How to Measure the Efficiency of Your HVAC System

An efficient HVAC system is crucial to ensuring the comfort of your home while maintaining energy efficiency. In fact, a report by the Department of Energy has found that HVAC energy efficiency can reduce your overall energy usage by as much as 35%. But maintaining proper energy efficiency can be difficult, as compromising issues can crop up from several different places.

Here are some steps to determine the efficiency of your current HVAC system, identify detrimental factors, and improve overall performance.

HVAC System Efficiency Assessment

Your first step in assessing HVAC energy efficiency is to check the temperatures in every room of your house. You’re looking for even temperature readings across the entire home; if there are any areas where the temperature is significantly warmer or cooler, that would indicate that air is not flowing properly throughout the entire system.

Next, you should check the age of your HVAC unit. HVAC units should be replaced roughly every ten years, and if the unit was already installed when you purchased the home then there’s a chance that it could be very outdated.

Finally, you should check the vents themselves to determine the temperature of air flowing in and out of your system. You can do this accurately by holding a basic thermometer up to each vent for about five minutes. The air exiting your vents should optimally be 14 to 20 degrees cooler than the air going in. If you’re seeing a consistent variance from this temperature, it would indicate that your HVAC system is not operating efficiently.

Improving HVAC System Efficiency Performance

In improving your system’s performance, you want to start simple and monitor your HVAC system as you increase your efforts. The first step is to thoroughly clean your outside unit. Sometimes something as simple as poor sanitation can have a considerable impact on the energy efficiency of your home.

You should make sure that you’re changing out your air filters every three months. If you’re on a regular changing schedule and still seeing energy issues, it might indicate that conditions in your home like pets or excessive dust are causing the filters to wear out early. If this is the case, you should try increasing the changeout rate.

HVAC System Efficiency Troubleshooting

If you’re still seeing issues, your next step is to check your air ducts or schedule a professional inspection. Cracks, holes, and damage in your ducts can greatly compromise the functionality of your HVAC, along with warping from high temperatures. You can repair small holes and cracks with duct tape, but larger issues will require professional assistance. You’ll also want to have your ducts thoroughly cleaned, as dust and debris buildup can hamper performance in addition to causing health and sanitation issues.

If you’re still seeing performance and energy issues after this, it could indicate that your HVAC system is outdated or was not installed properly. At this point, you should reach out to a seasoned professional to evaluate the system, identify the root issue, and determine the most effective solution to improve the energy efficiency of your HVAC system.
