Energy Efficiency In HVAC

When it comes to heating, ventilation, and air conditioning (HVAC), you will likely hear quite a bit about energy efficiency. Air conditioning accounts for just over a quarter of energy use in Arizona homes. As a result, how well your HVAC unit functions can have a large impact on your energy bills. A more efficient system can be incredibly beneficial. 

Here are some tips for improving the energy efficiency of your HVAC: 

Installing a New HVAC Unit

When you install a new system, there are a few different factors that can indicate how efficient it is. 

These include:


A system’s seasonal energy efficiency ratio (SEER) indicates how efficiently the unit operates during the cooling season. It is calculated by dividing the total cooling output in British thermal units (BTU) by the usage in kilowatt hours. A more efficient system will have a higher SEER. To see how a higher SEER might impact your energy costs, you can use Lennox’s energy savings calculator


The United States Environmental Protection Agency (EPA) runs the ENERGY STAR program to promote energy efficiency. Household appliances, including HVAC units, can be ENERGY STAR qualified based on standardized measures of efficiency. 

Energy-Efficient Manufacturer

Some HVAC companies are committed to producing efficient technology and Lennox is one example. Their products are designed with energy conservation in mind and many of them are ENERGY STAR qualified. Signature Heating and Cooling is an authorized Lennox dealer and can install a state-of-the-art Lennox HVAC system to help lower your monthly energy costs. 

Improving the Energy Efficiency of Your Current Unit

If you want to improve the efficiency of your current HVAC system, there are many steps you can take. 

These include: 

Change Your Air Filters

If your air filters are dirty, then your unit has to work harder to keep your home at the ideal temperature. Changing and cleaning your filters regularly keeps your system running smoothly. How often you should do so varies depending on the system, but every 3-4 months is a good general guideline. 

Perform Regular Maintenance

Your HVAC may be using more energy than necessary without you even realizing it. When you hire our professionals to perform a yearly maintenance check, we can catch potential issues before they become larger concerns.

Complete Repairs as Needed

While it may be tempting to put off repairs, this can actually cost you more money in the long run. Any issues with your system may make it work harder to heat or cool your home. As a result, you may receive higher utility bills. Our team can repair your system and we are always completely transparent about issues we find and any associated repair costs.
