Knowing the major components and how they work helps you troubleshoot issues early and communicate clearly with your contractor.

• Core components:

• Air conditioner: Compressor, condenser coil, evaporator coil, refrigerant lines, blower, and thermostat working in harmony to move heat out of your home.

• Furnace: Heat exchanger, burners, igniter, gas valve, control board, and blower to deliver warm air safely and efficiently.

• Heat pump: Functions like an AC in summer and reverses to heat in winter—highly efficient in moderate climates.

• Air handler: Circulates conditioned air, especially in heat pump systems.

• Ductwork: The highway for conditioned air; leaks and restrictions can waste 20–30% of energy.

• Thermostat: The brains of comfort control, now often smart and Wi‑Fi enabled.

• Ventilation and filtration: Filters, fresh-air intakes, ERVs/HRVs for balanced airflow and indoor air quality.

• Efficiency terms you’ll see:

• SEER2/EER2: Cooling efficiency; higher means more efficient AC and heat pumps.

• AFUE: Furnace efficiency; 90–98% AFUE means nearly all fuel becomes heat.

• HSPF2: Heat pump heating efficiency.

• MERV: Filter rating for particle capture; MERV 8–13 is typical for homes.

• Why this matters: Understanding the basics helps you: 1) Identify when performance is slipping, 2) Ask smarter questions, 3) Decide when repair vs. replacement makes sense.

Pro tip: If you’re experiencing uneven temperatures room to room, the culprit is often airflow or duct design—not the equipment itself.

FAQs: Quick Answers for Fast Decisions
