Texas Furnace

Texas Furnace is a manufacturer of residential gas furnaces for heating applications in the southern and central United States and other regions where natural gas heating is the standard fuel source. Texas Furnace is a brand of International Comfort Products (ICP), headquartered in Lewisburg, Tennessee, which has designed and manufactured heating and cooling equipment in U.S. and international facilities for more than 70 years. ICP is part of Carrier Global Corporation. Texas Furnace gas furnaces are available in 80% AFUE standard-efficiency and 90% AFUE high-efficiency configurations across the ABA, VSA, and CSA series. HVAC contractors in the southern United States and adjacent markets specify Texas Furnace gas furnaces where ICP-manufactured equipment, regional parts availability, and an established service history are the primary specifying criteria for residential furnace replacement and new construction heating installations.

Texas Furnace Product Lines

ABA Series (80%+ AFUE Gas Furnaces)

The Texas Furnace ABA Series is the standard-efficiency gas furnace line, designed for residential heating applications where 80%+ AFUE meets the local efficiency code minimum and a high-efficiency upgrade is not required. The ABA Series features a computer-designed heat exchanger and burner system that provides quiet, dependable heating performance at the 80%+ AFUE rating. ABA Series furnaces are suited for residential replacement and new construction applications in climate zones where 80% AFUE satisfies the minimum efficiency standard for gas furnaces. Where the Texas Furnace 90% AFUE lines (VSA and CSA Series) are specified for high-efficiency applications, the ABA Series serves the standard-efficiency application where an 80%+ AFUE gas furnace meets the project requirement at a lower first cost.

VSA Series (90% AFUE Gas Furnaces)

The Texas Furnace VSA Series is a 90% AFUE gas furnace line designed for residential heating applications where high-efficiency operation is required by local code, utility incentive programs, or building specifications. The VSA Series delivers 90% AFUE efficiency, meaning 90 percent of the fuel energy input is converted to useful heat delivered to the conditioned space, with the remaining 10 percent exiting as flue gas through the sealed combustion venting system. 90% AFUE furnaces from the Texas Furnace VSA Series use induced draft combustion and secondary heat exchangers that extract additional heat from the combustion gases before venting. VSA Series furnaces require PVC or CPVC sealed combustion venting rather than the B-vent flue used with 80% AFUE ABA Series furnaces.

CSA Series (90% AFUE Gas Furnaces)

The Texas Furnace CSA Series is an additional 90% AFUE gas furnace configuration within the Texas Furnace lineup, providing a 90% AFUE option alongside the VSA Series for residential and light commercial heating applications requiring high-efficiency natural gas heating. The CSA Series is manufactured as part of the International Comfort Products line produced in ICP's U.S. and international manufacturing facilities. As with the VSA Series, CSA Series furnaces use sealed combustion venting through PVC or CPVC flue pipe. The CSA and VSA Series serve the same 90% AFUE application category; consult Texas Furnace product documentation for series-specific differences in capacity range, cabinet width, and staging configuration between the two 90% AFUE lines.

Why Contractors Specify Texas Furnace

HVAC contractors specify Texas Furnace gas furnaces because the brand is manufactured by International Comfort Products, which has produced HVAC equipment for more than 70 years in U.S. and international facilities, providing an established service parts network and equipment history for in-service furnaces. Texas Furnace covers both 80%+ AFUE (ABA Series) and 90% AFUE (VSA and CSA Series) efficiency tiers, allowing contractors to select the appropriate efficiency level for the installation jurisdiction's code requirement without switching manufacturers. ICP's manufacturing under Carrier Global Corporation supports parts commonality and service infrastructure across the ICP brand portfolio. Texas Furnace is positioned for the regional residential market where standard and high-efficiency gas furnace replacement and new construction installations are the primary service mix. Texas Furnace products are available through HVAC supply distributors including SupplyHouse.

