Installing an air conditioner in an apartment or house: installation rules and useful tips

Proper installation of an air conditioner directly impacts its efficiency, energy consumption, and service life. Installation errors can lead to refrigerant leaks, increased noise, heat exchanger icing, and frequent breakdowns, so it’s important to follow basic rules and technical requirements.

Before starting work, it’s important to determine the system type (split, multi-split, portable, window), the appropriate power, and the location of the units. Next, select an installation method, taking into account the wall structure, electrical access, condensate drainage, and safety requirements.

Installation Methods and Practical Tips

In practice, one of two options for wiring is chosen: concealed (in a groove) or exposed (in a box). The concealed method is more aesthetically pleasing, but requires dusty work and more complex repairs if necessary. An open unit is easier to maintain and is more often used in completed renovations.

Installation tips: determine in advance where the condensate will drain, check the load-bearing capacity of the wall, and coordinate the location of the outdoor unit with the house’s requirements. If quietness is important, choose low-noise models and consider anti-vibration mounting.

• Don’t skimp on materials: high-quality copper, insulation, and fasteners reduce the risk of leaks and vibrations.
• Consider the sun: in strong sunlight, the outdoor unit may work harder; Sometimes, proper placement or a protective canopy without blocking the airflow helps.
• Plan for maintenance: leave access for cleaning filters and servicing the outdoor unit.
• Trust the professionals: proper installation with vacuuming and inspections is the key to reliable operation, as is commonly practiced at MGM Heating and Cooling.

Bottom line: the correct installation location, a sealed duct, proper drainage, safe electrical wiring, and mandatory vacuuming are the basic conditions for an air conditioner to cool efficiently and operate reliably for many seasons.

How to choose a location for the indoor unit: height, clearances, airflow direction

The correct location of the indoor unit determines not only comfort but also cooling/heating efficiency, noise level, and energy consumption. Incorrect height, clearances, and airflow direction often result in drafts, uneven temperatures, and accelerated filter clogging.

When selecting a location, consider free air circulation, ease of maintenance, and minimal disruption to occupants. The indoor unit should operate so that the airflow is distributed throughout the room, not directed directly at the rest area or workstation.

Practical Placement Guidelines

• Installation Height: Typically, the indoor unit is placed in the upper part of the wall to allow the cool air to descend evenly and mix. Avoid installing the unit too low, as this increases the risk of discomfort from the cold airflow.
• Ceiling Clearance: Leave a gap for air intake and ease of installation; Too small a gap will impair circulation and increase noise.
• Side gaps: Avoid placing the unit against corners, curtains, or furniture—this will interfere with air distribution and make it difficult to access the lid/filters.
• Clear area in front of the unit: Avoid placing it directly opposite cabinets, shelves, or thick curtains—the air flow should be directed toward the open space of the room.
• Flow direction: Direct the blinds so that the air flow does not hit the bed, sofa, desk, or areas where people spend long periods of time. It’s best to place the unit along the room or in a free-circulation area.
• Heat and steam sources: Avoid placing the unit near stoves, radiators, humidifiers, or areas with constant steam—the sensors will not function correctly, and heat transfer will be impaired.
• Solar radiation: Avoid direct sunlight on the housing and sensors (if possible), as this reduces the accuracy of temperature control.
• Drainage and routing: Provide for reliable condensate drainage and a rational route for the line without unnecessary bends; This increases reliability and simplifies maintenance.
• Maintenance access: filters must be easily removed, and the technician must have access to connections and drainage.

1. Identify “occupied zones”: where people sleep, sit, and work – the air flow should not be directed there.
2. Choose a wall with open space: so that the air can spread throughout the room without obstructions.
3. Check for obstacles: curtains, beams, tall cabinets, decorative panels, and niches.
4. Coordinate with the route and drainage: the shorter and simpler the route, the better for efficiency and reliability.
5. Leave access: for cleaning filters and diagnostics without disassembling furniture and trim.

Summary: the best location for the indoor unit is at the top of the wall, with sufficient clearance for air intake/exhaust, without obstructions in front of the flow, and with the stream directed in free zone, not per person. Adherence to these principles ensures an even microclimate, quieter operation, and fewer maintenance issues owner.
