HVAC Transformer
A transformer transforms electrical energy from one alternating-current circuit to another or multiple current circuits. It is used in low-voltage devices to reduce the voltage of conventional power circuits. Transformers change voltage using electromagnetic induction. Current is generated in a secondary winding as magnetic flux lines build up and collapse with changes in electric current traveling through the primary coil.
HVAC Condenser Coil
Condenser Coil Replacement in Air Conditioner Unit What is the use of a condenser coil? The compressor unit increases the pressure on the refrigerant gas. Condenser coils condense the gas, and gas is converted into the form of liquid. It contains liquid from the refrigerant.

Air conditioner not turning OFF: The thermostat controls the fan setting in the air conditioner cooling process. Failed thermostat sometimes...
HVAC Compressor
How to Replace a Bad compressor in an air conditioner? Is your air conditioner compressor facing a gas leakage problem or any other problem? Then you are on the right page to know more details about it. This article provides a few facts about compress gas leakage and other issues with compressor replacement methods. How does the compressor work in the air conditioner? The compressor is boarded in the condenser unit. It compresses the gas refrigerant. This compression process increases the temperature and pressure of the gaseous refrigerant. The high-pressure refrigerant converts into liquid form in the condenser unit. Why does the compressor coil fail?  Overheating of Compressor:  Never install your compressor in direct sunlight. Sunlight overheats your compressor, and overheating fails the compressor.  An insufficient ventilation system does not release heat sufficiently, and heat increases in the compressor.  Also, continuous use or high voltage supply...

HVAC Furnace Parts
HVAC Thermocouple
How to repair and replace a thermocouple in the Furnace? What is Thermocouple? The thermocouple is a necessary part of the furnace in terms of security. A thermocouple is a small, continually burning flame. It is commonly used in the gas furnace with a standing pilot. The thermocouple's top is situated in the flame to ensure that the tip is always warm.  When the pilot flame goes out, the thermocouple automatically shuts off the gas valve in the furnace. That's why your thermocouple must be in good condition. If it failed, then replace it with new thermocouple replacement parts. What distinguishes a thermocouple from a flame sensor? Thermocouples are commonly found in older furnaces. However, new installations are now mandated to use electronic fuel injection furnaces.  Flame sensors use electronic integrations instead of standing pilot lights, and thermocouples use standing pilot lights. Flame sensors ignite only when needed. Metal probes and brackets are used in...
