Chillers Service with Agent Site
The chiller is the heart of central air conditioning in large buildings — factories, malls, hotels, hospitals, data centers and universities. When it stops, cooling stops across the whole facility, so getting the diagnosis right on the first visit matters. We repair and maintain water-cooled chillers (rejecting heat through a cooling tower), air-cooled chillers (rejecting heat directly to the air), screw chillers (helical compressors) and absorption chillers (driven by steam, hot water or waste heat). Call 16062 — we cover Cairo, Giza, Qalyubia, Alexandria, Matrouh (North Coast), Sharqia, Gharbia and Dakahlia.
Our technicians and cooling engineers have hands-on experience with chillers from York (Johnson Controls), Carrier (AquaForce, AquaEdge, 30HXC), Trane (CenTraVac, Sintesis, RTAC), Daikin (Magnitude, Pathfinder), McQuay, Mitsubishi Heavy Industries, Hitachi, LG, Smardt, Climaveneta, Clivet and Multistack. The work covers centrifugal, screw and magnetic-bearing chiller maintenance, compressor repair and replacement, evaporator and condenser leak repair, refrigerant charging (R-134a, R-1234ze, R-513A, R-410A or R-32, depending on the chiller), cooling-tower, pump and pipework servicing, controller and BMS-connection checks, vibration analysis and thermal imaging, and water treatment for water-cooled chillers. Facilities that need regular care can arrange scheduled visits — one call to 16062 and we arrange the technician's visit.

Water-Cooled Chiller Repair
Water-cooled chiller repair — the most efficient and most common type in large facilities. The chiller rejects heat through a separate cooling tower that cools the condenser water, so it uses less electricity than an air-cooled unit of the same capacity. Suited to large malls, hospitals, factories, universities, airports and large hotels. Brands: York YK, Carrier 19XR/19XRV, Trane CVHE/CVHF, Daikin Magnitude and Smardt.
A water-cooled chiller is built around the compressor (usually centrifugal at large capacities, or screw at medium ones), the evaporator, where the refrigerant evaporates and draws heat from the chilled-water loop, the condenser, where it condenses and rejects heat to the cooling-water loop, and the expansion valve (mechanical or electronic). Around them sit the chilled-water pump (circulating cold water to the AHUs and fan coils), the cooling-water pump (sending warm water to the cooling tower), the cooling tower, and make-up water treatment and chemical dosing. The refrigerant is usually R-134a, or lower-impact alternatives such as R-1234ze and R-513A. The most common faults: scale in the condenser tubes from poor water treatment, refrigerant leaking from the mechanical seal on open-drive compressors, worn compressor bearings, deteriorated cooling-tower fill, cavitation in the cooling-water pump, failed sensors, and a controller that needs updating.
Signs it needs service
- The controller suddenly shows a code or alarm
- Power consumption has risen noticeably at the same load
- The evaporator or condenser approach temperature has risen
- Unusual vibration or noise from the compressor
- Refrigerant leaking at the mechanical seal
- Chilled-water supply temperature above the setpoint
- The cooling-water pump is loud and vibrating (cavitation)
- Deteriorated cooling-tower fill
- Low oil pressure in the compressor
- Repeated BMS alarms from the same sensor
- The chiller keeps starting and stopping (short cycling)
- The refrigerant charge keeps dropping with no visible leak
Common faults
- Condenser tube scaling from poor water treatment — one of the most common faults
- Refrigerant leaking from the mechanical seal on open-drive compressors
- Worn compressor bearings (centrifugal or screw) — requires an overhaul
- Pitting corrosion in the condenser tubes from incorrect water chemistry, detected by eddy-current testing
- A burnt-out compressor motor (rare, but costly)
- A failed expansion valve (mechanical or electronic)
- Scale and algae on the cooling-tower fill
- Sludge and silt inside the condenser tubes
- A failed controller or display (such as OptiView on York or Tracer on Trane)
- Failed pressure and temperature sensors
- A failed mechanical seal on the cooling-water pump
- Failed hot-gas bypass solenoid valves
What we do
- Condenser tube cleaning with brushes + chemical descaling
- Refrigerant leak repair and recharge (R-134a, R-1234ze or R-513A, depending on the chiller)
- Compressor overhaul (bearings, seals and internal parts)
- Eddy-current tube testing and plugging or replacing damaged tubes
- Mechanical seal replacement and shaft repair
- Expansion valve replacement and calibration

- New water-cooled chiller installation and commissioning, after a site survey
Care tips
- A continuous water-treatment program is essential — scale cuts condenser efficiency quickly
- Check the evaporator and condenser approach temperatures daily — a rise is a warning
- Log pressures, temperatures, currents, water flow and load every day
- Regular oil analysis catches bearing wear early
- Periodic eddy-current testing of the tubes on critical or older chillers
- Inspect the cooling-tower drift eliminators regularly — important for Legionella prevention
- Do not run the chiller without proper water treatment — the wrong water chemistry corrodes the tubes
- Check the refrigerant charge from time to time using pressures and saturation temperatures
Questions
Power consumption suddenly jumped. Why?
