Expert Insights
Pro Tips: Central AC Repair in Waltham
Before calling a technician, these checks can save time and help you describe the problem accurately.
Never Ignore Refrigerant Loss
Refrigerant should not deplete unless there is a leak. Topping off without locating and sealing the leak is only a temporary and costly fix.
Verify Thermostat Settings
Confirm the thermostat is set to the correct mode (heat/cool), the target temperature is appropriate, and the battery is fresh.
Inspect Electrical Connections
Corroded or loose wiring causes intermittent failures and is a fire hazard. Always shut off power at the disconnect before any inspection.
