Air Conditioner Maintenance

air conditioning maintenance midlands

An air conditioner‘s filters, coils, and fins need regular maintenance for the unit to work effectively and efficiently throughout its lifetime. Neglecting this maintenance will lead to a slow decline in the performance of the AC Unit. 

Air Conditioner Filters

The most important air conditioner maintenance‘ task to ensure its longevity is to regularly replace or clean its filters. Blocked filters stop normal airflow and reduce the system’s efficiency. With the airflow obstructed, any air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Swapping out a dirty, clogged filter with a clean one will lower your air conditioner’s energy consumption by approximately 5% to 15%.

Should Your Air Conditioning Unit Be Covered in Winter?

Your air conditioning unit should not be covered during winter – or, for that matter, any other time of seasonal year.

It isn’t important to cover your outdoor air conditioning unit, even in the winter time. All external HVAC equipment is specially crafted to withstand harsh weather conditions and extreme temperatures from sweltering summers to biting winters.

However, if you live in an area that’s partial to hail you may want to cover your AC Unit – especially if there is an oncoming storm. Also, if you live in an area that sees blizzards, it is important to keep excess snow out of your AC Unit.

If you do need to cover your external AC Unit, one way of doing it is to use a large sheet of tarp and securing that with rope and duct tape.

Alternatively, you could purchase an air conditioner cover, which are relatively cheap!

How To: Prevent AC Unit Faults in Winter

There are  a number things that can be done when taking precautions during the winter, so to prevent problems.

Ensure that your keep your units free from obstruction and make sure that your system doesn’t have to work harder than necessary – this can be applied to both indoor and outdoor units.

Similarly, ensure that nothing is blocking indoor vents or air discharge points enabling your system to run as smoothly as possible.

You will want to set your controllers to a reasonable temperature, keeping in mind the outdoor conditions. For an office, 23 degrees celsius is a sensible temperature, whereas 30 degrees celsius which is a common finding can put strain on the unit.

Summer and your air conditioning unit

Getting your air conditioning unit ready for summer couldn’t be simpler with BMS Aircon’s tips!

Letting your AC Unit sit idle for a number of months will inevitably lead to it collecting dirt, dust and debris which could affect its performance when you need a cool down in the heat up ahead.

Clean/replace filters

Your initial step is to clean your filters or replace them, which should be reviewed twice, annually. Failure to do this will lead to a restricted air flow which will reduce its efficiency.

Clean condenser coils

Your central air conditioners’ condenser coil will typically be located outdoors. If debris has gotten inside the unit, it is likely that the coils will be clogged with dirt. To clean the coils, the top and side panels will need to be removed, then using a refrigerator coil brush or a soft brush on a vacuum, gently clean the coils from the outside of the unit. Use the vacuum to clean the insides of the coils.

Clear debris

Scoop out any debris and leaves from the base of the condenser and, if applicable, ensure the drain isn’t blocked.

Check coolant lines

Refrigerant tubes or pipes will typically have a roam coolant line insulation covering them to prevent the loss of energy. If there are any frayed areas, replace them by installing foam insulation sleeves, or wrap the lines with a foam insulation tape.


Ensure that you test your unit once it has fully dried and then turn off the power to the condenser back by turning the thermostat in your home off, then turning the power at both the main panel and disconnect box on, lastly, switch your thermostat to cool.

Saving Energy When Using Air Conditioning

As the weather eventually becomes warmer, using your air conditioning unit will be necessary.

In order for you to save energy while you’ll cooling off, we’ve listed a number of tips below for you to follow.

Night-time – In the late hours of the day, you will not require the AC Unit to work at full capacity – turn it down so it will be running less while you are sleeping.

Portable units and windows – Another great way to save energy is to invest in a portable cooler that will cool the room you are occupying. They use up to 50% less energy than a regular AC Unit.

Have your unit serviced – On some occasions, a quick maintenance check could be the only thing your AC Unit requires, however, many will benefit from a thorough cleaning.