How to Choose a Texas Furnace Product

The primary selection variable for a Texas Furnace gas furnace is the required AFUE efficiency level. The Texas Furnace ABA Series (80%+ AFUE) suits installations where 80% AFUE meets the local code minimum and high-efficiency is not required. The VSA Series and CSA Series (both 90% AFUE) suit installations where 90% AFUE is required by local code, utility rebate program qualification, or building specification. Confirm the minimum AFUE requirement for the installation jurisdiction before selecting the Texas Furnace series.

The second variable is furnace heating capacity in BTU/hour. Texas Furnace gas furnaces are available in multiple BTU capacities to match the calculated heating load for the conditioned space. A Manual J heating load calculation determines the required BTU capacity for the installation; do not use rules of thumb such as square footage alone to size a Texas Furnace furnace. Confirm the furnace BTU input and output match the calculated heat loss for the conditioned space.

The third variable is venting configuration. Texas Furnace 80%+ AFUE ABA Series furnaces use B-vent through a vertical flue or through the wall in specific configurations. Texas Furnace 90% AFUE VSA and CSA Series furnaces use sealed PVC or CPVC combustion venting that can be run horizontally through the wall. Confirm the available venting route at the installation location before selecting between the 80% and 90% AFUE Texas Furnace series, as the venting type affects both the installation cost and the feasibility of the selected furnace at that location.

FAQs

Who manufactures Texas Furnace gas furnaces?

Texas Furnace gas furnaces are manufactured by International Comfort Products (ICP), headquartered in Lewisburg, Tennessee. ICP has designed and manufactured HVAC equipment for more than 70 years in U.S. and international facilities. ICP is part of Carrier Global Corporation.

What warranty does Texas Furnace offer on its gas furnaces?

Texas Furnace gas furnace warranty terms are available through the International Comfort Products documentation at icpusa.com. Warranty coverage on Texas Furnace furnaces varies by model and registration status; confirm the applicable warranty with an authorized Texas Furnace dealer or distributor at the time of installation.

What is the difference between the Texas Furnace ABA Series and the VSA Series?

The difference between the Texas Furnace ABA Series and VSA Series is the AFUE efficiency rating and venting type. The ABA Series is an 80%+ AFUE standard-efficiency furnace using B-vent flue. The VSA Series is a 90% AFUE high-efficiency furnace using sealed PVC or CPVC combustion venting. The 90% AFUE VSA Series converts a greater percentage of fuel energy to heat, resulting in lower fuel use per heating season compared to the ABA Series.

What venting type does the Texas Furnace VSA Series 90% AFUE furnace require?

The Texas Furnace VSA Series 90% AFUE gas furnaces use sealed combustion venting through PVC or CPVC flue pipe, which can be routed horizontally through the exterior wall or vertically through the roof. Sealed combustion venting differs from the B-vent used with the Texas Furnace ABA Series 80% AFUE furnaces. Confirm the venting route availability at the installation location before specifying a VSA or CSA Series furnace, as sealed PVC venting requires a different rough-in than B-vent.

What heating capacities are available in Texas Furnace gas furnaces?

Texas Furnace gas furnaces are available in multiple BTU heating capacities across the ABA, VSA, and CSA series to match the calculated heating load for the conditioned space. Furnace BTU capacity should be selected based on a Manual J heating load calculation for the specific building and climate zone, not on rules of thumb. Consult Texas Furnace product documentation at texasfurnace.com or icpusa.com for the specific BTU capacity range available in each series.

Is the Texas Furnace CSA Series different from the VSA Series?

Both the Texas Furnace CSA Series and VSA Series are 90% AFUE gas furnaces using sealed PVC or CPVC combustion venting, serving the same high-efficiency residential application. Differences between the CSA and VSA Series may include BTU capacity range, cabinet width, blower configuration, or staging type. Consult Texas Furnace product documentation at texasfurnace.com for the specific series-level differences before selecting between the CSA and VSA Series for a given installation.
