Zimmerman Heating: Expert HVAC Services Serving New Ulm, MN 56073

Absolutely. In our Minnesota climate, leaky ductwork in attics or crawlspaces is a common culprit for uneven heating and rising bills. Heated air escapes before it reaches your rooms, forcing your system to work harder. Zimmerman Heating performs thorough duct inspections using specialized tools to locate leaks, followed by professional sealing to restore efficiency and improve comfort throughout your home.

Not always. Often, a thermostat malfunction is due to calibration issues, wiring problems, or location (like being in direct sunlight or a drafty hallway). Our technicians first diagnose the root cause—whether it's the thermostat itself, the wiring, or a signal issue with your HVAC system. Many times, a repair or recalibration is all that's needed, saving you the cost of a premature replacement.

Key signs include frequent, short cycling (the furnace turns on and off rapidly), some rooms being much colder than others, the furnace running constantly but not reaching the set temperature, and a noticeable increase in heating costs. These symptoms often point to a thermostat sending incorrect signals or leaky ducts losing conditioned air. A professional assessment from our team can pinpoint the exact issue.
