Section 1: Why AC Installation in Hanover Demands Expert Attention

The Hanover Climate Challenge

• Summer Highs: Frequently hit mid to high 80s°F

• Humidity: Consistently above 70%, increasing indoor heat perception

• Utility Rates: Massachusetts ranks among the top 10 states for energy costs

Because of these factors, choosing the wrong unit—or hiring an inexperienced installer—can lead to:

• Poor airflow

• Excessive humidity indoors

• Soaring utility bills

• Premature system failure
