German-engineered inverter technology in a self-contained package system. Champion Air carries Bosch for package units only — every packaged configuration Bosch offers.
Package Units 101
What is a package unit?
A package unit is a complete heating and cooling system in one self-contained outdoor cabinet — compressor, coils, and blower together — installed on the roof or a ground pad. Only ductwork and electrical connect to the house. A split system, by contrast, divides the equipment between an outdoor condenser and indoor components in a closet, attic, or garage.
Why that matters in Phoenix: a huge share of Valley homes — especially older homes and many in 55+ communities like Sun City — were built for rooftop package units, with no indoor space reserved for HVAC equipment. If your home has a unit on the roof today, a package system is usually the natural replacement. We cover the category in depth on our packaged HVAC systems page, which includes our Lennox packaged lineup.

Inverter Packaged Systems
Package units only: Champion Air carries Bosch exclusively for packaged systems — all kinds — not split air conditioners, furnaces, or ductless heat pumps. For split systems, we install Lennox and Day & Night. Shopping ductless for a garage, sunroom, or multi-zone project? That’s our mini-split specialty.
Inverter Advantage
What makes Bosch package systems different?
Most Valley rooftop units are single-stage: 100% or off. Bosch brought inverter drive to the package format.
All-in-One Design
Compressor, coils, and air handling live in one self-contained outdoor cabinet — only ductwork and electrical connect to the house.
Rooftop or Ground
Installed on the roof or on a ground pad beside the home — the configuration a huge share of Valley homes were built around.
Inverter-Drive Efficiency
Bosch package systems use a fully modulating inverter compressor that adjusts output to the load instead of slamming on and off.
Quiet Operation
Inverter-drive modulation and sound-dampening design keep Bosch package units quiet — per Bosch's published ratings, sound levels reach as low as 60 dBA.
Why does inverter drive matter on a Phoenix roof?
Because your rooftop unit works the hardest during the most expensive hours of the day. A modulating inverter compressor ramps output up and down in small steps to match the actual load, so it can hold a steady temperature at partial capacity instead of hammering on and off through a 115° afternoon — which helps with both comfort and APS/SRP time-of-use bills.

Bosch FAQs
Package Unit Questions, Answered First
What is a package unit in HVAC?
A package unit (or packaged system) is a complete heating and cooling system built into one self-contained outdoor cabinet, installed on the roof or a ground pad. Unlike a split system — which pairs an outdoor condenser with indoor equipment — a package unit keeps everything outside, with only ducts and electrical running into the home.
Why are package units so common in Phoenix?
Many Valley homes — especially older ones and a large share of homes in 55+ communities — were built without closets, attics, or garage space for indoor HVAC equipment, so builders put an all-in-one unit on the roof. If your home has a rooftop unit today, a package system is usually the natural replacement.
What makes Bosch package units different?
Inverter drive. Bosch builds its packaged systems around a fully modulating inverter compressor that continuously adjusts capacity to what your home needs, rather than cycling at 100% or off. Per Bosch's published ratings, that delivers efficiency up to 19 SEER2 with sound levels as low as 60 dBA — a serious upgrade over the single-stage rooftop units most Valley homes started with.
Does Champion Air sell Bosch split systems, furnaces, or ductless heat pumps?
No — package units only. We carry Bosch exclusively for packaged systems, in all the packaged configurations Bosch offers. For split-system air conditioners, heat pumps, and furnaces, our lines are Lennox and Day & Night.
Who installs Bosch package units in Phoenix and Scottsdale?
