Holtorf – Lake in the Hills, IL

I was very impressed with the staff and Black Diamond. Had several issues with a furnace install and they stuck with it til all issues resolved. Kyle, Alex, Oscar, and all the rest I dealt with were very pleasant and patient and took care of any and all issues. They were neat, and cleaned up after the jobs were done. Will for sure use them again. CLH

Estelle – Lake in the Hills, IL

Pricing was ridiculous but was in a time crunch so opted to pay enormous price for the work. Will not do this again.

Brett – Lake in the Hills, IL

Great customer service from the first phone call. I have a business in CL and hear your commercials on Star 105. Everything you advertise is spot on!

Joann – Lake in the Hills, IL

We found our hot water heater leaking on a Sunday. We called for help at 11:30 am and the new replacement was up and running by 3:30 pm. Our technician, Josh was extremely helpful and friendly.

GEORGE – Lake in the Hills, IL

Luis did a great job and was very helpful. We appreciate his ability to help us with his professional knowledge. That is why we always call Black Diamond for our plumbing, heating and air conditioning needs. Thank you, Luis.

John – Lake in the Hills, IL

Tim and Jim were the best… electrician and plumber… great work…explained quotes thoroughly… jobs well done… very satisfied

Oscar – Lake in the Hills, IL

There is a trip fee charged. Trip fee changes if it is after hours or weekend. They wont make it clear if the whole trip fee is waived if you decide to do the service. Be careful. Fee is split in 2. First 79$ + 95$ (after hours/wknd). Only first fee is waived. They won’t be clear. You would assume that the whole “trip fee” is waived regardless if is after-hours, but nope.

Response from Black Diamond:
Hi Oscar. We’re sorry you’re still confused about this. We reviewed your call recordings several times to make sure that we were as clear as possible with you on the phone, and we feel that we were. We’ll review this again with our scheduling department, but we absolutely did not intend to confuse you and we think we did a pretty good job of explaining it. We’re sorry you are disappointed to pay the $95 fee for having us come out afterhours.
