Power outage




As per usual, the response was quick and the service succinct. Although the problem could not be resolved by Black Diamond, their serviceman was helpful in identifying the cause of the problem and directing me to ComEd.

Friendly, clear spoken repairman




Furnace was acting up. Frigid morning. Repairman arrived same day. Needed new control board. Gave me a discount since it was his second call on our furnace. Working great now!

Great service and response.




At around noon or so on Super Bowl Sunday we discovered our sewer line was clogged, we called several companies to no avail then we call Black Diamond the phone was answered right away and they said James would be there within the hour. James showed up about 35 minutes later and proceeded to rod on the sewer pipe with the root cutters and got the drain unclogged just before our 20 or so guests arrived. Thank you very much.

Great Service on a Late Night!




Service tech did a great job & we had heat a few minutes after his getting to our home. Thank you!


Ask for the deduction




Black Diamond says they will deduct the cost of the initial inspection visit from your total repair cost if you select them to do the repair. Repairman did not include this deduction in my total repair cost. I had to ask for it. Is it company policy or not? Was it an oversight or not?


Response from Black Diamond:

Debbie, thanks for reaching out. It is company policy that we waive the diagnostic trip fee once you accept the repair. Yes, it was an oversight that the technician forgot to do this and you had to remind him. We're sorry for the inconvenience, but we have verified that your diagnostic trip fee was removed from your invoice. Thanks again for letting us know so that we can review the procedures with the tech.

amazing service





Job well done




Andy was very pleasant and did a wonderful job cleaning our 1 furnace and assessing the life-status of the "dinosaur furnace". Turns out the dinosaur needed to go!!! He was super awesome contacting the office and scheduling a salesperson to come talk to us about furnaces. Andy did a great job!!


Great job




Rudy and Brady did a wonderful job installing our new furnace and 2 humidifiers. (We have 2 furnaces). They were clean and considerate and left the work site very clean.


Great job




The guys did a wonderful job removing our old "dinosaur furnace", and installing a nice new shiny energy efficient furnace. They also installed 2 humidifiers (we have 2 furnaces) and did the prep work for our new air conditioner. (which will be installed in spring when it's not below zero outside) They were kind and considerate and left the work area very clean. Brady took the extra time to help me get our digital WiFi thermostat registered and explained the whole thing to me. Excellent experience.
