Chris was great in helping us get some electrical issues squared away.  We contacted 4 people, 2…read morewho were well rated on Angie's List.  Chris was the most professional of all of them, the most flexible, and had very reasonable prices.  Among everyone that visited, Chris was the person who didn't make assumptions, who checked everything, and was very happy to explain everything that he found and what had caused it to happen.   Instead of treating us as "just another dumb homeowner" he really was interested in making sure that we knew what was going on. During the trouble visit, he fixed 2 light fixtures and 2 outlets that were not functional.  He gave a great quote on correcting the wiring on a 3-way that was split between floors.  Next time I need service I'm not even going to bother calling anyone else. -Bryan & Wu Schaefer, St Louis MO 63116

King did a fantastic job with our new HVAC system. We are all electric with a heat pump and I was…read moreconcerned about how all that would go. We had a very old system and desperately needed the upgrade. Every single part of our experience was seamless, professional, and excellent! We called on a Friday and we had a crew working the next week, completing the process in just two days. From the start of working with King, it was easy! John D. came to our home, explaining what we had, what was needed and what options we had to get the most from our hvac system. He was polite, professional and very informative. He wasn't just selling stuff to sell it, he really gave us confidence from the start, knowing his information and being able to explain the options and different brands and systems to us. We were even able to get a new filter system that only needs changed once a year to save on replacement costs. We also now have a working humidifier system too! Then meeting the install pros, like Mike W. He continued to add to my confidence in King Heating and Cooling. He came in very friendly introducing himself and his crew (he did this any time a new tech would come out), explaining what would happen, answering questions I had going into the install day, and was very respectful of my property (asking where they could park, laying down protective sheets to cover flooring & stairs and they all wore booties over their boots to make sure and show the upmost respect and politeness). I appreciated that and actually didn't even expect that! I also was grateful of how John D came to make sure all was going well on the job. What company do you know of that provides this type of quality assurance, none that I know! King is different, they're not only experienced, but they go above and beyond for their customers! Mike W made sure to help set up our new thermostat and walked me through the app process and answered all questions. The whole experience was exceptional! It's a huge purchase and you want to have confidence that every part of the process is smooth. King knows just how to do that. They have a very kind office staff that welcomes you in and creates a pleasant phone experience too. They also provide updates any time your technician is coming out, sending you a text with their picture and a bio about them. I loved that. Taking extra safety precautions like this is important in our world today. I'm so happy we went with King Heating and Cooling! We'd recommend them to everyone! From start to finish, you will be taken care of with professionalism, expertise and excellence!

It seems that when people are satisfied they don't bother to review things online. Only the chronic complainers do that. When I have an HVAC problem in that area, I will call these guys.

Owner stated multiple times over the course of the last 2 years that the unit would be replaced only to find out that that was being said to sweep the problem under the rug.

I called to see if they could get it that day since my A.C. went out. The guy I talked to said that it would be expensive due to it being a "same day emergency delivary". He told me it would be about 85 dollars. The other place with overnight charge was 45 and 15 of that was overnight delivery fee. He then began to say "well why would you do that to someone"? As if to say I was screwing the other company over and I may do it to them without even asking questions to find out why and just assumed the out come. He was very rude. I have worked in parts before for a good while. His mark up was way over 30%. I know better. Quite honestly I couldn't believe he was talking to me that way. Welp needless to say I did use the part that was ordered and they lost the sale because of it. I had heard they are a rip off but wanted to give them a shot. Now I know. Avoid these people at all cost, which is much higher than everyone else apparently.