Usually scale has built up in the condenser tubes, so heat transfer drops and the compressor works harder for the same load. The fix: mechanical cleaning and chemical descaling, and a review of the water-treatment program.
Do you work on the York YK centrifugal?
Yes — the technician reads the codes and alarms on the OptiView panel and diagnoses with on-site measurements. Parts (compressor parts, VSD, sensors, controllers) are original or compatible depending on the part and model, including for older units.
Our Trane CenTraVac shows a Low Evaporator Refrigerant Temperature diagnostic. What does it mean?
It means the refrigerant temperature in the evaporator has dropped below the allowed limit. Common causes: a low refrigerant charge, an expansion valve not opening enough, weak chilled-water flow, or a sensor reading wrongly. The technician finds the cause by measurement.
R-134a is leaking from the seal. Can it be fixed without taking the chiller offline?
If the leak is minor: a temporary top-up and a seal replacement scheduled in the next maintenance window. If it is major: replace the seal straight away, then a pressure test, evacuation and recharge. R-134a is expensive and harms the environment, so putting the repair off does not pay.
What is eddy-current testing, and what does it cost?
A non-destructive test that detects pitting and cracks inside the tubes before they leak — useful for older chillers and for chillers in salty or industrial environments. The cost depends on the number of tubes and is set after a site survey.
Do you service oil-free magnetic bearing chillers?
Yes — such as Smardt and Daikin Magnitude. Magnetic bearings need no oil and no oil analysis and run more quietly, but the bearing controller is complex, so servicing them takes a specialist technician.
Air-Cooled Chiller Repair
Air-cooled chiller repair — suited to hotels, commercial buildings, medium-sized factories and sites where water is limited, such as the North Coast. There is no cooling tower or water treatment and installation is simpler, but efficiency is lower than a water-cooled unit and drops further in extreme heat. Brands: Carrier AquaForce 30XA, Trane RTAC and Sintesis (RTAF), York YLAA, Daikin EWAQ and McQuay AWS.
An air-cooled chiller rejects heat straight to the air through large finned condenser coils and axial fans (more fans as capacity rises). Its parts: compressors (scroll at small capacities, screw at medium ones), the condenser coils (copper tubes and aluminium fins), condenser fans, usually with variable-speed drives, the evaporator (plate or shell-and-tube), electronic expansion valves, a refrigerant receiver, liquid-line solenoid valves and the controller. The refrigerant is usually R-410A, or R-32 on newer models, and R-134a on some large units. The most common faults: condenser coils clogged with dust and sand (critical at desert and coastal sites), fan motors burning out in the heat, refrigerant leaks from brazed joints cracked by vibration, compressor damage from liquid slugging, drives damaged by voltage swings, and a controller affected by heat.
