5 HVAC Efficiency Tips to Lower Your Energy Bills This Summer

1. Change or Clean Your Air Filters Regularly

Your HVAC filter is the first line of defense against dust, pollen, and debris. When it’s clogged, your system works harder, using more energy and wearing down faster. 😤

• Pro Tip:
  • Change your air filter every 1–3 months, depending on pets, allergies, or local air quality. Bonus: Clean filters = a clean indoor environment!

2. Seal Leaks in Ductwork and Around Your Home

Air leaks = energy leaks. If cooled air escapes through duct gaps or drafty windows, your system must run longer to maintain the set temperature.

🛠️ Fixes to consider:

• Have your ductwork inspected for leaks or damage
• Seal gaps around doors/windows with weather stripping
• Add insulation to attics and crawl spaces

🔧 At Thomas Hoffmann, we provide professional duct sealing to maximize airflow and efficiency.

3. Upgrade to a Smart Thermostat

Still using a manual thermostat? You could be overspending. Smart thermostats, such as Ecobee or Nest, learn your preferences, adjust settings automatically, and allow you to control your home’s temperature from your phone. 📱

🌡️ Features to look for:

• Adaptive schedules
• Remote access
• Energy usage reports

4. Schedule a Pre-Summer HVAC Tune-Up

Think of this as an “oil change” for your AC. A seasonal tune-up keeps your system running smoothly, identifies issues early, and ensures peak efficiency during the hottest days of the year.

🧰 What we check during a tune-up:

• Refrigerant levels
• Electrical connections
• Coil cleanliness
• System calibration

5. Don’t Block Vents or Thermostats

Seems obvious, but it’s a common mistake! If furniture or rugs block air vents, your system can’t circulate air properly, leading to uneven cooling and longer run times. 🚫🛋️

Also, avoid placing electronics near your thermostat — they can cause inaccurate readings and trigger unnecessary cooling.

• ➡️ Do this today:
  • Walk around your home and check for blocked vents or heat sources near your thermostat.

🌬️ Bonus Tip: Consider an HVAC System Upgrade

If your system is more than 10–15 years old, even the best efficiency tips might not be enough. Modern systems are significantly more efficient, and qualifying St. Louis homeowners may be eligible for rebates or tax credits for energy-efficient upgrades.
