Sai Gon Home Repair 247’s wall-mounted AC installation and removal service

When do you need to remove or relocate an air conditioner?
You need AC removal and installation in many situations that change the space or position. Common cases:
- Moving house or office and taking the old unit along.
- Changing the unit’s position in the room to suit a new layout.
- Repairs or repainting that need the unit temporarily removed.
- Returning a rented home and removing a previously installed unit.
- Installing a newly bought unit or one given to you.
Whether removing, installing or relocating, the gas recovery and vacuuming steps decide whether the unit still cools well after reinstallation.
Should you bring the old unit when moving house?
Whether to bring the old unit or buy a new one depends on the unit’s age and the relocation cost. A few guiding principles:
- Bring it when the unit is still good, only a few years old, and the removal/installation cost is far lower than buying new.
- Consider replacing when the unit is too old, wastes power, or the removal cost plus new pipe nears the price of a standard unit.
- Consider the new position: a new spot needing longer pipe or harder access raises the cost.
An honest team will tell you clearly when a unit isn’t worth relocating, saving you from spending on a unit that soon needs replacing. A survey before moving helps you budget accurately.
Why does correct removal and installation matter?
Correct removal and installation decides whether the unit still cools well and lasts after reinstallation. The two most important steps are gas recovery when removing and vacuuming when installing.
Gas recovery (pump down): before disconnecting the pipe, the technician drives the gas into the outdoor unit by closing the valves in the right order. Done right, almost no gas is lost; careless removal that vents the gas leaves the unit short of gas and needing a top-up at installation.
Vacuuming: when reinstalling, the technician removes all air and moisture from the pipe before releasing the gas. This step is mandatory for inverter units using R32/R410A gas; skipping it makes the unit cool poorly, waste power and damage the compressor early.
This is why a unit removed and installed correctly still cools as well as before, while a careless job cools poorly even though nothing is broken — and often needs another technician to redo it from scratch.
Wall-mounted AC removal process
The removal process always recovers the gas first, never disconnecting the pipe while gas is still in the system. The basic steps:
- Check and run the unit: turn on cooling mode to prepare for gas recovery.
- Recover gas into the outdoor unit: close the discharge valve, then the suction valve in the right order to drive gas into the outdoor unit.
- Power off and disconnect the pipe: turn off, cut the power, undo the copper-pipe flare nuts and wiring.
- Remove the indoor and outdoor units: take the indoor unit off its bracket, remove the outdoor unit, coil up the copper pipe.
- Cap the pipe ends and pack: cap the pipe ends against dust and moisture; pack carefully if transporting.
Capping the pipe ends after removal is a small but important detail that keeps dust and moisture out of the system, protecting the unit at reinstallation.
Wall-mounted AC installation process
The installation process always vacuums before releasing the gas, never releasing gas into a system that still has air. The basic steps:
- Set the position and mount the bracket: choose a suitable spot, drill and fix the bracket securely.
- Fit the indoor and outdoor units: hang the indoor unit on the bracket, place the outdoor unit in an airy spot at the correct distance.
- Run copper pipe and wiring: flare the pipe, connect the flare nuts, wire per the diagram.
- Vacuum: use a vacuum pump to remove air and moisture from the pipe.
- Release gas and test: open the gas valve, check for leaks, test run and measure cooling before handover.
Where the new pipe run is longer than the old one, the technician checks and tops up gas if needed, stating the cost clearly beforehand so you aren’t surprised by extras.
Wall-mounted AC removal and installation pricing 2026
The cost depends on unit capacity, position, pipe length and any extras. Below are market reference ranges:
| Item | Reference price (VND) |
|---|---|
| Full package (remove + reinstall) wall-mounted unit | 250,000 – 500,000 |
| Removal only, wall-mounted unit | 150,000 – 250,000 |
| Installation only, wall-mounted unit | 200,000 – 350,000 |
| New copper pipe, wiring, bracket (if needed) | quoted separately by metre/material |
| Gas top-up (if low) | quoted separately by gas type |
These prices are for reference only. The actual cost depends on the condition and position and is agreed after a survey. Hard-to-reach or high positions may incur a safety-work surcharge.

