From tune-ups to full replacements, Five Star keeps Palatine homes cool all summer with expert AC service you can count on.
Illinois summers are hot, humid, and unforgiving on residential cooling equipment. A system that’s been neglected through the winter or is quietly developing a problem is likely to fail at the worst possible moment, usually during the hottest stretch of July when demand for emergency service is at its peak. Five Star has been helping Palatine homeowners stay ahead of that scenario, providing reliable air conditioning service across every stage of a system’s life from routine maintenance to full replacement.
Our technicians are licensed, insured, and trained to work on all major residential brands. We give you an accurate diagnosis before recommending any work, an upfront cost before we start, and a satisfaction guarantee when the job is done. Whether you’re dealing with an urgent problem or planning ahead for the next season, Five Star is the one call that covers it all.
Every service call starts with a thorough evaluation of your system. We don’t skip steps or replace parts speculatively. Our technicians check refrigerant levels, inspect electrical components, evaluate airflow, test controls, and assess the overall condition of the equipment before drawing any conclusions. Once we know what we’re dealing with, we explain it in plain language and give you a clear cost before any work begins.
We service all major residential brands including Trane, Carrier, Lennox, Rheem, and Mitsubishi Electric. For new installations and replacements, we install Trane and Mitsubishi equipment and perform a proper load calculation to ensure the system we recommend is genuinely matched to your home rather than just the closest available size.
Not every home needs the same cooling solution. A standard central air system works well for most homes with existing ductwork, but homes with additions, finished spaces, or rooms that have never cooled properly may benefit from a ductless mini split system that delivers targeted comfort without the limitations of a ducted setup. Five Star installs and services both, and we’ll give you an honest assessment of which approach makes the most sense for your specific situation.
For homeowners considering a new system, the installation itself is just as important as the equipment. An improperly sized or installed air conditioner will underperform from day one regardless of the brand. Five Star performs a full load calculation on every installation to make sure the system we put in is the right fit for your home’s size, insulation, and layout.
Five Star serves homeowners throughout Palatine, Arlington Heights, Hoffman Estates, Rolling Meadows, Schaumburg, Des Plaines, and the surrounding northwest Chicago suburbs. Our technicians are local, familiar with the homes and systems in this area, and available for both routine service and 24/7 emergency calls when something can’t wait.
For generations, homeowners in have trusted us for honesty, quality, and reliability, but don’t just take our word for it.
