1. AC Won’t Turn On
There can be a couple of causes why your AC unit won’t cool: a triggered circuit breaker, inaccurate thermostat settings, a turned off switch or an overflowing condensate drain pan.
Tripped Circuit Breaker
Your cooling won’t start when you have an overloaded breaker.
To determine if one has tripped, locate your home’s main electrical panel. You can locate this silver device 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.
- Look for the breaker identified “AC” and confirm it’s in the “on” location. If it’s overloaded, the lever will be in the middle of the panel or “off” position.
- Firmly transfer the switch back to the “on” spot. If it instantaneously trips again, leave it alone and get in touch with us at 727-369-6195. A switch that keeps turning off may signal your house has an electrical issue.
Incorrect Thermostat Settings
If your thermostat isn’t telling your system to work, it won’t switch on.
The key part is checking it’s switched to “cool” and not “heat.” Otherwise your air conditioner might not switch on. Or you might get hot air blowing from vents since the heat is on instead.
If you have a regular thermostat:
- Put in new batteries if the monitor is clear. If the monitor is displaying garbled numbers, buy a new thermostat.
- Ensure the right setting is showing. If you can’t update it, cancel it by lowering the temperature and pressing the “hold” button. This will make your AC start if programming is incorrect.
- Attempt to set the thermostat 5 degrees colder than the room’s temperature. Your AC won’t cool if the thermostat matches the room’s temperature.
Once your thermostat is calibrated accurately, you should begin getting cool air promptly.
If you have a smart thermostat, like one produced by Nest, Ecobee, Lux, Honeywell or Bosch, go to the manufacturer’s website for assistance. If you’re still having problems, contact us at 727-369-6195 for support.
Turn-Off Switch
Your system usually has a power-cutting switch around its outdoor unit. This switch is typically in a metal box hung on your house. If your AC has recently been repaired, the device may have accidentally been placed in the “off” position.
Blocked Condensate Drain Pan 
Condensate drain pans catch the extra condensation your system removes from the air. This pan can be found either below or within your furnace or air handler.
When there’s an obstruction or blocked drain, water can become concentrated and prompt a safety control to switch off your unit.
If your pan includes a PVC pipe or drain, you can clear the additional water with a custom pan-cleaning capsule. You can purchase these tabs at a home improvement or hardware retailer.
If your pan involves a pump, look for the float switch. If the lever is “up” and there’s moisture in the pan, you could need to replace the pump. Reach us at 727-369-6195 for support.
2. AC Blows Warm Air
If your AC is going but not cooling, its airflow could be blocked. Or it may not have adequate refrigerant.
Blocked Airflow
Your unit’s airflow can be reduced by a plugged air filter or filthy condenser.
How to Put in a New Your Air Filter
A dirty filter can lead to countless troubles, such as:
- Reduced cooling
- Frosted refrigerant lines or evaporator coil
- Uneven cooling
- Bigger energy expenses
- Making your system stop working more quickly
We recommend changing flat filters once a month, and accordion filters every three months.
If you can’t remember when you last changed yours, shut off your equipment completely and take out the filter. You can find the filter in your furnace or air pump’s blower compartment. It may also be located in a connected filter box or wall-mounted return air grille.
Hold the filter up to the light. If you can’t see through it, you should buy a new filter.
5 Steps to Cleaning Your Air Conditioning Unit
Weeds, plants and bushes can get in the way of your condensing system. This can restrict its airflow, make it less energy efficient and change your comfort. Here’s how you can get your equipment running smoothly again.
- Switch off the electrical current fully at the breaker or outside device.
- Clear plant rubbish around the equipment. Once you’ve removed bigger clutter within a two-foot area, you can use a soft brush or vacuum to gingerly clean the equipment’s fins. Deformed fins can also impact effectiveness, so you can attempt to reshape them with a blunt knife.
- Lift off the top of your AC and pull out any leaves or grass clippings that has built up. Then wipe down the condenser fan with a damp rag.
- Use a hose nozzle to gingerly clean the fins from inside the system. Be careful to avoid getting water on the fan motor.
- Install the top again and restore the power.
Insufficient Refrigerant
When AC systems don’t have adequate refrigerant, they’ll have difficulty removing heat and humidity from the air.
Here are several indications that your equipment is leaking refrigerant:
- It takes a long time to lower the temperature in your space and you’re constantly lowering the thermostat.
- Air conditioning moving through the vents isn’t as chilly as it should be.
- You’re noticing whistling or bubbling noises when cooling runs.
- Your evaporator coil is frosted due to having difficulty absorbing humidity.
Worried your unit is losing refrigerant? You need a qualified heating and cooling service professional to fix the leak and replenish the proper level of refrigerant in your unit. Contact us at 727-369-6195 for assistance.
3. AC Not Blowing Enough Air
When it appears like you’re not getting enough cold air, there’s probably a blockage or detachment somewhere in your cooling system.
- The initial step is checking your air filter. Get a new one if it’s dirty.
- Then check the vents are open around your residence.
- If you’re still not getting ample cold air, you should have your duct system inspected by a specialist like Hale's Air Conditioning Services Inc. Your ductwork might need to be fixed or hooked up again in limited space spots like your attic, basement or crawl space.
