Addressing Five Common Issues With Air Conditioning Units

By virtue of being climate control experts, we inevitably possess a horde of valuable advice to share regarding air conditioning systems and, in particular, the common issues faced by owners of air conditioning units. Whilst the Unico Range essentially negates the majority of these concerns, we’ve decided to help you identify the common issues you might be facing with your current solution.

Refrigerant Leaks

When an air conditioner is low on refrigerant, this is usually borne of undercharging during installation or leaks. In the case of the latter, simply adding refrigerant will not suffice as a solution - you’ll need trained technician to fix any leak, test the repair and then charge the system with the correct amount of refrigerant.

As a general rule of thumb, the refrigerant charge should exactly match the manufacturer's specification - this will offer you the optimum air conditioning performance and efficiency. Given refrigerant leaks have significant environmental impacts, ensure your refrigerant is neither undercharged nor overcharged.

Sensor Problems

Located behind their control panels, room air conditioners generally have a thermostat sensor, responsible for measuring the temperature of the air entering the evaporative coil. Should this sensor be knocked out of position, for instance, your air conditioner is liable to cycle constantly or perform erratically. To prevent this, we suggest the sensor be located be near the coil, not touching it. To adjust its position, carefully bend the wire that holds it in place or, better still, avoid self-service altogether and call an expert.

Inadequate Maintenance

This is largely common sense, but neglect happens regardless. If you get to the stage where you allow filters and air conditioning coils to become dirty or otherwise neglected, the compressor or fans are likely to fail prematurely - not exactly conducive to an adequately operational air conditioner.

Non-Functional Outdoor Units

If your air conditioner’s outdoor unit is not functional, this is usually indicative of a lack of power, problems with the contactor or even something as fundamental as a faulty thermostat. Due to the absence of outdoor units, this is a concern that is completely negated by the whole Unico Range, particularly the Unico Air.

Frozen Coils

Typically, a frozen coil is indicative of airflow problems; for instance, restrictions caused by obstructed return air ductwork or poorly maintained air filters. Also, consider that frozen indoor coils can also be caused by low refrigerant so, as mentioned above, be vigilant against leaks.

Whilst these problems could be faced by anyone, the financial implications are always more pronounced in a commercial context. For instance, within the hotel and hospitality industry, air-conditioning issues lead to extended room down-time, directly affecting revenue. To help those within this industry specifically, we have  designed handy infographic explaining the features the Unico units offer and how these can also benefit your business and, in particular, hotels.
