Here’s a simplified guide to HVAC basics:
What is HVAC?
Heating, Ventilation, and Air Conditioning
Three Main Functions:
1. Heating: Warms up spaces
2. Ventilation: Moves air, removes stale air
3. Air Conditioning: Cools down spaces
Key Components:
1. Furnace/Boiler (Heating)
2. Air Handler/Blower (Ventilation)
3. Compressor/Condenser (Air Conditioning)
4. Thermostat (Controls temperature)
5. Ductwork (Air distribution)
How HVAC Works:
1. Air is drawn into the system
2. Heated/Cooled by furnace/condenser
3. Distributed through ductwork
4. Ventilation removes stale air
5. Process repeats
Types of HVAC Systems:
1. Split System (separate units for heating/cooling)
2. Package Unit (single unit for heating/cooling)
3. Heat Pump (heats/cools using refrigerant)
4. Central Air Conditioning (whole-house cooling)
HVAC Terms:
1. BTU (British Thermal Unit): Measures heating/cooling capacity
2. SEER (Seasonal Energy Efficiency Ratio): Measures AC efficiency
3. AFUE (Annual Fuel Utilization Efficiency): Measures heating efficiency
4. MERV (Minimum Efficiency Reporting Value): Measures filter efficiency
Basic Troubleshooting:
1. No heat/cool: Check thermostat, power, and filters
2. Leaks: Inspect ductwork, connections
3. Noise: Check fan, compressor, and bearings
Maintenance Tips:
1. Change filters regularly
2. Clean condenser coils
3. Inspect ductwork annually
4. Schedule professional maintenance
Energy-Saving Tips:
1. Adjust thermostat settings
2. Use programmable thermostats
3. Upgrade to energy-efficient systems
4. Seal air leaks
