Most gas furnaces last 15 to 20 years. If your Wauwatosa home's furnace is approaching that range, the question isn't whether to replace it — it's whether you replace it on your schedule or your furnace's. Burkhardt Heating, Cooling, Plumbing & Electric has guided Milwaukee County homeowners through furnace replacements for over 60 years.
**Signs Your Furnace Is Due for Replacement**
Age alone is reason to plan ahead. These warning signals indicate replacement is the right move:
- **Frequent repairs:** Two or more service calls in recent years signal escalating wear. When repair costs approach 50% of a new system's price, replacement makes better financial sense. - **Rising heating bills:** An aging furnace at 70% efficiency costs noticeably more to run than a modern 96% AFUE unit. - **Uneven heating:** Rooms consistently too cold or too warm suggest the furnace is struggling — often compounded by failing ductwork. - **Short-cycling or constant running:** Either pattern indicates the system is no longer functioning correctly.
**Efficiency Gains with a Modern Replacement**
Upgrading from an 80% AFUE furnace to a 96% model typically reduces annual heating fuel costs by 20% or more. For homes like those in Wauwatosa's Washington Highlands architect-designed early 20th-century homes alongside the Froedtert-Medical College of Wisconsin campus, the efficiency payback calculation is compelling across virtually every property vintage. Burkhardt installs replacement systems from Lennox, Carrier, Trane, Goodman, and American Standard.
**GreenSky Financing Available**

**Frequently Asked Questions**
**Should I repair or replace my aging furnace?** A useful guideline: multiply the furnace's age by the repair estimate. If the result exceeds $5,000, replacement is usually the better investment — for example, a 16-year-old furnace with a $350 repair estimate equals $5,600. Our technicians give an honest assessment either way.
**How quickly can Burkhardt replace my furnace in Wauwatosa?** Most replacements can be scheduled within a few business days. If your furnace has failed during cold weather, we prioritize emergency replacements. Call 414-206-3049 to discuss your situation.
