Brian Lorek was very understanding and explained what needed to be done throughout the whole process. Very good experience. Reasonably priced compared to other companies we called. So glad to finally have our AC running the way it should be again! Would highly recommend.

Brian installed mini split AC units for our upstairs bedrooms. Everything about the job was 5 stars. He always responded in a timely manner, walked us through every part of the job and completed it in the time frame given. We could not be happier with the final product.

Mark Demmin

Brian is definitely one of the most accommodating contractors my husband and I have done business with. He goes above and beyond for his customers. Provided a very detailed estimate for an install of a new furnace and air conditioner. We took advantage of the discount for having both installed at the same time. An added bonus is he fills out all the warranty paper work and emails the completed contracts back to you. We would definitely recommend Brian for all your HVAC needs.

Richard McCarthy

I was fortunate to meet Brian from Climate Diagnostics. He installed a Mitsubishi Hyper Heat unit in our upstairs home, and we couldn't be happier. He was straight forward and explained the process of the installation step by step. Brian is a down-to-earth person with the mechanical expertise to get the job done affordably and sensibly. He is a top-class technician whom I would highly recommend for your heating and cooling needs, and we are 100% happy with the results.

Paula Rudick

Brian did an amazing job! He advised me on the best options and got what I need done promptly! Even stayed to make sure everything was working right. He cares about his customers and is very fair with pricing!

Kourtney Mele

As a new homeowner, my recent experiences with contractors have been nothing but frustrating, but Brian has been the exception. We hired him to install an AC unit, and our experience was 100% positive, easily the best of the 'big jobs' so far. There actually came a point (and it was very early on) when I thought "Wow, I didn't think people like this existed anymore": i.e., people who love their work, believe in it, and are proud of it and eager to stand by it.

Kevin Kane
