About Us

My name is Mark London and I am the owner of London Mechanical Heating and Cooling.

We are a family owned and operated business, offering 25 years of industry experience.

We take pride in treating our customers like family. Our goal has always been to provide the highest quality of service, installation and customer service to our clients, giving them peace of mind in the investment of comfort.

We know that time and cost are crucial, that is why we strive to go beyond our client’s expectations, leaving them with 100% customer satisfaction.

Our company operates in Will County and the surrounding areas. We understand the importance of responding quickly, and in most instances can offer a same-day appointment.

We work hard to ensure that any disruption to your home or business is kept to a minimum, as it is our aim to fix your issues on the first visit.
