It is an unusually hot day in New England, and all of a sudden, your AC system refuses to turn on. How do you get back the cool, comfortable air that helped you beat the heat? Most of the causes of a malfunctioning AC system do not require the services of an HVAC contractor. However, when you cannot fix the problem, calling our team of HVAC specialists ensures your AC system returns to delivering cool comfort.
Here are six common reasons why your AC won’t turn on.
Broken Down Motor
As an especially common problem in older units, a motor that does not spin the fan and/or emits loud noises when you try to start the AC system has probably seen its better days. Although this is the last type of AC problem you want to have, it often is the first thing we check during a repair call.
Improper Setting of the Thermostat
Some AC system issues do not require the professional expertise of a Massachusetts licensed HVAC contractor. Check the thermostat setting before you call us for repair work. Ensure you have switched the switch from “Heat” to “Cool.” There typically is a significant lapse in time between when New Englanders move from heating a home to cooling it. We have customers that forget to make the switch.
Circuit Breakers are Off
At the end of last year’s AC season, you might have turned off a circuit breaker. Many Boston area homeowners turn off the outdoor power supply when Old Man Winter starts to churn up the North Atlantic. Check the breaker located on the panel box to make sure it is on.
Air Filter Clogged
Running an AC system for a prolonged period can accumulate dirt and debris in the air filter. Too much dirt and debris clogs the air filter, which restricts the flow of air through the system. When the air filter is clean, it encourages water droplets to fall in the condensation tray. However, a dirty air filter freezes water droplets to clog the coils with a thick layer of ice.
Check the Wiring
Do lights flicker on and off inside your home? Do one or more electric appliances perform at less than optimal efficiency. Electrical issues often stem from wiring problems, which can prevent an AC system from turning on. Sometimes, it is just a poor connection, while other times you might need to complete a significant rewiring project.
Get Help from a Highly Rated HVAC Contractor
We recommend that our customers conduct a thorough inspection of their AC systems at the start of spring. You probably do not need to turn on the system in early March, but you want to be prepared for the inevitable surge of hot air come June, July, and August. If you detect an issue with the motor, call our team of HVAC experts to discover the cause of the malfunction. Other issues like a circuit breaker that just needs to be turned on can be handled from your end.