Signs it needs service
- Power consumption has risen noticeably, especially in summer
- Very high discharge pressure, close to the trip limit
- Some condenser fans have stopped
- The condenser approach temperature has risen sharply
- A visible refrigerant leak or oil stains at the joints
- The chiller trips by itself around midday (high-pressure trip)
- Condenser coils caked with dust and sand
- A loud, vibrating compressor
- A drive (VFD) error code
- Repeated BMS alarms from temperature sensors
- Chilled-water temperature does not reach setpoint at peak times
- The defrost cycle does not complete (on heat-pump models)
Common faults
- Condenser coils clogged with dust — one of the most common faults at desert and coastal sites
- Condenser fan motors burning out in summer
- Refrigerant leaking from brazed joints (vibration cracks the brazing)
- Variable-speed drives damaged by voltage swings
- A failed compressor (scroll or screw) from liquid slugging
- Failed electronic expansion valves
- Failed pressure and temperature sensors
- A clogged liquid-line filter drier
- A controller damaged by heat stress
- Coil fins corroded by salt spray (coastal sites)
- Fan bearings worn by continuous running
- A cracked refrigerant receiver from pressure cycling
What we do
- Condenser coil cleaning with pressure washing and suitable chemicals
- Condenser fan motor and drive replacement
- Refrigerant leak repair and re-brazing
- Refrigerant recharge (R-410A, R-32 or R-134a, depending on the chiller)
- Compressor replacement (scroll or screw)
- Electronic expansion valve replacement and calibration
- Pressure and temperature sensor replacement
- Liquid-line filter drier replacement
- Controller repair or reprogramming
- Anti-corrosion coil coating (for coastal sites)
- Fan bearing replacement and balancing
- New air-cooled chiller installation and commissioning, after a site survey
Care tips
- Clean the condenser coils every few months — more often at dusty and desert sites
- Check the condenser fans regularly — report any stopped fan at once
- Use an anti-corrosion coating on the coils at coastal sites
- Log the discharge pressure daily — a rise usually means dirty coils
- Check the refrigerant charge from time to time — leaks are common on air-cooled units
- Fit surge protection on the drives
- Check the fan bearings from time to time — an unusual noise means they need replacing
Questions
Power consumption suddenly jumped in summer. Why?
Usually the condenser coils are dirty with dust and sand, so heat rejection weakens and the compressor works harder. The fix is a professional coil clean — and at dusty sites the coils need cleaning more often.
Do you work on the Carrier 30XA AquaForce?
Yes — the Carrier AquaForce 30XA and AquaSnap 30RB. The technician reads the codes on the controller and diagnoses with on-site measurements; parts are original or compatible depending on the part and model.
The compressor on our Trane RTAC or Sintesis has failed. Repair or replace?
It depends on the damage: mechanical damage (bearings or internal parts) can often be overhauled, while an electrical failure (a burnt winding) usually means replacement. The RTAC is the older series and the Sintesis (RTAF) the newer one, and the procedure depends on the model — the technician confirms the time and price after the inspection.
Our York YLAA at a coastal site has very high discharge pressure. Why?
The most common cause at coastal sites is condenser coils fouled with sand and salt spray. Next come a failed fan motor (weak airflow) and a refrigerant overcharge. An inspection finds the cause; prevention means regular coil cleaning and an anti-corrosion coating.
Do you install air-cooled chillers at new sites?
New installations are assessed after a site survey (load calculation, rooftop lifting, pipework and power) — call 16062 and we will confirm whether the project is within the scope of our services.
Can a North Coast hotel arrange regular maintenance?
We can agree scheduled visits: cleaning salt and sand off the coils, checking the coating, checking the fans and bearings, refrigerant-leak detection and pressure logging. Call 16062 for details.
Our coils are corroded by salt spray. What is the fix?
If the corrosion is minor: a protective coating and sealant. If it is advanced and the fins are crumbling, the coil has to be replaced — a major job that may need a crane. Prevention: regular coating and cleaning at coastal sites.
Screw Chiller Repair
Screw chiller repair — suited to factories, process cooling, food, pharmaceutical and plastics plants, data centers and mid-sized malls. Screw chillers perform well at part load because the slide valve adjusts capacity gradually, without the compressor cycling on and off. Brands: Carrier 30HXC, Trane RTAC, York YS, Daikin EWWD, McQuay AGS and Bitzer compressors.
A screw chiller uses a screw compressor with two meshing rotors (male and female) that compress the refrigerant smoothly with little vibration. A slide valve inside the compressor meters the refrigerant, so capacity changes gradually with the load. The parts: the compressor (usually semi-hermetic and oil-lubricated), the oil separator, the oil cooler, an oil pump on some models, the evaporator (usually shell-and-tube), the condenser (water- or air-cooled), electronic expansion valves, suction and discharge pressure sensors, and a PLC controller. The refrigerant is usually R-134a, or R-513A or R-1234ze on newer models. The most common faults: oil carried away with the refrigerant and not returning (oil migration), worn rotor bearings, a clogged oil filter, a sticking slide valve, the oil pump, a dirty oil-separator element, and a compressor motor burning out after bearing failure.
