Installing a new air conditioner is an important step towards creating a cooler and more comfortable home or workplace. However, successful installation involves more than choosing an aircon and booking a technician.
Preparing the room, checking electrical requirements and understanding where the unit will be installed can help prevent delays, unexpected expenses and installation problems.
Whether you live in a house, apartment or condominium in Cebu, a little preparation before installation day can make the entire process easier.
This aircon installation checklist explains what homeowners, tenants and business owners should prepare before a technician arrives, including room access, aircon placement, electrical considerations and important questions to ask.
1. Confirm the Right Aircon Size for Your Room
Before scheduling installation, make sure your air conditioner has enough cooling capacity for the space.
Air conditioners are commonly classified by horsepower (HP) in the Philippines. Choosing the correct size helps maintain comfortable indoor temperatures without unnecessary energy consumption.
General Aircon Horsepower Guide
| Room Size | Suggested Aircon Capacity | Common Application |
|---|---|---|
| 6–11 sqm | 0.5 HP | Small bedroom |
| 12–17 sqm | 0.75 HP | Standard bedroom |
| 18–22 sqm | 1.0 HP | Larger bedroom or home office |
| 23–27 sqm | 1.5 HP | Studio apartment or living area |
| 28–40 sqm | 2.0 HP | Larger room or open-plan space |
These are approximate starting points rather than fixed requirements. Sunlight exposure, insulation, ceiling height, occupancy and heat-producing appliances can affect the capacity needed.
For rooms with large windows or strong afternoon sunlight, consider asking a technician to assess the cooling requirements before purchasing your aircon.

2. Decide Where the Indoor Aircon Unit Should Be Installed
Choosing a suitable location for the indoor unit is one of the most important parts of installation planning.
For split-type air conditioners, the indoor unit should be positioned where it can distribute cool air throughout the room while remaining accessible for maintenance.
Before the technician arrives, identify one or two possible installation locations.
What Makes a Good Indoor Unit Location?
Consider the following:
- An unobstructed area for proper airflow
- A stable wall capable of supporting the equipment
- Sufficient clearance around the unit
- Convenient access for future cleaning
- A suitable route for refrigerant piping and drainage
- A position that does not direct cold air continuously towards the bed or seating area
Avoid placing the aircon where cabinets, curtains or large furniture could restrict airflow.
The technician should confirm the final mounting location based on the manufacturer’s installation specifications.
3. Check the Outdoor Condenser Location
For split-type air conditioning systems, the outdoor condenser is an essential part of the installation.
The outdoor unit releases heat collected from the indoor space, so it needs adequate ventilation and a secure mounting position.
A poorly selected location may affect performance, increase vibration or make future servicing difficult.
Things to Check Before Installation
- Is there an approved location for the outdoor unit?
- Is the mounting surface strong enough?
- Will the condenser have enough ventilation?
- Can technicians safely access the unit for maintenance?
- Is there enough space around the equipment?
- Can refrigerant pipes reach the planned location within the manufacturer’s limits?
- Will the installation comply with the property’s rules?
Outdoor units should not be placed in completely enclosed spaces without adequate ventilation.
For condominiums, use only designated or approved condenser locations.
If your property does not have a suitable outdoor area, discuss alternative installation arrangements with the technician before buying the equipment.
4. Confirm Electrical Requirements Before Installation
Air conditioners require an appropriate electrical supply to operate safely.
The electrical requirements depend on the unit’s cooling capacity, electrical rating and manufacturer’s specifications.
Some properties already have a suitable dedicated circuit, while others may need electrical work before installation can proceed.
Electrical Preparation Checklist
Before the scheduled visit, confirm:
- Whether a dedicated aircon circuit is available
- Whether the electrical supply matches the equipment
- Whether the circuit breaker is appropriately rated
- Whether proper grounding is provided
- Whether electrical wiring is in good condition
- Whether additional electrical work is necessary
Never assume that an existing wall outlet is suitable for a newly purchased air conditioner.
