GREAT PEOPLE AND NO HIGH PRESSURE SELLING!! VERY PROFESSIONAL SERVICE

Had whole system, furnace and A/C, replaced. Kyle came to the house and inspected the current system. He was extremely knowledgeable and no pressure to upset added options or more expensive units. He explained in detail what we would be gaining from each option we chose and the difference in more expensive units they offered. They were able to install within 48 hrs and the job was done fast, clean and professionally. They took the extra time to make sure everything was 100% accurate and complete. I have used Black Diamond for the past 16 yrs and every time I have the same experience which is second to none. They could have tried to up sell me or over charge me in the past and every tech has been honest, and professional. Would highly recommend them to anyone in need of their service.

Sump pump replacement

Job well done problem solved. Glad I caught it before it got really bad & fortunately basement isn't finished yet. Dave did a great Job replacing the sump pump, knowledgeable and it was less better than you found it. A little expensive but being up all night I had nothing left & had to deligate it.

Quick response time

I can count on this company to give me the quickest response time for their service technician to arrive at my home. This is very important when it comes to my furnace or air conditioner. I rarely give 5 stars to any review as that leave no room for improvement. I definitely recommend Black Diamond.
