Our Services

DuAll Heating & Cooling is family owned and operated with over 20 years serving residential and light commercial customers in Bolingbrook, Naperville, Plainfield, and Romeoville. With hard work and dedication to honesty and reliability, we’ve grown into one of the Bolingbrook area’s leading HVAC companies. We’re big enough to offer a full range of products and services, but we still treat our customers like family.

To put it simply, we sell, service, and maintain all the mechanical systems that contribute to the environment inside your home:


DuAll Heating & Cooling provides installation, repairs, and routine maintenance on gas and electric furnaces, boilers, and radiant heating systems. We clean furnaces and boilers to prolong their service life, and make necessary adjustments to maximize performance. We can replace old or malfunctioning heating systems with state–of–the–art high efficiency models. Our service also includes installing or adjusting thermostats and zone controls integrated with the heating system.

Air Conditioning

We install and service all types of central air conditioning units, and ductless mini–split systems which have the evaporator coil on the inside and the condensing coil on the outside. We clean the condenser coil, ducts, and other components of the system and check refrigerant levels.

Indoor Air Quality and Air Purification

We’ll make sure your indoor air is clean, balanced for humidity, and free of allergens. We install and service air cleaners, humidifiers, dehumidifiers, and UV germicidal lights for killing bacteria and other airborne microorganisms. We also install and service energy recovery ventilators that conserve heating energy and precondition outside air before it enters your home.

Water Heaters

We handle all types of repairs on traditional storage tank water heaters, and we install new heaters at very competitive prices. Don’t buy a new heater before checking with us. We also install high–efficiency tankless water heaters that provide an endless supply of hot water on demand, without the energy loss associated with tank–style units.

Light Commercial HVAC

We provide service and preventive maintenance on light commercial–grade HVAC systems, including rooftop units.

Expert Service

As a full service HVAC company, our goal is to make sure that your indoor environment is comfortable, clean, and safe. We’ve been servicing homes throughout the Bolingbrook area for over 12 years, so we’re familiar with the demands placed on heating and cooling systems. If you’re a first time customer, we understand that we must earn your trust by providing you with courteous, efficient service. Give us a call if you need work on your heating or cooling system, or if you’re thinking of installing a new HVAC appliance. You won’t be disappointed.
