What determines fan coil maintenance fees?

YOİ Mühendislik technical team4 min readMaintenance and fault guideOctober 29, 2026
In shortThe fan coil maintenance fee is determined mostly by the number of units, the fan coil type (especially concealed ceiling), access to the units, the scope of maintenance (filter only, or including coil washing and drain), and whether the job is one-off or under an annual contract. For a proper comparison, the scope of the quote should be written out item by item.

Factors that determine the fan coil maintenance price

FactorEffect on price
Number of unitsAs the quantity increases, the cost per unit generally falls; the team and travel are used more efficiently.
Fan coil typeConcealed ceiling ducted units require opening the ceiling hatch and more labor; wall and floor types are easier.
AccessHigh ceilings, the need for scaffolding, after-hours work, and an occupied office or hotel room layout extend the time.
ScopeThere is a big difference between filter cleaning only and comprehensive maintenance including coil washing, drain clearing, and motor and valve checks.
MaterialParts such as filter replacement, drain pump and capacitor are priced separately.
Condition of the unitUnits left unmaintained for a long time, with coils covered in oil and dust, require more work.
ContractIn an annual contract, intervals and priority fault response are planned, so the unit cost differs from a one-off job.
CityFor jobs outside Ankara, the team's travel and accommodation 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in this article: prices vary greatly with the number and type of units, access and city, and written figures quickly go out of date.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 fan coil maintenance

Tell us the number of fan coils, their types and your address; we will prepare a quote with a clear scope, item by item.

Questions to ask when comparing quotes

The cheapest quote with an unclear scope may mean only wiping the filters. We described the content of maintenance on our fan coil maintenance page and the step-by-step procedure in our article how fan coil maintenance is done.

When does an annual maintenance contract make sense?

If there are dozens of fan coils, a chiller and air handling units in a building, an annual maintenance contract that brings everything into one plan reduces both the risk of faults and the management burden. For public institutions, see our page on tenders and corporate contracts.

Frequently asked questions

How much does fan coil maintenance cost?

We do not give a fixed figure because the price varies with the number of units, type, access, maintenance scope and city. We prepare a written quote based on your unit list.

Is filter replacement included in the fan coil maintenance price?

It varies by quote; filter cleaning is usually part of maintenance, while the cost of a new filter is stated separately. Ask for this to be in writing in the quote.

Is one-off maintenance or a contract more suitable?

One-off maintenance may be enough for a small number of units. For many units and central systems, an annual contract guarantees the intervals and fault priority.

How often should fan coil maintenance be done?

Filter checks every few months depending on use; comprehensive maintenance is usually done once a year or at the start of the season.
