Lennox® Mini-Split Systems | The Perfect Solution for Consistent Whole-Home Comfort

Ductless mini-splits combine the size manageability of window A/C units with the cooling and heating brawn of conventional central systems. They accomplish this by utilizing discrete indoor air-handling units (AHUs) that are sized for the room (zone) where they are intended. This point-of-use cooling and heating capability allows you to condition ductless zoned areas as needed for total comfort control and lower energy bills.

You might consider a mini-split HVAC system for your Iowa if your existing system can't do the job of heating and cooling certain rooms in your house, or if you're adding onto your home without extending the ductwork. A cost-effective and energy-efficient way to handle this situation is to install a mini-split HVAC system or heat pump. A mini-split HVAC system is a ductless heat pump (or just A/C in some cases) that consists of three main components - an outside condensing unit (as in a standard split-system heat pump or A/C), an indoor air handler (or multiple air handling units) and a conduit line that connects those two main components.

Lozier Heating and Cooling | Lennox® Mini-Split Systems

Lozier’s Mini-Split Systems provide homeowners with a unit that yield consistency to temperature-sensitive rooms. Our systems are perfect for spaces like sunrooms or add-on rooms where installing ductwork isn’t ideal. Here are three scenarios in which you might want to look into a mini-split HVAC system:

If your existing system cannot handle your new space and you don't want to replace everything. Your old furnace and air conditioner should have been installed based on the precise heating and cooling loads of your home. Additions and room extensions change these loads, and your old system may not be big enough to cost-effectively take on the increased loads. This means you will need to either do a complete upgrade of your existing central equipment, or install a mini-split system to handle the additional loads.

If the spaces have different heating and cooling needs. Extending existing ducts or heating pipes into a new space can cause temperature discrepancies in your house. This can be due to distances from the air handler, insulation differences, or a number of other factors. However, a mini-split system has its own thermostat, allowing it to operate independently of the rest of your home and preventing you from having any temperature balancing problems.

Better heating and cooling efficiency. Ducted systems experience significant energy losses, both through leaks in the ducts and heat conducting through the think duct walls. A mini-split heat pump doesn't use ducts, so there's no need to worry about these types of loses.

All mini-split systems (whether it’s for heating or cooling) include these features:

  • Variable-capacity operation for a more efficient and consistent comfort that changes with the weather
  • Wireless remote control for constant comfort that’s easily adjustable
  • 5-year limited warranty on covered components

  • Versatile in varied climate conditions, maintaining performance through ambient temperatures below freezing or in excessive heat  



SEER stands for the seasonal energy efficiency ratio, which is calculated by the cooling output during a typical cool season divided by the total electric energy input during the same period. The higher the unit’s SEER rating the more energy efficient it is.


HSPF stands for the heating seasonal performance factor and is used specifically for heat pumps. This score is a ratio of heat output over the heating season to watt-hours of electricity used. The higher the unit’s HSPF rating the more energy efficient it is.
