D& H Heating and Air Conditioning - Waukesha's Experienced HVAC Repair

We often advise Waukesha homeowners with older systems to be proactive. Furnaces over 15 years are more prone to heat exchanger cracks—a serious safety hazard—and lose efficiency, costing you more each winter. A pre-season replacement avoids emergency breakdowns in the cold, ensures your family's safety, and can significantly lower your energy bills with a modern, efficient model.

Key signs include a strange, metallic smell when the furnace runs, visible soot around the furnace, or moisture/rust on the vent pipe. It's dangerous because cracks can allow carbon monoxide—a deadly, odorless gas—to leak into your home's air supply. If you notice any of these signs, turn off your furnace immediately and call us for a safety inspection. We use specialized tools to detect even hairline cracks.

Absolutely. Our comprehensive maintenance service is designed for Wisconsin's harsh seasons. We clean critical components, check for early signs of wear (like stress on the heat exchanger), ensure safe exhaust venting, and optimize efficiency. This yearly tune-up not only helps prevent unexpected failures during a freeze or heatwave but also extends the overall lifespan of your system, protecting your investment.