Why you shouldn’t remove and install an AC yourself
Doing it yourself easily loses gas and damages the unit without the right tools and experience. Removal requires gas recovery in the right valve order; installation needs a vacuum pump and correct flaring.
Doing it yourself risks three things: venting the gas so the unit cools poorly and needs a top-up; skipping vacuuming so moisture and air enter the system and the unit fails early; and poor flaring that leaks gas later. All of these are more costly than the price of hiring a service.
So AC removal and installation should go to a team with a vacuum pump, gas gauge and experience, to keep the unit cooling well and durable.
Common mistakes from incorrect removal and installation
Many units cool markedly worse after removal and installation not because they are broken, but because of wrong technique. Common mistakes:
- Venting gas during removal: not recovering gas into the outdoor unit leaves it short and needing a top-up.
- Skipping vacuuming: air and moisture left in the pipe make the unit cool poorly, waste power and fail the compressor early.
- Poor flaring: a loose flare joint leaks gas gradually, so the unit weakens within months.
- Kinked or dented copper pipe: a dented pipe restricts gas flow and cuts performance.
- Loose bracket, poorly ventilated outdoor unit: the unit vibrates, is noisy and dissipates heat poorly.
This is why you should choose a technician who follows the correct process. One correct removal and installation keeps the unit running as before and avoids callbacks.
Why choose Sai Gon Home Repair 247?

What to prepare before the technician arrives
A few small preparations make the removal and installation faster and tidier. You should:
- Clear the area below and around the unit so the technician can work and set up a ladder.
- Cover or move furniture and electronics near the unit.
- Decide the new installation position in advance if relocating, so the technician can prepare pipe and bracket.
- Check the power outlet and whether the new outdoor-unit spot is well ventilated.
- For apartments, register the schedule and drilling/work hours with building management if required.
These preparations aren’t mandatory, but they help the technician work fast, avoid extras and minimise disruption.

Frequently asked questions
How much does wall-mounted AC removal and installation cost?
Market reference 2026: a full remove-and-reinstall package for a wall-mounted unit is about 250,000–500,000 VND depending on capacity and position; removal or installation only is cheaper. New copper pipe, wiring, bracket, wall drilling or gas top-up are quoted separately after a survey.
Does removal and installation lose gas?
If gas is recovered correctly (pump down, driving gas into the outdoor unit before disconnecting the pipe), almost no gas is lost. Careless removal that vents the gas is what causes a shortfall and a top-up at installation.
Can I remove and install a wall-mounted AC myself?
Not advisable without the tools and experience. Removal needs correct gas recovery; installation needs vacuuming and correct flaring. Doing it wrong easily loses gas, lets moisture into the system or dents the pipe, making the unit cool poorly and fail early.
How do I relocate an AC when moving house?
The technician recovers gas into the outdoor unit, removes the indoor unit, outdoor unit and copper pipe, transports them, then reinstalls at the new place: mount the bracket, run the pipe, vacuum and test run. Book ahead of moving day to avoid disruption.
How long does one unit take?
Removing a wall-mounted unit usually takes about 30–45 minutes; reinstalling about 60–90 minutes depending on position and pipe length. A full remove-and-reinstall is done within the day for a standard job.
Does installation require vacuuming?
Yes, especially inverter units using R32/R410A gas. Vacuuming removes air and moisture from the pipe before releasing the gas, helping the unit cool deeply and last. Skipping it makes it cool poorly and fail early.
Does removal and installation require a gas top-up?
Not necessarily. If gas is recovered correctly, no top-up is needed. Gas is only added when the unit was already low or the new pipe run is longer and needs more — and it’s stated beforehand.
How is wall-mounted AC removal and installation done in HCMC?
The technician comes on site, recovers the gas, removes the unit and pipe; when installing, mounts the bracket, runs the pipe, vacuums, releases gas and test runs. Sai Gon Home Repair 247 handles removal, installation and relocation of wall-mounted air conditioners at homes and offices in HCMC.
