Great Service

Dale from Huntley, IL

The technitions arrived on time, went right to work without wasting any time and finished the job quickly. They left our place with no mess -almost cleaner than when they arrived and the job was done perfectly.

Technician was very good and considerate.

Fran from Huntley, IL

We called for a technical in the middle of the night and he came out and helped us out a lot which gave us peace of mind so we could sleep without worry. He did a great job and cleaned up afterwards which was a big help especially for an older couple.

Patient..answered questions,solved the problem.

Electrical Problem

George from Huntley, IL

Called BD about 10:00 AM, got an appointment for same day at 2:00 PM Daniel knew exactly what the problem was and he fixed it in about 10 minutes. Well worth the price as I am scared of electricity! Glad to have the pro on the job.

Great service as always!!

Professionals with quality service

Orion from Huntley, IL

Recently had two experiences with Black Diamond. Michael M. serviced our dead A/C and Keo V. came the following week to do the annual checkup on the AC/Furnace and Hot Water heater. Both gentlemen were ON TIME, efficient, informative and polite. I am not accustomed to service people arriving ON TIME...that was refreshing!

Usual excellent service

David from Huntley, IL

Again you have come through, arriving within a couple of hours after my contact with you. There is an axiom in business that never fails: "What every customer wants is the best service and the best product for the cheapest price. The reality is that you can only have 2 of the 3." I choose Black Diamond every time because you deliver the first two every time!
