6 Signs you may Need a Maintenance Check-up

Warmer Weather

As the weather gets warmer, your air conditioning system will be working harder to keep your home or office cool and comfortable. It’s important to ensure that your AC unit is working efficiently and effectively, to avoid potential breakdowns and costly repairs. Here are six signs that you may need a maintenance check-up on your air conditioning system.

Reduced airflow

If you notice that your Air Conditioning unit is not blowing as much air as it used to, it may be a sign that your air filters are clogged, or your system needs a tune-up. Reduced airflow can also be caused by a damaged blower motor or a blocked duct. Low refrigerant levels, or malfunctioning evaporator fans. If this is the case, contact Air Improve today. We can do an annual check-up to ensure your company or personal unit is complying with legislation.

Unusual noises

If you hear unusual noises such as rattling, grinding, or squeaking coming from your AC unit, it’s a sign that something is not working as it should. Identifying the type of noise it’s making can help an engineer to assess the problem over the phone & will in turn make the system easier to fix. Unusual noises can be caused by loose parts, damaged belts, or a malfunctioning compressor.

Bad Smells

If your AC unit is emitting foul odours, it’s a sign that there may be mould or mildew growing inside the system. This can be caused by clogged air filters, condensation build-up, or a dirty evaporator coil. A bad smell in your air conditioning unit will deter you from using the system. Wall-mounted split air conditioners have easily accessible filters that require regular cleaning to keep them functioning optimally. To do this, simply remove the front panel and pull out the filter – no detergents necessary! Simply give it a good wash with some warm water.

High humidity levels

If your home or office feels excessively humid, it may be a sign that your AC system is not functioning properly. High humidity levels can be caused by an oversized AC unit, a malfunctioning compressor, or a clogged air filter.

Increased energy bills

If you notice a sudden increase in your energy bills, it may be a sign that your AC unit is not running as efficiently as it should. Increased energy bills may mean you’re less likely to use the air conditioning unit & therefore, not experience the benefits. Having an engineer inspect this as soon as possible will mean you can resume using the system at an energy-efficient level. This can be caused by a dirty air filter, low refrigerant levels, or a damaged compressor.

Uneven cooling

If your AC unit is not cooling your home or office evenly, it may be a sign that there is a problem with the ductwork or that the system is not properly sized for the space. This can lead to increased energy bills and decreased comfort.


Regular maintenance checks on your air conditioning system can help to ensure that it is working efficiently and effectively. If you notice any of these signs, it’s important to schedule a maintenance check-up with air improve, to address any potential issues before they become more serious. By taking proactive steps to maintain your AC unit, you can help to extend its lifespan and avoid costly repairs in the future.
