Living in Houston, TX means dealing with intense heat and humidity—especially during the summer months. That’s why your air conditioner isn’t just a luxury; it’s a necessity. But even the most reliable AC units can struggle if they don’t receive regular care. Routine maintenance helps keep your system running smoothly, extends its lifespan, and prevents those costly emergency breakdowns.
As your neighborhood HVAC experts, Ace Comfort Air Conditioning & Heating is here to walk you through seven simple, practical steps every Houston homeowner can follow to keep their AC in top shape.
1. Change Your Air Filters Monthly
Your AC filter is the system’s first line of defense. When it gets clogged with dust, pet dander, and pollen (which Houston is notorious for), your unit has to work twice as hard to pull in air. This puts unnecessary strain on the motor and drives up your electricity bills.
Quick tip:
Set a recurring reminder to replace your filter once a month—especially in peak cooling season. If you’re not sure which filter type fits your system, the team at Ace Comfort Air Conditioning & Heating can help you choose the right one.
2. Keep the Outdoor Condenser Unit Clean
The outdoor unit (aka the condenser) is responsible for releasing the heat your system removes from your home. But in Houston, falling leaves, grass clippings, and even pests can quickly block airflow.
Here’s what you can do:
- Gently rinse the condenser fins with a garden hose (not high-pressure!)
- Clear away any debris within two feet of the unit
- Trim back bushes or plants that are crowding it
Need a deeper clean or worry you may have damaged the fins? Schedule an inspection with a technician for a full tune-up.
3. Check for Refrigerant Leaks
If your AC isn’t cooling like it used to, it could be low on refrigerant. Unfortunately, low levels often signal a leak—which can be harmful to both your system and the environment.
Signs of a refrigerant leak include:
- Ice buildup on the coils
- Hissing sounds from the outdoor unit
- Sudden rise in indoor humidity
This is a repair best left to pros. Our Houston-based HVAC team at Ace Comfort can safely test, recharge, and fix leaks to keep your system efficient and eco-friendly.
4. Clear the Drain Line to Prevent Mold
In Houston’s humid climate, your AC pulls tons of moisture out of the air. That water needs somewhere to go—through a small drain line. Over time, that line can clog with algae or dust, backing up water into your home or AC unit.
DIY drain line flush:
- Turn off your unit
- Find the PVC pipe near the indoor unit
- Pour a 1:1 mix of water and white vinegar into the pipe every 2–3 months
Still experiencing leaks? You might be dealing with a more serious clog that needs professional attention. We offer fast, affordable AC troubleshooting in Houston neighborhoods.
5. Calibrate the Thermostat
A thermostat that’s off by even a few degrees can lead to unnecessary wear and tear on your unit—not to mention a higher energy bill.
Try this:
- Use a separate thermometer to verify your thermostat’s accuracy
- Upgrade to a smart thermostat for more efficient scheduling
- Avoid placing it in direct sunlight or near heat-producing appliances
Not sure what thermostat works best for your home layout? Our installation experts can help you upgrade without the guesswork.
6. Inspect Ductwork for Leaks or Dust
Leaky ducts can waste up to 30% of cooled air—meaning your system is working hard to cool areas that aren’t even getting the airflow. In older Houston homes, duct sealing and cleaning can significantly boost AC performance.
What to look for:
- Uneven temperatures from room to room
- Visible dust buildup around vents
- Whistling or rattling sounds when the AC runs
At Ace Comfort, our techs are trained to identify duct issues that others might miss. Plus, we offer affordable repair services to get your system back on track.
7. Schedule Annual Professional Maintenance
Even if you’re diligent with basic upkeep, annual maintenance by a licensed technician is non-negotiable. A trained HVAC specialist can spot early signs of wear, fine-tune components, and optimize your system for Houston’s climate.
During a professional tune-up, we typically:
- Inspect the motor and electrical connections
- Clean the condenser coils
- Check refrigerant levels
- Lubricate moving parts
- Test the system’s overall performance
This is the best way to avoid unexpected summer breakdowns—and extend the lifespan of your air conditioner.
Why AC Maintenance Matters More in Houston
Houston summers are long, humid, and relentless. Your AC doesn’t get a break, and if it fails in July or August, you’ll likely be stuck waiting in line during peak repair season. That’s why preventive maintenance is a smart, cost-effective investment.
Still unsure if your system needs a check-up? Ask yourself:
- Has your energy bill gone up recently?
- Is your AC making strange noises?
- Does your home take longer to cool down?
If you answered yes to any of these, it’s probably time for a professional AC inspection.
