HVAC FAQs 

Residential Air Conditioning & Heating

What does “HVAC” mean?

HVAC is an abbreviation for heating, ventilation, and air conditioning. The term covers a broad range of air conditioning and heating systems including units, ducts, and filters.

Why do my ducts make sounds when the furnace starts?

This commonly indicates an issue of undersized ducts. It could also signify air flow that is too powerful for the existing ducts, which needs to be calibrated. Inspection by trained experts can help to determine the definitive cause.

Why would I want regular maintenance on my air conditioning or heating system?

Your home climate system is an investment. Allowing issues to develop and worsen can increase the eventual cost of repairs while reducing your home’s air quality. Regular annual maintenance helps you prepare for future upgrades or repairs while keeping peak performance in the meantime.

What Is R-22 refrigerant?

If your building retains an HVAC unit from prior to 2010, it likely utilizes R-22 refrigerant.
