Your AC stops cooling. You call a technician. They appear three days afterwards, and charge you a little buck, and say that the filter was not dirty. Sound familiar? The thing is this: much of air conditioner maintenance is the kind of work that you can do with your own hands, with no tools, belt or trade-qualified whatsoever.
A majority of house owners do not understand the extent to which they can go by themselves. Not performing routine air conditioner maintenance not only equates to a warmer house, but it also equates to increased energy bills, decreased life span of the unit and increased cost of repair that keeps increasing at an alarming rate. The good news? We, AC Maintenance UAE, have compiled all the information that you require to know about the maintainability of your unit without necessarily picking up the phone each time.
In this blog, you will have a clear and open discussion on what you can do on your own, what you really need to do it and what is the point you should call a professional. No fluff. Simple common-sense measures that will save you money and time.
AC Maintenance Tools You Need Before Getting Started
You don’t need to have a toolbox of equipment. Even simple AC maintenance tools will allow accomplishing the majority of DIY work in a safe and efficient manner, and most of them are extremely inexpensive.
Before you make contact with anything, we had better speak of tools. The appearance without being ready is the way people are going to do more harm than the initial issue. The correct equipment simplifies the work, makes it less risky and, to be honest, much less discouraging.
Basic Tools Every Homeowner Should Have
These are the essentials. You do not want anything fancy, but good:
- Screwdriver set: Flathead and Phillips, to get the vent covers and panels off.
- Fin comb: folds bent condenser fins and does not break the coils.
- Coil cleaner spray: removes dirt on the evaporator coils and condenser coils.
- Wet/ dry Vacuum: empties the condensate drain line in a hurry.
- Soft bristle brush: does not scratch delicate surfaces, loosens dust.
- Replacement filters, you should have one of them ready.
That will really cover 80 per cent of the routine maintenance. Store them in one place where you can reach them; you will need them more than you imagine.
Safety Gear You Should Never Skip
This section is skipped far too frequently. A small amount of pre-work can eliminate an actual injury:
- Safety goggles: coat of coil cleaner and other debris is no laughing matter.
- Disposable gloves: cover the skin with cleaning chemicals.
- Dust masks and N95S, in particular, are important, particularly when the unit has not been cleaned recently.
- Non-conductive shoes: never forget to switch off the power, but do not ignore this.
It is not optional to switch off the power at the breaker before starting. It is the initial step, every time. No exceptions.
Air Conditioner Maintenance Checklist for Homeowners
There is an appropriate AC maintenance checklist that comes in the form of a checklist to divide the tasks on a monthly, seasonal, and annual basis. This organisation makes sure that nothing is left to chance and your unit is effectively running throughout the year.
To homeowners, one of the biggest mistakes they commit is regarding maintenance as an annual event. Some duties are actually worth the extra consideration. Its frequency division helps to make it manageable and prevent a small problem from becoming a costly one.
Monthly Maintenance Tasks
These are short tests that can be carried out within 10-15 minutes and significantly change things in the long run:
- Inspect and wash or change the air filter.
- Clean up any debris that is visible around the outside unit, leaves, dirt, and overgrown plants.
- Also, ensure that vents in the house are open and not blocked.
- Note atypical noises during unit start-up.
In fact, the filter by itself causes a massive percentage of AC issues. Do that, in case you do nothing on this list.
Seasonal Maintenance Tasks
You have two good windows, before summer, before winter, to do more serious air conditioner maintenance. At this point, you go the extra mile:
- Wash the coils of the condenser on the outside unit.
- Flush the drain line condensate.
- Check the evaporator coils to find out whether they are dusty or mouldy.
- Make sure that the unit is stable on the pad level with the unit. It can be moved around by means of vibration.
- Check the thermostat and ensure that it is working properly.
Annual Maintenance Tasks
Have a complete system review every year. Here you get the things which have been gradually growing the whole year:
- Check refrigerant line insulation for cracks or wear out.
- Ensure that all electrical connections are tight (do not touch wiring)
- Clean the fan blades of the blower(where they are available).
- Check the general success of the cooling. Is it cooling the same way it did before?
In case something is not right in your annual check, then it is time to invite in a professional. It is better to address it at the early stages, rather than experience a total collapse during the summer.
Air Conditioner Filter Replacement Step by Step
One of the easiest and most effective maintenance procedures that you can perform on your own is this one: air conditioner filter replacement. When your filter is clogged, it limits the air flow, makes the system work harder and consumes your energy bills at a rapid rate.
One of the activities on this whole list that gives the most bang-for-buck is the replacement of the filter. Still, it is the one that is forgotten most by people until the time the unit begins to fall behind.
How Often Should You Replace the Filter
It requires a few things – the type of filter, the frequency of running of the unit, and your home conditions:
- Basic fibreglass filters once every 30 days.
