HVAC contractor serving Ashburn, VA since 2016

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.

We handle the full range of HVAC work for residential homes. That includes AC installation and repair, heating system installation and repair, and scheduled maintenance for both heating and cooling equipment. Whether your system stopped working on the hottest day of the summer or you want a tune-up before winter hits, we are ready to help.

From Ashburn and Leesburg in the west to Woodbridge and Lorton in the south, and across Arlington, Fairfax, Alexandria, Reston, and the communities in between, we serve homeowners throughout Northern Virginia. If you live in this region, there is a good chance we have worked in your neighborhood.

What sets us apart is simple: we treat every home like it is our own. We show up on time, communicate clearly, and stand behind our work. Our business hours run Monday through Friday from 7 a.m. to 9 p.m., Saturday from 8 a.m. to 6 p.m., and Sunday from 8 a.m. to 5 p.m., so you are not stuck waiting until Monday when something goes wrong over the weekend.
