"Had an extra tall toilet installed for my elderly mother. It will make sitting down and getting up a lot easier. Thank you Allen for doing an awesome job!"

"I cannot say enough good about this company. This is our second service with this company in the past 2 months. Reasonable prices. We had Jason Becker replace a faucet and shut off valves in our kitchen. He was very personable , quick and efficient. We would not hesitate to call Anton for future work. If it would be a plumbing project, we would request Jason B. We are very glad we found your company and you have very good employees. "

"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done. "

"Called Sam on Friday for quote for water heater replacement. Said he could do Monday afternoon or Tuesday morning. Received call Monday morning to see if he could come on over to do replacement, what a pleasant surprise! Sam arrived shortly after with water heater we discussed & all supplies needed , no running around to pickup stuff. Job completed in timely manner. Old unit hauled off and job site all cleaned. That’s a big deal to me. Will not hesitate to recommend Liberty to friends & relatives ! Thanks Sam , Dave & Roxanne"

"Sam did a major overhaul on an outbuilding at our new shop in Union, MO to turn it into and office. New roof, flooring, repaired lots of water damage, paint, and cleanup. The work was done in a timely manner. Pricing was reasonable. They stayed within budget and let me add on a couple things. 😁"

"Only rating 1 because it doesn't go lower. Had a new unit installed end of Sept 24. First time power goes out on 11/5, no electricity. When tri state sells you a product, they pitch their amazing customer service with all these guarnatees of knowing when your unit is out before you know and having someone there within 24 hours etc. Well, the first call we make we are told it will be the end of Nov to get someone out to look at it. 3 weeks. Nobody shows up. Then we get a call that says "your appointment on Dec 12 has been canceled and the earliest we can get to you is Jan 16th. This is 2.5 months wait to get service to fix a nearly $20k unit, that is upcharged because of the excellent service. You can't get anyone to answer your call. you wait on hold for 20 minutes, then have to leave a voicemail in which you will not get called back. Based on my experience, find someone else and pay less. Even if the service is bad, which it can't be worse than this, you save money! @kohler"
