A contractor quoting a furnace installation in Refugio County is not sizing for a climate that hammers equipment year-round. 38 severe weather events were recorded in Refugio County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing operating condition, which shifts where the installation decisions matter: duct layout, equipment sizing for the structure, and the quality of the setup itself carry more weight here than building in headroom for a relentless weather load. A homeowner replacing an old furnace should expect the contractor to focus on the house first.
Ductwork laid down for an older furnace was sized for that furnace, and swapping the unit without addressing what feeds it can leave a new system undersupplied and inefficient from the first day it runs. Half the homes in Refugio County, Texas were built in 1973 or earlier (2020-2024 ACS 5-year). That means a contractor quoting a furnace installation here is evaluating the duct runs and any electrical upgrades the new equipment demands before the unit itself gets selected. A house whose distribution system matches the new load gets full performance; one that does not will need the ductwork brought along with the replacement.
What Gets Installed With a New Furnace
The furnace itself sits in a utility closet, basement, or dedicated mechanical room and is the heart of the system. It houses the burners, the heat exchanger, and the blower that pushes conditioned air into the home. A new installation also includes the flue or venting pipe, which runs from the unit to an exterior wall or roofline and carries combustion exhaust out of the house.
The air handler components built into the furnace cabinet work alongside the evaporator coil, which a contractor mounts directly above or beside the unit to handle cooling when the system is paired with central air. The thermostat goes on an interior wall and is the control point for the whole system. Refrigerant lines, if present, run between the coil and any outdoor cooling equipment.
The drawing shows a representative layout, and a licensed contractor determines exactly what applies to your home's configuration.
