Granger Heat & Air | Qualified HVAC Services in Mishawaka, IN

Common signs in Mishawaka homes include weak or no airflow from vents, unusual humming or screeching noises from the furnace, the system frequently overheating and shutting off, or a complete lack of heating or cooling. Since a failing blower motor can strain other components, it's best to have our technicians diagnose it promptly to prevent a total breakdown.

This is often a symptom of a faulty reversing valve, a common issue we see in Mishawaka. This valve is responsible for switching your heat pump between heating and cooling modes. When it gets stuck due to wear, debris, or electrical failure, the system locks into one function. Our experts can test the valve and perform the precise repair to restore your system's full-year functionality.

First, check your home's circuit breaker and the system's power switch near the indoor unit—a simple trip is a frequent culprit. If power is confirmed, listen for unusual noises and note any error codes on the thermostat. For safety and to prevent further damage, especially with complex components like motors and valves, we recommend calling Granger Heat & Air. Our local team can provide guidance and schedule a swift, professional diagnosis.