Signs it needs service
- Low oil level in the compressor sight glass
- Low oil pressure even though the pump is running
- A new vibration or noise from the compressor
- The slide valve does not respond to the controller
- The compressor will not reach full capacity
- Very high discharge temperature
- The oil cooler approach temperature has risen
- A high pressure drop across the oil separator (clogged element)
- A visible refrigerant leak around the compressor shaft seal
- The compressor takes longer than usual to start
- Controller codes for low oil pressure, high discharge temperature or motor overload
- Rising refrigerant use (frequent top-ups)
Common faults
- Oil carried out of the compressor with the refrigerant and not returning (oil migration) — one of the most common faults
- Worn rotor bearings (requires a compressor overhaul)
- An oil filter clogged with carbon
- A sticking slide valve (hydraulic or mechanical)
- A failed oil pump
- A clogged oil-separator element
- A burnt-out compressor motor (rare, but costly)
- A failed electronic expansion valve stepper motor
- Scale in the oil cooler (on water-cooled oil coolers)
- Failed pressure sensors (suction, discharge, oil)
- Failed hot-gas bypass solenoid valves
- A PLC controller damaged by voltage swings
What we do
- Compressor oil and oil filter change on the manufacturer's schedule
- Oil-migration diagnosis + oil recharge + oil-return circuit repair
- Compressor overhaul (bearings, seals and rotors)
- Slide valve repair and hydraulic cylinder replacement
- Oil pump and motor replacement
- Oil-separator element replacement
- Compressor motor replacement (after a complete failure)
- Electronic expansion valve replacement
- Descaling a water-cooled oil cooler
- Refrigerant recharge + leak detection
- PLC controller programming or updating
- Vibration analysis, oil analysis and a maintenance report
- New screw chiller installation and commissioning, after a site survey
Care tips
- Regular oil analysis catches wear metals and acidity early
- Change the oil and filter on the manufacturer's schedule
- Check the oil sight glass daily (level and colour — dark oil means contamination)
- Log oil pressure and suction and discharge pressures daily
- Check the slide valve position on the controller regularly — it must respond smoothly
- Check compressor vibration from time to time
- Do not run a screw chiller below its minimum load — it causes short cycling and oil-return problems
- Use exactly the oil the manufacturer specifies for the chiller's refrigerant
Questions
The oil level in our screw compressor keeps dropping. Why?
Usually oil is being carried away with the refrigerant and not returning to the oil sump (the oil separator). Causes: a dirty oil-separator element, a blocked oil-return line, or low refrigerant velocity in the evaporator. The fix: clean the oil separator and check the oil-return solenoid valves.
Do you work on Bitzer screw compressors?
Yes — Bitzer compressors (HS and CSH series), with original or compatible parts and overhaul kits depending on the part and model, including older compressors.
The slide valve on our Carrier 30HXC is not responding. What is the fix?
The slide valve is moved hydraulically by oil pressure. If it does not respond, the oil pressure is weak, a solenoid valve has burnt out, or the valve itself is mechanically stuck. The technician reads the faults on the controller and measures the oil pressure to find the cause.
The compressor motor has burnt out. How long will the repair take and what will it cost?
Replacing a compressor motor on a screw chiller is a major job: recovering the refrigerant, replacing the motor (sometimes with a crane to lift the compressor), evacuation, recharging refrigerant and oil, and start-up. It can take days, and the cost depends on the capacity and model — you get a written quote after the inspection and before work starts.
A service reminder appeared on our Trane RTAC. What should we do?
Service reminders appear by operating hours (oil change, filter change, vibration check). Read the reminder on the controller and mention it when you call 16062, and the technician will set the required service according to the manufacturer's schedule.
Are parts available for a Daikin water-cooled screw chiller?
Yes — we work on Daikin water-cooled screw chillers such as the EWWD, and on its water-cooled scroll chillers such as the EWWQ-G, with original or compatible parts depending on the part and model.
Can a food factory with screw chillers arrange regular maintenance?
We can agree scheduled visits: oil analysis, vibration checks, refrigerant-leak detection, a slide-valve check and a review of the compressor logs. Call 16062 for details.
Absorption Chiller Repair
Absorption chiller repair — a specialist type driven by a heat source instead of a compressor: steam, hot water, direct gas firing, or waste heat from cogeneration. There is no mechanical compressor; it uses a lithium bromide (LiBr) and water solution. It uses very little electricity compared with a mechanical chiller, but it is larger, slower to respond and more expensive to buy. Suited to sites with surplus steam or waste heat, or that need to cut peak electrical demand. Brands: Yazaki, LG, Carrier 16JT, Trane Horizon, Panasonic (Sanyo), EAW and Broad.
