Gas Split System HVAC Units in Tucson, AZ

A gas split system pairs an indoor gas furnace with an outdoor electric condenser, sharing one duct system. The furnace heats in winter, the condenser cools in summer, and because they are separate units either one can be replaced or upgraded without touching the other.

A package unit contains everything in a single outdoor cabinet, usually on the roof. A split system divides the equipment between an indoor furnace and an outdoor condenser. Split systems are easier to service one piece at a time; package units save indoor space.

Sizing comes from a load calculation, not from square footage alone. We measure the conditioned area and account for insulation, window orientation and the condition of the existing ductwork. Two houses of the same size on the same street sometimes need different equipment.

It depends on the capacity, the efficiency rating, and what the installation involves, including any ductwork repairs, gas line work or electrical upgrades the job turns up. We quote after seeing the house, and the quoted price is the price.

Sometimes. A heat pump paired with a gas furnace lets the heat pump handle cooling and mild heating efficiently while the furnace covers the coldest nights. It costs more up front, so it makes sense where the winter heating savings justify the difference.

A well-installed and maintained system generally gives 15 years or more, though the furnace and the condenser rarely reach the end of their lives at the same time. That is one of the advantages of split equipment: you replace the half that failed.

Always. The gas line is connected and leak tested, venting is confirmed to draw properly, and we run a combustion and carbon monoxide check during commissioning before the system is handed over.
