The $5,000 Rule

Industry pros use a simple test to decide whether to repair or replace a heating or cooling system. Multiply the age of your unit by the cost of the repair. If the number is over $5,000, replacement is usually the smarter long‑term move. Under $5,000? Repair it and keep it running.

The average HVAC repair runs around $5,000 over a system's lifetime — and we'll always give you a free, no‑pressure second opinion before you spend a dime.