An absorption chiller is chemically more complex than a mechanical one. Its main parts: the generator, where the heat source boils water vapour out of the LiBr solution; the condenser, where that vapour condenses; the evaporator, where the water evaporates under vacuum and draws heat from the chilled-water loop; the absorber, where the concentrated solution absorbs the vapour; the solution pump; and a solution heat exchanger that improves efficiency. Types: single-effect, driven by low-pressure steam or hot water with a COP of about 0.7; double-effect, driven by higher-pressure steam with a COP of about 1.2; direct-fired; and hot-water units for waste-heat sources. The most common faults: crystallization of the solution — the most serious, as it solidifies and blocks the circuit; air ingress and loss of vacuum; the solution pump; leaking heat-exchanger tubes; depleted corrosion inhibitor; and the wrong solution concentration.
Signs it needs service
- Chilled-water supply temperature above the setpoint
- Heat-source use (steam, gas or hot water) has suddenly risen
- The unit is losing vacuum (internal pressure rising — a leak)
- Unstable solution concentration
- Unusual noise from the solution pump
- A crystallization warning on the controller
- COP far below design
- Leaks from the heat-exchanger tubes
- Visible rust on the shell
- Unusually dark solution (contamination)
- Low inhibitor level in a solution sample
- Capacity control does not respond
Common faults
- Solution crystallization — the most serious fault; the unit stops until it is cleared
- Loss of vacuum — air ingress spoils the solution chemistry
- A failed (hermetic) solution pump
- Leaking heat-exchanger tubes
- Depleted corrosion inhibitor in the solution (topped up according to solution analysis)
- Damaged generator tubes (steam-side corrosion on steam-driven units)
- A failed vacuum (purge) pump
- A failed solution heat exchanger
- A failed refrigerant (water) pump (on some large models)
- Clogged strainers in the solution circuit
- A failed capacity-control valve (steam or hot-water flow control)
- Failed temperature or pressure sensors
What we do
- Decrystallization (dissolving crystallized LiBr)
- Vacuum leak repair and vacuum pump service
- Solution pump replacement (hermetic)
- Heat-exchanger tube repair (plugging or replacement)
- Solution analysis and inhibitor top-up
- Solution concentration adjustment
- Refrigerant (water) replacement and LiBr recharge
- Capacity-control valve replacement
- Temperature and pressure sensor replacement
- Generator tube inspection and repair
- Controller programming or updating
- Solution quality testing and chemistry restoration
Care tips
- Have the solution analysed (LiBr concentration, inhibitor and contaminants) at the intervals the manufacturer recommends
- Watch the vacuum pressure daily — air ingress endangers the whole unit
- Watch the heat source (steam pressure or gas) daily
- Do not run the chiller in cold conditions without pre-heating (crystallization risk)
- Check the solution colour weekly (dark means contamination)
- Log heat-source use and cooling load to track the daily COP
- Inspect the heat-exchanger tubes every year (with eddy-current testing where available)
Questions
What is the main advantage of an absorption chiller?
Very low electricity use, because there is no compressor — ideal for sites with a cheap heat source (steam from a boiler, gas or waste heat). But it costs more to buy and takes more space.
Do you work on Yazaki absorption chillers?
Yes — such as the Yazaki WFC-SC and CH series, with original or compatible parts depending on the part and model, and lithium bromide solution to the manufacturer's specification.
Our chiller has crystallized. Can it be repaired?
Yes — by dissolving the crystals with controlled heating and recovering the solution. It is a specialist procedure that can take many hours, and done wrongly it can damage the unit. Prevention matters more: a stable heat source, pre-heating in cold weather and monitoring the solution concentration.
A heat-exchanger tube is leaking. Repair or replace?
If only a few tubes are damaged, they are plugged with suitable tube plugs and the chiller keeps running. If many are damaged, part of the tube bundle is replaced. The time is set after the inspection and may need a crane and special tools.
We have an LG absorption chiller at a hotel. Can you repair it?
Yes — we work on LG absorption chillers, with original or compatible parts depending on the part and model.
Do you install new absorption chillers for factories?
New installations are assessed after a site survey and a study of the heat source (steam pressure and flow) — call 16062 and we will confirm whether the project is within the scope of our services.
