Frequently Asked Questions About AC and Heating
Common causes include low refrigerant levels (indicating a leak), a failing compressor, a clogged expansion valve, or electrical issues. Our technicians use specialized equipment to diagnose the specific problem. Simply adding refrigerant without finding and fixing leaks is a temporary solution that won't last.
Most manufacturers recommend AC system inspection annually, ideally before summer. Regular service identifies minor issues before they become expensive failures and ensures your system runs efficiently. If you notice reduced cooling performance or unusual noises, schedule service immediately rather than waiting.
A heater blowing cold air typically indicates low coolant levels, a failing thermostat, a clogged heater core, or problems with blend doors that control air temperature. In Massachusetts winters, a working heater isn't just comfort, it's essential for safety and windshield defogging.
While DIY recharge kits exist, professional service is recommended. Overcharging can damage your compressor, and adding refrigerant without finding the leak wastes money. Our technicians evacuate the system properly, check for leaks, and recharge to exact specifications for optimal performance and longevity.
