90% Split Gas System

A 90% split gas system is a type of heating and cooling system designed for residential or commercial buildings, offering an efficient way to regulate indoor temperature. The term “split system” refers to the configuration where the system components are divided into two main parts: an indoor unit and an outdoor unit. The indoor unit typically houses the furnace, while the outdoor unit contains the air conditioner and compressor.

The “90%” designation indicates the system’s efficiency, meaning it converts 90% of the fuel (natural gas or propane) into usable heat while only 10% is lost through exhaust. This level of efficiency is achieved through advanced features like a secondary heat exchanger, which extracts additional heat from the combustion gases before they are vented. This makes it significantly more efficient than older or less advanced systems, such as an 80% gas furnace.

The indoor furnace heats air using gas combustion and circulates it through the building’s ductwork. The outdoor unit works in tandem to provide cooling during warmer months, using refrigerant to extract heat from indoor air and expel it outside.

A split system is ideal for areas with distinct heating and cooling needs, offering flexibility, energy efficiency, and cost-effectiveness. Additionally, these systems are compatible with various upgrades, like smart thermostats, to enhance comfort and energy savings. Regular maintenance ensures optimal performance and prolongs the lifespan of this reliable system.
