What a great team! We really enjoyed being treated like the only customer, despite knowing you are extremely busy. Very professional!

I met Jeff at the house and saw he was neat, clean, friendly and cared about his job. I followed him around and enjoyed him describing how a house can be more efficient by changing even the smallest things, like the light bulbs. At the end, we sat at the table and went over everything. There was no catch. No cost. I am happy.

Mallard Energy Systems came to my house and showed me every step of the process toward getting my home more efficient. Jeff was very friendly and personable. I was surprised how thorough he was. He even went up in my attic to check the insulation.
