About E&A Mechanical

Why Choose E&A Mechanical as Your HVAC Company

Four things you can check on us before you call anybody.

The same four people, every visit. Mike, the owner, is still on the trucks. Chad, James and Charlie are the other three technicians, and Rachael runs the schedule. Nobody hands your job to a subcontractor you have never met.
The total is the quote. A written estimate comes before the work, every time. One customer put it this way on Google: “The total was spot on from quote.”
Options, with the trade-offs. Where there is more than one way to fix it you get the choices side by side, with the pros and cons of each, and the decision stays yours.
Tested and explained before we go. The finished system gets run and checked, then you get walked through how it works and what it needs.

Testimonials

What Your Neighbors Are Saying About Us

E&A Mechanical is an excellent company. We received an estimate from Apple plumbing which we've used before for bathroom work & got back a very high quote. So through family we contacted E&A Mechanical. Our experience with them from start to finish was great.

Mike and his team are awesome, I highly recommend them. It was easy to schedule an appointment and Mike was very patient, responsive and kind to communicate with. I had a new heat pump with back up oil furnace installed.
