The HVAC experts at Allegiance Heating & Cooling offer extensive AC repair in New Lenox, IL. Air conditioners have many components that can become damaged with wear and tear. As your system ages, it must work harder, often resulting in breakdowns that become costlier to fix. Prompt air conditioning repair prevents further damage and premature replacement. Our expert HVAC technicians undergo extensive training to diagnose and mend all makes and models.

Common repair issues involve refrigerant leaks, failing thermostats, and damage from overheating. One of the first things we look for in an overheating AC is acid buildup. Acid buildup occurs with refrigerant leaks and failing motors. It can cause system corrosion and the eventual need for a replacement. You can prevent overheating by changing your filter regularly and seeking professional care when problems arise.
