5 Hidden HVAC Problems That Can Increase Energy Bills

Leaky Ductwork

Ductwork acts as the delivery network for conditioned air. If there’s a leak, damaged section, or disconnected joint, cooled and heated air can escape into crawlspaces, attics, basements, or cavities in the wall. Research shows that duct leaks can waste up to 40% of conditioned air, depending on the severity of the problem. Unfortunately, leaks and breaks can go undetected for a long time, overwhelming your unit and making it work harder. Common signs your ductwork needs attention include weak airflow, excessive dust, and certain rooms that feel too cold or too hot.

Thermostat Calibration Problems

The thermostat is the control center for your HVAC system. If it loses calibration or reads temperatures inaccurately, it can cause your heating and cooling equipment to run longer than necessary and cycle improperly. The last thing you want is a home that is two degrees warmer than it actually is, resulting in a continuously running unit even after achieving the desired atmosphere. Many people never suspect a problem until it is too late, and a simple calibration is no longer a viable option.

Dirty Coils

While it is general knowledge to regularly replace air filters, few people realize that their HVAC systems contain coils that require attention. The evaporator coil inside your indoor unit absorbs heat, and the condenser coil in your outdoor unit releases that heat. These coils accumulate dirt, dust, pollen, and other debris that interfere with this process and make heat transfer less efficient. Dirty coils don’t necessarily stop your HVAC system from cooling indoor spaces, but it forces it to work harder to do it. If your system takes longer cooling cycles, reduces cooling performance, or forms ice on indoor components, hire a professional HVAC company for maintenance.

Minor Airflow Restrictions

Sometimes, the problem is not the system, but a simple issue. Whether it is closed registers, furniture placed over vents, blocked return-air grilles, or outdoor debris around the condenser unit, addressing these issues can restore smooth airflow. These inefficiencies may seem insignificant individually, but they can reduce system efficiency and increase operating costs. Restricted airflow is one of the most common contributors to HVAC performance issues and elevated energy usage. Luckily, taking a proactive approach toward HVAC service can improve airflow and keep your system running optimally year-round.
