Understanding Your HVAC System
Knowing your HVAC system is key for keeping it running right. It has heating, ventilation, and air conditioning parts that work together. This keeps your home comfortable.
Your system uses heating sources like furnaces and boilers for warmth. When it’s hot, air conditioning units and heat pumps cool your home. The ductwork helps air move around, and the thermostat controls the temperature.
Each part of your HVAC system is important for energy use and comfort. Keeping them in good shape helps avoid problems and strange noises. For example, clean air filters help air flow, and checking the system often can catch issues early.
Knowing your HVAC system’s parts and how they work helps you fix noises. This knowledge is great for anyone wanting their system to last long and work well.
