What Is HVAC? Everything You Want To Know

A furnace is probably the best choice for larger homes or those in cold regions that need a more consistent heating system for the whole house. Furnaces are made up of several different components in Blackhawk Supply for example that keep your home or commercial space warm all winter long. First, there are the burners that bring fuel to the boiler and burn it for heat. There are also heat exchangers, a fan, and a flue that work together to send heated air through the ducts and to all rooms in your home.


Although ventilation isn’t related to the air temperature in your home, it has everything to do with air quality. Proper ventilation can help restore much-needed oxygen levels in your home and eliminate bad odors from pets, cooking, smoking, or simply stale air. It’s also essential to keep humidity levels low and filter out carbon dioxide, which helps keep the air in your home fresh and clean.

Entry and exit points to your home, such as doors and windows, are convenient for natural ventilation, but this is not a good option in some cases. In the dead of winter, you probably don’t want to leave windows or doors open for more than a minute or two. Airtight homes or commercial areas also do not allow too much ventilation and focus more on energy efficiency systems that reduce air leakage, keeping the air in these buildings inside to reduce energy costs and waste.

This is why mechanical ventilation systems are so important in these buildings, to ensure the renewal of air necessary for healthy and breathable air. These systems such as dwyer sensors for example start with a specially designed air intake unit to bring outside air into your home. This air then passes through a filter to remove dirt, allergens, and other particles. This air is used in heating and cooling systems, adjusting the temperature of your home as needed while reducing humidity.

If you are using a central heating, cooling, or combination system, the air is then sent through your home’s ductwork to different areas of your home or commercial building. This keeps the air clean and fresh, heated or cooled to the perfect temperature for your comfort.

What Does “HVAC Certified” Mean?

If you’ve never heard this term before, you might wonder if your system falls into this category. So what is the

HVAC certified? This means your HVAC system is installed and serviced by a licensed HVAC technician. These technicians have passed the necessary exams to obtain their certified licenses. Exams for this certification vary depending on where you live, and federal certification may be required to become a certified HVAC technician.
