Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a couple of explanations why your air conditioner won’t run: an overloaded circuit breaker, incorrect thermostat settings, a shut off switch or a full condensate drain pan.
Triggered Circuit Breaker
Your air conditioner won’t work when you have an overloaded breaker.
To see if one has gotten overloaded, find your residence’s main electrical panel. You can locate this gray box on the wall in the basement, garage or closet.
- Confirm your hands and feet are dry before you check the panel or breakers.
- Find the breaker identified “AC” and ensure it’s in the “on” location. If it’s triggered, the breaker will be in the "off" position.
- Steadily move the breaker back to the “on” location. If it immediately flips again, don’t touch it and contact us at 614-871-4144. A switch that keeps tripping could indicate your home has an electrical issue.
Inaccurate Thermostat Settings
If your thermostat isn’t telling your system to run, it won’t activate.
The key point is making sure it’s switched to “cool” and not “heat.” Otherwise your air conditioning may not switch on. You could also receive warm air coming from vents being the furnace is on instead.
If you rely on a digital thermostat:
- Swap out the batteries if the screen is empty. If the monitor is showing garbled letters, replace the thermostat.
- Ensure the proper option is on the display. If you can’t change it, reverse it by dropping the temperature and pressing the “hold” button. This will cause your AC to run if the configuration is incorrect.
- Attempt to set the thermostat 5 degrees below the house’s temperature. Your AC won’t work if the thermostat matches the space’s temperature.
Once your thermostat is adjusted properly, you should receive cool air quickly.
If you’re using a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for troubleshooting. If you’re still having problems, call us at 614-871-4144 for support.
Your cooling equipment probably has a shut-off switch by its outdoor unit. This device is commonly in a metal box hung on your home. If your equipment has recently been repaired, the switch may have accidentally been turned off.
Clogged Condensate Drain Pan
Condensate drain pans keep the surplus liquid your system removes from the air. This pan can be situated either below or within your furnace or air handler.
When there’s a blockage or clogged drain, water can become concentrated and initiate a safety setting to switch off your equipment.
If your pan involves a PVC pipe or drain, you can get rid of the extra water with a formulated pan-cleaning tab. You can get these tablets at a home improvement or hardware retailer.
If your pan involves a pump, locate the float switch. If the mechanism is “up” and there’s liquid in the pan, you may need to replace the pump. Contact us at 614-871-4144 for help.
2. AC Blows Warm Air
If your equipment is working but not cooling, its airflow may be clogged. Or it may not have adequate refrigerant.
Your unit’s airflow can be limited by a plugged air filter or dirty condenser.
How to Replace Your Air Filter
A dusty filter can lead to numerous troubles, including:
- Lower comfort
- Frozen refrigerant lines or evaporator coil
- Intermittent cooling
- Bigger energy bills
- Causing your system to stop working sooner
We recommend replacing flat filters monthly, and pleated filters every three months.
If you can’t remember when you last replaced your filter, switch off your equipment totally and pull out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It might also be located in an attached filter box or wall-mounted return air grille.
Tilt the filter up to your light fixture. If you can’t see any light, you should replace it.
How to Clean Your Air Conditioning System
Weeds, grass and shrubbery can obstruct your condensing unit. This could reduce its airflow, impact its energy efficiency and change your comfort. Here’s how you can get your unit running well again.
- Switch off the electrical current fully at the breaker or outside switch.
- Get rid of plant debris around the AC. Once you’ve gotten rid of bigger refuse within a two-foot space, you can use a fine-bristled brush or vacuum to carefully clean the condenser fins. Distorted fins can also affect performance.
- Use a hose nozzle to gingerly take off dirt on the fins from inside the system. Be careful to avoid getting liquid on the fan motor.
- Turn the power back on.
Low Refrigerant Levels
When air conditioning equipment doesn’t have enough refrigerant, they’ll have difficulty removing heat and humidity from your home.
Here are a few flags that your equipment is losing refrigerant:
- It takes a long time to cool your space and you’re regularly lowering the thermostat.
- Air blowing through the ducts isn’t as cold as it should be.
- You’re noticing fizzing or burbling racket when cooling is on.
- Your evaporator coil is frozen on account of having trouble taking on heat.
Think your equipment is leaking refrigerant? You need a qualified heating and cooling service professional to repair the leak and replenish the correct amount of refrigerant in your system. Get in touch with us at 614-871-4144 for help.
3. AC Not Blowing Enough Air
When it feels like you’re not receiving adequate amounts of cool air, there’s potentially a blockage or separation somewhere in your AC equipment.
- The initial stage is checking your air filter. Replace it if it’s dusty.
- Make sure the vents are open around your rooms.
- If you’re still not receiving adequate chilly air, you should have your ducts examined by a specialist like Air Quality Solutions. Your ductwork could need to be serviced or reconnected in difficult spots like your attic, basement or crawl space.
