Hands down, has to be one of the best companies I have ever used! My wife and I are expecting our first child so we needed an AC unit in our house ASAP. After shopping around and getting treated terrible by other AC companies we came across 5 Diamond. Carlos and Nick were friendly and understanding to our situation, they personally came out to do the pre-inspections. After deciding what would work with our budget , they were prompt to start the job. During the instillation they showed up on time, were polite, and even brought us breakfast. Everyday they did a walk thru going over, with complete detail, what was happening so we never had a question to what was going on. The units installed were put to the test this week with a heat wave and temps in the 100s. We were ice cool and so thankful we decided to get the mini split system installed , and so fast !!!Like I said before, I have never worked with a better company and highly recommend them for the job. Not only did they walk away with a outstanding working system and flawless craftsmanship, but with my friendship.
