Editorial Review
Our Take on Climate Diagnostics LLC
Every review on Climate Diagnostics' page names the same person, Brian Lorek, which is the clearest possible signal that the owner is still doing the actual work. The mini-split and ductless focus, backed by RUUD and Mitsubishi authorized-dealer status, makes this a strong pick for that specific kind of job.
Best for: mini-split installation and repair from a single, hands-on Buffalo technician
What We Like

- Owner Brian Lorek personally handles jobs and reviews name him directly and consistently
- Authorized RUUD and Mitsubishi dealer, also services Trane, Carrier, Goodman and Bryant equipment
- One-year labor warranty on every installation, on top of manufacturer coverage
- Reviews describe direct manufacturer follow-up on a warranty claim rather than leaving the customer to handle it
Things to Consider

- Chau Nguyen5.0Brian is awesome! He is the definition of a small business owner who puts his clients first. I've had full HVAC and ductless mini split installed and they have been flawless. Great communication and always responsive.September 2026Google
- Anthony M5.0Brian treats his customers like family and that’s why I decided to work with him. Brian installed a new mini split system for me and in a world of HVAC companies that are trying to take advantage of you, Brian is not like that. He quoted me a few thousand dollars less than the next closest company for a very similar install and got it done for me the next week after initially contacting him. Brian handles all of the warranty and rebates as well, and also offers a one year warranty through his company for peace of mind. Thank you Brian!September 2026Google
- H Laa5.0We've used Bryan's services twice so far and in emergency situations where the heat went off during the cold period of the year, he was very responsive and helped us fix the problem the same day in both occasions. He is very knowledgable on all types of furnaces, explains what the diagnostic is and fixes it. His prices are also very reasonable and we've now made him our go to guy for all things HVAC and water boiler! We strongly recommend him.August 2026Google
- Mike Boardman5.0Fast, efficient, and fair! In a world where finding honest and fair work seems impossible, Brian shines! Not only is he fair on pricing (also a rarity in these times) but he was insanely fast as well as very clean. Most times contractors leave a huge mess behind but he was very mindful and respectful of my space to the point that I forgot he was ever even here. That alone is worth 5 stars!August 2026Google
- LouAnn Lindemuth5.0Thanks to Brian and his son, my air conditioner is now running great!! He explained what was wrong and got the fan motor that was needed. The cost was good and I will hire him again when needed. Thanks BrianJune 2026Google
- Melissa Shaw5.0Brian and his son are very professional and knowledgeable! They have a quick response time and explained everything as they went! Highly recommend them for all HVAC needs!June 2026Google

iAbout service coverage
Coverage is as the business describes it, cross-checked against where its recent documented work is. A company will often travel beyond the areas listed here for a large job and decline a small one at the same distance, so confirm your address before scheduling.
About Climate Diagnostics LLC
Climate Diagnostics LLC is a small operation founded and run by Brian Lorek from a Zittel Street base on Buffalo's east side, roughly 15 years in business according to the company's own site. Every review on the company's Google profile names Brian directly, a pattern only possible at this scale, and it points to a business where the person quoting the job is the same person doing the work.
David Bozek's review describes two mini-split installations with a reasonable quote and a commitment from Brian to return and adjust the system until the customer was fully satisfied. H Laa's review describes two separate winter emergencies where the heat went out during the coldest stretch of the year, with Brian responding and fixing the problem the same day both times, alongside a description of him as knowledgeable across many furnace types. LouAnn Lindemuth credited Brian and his son with diagnosing and fixing a broken fan motor at a fair cost. Jessica Park-Brooks's review describes a heat pump mini-split installation where a part malfunctioned after the fact, and Brian worked directly with the manufacturer to resolve it rather than leaving the customer to handle the warranty claim alone.
Climate Diagnostics works as an authorized RUUD and Mitsubishi dealer, and also services York, Carrier, Ductless Aire, Trane, Aprilaire, Goodman and Bryant equipment. The company publishes a one-year labor warranty on every installation on top of the manufacturer's own warranty, and advertises 24/7 service, though at this size that likely means Brian personally taking after-hours calls rather than a dispatch team.
Being a single-technician operation is both the appeal and the limit here. Reviewers consistently describe a level of personal follow-through, including working directly with manufacturers on warranty claims, that is harder to get from a larger company, but it also means capacity is naturally limited compared with a multi-crew operator.
Who this suits: a homeowner who wants a single, hands-on technician for a mini-split or ductless system and values one point of contact through the entire job, including any warranty follow-up. Who might look elsewhere: anyone who needs a larger crew for scheduling flexibility on a big multi-unit job.
Before booking, ask about current scheduling lead time given the single-technician model, and confirm what the one-year labor warranty specifically covers.

Climate Diagnostics LLC FAQs
Is Climate Diagnostics an authorized dealer for any HVAC brands?
Yes, the company is an authorized RUUD and Mitsubishi dealer, and also services York, Carrier, Ductless Aire, Trane, Aprilaire, Goodman and Bryant equipment. Ask which authorized-dealer status applies to the brand you're considering, since it can affect warranty registration.
Is Climate Diagnostics available for emergencies?
The company advertises 24/7 service, though as a single-technician operation this likely means owner Brian Lorek personally taking after-hours calls rather than a dispatch team. Confirm current availability directly, especially during a winter cold snap.
What warranty does Climate Diagnostics offer on installations?
The company publishes a one-year labor warranty on every installation, on top of the manufacturer's own warranty. Ask what specifically the labor warranty covers and how a warranty claim gets filed if a part fails.
Is Climate Diagnostics LLC licensed and insured?
We checked 0 of 2 credentials against the issuing authority. Verified items carry the date we checked; reported items are what the business told us and we could not independently confirm.
What areas does Climate Diagnostics LLC serve?
Buffalo. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does Climate Diagnostics LLC offer emergency service?
Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.
What warranty do they offer?
One-year labor warranty on every installation, plus manufacturer's warranty. There are usually two warranties on a job: the manufacturer covers materials, the contractor covers workmanship. Get both in writing and check whether the workmanship coverage transfers if you sell.
