I highly recommend AB Diamond Heating & Cooling. I had an emergency situation during the summer with my 2-month-old baby when our AC suddenly stopped working. I was extremely nervous because of the heat and my baby’s comfort and safety. I called Aziz, and he exceeded my expectations. He arrived on time, quickly diagnosed the issue, and found that the thermostat was not sending a signal. He went into his Van , and got me a replacement brand new thermostat. He also discovered that my compressor was low on refrigerant and fixed everything promptly. Because of that great experience, I called them again during the winter when my vents started blowing cold air. Once again, Aziz came as expected, quickly diagnosed the issue (a gas solenoid), and returned the next day with the part. He installed it, and everything has been working perfectly since then. During the visit, he also noticed that my heating unit had a humidifier installed but not properly, something I didn’t even know about since I had purchased my house the previous summer. He fixed the humidifier, replaced the filter, and installed a new filter cover as well. After these experiences, I decided to hire them for routine inspections, and Aziz is now my first point of contact for any HVAC needs. He is extremely knowledgeable, has many years of experience, and delivers high-quality work. He is honest, targets the real problem, and doesn’t push unnecessary parts or repairs, which saves you money. Aziz is always on time, offers very fair pricing, and provides excellent customer service. What you spend with this company is absolutely worth the quality of work you receive. I highly recommend AB Diamond Heating & Cooling. Keep up the great work!

I highly recommend Aziz for any HVAC needs! I called him last August when our unit stopped cooling, and he showed up with a great attitude and a genuine desire to help my family get comfortable again as quickly as possible. He was able to troubleshoot the issue immediately, identified a bad capacitor, and had the replacement part ready in his van. He handled the repair safely and efficiently, and we had cold air running again in no time. Great service and a true professional!

highly recommend AB Diamond Heating and Cooling LLC. He was incredibly kind and professional throughout the entire visit. After checking my system, he went above and beyond by giving me expert advice on how to maintain it so it keeps running smoothly for years to come. It’s rare to find someone who takes the time to truly help the customer like that.

The initial installation and work was very good, however follow-up on a problem encountered has been extremely poor.  Diamond Contracting promised that any problems that cropped up would be taken care of quickly.  The downspout on the front porch was built into one of the posts.  We noticed in October 2014 that water was leaking from the bottom of the post.  Phone calls were made to Diamond Contracting and there was no response.  We had also requested the power wash be performed on the house which was to occur one year after installation.  An email was sent to the company that was not answered until January 2015.  The owner Wes McIntire stated he would be by the house the next day to look at the problem.  We did not receive any follow-up and in February, 2015 another email was sent to asking if the problem had been looked at.  Wes McIntire had not been by the house.  Following another phone call, an appointment was set up for March 14 to look at the post and do the power wash on the house. Mr. McIntire stated the downspout was leaking and the post needed to be rebuilt.  He promised to complete the work shortly.  To date, the work has still not been completed.  The joints on the post are separating due to water damage. <br />  We believed the company when they said they would take care of any issues that arose however our experience has been to the contrary. <br /> <br />

The owner provided very clear documentation outlining every aspect of the job and clearly defining what was included and the timeframe for completion. Since we started late in the fall heading into winter, the full completion took a little longer due to weather, but the job was 95% complete within the time we expected. Their project manager and foreman were clear in communicating progress and next steps and they always showed up when they said they would be working. They were very thorough in documenting the punchlist of items that needed to be completed before the job was finished. In fact, we went through the punchlist twice to make sure it was all completed to our satisfaction. Diamond truly cares about these on-line reviews becuase they did everything they could to make sure we were happy with the outcome. I could not have expected a better experience. <br />

The starting point on this job was making the selection of the contractor to replace all of the siding on our house. We selected Diamond Contracting. This was a huge project and for the most part all went well. It took about three weeks to complete the work. The house looks great and we are very happy with the overall work. We did have a couple of issues along the way but once the problem was brought to the attention of Wes and Cecelia it was taken care of. I would recommend using Diamond Contracting to anyone. As with all contractors, we reviewed the work done each day for quality. <br /> The people at Diamond Contracting were very helpful in selection the color of the siding on our home and made recommendations that I think improved the look of our home. They did a great job. <br />
