What moves the price
01
System size
Oversized units short-cycle and undersized units run constantly; both waste money.
02
Permits and inspections
Most cities require a permit when work touches structure, plumbing, electrical, gas, or the roof deck. Permit fees are usually a small share of the budget, but inspection dates set the pace of the job, so book them into the schedule from day one.
How the ranges are built
These are planning ranges from the Jacob Pro project desk, based on the scopes we price most often. Use them to budget before a site visit. The written estimate a crew lead gives you after seeing the job is the number to plan around.
Questions homeowners ask
When should I replace my AC?
Units older than 12 to 15 years with frequent repairs are usually worth replacing.
Ready for a real number?
A crew lead walks the job and gives you a written estimate. No cost, no obligation.
