We strongly encourage you to provide a review of our company performance when we have served you. Potential future customers like to know what others are saying about our company. Normally we just post reviews on our website, but thought this one good enough that it was worth repeating here:

“I just wanted to let you know directly too how much I appreciate everyone’s good work there. The HVAC unit has been humming along flawlessly and both I, and my wife, are grateful for the high quality of workmanship and truly working to think about us as customers with money saving advice from Brian. I had contacted several other companies before yours to see about having the repair work done. There was one company that was looking promising, with a low diagnostic cost, but they then made other statements on the phone that clearly were signs the costs were going to be significant. In one case concluding on the phone, without even seeing the unit, that the compressor would likely need to be replaced. I am a software engineer as well as pilot and professional photographer, so I understand about logic, diagnosis, troubleshooting, and applying fixes. I knew a jump like that by the other company was not even reasonable, and a precursor of a setup to replace the unit. I can’t guarantee that is what they were going to do, but it didn’t give me a sense of ease or professionalism. I’m really glad I went with your company. The professionalism, and honesty, are highly valued, and I’m certain saved me money. I wanted to express this more completely than the review engine allows. Please do feel free to pass this along to the team there. It is wonderful to find a great company with such quality staff”. Bob G.
