The Installation Is What Makes the Equipment Perform

When it comes to AC installation in Palatine, a top-of-the-line air conditioner installed incorrectly will underperform from day one. Improper refrigerant charge, poorly sealed duct connections, a mismatched blower speed, or an incorrectly sized unit can add up to a system that runs constantly, struggles to dehumidify, and wears out years before it should. This is why we put as much emphasis on the installation process as we do on the equipment we recommend. Every installation Five Star performs follows manufacturer specifications and industry best practices, and we don’t consider the job done until the system has been tested and confirmed to be operating correctly.

Sizing Your System the Right Way

Square footage alone doesn’t determine what size air conditioner your home needs. A proper load calculation factors in ceiling height, insulation levels, window area and orientation, the number of occupants, and the condition of your existing ductwork. Skipping this step leads to systems that are either oversized, causing short cycling and humidity problems, or undersized, leaving the system running nonstop on peak summer days. Before we recommend any equipment, we do the math. You’ll end up with a system that was genuinely designed for your home, not just the closest available size on a price sheet.

Equipment We Install and Stand Behind

Five Star installs Trane and Mitsubishi Electric equipment, two brands with strong track records for reliability and efficiency. Trane offers a broad range of central air systems suited to most standard residential applications, while Mitsubishi’s ductless and multi-zone systems are an excellent solution for homes with additions, finished spaces without existing ductwork, or rooms that are consistently harder to cool. We’ll walk you through the options that fit your home and let you make an informed decision without the pressure.

New Construction, Replacements, and Add-Ons

Our installation work covers a range of project types. If you’re replacing an existing central air system, we handle the full removal and disposal of the old equipment along with the new installation. If you’re adding cooling to a space that didn’t previously have it, we can assess your ductwork and infrastructure and outline what’s involved. We also work on home additions and finished basements where a ductless solution may be the most practical route. Whatever the project, we’ll give you a clear picture of the scope and cost before any work begins.

Frequently Asked Questions
How long does a typical AC installation take?
Most standard central air installations are completed in a single day, usually between four and eight hours depending on the complexity of the job. Ductless installations vary based on the number of zones and how accessible the installation areas are. We’ll give you a realistic time estimate when we provide your quote so you can plan accordingly.
In many cases, yes. However, older ductwork that is leaking, undersized, or poorly laid out can limit how well even a brand-new system performs. As part of our installation process, we assess duct condition and let you know if any modifications would meaningfully improve efficiency or airflow. We won’t push unnecessary upgrades, but we’ll be honest if the ductwork is going to hold the system back.
