A package unit is a self-contained HVAC system that houses the heating and cooling components in a single outdoor cabinet. These systems are common in modular homes, homes with limited indoor space, and properties using rooftop or pad-mounted HVAC.
Unlike split systems, which have separate indoor and outdoor units, package units simplify design, reduce indoor noise, and are easier to access for service—all reasons why many Knoxville homeowners rely on them for year-round comfort.
Package units are reliable, but they can still run into issues—especially without regular maintenance. If you're experiencing problems, our skilled technicians can diagnose and fix the issue quickly and affordably.
These symptoms may be caused by a range of issues—from electrical problems and refrigerant leaks to failing blower motors or dirty coils. Whatever the cause, we'll identify it quickly and provide a clear repair recommendation with upfront pricing.
Our technicians are trained to work on all types of residential package units, including:
We arrive on time, diagnose accurately, and carry most common replacement parts in our service vehicles. That means we can often fix the problem on the same visit, getting your system back online without delay.
Every repair includes a complete system check, so you know your system is running safely and efficiently when we leave.
HVAC issues don't always wait for business hours. That's why we offer limited emergency repair services for package units in Knoxville. If your system fails during a heatwave or cold snap, give us a call—we'll do everything we can to get you fast help when you need it most.
The best way to avoid system breakdowns is with routine maintenance. Our comprehensive package unit tune-ups are designed to keep your system clean, safe, and operating at peak efficiency—no matter the season.
We recommend scheduling biannual maintenance—once before cooling season and once before heating season—for the best results.
Routine service isn't just about preventing breakdowns. It also helps your system last longer, run more efficiently, and operate more safely.

At J.C.'s Heating & Air, we understand that homeowners and businesses have many questions about package unit repair and maintenance. Below, we've compiled some of the most frequently asked questions to help you make informed decisions.
A package unit is an all-in-one heating and cooling system with all major components—like the furnace, coil, and compressor—housed in a single outdoor cabinet. It connects to your home's ductwork and delivers year-round comfort using either electric, gas, or dual-fuel technology. They're common in modular homes, small homes, and rooftop applications.
We recommend biannual maintenance—once in the spring before cooling season and again in the fall before heating season. Regular tune-ups help catch issues early, maintain energy efficiency, and extend your unit's lifespan.
During a package unit tune-up, our technicians will:
This ensures your system runs safely and efficiently all year long.
Common symptoms include:
If your unit shows any of these signs, call us for a professional assessment.

But if the system is older, needs frequent repairs, or has a major component failure (like a compressor or heat exchanger), replacement may be the smarter long-term investment. We'll always provide an honest recommendation based on your system's condition and history.
