Rooftop air-cooled chiller with compressor sets

What determines chiller maintenance fees?

YOİ Mühendislik technical team4 min readMaintenance and fault guideOctober 29, 2026
In shortThe chiller maintenance fee is determined by capacity, compressor type and count, whether it is air- or water-cooled, the scope of condenser cleaning, additional work such as oil analysis, the age and condition of the unit, access, and contract length. When comparing quotes, before looking at the price, check whether the scope is written out item by item.

Factors that set the chiller maintenance price

FactorWhy it matters
Capacity and number of circuitsEach refrigerant circuit and compressor is measured and checked separately.
Compressor typeScrew and centrifugal compressors have oil systems and additional checks.
Air / water-cooledFor air-cooled units coil cleaning stands out, and for water-cooled units tube cleaning and cooling tower water checks.
Condenser cleaningThe degree of fouling and the method (chemical, mechanical) determine the labor.
Additional workOil analysis, oil and filter replacement, refrigerant leak test, winter protection.
Age and condition of the unitFor units that have gone without maintenance, the first maintenance takes longer.
Access and working hoursRooftop, crane, continuously running processes or after-hours work.
Contract and cityIn an annual contract, intervals and priority response are planned; outside Ankara, the team plan is reflected in the price.

We deliberately do not give figures in this article: prices vary greatly with the number and type of units, access and city, and written figures quickly go out of date. If you send us your list of units, we prepare a written, itemized quote.

Written quote for chiller maintenance

Send us the chiller brand, model, capacity and address; we will prepare a quote with a clear scope.

What the quote must state in writing

We explained the step-by-step maintenance content in our article how chiller maintenance is done. If you have more than one unit, an annual maintenance contract usually gives a more predictable cost.

Frequently asked questions

How much does chiller maintenance cost?

Because it varies with capacity, compressor type, the scope of condenser cleaning, additional work and city, we do not give a fixed figure; we prepare a written quote based on the unit information.

What should I look for in a chiller maintenance quote?

Make sure the measurements to be taken, the condenser cleaning, the oil check and the report contents are written down.

Is an annual maintenance contract more economical?

For facilities with multiple units and where uninterrupted operation is needed, intervals and fault priority are planned, so overall it is more predictable and often more economical.
