What Is the $5000 Rule for Air Conditioner Replacement?

We don’t publish a specific “$5,000 rule.” Some homeowners use a “repair cost × system age” rule of thumb to decide repair vs. replacement, but the right choice requires an on-site diagnostic. Our tech will assess age, odd noises, smells, airflow, air quality, rising energy bills, and repair frequency, then present options with upfront pricing. We offer an $89 A/C Install Diagnostic with a Next Day Guarantee, and the diagnostic charge is waived with service. Phoenix-area customers may qualify for APS $200 or SRP up to $1,125 rebates.
