Summary

[Installation company] offers a market-conform quote for a Samsung Multi Split air conditioning system (5 kW) including installation for €3991 incl. VAT. The technical specifications are well substantiated and the warranty conditions are clear. Two points of attention require action before you agree: the missing payment terms and the open-ended additional-work provision without a cost cap.

Average score
⚠️ Our recommendation: Renegotiate first

The quote from [Installation company] is market-conform on price and the warranty conditions are solid, but two risks must be resolved before you sign. The most serious risk is the open-ended additional-work provision: the quote allows [Installation company] to add extra costs during work preparation without a maximum amount or a cancellation right for you. In addition, the payment terms and the general terms and conditions are missing entirely — request both and have an additional-work cap (e.g. max. €250 without your written approval) recorded in writing. Once these two points are resolved, this is an acceptable quote to sign.

Findings

Clear price breakdown
The quote clearly itemises product (€2320), installation (€1061), VAT (€710) and discount (€100). The total price of €3991 incl. VAT is easy to read.
Strong warranty conditions
5-year product warranty on the Samsung system and 2-year installation warranty, under which [Installation company] also steps in if the manufacturer fails to meet its obligations.
Good technical specifications
Brand, model, capacities (2,5 + 3,5 kW), SCOP (4,6) and energy label (A++) are stated. A sufficient basis for comparison.
Validity date present
The quote is valid until 03-10-2025, which allows sufficient time for comparison and decision-making.
Market-conform total price
€3991 incl. VAT for a Samsung Multi Split 5 kW including installation falls within the usual market range of €3500–€4500 for comparable systems in the Netherlands.
Company registration and VAT number missing
The quote does not state a Chamber of Commerce (KVK) number or VAT number for [Installation company]. Verify the legal entity and, on agreeing, request a VAT invoice that meets the legal requirements.
Payment terms entirely absent
No payment schedule, payment term or deposit arrangement is included. It is unclear whether you pay before or after installation. Request this explicitly before agreeing.
Pipework beyond 10m: no price
Pipework is included up to 10 metres. If more metres turn out to be needed during work preparation, costs will be added without any rate or cap stated in the quote.
General terms and conditions not attached
You agree by email to general terms and conditions that were not sent along. Request the T&Cs and read them before you sign — in particular the liability clauses and the additional-work procedure.
Open-ended additional work without a cap
The quote states that 'necessary work' may be added during work preparation. There is no maximum amount, no additional-work procedure and no period within which you can cancel if the extra costs turn out too high. This gives the provider unilateral room to increase the final price.
F-gas/STEK certification not confirmed
For installing split air conditioning systems containing refrigerant, a STEK-certified installer is legally required in the Netherlands. The quote does not mention this explicitly. Request the STEK certificate number of the engineer carrying out the work.
