When it’s a warm summer day in Saint Louis, nothing could be worse than realizing your air conditioner isn’t working the way it should. The last thing you want to do is call for cooling system service. But your AC is a fairly complex system, so it can be hard to determine what’s causing the problem solo.

That’s why Morgner Inc. Air Conditioning & Heating created this informational guide to help you find out what may be happening with your home comfort system. Below, you’ll see some prevailing reasons your home is feeling a little too warm. And while a couple of these are simple] DIY tasks, you may still need to call in a professional for AC repair.

And if you do, Morgner Inc. Air Conditioning & Heating is prepared to take care of your home. Here are five reasons why your air conditioner may not be cooling your home in Saint Louis.

1. Your Device Settings Could Be Incorrect

Everyone adjusts their thermostat a bit differently to suit their personal requirements. Yet, a number of homeowners make the error of setting their thermostat to “On” as opposed to “Auto.” Because of this setting, the fan in your system will continue to blow even after you’ve attained your preferred temperature.

This can feel like your vents are distributing warmish air, when actually it’s only using the fan on a more regular basis than required. Try switching this setting and find out if things seem better.

2. Your HVAC Needs to Be Cleaned

There are two primary areas to check for dirt or dust buildup when your air conditioner doesn’t feel like it is operating correctly.

Before anything else, examine your AC system’s filter. If you don’t change your filter often enough, buildup can make it hard for air to flow through and cool your space. If your filter is noticeably dirty or dusty, it’s likely time to replace it. (And for best operation, you should change it about once every three months at the very least.)

If your filter appears fine, go to your external unit. Make sure there’s adequate clearing around it and clear away plants or dirt close by. This part of your system lets off the heat from your space. If the coils outside are blocked, you won’t be feeling comfortable in your home.

We advise scheduling professional air conditioner maintenance each year to keep your equipment operating smoothly and to keep your warranty valid.

3. Your Unit is Losing Refrigerant

Refrigerant is the substance that conditions the air in your space. It runs between your indoor and outdoor system pieces to grab and let off heat, to help your home keep cool. If there is a crack along the way, you won’t be feeling cool again until you set professional air conditioning repair.

Signs of a refrigerant leak include a decline in chilled air, higher electric bills, frozen evaporator coils and unusual hissing noises coming from your HVAC.

If you think refrigerant might be leaking, call Morgner Inc. Air Conditioning & Heating for air conditioner repair as soon as possible. Refrigerant can also be hazardous to your family’s health.

4. One or More Parts Need to Be Replaced

Your system is made up of a few essential parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one of these is not working as it should, your home comfort will suffer.

Our Morgner Inc. Air Conditioning & Heating experts are well-trained and knowledged in HVAC. They can help you diagnose and repair any trouble.

5. Your System Has to Be Replaced

If your AC is more than 10 years old, it may be a good time to think about new air conditioner installation. As your system gets up there in years, it sadly won’t function as well as it once did. And it might be making your home too warm.

If your HVAC unit is more current but still isn’t cutting it, it may be the wrong size for your house. Air conditioners are not one-size-fits-all. A cooling system that’s not powerful enough just can’t chill a house the way a properly sized system can.