- Pleated filters every 60 to 90 days
- Pet homes or allergy patients require replacement of all types of filters every 3045 days.
- Unoccupied apartments or seldom-used vacation homes should be checked every 6 months.
It is not a matter to go by the calendar. Take out the filter and examine it. When it is apparent that it is grey, dust-filled, or blocked, change it, regardless of the time of last change.
How to Choose the Right Filter for Your Unit
Check the MERV rating. Minimum Efficiency Reporting Value is known as MERV, and it measures how fine the mesh of the filter is. MERV 8-11 is the overlay range, and it is a good solution to most houses, as it stops dust, pollen and other typical allergens without impairing airflow to a crawl. Exceeding the system (MERV 13+) that it is not designed to can actually overwork the unit.
Also, look at the physical size; it is normally printed on the side of the filter you have. Make a list, capture a photograph and then get to the shop. This may not seem like any secret, but you may be surprised to know that a lot of people make assumptions, and most of them are not always accurate.
Air Conditioner Unit Maintenance Tasks You Can Do Yourself
The majority of air conditioner unit maintenance, such as cleaning the coil, drain line cleaning, and vent cleaning, is something that can be done by homeowners. It only takes the proper procedure and time.
Here is where it gets a little more practical. However, that should not stop you, and these are not complicated tasks as long as you know what you are doing. We, AC Maintenance UAE suggests that this should be done no less than once a season.
Cleaning the Condenser Coils
Your outdoor unit has the condenser coils, which expel the heat out of the refrigerant. When they are covered with dust and dirt, the entire system is forced to be more laborious. Here’s how to clean them:
- Switch off the power at the breaker, not the thermostat only.
- Take the outer casing off or the grille (several screws normally)
- With a soft brush, take away the loose debris from the fins.
- Use coil cleaner spray and allow the product to dry after 5-10 minutes.
- Spray, do not use a high-pressure sprinkler.
- Allow to dry completely, and then re-energise.
Make sure you do not bend over the fins. They’re delicate. When you bend a few, then it is the business of the fin comb.
Clearing the Condensate Drain Line
The condensate drain line eliminates moisture drawn in the air. When it becomes clogged, and it will become clogged sooner or later, the water retards and can result in actual damage. The time of clearing is approximately 10 minutes:
- Find the drain line, typically a white PVC pipe, around the inside unit.
- Locate the point of entry (a little cap or T-shaped opening)
- Put a cup of distilled white vinegar in line.
- Allow 30 minutes and empty using clean water.
- The outdoor end has a wet/dry vacuum, which can be used to remove any stubborn blockage.
Repeat this every 3 months, and you will probably never have to deal with a clogged drain ever again. It is one of those jobs that would be totally painless as long as they are done on a regular basis.
Cleaning the Evaporator Coils
The unit has the evaporator coils that are typically located behind the air handler panel. They absorb the heat from your indoor air, and therefore, when they are dirty, cooling efficiency is significantly reduced. Apply no rinse coil cleaner spray: spray it, allowing it to foam and drip itself. No rinsing needed.
When you notice that the coils are covered with mould, that is even bigger. Mop the floors that you can, but you should think about getting a professional to do a more thorough job.
Checking and Cleaning the Air Vents
Clogged or contaminated vents also limit airflow in your house, as well as imbalances the load on the system. It is necessary to wipe the vent covers with warm, soapy water once a season. When they are away, a vacuum cleaner with a brush attachment should be used to get rid of dust in the duct opening.
Checking Refrigerant Lines for Insulation
The refrigerant lines are made between the indoor and outside units. Foam insulation should be covered to them. With time, the insulation corrodes, cracks or even falls off. Test the state during your yearly “AC-tune up. When the insulation is ragged, it can be easily fixed with the foam pipe wrap that can be found in any hardware store.
Stop in case you notice the copper lines being frosty or icy. That’s not a DIY fix. This is an indication of a refrigerant problem and requires an authorised technician.
When Should You Stop DIY and Call a Professional
Look, DIY has real limits. And learning when you have reached those limits is just as important as learning how to clean a coil. The following are the obvious cases when you drop the tools and call someone:
- Refrigerant is leaking or is frozen over the lines – refrigerant handling should be qualified.
- There is grinding, banging or rattling inside the unit.
- The unit operates continuously, and it does not cool the area.
- Burning smell or any scorch marks can be detected electrically or seen anywhere on the unit.
- Damage or mould surrounding the indoor unit was caused by water.
- The breaker continues to trip during the operation of the AC.
None of this is going to be a case where a YouTube tutorial would assist. It is at these times that you cut corners on a professional phone call and pay much more. AC Maintenance UAE will always suggest being on the safe side of the road when unsure; even a check-up is an affordable alternative to replacement.
At that, the entire idea of routine air conditioner maintenance is that you will hardly find yourself in such scenarios. When you keep the filters, coils, and drain lines, the major issues will not manifest.
