Air Conditioner Repair Checklist
1. AC Won’t Turn On
There can be a couple of reasons why your central AC system won’t work: a blown circuit breaker, wrong thermostat settings, a switched off switch or an overflowing condensate drain pan.
Overloaded Circuit Breaker
Your AC won’t run when you have an overloaded breaker.
To check if one has tripped, go to your home’s main electrical panel. You can locate this metallic fixture on the wall in the basement, garage or closet.
- Ensure your hands and feet are free of moisture 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 switch will be in the middle or “off” position.
- Quickly move the lever back to the “on” position. If it instantly trips again, don’t reset it and reach us at 512-937-2001. A breaker that keeps flipping may signal your residence has an electrical issue.
Inaccurate Thermostat Settings
If your thermostat isn’t signaling your system to work, it won’t switch on.
The main part is checking it’s on “cool” and not “heat.” Otherwise your AC may not switch on. Or you might get. heated air coming from vents since the furnace is going instead.
If you’re using a traditional thermostat:
- Replace the batteries if the monitor is blank. If the screen is displaying jumbled characters, buy a new thermostat.
- Check the proper setting is showing. If you can’t alter it, cancel it by dropping 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 lower than the space’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is adjusted correctly, you should receive refreshing air fast.
If you rely on a smart thermostat, like one produced by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for help. If it still won’t work, contact us at 512-937-2001 for assistance.
Turn-Off Switch
Your air conditioner usually has a shut-down device around its outside unit. This switch is generally in a metal box hung on your house. If your unit has recently been repaired, the device may have accidentally been positioned in the “off” position.
Clogged Condensate Drain Pan
Condensate drain pans hold the extra water your AC takes out of the air. This pan is located either beneath or within your furnace or air handler.
When there’s an obstruction or clogged drain, water can become concentrated and prompt a safety feature to stop your unit.
If your pan has a PVC pipe or drain, you can clear the surplus condensation with a special pan-cleaning capsule. You can purchase these capsules at a home improvement or hardware retailer.
If your pan has a pump, locate the float switch. If the mechanism is “up” and there’s water in the pan, you could need to replace the pump. Reach us at 512-937-2001 for support.
2. AC Blows Warm Air
If your AC is running but not delivering cold air, its airflow could be clogged. Or it might not have sufficient refrigerant.
Obstructed Airflow
Your equipment’s airflow can be reduced by a clogged air filter or dirty condenser.
How to Change Your Air Filter
A dusty filter can create countless troubles, such as:
- Lower cooling
- Frosted refrigerant lines or evaporator coil
- Intermittent cooling
- Increased electricity bills
- Making your system break down faster
We suggest replacing flat filters every four weeks, and creased filters every three months.
If you can’t recall when you last changed yours, switch off your unit totally and remove the filter. You can locate the filter in your furnace or air pump’s blower compartment. It might also be situated in an attached filter holder or wall-mounted return air grille.
Angle the filter up to the sunshine. If you see a lot of dust you should replace it.
How to Clean Your Air Conditioning Equipment
Brush, plants and shrubbery can obstruct your condensing system. This could limit its airflow, impact its energy efficiency and change your comfort. Here’s how you can get your equipment working properly again.
- Switch off the electrical current completely at the breaker or outside switch.
- Clear yard rubbish around the equipment. Once you’ve cleared all the debris within a two-foot space, you can use a fine-bristled brush or vacuum to gingerly remove dirt from the equipment’s fins. Crooked fins can also hurt efficiency, so you can attempt to correct them with a small knife.
- Use a hose nozzle to slowly remove gunk off the fins from inside the system. Make sure to avoid getting liquid on the fan motor.
- Put the top back on and turn on the power.
Not Enough Refrigerant
When cooling systems don’t have sufficient refrigerant, they’ll struggle to remove heat and humidity from the air.
Here are a couple of indications that your system is seeping refrigerant:
- It takes too long to lower the temperature in your rooms and you’re constantly decreasing the temperature on the thermostat.
- Air conditioning moving through the ducts isn’t as chilly as it should be.
- You’re hearing fizzing or burbling sounds when the AC is on.
- Your evaporator coil is icy as a result of having an issue absorbing humidity.
Think your unit is seeping refrigerant? You need a authorized heating and cooling service specialist to repair the leak and replenish the proper amount of refrigerant in your system. Get in touch with us at 512-937-2001 for support.
3. AC Not Blowing Enough Air
When it seems like you’re not having adequate amounts of cool air, there’s possibly a blockage or separation somewhere in your air conditioning system.
- The first place is checking your air filter. Replace it if it’s dirty.
- Then check the registers are open across your residence.
- If you’re still not experiencing adequate cold air, you should have your duct system checked by a specialist like Miller Climate Control LLC. Your duct system could need to be fixed or relinked in difficult areas like your attic, basement or crawl space.