Avoid using ordinary extension cords or overloaded adaptors to power the unit.
Electrical connections, protective devices and wiring requirements should be checked by qualified personnel according to applicable electrical standards and the manufacturer’s instructions.
Important: Homeowners should not attempt to modify electrical wiring or install circuit breakers themselves unless properly qualified.
5. Check Whether Wall Drilling Is Allowed
Split-type aircon installation commonly requires an opening through which refrigerant piping, electrical cables and drainage can pass.
Before the technician arrives, determine whether drilling is permitted in the proposed location.
This is particularly important for:
- Condominium units
- Rental apartments
- Commercial offices
- Newly renovated homes
- Properties with structural restrictions
If you are renting, obtain approval from the property owner before allowing permanent modifications.
For condominium residents, confirm whether the building requires approved drilling locations or an accredited installer.
Some buildings may have prepared aircon pipe openings, making additional drilling unnecessary.
6. Prepare a Proper Drainage Route
Air conditioners remove moisture from indoor air during cooling. This moisture becomes condensate water that must be safely drained.
For split-type systems, the installer usually connects the indoor unit to a drainage pipe or hose.
Poor drainage can result in water dripping indoors, damp walls or damage to furniture.
What Should Be Checked?
Before installation, ask:
- Where will condensate water drain?
- Is there an approved drainage connection?
- Will the drain line have the required slope?
- Does the building permit the proposed drain route?
- Is a condensate pump necessary?
The technician should determine the correct drainage arrangement.
In condominiums, drainage must comply with property management requirements. Water should not be discharged onto neighbouring balconies, walkways or other unsuitable areas.
7. Clear the Installation Area
One of the simplest ways to prepare is to provide enough working space.
Aircon technicians may need to use ladders, drills, mounting brackets and other installation tools.
A crowded room can make installation more difficult and increase the risk of accidental damage.
Before the Technician Arrives
- Move furniture away from the planned installation wall.
- Remove decorations, picture frames and fragile items.
- Clear the route between the entrance and installation area.
- Cover nearby furniture or electronics to protect them from dust.
- Keep children and pets away from the work zone.
- Provide safe access to the outdoor unit location.
- Ensure the room has sufficient lighting.
You do not need to empty the entire room. Providing a practical working area is normally enough.
If heavy furniture cannot be moved, inform the installation team before the appointment.
8. Prepare the Aircon Unit and Installation Accessories
If you purchased your air conditioner separately from the installation service, check that the equipment is ready for the technician.
Inspect the packaging for visible damage and confirm that the delivered model matches your order.
Items to Prepare
- Indoor aircon unit
- Outdoor condenser, if applicable
- Remote control
- Installation manual
- Warranty documents
- Manufacturer-supplied accessories
- Proof of purchase
- Any separately purchased installation materials
Some installation packages include standard piping, brackets and labour, while others charge separately for additional materials.
Confirm what is included in your quotation before the scheduled installation.
Do not open refrigerant connections, disassemble the equipment or perform electrical work yourself.
9. Confirm What Is Included in the Installation Quotation
Aircon installation costs can vary depending on the unit type, property layout and additional materials required.
For example, installing a split-type aircon in a bedroom with a nearby outdoor condenser location may be less complicated than installing one in a high-rise condominium.
Common Installation Cost Factors
| Installation Item | Why It Matters |
|---|---|
| Standard installation labour | Covers agreed installation work |
| Copper piping | Connects the indoor and outdoor units |
| Pipe insulation | Helps prevent unwanted heat gain and condensation |
| Drainage materials | Carries condensate water away safely |
| Condenser brackets | Supports the outdoor unit where approved |
| Additional electrical work | May be needed for a suitable power supply |
| Extra pipe length | Longer installation routes may increase material costs |
| Wall drilling | Depends on wall construction and access |
