HVAC FAQs

What does HVAC stand for?

HVAC stands for heating, ventilation, and air conditioning. HVAC refers to the whole heating and cooling system, including furnaces, heat pumps, air conditioning systems, ductwork, thermostats, and indoor air quality solutions like air filtration systems and humidifiers.

Why is my HVAC making noise?

It is normal for HVAC equipment to make some noise while running; however, odd or loud noises like humming, banging, or scraping may indicate a problem with the system. If it is time to replace your HVAC system, give us a call, and we’ll get your home fitted with a quieter, energy-efficient system.

How often should I service my HVAC system?

We recommend twice-yearly maintenance checks on your system, one in the fall and one in the spring. Having an experienced HVAC technician provide regular service helps us catch any potential problems. Bi-annual maintenance helps to prevent high repair costs and high energy bills.

How can I lower my energy bill?

Your utility costs can be reduced by:

  • Seasonal maintenance to ensure your HVAC system is working properly
  • Upgrading to a higher efficiency furnace and air conditioning system
  • Installing a programmable thermostat
  • Keeping curtains drawn during the day
  • Making sure doors, windows, and air ducts are sealed
  • Contact your Sonoma County HVAC company for more energy-saving tips

How often should I change my air filter?

For most air filters, it is recommended to change the air filter every 1-3 months; however, this depends on a variety of factors such as:

  • Air filter model
  • Total indoor air quality
  • Number of pets
  • Household size
  • Local air pollution
  • If you suffer from asthma or allergies

What maintenance can I do as a homeowner on my HVAC system?

To keep your system in good condition, change filters regularly and keep your outdoor unit free of trees, shrubs, weeds, or debris. These simple steps can prolong the life of your system and increase your home’s comfort levels.

What size HVAC do I need?

One of the most important responsibilities of an HVAC professional is to size replacement heating and air conditioning systems accurately. We assess the home, its current system, ductwork, size needs, and more to ensure that the system we recommend is the right fit for your home.

What is the warranty on my HVAC system?

Your equipment’s warranty depends on the make and model; however, most systems have a 10-year warranty covering repairs and replacements. Homeowners should be aware that warranties may be voided due to:

  • Failure to register the warranty
  • Using off-brand replacement parts
  • Improper HVAC installation
  • Lack of annual maintenance
  • Lack of maintenance documentation

To ensure that you are meeting the requirements of your HVAC warranty, lowering your utility bills, and extending the lifespan of your HVAC system, talk to us about maintenance plans.

When should I replace my HVAC system?

Below are a few factors that can help determine if it is time to replace your heating or cooling system:

  • Age of system
  • Frequency and cost of repairs
  • Increased utility bills
