Before you call

Four things that make the call shorter

The year the house was built. It tells us more than the model number does.
Whether the thermostat has an EM HEAT or AUX setting. That is the strip-heat question, and it changes the rebate.
Roughly how old the equipment is, or the date on the sticker on the air handler if you can reach it.
Who bills you for water. City of Casselberry or Seminole County — it tells us which building department permits the job.

Attic access & anything else

Faster diagnosis

Find the data plate on the outdoor unit — the sticker with the model and serial number — and text a photo to (689) 308-3675 before we arrive. It tells us the age, tonnage and refrigerant type before our technician leaves the shop, which is often the difference between a repair visit and a repair-or-replace conversation happening on the same call.

No cooling in a house with an infant, an elderly resident or anyone heat-sensitive is a phone call, not a form.

Order of operations — this one costs real money

Book the free Duke Energy Home Energy Check before you replace anything.

Duke Energy requires a free Home Energy Check completed within the previous 24 months to qualify for any Home Energy Improvement rebate. Replace the system first and apply afterwards and the application is denied — there is no retroactive path back.

It is a no-cost visit and it is the single most common way a Casselberry homeowner loses a four-figure rebate. If you are within a year of replacing, book it now, before you call anyone for a quote. Duke’s rebate line is 800.254.8535.
