M&K has been providing heating and cooling services for London and the surrounding communities since 1983.

What Sets Us Apart

70% of HVAC issues stem from improper installation. We make sure that when we perform a central air conditioning installation, it’s done Just RightTM.

We know how it feels to invite a strange person into your home, so we make sure to treat you and your home with the courtesy you’d expect from a company with a We Respect YouTM guarantee. We promise to be polite and punctual and clean up after ourselves when we are finished with your AC install.

Our team has G1, G2, 313A & 313D, 308A, ODP, Wardflex, and Supervisor Training Program & IHSA Health and Safety Education Program for Contractor Safety Essentials certifications, and all our technicians are Right TimeTM certified. We undergo continuous training to ensure we can provide you with the best possible AC installation service.

Our customers have given us a 5-star rating on Google, so you know we work hard and don’t quit until the job is done right. We take pride in our work and make sure that pride is reflected in our handiwork and craftsmanship.
