Christine - Woodstock, IL
From making the call for service to questions about whether we had anything else we needed done while he was there our experience was outstanding. And not for the usual big name service provider prices which was awesome. We will definitely keep using Black Diamond!!

First HVAC Impression !!!
John - Woodstock, IL
In search of a new HVAC company, after the one we had used for years was sold & doubled their prices; decided on working with a company that has been in the area a long time and developed an excellent reputation. First 'annual service plan' visit lived up to our expectations. Friendly, knowledgeable service tech....looks like we'll stay warm this winter.

Dj - Woodstock, IL
I had a big repair job at my rental property. With a prior estimate of 12k to do the work from a competitor, I decided on a second opinion. I'm so glad I found Black Diamond. They did the work at half the cost. The crew they sent was wonderful. It was enjoyable to spend two days with them at my home digging up my front yard and basement. Good hard workers with congenial personalities. I would recommend this company without reservation.
Kathy - Woodstock, IL
Josh provided the best service. Professional. Friendly. Explained everything about our new hot water heater. I could not be happier with the service received. Called this morning. Thanksgiving week. New hit water heater hooked up and ready to go same day. Josh won Black Diamond a new customer for life.
Excelent service, job well done, Keith Hengler was friendly.
Lou - Woodstock, IL
I was very pleased with the work that was done by Keith Hengler. I called Black Diamond because my furnace blower was not working properly. The blower/fan would start up and stop after a short period of time. Keith fixed that problem and did an great job of cleaning the interior and exterior of the furnace. His estimate was close to the actual price that I paid which was very satisfactory. I would recommend him to others.
Friendly Professional Service

Juan explained everything he did, making it easy to understand. He made sure to wear coverings over his shoes so not to soil the floor/carpet. He ws good humored, friendly and represented Black Diamond well.
