Yellowhammer HVAC

HVAC companies in Alabama

Most of the difference between two HVAC quotes is not the equipment. It is the loop around it — the sizing, the ducts, the lines, the commissioning — and whether anyone measured before they priced.

What separates a complete quote from a cheap one

  • Load calculation — done on your house, or copied from the old unit? Oversizing is this climate’s costliest habit.
  • Ductwork — assessed and sealed, or inherited as found? Around here the ducts live in a baking attic, and so do their leaks.
  • Line set — replaced, or reused with the old system’s oil and debris in it?
  • Commissioning — charge and airflow set by measurement with the numbers in writing, or « it’s blowing cold »?
  • Warranty — the manufacturer covers the box; the shop covers the installation. The second is worth more.
The coldest air in the house crosses the hottest room. What happens up there decides the summer. Six of them, numbered. Five are the loop; only one is the box.

  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.

The work

Why systems struggle in this region

Gulf air gives every Alabama air conditioner a second job, and a cooling season that runs April into October spends equipment hours faster than almost anywhere. The ducts overhead cross attics that bake all summer, the furnaces sit forgotten for nine months, and whole subdivisions carry same-year builder equipment aging in unison. Most of what gets reported here is predictable.
