    1. Check Your Circuit Breaker

    Ever wondered how you can use so many appliances at once without your house burning down? Well, it’s not down to magic or luck; it’s because of your circuit breaker.

    Your circuit breaker keeps you safe in case your appliances start to malfunction. If there is a sudden power surge, it will cut off all the electricity. This is to prevent anything from sparking or catching fire.

    Your HVAC system will have its own switch on the circuit breaker. If the breaker has tripped, then the power would have been cut off.

    So, to get your HVAC system back up and running, simply hit the reset button or switch on the circuit breaker. It should turn back on immediately without any issues.

    But, if your circuit breaker keeps tripping, then there could be a problem with it or your HVAC system. At this point, you should call in an expert to fix it, so view here for more information.

    2. Check the Air Filter

    This is, in fact, a handy air conditioner maintenance tip.

    Your HVAC system air filter is working around the clock and does an essential job. Before hot/cool air starts circulating around your home, the air filter has already removed things like:

    • Dust
    • Mold
    • Debris

    This ensures that the air you and your family are breathing is as clean as possible. As a result, it should reduce allergy and respiratory symptoms.

    But, because your air filter is constantly working hard, it’s prone to problems. It’s easy for it to become dirty, blocked, and even damaged because of this you will want to make sure your 20x25x1 furnace filter is checked and changed regularly. If your HVAC system isn’t running at optimal performance, you may need to hire a professional to come out and do an annual maintenance check to see if, or how badly your system is damaged.

    When this happens, the air quality reduces and, the air conditioning system may malfunction.

    You should check your air filter at least once a month to ensure it’s working properly. To do this, just shine a bright light through it. If you can see the light through the opposite side, then it’s ok.

    But if not, it’s time to replace it.

    3. Check Your Thermostat

    Everyone will have a thermostat to control the temperature of the air coming into the house. Unfortunately, sometimes these can malfunction too.

    Go to your thermostat and check it’s on the right setting. Ensure that it’s set to the temperature you want and not programmed too high or low.

    Sometimes this can happen, and all you need to do is adjust it. You’ll then have cool/warm air flowing through again in no time.

    But, if it doesn’t seem to be working, then check the batteries. These can occasionally need replacing, making it a quick fix.

    Finally, if none of these methods work, then it’s at this point you should call the experts for help.

    4. Check the Outdoor Air Conditioning Unit

    The outdoor unit can often cause AC problems.

    Due to being located where it is, it is prone to damage, especially from severe weather. It can even start sinking, which throws the system off balance.

    When this happens, it will stop operating correctly.

    So, you should check the outdoor unit as often as you can to ensure it’s still level and there is no sign of damage. If it has started to sink, then try to level it asap.

    5. Ensure the Registers Are Open

    This is one of the simplest solutions to fix a broken AC system.

    If your thermostat is working correctly and you cannot detect any damage within the system, then check the registers. These are grate-like metal plates that are located at vent openings.

    They’re designed to simply control the airflow into your property. So, if they’re closed, no air can pass through.

    In this case, all you have to do is open them back up. And just like that, you’ll have cool/hot air flowing through again.

    6. Clean the Condenser Coils

    Condenser coils are located in your outdoor unit. Due to where they are, it’s common for them to build up with dust and dirt.

    When this happens, they stop working efficiently.

    So, every couple of months, go outside and give the coils a wipe down. Even the smallest amount of dirt can make a difference to the temperature of the air passing through.
