While “chemical wash” and “chemical overhaul” sound alike, they’re totally different.
Importantly, you need to understand the differences to pick the right one for your specific air conditioning issue.
Mainly, if you pick the wrong one, you might waste money or still be stuck with the same old problems. Therefore, in this post, we’ll discuss how to tell which service really fits your air conditioning needs.
What Aircon Chemical Wash?
A chemical wash is a deep cleaning for your air conditioner’s interior components. Notably, chemical wash is not something you do every month. Usually, it’s only recommended if it has been over a year since the last air conditioning checkup. Importantly, your aircon isn’t cooling like it used to, starts smelling weird, or leaves little puddles, it’s probably time for chemical wash.
Notably, with a chemical wash, the technician removes stubborn dirt that regular cleaning can’t touch. The technicians use special solutions, spraying them right where the buildup hides, breaking it down, and flushing it out.
Below is a breakdown of what a technician does during a chemical wash:
- They turn off the power and remove the cover.
- Remove the filter and blower.
- They spray the cleaning solution onto the evaporator coil and drain tray.
- Allows the chemicals to sit for a short while, loosening all the stuck-on stuff.
- Rinse everything out with high-pressure water.
- Unclog the drain line and put it all back together.
- Run the unit to make sure it’s working right.
What’s an Aircon Chemical Overhaul?
A chemical overhaul is the heavy-duty option. Notably, while it covers everything a chemical wash does, it procedure is much deeper. Mainly, the technician takes the whole unit apart, and cleans everything. Importantly, chemical overhaul is only recommended if your aircon has been ignored for ages, it’s acting up badly, or has sucked up a lot of construction dust.
Below is what technicians do during chemical overhaul:
- Chemical treats every part of the indoor unit.
- They take apart the outdoor condenser too.
- Scrub coils using a special cleaning agent to remove stubborn dirt.
- They clean the fan and every interior surface.
- If needed, they’ll apply a rust-resistant coating.
What are the Real Difference Between the Two?
- Scope: Chemical wash is performed mainly targeting the coils and drainage area, while chemical overhaul targets everything inside and out.
- Disassembly: With a chemical wash, most parts stay put, while chemical overhaul whole unit is dismantled.
- Outdoor Unit: A regular chemical wash skips the external coils, while an overhaul includes the outdoor condenser, ensuring the whole unit runs more efficiently.
- Time: Chemical washes are pretty quick, while chemical overhauls take much longer, sometimes twice as long, because they’re so detailed.
- Cost: Overhauls cost more because they require more labor, more time, and deeper cleaning.
- Purpose: Chemical washes remove the usual gunk, while overhauls bring neglected or heavily contaminated units back to life.
How to Choose One
When choosing one over the other, consider your aircon’s age, how often it’s been serviced, and what’s happening right now.
Mainly, pick a chemical wash if:
- You’ve taken decent care of your unit, but want a refresh.
- There’s a slight dip in performance or a musty smell.
- You’re just doing routine maintenance.
On the other hand, go for a chemical overhaul if:
- Your aircon’s cooling has tanked.
- You hear odd noises from the outdoor parts.
- It’s been exposed to a lot of dust or construction mess.
- You want to prepare an older system for heavy use.
- You’ve skipped maintenance for years.
Conclusion
If you’re not sure what your system needs, ask an experienced professional company. Notably, irrespective of whichever service you choose, don’t try this yourself. Mainly, the chemicals and high-pressure water can wreck delicate parts if you don’t know what you’re doing.
On the other hand, a trained AC technician from aircon servicing company knows which cleaners to use, how to remove all the residue, and how to put everything back together safely.
Importantly, they’ll test the unit before they leave, ensuring it’s cooling well. Also, they will ensure your air conditioner performs optimally and lasts longer.
