1. AC Won’t Turn On
There can be a few explanations why your air conditioning won’t start: a triggered circuit breaker, inaccurate thermostat settings, a turned off switch or a full condensate drain pan.
Overloaded Circuit Breaker
Your cooling won’t work when you have an overloaded breaker.
To determine if one has gotten overloaded, find your residence’s main electrical panel. You can spot this gray device on the wall in the basement, garage or closet.
- Make sure 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” location. If it’s tripped, the lever will be in the in between or “off” spot.
- Firmly shift the breaker back to the “on” position. If it immediately triggers again, don’t reset it and contact us at 928-244-8840. A fuse that keeps turning off might indicate your home has electrical trouble.
Incorrect Thermostat Settings
If your thermostat isn’t giving a sign to your system to run, it won’t activate.
The first step is ensuring it’s switched to “cool” and not “heat.” Otherwise your air conditioning might not start running. Or you might get hot air moving from vents because the furnace is running instead.
If you’re using a regular thermostat:
- Replace the batteries if the screen is empty. If the screen is presenting garbled numbers, get a new thermostat.
- Make sure the proper option is displaying. If you can’t change it, override it by dropping the temperature and pushing the “hold” button. This will make your AC start if the configuration is not right.
- Attempt to set the thermostat 5 degrees lower than the room’s temperature. Your AC won’t start if the thermostat is identical to the house’s temperature.
Once your thermostat is set accurately, you should begin getting cool air promptly.
If you rely on a smart thermostat, including ones made by Nest, Ecobee, Lux, Honeywell or Bosch, check the manufacturer’s website for help. If you still can’t get it to work, contact us at 928-244-8840 for help.
Your AC typically has a power-cutting lever around its outside unit. This device is typically in a metal box attached to your house. If your unit has recently been repaired, the device may have inadvertently been placed in the “off” location.
Blocked Condensate Drain Pan
Condensate drain pans hold the surplus water your equipment pulls from the air. This pan can be situated either below or in your furnace or air handler.
When there’s an obstruction or backed up drain, water can accumulate and initiate a safety control to stop your equipment.
If your pan includes a PVC pipe or drain, you can get rid of the additional condensation with a special pan-cleaning capsule. You can get these tabs at a home improvement or hardware shop.
If your pan involves a pump, find the float switch. If the switch is “up” and there’s water in the pan, you could need to install a new pump. Contact us at 928-244-8840 for support.
2. AC Blows Warm Air
If your system is running but not cooling, its airflow might be blocked. Or it might not have adequate refrigerant.
Your equipment’s airflow can be restricted by a blocked air filter or filthy condenser.
How to Put in a New Your Air Filter
A dusty filter can cause numerous issues, including:
- Lower cooling
- Icy refrigerant lines or evaporator coil
- Uneven cooling
- Larger cooling expenses
- Leading your system to wear out sooner
We suggest changing flat filters once a month, and pleated filters every three months.
If you can’t recall when you last replaced yours, turn off your unit fully and take out the filter. You can locate the filter in your furnace or air pump’s blower compartment. It might also be located in an adjoining filter holder or wall-mounted return air grille.
Hold the filter up to your light fixture. If you see a lot of dust, you need to get a new one.
5 Tips on Cleaning Your Air Conditioning System
Greenery, plants and sticks can get in the way of your condensing system. This could limit its airflow, lower its energy efficiency and change your comfort. Here’s how you can get your equipment running well again.
- Switch off the electrical current totally at the breaker or external lever.
- Get rid of vegetation rubbish around the equipment. Once you’ve cleared bigger clutter within a two-foot area, you can use a paint brush or vacuum to slowly remove dirt from the equipment’s fins. Bent fins can also impact capability, so you can attempt to reshape them with a small knife.
- Lift off the top of your system and remove any leaves or grass clippings that has accumulated. Then wipe down the condenser fan with a wet scrap cloth.
- Use a hose nozzle to gingerly remove gunk off the fins from inside the unit. Be careful to avoid getting liquid on the fan motor.
- Replace the top and turn on the power.
Not Enough Refrigerant
When cooling systems don’t have enough refrigerant, they’ll struggle to remove heat and humidity from your residence.
Here are several flags that your unit is seeping refrigerant:
- It takes a long time to cool your residence and you’re regularly decreasing the temperature on the thermostat.
- Air conditioning coming through the vents isn’t as chilly as it should be.
- You’re hearing fizzing or gurgling racket when cooling runs.
- Your evaporator coil is frozen because it’s having difficulty absorbing humidity.
Think your system is seeping refrigerant? You need a certified heating and cooling service expert to repair the leak and restore the right measurement of refrigerant in your system. Get in touch with us at 928-244-8840 for assistance.
3. AC Not Blowing Enough Air
When it seems like you’re not getting enough cool air, there’s usually a clog or separation inside your AC unit.
- The first step is examining your air filter. Replace it if it’s filthy.
- Then ensure the vents are free across your rooms.
- If you’re still not experiencing adequate chilled air, you should have your ducts examined by a expert like Connolly Electric & Mechanical. Your ductwork might need to be serviced or hooked up again in difficult areas like your attic, basement or crawl space.
