Room Size vs BTU Requirement 

• 9,000 BTU: These models work well in spaces up to 15 square meters including bedrooms.

• 24,000 BTU: Air conditioners with 24,000 BTUs work best for large living rooms that measure between 37 and 46 square meters.

Measure the area of the space and choose the aircon size accordingly. Take help from the professional during this process if required.

Step 6: Preparing Your Home for Aircon Installation 

After you choose your air conditioning unit and arrange the replacement, it’s time to get ready for the installation.

Clear the Installation Area 

The area chosen for aircon installation should be completely free from furniture and any other obstructions.

Choose the area for indoor and outdoor unit

Split system air conditioners require a designated space for the condenser and indoor unit. Split or multi-split air conditioning systems require preparation of walls and ceilings for installation.

Protect Your Furniture 

The installation of air conditioners generates substantial dust which becomes especially troublesome when drill work for mounting holes is necessary. Guard your furniture and other items by draping them with fabric or plastic sheeting.

Check Electrical Systems 

Your home’s electrical system should be able to handle the electrical demands of the new aircon unit especially when installing large or multiple units. During the pre-installation visit, the aircon installer will typically conduct an electrical system check in your home.

 

Step 7: Post-Installation Maintenance

After the installation is done, follow below guidelines for consistent performance:

• Regular Servicing: To keep your aircon working effectively, schedule maintenance services for every 3-6 months.
• Clean Air Filters: Dirty air filters can reduce efficiency. Clean the filter each month and replace when necessary.
• Check Refrigerant Levels: Low refrigerant levels can affect cooling performance. During routine maintenance visits, ensure your service technician checks the refrigerant levels.
• Monitor for Leaks: Check for refrigerant leaks because they can decrease system efficiency and create environmental risks.
