They will dismantle the main parts, such as, fan coils, water trays, and air filters and wash those with a chemical-based solution.
This helps to wash away the dust and dirt accumulated on the internal parts, thereby increasing the cooling efficiency of your system.
Ideally, you should get a chemical wash of your air conditioner done twice a year. That way, you can extend the lifespan of your system and improve the indoor air quality.
Chemical cleaning helps reduce corrosion, and control or eliminate molds. This method of cleaning is usually used as a preventive measure and helps an air conditioner function normally for years.
Unlike chemical cleaning, aircon overhaul is used as a method of aircon servicing or repairs. If you notice your air conditioner not cooling enough or making a loud noise or leaking water or has stopped working completely, you may need to go for an overhaul.
In this process, each part of the system is dismantled and then cleaned, repaired or replaced. HVAC professionals can tell you whether your machine needs a complete overhaul or just chemical cleaning would suffice.
If you are facing any issues with the performance of your air conditioner, you should contact an experienced technical immediately. Delay in doing the necessary servicing can further aggravate the problem.
In general, overhaul helps deal with the following issues.
Blockage of the vents due to accumulation of dust particles or toxic gunk
Blockage of drain pipes causing water to overflow
Severe damage to the evaporator coils
Fan bearings not working properly
Faulty or damaged air filters
After dismantling the parts, each of those is checked thoroughly. Depending on the condition of the parts, some of them may need to be repaired, while others may require complete replacement.
Once you get an aircon overhaul done, you can expect your system to run like new all over again.
