Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a few explanations why your air conditioning won’t start: an overloaded circuit breaker, incorrect thermostat settings, a turned off switch or a full condensate drain pan.
Overloaded Circuit Breaker
Your air conditioner won’t run when you have a tripped breaker.
To determine if one has gotten overloaded, find your home’s main electrical panel. You can find this silver device on the wall in the basement, garage or closet.
- Ensure your hands and feet aren’t wet before you work on the panel or breakers.
- Locate the breaker marked “AC” and make sure it’s in the “on” spot. If it’s triggered, the lever will be in the "off" position.
- Firmly transfer the breaker back to the “on” spot. If it instantly triggers again, don’t reset it and get in touch with us at 561-533-6066 . A switch that keeps flipping could signal your home has electrical trouble.
Incorrect Thermostat Settings
If your thermostat isn’t telling your air conditioner to start, it won’t switch on.
The first step is making sure it’s set to “cool” and not “heat.” Otherwise your air conditioning may not turn on. You might also have hot air coming from vents because the heat is running instead.
If you’re using a regular thermostat:
- Replace the batteries if the readout is blank. If the readout is displaying garbled letters, replace the thermostat.
- Make sure the right program is on the display. If you can’t alter it, reverse it by dropping the temperature and pressing the “hold” button. This will make your AC start if the configuration is incorrect.
- Attempt to set the thermostat 5 degrees lower than the space’s temperature. Your AC won’t start if the thermostat is set the same as the room’s temperature.
Once your thermostat is calibrated accurately, you should begin getting cold air quickly.
If you rely on a smart thermostat, such as one produced by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for assistance. If you still can’t get it to work, call us at 561-533-6066 for help.
Your air conditioner probably has a power-cutting lever around its condenser. This lever is generally in a metal box mounted on your residence. If your unit has recently been fixed, the device may have inadvertently been turned off.
Overflowing Condensate Drain Pan
Condensate drain pans hold the extra liquid your system removes from the air. This pan is located either below or inside your furnace or air handler.
When there’s an obstruction or blocked drain, water can build up and prompt a safety control to turn off your air conditioner.
If your pan involves a PVC pipe or drain, you can clear the additional condensation with a special pan-cleaning tablet. You can purchase these tablets at a home improvement or hardware shop.
If your pan involves a pump, look for the float switch. If the switch is “up” and there’s liquid in the pan, you could need to get a new pump. Call us at 561-533-6066 for assistance.
2. AC Blows Warm Air
If your equipment is on but not delivering cold air, its airflow could be obstructed. Or it might not have sufficient refrigerant.
Your system’s airflow can be decreased by a plugged air filter or dusty condenser.
How to Put in a New Your Air Filter
A filthy filter can lead to a lot of issues, including:
- Lower airflow
- Icy refrigerant lines or evaporator coil
- Intermittent cooling
- Bigger electricity expenses
- Causing your system to wear out more quickly
We suggest installing new flat filters every four weeks, and pleated filters every three months.
If you can’t recall when you last replaced your filter, turn off your unit totally and take out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It could also be found in an attached filter box or wall-mounted return air grille.
Angle the filter up to your light fixture. If you can’t see any light, you need to get a new one.
4 Tips on Cleaning Your Cooling System
Weeds, vegetation and leaves can obstruct your condensing system. This can restrict its airflow, impact its energy efficiency and affect your comfort. Here’s how you can get your unit operating smoothly again.
- Switch off electricity completely at the breaker or outdoor device.
- Clear greenery debris around the unit. Once you’ve gotten rid of larger refuse within a two-foot space, you can use a soft brush or vacuum to carefully clean the equipment’s fins. Bent fins can also hurt performance.
- Use a hose nozzle to slowly clean the fins from inside the equipment. Make sure to avoid getting moisture on the fan motor.
- Turn the power back on.
When cooling equipment doesn’t have sufficient refrigerant, they’ll have to work much harder to remove heat and humidity from your space.
Here are several flags that your unit is leaking refrigerant:
- It takes an extended amount of time to refresh your rooms and you’re regularly turning down the thermostat.
- Air blowing through the ducts isn’t as cold as it should be.
- You’re noticing fizzing or burbling racket when the air conditioning is on.
- Your evaporator coil is iced over as a result of having an issue handling heat.
Suspect your equipment is leaking refrigerant? You need a authorized heating and cooling service professional to take care of the leak and replenish the right level of refrigerant in your system. Reach us at 561-533-6066 for help.
3. AC Not Blowing Enough Air
When it feels like you’re not having ample amounts of cold air, there’s probably a clog or separation inside your air conditioning unit.
- The initial step is examining your air filter. Buy a new one if it’s dusty.
- Make sure the registers are open around your residence.
- If you’re still not experiencing enough cold air, you should have your ductwork checked by a expert like Smyth Air Conditioning Inc. Your ductwork may need to be fixed or relinked in difficult locations like your attic, basement or crawl space.
