Pioneer Mechanical, LLC., Festus MO

A contractor recommended this service for boiler problems. First I left a message and never got a returned call. Next I called the St. Peters office where a man told me the only technicians they had for boilers were in the St Peters office -to call that number. I hung up and saw that WAS the office I had called. Time passed. I called again today and a woman answered who said she was working from home (not sure why -good weather day today) then revealed it would be a NONREFUNDABLE $400 just to have tech.come out and that amount is NOT applicable to any work that needs to be done. THEN she informed me "Oh, it looks like we're all booked up not taking any new custo" yes, she actually HUNG UP ON ME BEFORE FINISHING HER SENTENCE. This is THE WORST HVAC EXPERIENCE I've ever had in 26 years and didn't even get service yet!

Our AC wasnt working and I called around 1030. We got someone out to our house at noon the same day and was able to replace the part that went bad all within 30 mins. The technician did an amazing job explaining everything as he went. I would highly recommend them to anyone. If I ever have any more issues I know who I gonna call. Thank you!

Had a new hvac system installed. They were prompt and very professional. Cleaned up and very courteous. Would highly recommend! Very happy with they’re work!

We have been using Steve and crew at Pioneer for years. They have always been professional, courteous, on time, and perform quality service. We will never look anywhere else for our heating and cooling needs!

Our home had the original builder grade AC unit that was installed 20 years ago. It was time to upgrade our system. Steven is very knowledgeable and answered all our questions when he came out for our consult. He recommended the best plan for our house and our budget. Steve and Jenna provided very prompt communication during the entire process. Our install day was seamless, professional and friendly. Pioneer Mechanical did an amazing job!

Was able to respond right away. Very professional and knew what he was doing. Friendly. I am Very happy with this company. I Highly recommend them.

Honesty goes a long way with me. Never met these people. But had a ac issue today over 100 degrees outside full time single father life. Everyone else I called wanted to charge me tons to come out after hours etc. This guy calls free of charge tells me something to go try not to waste my money. Tells me this heat a common problem and it worked.can't say how thankfully I am seeing honest good bussiness people will use now for anything I need. Great honest service.

Pioneer Mechanical installed an A/C unit, an air handler, a thermostat, and a heat pump in our home, and we are glad we chose Pioneer. Mike and Keith were friendly, professional, on time, and thorough. We are extremely pleased with the work they did and our equipment. If you are looking for a HVAC company for your home or business HVAC needs, then look no further than Pioneer Mechanical. We will be recommending them to our friends and family. Thank you, Pioneer!

The foreman Mike C.answered my many calls and questions with a very professional attitude. He was very clean and informative on any changes that happened during the installation. I am a tradesmen and his work is some of the best that I have seen for residential work. His assistant Keith B.was equally as professional. I recommend the products they use and the price point as well. I also really am happy with them taking care of my Ameren MO rebate. Katie form the office was a huge help. Thanks again for a great experience.

Pioneer Mechanical has been here for my family and I since we moved into our house in 2017. Any issue we had, big or small, they were there to help, and they always do their very best to work with you to get you what you need no matter what your situation is.
Their knowledge, professionalism, and most of all, their transparency are why I will keep giving them my business. Thank you!

Installed a new boiler. I was a little nervous about how much lower their bid came in, but they were great to work with and the system is running great so far. I highly recommend!

Everyone involved from the office to the field employees were great. They communicated everything and made sure I understood the process. Installers were very prompt and did a very nice job. Cleaned everything up. Would recommend them to friends and family.

Great service and rates! Steve, Katie and the technicians were all great to work with. I will definitely use them again.

Great guys organized, cleaned up areas of all debris from old unit. And thanks for the quick response when I called and arrived at my house. And it was Memorial Day weekend. Me and my wife give you a big thank you.

The guys Steve sent out to do the work did exactly what he said they would do. Had to have the whole system replaced. (15 years on the old one) After 6 months my electric bill is almost half than from the previous system. Also, Katie was able to get us more of a rebate from Ameren than we had thought we were getting. Great job guys.

Mike and Keith replace a mini split heat pump for me and did a superb job. They both did an excellent job and were very personable. I would highly recommend this company. They worked for me a couple of times and haven’t been disappointed. Thanks Mike and Keith.

Great company! We used Pioneer to service our A/C units and furnaces on several occasions, all great experiences. They quickly repaired our A/C when it stopped working last summer. They also replaced our furnace late last year. Katie was very kind answering all of my questions about the replacement. Keith, Mike C.and Mike D.did a great job servicing the units and on the replacement. I highly recommend Pioneer.

Fabulous company. Returned my call in 3 minutes. Keith was on time and explained everything. My air was fixed in 36 minutes!
