Understanding the Electrical Components of an HVAC System Every air conditioning system relies on electricity to operate. Electrical current powers the compressor, blower motor, condenser fan, thermostat, safety controls, and many other components that work together to provide cooling. When one electrical component begins to fail, the entire HVAC system may be affected. Problems involving wiring,...

Why the AC Drainage System Is Important Every air conditioning system removes humidity from indoor air as it cools your home. Moisture collected by the evaporator coil drains into a condensation pan before flowing through a drainage pipe and safely away from the HVAC system. When the drainage system functions properly, excess moisture leaves the unit without causing damage. However, if a blockage,...

Why Your Thermostat Is Essential to HVAC Performance Every heating and cooling system depends on an accurate thermostat to maintain indoor comfort. The thermostat monitors room temperatures and communicates with the HVAC system, signaling when cooling or heating is required. When functioning correctly, thermostats help regulate indoor temperatures while improving efficiency and reducing unnecessar...

Understanding the Purpose of an AC Contactor The contactor serves as an electrical switch inside the HVAC system. When your thermostat signals that cooling is needed, the contactor closes to allow electrical power to flow to the compressor and condenser fan motor. Once the desired indoor temperature has been reached, the contactor opens and stops the flow of electricity. Because this process occur...

What Does an AC Capacitor Do? An AC capacitor stores electrical energy and delivers the power required to start and operate important components within an air conditioning system. It helps provide the electrical boost needed for motors to begin operating and supports consistent system performance throughout the cooling cycle. Most cooling systems use capacitors to power the compressor, blower moto...

Understanding AC Leaks An air conditioning system contains several components that work together to provide reliable indoor comfort. When one of these components develops a leak, the entire cooling system can be affected. Water leaks often occur when condensation cannot drain properly from the evaporator coil. Blockages within the condensate hose or drip pan allow water to overflow, potentially da...

Why AC Coils Freeze Your air conditioning system relies on evaporator coils to absorb heat from indoor air. During normal operation, warm air passes across the coils while refrigerant removes heat before circulating it outside through the condenser. When airflow becomes restricted or refrigerant levels drop, the temperature of the evaporator coils can fall below freezing. Moisture in the surroundi...

Why the AC Fan Motor Is So Important The fan motor is one of the most important components of an air conditioning unit. Its primary job is to move air across the condenser and throughout the HVAC system, allowing heat to transfer efficiently and keeping the cooling process operating correctly. Without proper airflow, the condenser cannot release heat effectively, causing the compressor to work har...

Understanding the Role of the AC Compressor The compressor is one of the most important components within an air conditioning system. It is responsible for circulating refrigerant between the indoor and outdoor components, allowing the system to absorb heat from inside the property and release it outdoors. Without a properly functioning compressor, the cooling system cannot complete the refrigerat...

What are the common signs that my boiler needs repair? Several warning signs can indicate your boiler needs professional repair.

Understanding the Role of Refrigerant in an Air Conditioning System Refrigerant, sometimes referred to as coolant or Freon depending on the type of system, is responsible for absorbing heat from inside a building and releasing it outdoors. This continuous cycle allows an air conditioning unit to maintain comfortable indoor temperatures even during periods of extreme heat. Unlike fuel, refrigerant...

Why Your AC System May Not Be Cooling An air conditioning system depends on many components working together efficiently. When one part begins to fail, the entire cooling process can be affected.
