Cassette Air Conditioner Installation in Chișinău — 1-Day Installation with Up to 3-Year Warranty

Accurate Load Calculation Is Required

A cassette system is selected not “by area” but based on heat load: number of occupants, equipment, lighting, ceiling height, and warm air inflow. Miscalculation leads to constant compressor overload and equipment wear within 2–3 seasons.

Mandatory Refrigerant Line Vacuuming

After installing the refrigerant line, air and moisture must be removed from the system. If skipped, condensation forms inside and can damage the compressor. Proper vacuuming takes 20–40 minutes and directly affects the equipment’s lifespan.

Proper Drainage Setup

Cassette models are installed in the ceiling, so incorrect drainage slope can cause leaks and damage to the ceiling structure. In commercial properties, this may result in business downtime and additional repair costs.

Reinforced Mounting and Weight Distribution

The indoor unit weighs on average 20–35 kg. It cannot be mounted directly to drywall. Installation is performed using threaded rods anchored to the load-bearing slab; otherwise, vibrations and ceiling deformation may occur over time.

Ceiling Marking and Preparation

Before installation, the mounting point is determined considering airflow distribution and the load-bearing structure of the slab. An error at this stage leads to uneven cooling and vibrations. We check the ceiling void height (minimum 25–30 cm) and the possibility of anchoring to the concrete base.

Indoor Unit Installation

The 20–35 kg unit is mounted to the slab using threaded rods with precise leveling adjustment. Improper installation causes decorative panel misalignment and drainage issues. After fixing, we check the rigidity of the mounts and ensure there is no movement.

Outdoor Unit Installation

The outdoor module is installed on brackets or a prepared base, maintaining required clearances from walls and nearby objects. This ensures proper heat exchange and prevents compressor overheating during hot periods.

Refrigerant Line Installation

Copper pipes are insulated and connected with the correct tightening torque on the flare nuts. Poor flaring is the main cause of refrigerant leaks during the first years of operation. The line length is calculated in advance to avoid excessive compressor load.

Drainage System Setup

For cassette models, proper drainage slope is critical. If condensate drainage is incorrectly installed, water accumulates and may damage the ceiling. A drain pump is installed if necessary.

Vacuuming and Test Start-Up

After installation, the system is vacuumed to remove air and moisture. This process takes 20–40 minutes and directly affects the equipment’s lifespan. A load test start-up is then performed, checking pressure and supply air temperature.

Line Length.
Each additional meter of refrigerant piping increases material costs and installation time.

Ceiling Complexity.
Installation in drywall or designer ceilings requires structural reinforcement and precise marking.

Room Height.
For ceilings higher than 3 meters, installation complexity increases and additional equipment may be required.

Need for Special Equipment.
If the outdoor unit is installed above the second floor, lifts or rope access technicians are required.

Electrical Work.
A dedicated power line, circuit breaker, and properly sized cable are calculated individually.

The price is calculated after site inspection and reflects real technical conditions rather than “average” parameters.
