Furnace Installation & Replacement FAQs 

What AFUE efficiency rating is recommended for Southeastern Wisconsin winters?

Annual Fuel Utilization Efficiency (AFUE) measures how efficiently a unit converts fuel into heat. While standard models start at 80% AFUE, we strongly recommend high-efficiency condensing furnaces rated at 95% to 98% AFUE for Waukesha homes. These units feature sealed combustion and PVC direct-venting, converting up to 98 cents of every energy dollar into usable heat and significantly lowering gas heating bills during prolonged sub-zero cold snaps.

How do I know if my furnace needs to be replaced or just repaired?

If your furnace is over 15 to 20 years old, requires frequent repairs, or struggles to maintain comfortable indoor temperatures during peak winter, replacement is usually the smarter financial investment. Additionally, cracked heat exchangers, often caused by age and constant thermal stress, pose a severe carbon monoxide safety risk that necessitates an immediate system replacement.