Furniture rearrangement – Furniture placement actually plays a big role in potentially saving energy with air conditioning. If furniture proves to be an obstruction to any air conditioning vents, the back of a settee could be getting cooled rather than yourself.

78° – Running your AC Unit oat 78 degrees is a suitable level, similar to that of a car on cruise control. There is also the option of turning it another 5 degrees lower to save energy.

Home alone – When you are not home, attempt to turn the AC Unit to 85 with any windows and drapes securely shut. It may be warm when you return, however, the blinds/drapes will have kept out the sun as well as the heat not being so considerable thus the unit won’t have to work as hard to cool the air.

Use a fan – With air conditioning units being the go to, we are forgetting that fans also do a wonderful job of keeping you cool. Using them to circulate the cool air means that you will not require too much being pumped into the room, not only that but having them as a backup is a great idea as they use left energy!

If you are hiring an air conditioning contractor, it may fair well to follow the below advice:

– Prior to doing anything, check the warranty on your current air conditioning unit to determine whether any repairs, replacements or tune-ups
– Arrange for annual maintenance on your AC Unit with a qualified technician. This will entail checking the airflow over the coil, testing for the correct fluid level, know as the refrigerant, reviewing the combustion process and ensuring proper airflow to each room
– Research the company you have hired, their work history and if there have been any complaints
– Similarly, check licensing by asking to see a copy of the contractor’s license and insurance before work stats
– Compare at least three estimates you have acquired before choosing a contractor

Buying an AC Unit

Air conditioning is becoming a common feature in offices and shops, leading to the increase of AC units sought after for homes.

What comes into question is which air conditioner should be bought. There are a number of factors that come into play with choosing the right AC Unit – there are essentially two main types of air conditioners available; single-unit models that are portable and will need to be vented through a window or door, and split-unit models that are permanently fixed to a wall.

Single-unit model

A single-unit or portable air conditioner, will often be easier to install, be a fairly cheap fix for cooling your home and allows the hot air to vent out through a hose, allowing it to be moved from room to room.
However, there are disadvantages that can become apparent such as venting the hose through an open window could potentially pose a security risk; portable air conditioners are not as effective at cooling compared to split-unit models – they will quickly get hot and leak heat back into the room; some models can be heavy, so ensure your chosen unit isn’t too heavy for you to lift comfortably and that the hand-holds are easy to grip.

Split-unit model

The advantages of acquiring a split-unit air conditioner come as follows: ideal for a room that often becomes too hot, a secure way of air conditioning your home – no need to leave windows open, quieter and more efficient that single-unit models, along with being more powerful than a single unit.
Among advantages come disadvantages such as the cost, it will be a larger amount than a single-unit model and a split-unit model will need to be mounted on an outside wall and may require a professional to install it.

Your AC unit

Central AC units are effective at cooling a home efficiently, providing that much-needed relief from that stuffy heat, come Spring/Summer time.

Although, your AC unit will only work well if the parts are kept clean and in a functional condition.
You will need to perform routine maintenance on your air conditioner so to keep the operating sufficiently.

Dirty filters will rob air flow and decrease the unit’s performance. Along with dirty filters, another energy waster is a dirty condenser coil.
If your AC unit is outside, it will likely collect the dirt the wind is blowing, thus the condenser coil becoming dirty which will not allow the sufficient airflow through the coil, therefore the refrigerant won’t be cooled as quickly, leading to a low efficiency.

Fan blades on the condenser fan or the squirrel cage fan inside that are damaged or unclean will eventually begin to vibrate and restrict the air flow.
Damaged or bent blades are what causes the vibration and will shorten the life of your motor. Build up of dirt and grime on the fan blades can also cause the vibration and restrict the air flow.

To see to these issues, your initial step would be to turn off the power to the AC unit and the outside condenser. You can then proceed to pick apart the condenser for a thorough clean.
To clean the coils, use a hose with a spray attachment and rinse.
When cleaning a blower fan, it is advised to call a professional to handle the job as they will be skilled in this area and have more expertise about the maintenance.
