A new AC is only as good as its installation. A poorly fitted unit can leak water, cool badly, make noise and break down early, even if the AC itself is excellent. Use this AC installation checklist to know what to prepare, what to watch while the work is done and what to test before you pay. It is written by the team at LARC AC Repair for homes and offices in Hyderabad.
Why You Need an AC Installation Checklist
Most installation problems are not visible on day one. A drain pipe with the wrong slope, a loose joint or a badly placed outdoor unit may only show up after a few weeks as a leak, weak cooling or a high electricity bill. A simple AC installation checklist lets you check the important points while the technician is still at your home.
This guide mainly covers split ACs, which need an indoor unit, an outdoor unit and connecting pipes. Many points also apply to window ACs.
AC Installation Checklist Before the Technician Arrives
Choose the Right Spot for the Indoor Unit
Pick a wall that is high enough for the air to spread across the room, with clear space around the unit as given in the manual. Avoid placing it where cool air blows straight onto the bed or sofa, and keep it out of direct sunlight and away from heat sources.
Choose a Safe Spot for the Outdoor Unit
The outdoor unit needs fresh air to release heat. Choose a ventilated, shaded place that is easy for a technician to reach for servicing. Avoid tight corners where hot air gets trapped, and make sure the stand or bracket is strong enough to carry the unit.
Check Power and Earthing
Your AC should have a dedicated power point and a suitably rated MCB, as the manual recommends. Check that the wiring is in good condition and the earthing is proper. Weak wiring is a safety risk and can trip the AC again and again.
AC Installation Checklist During the Work
- Brackets and stand: they should be level and firmly anchored to the wall.
- Copper pipes: they should be insulated, free of kinks and as short as practical. Extra pipe length can need extra gas and cost, so agree on it before the work starts.
- Electrical connections: joints should be tight and neat, with proper earthing.
- Drain pipe: it must slope downward all the way and not sag. A wrong slope is a common cause of indoor leaks, which our water leakage repair team often sees.
- Vacuuming: the technician should remove air and moisture from the lines before opening the gas.
- Joint check: the flare joints should be checked for gas leaks. If your AC later cools weakly, read about AC gas filling.
Also make sure the technician works safely at height, using proper support. Never lean out of a window yourself to help.
Final Test Run in Your AC Installation Checklist
Do not pay until the AC has been tested properly. Ask the technician to run it for at least 15 to 20 minutes while you check the points below:
- The air turns cool and the room starts to cool down.
- The remote, modes, swing and fan speeds all respond.
- There is no rattling, scraping or heavy vibration from either unit.
- Water flows out of the drain pipe and does not drip inside.
- The outdoor fan runs and the stand is steady.
- You receive the warranty card, the bill and the installer’s contact number.
Common Installation Mistakes to Avoid
- Installing the indoor unit too close to the ceiling or a side wall, which blocks airflow.
- Using a long or badly bent pipe, which reduces cooling.
- Skipping the vacuum step before releasing gas.
- Connecting the AC to a weak or shared socket.
- Leaving the drain pipe flat or pointing upward.
- Choosing the wrong size, so check your room first and look at the star label explained on the Bureau of Energy Efficiency website.
Questions to Ask Your Installer
- What exactly does the installation charge include, such as pipe, stand, wiring and drain?
- What is the charge for extra pipe or wiring if more is needed?
- Do you test for leaks and vacuum the lines before starting the AC?
- What is the installation warranty, and who do I call if there is a problem?
If you are moving house, you will also need careful removal first. See our AC uninstallation service. After setup, book a yearly AC service to keep it running well.
AC Installation Checklist FAQs
How long does AC installation take?
A standard split AC installation usually takes a few hours, but it can take longer if extra piping, wiring or a stand has to be set up.
Where is the best place to install a split AC indoor unit?
Choose a high spot on a wall with clear space around it, away from direct sunlight and not pointing straight at the bed or sofa.
Can I install an AC myself?
It is not recommended. A split AC needs pipe work, vacuuming, electrical connections and safe work at height, so a trained technician gives a safer and longer-lasting result.
Should I test the AC before paying the installer?
Yes. Check cooling, the remote, noise and the drain during a proper test run before you make the final payment.
Do you do AC installation across Hyderabad?
Yes. LARC AC Repair serves many localities, and you can check your area on the service areas page.
