🔧 Key HVAC Components
Thermostat
Control center that monitors temperature and signals system to heat/cool as needed
Air Handler
Indoor unit containing blower that circulates conditioned air through ductwork
Evaporator Coil
Absorbs heat from indoor air; contains refrigerant that evaporates as it cools
Condenser Unit
Outdoor unit that releases heat absorbed from home into outside air
Compressor
Heart of AC system; pressurizes refrigerant to move heat from inside to outside
Furnace
Heating unit that burns fuel (gas/oil) or uses electric elements to warm air
Heat Exchanger
Metal chamber in furnace that transfers heat from combustion to circulating air
Ductwork
Network of passages that deliver conditioned air throughout your home
Air Filter
Removes dust, pollen, and particles from air; protects system and improves air quality
📖 Essential HVAC Terms Homeowners Should Know
- BTU (British Thermal Unit): Measure of cooling/heating capacity
- Tonnage: Cooling capacity (1 ton = 12,000 BTU/hour)
- SEER2/SEER: Seasonal Energy Efficiency Ratio for cooling
- HSPF2/HSPF: Heating Seasonal Performance Factor for heat pumps
- AFUE: Annual Fuel Utilization Efficiency for furnaces
- Refrigerant: Chemical that transfers heat in cooling systems

⚡ SEER2 Ratings: What You Need to Know
SEER2 (Seasonal Energy Efficiency Ratio 2) measures cooling efficiency. As of 2023, this updated testing standard replaced SEER. Higher numbers mean better efficiency and lower operating costs.
Standard Efficiency
Meets minimum requirements; good for budget-conscious buyers
High Efficiency ⭐
Best value; qualifies for rebates and tax credits
Premium Efficiency
Maximum savings; ideal for hot climates with heavy AC use
💰 Energy Savings Example
For a 2,000 sq ft home in a hot climate running AC 6 months/year:
14 SEER2 System
$1,200/year
16 SEER2 System
$1,050/year
Save $150/year
20 SEER2 System
$840/year
Save $360/year
🔥 AFUE (Furnace Efficiency)
Annual Fuel Utilization Efficiency measures how much fuel converts to heat:
- • 80% AFUE: Standard efficiency (81% minimum by law)
- • 90-95% AFUE: High efficiency condensing furnaces
- • 96%+ AFUE: Premium efficiency; maximum savings
♨️ HSPF2 (Heat Pump Heating)
Heating Seasonal Performance Factor 2 rates heat pump heating efficiency:
- • 7.5 HSPF2: Minimum standard
- • 8-9 HSPF2: Good efficiency
- • 10+ HSPF2: Excellent cold-climate performance
📍 Regional Minimum Efficiency Standards (2025)
| Region | States | AC Minimum | Heat Pump Minimum |
|---|---|---|---|
| North | Most northern states, Midwest | 14 SEER2 | 15 SEER2 / 8.8 HSPF2 |
