Doug's Heating & Air Conditioning

For more than 70 years, we’ve helped homeowners and businesses across the Quad Cities stay comfortable. We serve customers in Moline, Rock Island, Davenport, Bettendorf and the surrounding Quad Cities area. We take pride in providing enduring service and value while treating our customers’ time and property with care. With more than 15 service and installation vehicles, we’re prepared to respond 24 hours a day, 365 days a year, including weekends and holidays. We also offer convenient two-hour scheduling windows to help reduce waiting.

For residential customers, we sell, install and repair traditional, ductless and geothermal heating and cooling systems. We were among the first in the area to install and work on geothermal systems. Our licensed technicians are available around the clock for emergency service, and we can review personalized equipment replacement options when it’s time for a new system. We also sell, install and repair generators, and we install air-quality systems and insulation. Furnace parts installed by our factory-trained technicians are backed by a 10-year warranty, and our 7-Point Guarantee helps keep us accountable for customer satisfaction.

We also provide commercial heating, air-conditioning and ventilation services for businesses and restaurants throughout the Quad Cities. Our work includes heating and cooling system maintenance, equipment service, replacement and installation, as well as the development and maintenance of ventilation systems. We sell and service food-service equipment, including refrigeration units, ice machines, coolers and commercial ovens. When an urgent commercial cooling problem arises, our technicians are available 24/7. We also offer proactive maintenance solutions designed to help customers reduce the likelihood of unexpected emergency calls. Whatever the job, we aim to provide fast, friendly, clean and efficient service.
