Air Conditioning Maintenance

What Climate Maintenance

What Climate never underestimate the importance of a regularly maintained system. It runs efficiently keeping costs down, and without doubt, leads to a longer life span subsequently protecting your valuable investment.

Maintenance is essential for air conditioning units not only to uphold warranties but also for breakdown prevention and avoiding costly repairs. An air conditioner's filters, coils, and fins require regular maintenance for the unit to function efficiently and effectively throughout its lifespan.

Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases. 

Importance of Air Conditioning Filters

One of the most important routine maintenance tasks for the efficiency of your air conditioning unit is to clean or replace its filters. Blocked, dirty filters have a huge impact on restricting normal airflow and restrict the system's efficiency greatly.

With normal airflow obstructed, the air that can no longer travel through the filter will gather directly into the evaporator coil and impair the coil's ability to absorb heat. 

Replacement of Air Conditioning Filters

Replacing a clogged filter with a clean one will certainly lower your air conditioner's energy consumption. Some types of filters can be used more than once, others must be replaced. They are available in different varieties and efficiencies. 

Replacement or cleaning of an air conditioning system's filter can sometimes be needed every two or three months during the summer season. Filters may need more frequent attention if the air conditioning is in constant use and is subjected to dusty conditions.

Evaporator and Condensing Coils

The air conditioning unit's indoor evaporator and external condenser coil collect dirt over months and years of usage. A clean/new filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and covers the coil, reducing its ability to absorb heat. Avoiding this problem is achievable by checking your evaporator coil annually and cleaning it as necessary.

Outdoor condenser coils can also become dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins.

You should actively try to reduce dirt and debris near the condenser unit from things like falling leaves and general rubbish build up. Cleaning the area around the coil, removing any debris, weeds, and foliage back a suitable distance to allow for adequate airflow around the condenser.

Care of Aluminium Coil Fins

The aluminum fins on the condenser and evaporator coils are easily damaged and can restrict airflow through the coil. Care must be taken to ensure these stay in optimal condition and free from damage.

What Climate can offer a range of protective cages for the external units should security or vandalism be an issue.

Drainage for Condensate

Having clean unrestricted drainage is another important factor in the regular upkeep of an air conditioning unit and something that is always checked on regular maintenance. Pumps that remove condensate are tested, and gravity-fed drains routinely for blockages. Clogged drains can lead to a unit overspilling and the resulting excess moisture can stain walls or flooring.

What Climate recommends a six-monthly maintenance schedule. We also offer multiple unit discounts or a bespoke package to suit your needs, which can ensure your air conditioners are always performing at the highest possible level.

Our trained engineers will undertake a full health check on your systems and keep you fully up to date and inform you of any action needed to keep issues at a minimum and performance high.
