OP I know the feeling. Actually ever since the beginning of last year I started servicing my own AC units. I just paid very close attention to the guys the last three times they serviced and replicated what they did. The first time I did it on my own, I took much longer than the average time, but I got through and ever since had no issues.
I guess if you do not think you'll remember everything that you observe, maybe video the guys and rewatch video when servicing. Disassembling the units for servicing tends to be the trickiest aspect of it I guess. Nevertheless OP hope you gt

How to clean A/C evaporator coils: the basics

Evaporator coils should be checked and cleaned as needed. If the coils are prone to collecting dirt and debris easily, monthly cleaning may be required. Otherwise, you may need to clean them every three months during cooling season or annually during regularly scheduled preventive maintenance.

How to clean A/C evaporator coils: getting access

Your indoor air handling unit should have an access panel that can be removed to expose the evaporator coil. If necessary, check your A/C owner’s manual to locate the access panel and evaporator coil.

Turn the air conditioner off at the thermostat.

Remove the screws or other fasteners to loosen the access panel.

Place the panel and screws aside where they won’t get lost or separated.

How to clean A/C evaporator coils using compressed air

Light accumulations of dirt and other material can often be removed using compressed air to blow them loose from the evaporator coil.

Direct compressed air across the coil in the opposite direction of normal airflow, from the cleaner to the dirtier side.

For more stubborn pieces, place the air nozzle close to the bottom side of the debris.

If using high pressure air, direct it either at a 90-degree angle or directly through the fins. This will prevent damage to the fins.

Maintain consistent airflow across the coil. This will dislodge buildup without forcing it further into the fins and making it more difficult to remove.

Avoid blowing dust, dirt and debris into the ductwork system or into your home’s living spaces. Wear eye protection to keep the material out of your eyes. If necessary, use a shop vacuum cleaner to collect material as it is dislodged.

How to clean A/C evaporator coils using a brush
Brush cleaning can be a very effective technique for removing minor accumulations of dirt from evaporator coils. Brush cleaning allows you to avoid the use of liquids or chemicals and gives you greater control on the pressure applied to the coils and fins.

Apply the brush to the coils and sweep dirt accumulations away.

Scrub with the brush to break loose harder-to-remove material.

Avoid using wire brushes or hard-bristle brushes since they may damage the fins.

How to clean A/C evaporator coils using commercial cleaners

Several brands of commercial cleaners are available for cleaning evaporator coils. Most are a foaming type that breaks down and drains away into the unit’s drainage system. Consult with your trusted local HVAC contractor for suggestions on which cleaner would work best for your situation.

Follow instructions and precautions that accompany the product.

Spray the cleaner on the coils as directed.

Allow the foaming action to occur and wait until the foam and debris drain away.

Reapply the cleaner until the coils are clean and free of buildup.

How to clean A/C evaporator coils using mild detergents and water

In place of a commercial cleaner, you can use a mild detergent and warm water to clean the coils.

Mix warm water and a simple detergent in a spray bottle, hand sprayer or garden sprayer.

Apply the water and detergent solution to the evaporator coils.

Give the solution a few seconds to a few minutes to soak in and loosen debris. Reapply as needed.

Wipe away the loose material with a soft cloth or brush.

How to clean A/C evaporator coils: heavy-duty cleaning

Heavily soiled evaporator coils may require strong chemicals or heavy-duty cleaning techniques and equipment such as a pressure washer or steam cleaner. The process could also require revisions to your A/C system, such as removal of the coil, cutting and reattachment of refrigerant lines, restoring the vacuum in the refrigerant lines and recharging/refilling the system with refrigerant.

If your A/C evaporator coils are heavily soiled or are dirty enough to seriously affect air conditioner function, you should schedule a professional cleaning and maintenance appointment with your local HVAC contractor. Your HVAC technician can properly assess the job and will have the correct equipment, training and material to clean your evaporator coil and restore cooling system function without causing damage to the coils, fins or other components

You are right, Its not that hard. But there are tid bits you may need a qualified person to handle. Provided its something you do regularly, you may not need to call anyone.

Op will be calling me soon though.

https://www.facebook.com/ParsotanAC/

I dont mind offering some advice if he willing to make the call. Some of it is DIY and I encourage people to DIY, less damn work for me. :lol: :lol:

A classic example is San Fernando city police. The office was not cool and the units are stink. Paperwork has to go through for me to do the job. Meanwhile an officer chat a bit with me and there was an improvement as he did some of the minor stuff.

