Rising energy costs prompt many homeowners to examine the efficiency of their heating and cooling systems. Although your HVAC system works year-round to keep your home comfortable, small maintenance issues or simple mistakes can cause it to overwork, resulting in higher energy bills.
Here are some common mistakes people make with their HVAC systems, along with easy fixes that can save money, reduce strain on the equipment and help keep your home comfortable from one season to the next.
CHOOSING THE WRONG-SIZED SYSTEM
Installing an HVAC system that’s too large or too small is an expensive yet avoidable mistake.
An oversized system may cool quickly, but will not remove humidity, leaving rooms damp and uncomfortable. A system that’s too small struggles to maintain the temperature, runs nonstop and wears out parts early.
When selecting a system, consult an expert to assess your home’s heating and cooling needs. Certified professionals can help ensure proper sizing, improving comfort and efficiency.
LETTING OUTSIDE AIR SNEAK IN
Over time, caulking can dry out and crack, making the system’s job even harder to do effectively. Cracked seals around windows or doors may seem insignificant, but they allow hot, humid air to enter during summer and cold drafts to enter during winter, forcing your HVAC system to work harder.
Keep windows and doors tightly closed when running your HVAC and check for broken or aging seals. Resealing can quickly improve comfort and energy use.
OVERLOOKING SEASONAL MAINTENANCE
Neglecting to perform seasonal maintenance can silently increase energy costs. Dirty filters, worn belts or failing parts force systems to use more power. Like a car, your HVAC needs regular checkups.
Schedule maintenance at least twice a year, ideally before cooling and heating seasons. Certified technicians can inspect filters, capacitors, motors and other components to ensure everything runs efficiently.
BLOCKING VENTS AND REGISTERS
If air can’t move, it can’t heat or cool your home effectively. Furniture, rugs or curtains that cover supply or return vents restrict airflow, causing your system to work harder than necessary.
Keep vents and registers open and clear of obstructions to make sure your HVAC system has balanced airflow to maintain consistent temperatures throughout your home.
ATTEMPTING DIY THERMOSTAT INSTALLATION
Smart thermostats help control comfort and save energy, but improper installation can lead to issues. Wiring mistakes can lead to inconsistent performance or damage.
Leave thermostat installation to the professionals. A licensed contractor will wire it correctly and pair it with your system.
THE BOTTOM LINE
Avoiding common HVAC missteps saves energy, reduces your bills and keeps your system running smoothly. Selecting the right-sized equipment, sealing air leaks and scheduling professional maintenance are crucial steps. Small efforts make a big difference.
Don’t fall victim to power outage scams. When widespread outages occur, scammers may target affected utility customers. They can contact you via call, text or email, urging you to act quickly and provide personal information to restore service. Always communicate with your electric co-op through official channels, such as their website, mobile app or phone number listed on your bill. Your safety and personal information are worth taking a moment to pause and verify unknown senders.
