Package Unit Replacement Done Right—Safe, Efficient, and Built to Last
Package units typically last 10–15 years, but they eventually become inefficient, unreliable, or unsafe. We’ll help you determine whether a repair or full replacement makes more sense based on your system’s age, condition, and performance. We install top-tier systems designed for Oklahoma winters & summers, sized correctly for your layout, and compatible with your existing ducting.
When to consider replacing your package units:
- Repairs cost more than 30–40% of replacement
- Rust, corrosion, or cracks in the heat exchanger
- Frequent shutdowns or pressure problems
- Home isn’t heating evenly anymore
- Older unit lacks safety shutoffs or modulating controls
- Parts for your current unit are hard to find or discontinued
- Annual maintenance can’t keep up with issues
- You’re remodeling or adding square footage to the home
- You want better efficiency and lower utility bills
- Local code requires an upgrade for resale or insurance
Don’t wait for cold weather to find out your Package Unit isn’t ready.

Frequently Asked Questions
About Package Unit Services
What’s the difference between a package unit and a condenser and furnace?
A Package unit heats and cools air and blows it through ductwork, much like a traditional system, but doesn't require an indoor furnace or air handler. Package units are great for homes that dont have room for or just dont want an indoor furnace. Traditional systems with indoor furnaces are more common in Oklahoma homes, but package units are still widely used, especially in older or custom builds.
How do I know if my Package unit is working efficiently?
Signs of poor efficiency include longer run times, uneven heating, increased gas or electric bills, and strange smells like burning or mildew. If your package unit is more than 15 years old or hasn’t been serviced annually, it may be running well below its rated efficiency. We can perform a full analysis and system check to see if a tune-up or upgrade is warranted.
Can you repair or replace older package units?
Yes. We work on older Package units as well as modern modulating-condensing systems. If your current unit is still structurally sound, we can often replace key components like pumps, controls, or valves to extend its lifespan. If it’s leaking or corroded, we’ll recommend a safe, efficient replacement and take care of the removal and install.
Do package units work well with modern smart thermostats?
Most new package systems are compatible with Wi-Fi and programmable thermostats, though compatibility depends on zoning, wiring, and system design. We’ll evaluate your setup and install a smart control system that works seamlessly with your unit and your comfort needs.
Is package unit service more expensive than furnace service?
Package system work tends to be more specialized, so yes—repair or install costs may be slightly higher than with traditional systems. However, many homeowners find the external equipment and space savings, worth the investment. We’ll always provide a detailed estimate and explain your options before beginning any work.
