Repair or Replace? How to Decide When Your HVAC System Is Aging

It's the question every homeowner eventually faces: sink another few hundred dollars into an aging system, or invest in a new one? Here's the honest math we walk customers through.

The 5,000 rule

Multiply the age of the unit by the repair cost. If the result is over $5,000, replacement usually makes more sense. A 12-year-old furnace needing a $500 repair scores 6,000 — time to talk about replacement.

Refrigerant matters

Older AC systems using R-22 refrigerant are expensive to recharge because R-22 is phased out. If your system uses it and develops a leak, replacement is almost always the right call.

Energy savings are real

A new high-efficiency furnace or AC can cut heating and cooling costs by 20–40%. In Utah's climate — hot summers, cold winters — that adds up fast.

Comfort counts too

Uneven temperatures, constant cycling, and humidity problems often mean the system was never sized right or is simply worn out. A new properly-sized system fixes comfort problems repairs never will.

Not sure which way to go? Levao gives upfront quotes for both repair and replacement so you can compare with real numbers. Call (801) 300-8132 — no pressure, no commissioned upsells.
