The Science of Staying Warm


How HVAC Systems Beat Fall Chill

As the leaves begin to change colors and the air turns crisp, homeowners across the country prepare for the fall chill. Behind the scenes of the cozy atmosphere lies the science of HVAC (Heating, Ventilation, and Air Conditioning) systems. We will explore the mechanics and technology that enable HVAC systems provided by BRIGGS to combat the fall chill and keep your home warm and comfortable.

Efficient Heat Generation

At the core of any heating system is the process of efficient heat generation. It does not matter if you have a furnace, boiler, or heat pump; the primary objective is to produce heat that can be distributed throughout your home.


A furnace is the go-to heating system for many households, especially those in colder climates. Furnaces generate heat using different fuel sources, including natural gas, oil, or electricity. Adjusting your thermostat to raise the temperature causes the furnace to ignite or heat elements, creating hot air.


Boilers are another standard heating system frequently used in homes with radiant heating or steam radiators. They heat water throughout the home via pipes, radiators, or in-floor radiant heating systems. The heat from the hot water warms the surrounding space.

Heat Pumps

A great energy-efficient option is a heat pump, which both heat and cool your home. They transfer heat from the outside air (or ground) into your home during the heating season. Essentially, they move heat from where it’s abundant (outside) to where it’s needed (inside).

Duct Work

Air Distribution

Heat is generated; it must be evenly distributed throughout your home. This is where the ventilation aspect of HVAC systems comes into play. A blower motor moves the warm air through ducts, eventually releasing it through vents and registers in various rooms.


The ductwork serves as the network of pathways for the conditioned air to travel. Proper design and installation are essential for maintaining the efficiency of the system. Regular inspection and cleaning of ducts are also necessary, as they can accumulate dust and debris, hindering airflow and reducing efficiency.

Smart Thermostats

Modern HVAC systems benefit from the integration of smart thermostats. These devices provide convenience and play a significant role in optimizing energy efficiency.

Remote Control

Smart thermostats allow homeowners to control the temperature remotely, often through a smartphone app. It means you can adjust the thermostat while away from home, ensuring it’s not heating an empty house.


One of the most powerful features of smart thermostats is their ability to create heating schedules based on your daily routine. They use sensors to detect when you’re home and adjust the temperature accordingly. It prevents your HVAC system from running unnecessarily, saving energy and money. 

Energy-Efficient Furnaces

Energy efficiency is a significant focus in the HVAC industry, and modern furnaces are designed with this in mind.

Variable-Speed Blowers Energy-efficient furnaces often feature variable-speed blowers. These blowers can adjust their speed to match your home’s heating needs more precisely. Instead of running at full speed all the time, they can operate at a lower setting when less heat is required, reducing energy consumption.

Sealed Combustion Systems

Some high-efficiency furnaces use sealed combustion systems. Unlike conventional furnaces that draw combustion air from inside your home, sealed systems bring combustion air from the outside. It minimizes heat loss and enhances energy efficiency.

Zoning Systems

Zoning systems offer another level of energy efficiency by dividing your home into different temperature zones. You can control each zone independently, directing heat to specific areas.

Zone Dampers

Zone dampers within the ductwork can open and close to regulate airflow to different zones. This prevents heating empty or seldom-used rooms, further increasing energy efficiency.

Insulation and Air Sealing


The effectiveness of your HVAC system depends on your home’s insulation and air sealing. Proper insulation keeps warm air from escaping while sealing prevents drafts and cold air
