Who We Are

High Performance Home is a Veteran Owned, Certified, Fully Licensed and Insured Home Performance Contractor specializing in making homes more energy efficient, comfortable, and healthy. Founded in 2008 by Larry Tennant, High Performance Home has a proven track record of providing cost effective solutions which have improved the efficiency and comfort of many Maryland homes.

Why We’re Different

When you contact High Performance Home, you’ll be speaking directly with the owner of the company. Larry Tennant will be your point of contact from start to finish on your energy audit and any work we perform. You will never get a lengthy sales pitch or high-pressure sales tactics from us. Our goal, our mission really, is to provide you with performance based, cost effective solutions and let you decide what, if anything is worthwhile to do. You are not handed off from a marketing outfit to a salesperson, to a project manager, to a supervisor, and on and on and on. Honesty, integrity and customer service are the backbone of our company and go into every project we do. And as a participating Contractor in BGE and Potomac Edison the Home Performance with Energy Star Program’s the work we do can qualify for up to $7500 in Rebates!

Larry Tennant, Owner & General Manager

Larry is the Owner and General Manager of High Performance Home. He also wears many other hats such as Energy Auditor, Project Manager, Supervisor and when needed laborer. Larry started his construction career in 1977 after honorably completing his military service in the U.S. Army. Over the course of 40 years in construction Larry has worked from the ground up – from laborer to carpenter to project manager of multi-million dollar projects for a large construction company, to his lifelong dream of owning and running his own business. Larry is a hands-on owner who believes in doing what he says and providing customers with superb customer service and a pleasurable experience. Larry has 3 children and 5 grandchildren and his greatest pride is his family.
