Customaire Heating & Cooling: Trusted HVAC Repair Serving Hayward, WI 54843.0

A cracked heat exchanger is a serious safety issue, as it can allow carbon monoxide to leak into your home. Key signs include a strange, metallic smell when the furnace runs, visible soot around the furnace, a change in the flame color from blue to yellow, or excessive moisture on windows. If you notice any of these, turn off your furnace immediately and call us for an urgent inspection to protect your family.

Inconsistent room temperatures are a common frustration in our area and often point to thermostat issues. This could be due to incorrect placement (like in direct sunlight or a drafty hallway), aging components losing calibration, or wiring problems. Our technicians can diagnose the root cause, properly relocate or recalibrate your thermostat, or recommend a modern programmable model for better control and efficiency throughout your Hayward home.
