What is HVAC?
Commercially used HVAC involves frequent repairs and requires licensed contractors to have expertise with the equipment. HVAC consists of three main parts.

• Heating
• Ventilation
• Air Conditioning

All these parts perform specific functions and help to regulate indoor temperatures, air quality, and humidity. Heating consists of gas/electric furnace that withdraws the warm air from outside and brings it to the evaporator coils.
Here is a breakdown of HVAC equipment that needs cautious attention:

Thermostat:

• Achieving accurate readings and making sure calibration is done correctly.
• Energy savings settings are set properly.
• Batteries are to be changed after a regular, recommended inspection.

Furnace:

The furnace oversees heating centrally using numerous fuels, including natural gas, and oil.

• The burner assembly is required to be cleaned.
• All safety controls involving flame and switch censors are tested properly.

Air Conditioner:

Air conditioners regulate cooling just through thermostats, transporting heat from indoors to outdoors.

• Ensure all obstructions, like grime and debris, are cleared from condenser coils.
• The refrigerant level must be maintained to avoid impaired cooling.
• Precise thermostat setting for efficient functioning.

Air Handler:

The air handler is a crucial component for the cooling and heating systems. Ducts distribute conditioned air over the structure.

• The blower assembly and evaporator coil must be cleaned for efficient performance.
• The condensation pans and drain lines are properly emptied.
• An appropriate enclosure for the air handler cabinet is essential to avoid the growth of mold and moisture.

Evaporator Coils:

Smoothly working refrigerants are important for recirculating air. The vaporized coil takes the heat from indoors, leaving the cool air inside the building.

Exhaust Fan:

An exhaust fan assists in removing moisture, pollutants, and odors from indoor air. Hence, tidy fans are essential to maintaining healthy air quality.

Hence, each component of HVAC functions together, ensuring effectiveness, durability, and safety through routine inspections.
