LET'S GET IT RIGHT
Your project isn't one-size-fits-all.
Planning three systems, mixing sizes or working with a tricky delivery? Send us your ZIP code, spaces and installation details. We'll build a package that makes sense.
Straight answers. Confident decisions.
Are these multi-zone systems?
No. Each included system has its own indoor unit and outdoor condenser. Choose capacities based on the needs of each space, not the discount.
What does the accessory pack include?
One white MLG450 LineGuard kit per system and one MMCK01 Care Kit per package. Each LineGuard kit covers approximately 12 feet of exterior route. Extra cover may be needed for a 25-foot line. Shared cleaning tools can be used sequentially; consumables may need replenishment.
Is delivery included?
Yes. Standard freight is included for buy-now packages in the contiguous U.S. A $149 LTL freight surcharge applies to Oregon, Washington and Idaho. Remote locations, special delivery services and redelivery may cost extra. Contact us before ordering if your delivery needs special arrangements. For packages marked for a quote, we will confirm the delivered price before you purchase.
Can I use another discount?
Project Pack savings are already reflected in the displayed price. Eligibility for any other offer is determined at checkout.
What makes this a Project Pack?
Each package pairs eligible 5th Gen E-Star single-zone equipment with one white LineGuard kit per system and one Care Kit per package. Choose a single-system or multi-system package to fit your project.
How long is the offer available?
The offer ends October 31, 2026 at midnight Central (the start of November 1), or earlier if eligible stock or manufacturer funding ends.
