Preparing for Air Conditioner Installation: What You Need to Know in 2026

Successful installation of residential air conditioners begins long before the installers arrive. Thorough preparation helps avoid common mistakes and ensures the system operates efficiently throughout its entire service life.

Determining the requirements for the air conditioning system

The first step in preparation is to clearly define the tasks the equipment must perform. Experts advise determining right away whether only air cooling is needed, or if the system should also provide heating and fresh air intake.

Air conditioner capacity calculation formula:
Capacity (W) = Area (m²) × 100 W/m² + Adjustments

Adjustments for accurate calculation:

• +15% for rooms with high ceilings (over 3 m)
• +300–400 W for each person who is constantly present
• +300–500 W for each high-power electrical appliance (computer, TV)
• +20% for rooms with large south-facing windows

Calculation example for a 50 m² apartment in Kyiv:
Base power: 50 m² × 100 W/m² = 5000 W
+ 2 residents: 2 × 350 W = 700 W
+ appliances (TV, computer): 800 W
+ south-facing windows: 5000 × 0.2 = 1000 W

Total power: 7500 W (7.5 kW)

Selecting the right equipment with the necessary features when installing residential air conditioners allows you to significantly save on costs and ensure a comfortable indoor climate all year round.

Budget and Timeline Planning

The installation of residential air conditioners in Kyiv follows a clear pricing structure. Standard installation takes 3–4 hours provided the wall thickness is no more than 0.8 m and the length of inter-unit connections is up to 3 m. The base installation cost is 3,500–5,000 UAH, but exceeding standard parameters results in additional costs.

Parameter	Standard conditions	Additional cost if exceeded

We recommend setting aside a 20–30% contingency in your budget for unforeseen expenses and scheduling the installation of residential air conditioners at the start of the season to get the best prices.

Preliminary approvals and permits

Given the high-rise development in Kyiv, installation must be coordinated in advance with the management company. This applies particularly to the installation of outdoor units on building facades.

1. Obtaining written permission from the management company
2. Coordinating the timing of the work with neighbors
3. Verifying the technical feasibility of installation on the selected wall
4. Ensuring unobstructed access to the installation site

Proper preparation for installation also includes creating a detailed design of the air conditioning system, taking into account all the technical nuances of the specific property.

Selecting the optimal location for the indoor and outdoor units

Proper placement of split-system units determines cooling efficiency and the duration of uninterrupted equipment operation. Installing residential air conditioners requires compliance with technical standards regarding distances, structural loads, and accessibility for maintenance.

Placement of the split-system indoor unit

Proper placement of the indoor unit ensures efficient system operation and user comfort. Installing residential air conditioners requires consideration of the specific room’s layout and its functional purpose.

Placement diagrams for different types of housing:

• Studio (25–35 m²): Install the unit on the wall opposite the window, 2.5 m above the floor. Direct the airflow parallel to the ceiling for even cooling of the entire space
• 1-bedroom apartment (35–50 m²): the optimal placement is on the wall between the living and sleeping areas, with adjustable louvers to redirect the airflow
• 2-room apartment: in the living room (15–20 m²) — in the center of the longer wall; in the bedroom (12–15 m²) — above the bed with the airflow angled 30° upward

When selecting a wall for mounting, consider its material and thickness. Aerated concrete walls less than 200 mm thick require additional reinforcement with 120–150 mm anchors. For brick walls, standard 80–100 mm anchors are sufficient. It is strictly prohibited to install the indoor unit on drywall partitions without a metal frame.

In kitchen-living rooms, the unit is placed away from the stove and refrigerator to avoid the influence of heat sources on the temperature sensors. For children’s rooms, choose the wall opposite the bed, ensuring the airflow is directed upward at a 45° angle.

Installing the outdoor unit

The outdoor unit is mounted on brackets under a window or on a balcony in compliance with fire safety regulations. The distance from the unit to the building wall must be at least 30 centimeters to ensure proper air circulation.

Brackets for the outdoor unit are made of galvanized steel with a thickness of at least 4 mm. The load on a single bracket can reach 40–60 kg, depending on the air conditioner’s capacity. Installation on balcony railings is permitted only after their load-bearing capacity has been verified by a structural engineer.

In multi-story buildings, the outdoor unit is installed in accordance with architectural requirements and with the consent of the homeowners’ association. On the first floors, the unit is placed at a height of at least 2.5 meters above the ground to prevent theft and vandalism. To protect against precipitation, a canopy with a 15–20 cm overhang is mounted above the unit.

Factors in choosing a location

The length of inter-unit connections for standard installation does not exceed 3 meters, which limits the placement options for the units. The outdoor unit is installed with consideration for condensate drainage and minimal noise levels for neighbors.

The height difference between units should not exceed 5 meters for residential models with a capacity of up to 7 kW. For greater height differences, additional oil collection loops must be installed in the compressor. The optimal orientation for the outdoor unit is the north or east side of the building, where there is less direct sunlight.

Condensate drainage is arranged via a 16-mm diameter drain pipe with a 2–3-degree slope. In winter, the pipe is insulated to prevent freezing. If natural drainage is not possible, a drain pump with a capacity of 15–20 L/h is installed.

Tools and materials required for air conditioner installation

Successful installation of residential air conditioners requires careful preparation of tools and high-quality materials. Professional installation of a split-system involves the use of specialized equipment that ensures the tightness of connections and the long-term operation of the air conditioning system.

Basic installation tools

Installing residential air conditioners requires professional tools that ensure high-quality installation and long-term system operation. A hammer drill with a 65–70 mm drill bit is essential for creating a through-hole in a wall up to 0.8 m thick. Installers use professional vacuum pumps to remove air from the refrigerant line, which is critical for the system’s future efficiency. A pressure gauge station allows monitoring system pressure during refrigerant charging and detecting potential leaks during testing.

Expensive specialized equipment can be rented: a vacuum pump (300–500 UAH/day) and a pressure gauge station (250–400 UAH/day) at the rental locations "TechnoRent" (34 Vasylkivska St.), "InstrumentService" (121 Peremohy Ave.) or "MasterTools" (176 Antonovycha St.).
