Heating & Air Conditioning / HVAC near Monument

“Great, thorough service! My heating oil furnace is running smooth and more quiet than ever“

“Don’t think twice about using this company. They did a terrific job with the install and provided everything at a very good price (less than competitors and that’s with added soffit vents and larger fan). Super satisfied!“

“The technician was friendly and thorough but he was several hours late for my appointment. I had to call the company to report he had not shown up. He was on an emergency job somewhere else. I have had issues in the past with no one answering the phone. Their work has always been good.“

“Diamondship Mechanical is the best! Last winter, my furnace needed to be serviced and an incredible technician showed up the same day. Expert knowledge, Highest Integrity & a fair price. Amazing!“

“Terry showed up on time...was very polite & explained everything that he inspected. We were selling our home so we needed our invoice detailed out a little more to provide to the new buyer. He gave an exceptional write-up detailing what was done/inspected. Yes, very reliable and professional.“
