Climate Diagnostics, LLC

Brian was great he was able to get me in on a Sunday and was very professional. He quickly diagnosed the problem and then corrected it I could not be happier

if you are looking to install a ductless mini-split system, I highly recommend Brian Lorek, Climate Diagnostics, 716-602-6337. He just installed a two compressor, 5 head system in my house in Williamsville. He is knowledgeable, patient, competent and explains everything. He is both the estimator and the installer so the guy you're talking with upfront is the guy doing the installation. And price-wise, he is very reasonable. The installation was complex and he did a fabulous job. He gets a 10/10 in my book.

Did a great job installing my furnace and AC unit. Very flexible and professional!

Excellent service, great price, Brian was punctual and delivered on everything he promised.

I had a few estimates from some well known companies to install a new furnace & Air Conditioner for my house. Brian's estimate was a lot lower for a similar system. He gave us all the AC and furnace brochures so we could actually see what parts we will get. He explained in details all (3) different options, their costs vs features to help us decide what we really needed. 3 days after I approved the contract, Brian showed up early in the morning with all the parts. He got the old furnace out, the new one installed and working by 5PM. The AC replacement was completed the next day, even though we won't need to use the AC anytime soon. He then called us everyday for the next few days to make sure our system is working properly, which it is. All in all, it was a pleasure to do business with Brian. no hard pressure sell, just professional and good work ethics. Will recommend him to anyone.
