Fifty years out of one shop, and the owner still prices the job.

The person pricing your job
Owns the company.
“I've been very happy with Douglas Mechanical since their owner, not just a salesman, came to check my system and give me their estimate. I got 5 estimates and Douglas was right on point with their pricing compared to the others.”
No salesmen. No commission.
Douglas Mechanical does not employ salesmen and does not work on a commission basis, so the price is not padded to pay a salesman. In the company’s own words: “You never have to worry about any hidden costs or surprises once your HVAC project is complete.”
Jared gets involved in the sale.
Jared is the owner, and customers name him in their reviews as the owner who came out for the estimate and was involved in the sale and the follow up.
“Jared, the owner of the company, was involved in the sale and follow up. He and his team were extremely knowledgeable and offered multiple options that worked within our budget”
What the company says it is for.
