Air conditioner maintenance and repair

Maintenance is critical toindustrial facilities, where failure of the air conditioning system threatens production downtime, loss of warranty and costly repairs. ABL Engineering Group works withfactories, shopping centers, warehouses and office centers of any scale throughout Kazakhstan.

Our clients are legal entities that require a reliable partner to maintain critical infrastructure. Among them are industrial enterprises such as ArcelorMittal and other large manufacturers who understand that regular maintenance prevents production downtime and avoids expensive major repairs.

Problems that regular maintenance solves

• Risk of production downtime. A failure of the air conditioning system in a factory or warehouse is not just an inconvenience, it is a loss of income. Regular maintenance prevents critical failures.
• Risk of costly repairs. Preventive maintenance (cleaning filters, checking pressure, electrical diagnostics) is several times cheaper than replacing a compressor or heat exchanger.
• Risk of loss of warranty. Failure to maintain a service agreement will often void the manufacturer’s warranty. We provide complete documentation of all work performed.
• Risk of environmental disruption. Freon leaks are not only a loss of refrigerant, but also a violation of environmental standards. Professional diagnostics detect leaks in the early stages.
• Filters are dirty and the drainage system is clogged. These problems reduce cooling efficiency and require urgent correction.

If you manage an industrial facility of any size and want to avoid production downtime, loss of warranty and expensive repairs, contact us. We work throughout Kazakhstan: Almaty, Astana, Temirtau, Shymkent, Aktobe.

The cost of maintenance depends on several key factors: type of system (VRF/VRV, chillers, duct, cassette, precision), facility area, maintenance frequency and scope of work. ABL Engineering Group providestransparent payment without hidden fees with a detailed price list and offers flexible contract terms for servicing industrial facilities of any size. Our own production of spare parts (Temirtau, modern machine park) allows us to reduce the cost of replacing parts by 20–30%.

How is the cost of maintaining your facility calculated?

We will determine the exact price after conducting diagnostics of a specific location. The calculation is affected by:

• Object area— the larger the room, the more powerful the system and the higher the cost of maintenance.
• System type— VRF/VRV systems, chillers with fan coils, ducted units, cassette units and precision cooling systems require different amounts of work.
• Maintenance frequency— seasonal maintenance, quarterly maintenance or annual maintenance. Regular maintenance is 40–60% cheaper than emergency repairs.
• Scope of work— the standard package includes cleaning filters, checking pressure, refilling with freon, electrical diagnostics and cleaning the drainage system. Replacement of spare parts is calculated separately.

Our specialists will conduct a full inspection and offer an optimal maintenance schedule specifically for your facility. Diagnostics are carried out free of charge upon concluding a maintenance contract.

Tariffs for planned and emergency maintenance: price list

ABL Engineering Group works according to two main models:

• Regular Maintenance— maintenance contract with a fixed frequency. The cost depends on the number of visits per year and the volume of work. This approach avoids costly emergency repairs and guarantees production stability. Discounts are available for long-term cooperation.
• Emergency departure 24/7— urgent diagnostics and troubleshooting on the day of call. We will arrive within 2–4 hours within Almaty, Astana, Temirtau, Shymkent, Aktobe. The cost of an emergency call is higher than scheduled maintenance, but guarantees minimization of production downtime.

Flexible contract terms allow you to choose the optimal terms and format of cooperation. Discounts are available when concluding long-term service contracts (from 12 months). Get an up-to-date price list calculating the cost of maintenance for your facility.

We work with equipment from trusted European and Asian manufacturers. Whatever type of system is installed at your facility, we service it.

What is the maintenance frequency for an industrial system?

The frequency of maintenance depends on the type of system, intensity of use and operating conditions. Standard scheme includesseasonal maintenance (before the summer and winter seasons), quarterly maintenance and annual maintenance. Some facilities require more frequent maintenance. Our engineers will determine the optimal frequency during a consultation and inspection of your system.

What is the cost of servicing an air conditioning system?

The cost of service is calculated individually and depends on several factors:

• Type and number of systems on site
• Area and complexity of the object
• Maintenance frequency (seasonal, quarterly, annual)
• Scope of necessary work and replacement of spare parts

You can get an exact cost after consultation and diagnostics of your property. Leave a request or call us – we will calculate without hidden fees.

ABL Engineering Group operates throughout Kazakhstan. Main cities served:Almaty, Astana, Temirtau, Shymkent, Aktobe. Thanks to our own installation teams and production in Temirtau, we provide quick delivery and quality service at any facility in the republic.

Is there a minimum facility size to enter into a service contract?

Yes, we work with industrial facilities with an area of500m² or more. This is due to the specifics of our activity – we specialize in complex industrial air conditioning systems for factories, shopping centers, warehouses and office centers.

What to do if the air conditioning system stops working?

If the system does not work, this is a critical situation that requires urgent intervention.Call us immediately. Our 24/7 emergency service means we will arrive as quickly as possible, diagnose and fix the problem. Do not try to repair the system yourself – this may lead to even bigger problems.

Why doesn’t the air conditioning system cool the room?

Incorrect temperature or lack of cooling can be caused by several reasons:

• Freon leaks– loss of pressure and refrigerant
• Filter contamination– decreased efficiency
• Clogged drainage system– problems with condensation
• Pressure loss in the system
• Compressor faults or other components
• Electrical errors or system management

Only professional diagnostics will determine the exact cause. Our engineers will identify the problem and make the necessary repairs.

How often should air conditioning system filters be cleaned?

The frequency of filter cleaning depends on the intensity of use of the system and air pollution at the facility. Standard recommendation –Clean filters once a month or once a quarter with regular use. Dirty filters reduce cooling efficiency and increase the load on the compressor. Include filter cleaning in your regular maintenance plan.

What is freon refilling and when is it required?

Refilling with freon (refrigerant) is a replenishment of the amount of refrigerant in the system. Required whenpressure loss and freon leaks. Leaks can be caused by worn seals, damaged piping, or improper operation. If the system has lost pressure, it is necessary to identify and eliminate the cause of the leak, and then refill it. Refueling without fixing the leak is a temporary solution.

Is it possible to service different types of systems by one contractor?

Yes, it’s possible. ABL Engineering Group providescomprehensive service for all types of industrial systems— VRF, chillers, duct, cassette, multisplit, precision. One contractor can service the full range of equipment at your site, simplifying contract management and ensuring a consistent level of quality.

What problems with the system require urgent attention?

The following problems requireurgent emergency departure:

• The system is completely down– failure
• Freon leaks— visible damage to pipelines
• Incorrect temperature– the system does not cool at all
• Noise and vibration– signs of compressor malfunction
• Smell or water— condensation, clogged drainage system
• Errors on the display– control failure

If any of these problems occur, call us immediately. Emergency departure 24/7 will prevent production downtime.
