Signs Your System May Not Be Operating Efficiently

You may wonder how to tell when efficiency has dropped. Some signs your system is experiencing this problem include:

Increased Costs

One of the most obvious signs of AC inefficiencies is if your utility costs are going up. When an AC isn’t operating efficiently, it requires more energy.

If you notice a significant jump in your usage and costs, then it’s a good idea to have the system inspected and cleaned. The professional will be able to determine the underlying cause of the increased costs.

Frequent Cycling

Your thermostat is the “brain” behind your AC system. If you notice it starting to cycle on and off too often, it may be an indication the thermostat needs to be replaced. Everyday use and dust can wear on the internal mechanism of the thermostat.

Another reason your system may be cycling frequently is the compressor. It’s best to have a professional determine the precise issue.

Ice on the Compressor

If ice starts to build on your AC unit, it’s a definite sign that you need professional repairs. Ice can begin to build-up due to a leak in the coolant line.

Another cause of this problem is if damage to your coils has occurred. A dirty filter may also cause this problem. If there is ice, you can feel confident that your unit isn’t operating as efficiently as it should.

Unusual Sounds

Each appliance in your home is going to have its own set of unique sounds. Chances are you have gotten used to some of the sounds that occur due to the regular operation of your unit.

If you notice something unusual, then it’s a good idea to shut everything down, to prevent the issue from getting worse and book a service call.

Now that you know the signs of inefficiency, it’s time to get into what you can do about it. Just Call AC Heating In San Mateo.
