Affordable and Effective Air Conditioner Repair Service

As a leading provider of air conditioner repair service in Westwood MA, SumZero focuses on resolving problems that matter most to local homeowners—without up-selling or unnecessary upgrades.

Diagnosing Low Cooling Performance

If your system runs all day but still can’t keep the house cool, we’ll assess:

• Dirty or clogged evaporator coils
• Frozen lines due to low refrigerant levels
• Improperly-sized units for your square footage
• Duct leakage causing loss of cold air

Addressing these cooling issues early can prevent more serious damage and reduce your long-term energy costs.

Fixing Noisy Operation

An AC system that rattles or screeches is more than annoying—it’s potentially harmful. We fix:

• Worn bearings
• Bent or broken fan blades

Electrical and Thermostat Repairs

Modern thermostats are powerful but need occasional recalibration or replacement. Our services include:
