4 HVAC Mistakes Homeowners Make During Heatwaves
Don’t Let Summer Mistakes Cost You Comfort
When Colorado Springs experiences a heatwave, air conditioners are pushed to their limits. But sometimes, it’s not just the temperature outside that causes discomfort—it’s avoidable HVAC mistakes happening inside the home. These missteps can reduce system efficiency, raise energy bills, and leave living spaces less comfortable than they should be.
Recognizing and correcting a few common errors can help keep things cool, energy-efficient, and stress-free—even when temps soar past 90 degrees.
Cranking the Thermostat Too Low
It’s tempting to turn the thermostat way down when coming home to a hot house, but this won’t cool the home faster. Instead, it causes the AC to run longer, overworking the system and wasting energy.
Pro Tip: Set the thermostat to a consistent, comfortable temperature—usually between 74°F and 78°F—and give the system time to work.
Ignoring Air Filter Changes
Dirty filters restrict airflow and make the system work harder, especially during high-demand periods. Reduced airflow also means uneven cooling and higher energy consumption.
Pro Tip: Check filters monthly during summer and replace them every 1–3 months, depending on use and indoor air quality needs.
Blocking Vents or Registers
Furniture, curtains, or rugs can unintentionally block airflow from vents. This prevents cool air from circulating properly and can trick the thermostat into running the system longer than necessary.
Pro Tip: Keep at least 12 inches of clearance around vents and registers to ensure unobstructed airflow.
Skipping Regular HVAC Maintenance
A neglected AC unit is more likely to break down during a heatwave. Without seasonal maintenance, dirt builds up on coils, refrigerant levels may go unchecked, and minor issues can turn into costly problems.
Pro Tip: Schedule professional maintenance at least once per year. Technicians will inspect components, clean coils, check refrigerant levels, and optimize system performance.
Frequently Asked Questions About Summer HVAC Use
Should the fan setting be on “auto” or “on” during a heatwave?
Set your thermostat fan to “auto” for better efficiency. This allows the fan to run only when the system is actively cooling, preventing unnecessary energy use.
How can I reduce cooling costs during peak heat?
Use ceiling fans to circulate air, keep blinds closed during the day, and avoid using heat-generating appliances like ovens in the afternoon.
Is it bad to run the AC all day?
Not necessarily. Modern systems are built to handle consistent use, but running nonstop may signal an underlying issue such as poor insulation or low refrigerant.
How often should HVAC systems be serviced in Colorado Springs?
Twice a year is ideal—once before summer and once before winter—to keep your system running efficiently year-round.
