Yellowhammer HVAC

Heating and cooling across Alabama

A free connecting service linking homeowners with local heating and cooling providers. Describe the system and what it is doing, and you will be pointed to someone who covers your area.

The coldest air in the house crosses the hottest room. What happens up there decides the summer. 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 — The season’s odometer — a hundred cooling days pass through it.
  2. 2 Return and filter — The lungs, and the first thing a retrofit house sized too small.
  3. 3 Air handler and furnace — Up in the attic, asleep nine months, asked for everything in December.
  4. 4 Coil and condensate drain — Litres of Gulf moisture a day, all leaving through one narrow line.
  5. 5 Attic ducts — The coldest air in the house, commuting through the hottest room on the property.
  6. 6 Outdoor unit — Full sun, full load — where August culls capacitors by the thousand.

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 river basins, 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.
