General air conditioner installation

GENERAL AIR CONDITIONER INSTALLATION:

PREPARATION

• Our team and the ordered air conditioner, if it was ordered from us, arrive at the site at the agreed time.
• If you accept our quotation, we arrange an installation appointment.

INSTALLATION

• We inspect the site, after which our colleagues send a written quotation.
• We measure the indoor unit at the designated location, secure it properly and make the 55 mm opening required for the air-conditioning pipework.
• We confirm the outdoor unit location, install the bracket and secure the outdoor unit.
• If required, we install cable channels or wall chases and connect the air-conditioning pipework and control cables.
• Pressure test with high-purity nitrogen.
• Evacuation and vacuum hold test.
• Commissioning.

HANDOVER

• The installers inform the customer that the work is complete.
• They demonstrate the indoor and outdoor units in operation and explain the basic operating rules.
• After successful handover, they provide the equipment documentation.

Air conditioner maintenance

AIR CONDITIONER MAINTENANCE:

Based on many years of experience, regular maintenance of air-conditioning and ventilation systems by our specialists extends equipment service life by 30-40% and reduces repair costs by 60-70%.

Operational reliability increases significantly and unexpected faults can usually be prevented. Our maintenance specialists optimise operation by recording adjustment values and evaluating operating experience. They inform the operator about irregularities, expected failures and necessary modifications and record them in writing on the work sheet.

We provide regular maintenance according to the agreed schedule and notify the customer of the appointment in advance. For repairs arising during air-conditioner maintenance, only the installed material is charged. Contracted partners receive priority for scheduled maintenance and urgent repairs. We keep parts and other equipment primarily in stock for contracted partners. If a fault occurs within one week after maintenance, we do not charge labour, providing a quality guarantee for our maintenance work.

With a maintenance contract, our company undertakes to keep the maintained equipment running continuously. If a fault cannot be repaired immediately or within 24 hours after the call-out, we inform the operator of the expected repair time. If this is expected to exceed 72 hours, we arrange the immediate installation of a backup unit.

Depending on the customer’s needs, we can provide call-out times within 6 or 12 hours and maintain 24-hour weekend duty. As our company is based in Szigetszentmiklós, no separate mileage fee is charged in the surrounding area.

We recommend the operating-hour inspections specified in the manufacturer’s manuals. Many years of practical experience show that demanding technical installations may require a permanent standby service. If requested, we can provide a permanently available service team and keep the required maintenance materials in stock according to the manufacturer’s manual.

Air conditioner energy consumption

AIR CONDITIONER ENERGY CONSUMPTION:

Offices contain many unnoticed heat sources. Every switched-on computer, printer and copier releases heat that the air conditioner must handle. Switch equipment on only when it is needed and you can save twice over.

A conventional split unit may be classed D or E, while an inverter air conditioner is commonly class A or B and is much more energy efficient. An inverter unit adapts its output to the preset room temperature and gradually increases or reduces power according to the actual cooling or heating demand. A conventional unit is more like a light switch: it turns on and runs at full power.

If a conventional split unit needs 50% of its maximum cooling capacity, it runs at 100% for 30 minutes and the compressor stops for 30 minutes within one hour. An inverter unit runs for 60 minutes at 50% output, when its efficiency is better. Once the desired temperature is reached, it reduces compressor speed. This can save about 44% energy compared with a conventional solution.

Air conditioner efficiency is shown by the COP value. This quotient indicates how many units of cooling output are obtained from one unit of electricity. The higher the value, the more efficient the unit. An average unit operates at a COP of 2-3 under well-sized conditions, while a higher-quality unit can reach 4.4.

A poorly designed or incorrectly sized system can cause a high electricity bill. Consumption depends on room volume, walls and window size, so choose a unit with suitable capacity and consider the orientation of glazed surfaces.

Consumption increases when doors are opened frequently, windows are left open, large glazed areas receive strong sunlight, insulation is inadequate or the difference between outdoor and indoor temperature is too large. For a room with large west- or south-facing windows, shading the glass is often more economical than simply increasing air conditioner capacity.

The heat produced by people in the room, usually around 100 watts per person, should also be considered. Environmental organisations recommend energy-efficient models that do not use climate-damaging refrigerants. Switch the air conditioner on mainly during the warm part of the day and leave windows open at night when possible. Before reaching for the remote, cross-ventilation can significantly improve how the temperature feels.
