AIR CONDITIONING SYSTEMS
How often should I get my AC Serviced?
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.
One of the biggest benefits of regular AC servicing is that it allows any potential issues to be picked up early. This means that minor repairs can be made and parts replaced before a bigger issue occurs. During the AC service the Technician can also monitor the state of your ducts and coils and provide recommendations for their cleaning and maintenance. All these elements are essential to keep your air clean, your system efficient and avoid an inconvenient AC breakdown – particularly in summer when it is impossible to remain comfortable without functioning air conditioning.
How do I know how many AC units I have?
You can easily calculate the number of AC units in your property by counting the number of installed thermostats. Each thermostat will be controlling one AC unit.
Do I need to service AC units that I don’t use?
You may have multiple units in your property – some that get used regularly (for example, in the kitchen) and some that get used rarely (perhaps in the guest room). However, it is recommended that all units are serviced on a regular basis regardless of how often they are used. Aside from making it easier for you to keep track of your AC servicing, dust and dirt can still settle in an unused unit and electrical faults can still occur. We strongly recommend that you get them all serviced at the same time, so that if you are suddenly more reliant on them, they are ready to be used and are functioning optimally.
If I am in an apartment, is the AC centralized or do I need to get my own system serviced and cleaned?
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 to arrange. You should also be ensuring ducts within your apartment are regularly cleaned. If you aren’t sure, speak to your building provider to establish if you need to schedule an AC service yourself.
How often should I change my filters? How do I know if my AC even has filters?
Most filters do not need replacing often but they do benefit from regular cleaning. Almost all AC systems will have some kind of filter. These filters are necessary to remove minor particles from the air, keeping it safe and clean. Filter cleaning forms a part of most regular AC servicing visits.
Should I do anything to maintain my AC between servicing?
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.
AC USAGE
How can I reduce energy costs from ongoing AC use?
Can air conditioning control humidity?
Is it better to leave your AC running or turn it on and off as needed?
Should I leave my AC on when I go on holiday?
However, we strongly recommend that you do not leave your AC system running when you are away on holiday. With no one checking your home any issues that may develop may not be picked up and you could find yourself returning home to a disaster zone. 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.
How do I ensure my AC lasts as long as possible?
If we have multiple AC units, is it better to have them all on to cool the entire house or just in the rooms we are using?
What is the best temperature to have my AC on?
Is it a good idea to also get ceiling fans?
AC REPAIRS
What are the signs my AC isn’t working correctly?
The most obvious sign that your AC isn’t working is that the air temperature in your property isn’t cooling. If you feel warm air coming from vents or if you wake up sweating in the night it’s very likely that something isn’t right with your AC system. Strange noises and loud fans could also indicate that something within the system is faulty. In these instances you should always call out a technician so that they can evaluate the problem on your behalf. Remember, it isn’t safe to play around with AC systems yourself. The combination of water and electrics can be deadly.
What should I check before calling for an AC repair?
If you think that your system is not working correctly it is best to get a trained technician to do a thorough check. Remember that some systems may take a while to start cooling a room especially if they have been turned off for some time. If you turn on your AC and it doesn’t immediately feel cool, leave it for at least 5 minutes and check again. If you still aren’t satisfied, give our team a call.
How cold should my AC air feel?
Depending on your settings, the air coming from your system should always feel cool or neutral, not warm or hot. If you have your fan set to high but the room has already reached the set temperature, you may find that the air from the system doesn’t feel cool because it is simply circulating the existing air within the room.
How do I know it’s time for a new air conditioner?
When your AC is experiencing breakdown issues on a regular basis, there will come a point where it is more cost-effective to replace your system than to persist with replacing its parts. Dubai Municipality recommend replacing your AC units every ten years, though we believe this to be a minimum duration if proper servicing is maintained at least twice a year.
Will a new AC system save me money?
Replacing a full AC system is costly, yet selecting the right quality units and installation practices will save you money in the long run, so be sure to do your research or give us a call to discuss any queries. Many Dubai residents are currently opting to replace their old AC units in favour of energy saving inverter units that are proven to minimise DEWA bills. This is worth considering due to the relentless nature of AC usage in Dubai’s hot climate.
DUCT CLEANING
Why do ducts need cleaning? How can I tell when they need cleaning?
How can I clean my ducts myself?
What type of duct cleaning is best?
For professional duct cleaning Mantech Services uses Rotobrush equipment operated by specially trained technicians. This method loosens up more dirt and debris than many alternatives due to its accelerated spin cycle. In addition, it enables packed dirt and mould removal using a high-powered industrial vacuum at source, preventing contamination. Antibacterial fogging is one of the final steps in our duct cleaning process to kill any remaining bacteria within the ducts.
Is AC duct cleaning necessary?
When should I get my AC ducts cleaned?
How long does duct cleaning take?
Professional duct cleaning should take approximately 1.5 hrs per AC unit, depending on the length of the duct. Mantech Services uses Rotobrush equipment with powerful suction, meaning less mess and less disruption for your family. Additionally, cleaning of the area and any paint retouches are provided free of charge by Mantech Services.

Is AC coil cleaning worth it?
How much does it cost to clean AC coils?
The cost of your AC coil cleaning depends on the number of AC units you have in your home. Cost is also dependent on the ease of accessing your AC coils. Many coils in the UAE are located inside the ceiling with limited access. This can require ceiling cuts to be made to provide access before cleaning and the creation of a hatch for future access afterwards. Mantech Services coil cleaning ranges between 850 and 1450 dhs per unit and ceiling repair work is additionally 225 dhs per hour + materials (All charges + 5% VAT.) If a ceiling cut is necessary to ensure AC effectiveness, we provide seamless repair as standard.
