I've used Stewart's several times over the years. They are quick, responsible, and always willing to offer options where it's possible. For instance, I had all the duct work replaced for better efficiency (suggested by an energy audit from KU.) Stewart's made an assessment, suggested maybe I not replace--but if I was going to, to wait until they had a lull in their schedule, so pricing would be significantly less. I've used them for almost 20 years.

In that time they've replaced our gas furnace, fixed our AC (and suggested we keep it until it REALLY broke--it was really old but well built), replaced all duct work. and in the midst of the pandemic rebuilt the motor on that old AC to keep it running until the order for a new one came through. I can't sing their praises enough. They're my "Yeah, I got a guy."

The local "Big-Box" HVAC company (let's call them Kobe) came out to diagnose a furnace issue, quoted me $6,600 for replacement, and gave me the old scare-sale tactics. So, I called one of the "free second opinion" HVAC companies, who didn't bother diagnosing the problem, and just quoted me $4,600 for the same system quoted by "Kobe." I decided to give it one more try, so I called Stewart. They sent a friendly and knowledgeable tech out who did some testing and diagnosis, and recommended replacing a blower motor-- for just $600, rather than $4,600 or $6,600.

When I told him what the other companies had quoted, he said, "They work on commission. I don't. Your furnace is fine, there's no need to replace it." Stewart has earned my business for life! When it is eventually time to replace this old furnace, I know who I'll be calling.

Stewart's came for the first time. They were highly recommended by friends and I can see why. Not only did they maintain my furnace they noticed that a pipe was leaking carbon monoxide. This had been going on a long time and no other repairpeople had noticed. He told me what to do. I really appreciated this extra attention to detail. M. Tarpey

No experience with HVAC in Nicholasville before. Tried Stewarts HVAC and was very impressed. Call center staff were friendly and had a repair unit to my daughter's home in less than 2 hours. Freddie ( tech) was amazing! Diagnosed the issue quickly, provided detailed info on needed repairs, and finished the job promptly. Cost of repairs was reasonable too. I don't usually leave reviews, but this service experience was outstanding.

My furnace is possessed.something has gone wrong with it every year. Last year I tried Stewart's for the first time. They replaced some things, and I was hopeful that it was fixed once and for all. But this year, it was back to it's old tricks. Freddy from Stewart's came out this time, troubleshooted, and figured out what may have been the underlying problem the whole time. He bypassed the problem switches and offered to let it run for a week to prove it would work, while I decided if I wanted to replace with a new furnace or repair.

It worked all week so I decided to repair one more time. I'm hopeful this is the final fix, because if it messes up again I'm going to put my foot through it lol. Stewart's prices are reasonable, they have always arrived expeditiously and on time, and wore a mask. They won't try to sell you a furnace you don't need, and really work with you to give you all the best options. The office staff and everyone I've spoken with have been super nice and helpful. Thanks for taking the time to diagnose my possessed furnace!
