He thoroughly answered my questions and provided me with a fair quote. On the day of installation, Derek and his team were like a well-oiled machine; they worked efficiently and kept the area clean during the process. When the installation was completed, the system was tested and I was very satisfied with results. Derek took the time to explain the system so that I understood how to operate it. I highly recommend them!

The owner was very helpful and patient with me considering I had a lot of questions bc it's a big purchase. The crew came out yesterday and today, as scheduled.

So far my husband and I are very happy with our experience with this company. Thank you!

I hired Aaron, guided by the multiple positive reviews he had -- but sadly, my experience turned…read moreinto a nightmare. I paid $1,950, plus an additional $100 for the initial diagnosis, to have the compressor in my HVAC system replaced. He installed it -- but it failed within just a few days. When I reached out, he told me the compressor was under warranty, but not the labor, meaning I'd have to pay over $1,000 again to fix a problem caused by his own installation. He also said he didn't know what caused the failure and couldn't guarantee it wouldn't happen again -- which didn't inspire confidence. Out of desperation, and not wanting to be caught in another heatwave, I hired a second technician to inspect the system. That inspection revealed multiple serious issues: The attic unit was never accessed or flushed -- a required step after a burnout The filter-drier was reused and visibly rusted, which is a recipe for failure The capacitor used was one I had installed myself, not a new one The compressor was not properly matched to my 2.0-ton system Worse, the second inspection confirmed that, due to the compressor burning out a second time and the system not being properly flushed the first time, there was now twice the level of acid contamination in the system. At that point, saving the system was no longer an option -- the only solution was a full replacement. Aaron clearly knew this, and that's why he kept saying he couldn't guarantee it would work. Yet instead of taking responsibility, he kept making me lose time and money -- while offering to reinstall the same compressor without fixing the root issue or standing behind the work. After I tried to resolve things respectfully, he refunded me only $650, charging me for a failed installation and a compressor that stopped working due to his own negligence. I asked for a full refund, but he refused -- saying his offer to reinstall the compressor (with no labor warranty) was enough. But I had already lost confidence. I didn't pay for guesses -- I paid for a working AC system. From my personal experience, I strongly recommend getting everything in writing and making sure the contractor stands behind both parts and labor. It's not just about being nice -- it's about doing the job right the first time. Your family's comfort, safety, and time matter.

I scheduled mine and the guy told me I needed a new central AC system. Quoted me $13k. Wow. My AC compressor randomly stopped working after he left and the company said I didn't have enough r22 to power it. Sounded shady bc it was running when he was here. A month later, I decide to have a different HVAC company come take a look. They said my wires were disconnected outside and the ground wire was disconnected and it reset the breaker. The tech was obviously trying to get a commission off a new ac from me. I had to buy window units during that time just to get by in this heat. Wasted money that I don't have! SMH shame on SJ KOWALSKI!

He did a great job of troubleshooting and explaining all aspects of the trouble we were encountering. The problem was a bad end switch on upstairs zone valve.

Nate is definite asset to an already outstanding organization.
