26 YEARS. ONE OWNER. EVERY JOB.

All 4 One Heating & Cooling provides trusted HVAC, plumbing and indoor air quality services across the Kansas City area. We help homeowners and businesses stay comfortable with reliable repairs, routine maintenance and complete system installations, working out of our office at 5828 Woodland Ave in Kansas City, Missouri.

Owner Antoine Mitchell has repaired, installed and maintained HVAC and plumbing systems for 26 years and personally oversees every job. That matters in a trade where the quality of the work depends almost entirely on the person doing it, and where an owner who still knows the equipment can tell the difference between a repair that will hold and one that will not.

All 4 One holds active contractor licenses in both Johnson County, Kansas and Kansas City, Missouri. That dual licensing means the same team can legally handle a job on either side of the state line without bringing in a subcontractor — one company, one crew, whether the address is in Overland Park, Olathe, Lee's Summit or Kansas City itself.

License coverage, 26 years of hands-on trade experience and a 4.9-star rating across 63 Google reviews give homeowners and businesses a documented reason to trust the technician standing in their driveway, not just a company slogan. Homeowners can confirm current license and insurance details directly with us before scheduling any job.
