Rhino One of the worst things that can happen to a household in the hot summer months is for the HVAC system to stop working. If you find yourself in this situation, here are some tips to fix your AC until you can get a certified professional to investigate the problem. Remember, the average lifespan of an AC is about 12 years. If you find you are not feeling comfortable in your house and your AC is failing you, the first thing to check is your drain line. Is water leaking from it? Is it clogged or disconnected? Is your system constantly cycling on and off? If so, it could be a thermostat issue, or the evaporator unit, fan or condenser need to be cleaned. If your AC isn’t getting cool enough, it is recommended you allow better air flow by clearing away plants and debris from the outside unit. Aim for 24 inches of clearance around it and 5 feet on top. Do not underestimate how important airflow is to creating a cool environment. Try to create shade for your outside unit, this can help increase efficiency. Change your air filter (this should be done every 30 to 60 days) and replace worn out insulation on the refrigerant line. If your AC will not switch on, make sure power is reaching the unit. There could be a tripped fused so take a look at the circuit breaker. Make sure the thermostat is set correctly to cool! It seems obvious, but a family member could have changed it without you knowing. If your unit is making some abnormal noises such as a buzzing or rattling noise, it could be as simple as a screw coming loose, or as serious as a bent blade in the fan or a motor issue. Try some tightening of obvious screws and lubricate parts to see if it helps. If it doesn’t, it is time for a professional to take a look! If your unit won’t even kick on, then you may have a burnt out compressor. This can be expensive to fix and you may find it cheaper to buy a new unit.
