    Great company and people. They’re the installers of our system when the house was built. We needed service recently for a furnace malfunction covered under warranty. Lightning fast response and reasonably quick repair. We will use Muller again for anything HVAC related.

    Great customer service! Had a furnace issue on a holiday and thought i was going to leave a message and get called back the next day but not only did a person answer the phone u got a call from the original installer of my unit to try to troubleshoot it and see if we could get it running without a service call. Once they realized it needed a part Had it ordered and installed in a very reasonable time.

    We discovered that our furnace stopped working on Thanksgiving night. On Friday morning we left a voice message with the company that we had used for over 20 years and had an annual service contract. They responded by text, while we were traveling to the Platte County semi-final football game in St Louis, that they were not available and that we could schedule an appointment in Monday. When we got home Friday night our house was cold. We called the company again on Saturday morning and left a voicemail and got a text message that they were unavailable. I then called Muller Heating and talked to a kind technician who offered to help. I received a call within an hour from Ron Muller who was able to help me solve the problem over the phone. Thank you Ron! We will be using Muller Heating for all of our future services and highly recommend your company to anyone!
