A/C REPAIR, SERVICE, AND REPLACEMENT

Welch Mechanical keeps residential and light commercial clients cool and comfortable throughout the summer months. There’s no job too tough for Owner Glen Welch to tackle because he focuses on providing exceptional customer service.

Timely-High Quality Cooling Service

Serving properties throughout Columbia County, most of Greene County, and Rensselaer, NY, call on us when you need repairs to your air conditioner system.


Stifling heat is terrible for everyone, especially senior citizens and very young children and pets. Turn to Welch Mechanical for our emergency services if your A/C breaks down turning the night, weekend, or holiday.


We value our clients and strive to achieve complete customer satisfaction on every job we undertake. Glen is on every job, and it’s not completed until he gives his stamp of approval.
