AIR CONDITIONING SYSTEMS
For your air conditioning to work efficiently, it must be able to transfer heat from inside your home to the outside effectively. A coating of dirt, dust and other debris on the A/C coils can prevent this, by insulating the coils from the surrounding air and reducing the efficiency of the heat transfer process. To minimize energy usage and reduce utility costs, the A/C filters should be cleaned once in 3-4 months, coils and ducts should be cleaned at least once a year.
Experts agree that ideally AC units should be serviced every 3-4 months to maintain cleanliness and efficiency. Drain lines and drip trays build up and need to be cleaned in order to avoid leaks. Electrics also need to be checked and filters should be cleaned to ensure that the air is as clean as possible

You can easily calculate the number of AC units in your property by counting the number of AC controllers. Each AC controller/thermostat will be controlling one AC unit.
If you notice poor cooling, any odour and unusual sounds, your AC should be serviced and checked. Kindly book a free inspection now.
You may have some AC units in your property that you rarely use (i.e. guest bedroom). However, it is important to get all AC units serviced because dust, dirt, and mold can still settle in unused units and electrical faults can also occur. We recommend that you service all AC units at the same time so that when you do start using them, they work effectively and efficiently.
In most cases, the AC units for your apartment will need to be separately serviced from the others in the building and this is likely to be your responsibility or your owner responsibility in case you are a tenant. You should also be ensuring ducts within your apartment are regularly cleaned at least one time a year. If you aren’t sure, speak to your building provider to establish if you need to schedule your AC servicing yourself.
Considering the air filter has such an important job, it’s essential to keep your air filter clean. But how often do you really need to change the air filter in your HVAC system? Learn about factors that impact how often you should replace your air conditioner’s air filter.
How often you should change your air filters depends on how frequently you use your house. For a seldom used vacation home, you could get away with changing your filters once a year. However, for a typical suburban home, you probably want to change your filters at least every 90 days depending on the circumstances.
The number of people and pets in your home will impact your home’s air quality. A single person without pets will need to replace their air filters far less frequently than a household with kids and multiple pets.
Pets can add excessive dander to your home’s air and can bring more particulates like dust, pollen, and dirt from outdoors into your home. If you have at least one cat or dog, you should change your filters at least every 60 days.
The more pets you have, the more frequently you’ll need to change the filter. For every pet you have in your home, you should expect to get 30 fewer days of performance from your air filter though. If you have multiple pets, then change your filters once a month.
A final factor to consider relates to the efficiency of your air filter. More efficient air filters are designed to trap more particles and last for longer periods of time. It is wise to pay attention the filter manufacturer’s recommendations regarding replacement and make adjustments based on your usage and how many occupants are in the home. In most cases in Dubai building, we are dealing with Aluminium filter who require only cleaning unless its really damage or very rusty. However fiberglass filter are cheaper but more likely to be change regularly depending on the usage.
In Dubai, you may need to change your air filters more frequently because of the presence of moisture, mold, dust, and other allergens. If you have allergies and are sensitive to contaminants in the air, then it’s a good idea to change your air filters regularly. This helps you and your guests and fellow house dwellers breathe and rest easy in the days to come. Cleaner air means better health for everyone at the end of the day.
No. Aside from minimising running hours by keeping your system on Auto and turning off rooms as required, your system shouldn’t require any special attention.
Regular servicing needs to be carried out, but this should always be done by professional technicians since it requires potentially dangerous electrical work and climbing onto ceilings and roofs.
However, you should minimize dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris.
Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet (0.6 meters) allow for adequate airflow around the condenser.
AC DUCT AND COILS
Air ducts, or HVAC ductwork, or AC ducts, are conduits that supply warm or cool air to heat, ventilate, and cool each room. Air ducts are connected to the HVAC unit which filters then heats or cools your home’s air before sending it off.
Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility.
Duct cleaning, generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans, fan motor and fan housing, and the air handling unit housing.
You should consider having the air ducts in your home cleaned if:
– There is substantial visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system.
– Ducts are infested with vermin, e.g. (rodents or insects).
– Ducts are clogged with excessive amounts of dust and debris and/or particles are released into your home.
There are many benefits to having the HVAC ducts cleaned, and these include:
Allergens are removed
The AC ducts are breeding grounds for harmful bacteria and dangerous contaminants. Getting an AC cleaning done at least once every year will remove such allergens. If this is not done, then it may cause serious respiratory issues and breathing trouble.
