Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several reasons why your AC equipment won’t start: an overloaded circuit breaker, incorrect thermostat settings, a turned off switch or an overfull condensate drain pan.
Blown Circuit Breaker
Your air conditioning won’t start when you have a tripped breaker.
To find out if one has blown, find your residence’s main electrical panel. You can find this metallic box on the wall in the basement, garage or closet.
- Ensure your hands and feet aren’t wet before you check the panel or breakers.
- Locate the breaker labeled “AC” and make sure it’s in the “on” spot. If it’s overloaded, the breaker will be in the middle or “off” position.
- Steadily move the switch back to the “on” spot. If it immediately flips again, don’t touch it and reach us at 816-379-3918. A fuse that keeps turning off may indicate your house has an electrical issue.
Incorrect Thermostat Settings
If your thermostat isn’t telling your air conditioner to work, it won’t switch on.
The key point is ensuring it’s on “cool” and not “heat.” Otherwise your air conditioner may not start running. Or you may have heated air coming from vents because the heat is on instead.
If you rely on a digital thermostat:
- Replace the batteries if the readout is empty. If the monitor is showing scrambled characters, get a new thermostat.
- Check the right program is on the display. If you can’t update it, cancel it by decreasing the temperature and pressing the “hold” button. This will force your AC to work if programming is not right.
- Attempt to set the thermostat 5 degrees below the space’s temperature. Your AC won’t cool if the thermostat matches the house’s temperature.
Once your thermostat is adjusted properly, you should begin getting refreshing air fast.
If you rely on a smart thermostat, like one made by Nest, Ecobee, Lux, Honeywell or Bosch, look at the manufacturer’s website for assistance. If it still won’t work, call us at 816-379-3918 for help.
Your cooling equipment usually has a shut-off lever by its condenser. This lever is generally in a metal box mounted on your house. If your equipment has recently been tuned up, the switch may have accidentally been placed in the “off” location.
Blocked Condensate Drain Pan
Condensate drain pans keep the additional water your air conditioner removes from the air. This pan can be positioned either beneath or in your furnace or air handler.
When there’s an obstruction or backed up drain, water can become concentrated and initiate a safety setting to turn off your equipment.
If your pan has a PVC pipe or drain, you can get rid of the additional liquid with a special pan-cleaning capsule. You can get these capsules at a home improvement or hardware store.
If your pan includes a pump, find the float switch. If the switch is “up” and there’s water in the pan, you may need to install a new pump. Reach us at 816-379-3918 for help.
2. AC Blows Warm Air
If your AC is going but not delivering cold air, its airflow could be obstructed. Or it may not have sufficient refrigerant.
Your unit’s airflow can be reduced by a clogged air filter or filthy condenser.
How to Put in a New Your Air Filter
A dusty filter can create a lot of issues, like:
- Reduced cooling
- Icy refrigerant lines or evaporator coil
- Intermittent cooling
- Increased cooling expenses
- Making your system wear out more quickly
We recommend installing new flat filters once a month, and pleated filters every three months.
If you can’t recall when you last changed yours, shut off your AC totally and take out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It could also be located in an adjoining filter case or wall-mounted return air grille.
Tilt the filter up to your light fixture. If you see a lot of dust, you certainly should replace it.
How to Clean Your Cooling Equipment
Brush, grass and sticks can block your condensing system. This may reduce its airflow, lower its energy efficiency and change your comfort. Here’s how you can get your system running well again.
- Switch off the electrical current fully at the breaker or outside switch.
- Get rid of yard debris around the equipment. Once you’ve gotten rid of bigger clutter within a two-foot range, you can use a paint brush or vacuum to carefully remove dirt from the unit’s fins. Kinked fins can also hurt capability, so you can attempt to correct them with a small knife.
- Lift off the top of your air conditioner and take out any leaves or grass clippings that has accumulated. Then clean the condenser fan with a damp rag.
- Use a hose nozzle to gingerly take off dirt on the fins from inside the system. Be careful to avoid getting water on the fan motor.
- Replace the top and restore the power.
Low Refrigerant Levels
When air conditioning equipment doesn’t have enough refrigerant, they’ll struggle to remove heat and humidity from your rooms.
Here are several indications that your equipment is seeping refrigerant:
- It takes a long time to cool your house and you’re continually lowering the thermostat.
- Cooling coming through the ducts isn’t as chilled as it should be.
- You’re hearing fizzing or gurgling noises when cooling works.
- Your evaporator coil is iced over on account of having difficulty handling warmth.
Worried your unit is losing refrigerant? You need a qualified heating and cooling service specialist to fix the leak and refill the right level of refrigerant in your equipment. Call us at 816-379-3918 for assistance.
3. AC Not Blowing Enough Air
When it seems like you’re not having enough cool air, there’s probably a clog or disconnection somewhere in your air conditioning system.
- The beginning stage is looking at your air filter. Buy a new one if it’s dusty.
- Then check the registers are free around your home.
- If you’re still not experiencing adequate chilled air, you should have your duct system inspected by a specialist like Colvin's Heating and Cooling. Your ductwork might need to be serviced or relinked in tricky locations like your attic, basement or crawl space.
