Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several explanations why your central AC system won’t run: a triggered circuit breaker, incorrect thermostat settings, a switched off switch or a full condensate drain pan.
Overloaded Circuit Breaker
Your air conditioning won’t run when you have a blown breaker.
To check if one has gotten overloaded, locate your residence’s main electrical panel. You can find this silver box on the wall in the basement, garage or closet.
- Make sure your hands and feet are free of moisture before you work on the panel or breakers.
- Find the breaker identified “AC” and ensure it’s in the “on” location. If it’s overloaded, the lever will be in the "off" position.
- Firmly shift the breaker back to the “on” location. If it instantly triggers again, don’t reset it and reach us at 209-257-3156. A switch that keeps flipping may signal your house has an electrical issue.
Wrong Thermostat Settings
If your thermostat isn’t giving a sign to your system to start, it won’t switch on.
The first part is ensuring it’s switched to “cool” and not “heat.” Otherwise your air conditioner might not turn on. You may also get warm air moving from vents being the furnace is running instead.
If you have a regular thermostat:
- Replace the batteries if the monitor is clear. If the screen is presenting jumbled letters, get a new thermostat.
- Check the proper program is displaying. If you can’t update it, cancel it by dropping the temperature and pressing the “hold” button. This will cause your AC to run if the configuration is not right.
- Try setting the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat is set the same as the room’s temperature.
Once your thermostat is set accurately, you should start getting refreshing air promptly.
If you have a smart thermostat, like one manufactured by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for assistance. If it still won’t work, reach us at 209-257-3156 for assistance.
Your cooling equipment probably has a shut-down lever by its outdoor unit. This device is commonly in a metal box hung on your residence. If your unit has recently been serviced, the device may have accidentally been turned off.
Clogged Condensate Drain Pan
Condensate drain pans hold the surplus condensation your equipment pulls from the air. This pan can be found either under or in your furnace or air handler.
When there’s a clog or blocked drain, water can accumulate and trigger a safety feature to turn off your system.
If your pan includes a PVC pipe or drain, you can get rid of the extra water with a formulated pan-cleaning capsule. You can buy these tabs at a home improvement or hardware store.
If your pan includes a pump, look for the float switch. If the lever is “up” and there’s liquid in the pan, you may need to replace the pump. Call us at 209-257-3156 for help.
2. AC Blows Warm Air
If your air conditioner is on but not delivering cold air, its airflow could be congested. Or it might not have sufficient refrigerant.
Your equipment’s airflow can be restricted by a clogged air filter or dirty condenser.
How to Change Your Air Filter
A filthy filter can create countless troubles, like:
- Limited comfort
- Frozen refrigerant lines or evaporator coil
- Inconsistent cooling
- Increased cooling expenses
- Causing your system to wear out faster
We suggest changing flat filters once a month, and pleated filters every three months.
If you can’t recall when you last replaced your filter, switch off your unit totally and pull out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It could also be located in a connected filter box or wall-mounted return air grille.
Angle the filter up to your light fixture. If you see a lot of dust, you should replace it.
How to Clean Your AC Equipment
Brush, plants and shrubbery can get in the way of your condensing system. This can reduce its airflow, make it less energy efficient and affect your comfort. Here’s how you can get your system running properly again.
- Shut off power completely at the breaker or outdoor switch.
- Clear plant rubbish around the equipment. Once you’ve cleared all the refuse within a two-foot radius, you can use a paint brush or vacuum to gingerly remove dirt from the condenser fins. Warped fins can also impact effectiveness.
- Use a hose nozzle to carefully take off dirt on the fins from inside the unit. Be careful to avoid getting liquid on the fan motor.
- Restore the power.
When cooling units don’t have enough refrigerant, they’ll struggle to remove heat and humidity from your home.
Here are a few indications that your equipment is losing refrigerant:
- It takes too long to refresh your rooms and you’re constantly turning down the thermostat.
- Air blowing through the registers isn’t as cold as it should be.
- You’re noticing whistling or gurgling noises when the air conditioning works.
- Your evaporator coil is icy on account of having an issue taking on warmth.
Think your system is seeping refrigerant? You need a qualified heating and cooling service specialist to fix the leak and replenish the correct level of refrigerant in your unit. Get in touch with us at 209-257-3156 for support.
3. AC Not Blowing Enough Air
When it seems like you’re not getting ample amounts of cool air, there’s potentially a clog or detachment inside your AC equipment.
- The beginning stage is looking at your air filter. Replace it if it’s dusty.
- Make sure the ductwork is open around your house.
- If you’re still not experiencing ample cold air, you should have your ductwork inspected by a expert like Tokay Heating and Air Conditioning. Your ductwork may need to be repaired or relinked in limited space locations like your attic, basement or crawl space.
