In home renovations, the timing of central air conditioning installation is a factor that needs"The critical phase of 'pre-decision-making.' As large equipment that must be installed simultaneously with water and electricity projects, it cannot be purchased and installed like regular household appliances at a later stage of decoration. Below is one of the large equipment required to enter the entire decoration process."
One: Optimal Time for Central Air Conditioning Installation
Key Timing: Electrical and Water Reform Phase (Weeks 1-2 of Renovation)
Simultaneous Construction with Electrical and Water Systems: Central air conditioning must be installed concurrently with the entry of electricians and plumbers, requiring both to perform overlapping work and coordinate with each other.
- Specific Milestone: Once the wall alterations are completed, confirm the air conditioning plan and then schedule the manufacturer to come for installation.
- Key Reasons: Central air conditioning requires advance planning of electrical layouts and reserving power and control lines. Installing it after the completion of water and electricity work will significantly increase the difficulty and cost of re-wiring.
2. Installation Process: Three Phases
On the first installation, upon the arrival of water and electricity, the indoor unit is hoisted, refrigerant pipes and drain pipes are laid, signal lines are installed, and protective wrapping is applied.
Second installation, following the first installation24 hours: Install outdoor units, nitrogen fill and pressure maintenance, test system airtightness
The third installation is complete, with the ceiling finished, the outlets and returns are installed, and the equipment is undergoing tuning and inspection.
II. Coordination with Other Renovation Processes
Must be completed before the following processes:
Before ceiling installation: indoor units and pipes must be installed and concealed within the ceiling.
Before the bricklayers and carpenters arrive: prevent damage to air conditioning lines during subsequent construction.
In sync with the following processes:
Hydroelectric and Waterworks Reconstruction: Construction at the same time, unified planning of pipeline routes.
- Fresh Air Systems: It is recommended to install fresh air systems simultaneously with central air conditioning.
Three: Preparations to Be Made Before Renovation
Design Scheme: Determine the air conditioning plan according to the apartment layout, area, and usage requirements before renovation.
2. Equipment Selection: Pre-select brands and models, allocate a procurement cycle of 1-2 weeks
3. On-site Briefing: Before installation, organize the air conditioner manufacturer, designer, and electrician for an on-site briefing to clarify pipe location and wiring requirements.
IV. Important Notes
Height Requirement: The benefit of heightOver 2.6 meters, central air conditioning will take up 20-30 cm of ceiling height.
Seasonal Selection: Spring and autumn are peak installation seasons, with favorable weather and relatively discounted prices; extreme heat in summer and severe cold in winter can affect installation quality.
Power Reserve: The central air conditioning power lines will be installed by the renovation company, and planning should be done in advance.
Professional Installation: Always choose a qualified installation team; installation quality directly affects the usage effect.
In summary: Central air conditioning is a pre-installed appliance; the earlier the planning, the better. Once decided to install, choose the brand and design plan before the renovation begins, and have the air conditioning installers arrive on the first day the electricians and plumbers start.
