Your HVAC system is one of the largest investments you'll make for your home.
Central air uses furnace and AC with ductwork. Heat pumps provide both heating and cooling efficiently. Ductless mini-splits offer targeted heating/cooling without ductwork. Geothermal systems exploit underground temperature stability.
SEER measures AC efficiency (higher is better, minimum 13). AFUE measures heating efficiency (modern furnaces are 90-98%). Higher efficiency costs more upfront but saves on energy bills.
Undersized systems can't maintain comfort; oversized systems cycle on and off wastefully. Professional Manual J load calculations are essential.
Cold climates need high-efficiency furnaces. Hot climates prioritize high SEER ratings. Moderate climates make heat pumps attractive.
Even premium equipment performs poorly with improper installation. Choose contractors with excellent certifications and warranties. Poor installation reduces efficiency by 15-25%.
