I highly recommend 4 Corners Heating and Cooling. The two brothers, Chris and Szymon, are not only skilled professionals but also genuinely good guys. They are committed to providing excellent customer service and ensure that your HVAC needs are met with care and expertise. Whether it's routine maintenance or emergency repairs, you can trust them to get the job done right.

I would recommend this HVAC company to everyone possible! They did an awesome job installing our humidifier. I called them again when my furnace broke and they were able to come out the same day! They were knowledgeable, explained everything clearly, and got my heat back on in no time. With the cold weather we've had and having a toddler at home, I was beyond grateful for their hard work and responsiveness. I have an awesome experience with Kris & Simon every time! Thank you, thank you!!

From start to finish, 4 Corners Heating & Cooling was professional and knowledgeable about which furnace would be the best replacement for our home. Our old furnace gave out with no warning, which left our house cold and uncomfortable. After a call to them, they promptly came to our home to assess our needs, sent over a reasonable proposal within 12 hours and installed our new furnace with the utmost professionalism. We will recommend Kris and Simon to all of our homeowner friends, and will not hesitate to call them in the future with any HVAC needs. I highly recommend them.

Kris came out to fix my heating and cooling system, and he was awesome. I don’t know much about this stuff, but he took the time to explain what was going on in a way I could actually understand. He got it fixed really quickly and was super friendly the whole time. Definitely gave me a peace of mind. Highly recommend them if you need reliable HVAC service that doesn’t make you feel clueless!

Kris came out initially to provide a quote for installing mini split in my garage. His demeanor was extremely professional and his quote was extremely reasonable compared with others. On install day, he came with another helper and together they installed my mini split professionally. He did not rush the job and also made sure everything was cleaned up properly. Thanks Kris!

Kris from 4 Corners Heating and Cooling came through big time. He fixed the furnace on one of my properties quickly and professionally, no runaround.

I thoroughly enjoyed my experience with Kris and his professionalism in carrying out the repair for my unit. He quickly diagnosed the issue, started and completed the repair the same day, but also discussed ways to avoid the issue and even provided suggestions on how I can save money to prevent further repairs!! He was patient with me to answer any question that I had, and even walked through the various parts of my unit, what they did, and how to maintain upkeep for my unit to ensure I felt knowledgeable as a homeowner. I would recommend his services to anyone looking to support a local business! The BEST experience I've ever had with HVAC repairs.

Great company!

We hired 4 Corners Heating & Cooling to perform a check/cleaning of our AC unit of our “new to us” house where we were uncertain of the prior maintenance of the unit. Krzysztof was quick to respond to my inquiry and we were able to schedule the work in less than 2 days! During the appointment the team was quick and communicative. They shared pictures of their findings (which included a mouse — ick!) and offered helpful suggestions about our unit and a possible issue with the capacitor. There was no sales pressure which I super appreciated, just knowledgeable information and recommendations. The results speak for themself. Will absolutely be hiring them again with any future HVAC needs!

I want to personally thank Chris and Simon from 4 Corners Heating & Cooling for their incredible professionalism, knowledge, and quality of work. These guys are truly experts at their craft.
I had several other companies come out over the past year to repair my furnace because it wasn’t heating my home correctly. I spent a LOT of money with no results. My house kept getting cold at night—so cold we were freezing inside—and the problem never went away.
Chris and Simon came out and fixed the issue in less than an hour. Since then, my heating system has been working perfectly! Their price was reasonable, and they explained everything they were doing step-by-step. They even provided a detailed invoice for the work completed—something I never received from the other companies.
I’ve been trying to get this problem fixed for so long, and these guys solved it quickly and professionally. They are truly top-notch and extremely respectful. From now on, I will only use 4 Corners Heating & Cooling for any heating or cooling needs.

I had a great experience with 4 Corners Heating & Cooling. Kris came by to service my furnace and AC. He was very knowledgeable and professional. He took the time to explain what was going on and what to keep an eye on, without trying to sell me anything I didn’t need. I really appreciated the honest approach and helpful information. I’d definitely recommend them and would call them again in the future.

I hired 4 Corners to replace my aging furnace and AC. After several quotes, I decided to go with this local team because they actually perform the work themselves - unlike the pushy salespeople from the bigger companies. I am incredibly happy with that decision!

​Chris and Simon were professional, experienced, and friendly. They got the new system installed quickly, and the installation itself was super clean. They took the time to explain everything, test the system, and walk me through all the features. I highly recommend these guys if you want honest, high-quality work!
