AC Installation in Jasper, GA

Thirty-eight free-flow minutes north, in the one county here that the enforced energy code puts in a different climate zone. That has a very specific consequence for one setting on your thermostat.

The switchover setting is the most expensive number in the house

On a dual-fuel system, the switchover temperature decides at what outdoor temperature the heat pump stops and the furnace takes over. The figure most commonly used as a default — and it is genuinely a national default rather than a recommendation for anywhere in particular — sits around thirty-five degrees. Up here that default is left in place constantly, and it is close to the worst possible setting: a correctly sized modern heat pump at this county's design temperature still has real capacity well below it, so a system switching at the default hands the whole load to the expensive fuel while the cheap half of the machine is still working. Nobody publishes a balance point for this climate zone, and we are not going to pretend one exists. What we do is calculate yours — the load against the equipment's published capacity at the local design temperature — and set the switchover to it, then tell you what we set and why. It is a five-minute conversation that is worth more than most of the equipment upgrades on a quote.

The same thing is true wherever you are

New equipment on a bad duct system reproduces the complaint you already have at a higher price. Static pressure takes twenty minutes to measure and it decides whether a replacement will actually fix what you called about, so we measure it before we quote equipment rather than after you are unhappy. And one thing we will not do: tell you how many years your new system will last. There is no authoritative published service-life figure for this equipment — none, from anybody — so every number you have been quoted for that was somebody's estimate wearing a lab coat. What we can tell you is what we found, what we measured, and what the manufacturer's terms actually say.

Questions people ask

  • How long does a straight changeout take?

    One day for a single system with no duct modification, usually eight to ten hours. If the plenum has to be rebuilt, the line set replaced through a finished ceiling, or the electrical service touched, it goes to two days and we tell you that before you sign.

  • What actually changes the price?

    Duct modification, line-set replacement versus flush-and-reuse, electrical upgrades, code corrections the inspector will look for, a second system, and how hard the equipment is to get to. The published range below covers a straight replacement and says what it excludes.

  • Can you reuse my existing line set?

    Sometimes. It depends on the diameter against the new equipment, its condition, and what refrigerant ran through it. A line set that carried a burned-out compressor's acid should not carry a new one. We flush and pressure-test it, or we replace it, and we tell you which before we quote it — not after we open the wall.

  • Do I need a permit?

    Yes. There is no state permit requirement in Georgia — the state deletes the administrative chapter that would create one — but every jurisdiction we work in requires a mechanical permit for equipment replacement, and the permit is in our price. In Cherokee County it is a flat mechanical service permit issued only to state-licensed technicians.

  • What does the warranty actually cover?

    The parts warranty is the manufacturer's, not ours, and its length depends on registration. Read the registration terms below — the number people quote and the number you get are two different things unless somebody files the paperwork.
