An air handler moves air through your home. It uses a fan to pull air from inside your house. The air passes through filters to remove dust and allergens. Clean air then moves through ducts to different rooms. This process keeps the air fresh and clean.
Temperature Regulation
Air handlers help control indoor temperatures. They work with your heating and cooling systems. In winter, they distribute warm air from your furnace. In summer, they spread cool air from your air conditioner. This ensures your home stays comfortable all year round.
How Furnaces Work
Air handlers and furnaces both circulate air in your home. The furnace heats the air, while the air handler distributes it. Understanding the difference helps in choosing the right system.
Understanding how furnaces work can help you maintain your home’s heating system. Furnaces are a popular choice for heating homes, especially in colder climates. They use a specific process to generate heat and distribute it throughout your home.
Combustion Process
The combustion process is the first step in how furnaces work. It involves burning fuel to create heat. Common fuels include natural gas, oil, and propane. The furnace ignites the fuel in the combustion chamber. This process generates heat. The heat is then transferred to the heat exchanger. The combustion process produces exhaust gases. These gases exit your home through a flue or vent.
Heat Distribution
Once the heat is generated, it needs to be distributed. This is where the heat distribution system comes into play. The furnace uses a blower fan to push heated air through ducts. The warm air travels through the ducts and into your living spaces. This keeps your home warm and comfortable. The thermostat controls the temperature. It signals the furnace to start or stop based on your settings. Proper distribution ensures even heating throughout your home. “`
