Is Your AC Ignoring You?

Common Issues Why Your AC is Not Turning On

Hey there, North Hollywood neighbors! It’s Mor Air Inc., your friendly neighborhood HVAC experts. We know how frustrating it can be when your air conditioner decides to take a vacation on the hottest day of the year. But don’t sweat it—we’re here to help you understand why your AC won’t turn on and what you can do about it. Let’s dive in and troubleshoot this together!

1. Thermostat Issues

First things first, let’s talk about thermostats. Your thermostat is like the brain of your AC system. If it’s not working right, nothing else will either.

  • Checking Thermostat Settings: Ensure your thermostat is set to “cool” and the temperature is a few degrees lower than the room temperature. If this doesn’t solve the issue, the temperature sensor in the thermostat may be inaccurate.
  • Temperature Sensor Problems: Sometimes, the thermostat’s sensor can be off, giving incorrect readings. If your thermostat thinks your home is already cool, it won’t signal the AC to turn on.
  • Thermostat Replacement: If your thermostat is old or malfunctioning, it might be time for an upgrade. A modern, programmable thermostat can make a world of difference in maintaining your home’s comfort. Always consult with an expert to help determine the best choice for your residence.

2. Power Supply Problems

Next up, let’s ensure your AC is getting the power it needs to run.

  • Circuit Breaker Check: If the breaker for your AC unit has tripped, there could be a deeper electrical issue. Contact a professional to inspect and resolve this safely.
  • Indoor Shutoff Switch: This switch, often located near your furnace, might look like a regular light switch. Make sure it’s in the “on” position. Sometimes, it gets flipped off accidentally.
  • Outdoor Shutoff Switch: Check the switch near your outdoor AC unit. If it was turned off during maintenance and not flipped back on, your AC won’t start.

3. Airflow Obstructions

Airflow is crucial for your AC to function properly. Let’s see if something is blocking that flow.

  • Dirty Air Filters: A clogged filter can block airflow, causing your AC to freeze up and stop working. Regular filter changes are key to a happy AC system. Consult with an HVAC professional to maintain optimal airflow.
  • Ice Buildup on AC Unit: If you see ice on your AC unit, it needs to defrost before it can work again. Contact a professional if you notice ice buildup to prevent further damage.
  • Clogged Condensate Drain: If the condensate drain is blocked, your AC might shut off as a safety measure. Have a technician clean the drain line and ensure everything is functioning correctly.

4. Component Failures

Sometimes, the problem lies within the components of your AC unit itself.

  • Malfunctioning Capacitor: The capacitor gives your AC the initial jolt of energy it needs to start up. If it’s faulty, your AC might struggle to turn on or make clicking noises.
  • Damaged Motor: A grinding noise when you try to start your AC often points to a motor issue. A damaged motor can’t circulate the air, making your AC ineffective. Professional inspection and AC repair are necessary.

5. Refrigerant Issues

Refrigerant is the lifeblood of your AC system, cooling the air that circulates through your home.

  • Low Refrigerant Levels: If your AC is low on refrigerant, it won’t be able to cool your home properly. This usually indicates a leak, which needs to be addressed by a professional.
  • Refrigerant Leaks: Signs of a leak include ice on the evaporator coils and hissing sounds. A leak not only reduces efficiency but can also damage your AC unit if not fixed. Always call a licensed technician for refrigerant issues.

6. AC Age and Size

Sometimes, the age or size of your AC unit can be the root cause of the problem.

  • End of Lifespan Indicators: If your AC is over a decade old, it might be nearing the end of its life. Frequent breakdowns, increased energy bills, and reduced cooling capacity are signs it’s time for a replacement. Consult with an expert to evaluate and replace your unit.
  • Incorrectly Sized AC Unit: If your AC is too large or too small for your home, it will struggle to maintain a comfortable temperature. An improperly sized unit will cycle on and off frequently or run continuously, leading to wear and tear. A professional can help determine the correct size for your home.
