Gas Furnace Installation in Plano, TX
Gas furnace installation in Plano, Texas. We replace 20-year-old units with high-efficiency condensing furnaces, sized by Manual J load calc, with proper venting and gas line checks for older homes.
Replacing 20-Year-Old Furnaces Across Plano
Plano is Collin County's largest and most established suburb, home to about 285,494 people, and a big share of those homes are 20 to 30 years old. That puts a lot of original gas furnaces right at the end of their service life. We replace those tired 80% units with sealed-combustion condensing furnaces, size the new system with a real Manual J load calculation, and handle the PVC venting, condensate drain, and gas line checks that a high-efficiency furnace requires in an older home. If your furnace is acting up, we also do furnace repair in Plano and can tell you honestly whether it's worth fixing.
What We Watch For in Older Plano Furnaces
Furnaces Aging Past 20 Years
Plano's housing stock averages about 25 years old, so a lot of original 80% furnaces are now well past their service life and dropping in efficiency every winter.
We replace with sealed-combustion condensing furnaces that recover the heat older units sent up the flue
Cracked Heat Exchangers
A two-decade-old furnace can develop heat exchanger cracks that leak carbon monoxide. It is the most common reason we condemn an older Plano furnace.
We test for CO and exchanger integrity, and replace unsafe units fast, not patch them
Old Gas Lines & Venting
Older Plano homes often have gas line sizing and venting set up for a low-efficiency furnace, not a modern 95% AFUE condensing unit.
We verify gas line capacity and run proper PVC venting and condensate drainage for condensing furnaces
Right-Sizing the Replacement
The old furnace was often oversized by a builder rule of thumb, which short-cycles and wears parts out faster.
We run a Manual J load calculation so the new furnace is sized to the actual home, not guessed
