When it’s time to replace your furnace, AC, or heat pump

Heating and cooling is the most expensive system in most homes, so a repair-or-replace call carries real money. ENERGY STAR gives clear age markers to start the conversation.

Consider replacement once a heat pump or air conditioner is more than 10 years old, or a furnace or boiler is more than 15 years old. Watch for frequent repairs paired with rising energy bills, plus uneven temperatures, odd noises, or excess dust — all signs of a system in decline.

Replacing well-aged equipment with an ENERGY STAR certified unit can cut heating and cooling costs up to 20 percent when installed correctly. Confirm current pricing and rebates locally, since HVAC costs vary by region and equipment.

This kind of work is pro territory — refrigerant, gas, and high voltage — so the win is knowing what failed and whether age justifies replacing before the quote lands. OwnWise helps you frame that decision and sanity-check the repair-versus-replace math.
