He didn't have the exact part we needed but he was able to get us up and running with a temp fix. He came back next day with the correct part and got it installed.

Also, he didn't try to upsell us on anything like many HVAC companies do these days. I highly recommend him and Delta T.

Josh was amazing from start to finish. He was extremely informative and thorough, taking the time to perform comprehensive testing rather than just giving us a quick estimate. He walked me through multiple options, explained the reasoning behind his recommendations, and patiently answered all of my questions. He was also incredibly prompt and had a detailed bid to me the same day. On top of that, Josh was personable, respectful, and never made me feel pressured. Even though we went in a different direction based on the equipment fit for our particular house, the experience with Josh and PS Cool was excellent. If you're considering them for HVAC work, I would absolutely recommend having Josh come out.

Yvette, who runs the office, was equally impressive--she answered every question we had and always responded promptly. The technicians were outstanding as well. We purchased our Highlands Ranch home in 2020, and since it was built in 2003, the original AC and furnace were long overdue for replacement. PS Cool Heat offered a very fair price on a new Lennox HVAC system. The dual‑stage air conditioner now cools our home within minutes--our old unit often took 45 minutes or more. This team is the real deal: professional, responsive, and truly pleasant to work with. Do yourself a favor and at least reach out to them. You won't be disappointed.

My mother-in-laws air conditioner was not working so I decided to call them for service on her nearly 40 year old system.

Tristan had the problem diagnosed within a couple of minutes and showed me exactly what had happened and why the AC wasn't working. He was able to repair the unit with a new part and Did Not over-charge. I know how hard it is to find good help these days. I think all business owners struggle with this. I just want Mountain Air to realize they are in good hands and have a definite "keeper" with Tristan. He had a great attitude and represents Dan and team well! Many thanks and much appreciated!

Following a quick search on social media, many of our neighbors recommended Emporia. They had a technician out to our house in less than two hours, who quickly diagnosed the problem. Nicholas was simply fantastic! He indicated that he could get the part we needed but couldn't likely come back until the following Monday. I told Nicholas that we were having our 5 month old grandson for the weekend and I was concerned how cold it would be for him. Nicholas thought about it for a moment and said something similare to, "I try to figure out a way to get this done." To do this, I think he had to get it cleared with his boss since it would likely require him to work late. Sure enough, later that afternoon, Nicholas returned and fixed the furnace. We are so impressed with Nicholas and Emporia. I feel very comfortable recommending Emporia to anyone, and if you can get Nicholas - even better. The service was great, the price was fair, and I'm sure they know they could have overcharged me and I was in a position that I would have to pay it. They did not. Thanks guys! You are very much appreciated!
