More than half of your utility expenses consist of your HVAC system bills. This makes the central heating and cooling system the largest energy expense. However, you can do a lot to improve the efficiency of your HVAC system while controlling your energy expenses. An HVAC system is the most energy-intensive system in your home that requires proper maintenance if you want to improve its energy efficiency. The increased energy bill is clear sign that your HVAC system has lost its energy efficiency. 

Listed below are some practical tips that can significantly improve the energy efficiency of your HVAC system.

1. Stay on Top of Maintenance:

Nothing runs in its optimal condition forever. Schedule an annual maintenance service to keep your HVAC system working at its best. Yearly maintenance checks can save you money in the long run as you will not have to spend on the costly repairs later. An HVAC technician can spot small problems such as damage, leaks and energy consumption issues before they get worse. 

2. Change the Air Filters:

Most filters of the HVAC system will do the best if they are cleaned at least once every month, or as recommended by the manufacturer. If you live in a dusty region, you may have to change them or clean them more often. Blocked air filters are the common cause of energy efficiency issue. Clogged filters cause your system to run longer for cooling or heating your space, and thereby uses more power. Therefore, don't be lazy to change the air filters of your HVAC unit. 

3. Power Down Electronics:

Switch off your electronics and appliances such as computers, media systems, exercise equipment, and other machinery when not in use. This will help to increase the energy efficiency of your cooling units as these electronics and equipment release heat and draw electricity. As less heat is generated inside your home, your AC will use less power to cool your space and will save you the energy. 

4. Preserve Airflow of Your Unit:

Keep your HVAC units clear of debris, dust, and leaves. Also, make sure that the ducts and vents are not blocked by furniture. Preserving airflow is also essential to improve the energy efficiency of your HVAC unit. If you want to replace your old unit for an upgraded, energy-efficient HVAC system, buy it directly from a wholesaler. 

5. Insulate to Save that Valuable Conditioned Air:

If your house is poorly insulated, you cannot achieve energy efficiency no matter how much you care for your HVAC system. Get better efficiency of your unit by trapping in all the air it produces. Install properly insulated windows. Ducts, pipes, and outlets can be the leaks for your conditioned air. Inspect them and add proper insulation.  

6. Clean Ducts and Vents:

Cleaning air ducts of your unit is similar to replacing air filters. The purpose is to provide a clear pathway for airflow from your HVAC unit. Duct cleaning also improves quality of your home air besides improving energy efficiency. Likewise, vents should also be clear. Most vent designs can be easily removed for cleaning.
