A & J Complete Service Corp has kept homes comfortable in north-central Illinois for more than a decade. Based in Tiskilwa at 226 West Main Street, the locally owned contractor serves La Salle, Princeton, Henry, Bureau, and Putnam counties. The team holds a 4.8-star average across 21 verified client reviews, reflecting consistent quality in heating, cooling, and indoor air quality work for both residences and light commercial properties.
What distinguishes this contractor stems from manufacturer partnerships and consumer savings programs. As a YORK dealer, the crew installs qualifying equipment eligible for factory rebates up to $500 plus utility incentives reaching $900 on heat pumps and $275 on furnace bundles. Teachers and first responders receive additional discounts reaching $600. Every job carries a 90-day parts-and-labor warranty, rare among regional competitors.
Client accounts reveal why local homeowners recommend the crew. When a Tiskilwa residence faced a furnace failure late evening, technician Matt arrived within an hour and resolved the issue in 30 minutes. Another reviewer described how Matt and technician Gary removed an aging furnace and installed a new system with precise pricing matching the original quote, no hidden fees appeared after completion.
