My Review by angelikah via Citysearch on 8/9/2013

Total RIPOFF! I had a plumber come out because of water heater that needed to have some leaks fixed after we made it a DIY project. The quote started at $160 but then after replacing five copper pieces, the total came out to $245. I was…

Stay away - use anyone else by Marcie W via Insider Pages on 5/12/2012

These people are dishonest and will cheat you. Do not do business with them under any circumstances. I hope that this review saves someone else from being cheated by these bad people.

Absolutely DO NOT USE by marathonman1 via Citysearch on 5/11/2012

The positive reviews here must be fakes written by the company. Please check other review sites as well prior to using this company for any work. They are dishonest and will cheat you, and do poor quality work and are rude. Deal with them…

Breathing Clean by Jackie S via Insider Pages on 10/28/2011

Black Diamond has done several jobs at my home. They are always there when I need them. It's hard to find a company you can rely on to get the job done the first time, Black Diamond is that company. Recently I had my ducts cleaned by them…

Loyal Customer by Maryanne b via Insider Pages on 10/27/2011

Black Diamond truly says what they are going to do and does it every time. I have been a satisfied Diamond Club member for over 8 years at my last home and now at my current home and rental property. They always show up the same day I…

Top of the Line Service by Claire B via Insider Pages on 3/10/2011

I called Black Diamond to install a ceiling fan in my bedroom. The girl on the phone told me she could have someone there that day! I have never heard of that before. When Ricky came to my house, he immediately put on shoe covers and gave…

Brightened my day... by ctbrok via Citysearch on 3/9/2011

It's rare that a company says what they are going to do and actually does it. Black Diamond came out to my house the same day I called them. Unheard of as far as I am concerned. They were neat, clean, and very helpful. The electrician knew…

Can't ask for anything more!! by Gui A via Insider Pages on 3/9/2011

Our furnace had always been an area of concern since we moved into this house. We had it checked out a couple of times by other companies within the Crystal Lake area. They all just came in and spent no more than 15 minutes down by the…

Customer Service by cvogert via Citysearch on 11/17/2010

I called Black Diamond to have someone come out to figure out what this knocking sound was after the toilet flushed & the faucets were turned off. It had been happening for awhile and it seemed like it was getting worse. I did some…

The Best by Joe M via Insider Pages on 7/9/2010

I had furnace, AC and water heater replaced. The team was efficient, extremely polite and beter than competition (based on 3 quotes). I could not be more pleased with the experience.

Overcharged, mislead, rude owners by C G via Insider Pages on 2/15/2010

We were completely mislead and charged a total of $395 for an ignitor on a standard water heater nothing special. Not on call hours either. Do you know a new water heater is $450? I could have gotten a new warranty. I called just to…
