PHC is primarily a residential HVAC service company. Our goal is to keep you comfortable. We do this by supporting your existing heating and cooling system operating for as long as is safe and reasonable. Only when your equipment has outlived its' useful life will we recommend replacement. We service customers in Johnson County, Kansas exclusively. By limiting our service area, we can provide more prompt service. When you call us, you will get professional expertise, experience and technology to handle your heating and cooling problems, large or small.
