Heating & Cooling F.A.Q.

Frequently Asked Questions

You should change your HVAC air filter every 1-3 months, depending on factors like filter type, household pets, allergies, and overall air quality. A clogged filter reduces airflow, making your system work harder and increasing energy costs. If you have pets or someone in your home has allergies, you may need to replace the filter more frequently to keep the air clean. 

Higher-efficiency filters, like HEPA filters, may last longer but should still be checked regularly. Keeping a fresh filter in place helps maintain system efficiency, improves indoor air quality, and extends the life of your HVAC unit.

Unusual noises from your HVAC system can indicate mechanical issues that need attention. A banging or clanking sound may mean a loose or broken component inside the system. A high-pitched squealing noise often signals a belt or motor issue, while a hissing sound could indicate a refrigerant leak. If you hear rattling, it may be due to loose parts or debris in the system. 

It’s important to have these noises checked by an HVAC professional as soon as possible to prevent further damage and costly repairs.

A programmable thermostat allows you to set temperature schedules that automatically adjust based on your daily routine. By lowering the temperature when you’re asleep or away from home and raising it when needed, you can significantly reduce energy consumption. Some smart thermostats even learn your preferences and make automatic adjustments for maximum efficiency. 

These thermostats can be controlled remotely through a smartphone app, providing added convenience. Over time, using a programmable thermostat can lead to noticeable savings on your heating and cooling bills.

Refrigerant leaks in an HVAC system can be caused by corrosion, wear and tear, or improper installation. Over time, the copper coils in your system can corrode, leading to tiny holes where refrigerant escapes. Vibration and frequent system cycling can also weaken connections and cause leaks. If your system was not installed correctly, loose fittings or improper sealing can result in refrigerant loss. 

A refrigerant leak can lead to poor cooling performance, higher energy bills, and potential system failure. If you suspect a leak, it’s important to have an HVAC professional inspect and repair the issue as soon as possible.
