Smooth Installation

PEGGY from Woodstock, IL

I had a new furnace install by Ryan and Tom. They worked very well as a team, and they were very careful not to inconvenience me. The installation of the furnace was efficient and went smoothly. Both were very polite, and overall it was a positive experience.

Very pleased with service.

Deb from Woodstock, IL

Very professional. Explained problem, provided suggestions for preventing future problems with water heater.

Black Diamond is the very best.

JIM from Woodstock, IL

We had a issue with our existing A/C unit. From the first technition who found our problem and explained our options, then Mike in sales who went over the cost of all our options, and to the crew of Dave, and Tom who installed our new equipment... It was a pleasure to have the Black Diamond team take care of us. If you want a job done right the first time Black Diamond is you answer. Highly recommend them, and we joined the "Crystal Club" Because we will use them for all our plumbing, Heating, A/C, and electrical needs in the future! Thank you all!

A routine inspection turned into a larger job when Jason found the water heater exhaust pipe had broken off inside the attic. He replaced the pipe, including getting out up on the roof in cold, wet weather to make sure it was complete and done right - we are so grateful!

Polite and professional service. -Very informative.