Gets rid of odours and smells
We know that all homes have a distinct smell to it, and it is not always pleasing. The smell of food, tobacco, mold, etc. can ruin the impression you make on your guests. Regular duct cleaning can remove any unpleasant odours in the air and make your house smell fresh.
Improves the quality of air
You may be breathing in dust and bacteria without knowing it at your house or place of work. This can make you seriously unhealthy and cause discomfort, coughing and even results in dangerous respiratory diseases.
Better living space for your family
The dust in an air duct settles and starts to disperse in the air when the air conditioning powers up. Your living space is affected by this dust and elders, or children can quickly be affected by even a little bit of dust.
However, the team you decide on must be NADCA certified which ensures that they follow the correct standards and procedures and are qualified to conduct the work. You can always rely on Techtiq for superior air duct cleaning services in the Dubai.
The evaporator coil is the component in your AC system that absorbs the heat from the air inside your home. It is often either attached to your furnace or located on the inside of your air handler. It works with a condenser coil to complete the heat exchange process that produces cool air.
Due to the tight spacing between the coil fins, surface moisture from the cooling process, and the amount of air that flows across them, dirt, dust, debris and other pollutants can build up on the coil surfaces.
It’s important to keep the AC coils clean so that heat can exchange efficiently through the coils without being blocked by dirt and debris. A lack of routine maintenance on the coils can lead to higher energy bills and consumption or an overheating AC system.
AC USAGE
ACs are a big part of our lives in Dubai, and they contribute to a huge chunk of our DEWA bill.
Simple measures such as heat blocking blinds and curtains could help to block out the heat making it easier for your AC to maintain comfortable temperatures. If it doesn’t need to work so hard it will use less energy, reducing your energy bills. Also, Smart thermostats that include climate control and eco modes will help to ensure your system is running as efficiently as possible.
If you don’t have a smart thermostat, you can still adjust your temperature regularly to ensure efficiency. Make sure fans are set to “auto” so that they shift to low or turn off entirely once comfortable
temperatures are reached. During the hotter months increasing thermostats to around 25/26 when you are not at home will help to sustain humidity whilst minimizing cost.
It is also important to have your AC regularly serviced to ensure that your system is running efficiently. Any broken parts, blocked filters etc could be causing inefficiencies that make your electricity bill shoot up.
Too much moisture in the air makes you hot, uncomfortable, and can have a damaging effect on your home. Too much humidity causes mould growth and can create condensation in your walls. This leads to structural damage and wood rot.
On the other hand too, much humidity is also bad for you. It can lead to respiratory problems, allergy flare-ups, and sleep interruptions.
Your air conditioner naturally helps reduce indoor humidity because it’s introducing cooler air while removing warm, humid air. If your Ac is running correctly and you are still experiencing high levels of moisture or humidity indoors, then there might be mechanical issues causing inefficiencies in your AC system. Call us to book an Ac servicing today.
Leaving your air conditioner on is actually more efficient than frequently turning it on and off. Having your AC on also allows you to better control humidity in your home throughout the day. The lower the humidity in a home, the more comfortable it feels during hot weather.
However, trying to cool your home later, means the AC will have to run for longer before cycling off and this can mean significant energy consumption.
When it’s hot outside, you will quickly learn that turning off the AC is not the best thing to do. You will return to a hot home, and it will take much longer to restore comfortable temperatures. This can take a real toll on comfort and even health.
Depending on the length of your trip, it may be more beneficial to leave your AC on for the duration of your vacation instead of shutting it off. If a constant temperature is maintained, this will often allow your HVAC system to utilize less energy instead of having to account for extreme highs and lows in temperature. To help keep costs down even more, close your curtains and check for any openings in windows/doors that could let out cool air, prior to your departure.
For vacations that are going to last longer than a week, it might make more sense to shut the AC off for the duration of your trip, to avoid unnecessary cooling in your home while you’re away. Also Blocked drains, gas leaks and electrical fires can all occur if AC systems are not regularly checked, and these can cause untold damage to your home.
No matter what brand or model of air conditioner you have in your home, regular Ac servicing will improve reliability and durability of your cooling systems. So, it’s very important to have your Ac units being looked after by knowledgeable experts.
Regular servicing means that parts are replaced early, and the system is clean and efficient, thus avoiding any unnecessary pressure on key parts of your AC system that could result in expensive damage.
Multiple studies have assessed indoor temperature and work productivity. The conclusion is while in general people should set their AC to 22-25°C while working from home for productivity, it’s a setting of 22°C that facilitates the most productive outputs. 24°C is the optimal standard temperature for human occupancy and energy efficiency.
