System replacement

A replacement starts with a calculation rather than with whatever size is up there now. The box on the wall saying three tons is not evidence that the house needs three tons, and half the systems we take out were wrong on the day they went in.

What a new AC system costs in Pinellas County

From measurement to start-up

  1. 01Measure the house, not the old unit

    The rooms set the tonnage. The size of the old unit proves nothing.

  2. 02Look at what the air has to move through

    If the duct cannot carry the new system, you hear that before anything is ordered.

  3. 03Price the whole job

    Equipment, coil, line set, pad, disconnect, permit and start-up, all on one figure.

  4. 04Pull the permit and swap it

    A day for a straight changeout, longer where the attic was framed around the old unit.

  5. 05Charge it and prove it

    Refrigerant weighed in, static pressure and temperature split measured, and the readings written on your paperwork.

Questions about replacing a system

Can I replace it with the same size?

You can, and it is how most wrong systems get installed. Houses gain windows, insulation and extensions. The calculation takes half an hour and it is the only thing that answers this.

Is a bigger system better?

No. An oversized system chills the air quickly, switches off before it has pulled any humidity out, and leaves you cold and clammy. The short cycling wears the compressor as well.

Do I need a permit for a straight swap?

Yes, and the inspection that follows is the part protecting you rather than us. A changeout done without one is invisible until you sell the house.

The size first. The price after it.

Forty minutes in the house, measured room by room, and the size on paper before anyone talks about equipment.
