4 Tips to Enhance HVAC Efficiency

Your HVAC unit consumes a lot of energy to keep your home warm or cool. Fortunately, you can take several steps to maximize the efficiency of your system and save on energy costs. Explore some of these tips below.

1. Replace the Filter Regularly

Dirty filters may be a small part of your HVAC system, but they significantly impact indoor air quality. Indeed, dirty filters are a major cause of HVAC failure as they restrict airflow into the unit’s air handler. This additional strain on the air handler’s motor and fan can cause the system to overheat and fail.

When the filter is dirty, the HVAC unit also works for longer to cool and heat your home, and you, therefore, pay more in utility bills. Dust and other contaminants can also degrade other HVAC parts, such as valves and fan motors, resulting in high repair costs.


Fortunately, filters are inexpensive and easy to change. Replace the filter more frequently if you have several pets or live in a dusty environment. If you have not replaced the filter before, an HVAC technician can show you where to access it.

2. Upgrade to a Programmable Thermostat

A programmable thermostat reduces the demand for cooling and heating, and it prolongs an HVAC unit’s service life. If you still use a manual thermostat, you miss out on the many benefits of a programmable model.

One benefit is that you can log into a programmable thermostat’s controls from anywhere via Wi-Fi connectivity and adjust the temperature. If no resident is at home during the day, use an energy-efficient setting.

A programmable thermostat also lets you customize temperatures for different times in the day or week. You can set weekday routines for when your house is empty and weekend schedules for when everyone is home. A simple temperature change during the week can save you a lot in energy costs. By adjusting temperatures as needed, you minimize the strain on your HVAC system.

3. Check for Leaks in the Ductwork

Conditioned air leaks through any holes in your HVAC unit’s ductwork, resulting in hot or cold spots. If you have noticed long temperature adjustment times or high utility bills, check the ducts for leaks. Typically, leaks appear as separated sections in the ducts that run through basements, attics, garages, and crawl spaces.

Also, look out for poorly hung ducts, dried-out or loose duct tape, or crumpled ducts with kinks. While some homeowners attempt to seal duct leaks, a professional can do a much better job and will test the airflow when finished. Insulate the properly sealed ducts to minimize energy loss.

4. Schedule Maintenance

Ultimately, preventative maintenance is the superior way to enhance HVAC efficiency. Your unit has multiple components, and many things can go wrong and affect its performance.

To remedy poor airflow, an HVAC expert checks for issues in the ductwork and blockages in the condenser unit. HVAC contractors may also oil the motors, ensure proper tension in the motor belts, and confirm refrigerant levels. Additionally, the technicians will confirm the thermostat’s accuracy and make adjustments. This regular maintenance keeps the HVAC system operating smoothly and efficiently throughout the year.

An HVAC technician can also perform an energy audit to determine how much energy your home uses. The expert can advise you to retrofit your existing system or upgrade to a new one if needed. Two checkups in the fall and spring are enough to ensure your unit is ready for cold and hot seasons.

A poorly maintained HVAC system is a ticking time bomb, as it can break down during summer or winter when you need it the most. Preventative maintenance is the best way to enhance your unit’s efficiency. However, if repairs are necessary, you can call our technicians at Carrano Air HVAC Contractors.
