Marshall Mechanical is an experienced heating, air conditioning and plumbing contractor serving the Richmond area for both residential and commercial customers.

Founded by owner and president, Sean Cantrell — a licensed professional engineer and former mechanical engineer for Baskervil, Marshall Mechanical has been serving Richmond since 2005 and our staff members have an average of 17 years experience each in their respective areas.
Marshall Mechanical serves the entire Greater Richmond area including the city of Richmond and the counties of Chesterfield, Goochland, Hanover, Henrico, Powhatan and New Kent. Our offices are centrally located near Powhite Parkway and West Broad Street, making it easiest to serve the Richmond and the surrounding counties from one office location.

We are an authorized promotional dealer of Lennox products which we feel are the best quality and incorporate highly innovative technology that other manufacturers don’t. And their service and warranties are excellent.
We are also an authorized dealer of WaterFurnace geothermal heating and cooling systems. WaterFurnace has been around the longest of geothermal manufacturer, have sold more product than any other and has a trusted name and excellent track record. We enjoy our relationships with both Lennox and WaterFurnace.
Oh, and we have tons of experience in fixing situations where other HVAC, plumbing or geothermal contractors have failed. We don’t want to tell you those stories but we do always wish the customer would have called us first, as we could have saved them from a great deal of stress and eliminated a few headaches.
That seems to have been especially true of geothermal system installation in the last year, as not all contractors have the deep level of expertise that Marshall Mechanical brings to the table.

There are a lot of resources here including our special offers, complete details of all Lennox products with downloadable PDF brochures, a regularly updated blog, and advice column with glossary of HVAC and geothermal terminology.