I'd strongly advise against using coil cleaner though. I have my own concoction that I use and I wash my hands with it. Most cleaners are very alkaline, if you throw it on your hands it will eat away the skin. I have seen the stuff being used and everything in the drain died after. Frog, fish, snail etc.

There have been systems I have come across that were so badly off I had to pump down and take home to scrap and clean. They were returned, reinstalled, vaccumed and valves opened back. Jobs like that start at $600.00 and the system comes back as new. Not a spot is missed. There are pictures of jobs like that I did for people on my page.

5 tonne units usually carry a high price if it was poorly maintained. Its a 3 man job some times but regular maintenance and proper maintenance can keep the cost down. You have to drop blower and drop coil to get behind it so its a bit tough. Most just wash the front coil and call it a day.

I had to do a pair for a company last year. Price as 3 times what they normally pay. Of course you know people find that cost ridicilious but I did get the job. Now they have to use one unit because its too cold. One was so badly off the coils were conmpletely clogged.
Told another place $1200.oo to do one and they said hell no, they pay $400.00 to get the "same job" done. Of course you know the person that told them to call me was not pleased because he sweating when he go to eat at the establishment.

i just eh want you to get shock or asphyxiating yourself with R-134a or burn down your house doing something that you never paid attention to before.

You wouldn't change the oil in your car without first either getting some training, or watching closely to see what the mechanic doing exactly.

leaking ac unit is mostly due to a clogged drip tray or clogged water line that goes outside,,, or if youre unit is low on gas and your coils constantly freeze over and get iced up. Cleaning a drip tray and clearing the line is easy for a DIY, but gassing your unit will require a service from your ac people.

The drain pan you mean.
They have 3.
A front, top and back. The rear is behind the unit against the wall. People who don't like to service on time usually suffer from that clogging and water running down the wall. I let them know one time, I can lift it off the wall and attempt to clean it but when men burst wall and plaster it back you don't have much flex on the copper and it may damage. Customer standing that cost to repair, not us. We can pump it down and scrap the whole thing bringing it back to new. Cost starts at $600.00.
Also, coils can get clogged from 6 for a 9 service. Some have more than one layer and it's hard to get a high pressure stream through it. You have to wash front and back so it has to come out completely.
If it's "low on refrigerant" it has a leak. Refrigerant is not lost unless that's the case. There can be instances where the system runs so long and the refrigerant contracts so much that it will read low. I met an r22 system reading 25 psi vs 68 where it should be. Looked for a leak only to realise evaporator is a block of ice. Well management has the remote now because I responded to 3 calls where "ac not working" only to meet it full of ice. The last instance I left them without cold breeze for the day.

newer units, the front drain pan cant be removed.

The back and rear drain pan shown here.

Routine servicing as done by I dont know who. The top of the coil actually sits in the back drain pan so unless you know what you doing, you gunna pay more in the long run.

The first step to cleaning your own AC is not being poohar.

If you poohar, call nervewrecker.
I call nervewrecker because I have neither the time, nor the equipment to properly service my own AC without some expensive consequences.

Well said Vexx. An AC unit can last very long once taken care of on a periodic basis. Nerve is a man don't even stop to think as for him it is second nature.

Bro find a video on YouTube and learn to service it yourself. Buy the necessary equipment and familiarize yourself with the brand you have. If you had 1 or 2 then I understand paying someone like me even though I could do it myself, but 5 , better you learn how, it's easy though once you familiarize your sell with the unit. The money you saving when one stops working that's your money to buy one.

No No No .. You are incorrect :wink:

The fan is difficult . That is a different job.

We hire a company to take down the extractor fan and that has lots soot, cobweb and sometimes a dead rat or pigeon etc.

They charge about $300 - $700 depending on the size and weight of the rat or pigeon .

You are talking about a ducted system. That's another type.
We are talking mini split.
I take it you never heff the blower assembly on an old Peake 5 tonne yet. You maybe accustomed to them baby 5 tonnes they have selling.
It's a 3 man job, two to hold it up and one to loosen the screws. Lol @ $300.00 to do that job. You looking to cross $1k because 2 additional men need to be paid. Then don't get me started on the coils that are 3 and 4 layers thick. You hit that with pressure washer from the front you just clogging it up. So good luck with it.

Not doubting it have a few vene's that know thier stuff but it have a few out here trying a thing. Some had managed to get thier hands on some equipment belonging to a friend of mine. Over $10k in tools and equip went missing.
I cleaned up mess made by many already.
I have seen vene workmanship first hand already and they take pride in their work. I know one living here with more experience than me and qualified in instrumentation and PLC. Cool soldier but he lives too far. And mankind speaks english fluent, he been here some years now.
