Sewer Surgeon, LLC, is family owned and operated! We have been serving our neighbors for several years. We take pride in our work and pay extra attention to detail. We promise to treat your home as if it were our own. Call us today!

"Professional, knowledgeable, patient, very thorough and went the extra mile. They also gave us a very reasonable price for all the hard work that was done. They arrived earlier than anticipated and called us to ask if it was ok to come out sooner than later. We were jumping with joy! We plan on asking for their help again if we ever need our sewer line cleaned out again. We highly recommend this wonderful family owned business. The staff are amazing. The young lady who called us from the company office was so wonderful and blessed us by being the first one to reach out in order to offer their help. Thank you Sewer Surgeon staff! 😊"

Whether you're dealing with a plumbing emergency or are interested in replacing your air conditioning or heating system, our team at Mission Plumbing, Heating & Cooling is here to help. We have been trusted by homeowners in Kansas and Missouri since 1978, delivering the reliable service that keeps our customers comfortable all year long. Our plumbing and HVAC professionals are licensed, bonded, and insured, and you can count on our expertise in diagnosing and handling any issue you might be having with your home. If you're interested in protecting the environment and saving on your utility bill, we can also talk to you about energy-efficient upgrades and installations.

"PSA: legacy Ultra Heating & Cooling customers, cancel all payments. On June 22nd, Mission Plumbing, Heating, and Cooling sent a technician to diagnose my HVAC system - the AC had not been working for a few days at that point. Since then, they have not called, messaged, or emailed me a single time. I have called 4 times, each time they have said, "I will make sure someone gets back to you right away". My house has been without AC for 17 days due to their lies stringing me along. I have been paying $14/mo for a service agreement since December 2021, and never had any issues with Ultra Heating and Cooling fulfilling their contractual obligations. However, it is clear that Mission PHC has taken on all Ultra customers with their acquisition, and are continuing to take their money every month with no intentions of honoring the service agreement. To all legacy Ultra customers, I would recommend cancelling your service agreement immediately and finding a new, trustworthy HVAC company."
