Peter & his team did an excellent job lowering our furnace, hooking up all gas & exhaust pipes, and installing our new tankless water heater. After a stressful underpinning contract, he came in reviewed our project and worked with our duct supplier to complete our project perfectly. We were satisfied with the work, professionalism and promptness. We will be contacting Peter to connect our A/C in the spring. Efharistoume Peter!!
