Common Questions

What are the most common causes of a frozen evaporator coil in my Greencastle home?

In our local climate, a frozen evaporator coil is often caused by restricted airflow from a dirty air filter, low refrigerant levels due to a leak, or a failing blower motor. We'll diagnose the root cause—whether it's a simple filter change or a more complex repair—to prevent the issue from recurring and protect your system from further damage.

How can I tell if my HVAC system was installed improperly?

Signs of a poor installation include uneven heating or cooling, unusually high energy bills, frequent repairs, excessive noise, and poor indoor air quality. Our team performs comprehensive evaluations of existing systems to identify ductwork issues, incorrect sizing, or faulty component setup, providing solutions to correct these inefficiencies and restore optimal performance.

Why is correct HVAC system sizing so important for Indiana homes?

An oversized or undersized system is a common installation error that leads to comfort problems, short cycling, and wasted energy. We perform precise Manual J load calculations specific to Greencastle's weather patterns and your home's characteristics to ensure your new system is perfectly sized for efficient operation, consistent comfort, and lower utility costs.
