Understanding the Problem: Why Is My AC Blowing Hot Air? 24 Hour Ac Company 24 Hour Heating And Cooling Service Near Me Heater Repair Services
Before you start troubleshooting, it’s essential to understand the basic principles of how an air conditioner works. AC units operate on a refrigerant cycle. This cycle involves a refrigerant absorbing heat from the air inside your home and releasing it outside. The key components involved in this process include: Emergency Heating Repair Near Me Hvac Repair Contractor Ac Unit Replacement Near Me
- Compressor: The heart of the AC system, the compressor pressurizes the refrigerant, raising its temperature.
- Condenser Coil: Located outside, the condenser coil releases the heat absorbed by the refrigerant.
- Evaporator Coil: Located inside your home, the evaporator coil absorbs heat from the indoor air, cooling it.
- Refrigerant: A special fluid that absorbs and releases heat.
- Expansion Valve: Controls the flow of refrigerant.
- Fan Motors: Fans that circulate air over the condenser and evaporator coils.
When any of these components malfunction, it can disrupt the refrigerant cycle and lead to the AC blowing hot air. The following are some of the most common culprits: 24 Hour Emergency Heating Service Ac Repair Companies Hvac Air Conditioning Service
