The HVAC system is one of the most expensive items on your energy bill. Air conditioning can account for at least 50% of your total energy costs during summer. Replacing your HVAC system with the latest, more efficient model can significantly save energy.

However, other simple, more cost-effective HVAC energy-saving tips can help improve your home’s energy efficiency and significantly reduce your electric bill this summer.

HVAC Energy Saving Tips


Uphold Routine HVAC Maintenance

If your system is not working efficiently in the first place, you may not benefit from the other AC energy-saving tips we present here. Follow a regular maintenance checklist to ensure you cover all essential aspects of your HVAC system.

If you have not yet invested in a reliable maintenance program for your air conditioning system, consider scheduling a semi-annual service with a reputable local HVAC company. A qualified HVAC professional will ensure your system remains in good shape and operates as efficiently as possible, saving you money on electric bills.

Set Your Unit to Optimum Temperature Range

Most HVAC units have optimum temperature ranges to maximize energy efficiency. Check your owner’s manual to find out the most efficient temperature range for your unit. According to the U.S. Department of Energy, the most energy-efficient HVAC temperature setting for summer is 78 degrees Fahrenheit.

When you are not home, consider reducing or increasing the temperature to minimize your HVAC system’s operation. You should avoid fluctuating temperatures too often. Also, avoid turning the AC system way down on a hot day or up on a cold day, as it can make your system work harder, increasing energy costs.

Invest in a Programmable Thermostat

A programmable thermostat automatically lowers or raises your HVAC temperature on a set schedule. You can set the temperature to increase by 5-10 degrees while away and revert to a comfortable setting an hour before you return.

Some thermostats feature a 7-day programming option so that you can customize each day’s settings. Other thermostats have a 5-1-1-day, 5-2-day, or single-week program.

You should consider installing a smart thermostat, a more advanced version of a programmable thermostat. With a smart thermostat, you can control your home’s temperature from your smartphone. Some of these devices can even study your lifestyle habits and adjust accordingly to keep your home as efficient as possible.

Replace Your Air Filter

Air filter replacement serves as another effective summer energy-saving tip to keep your AC system running smoothly and efficiently. Dirty, clogged filters impede efficient airflow and lower your AC unit’s ability to absorb heat.

Replacing your dirty filter with a new one can lower your air conditioner’s energy usage by up to 15%. Experts advise that you replace or clean your HVAC system’s filter every one or two months. The more you use your AC system, the more frequently you should clean or replace the filters.

Get a Higher SEER Unit

Consider investing in a higher SEER unit when it’s time to replace your HVAC system. The Seasonal Energy Efficiency Ratio (SEER) shows a heat pump or air conditioning system’s efficiency.

The higher the efficiency ratio, the more cooling you will get for your investment and the lower the energy costs. You might want to consult a certified HVAC contractor to determine the appropriate efficiency level for your home.

Check and Seal Air Leaks

Insulating and sealing your home’s exterior can save you up to 20% on heating and cooling costs. The exterior includes the outer walls, doors, windows, floors, and ceilings.

Sealing air leaks with spray foam, caulk, or weather stripping and insulating the attic will ensure heat stays inside your home in the winter and keeps it out in the summer. Implementing these electricity bill reducing tips can keep you cool and save you money.
