Impact of July Weather on Your Cooling Needs
July’s heat and humidity put significant demands on your AC system. Discover the challenges and solutions for keeping your home cool and comfortable.
Challenges from Extreme Heat
Houston’s July heat, often exceeding 95°F, can overwork traditional AC systems, leading to breakdowns or higher energy bills. Older units may struggle to maintain indoor temperatures below 75°F, especially in poorly insulated homes.
Managing Hot Nights
Nighttime lows above 75°F mean your AC runs nearly nonstop. This increases energy costs and wear on your system. To improve comfort, use ceiling fans to circulate cool air and set your thermostat to 78°F at night for efficiency.
Addressing High Humidity
High humidity (75–85%) can make indoor air feel sticky, even with the AC on. Dehumidifiers or AC units with strong dehumidification settings are essential to maintain indoor comfort and prevent mold growth in humid areas like bathrooms for basements.
AC Services That Help You Stay Cool in Houston
Professional AC services can keep your home comfortable during Houston’s brutal July heat. Explore the best options for maintenance, upgrades, and energy savings.
AC Tune-Up and Maintenance
Schedule an AC tune-up in May or June to prepare for July’s heat. A professional inspection from 75 Degree AC can identify issues like low refrigerant or dirty coils, ensuring your system runs efficiently. Regular maintenance can extend your AC’s lifespan and reduce energy costs by up to 15%.
Ductless AC
Ductless AC systems, like mini-splits, are ideal for Houston homes without ductwork or for room-specific cooling. They’re energy-efficient, quiet, and easier to install than traditional systems. For example, a ductless unit can cool a 500-square-foot room while using 20–30% less energy than a central AC.
Smart Thermostats
Smart thermostats like Nest or Ecobee can save Houston homeowners 10–12% on cooling costs. These devices learn your schedule, adjust temperatures automatically, and allow remote control via smartphone apps. For example, setting your AC to 80°F when you’re away and 78°F when you’re home can significantly lower your CenterPoint Energy bill.
Helpful AC Maintenance Tips for Extreme Heat
Beat the July heat with practical AC maintenance strategies. Check out these tips to keep your system running smoothly and your bills low.
Checklist for Preparing Your AC for Summer Heat
- Check Filters: Replace or clean AC filters every 1–2 months to maintain airflow and efficiency.
- Clear Debris: Remove leaves, dirt, or grass from around your outdoor AC unit.
- Inspect Insulation: Seal windows and doors to prevent cool air leaks, especially in older Houston homes.
- Test Thermostat: Ensure your thermostat is calibrated to avoid overcooling.
- Schedule Maintenance: Book a professional tune-up with 75 Degree AC to catch issues early.
Tips to Reduce Monthly Energy Bills at Home
- Use Ceiling Fans: Run fans counterclockwise to push cool air down, allowing you to raise your thermostat by 2–3°F.
- Close Blinds: Block sunlight with blackout curtains during the day to reduce indoor heat gain.
- Upgrade Insulation: Add attic insulation to keep your home cooler, especially in neighborhoods like Montrose with older homes.
- Check for Rebates: Explore CenterPoint Energy’s energy efficiency programs for rebates on AC upgrades or smart thermostats.
