Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a couple of causes why your air conditioner won’t work: an overloaded circuit breaker, incorrect thermostat settings, a switched off switch or an overfull condensate drain pan.
Triggered Circuit Breaker
Your AC won’t run when you have a blown breaker.
To check if one has blown, go to your home’s main electrical panel. You can locate this metallic device on the wall in the basement, garage or closet.
- Make sure your hands and feet are dry before you check the panel or breakers.
- Locate the breaker labeled “AC” and make sure it’s in the “on” location. If it’s tripped, the lever will be in the middle or “off” spot.
- Steadily shift the breaker back to the “on” position. If it instantaneously triggers again, don’t touch it and call us at 208-621-0129. A fuse that keeps tripping might mean your house has electrical trouble.
Inaccurate Thermostat Settings
If your thermostat isn’t giving a sign to your system to work, it won’t turn on.
The key part is making sure it’s on “cool” and not “heat.” Otherwise your air conditioner will probably not turn on. Or you could get hot air moving from vents since the heat is on instead.
If you rely on a traditional thermostat:
- Replace the batteries if the monitor is clear. If the monitor is showing jumbled numbers, get a new thermostat.
- Ensure the right setting is showing. If you can’t change it, reverse it by dropping the temperature and pushing the “hold” button. This will cause your AC to run if the configuration is wrong.
- Attempt to set the thermostat 5 degrees below the space’s temperature. Your AC won’t start if the thermostat matches the room’s temperature.
Once your thermostat is calibrated correctly, you should start getting cool air quickly.
If you rely on a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for help. If it still won’t work, contact us at 208-621-0129 for assistance.
Your air conditioner usually has a power-cutting lever by its outside unit. This device is generally in a metal box hung on your house. If your AC has recently been worked on, the lever may have unintentionally been positioned in the “off” position.
Blocked Condensate Drain Pan
Condensate drain pans keep the extra liquid your air conditioner 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 control to stop your unit.
If your pan involves a PVC pipe or drain, you can drain the extra water with a formulated pan-cleaning tablet. You can buy these capsules at a home improvement or hardware retailer.
If your pan includes a pump, locate the float switch. If the lever is “up” and there’s liquid in the pan, you could need to get a new pump. Call us at 208-621-0129 for help.
2. AC Blows Warm Air
If your air conditioner is running but not delivering cold air, its airflow could be clogged. Or it may not have sufficient refrigerant.
Your equipment’s airflow can be reduced by a plugged air filter or dirty condenser.
How to Put in a New Your Air Filter
A dirty filter can create many problems, such as:
- Limited airflow
- Frozen refrigerant lines or evaporator coil
- Uneven cooling
- Bigger electricity bills
- Making your system wear out faster
We suggest replacing flat filters once a month, and accordion filters every three months.
If you can’t recall when you last replaced yours, 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 might also be situated in an adjoining filter box or wall-mounted return air grille.
Angle the filter up to the sunshine. If you see a lot of dust, you certainly should buy a new filter.
5 Steps to Cleaning Your Cooling Equipment
Weeds, plants and leaves can get in the way of your condensing system. This could reduce its airflow, impact its energy efficiency and affect your comfort. Here’s a method you can follow to get your unit operating properly again.
- Turn off power completely at the breaker or outside device.
- Remove vegetation debris around the equipment. Once you’ve removed bigger refuse within a two-foot range, you can use a soft brush or vacuum to carefully remove dust from the unit’s fins. Deformed fins can also affect capability, so you can attempt to adjust them with a blunt knife.
- Remove the top of your air conditioner and take out any leaves or sticks that has accumulated. Then wipe down the condenser fan with a damp cloth.
- Use a hose nozzle to gingerly take off dirt on the fins from inside the system. Don’t get liquid on the fan motor.
- Install the top again and restore the power.
When AC systems don’t have ample refrigerant, they’ll have difficulty removing heat and humidity from your space.
Here are a couple of symptoms that your equipment is leaking refrigerant:
- It takes an extended amount of time to cool your house and you’re regularly turning down the thermostat.
- Air coming through the registers isn’t as cold as it should be.
- You’re hearing whistling or burbling racket when cooling works.
- Your evaporator coil is icy because it’s having an issue taking on heat.
Worried your system is leaking refrigerant? You need a certified heating and cooling service professional to take care of the leak and refill the correct amount of refrigerant in your unit. Get in touch with us at 208-621-0129 for assistance.
3. AC Not Blowing Enough Air
When it appears like you’re not receiving adequate amounts of cold air, there’s usually an obstruction or detachment somewhere in your air conditioning unit.
- The beginning place is looking at your air filter. Get a new one if it’s dirty.
- Then check the vents are free throughout your home.
- If you’re still not receiving ample chilled air, you should have your ducts examined by a specialist like Vogts Heating & Air. Your ducts might need to be fixed or hooked up again in tricky spots like your attic, basement or crawl space.
