Wine Room & Cellar Refrigeration in Leander, Texas | Coats Mechanical LLC

A wine collection is only as safe as the room that holds it. Bottles need a stable temperature around 55°F and relative humidity near 60–70% to age properly, and a standard household air conditioner cannot hold those conditions — it dries the air out and cycles too widely. Coats Mechanical LLC installs and services dedicated wine room refrigeration systems for homeowners, restaurants and retailers across Leander and Central Texas.

Every project starts with the room itself. We evaluate insulation, vapor barriers, glass walls, door seals and the heat load from lighting and adjacent spaces, then size a cooling unit that matches it. Depending on the layout, that may be a through-wall self-contained unit, a ducted system that keeps noise and equipment out of the cellar, or a split system with a quiet evaporator inside and a condenser outdoors.

Our refrigeration background matters here. Owner Shad Coats has spent 20 years working on commercial and industrial refrigeration, so wine cellar equipment — compressors, evaporator coils, expansion valves, humidity controls and condensate management — is familiar territory. We handle new installs, retrofits of rooms that never cooled correctly, and repairs on major wine cooling brands.

When a cellar unit fails, time matters. Rising temperatures and swings in humidity can push corks, accelerate aging and put a valuable collection at risk. We diagnose the root cause, explain the options plainly, and give you upfront pricing before any work begins. Ongoing maintenance — coil cleaning, drain checks and control calibration — keeps the system quiet, efficient and dependable year after year.
