Most of us can’t imagine our lives without air-conditioners, both at home and at work. They cool the rooms down during scorching days and warm up the place when it’s freezing outside. Because they are simple to operate, many people simply believe that once installed, air-conditioners will work perfectly well forever.

Unfortunately, that is not the case. Just like any other appliance, an air-conditioner requires regular maintenance, so that it can continue to provide reliable service for many years. This job is best left to the experts, but each homeowner should know what needs to be done, because there are some things that don’t require professional assistance. Let’s take a look at the most important things that need to be done as part of the annual maintenance process.

Replacing the filter

There’s no universal answer to the question “How often should I replace my filter?”, because it depends on many factors, such as the number of working hours, the type of work, the state of the A/C unit, etc. People tend to replace the filters in their central air systems every few months, but in case they haven’t done that in a while, the annual maintenance time is when they really have to do it. Writing down the date of the last filter replacement and setting a reminder for the next one is a very smart thing to do, since this chore won’t slip your mind then.


Cleaning the vents

This is something that should under no circumstances be done only once a year, but you should always use the opportunity to clean your vents when you have a regular annual inspection of the system. If your venting system is complicated, you may wish to let the professionals deal with it. Otherwise, roll up your sleeves and clean your air ducts and vents thoroughly, if you wish your air-conditioner to work properly.

Unblocking the system

It happens quite often that various things end up in your outdoor unit, which draws air into the system. Filth, dust, leaves and similar objects build up easily and make it impossible for your A/C unit to work properly. Also, if you used your A/C closet to store some garden furniture or similar items that you currently don’t need, now is the time to remove them, so that you keep the system unobstructed.

Checking Freon levels

Ideally, the Freon in your A/C system should never need to be replaced, since the air-conditioner doesn’t consume Freon coolant. However, even the tiniest of leaks, which often appear in older models, or any other kind of abnormality requires professional attention because it is important to detect problems early on, before they escalate into expensive repairs.


General inspections

Since modern HVAC systems are much more sophisticated than older ones, they require more detailed attention. For example, the electrical controls and coils need to be inspected regularly, which is probably something most of us can’t do without professional help. Also, calibrating the thermostat is another action that should be done during the annual maintenance.

Like in so many aspects of life, prevention is much cheaper and less painful than treatment or replacement when it comes to your HVAC system, too. Routine servicing and maintenance are vital for extending the life span of these systems, which is why you should make sure that you have experts perform such tasks regularly. For example, these air conditioning pros operating in Chatswood have a proven record of accomplishment, making sure that all projects are done with utmost expertise using quality tools and materials while offering their clients full support and accessibility.

Also, if you need to replace a certain part, make sure that you buy the best quality one, because suspiciously cheap parts are not very likely to last long. Similarly, you should only entrust licenced professionals with the task of installing and maintaining your HVAC system, because only in that case can you expect it to function properly and last long enough to justify the investment in it.
