Ducted Air Conditioner Installation in Chișinău — Turnkey Design & Installation in 2–5 Days

Installation must be completed before finishing works — otherwise the cost increases by 1.5–2 times

A ducted system requires installation of air ducts, drainage, and refrigerant lines within the ceiling space. A technical clearance of 25–40 cm is required. If the design is done after renovation is completed, drywall must be opened, lighting fixtures removed, and the ceiling partially rebuilt. This increases both budget and timeline. Therefore, engineering calculations and duct layout must be approved before finishing works begin.

Accurate heat load calculation is mandatory — not selection “by square meters”

Installation starts not with equipment mounting but with calculating heat gains. We consider floor area, ceiling height, orientation to cardinal directions, number of windows, electrical appliances, and average occupancy. A sizing error of even 20% results either in continuous compressor operation without pauses or frequent start-stop cycles. Both scenarios increase energy consumption and reduce system lifespan.

Air ducts require proper balancing and sound insulation

Incorrect duct diameter or lack of balancing creates noise and uneven air distribution. Air velocity must be calculated so that noise levels in residential spaces do not exceed 20–25 dB. Sound insulation materials and balancing dampers are used for this purpose. Without these components, the system may function, but comfort will not be achieved.

Drainage and line slope are critical for long-term operation

Condensate is discharged through a drainage system with a mandatory slope of 1–2 cm per meter. Errors at this stage lead to moisture accumulation and ceiling leaks. In multi-story buildings, drain pumps are additionally installed when gravity drainage is not possible. This component is often ignored by unqualified installers, leading to costly repairs after 1–2 seasons of operation.

Power supply and automation must be calculated separately

A ducted system is connected to a dedicated power line with automatic protection. Compressor starting currents are higher than in standard split systems. Improper connection may cause wiring overheating or breaker trips under peak loads. In 150–250 m² home projects, this requirement is included in the electrical panel design at the planning stage.

Full Engineering Design Before Installation — No “We’ll Figure It Out On Site”

We do not start installation without calculating heat gains and preparing a duct layout plan.
Capacity in kW is determined considering ceiling height, windows, sun exposure, and equipment.

A miscalculation of even 15–20% leads to up to 25% higher electricity consumption and accelerated compressor wear.
That’s why: first the design — then the installation.

Indoor Unit Installation with Vibration Isolation and Precise Positioning

The unit is installed within the ceiling void (25–40 cm) with mandatory vibration isolation.
Improper mounting transfers noise to the structure and creates humming in bedrooms.

We calculate:

– allowable refrigerant line length
– height difference
– service access

These factors affect equipment lifespan — 10–15 years.

Refrigerant Line and Drainage Installation Without Leak Risk

Copper pipes are fully insulated.
Drainage is installed with a 1–2 cm per meter slope or a drain pump is added.

90% of leaks after 1–2 seasons are caused by improper drainage.
We check tightness and pressure before system start-up.

Duct Calculation and Balancing — Even Temperature in All Rooms

Duct diameter and length are calculated, not selected “approximately.”
Balancing dampers are installed to regulate airflow.

Without this, one room may be 22°C while another remains at 27°C.
Our goal — no more than 1–2°C difference.

Dedicated Power Line and Automation Protection

A ducted air conditioner consumes more power than a wall-mounted split system.
We connect the system to a dedicated breaker sized for starting currents.

This prevents breaker trips during +35°C summer heat.

Vacuuming and Commissioning — Mandatory Step

Before start-up, the system is vacuumed to remove air and moisture.
Without this, compressor lifespan can decrease significantly.

After start-up we check:

– pressure
– inlet and outlet air temperature
– noise level
– proper automation operation

Only after these checks is the project handed over.
