Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be several explanations why your air conditioning won’t run: a blown circuit breaker, wrong thermostat settings, a turned off switch or an overfull condensate drain pan.
Tripped Circuit Breaker
Your air conditioner won’t turn on when you have an overloaded breaker.
To find out if one has blown, find your home’s main electrical panel. You can locate this gray box on the wall in the basement, garage or closet.
- Ensure your hands and feet are free of moisture before you touch the panel or breakers.
- Find the breaker labeled “AC” and ensure it’s in the “on” position. If it’s triggered, the switch will be in the middle or “off” position.
- Quickly shift the lever back to the “on” position. If it immediately triggers again, don’t reset it and get in touch with us at 276-302-0076. A switch that keeps flipping may indicate your home has an electrical issue.
Inaccurate Thermostat Settings
If your thermostat isn’t signaling your equipment to start, it won’t switch on.
The main step is checking it’s switched to “cool” and not “heat.” Otherwise your air conditioner will probably not start running. Or you could have heated air coming from vents because the heater is running instead.
If you rely on a traditional thermostat:
- Replace the batteries if the monitor is empty. If the screen is displaying garbled numbers, get a new thermostat.
- Make sure the right program is showing. If you can’t alter it, override it by dropping the temperature and pushing the “hold” button. This will force your AC to work if programming is incorrect.
- Try setting the thermostat 5 degrees cooler than the room’s temperature. Your AC won’t start if the thermostat is identical to the room’s temperature.
Once your thermostat is set properly, you should begin getting cold air quickly.
If you have a smart thermostat, like one produced by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for assistance. If you’re still having problems, contact us at 276-302-0076 for support.
Your system typically has a power-cutting lever near its outdoor unit. This lever is generally in a metal box mounted on your home. If your AC has recently been serviced, the switch may have unintentionally been positioned in the “off” position.
Clogged Condensate Drain Pan
Condensate drain pans catch the surplus liquid your AC takes out of the air. This pan can be found either below or in your furnace or air handler.
When there’s an obstruction or backed up drain, water can build up and prompt a safety setting to turn off your air conditioner.
If your pan involves a PVC pipe or drain, you can get rid of the surplus liquid with a special pan-cleaning capsule. You can purchase these tabs at a home improvement or hardware retailer.
If your pan includes a pump, look for the float switch. If the lever is “up” and there’s liquid in the pan, you could need to install a new pump. Contact us at 276-302-0076 for support.
2. AC Blows Warm Air
If your AC is on but not providing cold air, its airflow may be congested. Or it could not have sufficient refrigerant.
Your unit’s airflow can be restricted by a clogged air filter or dirty condenser.
How to Put in a New Your Air Filter
A filthy filter can cause countless problems, such as:
- Reduced airflow
- Icy refrigerant lines or evaporator coil
- Uneven cooling
- Bigger electricity costs
- Leading your system to break down more quickly
We recommend replacing flat filters monthly, and pleated filters every three months.
If you can’t remember when you last replaced yours, switch off your AC totally and pull out the filter. You can find the filter in your furnace or air pump’s blower compartment. It could also be found in a connected filter box or wall-mounted return air grille.
Tilt the filter up to your light fixture. If you see a lot of dust, you should buy a new filter.
5 Steps to Cleaning Your Air Conditioning Unit
Weeds, grass and bushes can obstruct your condensing equipment. This could limit its airflow, impact its energy efficiency and affect your comfort. Here’s a method you can follow to get your equipment working smoothly again.
- Shut off electricity fully at the breaker or external device.
- Remove vegetation rubbish around the unit. Once you’ve cleared all the debris within a two-foot radius, you can use a fine-bristled brush or vacuum to carefully remove dirt from the condenser fins. Kinked fins can also impact effectiveness, so you can attempt to correct them with a small knife.
- Lift off the upper part of your air conditioner and remove any leaves or yard waste that has built up. Then wipe off the condenser fan with a moist cloth.
- Use a hose nozzle to gingerly clean the fins from inside the system. Don’t get moisture on the fan motor.
- Replace the top and restore the power.
Low Refrigerant Levels
When AC units don’t have enough refrigerant, they’ll have to work much harder to remove heat and humidity from your residence.
Here are several indications that your unit is seeping refrigerant:
- It takes too long to lower the temperature in your space and you’re constantly turning down the thermostat.
- Air moving through the ducts isn’t as chilled as it should be.
- You’re experiencing hissing or gurgling sounds when cooling works.
- Your evaporator coil is iced over as a result of having an issue handling warmth.
Think your system is seeping refrigerant? You need a licensed heating and cooling service specialist to repair the leak and restore the proper level of refrigerant in your system. Call us at 276-302-0076 for support.
3. AC Not Blowing Enough Air
When it feels like you’re not having enough cold air, there’s probably a blockage or separation somewhere in your air conditioning system.
- The first place is looking at your air filter. Replace it if it’s filthy.
- Then check the vents are open throughout your residence.
- If you’re still not experiencing sufficient cold air, you should have your ductwork examined by a specialist like HCE Systems Inc. Your ducts may need to be fixed or hooked up again in limited space areas like your attic, basement or crawl space.
