Frequently Asked Questions

How often do I need to change my air filters?

Air filters are your primary protection against dust and debris that can affect your overall indoor air quality. Allergens and contaminants, for example, can pose a health hazard to your family members with asthma or other respiratory diseases. To maintain good indoor air quality, you should replace air filters at least once a month, depending on how often you use your HVAC system. Factors such as having pets and the overall size of your home or business also affect how often you should change your air filters.

Should I clean my air ducts?

Regular air duct cleaning is as important as regular HVAC cleaning. Keeping your air ducts clean prevents the buildup of dust and other air contaminants in your air duct system. A licensed HVAC repair, installation, and maintenance service provider use heavy-duty tools and equipment to clean your air ducts thoroughly. Get your air ducts cleaned by a professional at least once every two years.

What is the summer and winter switch used for?

Some HVAC systems usually have a summer and winter switch connected to the furnace. If switched to winter mode, the air can pass through the furnace, providing humidity and warmth throughout your home. When switched to summer mode, air bypasses the furnace as indoor air is more humid during summer.

What is a ductless AC system?

A ductless AC system does not need ducts to circulate air throughout your home. Instead, it consists of an outdoor and indoor unit. The outdoor unit consists of a condenser connected to the indoor unit via a flexible pipe. A ductless AC system is ideal for isolating air conditioning in certain zones. A ductless furnace works similarly.
