Tips to expand the warranty of your Air-conditioner

You've purchased air conditioners and everything is working as it should. There's a Warranty on these units, so it should last quite a few years, right? Yes and No. Warranties are only valid if you service your units on a regular basis. If you fail to do so, the Manufacturer could refuse to fix any fault that may have arisen due to the absence of a full service report.

Here are a couple of FAQ that could give you a better idea of how to look after your Air Conditioner Units.

How often should I have my air conditioner serviced?

Depending on your system, it should be serviced a minimum of once a year, with periodic inspections up to 4 times a year. We suggest scheduling a consultation with Aircon Firm that has respected industry certifications. Based on the age, size and usage of your system, we can tailor a service plan to meet your budget requirements and keep your system running reliably.

Why does my system seem to need more gas (refrigerant) each year?

An air conditioning system that needs recharging of gas (refrigerant) on a regular basis is leaking and needs repair. Leaking gas not only causes your unit to lose cooling capacity and use more energy, it’s also very bad for the environment.

Aircon Firm uses the latest, Eco-friendly gas - R410A to refill air conditioners. Very old air conditioners use the old gas and should your unit not be able to use the new R410A gas, you may have to look at purchasing a new system.

How can I ensure that my air conditioning unit lasts as long as possible?

The best thing you can do to prolong the life of your system is to have it regularly serviced by a professional. In addition, here are a few tips for easy things you can do to avoid costly air conditioning repair:

  • Keep leaves and debris from collecting around your outdoor air conditioning unit. This simple action prevents dirt from clogging up your system, and keeps airflow paths clear.

  • When arranging furniture layouts and carpeting installations, make sure air grills and ductwork are not blocked.

  • Use blinds and shades on east and north facing windows to keep out heat in the summer.

  • Set a timer to reduce air conditioning usage when it’s not needed.

What do the air conditioner ratings mean?

If you’re considering installing a new air conditioning unit, you’ve probably run across many rating acronyms on the sales literature. If it’s all greek to you, here’s a quick explanation of the various ratings:

  • BTU (British Thermal Unit) The size, or cooling capacity, of an air conditioner is indicated by its BTU, or British Thermal Unit. This is a measurement of how much heat the unit can add or remove from the air per hour. The most energy-efficient air conditioner for your needs will have a BTU suited to the size of the space you want to cool.

 

Other factors also have some effect. For instance, the best BTU for your space depends on climatic conditions. It’s also affected by the positioning of the building, the type and quality of the insulation, the type and size of your windows and the height of your ceilings. In general, the recommendation for air conditioners in South Africa is 500 BTU per square meter. For example, a 20 m² room would require an air conditioner with 10 000 BTU.

  • EER (Energy Efficiency Ratio) is the cooling capacity of a unit – its BTU – divided by the kilowatts per hour (kWh) it uses at full power. Say a 10 000 BTU air conditioner were to use 1 200 kWh. It’s EER can be calculated as 10 000 / 1 200, which equals 8.3.

What is the difference between Inverter and Non-Inverter Systems?

Two main kinds of air conditioners are inverter and non-inverter systems. The motor in an inverter air conditioner is self-regulating. This means the motor speed varies continually to maintain an even room temperature. In contrast, non-inverter air conditioners have a single-speed motor that frequently turns off and then on again. Inverter air conditioners are more expensive, but save on energy costs over time.