Can absorption and mechanical chillers work together at the same site?
Yes — hybrid systems are common in large factories: the absorption chiller carries the base load on cheap steam, and the mechanical chiller covers the peaks. It saves electricity and improves reliability. Call 16062 for details.

- Safety: do not open the electrical panel or loosen any refrigerant or oil connection yourself — a chiller runs at high voltage and high pressure; that is a technician's job
- Check refrigerant pressures regularly and log the values — drift is an early warning
- Have the oil analysed at the intervals the manufacturer recommends — it catches compressor wear early
- Check vibration from time to time — abnormal vibration means the bearings need checking
- Keep a continuous water-treatment program on water-cooled chillers — scale cuts efficiency
- Inspect for refrigerant leaks regularly — R-134a and R-1234ze are expensive and harm the environment
- Log the evaporator and condenser approach temperatures — a rise means fouled tubes
- Keep a daily operating log — pressures, temperatures, currents and load
- Shut the chiller down properly (pump-down) during closed seasons, following the manufacturer's instructions
- If you have a BMS, set up alerts on critical values
Frequently Asked Questions
How do I book a chiller technician?
Call 16062 — the hotline answers 24 hours a day. Give us the chiller type, brand, model and serial number, the capacity in tons, the facility type, and the fault or code shown, and we book a visit at the earliest available slot for your area (visits run 9 AM–9 PM).
What is the difference between centrifugal, screw and scroll chillers?
Centrifugal: for very large capacities and highly efficient at full load — suited to large malls and hospitals. Screw: for medium capacities, with good part-load performance — suited to factories and hotels. Scroll: for small capacities and the cheapest — suited to offices and large shops.
What is the difference between water-cooled and air-cooled chillers?
Water-cooled: more energy-efficient, but it needs a cooling tower and water treatment and costs more up front — suited to large continuous loads (factories, malls, hospitals). Air-cooled: simpler to install, with no cooling tower and no water use, but its efficiency drops in very hot weather — suited to medium loads and sites where water is limited.
Do you work on York YK, Carrier 19XR and Trane CVHE chillers?
Yes — we work on all three. The technician reads the codes and alarms on the control panel (such as OptiView on York chillers) and diagnoses with on-site measurements; parts are original or compatible depending on the part and model, including for older units.
Do you offer scheduled maintenance for hospitals and other critical sites?
We can agree a schedule of regular visits based on the number of chillers and how critical they are: a full inspection, oil analysis, vibration checks, refrigerant-leak detection and a report after each visit. Call 16062 for details.
Our data-center chiller is down — how soon can a technician come?
We do not promise a fixed arrival time: report it on 16062 at any hour; visits run daily 9 AM–9 PM at the earliest available slot for your area. Until the technician arrives, note the codes and alarms on the screen and avoid repeated resets.
Our factory chiller is down and production has stopped — how long will the repair take?
The time is set after the inspection, depending on the fault and parts availability: fixing a sensor or a small leak is much quicker than replacing a compressor or condenser tubes, which can take days. The technician gives you the expected time together with the quote.
Do you install a new chiller for a new factory or hotel?
New installations and complete projects are assessed after a site survey — call 16062 and we will confirm whether the project is within the scope of our services.
Do you perform vibration analysis and preventive maintenance?
Yes — vibration analysis picks up bearing damage, misalignment and imbalance early, thermal imaging reveals electrical hot spots, and oil analysis detects metal wear. The results go into a report that helps you plan maintenance before a fault grows.
A chiller has a refrigerant leak — how is it repaired?
R-134a and R-1234ze are expensive and harm the environment, so leaks come first. Inspection: an electronic leak detector, UV dye and a pressure test. Repair: locating the leak (usually a tube in the evaporator or condenser, or the compressor's mechanical seal), repair or replacement, a pressure test, evacuation and recharge. We record the refrigerant added in the visit report.

What is the expected lifespan of a chiller?
Usually 20–25 years or more with regular maintenance, depending on the type, the duty and the quality of water treatment; neglected maintenance shortens it considerably. The refrigerant is not replaced on a schedule — it is only topped up if there is a leak.
Do you offer eddy-current testing for the tubes?
Yes — eddy-current testing detects pitting and cracks in evaporator and condenser tubes before they leak, and is useful for critical or older chillers. Afterwards you get a report on the condition of the tubes and a recommendation to plug or replace damaged tubes where needed.
