HVAC Installation Atlanta

Installation & Replacement

Every HVAC installation Atlanta property needs is sized to the building, not a rule of thumb. We run a real thermal load calculation, every time.

Overview

An oversized system short-cycles, never dehumidifies and wears itself out. An undersized one runs non-stop and never catches up. Both are the result of the same shortcut: eyeballing the tonnage. Westmark runs a real thermal load calculation on every installation, square footage, insulation, glazing, orientation, occupancy and duct condition, then specifies equipment that matches it.

What's Included

Exactly what we do on a installation & replacement visit.

01
Thermal load calculation

Room-by-room heat gain and loss analysis before we recommend a single piece of equipment.

03
Correct line-set practice

Brazed joints, nitrogen purge, deep vacuum evacuation and verified micron level, the steps most installers skip.

Duct & airflow correction

Undersized returns and leaking trunk lines corrected so the new system can actually perform.

Startup commissioning

Charge weighed in, airflow set, temperature split verified and results documented.
