When it’s a hot summer day in Lincoln, nothing could be worse than recognizing your air conditioner isn’t performing the way it is supposed to. The last thing you want to do is schedule air conditioner service. But your AC is a pretty complex system, so it can be difficult to determine what’s creating the issue without training.

That’s why AW Heating & Air Conditioning wrote this informational guide to help you figure out what might be taking place with your cooling system. From here, you’ll see some typical situtations that explain why your home is feeling too warm. And even though a few of these are simple] DIY projects, you might need to call in a skilled technician for cooling system repair.

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

1. Your System Settings Could Be Off

Every family uses their thermostat a touch differently to suit their individual requirements. Even so, a number of families make the misstep of setting their thermostat to “On” as opposed to “Auto.” With this setting, the fan in your air conditioner will continue to blow even when you’ve attained your preferred temperature.

This can appear like your ducts are distributing warm air, when actually it’s only using the fan more often than necessary. Try switching this setting and find out if things cool off.

2. Your HVAC Needs to Be Cleaned

There are two primary places to investigate for dirt or dust accumulation when your home comfort system doesn’t appear to be performing correctly.

Firstly, examine your system’s filter. If you don’t change your filter routinely, buildup can make it more labor intensive for air to pass through and lower the temperature your house. If your filter is noticeably dirty or dusty, it’s probably time to replace it. (And as a rule, you have to replace it about once every three months at least.)

If your filter appears clean, go to your external unit. Double check there’s adequate space around the unit and clear away plants or litter stuck there. This piece of your AC discharges the heat from within your home. If the coils outside are congested, you won’t be comfortable in your home.

We suggest setting professional air conditioner maintenance each year to keep your equipment running properly and to keep your warranty valid.

3. Your AC is Releasing Refrigerant

Refrigerant is the substance that cools the air in your house. It runs between your indoor and outdoor system pieces to absorb and discharge heat, to help your house keep comfortable. If there is a crack along that path, you won’t be feeling comfortable again until you schedule professional air conditioning repair.

Signs of a refrigerant leak include a drop in conditioned air, higher electric expenses, frozen evaporator coils and strange hissing noises coming from your HVAC.

If you are worried refrigerant might be leaking, call AW Heating & Air Conditioning for air conditioner repair as soon as possible. Refrigerant can also be harmful to your family’s health.

4. One or More Pieces Should Be Replaced

Your AC contains a couple essential parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If any one of these is not working as it should, your home comfort is hurt.

Our AW Heating & Air Conditioning experts are trained and knowledged in HVAC. They can help you find and mend any problem.

5. Your Air Conditioner Has to Be Upgraded

If your AC is over 10 years old, it could likely be a good time to think about new air conditioner installation. As your system gets up there in years, it unfortunately won’t run as well as it once did. And it might be making your space uncomfortable.

If your HVAC unit is more current but still isn’t keeping you cool, it may be the wrong size for your living space. AC units are not all the same size. An AC that’s not powerful enough just can’t cool a house the way an appropriately sized AC can.
