• Friendly, professional, thorough, and follows all Covid-19 safety precautions
    Frank M. performed my 6 Month semiannual Maintenance service today on my Geothermal HVAC. He does an excellent job. He is prompt, courteous, friendly, professional, thorough, and follows all Covid-19 safety precautions. He is the best and I always request him.

  • I got other estimates but Weis was by far the most professional and knowledgeable. The install was painless.
    Weis has been maintaining my HVAC system for years, and when a 21-year-old system was ready to be replaced, they gave me a very clear estimate that included everything I needed, complete with rebates and a loyalty discount based on a percentage of my maintenance costs in the past. I got other estimates but Weis was by far the most professional and knowledgeable. The install was painless.

  • They are professional, knowledgeable and everyone is super friendly!

    I've been with Weis Comfort for a few years. I couldn't be happier. They are professional, knowledgeable and everyone is super friendly!
    If you like a particular service person (as I do), you can request them to take care of your system. They arrive on time. Jim will take his time and explain everything to me! Having him come out every 6 months to service my heating and cooling system gives me peace of mind all year that my system will be safe and running smoothly! I would definitely recommend Weis Comfort System!

  • Exceptional quality, friendliness and cleanliness.
    Weis just installed a new Daikin fit system for me with heat pump. The installers were fantastic! Exceptional quality, friendliness and cleanliness. Definitely got what I paid for. Can't wait to see my electric bills drop. Thank you, Weis!

  • I would certainly recommend them and will definitely give them a call next time I need service!
    Weis was able to send someone out the same day I called, which was good since it was in the mid-90s and my AC wasn't working at all! Rich was able to diagnose and fix my AC unit in under 30 minutes, getting our house back to being cool again. They were very upfront about pricing, which was very reasonable. Rich was very professional and courteous. I would certainly recommend them and will definitely give them a call next time I need service!

  • Arrived at the time told, very professional.
    Arrived at the time told, very professional. Quickly found the problem and had the parts on the truck. Problem fixed and the house was cooling down within an hour. Great company, have used them for over 10 years, always happy with the service.

  • Super great experience!
    On time....did the job right...cleaned up all the mess...the initial consultation was short but informative of my choices for my project comparing and contrasting different units. Jim was the point man for that. Super great experience! I would recommend them to everyone. Dr. Neil

  • Weis Comfort Systems arrived within a couple of hours
    Great Service! Called on a 93 degree Sunday when my 91-year-old father's air went out. Weis Comfort Systems arrived within a couple of hours, had the unit fixed and cooling within less than an hour of arriving. Frank was polite, friendly, and most important knew what he was doing!

  • Great experience with Weis Comfort heating & cooling.
    Great experience with Weis Comfort heating and cooling. I hired their St Louis office. The staff was very friendly and helpful. 2-hour service window was nice, compared to other HVAC contractors wanting me to hang around all day. AC was fixed and running within 45 mins. Highly recommended to anyone looking for HVAC repair.

  • Pleasant & Helpful People
    Weis Comfort Systems Inc. has pleasant and helpful people working at their office and in the field. Rich was the tech that visited my home today to do a furnace check. He arrived at the earliest part of his suggested time. He was quick, neat, and I felt comfortable with him being in my home.

  • These Folks Are Pros!
    Thanks to Jim E and the Weis team for the long day of work today! The house is finally cooling down and we'll sleep better tonight because of your work. These folks are pros!

  • We switched to Weis for a better price, but we also gained better service.
    Tony Frisch and the Weis team have been out to our house at least 5-6 times this past year. We have "unicorn" situations with our Mini-Split AC units and our Boiler/Radiators that are older than my wife and I combined. It's never comforting running into HVAC issues when you really need it, but their customer service (Brittany and group dispatching) and knowledge have helped us save money and avoid very costly repairs. We had a Preventative maintenance contract with another large HVAC in our area. We switched to Weis for a better price, but we also gained better service.

  • They worked with us to get it installed professionally & quickly
    Our air conditioner went out and we had a representative from Weiss comfort systems there that day to give us a bid on a new unit. We bought a new air conditioner and furnace. They worked with us to get it installed professionally and quickly

  • It was a very painless process!
    We had a completely new system installed, our previous A/C was a Lennox, this one was 27 years old and was still working hard! They were so courteous and arrived right on time. They completed the job in the time specified, it was a very painless process!

  • Weis Comfort Systems installed a new heating and cooling system in our house
    Not quite a week ago, Weis Comfort Systems installed a new heating and cooling system in our house. The installation was smooth and did not interrupt our normal, everyday activities. The two men who completed the installation were friendly, courteous, and, at times, even entertaining. When the work was completed we spent time talking with the men about the installation and exchanged some personal stories on various topics. We have never experienced service like this!

  • Good to have Weis for services
    The service personnel has been to my home several times since we moved to our new home in 2014. We were unfamiliar with geo-thermal and the people at Weis have explained the workings of the system and backup heat or cooling. Repairmen are always courteous and professional. Good to have Weis for services.

    - John C.

  • Excellent Customer Service
    As a long-time Weis customer, I consider it an exceptional company. They are competent, dependable, efficient and courteous. Weis has installed and serviced our heating and cooling equipment for nearly 20 years. When our thermostat went out on the coldest night of the year, Rich got us warmed up again in short order. Rich is a great example of excellent customer service and a big reason for my confidence in the company.
