What Matters Most
Ductwork condition matters as much as the unit itself. Leaky ducts waste 20-30% of heated or cooled air before it reaches your rooms.
Pro Tip
Look for contractors who offer duct testing as part of the installation. This identifies hidden leaks that undermine new system performance.
Common Mistake
Skipping the maintenance plan. New HVAC systems need annual tune-ups to maintain efficiency and warranty coverage.
Best Time to Buy
Emergency replacements in mid-summer or mid-winter cost 15-25% more due to rush scheduling and limited equipment availability.
