Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a couple of reasons why your air conditioner won’t work: a blown circuit breaker, wrong thermostat settings, a shut off switch or an overfull condensate drain pan.
Overloaded Circuit Breaker
Your air conditioner won’t run when you have a tripped breaker.
To see if one has tripped, find your home’s main electrical panel. You can locate this metallic device on the wall in the basement, garage or closet.
- Ensure your hands and feet aren’t wet before you touch the panel or breakers.
- Look for the breaker identified “AC” and ensure it’s in the “on” position. If it’s triggered, the switch will be in the "off" position.
- Steadily move the breaker back to the “on” location. If it immediately flips again, don’t reset it and reach us at 815-410-1231. A switch that keeps tripping could indicate your house has an electrical problem.
Wrong Thermostat Settings
If your thermostat isn’t signaling your system to start, it won’t switch on.
The most important step is ensuring it’s on “cool” and not “heat.” Otherwise your AC will probably not switch on. You might also receive heated air coming from vents since the furnace is on instead.
If you rely on a traditional thermostat:
- Put in new batteries if the screen is blank. If the monitor is presenting jumbled numbers, get a new thermostat.
- Ensure the right option is on the display. If you can’t change it, reverse it by dropping the temperature and pressing the “hold” button. This will force your AC to work if scheduling is incorrect.
- Test setting the thermostat 5 degrees cooler than the room’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is adjusted accurately, you should start getting chilled air promptly.
If you’re using a smart thermostat, such as one made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for troubleshooting. If you’re still having problems, call us at 815-410-1231 for help.
Your cooling equipment probably has a shut-down switch around its outdoor unit. This lever is generally in a metal box attached to your house. If your equipment has recently been repaired, the device may have inadvertently been turned off.
Clogged Condensate Drain Pan
Condensate drain pans catch the surplus condensation your AC takes out of the air. This pan can be situated either beneath or within your furnace or air handler.
When there’s a clog or blocked drain, water can build up and trigger a safety feature to switch off your system.
If your pan has a PVC pipe or drain, you can drain the surplus water with a custom pan-cleaning tablet. You can purchase these tablets at a home improvement or hardware store.
If your pan involves a pump, find the float switch. If the mechanism is “up” and there’s moisture in the pan, you could need to replace the pump. Contact us at 815-410-1231 for support.
2. AC Blows Warm Air
If your AC is running but not cooling, its airflow could be congested. Or it may not have sufficient refrigerant.
Your system’s airflow can be limited by a clogged air filter or dirty condenser.
How to Change Your Air Filter
A dusty filter can cause countless troubles, such as:
- Limited comfort
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Bigger electricity expenses
- Causing your system to break down more quickly
We propose replacing 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 fully and take out the filter. You can find the filter in your furnace or air pump’s blower compartment. It might also be located in a connected filter holder 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 Cooling Unit
Brush, vegetation and sticks can obstruct your condensing system. This may restrict its airflow, impact its energy efficiency and change your comfort. Here’s a way you can get your system running properly again.
- Switch off electricity fully at the breaker or outdoor switch.
- Clear greenery rubbish around the AC. Once you’ve gotten rid of bigger refuse within a two-foot radius, you can use a paint brush or vacuum to slowly clean the equipment’s fins. Kinked fins can also impact performance.
- Use a hose nozzle to carefully clean the fins from inside the unit. Don’t get water on the fan motor.
- Restore the power.
When cooling systems don’t have adequate refrigerant, they’ll have difficulty removing heat and humidity from your home.
Here are a few signs that your equipment is leaking refrigerant:
- It takes a long time to cool your residence and you’re continually lowering the thermostat.
- Air coming through the ducts isn’t as chilled as it should be.
- You’re hearing fizzing or bubbling racket when the AC is on.
- Your evaporator coil is iced over on account of having an issue absorbing warmth.
Think your system is losing refrigerant? You need a authorized heating and cooling service professional to fix the leak and refill the correct measurement of refrigerant in your equipment. Get in touch with us at 815-410-1231 for support.
3. AC Not Blowing Enough Air
When it seems like you’re not getting enough cold air, there’s possibly a blockage or disconnection within your AC system.
- The first stage is examining your air filter. Buy a new one if it’s dusty.
- Make sure the vents are open across your house.
- If you’re still not experiencing adequate cold air, you should have your ductwork examined by a expert like PWA Heating & Cooling Inc. Your ductwork could need to be fixed or hooked up again in difficult locations like your attic, basement or crawl space.
