Upgrading to a New HVAC System Might Be Easier Than You Think. Heat pumps have become a popular choice for homeowners looking to efficiently heat and cool their homes year-round. Their ability to transfer heat rather than generate it makes them an energy-smart option that can lower utility bills while maintaining comfort.
However, many homeowners unintentionally waste money due to common thermostat mistakes and misconceptions about how to best use their heat pump systems. Understanding and correcting these errors empowers you to maximize savings, improve comfort, and get the most out of your investment.
Mistake #1: Constantly Adjusting the Thermostat
A common misconception is that frequently changing your thermostat settings will help save energy. In reality, rapidly switching temperatures or making drastic changes forces your heat pump to work harder to reach the new setting, which can waste energy and increase wear and tear.
Heat Pump Hack: Set your thermostat to a consistent, comfortable temperature and resist the urge to make constant adjustments. Using programmable or smart thermostats that automatically adjust settings based on your schedule can help maintain steady comfort while optimizing energy use.
Mistake #2: Using Emergency Heat Mode Unnecessarily
Many heat pumps come equipped with an “emergency heat” or “auxiliary heat” setting intended for extremely cold conditions when the heat pump alone can’t maintain temperature efficiently. Some homeowners mistakenly leave their system in this mode, unaware that it uses electric resistance heating, which is far more expensive to run.
Heat Pump Hack: Use emergency heat only when necessary—typically during very cold spells—and switch back to regular heat pump mode as soon as possible. If you’re unsure when to use emergency heat, consult your system’s manual or contact a professional for guidance.
Mistake #3: Setting the Thermostat Too High or Too Low
Extreme thermostat settings don’t make your home heat or cool faster, but they do make your heat pump run longer and consume more energy. For example, setting the thermostat to 78°F on a cold day won’t warm your home faster than setting it to 68°F; it just wastes electricity.
Heat Pump Hack: Choose a reasonable, consistent temperature—usually around 68°F in winter and 78°F in summer—for optimal comfort and efficiency. Small temperature adjustments can be better managed with zone controls or smart thermostat features.
Mistake #4: Neglecting Thermostat Placement
Thermostats placed in direct sunlight, near drafts, or close to heat sources can give inaccurate readings, causing the heat pump to turn on or off at the wrong times. This leads to inefficiencies and discomfort.
Heat Pump Hack: Ensure your thermostat is installed in a central location away from windows, vents, and appliances. If you suspect poor placement, ask your HVAC technician to evaluate and recommend an ideal spot.
Mistake #5: Ignoring Regular Maintenance and Filter Changes
Even the best thermostat settings can’t compensate for a poorly maintained heat pump. Dirty filters, clogged coils, or low refrigerant levels make your system work harder and reduce efficiency.
Heat Pump Hack: Schedule annual professional maintenance and change or clean air filters every 1-3 months during heavy use seasons. A well-maintained heat pump performs better, lasts longer, and uses less energy.
