Air Conditioner Repair Checklist

1. AC Won’t Turn On

There can be a couple of causes why your AC unit won’t cool: a tripped circuit breaker, wrong thermostat settings, a switched off switch or a full condensate drain pan.

Overloaded Circuit Breaker

Your air conditioning won’t run when you have an overloaded breaker.

To see if one has tripped, find your residence’s main electrical panel. You can spot this metallic box on the wall in the basement, garage or closet.

  • Make sure your hands and feet are dry before you work on the panel or breakers.
  • Look for the breaker marked “AC” and ensure it’s in the “on” position. If it’s triggered, the switch will be in the "off" position.
  • Quickly transfer the breaker back to the “on” spot. If it instantly trips again, don’t reset it and call us at 1-866-781-0111. A fuse that keeps flipping may mean your residence has an electrical issue.

If your thermostat isn’t giving a sign to your air conditioner to work, it won’t turn on.

The first point is making sure it’s switched to “cool” and not “heat.” Otherwise your AC might not turn on. You could also have hot air coming from vents being the heat is going instead.

If you’re using a traditional thermostat:

  • Swap out the batteries if the monitor is blank. If the screen is presenting jumbled characters, replace the thermostat.
  • Ensure the right setting is on the display. If you can’t alter it, override it by dropping the temperature and pressing the “hold” button. This will force your AC to work if the configuration is incorrect.
  • Attempt to set the thermostat 5 degrees colder than the house’s temperature. Your AC won’t work if the thermostat matches the house’s temperature.

Once your thermostat is set correctly, you should begin getting refreshing air fast.

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’re still having problems, call us at 1-866-781-0111 for support.

switch icon Shut-Down Switch

Your AC usually has a shut-down device around its outdoor unit. This device is commonly in a metal box hung on your home. If your unit has recently been repaired, the lever may have accidentally been turned off.

Overflowing Condensate Drain Pan drain pan icon

Condensate drain pans hold the surplus liquid your system takes out of the air. This pan can be situated either under or in your furnace or air handler.

When there’s an obstruction or backed up 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 drain the additional condensation with a formulated pan-cleaning tablet. You can buy these tablets at a home improvement or hardware store.

If your pan includes a pump, locate the float switch. If the lever is “up” and there’s moisture in the pan, you might have to install a new pump. Call us at 1-866-781-0111 for help.

2. AC Blows Warm Air

If your air conditioner is working but not cooling, its airflow may be obstructed. Or it might not have enough refrigerant.

Blocked Airflow

Your system’s airflow can be reduced by a blocked air filter or dirty condenser.

How to Put in a New Your Air Filter

A dusty filter can lead to numerous problems, such as:

  • Limited airflow
  • Frozen refrigerant lines or evaporator coil
  • Inconsistent cooling
  • Increased electricity bills
  • Leading your system to break down faster

We propose installing new flat filters every four weeks, and pleated filters every three months.

If you can’t remember when you last replaced your filter, shut off your unit totally and pull out the filter. You can spot the filter in your furnace or air pump’s blower compartment. It may also be situated in an attached filter holder or wall-mounted return air grille.

Tilt the filter up to the sunshine. If you can’t see any light, you should get a new one.

4 Tips on Cleaning Your AC Equipment

Weeds, grass and shrubbery can obstruct your condensing equipment. This can reduce its airflow, impact its energy efficiency and affect your comfort. Here’s a method you can follow to get your equipment running smoothly again.

  1. Shut off the electrical current completely at the breaker or outside switch.
  2. Get rid of plant rubbish around the equipment. Once you’ve removed all the 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 hurt performance.
  3. Use a hose nozzle to gingerly remove gunk off the fins from inside the equipment. Don’t get water on the fan motor.
  4. Restore the power.

Insufficient Refrigerant

When air conditioning equipment doesn’t have enough refrigerant, they’ll have difficulty removing heat and humidity from your rooms.

Here are several signs that your unit is leaking refrigerant:

  1. It takes an extended amount of time to cool your house and you’re constantly lowering the thermostat.
  2. Cooling blowing through the ducts isn’t as cold as it should be.
  3. You’re noticing hissing or bubbling sounds when the air conditioning is on.
  4. Your evaporator coil is icy on account of having trouble taking on warmth.

Think your unit is losing refrigerant? You need a certified heating and cooling service specialist to take care of the leak and refill the correct amount of refrigerant in your system. Call us at 1-866-781-0111 for help.

3. AC Not Blowing Enough Air

When it seems like you’re not receiving enough chilled air, there’s likely a blockage or separation within your cooling unit.

  • The initial step is checking your air filter. Get a new one if it’s filthy.
  • Make sure the ductwork is open across your house.
  • If you’re still not receiving enough chilled air, you should have your ducts inspected by a professional like McFadden Heating & Cooling. Your duct system may need to be serviced or relinked in limited space spots like your attic, basement or crawl space.
