When it’s a warm summer morning in Omaha, nothing could be worse than registering your home comfort system isn’t performing the way it is supposed to. The last thing you want to do is call for air conditioner service. But your AC is a pretty complicated system, so it can be difficult to determine what’s triggering the issue on your own.

That’s why Interstate Heating & Air Conditioning wrote this guide to help you figure out what could be taking place with your AC. Here, you’ll see a few prevailing reasons your space is feeling too warm. And though a couple of these are straightforward] DIY tasks, you might have to bring in a professional for HVAC repair.

And if you do, Interstate Heating & Air Conditioning is ready to assist. Here are five reasons why your air conditioner may not be cooling your house in Omaha.

1. Your Device Settings Could Be Wrong

Everyone sets their thermostat a bit differently to suit their personal preferences. Even so, a number of homeowners make the error of setting their device to “On” instead of “Auto.” Under this setting, the fan in your AC will continue to push out air even after you’ve attained your set temperature.

This can appear like your AC is pushing out warm air, when really it’s only using the fan more frequently than required. Change this setting and see if things change.

2. Your System Needs a Good Cleaning

There are two main areas to check for dirt or dust accrual when your AC doesn’t feel like it is performing well.

Firstly, examine your HVAC filter. If you don’t change your filter routinely, built-up dust can make it more difficult for air to pass through and lower the temperature your space. If your filter is obviously dirty or dusty, it’s definitely time for a change. (And in general, you have to switch it about once every three months at a minimum.)

If your filter appears fine, head to your external unit. Make sure there’s a reasonable amount of room around your air conditioner and clear away plants or litter close by. This piece of your AC releases the heat from within your space. If the coils outside are blocked, you won’t be feeling cool inside.

We advise setting professional air conditioner maintenance yearly to keep your unit working like it should and to keep your warranty valid.

3. Your System is Losing Refrigerant

Refrigerant is the chemical that chills the air in your house. It runs between your inside and outdoor units to absorb and let off heat, to help your space stay the right temperature. If there is a leak along the way, you won’t be comfortable again until you book professional air conditioning repair.

Signals of a refrigerant leak include a lack of conditioned air, more expensive electric charges, frozen evaporator coils and strange hissing noises originating from your AC.

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

4. One or More Pieces Need to Be Replaced

Your system includes a couple crucial parts. These include the blower, evaporator coils, compressor, fan, condenser coils and expansion valve. If one part is not working as it should, your home comfort suffers.

Our Interstate Heating & Air Conditioning experts are trained and skilled in all areas of HVAC. They can help you diagnose and mend any problem.

5. Your AC Needs to Be Replaced

If your system is older than 10 years old, it is probably about time to look into 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 may be making your home too warm.

If your system is newer but still isn’t properly cooling your home, it may be too small for your house. AC units are not all the same size. A cooling system that’s not powerful enough simply can’t chill a place the way a properly sized AC can.
