Our Air Conditioning Repair in Irving, TX is 100% Guaranteed*

Everyone knows how Summer heat can be hard on their AC unit. Even a new HVAC system needs attention prior to entering the “primetime” cooling season. Ignoring even minor maintenance items can lead to an air conditioner repair in Irving at the worst possible time.

This is why it’s important to be proactive about your AC system. Some air conditioning repair services can be avoided by regularly maintaining your AC unit. For example, a clean condenser coil and a functioning leak detector will optimize the performance of your air conditioner, saving you money in energy costs all year round!

A well-functioning air conditioning unit is integral to the lives of those living in Irving. A cool home serves as a refuge from summer’s brutal heat. If your air conditioning system is not running properly it can be nothing short of miserable during what should otherwise be an enjoyable season.

There is no need for you or your family members (especially those with respiratory conditions) to suffer through uncomfortable temperatures or poor indoor air quality if your AC unit is not cooling as it should. We realize that if you’re reading this, air conditioning maintenance isn’t your focus at the moment.

Instead, let’s discuss what might be causing your cooling system to underperform.

Common Problems Requiring Irving Air Conditioning Service

Here are some common issues that often lead to AC repair service calls in Irving. These include dirty evaporator coils on the outside unit, refrigerant lines that leak, compressor burnout due to low oil, and lack of coolant resulting in insufficient condensation inside the evaporator coil tubes located outdoors. These are common to every HVAC technician, but not every homeowner has the experience to quickly identify the problem.

If you need Irving AC repair service immediately, please give us a call. We’re a family-owned HVAC company, and treat our customers like family as well. Our repair visits are backed by a 100% guarantee*.

Ready for the troubleshooting list? Follow this simple guide below as many of these air conditioning repair steps don’t require mechanical expertise.

1. Air Conditioner Won’t Turn On

There are a few common reasons why your central air conditioning system isn’t running. These reasons might be a switch turned to the wrong setting, a blown circuit, an incorrect thermostat setting, a bad compressor, or a condensate pan that simply needs to be drained. Let’s get into these.

Blown Circuit Breaker

The AC unit won’t come on if you have a tripped breaker. You don’t want to call an HVAC contractor out just to flip this back for you.

Head to the house’s main electrical panel to see if it’s tripped. Most are familiar with this, but if not, it’s a metal box mounted to the wall. It’s often in the garage or a closet since most Irving homes do not have basements.

Don’t forget to make sure your hands and feet are dry before touching the panel or breakers.

Find the one labeled “AC” and double-check that it’s in the “on” position. If not, the breaker will be in the middle or “off” position.

To fix this, just shift the breaker back to the “on” position.

If it trips again, leave it alone and give us a call at 469-200-3100. A breaker that is repeatedly tripping could mean there is a larger electrical problem related to the HVAC system.

Incorrect Thermostat Settings

If the thermostat isn’t signaling your AC to run it won’t be able to turn on. The most important step is to ensure it’s not set to “heat” during the Summer season.

If you’re using a digital programmable thermostat:

Install new batteries if the screen is dark. If the symbols are incorrect or scrambled, the thermostat will need to be replaced.

Make sure it’s set to the correct program. Override it by lowering the temperature and pressing “hold” if you can’t change the program. This will force the AC to start even if the programming is incorrect.

Set the thermostat to a temperature cooler than the current temperature reading. If it’s the same temperature, the AC won’t start.

Once the thermostat is using the correct settings, the cool air should start flowing very quickly if this is the problem.

If you’re using a smart thermostat like Nest, Ecobee, Lux, Honeywell or Bosch, take a look at the manufacturer’s website. If you’re still having trouble, give us a call at 469-200-3100 for help.

Turned Off Switch

The AC most likely has a shutoff switch near the outside unit. This switch is usually inside a metal box mounted to the outside of your home. If the unit has been recently serviced, the switch may still be set to the “off” position and will need to be switched back.

Clogged Condensate Drain Pan

The drain pans collect the excess moisture your system removes from the air. It’s located either under or inside your furnace or air handler.

If there’s a blockage or clog, water can build pressure and trigger a safety feature. This will turn off the system.

If the pan has a PVC pipe or drain, clear the excess water with a special cleaning tablet. You can find these tablets at home improvement or hardware stores. You can also soak it up with an old towel.

If the pan has a pump, you’ll need to locate the float switch. If the switch is set to “up” and liquid has collected in the pan, the pump might need to be replaced.

2. Air Conditioner Blows Warm Air

If you’re getting warm air in the Summer, the airflow could be blocked or you may lack refrigerant to properly cool the air.

Blocked Airflow

Your AC system’s airflow could be affected by a dirty condenser, or more commonly, a clogged filter.

How to Change Your Air Filter

A bad filter can cause lots of problems:

  • Reduced airflow
  • Frozen refrigerant lines or evaporator coil
  • Uneven cooling
  • Increased energy bills
  • Premature system failure

We recommend checking flat filters once a month, and pleated filters every three months. If they are dirty, change them promptly or re-check the following month.

If you can’t remember the last time you changed the filter, turn the system off completely and remove the filter. You can find it in your furnace or air handler’s blower compartment, in an attached filter case, or inside wall-mounted return air grills.

Once you remove it, hold the filter up to the light. If you can’t see through it, it’s time to replace the filter.

How to Clean Your Air Conditioning System

Lots of small debris could block your condensing unit, which limits its airflow and energy efficiency. To get it running smoothly again:

  1. Turn the breaker or outdoor switch off.
  2. Remove all yard waste that has accumulated around the AC in a two-foot radius.
  3. You can then use a brush or vacuum to clean off the condenser fins. Energy efficiency can be affected by bent fins, so carefully try to reshape them.
  4. Remove the top of the AC and any yard waste that has collected inside. Then wipe down the condenser fan with a damp (not wet) cloth.
  5. Use your hose to clean the fins from inside the unit. Be careful not to get water on the fan motor.
  6. After you replace the top, restore the power.

Low Refrigerant in Air Conditioning Unit

It’s much harder to remove heat and humidity from a room when your AC unit doesn’t have enough refrigerant.

Signs your system is leaking:

  • It takes too long to cool your home, and you’re constantly turning down the thermostat.
  • The air that’s blowing does not feel cool.
  • There are hissing or gurgling sounds coming from the AC unit while running.
  • The evaporator coil has frozen since it can’t absorb heat.

If you think your AC is leaking refrigerant, you’ll need a licensed professional to find the leak and add the correct amount of refrigerant to your pressurized system.

3. AC Not Blowing Enough Air

Sometimes your AC runs fine but won’t blow enough air. This could mean there’s a blockage or disconnection hiding somewhere in your system or air duct. Some tips to find this problem are:

  • Start with the air filter. Replace it if it’s dirty.
  • Make sure all registers are open throughout the house.
  • If there’s still not enough air coming through, an air duct may need servicing.

This can be difficult to locate and fix on your own. Let the HVAC professionals at Diamond Blue Air help.
