He and his man shoveled all the walkways and the driveway so my wife could get her car out in the morning. They did this because they wanted to make sure the repair would work, and after the installation of the part, there was a certain amount of time the system needed to reboot. I repeatedly tried to pay him for all the extra attention and he refused. This is a true pay it forward company. There are few of these type of businesses these days. He limits his client base because it's not about the money it's more of a passion for this guy. I wish you nothing but more success.

My call was answered by Cheryl (I believe that was her name...if not I apologize in advance). She was so courteous and helpful. Instead of taking my name and telling me someone will call me back.

Once we figured out that the issue will need professional help she got me on the calendar as soon as possible. I was scheduled with Lou A. He was super communicative prior to the appointment. Once here, he quickly diagnosed that the problem was the capacitor and got the ac working in no time. Despite having a jammed schedule he did not make me feel rushed and answered all my questions. Their fees were fair and not one of those big companies where they will nickel and dime you for every little thing they do. I've used several hvac companies in the past and this has been the best experience thus far. We will look to use these guys for future issues.

He advised me that he needed to install emergency disconnect which he didn't tell me and he wanted additional $400. He told me its the code requirement. I agreed. He replaced the electrical panel and installed the emergency disconnect. He gave the Certificate of Insurance for Mr. Ray Mechanical LLC. However, I found out the electric permit was issued to a different company. He work failed inspection because the emergency disconnect was not needed. He misunderstood the code. The town's inspector had to write down the code for him. Then, he had to add main breaker to the panel. I refused to pay the $400 which was for the unnecessary emergency disconnect. I had to spend two more half days to facilitate the revision of the panel work and coordinate town's re-inspection. Ramon, the owner of Mr. Ray Mechanical insists he has electrical license. He does not. Anyone wants to hire him to do electrical or any home improvement project should ask him to show his license.

I am a consulting engineer and retired hvac engineer. I have been in the business for over 40 years. Recently I took on an account to which they were at their wits end regarding their comfort issues. I was introduced to Dave though a friend, and hired his company to investigate the building. After several days of taking readings and traversing ductwork, He was able to make some simple adjustments, bringing the building back to a reasonable degree of comfort. Along the way making suggestions and implementing some of these resulted in some very happy tenants as well as the owners. Bottom line, I was extremely happy with using Keiser mechanical, and will most likely use no one else. Five stars .