A slightly cooler temperature of 22°C effectively aids the highest level of work productivity. However uninterrupted sleep is better achieved in cooler temperatures of 20°C.
Ceiling fans don’t reduce the temperature of a room. However, the air they circulate can make a room feel three to four degrees cooler. By setting the thermostat a little higher to take advantage of the fan’s air circulation, you can save up 30 to 40 percent on your utility bill.
AC REPAIRS
– Weak or Warm Air Flow from the Vent
Central air conditioning works by taking warm air, transferring it to outside your home, and then blowing cooled air throughout a space. That’s an extreme simplification of a complex process, but it can help us understand why weak airflow from a cooling vent can be a sign of several problems with an AC unit.
– The Air Conditioner is Making Strange Noises
Some air conditioners are quieter than others, and older HVAC systems can be considerably louder than newer ones. But if you begin hearing new, strange noises — and it’s not some edgy new music from your teenager’s bedroom — then it could be a warning sign that your air conditioner is not working properly.
– There is Moisture or Leakage
If you see leaks around your air conditioning system, then you’ve got a problem to address. In some cases, it’s not serious. If water is pooling or dripping near your AC unit, it may not be a matter of the air conditioner not working, but that could be that the drain tube for condensation is blocked. An AC tech can unclog the tube and treat it with a chemical to prevent rust or mold growth that can block the tube and cause flooding.
-There Are Strange odours when the Air Conditioner is Running
Any kind of strange smell is not welcome in your home, and if your AC system is to blame, it’s a stinky call to action.
– Check your power supply
Believe it or not, we get a few calls like these during the year from homeowners. Our technicians have shown up, only to find out that the house doesn’t have power! This is both embarrassing and upsetting when you have to foot the bill for the AC service repair call.
– Check your Ac filter
The airflow to your unit is very important and air filters should be cleaned when they are dirty. If they’re not checked regularly, the restriction of air could cause the A/C unit to malfunction.
– Check Your thermostat
Sometimes the Ac isn’t working just because the thermostat is on a bad setting. In this case kindly adjust it on the temperature of your convenience. If the thermostat display doesn’t light up, it might be the batteries defects.
– Check the circuit braker.
Having a look to your circuit braker might save you time, energy, and money. Sometimes the Ac isn’t working because the AC button on the circuit breaker drop off.
Well maintained AC units can last for a long time and regular servicing and replacing parts will typically keep your system running effectively and efficiently. Replacing a full AC system is a costly job and would only be considered if parts were no longer available or your AC unit is creating significant costs due to regular part replacement. However, theses are signs that your Ac Unit might be replaced.
Lack of Cool Air & Limited Airflow
This is probably the most obvious sign that your AC is experiencing issues. If you turn on the unit and the air doesn’t come out cold within a few minutes, there’s a good chance that it’s not performing properly. The issue could also be a result of clogs in your piping/ductwork, which restrict airflow and will not resolve on their own. No matter what the cause, a lack of air flow is a sure-fire sign that you have a problem which must be dealt with.
Build-up of Moisture
All AC units will create moisture to some extent, but those which are functioning properly should be able to handle it without issue. When moisture is present or leakage is occurring around the AC, it could be that you have a refrigerant leak on your hands. This will not only cause the system to underperform, but it also poses a serious health risk to you and your family. Even if it’s just water that’s building up, allowing the problem to persist can creating an undesirable breeding ground for mold.
Strange Sounds
Have you noticed that your AC is noisier than it used to be? The presence of strange sounds such as grinding, squeaking or chattering is never normal and should not be taken as a typical sign of aging. Most AC units are supposed to operate at a noise level that is barely detectable, so if your cooling system is drawing attention to itself, you know it’s time to upgrade to new equipment.
Foul Smells
In the same way that noticeable sounds typically indicate a problem with heating and cooling systems, so too do strange smells. Your AC should be putting out clean, neutral-smelling air, but this isn’t always the case when problems exist. A smokey or burning smell can indicate serious problems and requires immediate attention.
High Energy Bills
If your energy bills have been through the roof as of late, it could have something to do with a cooling system that is simply working too hard to get the job done. Even if the home isn’t properly cooled, your AC may be running up your monthly energy bills to a noticeable extent. Upgrade to new equipment, and you can reduce your bills for years to come.
Installing a new air conditioning system is a big investment but changing your AC unit can lower your energy consumption significantly and save you money on your electricity bill. However most central air conditioning units last about 20 years. At 12 years old, your air conditioning unit is passing its mid-life point. So, if your Unit is not that old referring to experts for an efficient repairing might be the right thing to do.
