Your HVAC system makes up almost half of your home’s energy costs, and an inefficient system uses more electricity and costs you more money. You can lower your energy use and save money by understanding your HVAC system and adopting simple habits, using smart technology, and getting professional maintenance.
Understanding Your HVAC System
To save money, you first need to understand what you are paying for. Your HVAC system is responsible for moving air throughout your home to maintain a comfortable temperature and good air quality. It typically consists of a furnace for heating, an air conditioner or heat pump for cooling, and a network of ducts that distribute the conditioned air.
The energy consumption comes from two main places: the motors that blow the air and the energy required to actually heat or cool that air. If your system has to work harder than necessary—because of blocked airflow, extreme temperature settings, or old machinery—it draws more power. An efficient system achieves the desired temperature quickly and maintains it with minimal effort, whereas an inefficient one runs constantly, cycling on and off rapidly, which causes wear and tear while spiking your electric meter.
Simple DIY Tips for Instant Savings
You don’t always need a technician to improve your home’s efficiency. There are several maintenance tasks and habit changes you can tackle yourself that yield immediate results.
Change Your Air Filters Regularly
This is the golden rule of HVAC maintenance. A dirty, clogged air filter restricts airflow, forcing the system to struggle to pull air through the intake. This adds strain to the blower motor and reduces the system’s ability to heat or cool effectively. Check your filter every month and replace it at least every three months—or more often if you have pets.
Seal Drafts and Leaks
Your HVAC system works hard to condition the air inside your house. Don’t let that expensive air escape through cracks in the building envelope. Inspect your windows and doors for drafts. Adding weatherstripping or applying caulk around window frames is an inexpensive fix that stops conditioned air from leaking out and prevents outdoor air from sneaking in.
Use Your Curtains Strategically
The sun is a powerful heat source. In the summer, keep blinds and curtains closed during the hottest parts of the day, especially on south and west-facing windows. This prevents solar heat gain, reducing the load on your air conditioner. In the winter, do the opposite: open the curtains during the day to let the sun naturally heat your home, and close them at night to add an extra layer of insulation against the cold glass.
Keep Vents Open and Clear
A common myth is that closing vents in unused rooms saves money. In reality, modern central air systems are designed to distribute air evenly based on a balanced pressure load. Closing vents disrupts this balance, increasing pressure in the ductwork and potentially causing leaks or damaging the blower. Keep vents open and ensure they aren’t blocked by furniture or rugs to maintain proper airflow.

The Power of Smart Thermostats
Manual thermostats are prone to human error. We forget to turn them down when we leave for work, or we crank them up too high when we get cold, leading to energy waste. Smart thermostats solve this problem by automating temperature control.
These devices allow you to program schedules that align with your daily routine. You can set the system to use less energy while you are away and have it return to a comfortable temperature right before you get home. Many models also feature geofencing which uses your smartphone’s location to detect when you leave the house and automatically adjusts the temperature to an eco-friendly setting.
Furthermore, smart thermostats provide data on your energy usage. They can show you exactly how many hours your system ran and suggest tweaks to your schedule to save even more. The ability to control your home’s climate remotely via an app ensures you never accidentally cool an empty house again.
The Importance of Professional Maintenance
While DIY efforts are vital, they cannot replace the expertise of a professional technician. An annual or bi-annual tune-up is like a physical exam for your HVAC system. It catches small issues before they turn into expensive breakdowns and ensures everything is running at factory specifications.
During a professional maintenance visit, a technician will clean the coils, check refrigerant levels, inspect electrical connections, and lubricate moving parts. Clean coils transfer heat more efficiently, and proper refrigerant levels are crucial for cooling performance.
Regular maintenance also extends the lifespan of your unit. A neglected system may only last 10 years, while a well-maintained one could last 15 to 20. If you do encounter specific issues, such as strange noises or uneven cooling, do not hesitate to call for help. Whether you need a simple tune-up or specific air conditioning repair services in Draper, relying on qualified experts ensures the job is done correctly and safely.
Considering Long-Term Upgrades
Sometimes, efficiency issues go beyond maintenance. If your HVAC system is more than 10 or 15 years old, it may be time to consider a replacement. Older units are significantly less efficient than modern counterparts due to advancements in technology and stricter environmental standards.
When shopping for a new unit, look at the SEER2 (Seasonal Energy Efficiency Ratio) rating for air conditioners and the AFUE (Annual Fuel Utilization Efficiency) for furnaces. The higher the number, the more efficient the unit. While high-efficiency models come with a higher upfront price tag, the monthly savings on your utility bill can offset the cost over time.
Additionally, consider improving your home’s insulation. Even the best HVAC system cannot compensate for a poorly insulated attic or walls. Adding insulation helps your home retain temperature longer, meaning your HVAC system doesn’t have to run as often.
Conclusion
Reducing your HVAC energy costs is a journey that starts with small steps. By staying on top of filter changes, utilizing smart technology to manage your temperature, and investing in regular professional care, you can create a home that is both comfortable and cost-effective.
