HVAC FAQ: Common Questions and Answers

How often should I change my air filter?

It is recommended to change your air filter every 1-3 months, depending on the type of filter and the air quality in your home. A dirty air filter can restrict airflow and cause your HVAC system to work harder, leading to reduced efficiency and potentially damaging the system.

Why is my HVAC system making strange noises?

Strange noises can be caused by a variety of issues, such as loose parts, a malfunctioning fan, or a problem with the ductwork. It is important to have a professional inspect your system to determine the cause of the noise and make any necessary repairs.

How can I improve the air quality in my home?

Some ways to improve air quality include using air purifiers, changing the air filter regularly, and ensuring proper ventilation. You may also consider having your ductwork cleaned and sealing any air leaks to prevent pollutants from entering your home.

Why is my energy bill so high?

There can be several reasons for a high energy bill, such as an old or inefficient HVAC system, poorly insulated walls or windows, or a leaky duct system. An energy audit can help identify the cause and suggest ways to reduce energy consumption and lower your bills.

How can I tell if my HVAC system is low on refrigerant?

Low refrigerant levels can cause your HVAC system to malfunction and may indicate a leak in the system. Signs of low refrigerant include insufficient cooling, ice forming on the evaporator coils, and hissing or bubbling noises. It is important to have a professional inspect and repair the system as needed.

Why is my HVAC system not heating/cooling my home properly?

Improper heating or cooling can be caused by issues such as a malfunctioning thermostat, a clogged air filter, or a problem with the system itself. It is important to have a professional diagnose and fix the issue to ensure proper operation of your HVAC system.

How can I tell if my HVAC system needs to be repaired or replaced?

Signs that your HVAC system may need repair or replacement include reduced efficiency, frequent breakdowns, and an increase in energy bills. A professional inspection can help determine the condition of your system and recommend any necessary repairs or replacement.
