros, you can keep your AC unit in great shape all season long.
Here are the most important air conditioning maintenance tips to follow if you want lower energy bills, better cooling performance, and a system that lasts for years.
Change Your Air Filter Regularly
This is the most important—and easiest—maintenance task you can do. Your air filter traps dust, pollen, and debris, protecting both your indoor air quality and your AC’s components. A dirty or clogged filter restricts airflow, making your system work harder and driving up your energy bill.
Change your filter every 1–3 months, depending on usage, pets, and allergies. If your system seems to be struggling, check the filter first.
Keep the Outdoor Unit Clear
Your outdoor condenser unit needs space to breathe. Over time, leaves, grass clippings, dirt, and even trash can accumulate around it, blocking airflow and causing the unit to overheat.
Clear at least 2 feet of space around the unit and gently hose off the fins if they appear dirty. Just be sure to shut off power before doing any outdoor cleaning.
Schedule Seasonal Tune-Ups
Professional AC maintenance is a must—especially before summer hits full force. A trained technician can inspect, clean, and tune your system in ways that go beyond basic DIY tasks. Regular checkups catch problems early and help you avoid costly repairs.
Apple AC & Heat Services offers seasonal tune-ups in Rockwall that include:
- Cleaning evaporator and condenser coils
- Checking refrigerant levels
- Testing electrical components
- Clearing drain lines
- Inspecting motors, fans, and belts
- Thermostat calibration and airflow checks
We recommend servicing your system at least once a year—twice if your unit also handles heating in winter.
Check and Clear the Drain Line
Your air conditioner removes moisture from the air, which drains away through a condensate line. Over time, this line can clog with algae or debris, leading to water leaks or even system shutdowns.
You can flush your drain line with a small amount of vinegar or bleach every few months to help keep it clear. If you see water pooling near your indoor unit or signs of mold, it’s time to give us a call.
Don’t Ignore Unusual Sounds or Smells
AC units should run fairly quietly. If you hear banging, grinding, buzzing, or screeching, it’s a sign something is wrong—often a loose part or failing motor. Similarly, musty or burning smells from vents could mean mold or electrical issues.
Never wait for these signs to go away on their own. Catching issues early is the key to avoiding major repairs.
Keep Your Thermostat Accurate
If your thermostat isn’t working properly, it can make your AC system behave erratically. Whether it’s an older manual model or an outdated digital one, it might be time to consider an upgrade.
We recommend installing a smart thermostat for more precise temperature control, remote access, and better energy efficiency. We can help you choose one that fits your home and install it quickly.
Seal and Insulate Your Ducts
Leaky ducts are a major source of energy loss. Up to 30% of cooled air can be lost through gaps or poorly insulated ductwork, especially in older homes.
During your maintenance check, we can inspect your ducts and seal or insulate where needed. This simple fix can make a big difference in both comfort and cost.
Watch Your Energy Bills
Sometimes the first sign of an AC issue is a spike in your electricity bill. If your system seems to be running constantly or working harder than usual, it may be time for a professional inspection.
Even if your home still feels cool, inefficient operation can shorten your system’s lifespan and eat away at your budget. We’ll make sure everything’s operating at peak performance.
