Yellowhammer HVAC

Heating and cooling across Alabama

A free connecting service linking homeowners with local heating and cooling providers across Alabama. What follows is what an attic at summer temperature does to a system, and what a complete quote should cover.

A hundred days of load find the weakest link. It is almost never the box out in the yard. Six places a system gives way. The one everyone blames is No. 3, the box; the loop around it does most of the failing.

  1. 1 Thermostat. Where the season’s mileage actually accumulates.
  2. 2 Return and filter. Undersized in half the retrofits, and the reason the far room never cools.
  3. 3 Air handler and furnace. The part of the system Alabama barely uses, and almost never checks.
  4. 4 Coil and condensate drain. Liters of Gulf moisture a day, all leaving through one narrow line.
  5. 5 Attic ducts. Conditioned air, routed through the hottest space in the building.
  6. 6 Outdoor unit. Where a Gulf-coast August decides which capacitors see another summer.

A system rarely fails where you think

The equipment gets the blame; the loop around it (the ducts, the airflow, the controls, the drain) does most of the failing. That is why the first useful question about any comfort problem is not what the box is doing, but what is around it.

The work

Sixteen cities, three regions, one summer

From the Shelby County plats to Huntsville’s rocket-era ranches, from the Coosa at Wetumpka to the mill blocks of Opelika: sixteen cities working through the same hundred-day summer and the same first cold snap.
