The swamp cooler conversion process and timeline
What happens from your first call to the final inspection.
Quick answer: A conversion runs in seven steps: request a quote, in-home assessment, written quote, permit and scheduling, installation, start-up testing, and inspection. Install time varies with ductwork and electrical work, and your contractor sets the schedule in the quote.
Step by step
- Request a quote. Send the form or call. Tell the contractor about the home, the current cooler, and your timing.
- In-home assessment. The contractor inspects the home, existing ducts, roof or wall opening, electrical panel, and outdoor unit location, and sizes the system.
- Written quote. You receive an itemized quote covering equipment, ducts, electrical, permit, removal of the swamp cooler, and warranty.
- Permit and scheduling. After you approve, the contractor handles the permit and schedules the work.
- Installation. The old cooler comes out, the opening is sealed, equipment is set, ducts and return air are connected, electrical and refrigerant lines are completed.
- Start-up and testing. The contractor starts the system, checks airflow and refrigerant charge, and tests the thermostat.
- Inspection and walkthrough. The permit inspection is completed, the contractor shows you the system, and you receive warranty paperwork.
Frequently asked questions
How long does it take to convert a swamp cooler to refrigerated air?
Your contractor sets the schedule with the quote. Many straightforward swaps are completed in a few days, and extra duct or electrical work adds time. Treat that as a general expectation, not a promise.
Will I be without cooling during the conversion?
Often your swamp cooler keeps running until install day. Ask the contractor how they plan to minimize downtime in hot weather.
What should I do to prepare?
Clear access to the attic, roof hatch, and outdoor unit location. Move furniture away from vents and returns. Make sure someone can answer questions on install day.
When is the best time to convert?
Contractors are busiest in summer. Planning in late fall through early spring usually makes scheduling easier, but your contractor can tell you what is open.
