A.B. May
Kansas City, MO


Aleda and Bill Posladek founded A.B. May when they purchased May Furnace Company in 1959. They renamed it A.B. May (“A” for Aleda and “B” for Bill) and set out to offer Kansas City exceptional home service with a few employees and four trucks.

We have expanded to offer Heating, Cooling, Plumbing, Drains, Electrical, and Appliance repair services. A major development for us came in the mid-1970s when we pioneered one of the first homeowner warranties in the industry. Today, we give thousands of Kansas City homeowners a plan to simplify home service through our Home Warranties and Service Plans. Four core values guide us both in the office and inside homes around Kansas City:

        • We build lasting relationships.
        • We overcome obstacles.
        • We serve others.
        • We build trust.
