To effectively maintain your rooftop units, it’s essential to understand their key components: Phoenix Air Conditioning Repair Ac Repair Man Near Me 24 Hour Air Conditioning Service Near Me Air Conditioning And Heating Services

• Compressor: The heart of the system, the compressor circulates refrigerant, the fluid responsible for cooling or heating the air.
• Condenser Coil: This coil dissipates heat from the refrigerant, typically located outside the building.
• Evaporator Coil: This coil absorbs heat from the air inside the building, cooling it down.
• Blower Motor and Fan: These components circulate air throughout the building.
• Filters: These filters remove dust, dirt, and other particles from the air, protecting the internal components and improving air quality.
• Dampers: These adjustable flaps control the flow of air, allowing for ventilation and temperature regulation.
• Refrigerant Lines: These lines transport refrigerant throughout the system.
• Electrical Components: These include wiring, control boards, and safety devices that regulate the unit’s operation.
