Questions & Answers
Frequently Asked Questions
How long does a chemical overhaul take?
It takes approximately 1.5 to 2 hours per unit due to the complete dismantling and reinstallation process.
When is a chemical overhaul necessary for an air conditioner?
A chemical overhaul is necessary when an aircon has been neglected for over a year, experiences severe recurring water leaks due to blocked rear drain pans, emits persistent foul smells, or shows significant airflow loss despite regular servicing.
Will a chemical overhaul fix ice formation on my aircon coils?
Yes. Ice forms on coils when heavy dirt isolates the aluminum fins, restricting airflow and dropping coil temperatures below freezing. A full chemical overhaul removes 100% of internal grime, restoring unrestricted airflow and stopping ice formation.
Is refrigerant gas vacuum purging required after a chemical overhaul?
Yes. Since copper pipes are disconnected during an overhaul, a vacuum pump must be connected to purge air and moisture from the lines before releasing refrigerant back into the system. This step is crucial to protect the compressor.
What warranty or assurance is provided after a chemical overhaul?
We provide a 90-day workmanship warranty covering water leaks and operational performance post-overhaul, giving you complete peace of mind that your unit will run reliably.
What exactly is a chemical overhaul, and how does it differ from a chemical wash?
A chemical wash cleans the unit while mounted on the wall. A chemical overhaul is a complete restoration process where the technician traps the refrigerant gas, disconnects the copper piping, takes the entire fan coil unit off the wall, completely disassembles every component, and submerges parts in a deep chemical bath.
