R W Freel Heating & Cooling - South Bend's Top-Rated HVAC Services

Inconsistent temperatures often point to a malfunctioning thermostat, a common issue in our area due to age, dust, or calibration drift. Our technicians will test your thermostat's accuracy, check for wiring issues, and ensure it's properly leveled and located away from heat sources. Often, a professional calibration or upgrade to a modern programmable model resolves the problem, improving both comfort and energy efficiency.

Frozen evaporator coils are typically caused by restricted airflow from a dirty air filter or blocked vents, or by low refrigerant levels. In South Bend's humid summers, this problem can quickly stop your cooling. We'll first safely thaw the system, then perform a thorough inspection to identify the root cause—whether it's replacing a filter, cleaning ducts, fixing a blower fan, or sealing a refrigerant leak—to prevent it from happening again.

The best choice depends on the thermostat's age, type, and the extent of the malfunction. For older, non-programmable models causing issues, replacement with a modern smart or programmable thermostat often provides better reliability, precise temperature control, and significant energy savings. For newer models, a repair or recalibration might be all that's needed. We'll provide a clear, honest assessment to help you make the most cost-effective decision for your home.
