AC Replacement Services That Fit Dedham Homes

When Should You Consider Replacing Your AC Unit?

Deciding whether to repair or invest in a full ac replacement often comes down to a few telltale signs:

• Your system is 10–15 years old
• Frequent breakdowns or costly repairs
• Rising utility bills due to inefficient cooling
• Uneven temperatures between rooms
• Use of outdated refrigerants like R-22

Given Dedham's fluctuating climate and older electrical infrastructure in some neighborhoods, running inefficient systems can greatly impact your comfort and wallet.

• Eco-Friendly Refrigerants: Modern units use R-410A, which doesn’t deplete the ozone layer
• Humidity Control: Key for preventing mold/mildew in older homes with basements or minimal ventilation
• Zoned Cooling Options: Perfect for Colonial-style homes or multi-story layouts
