Our Story

Keeping Northern Virginia homes
comfortable and safe

Kelvin Services LLC has been keeping Northern Virginia homes comfortable since 2016. We started in Alexandria, VA, with a straightforward goal: give homeowners one reliable company to call when their heating or cooling system needs attention. That focus has not changed.

Our team brings more than 25 years of combined technical experience to every job. That depth shows in how we work. We diagnose problems accurately, explain your options in plain language, and fix things right the first time. No runaround, no upsells you do not need.
