- A RAV4 Hybrid owner was quoted $6,600 for HVAC repairs.
- New OEM HVAC units cost thousands before labor or taxes.
- Used parts cut costs, but labor charges still remain steep.
When you buy something like a Toyota RAV4 Hybrid, you probably expect reasonable ownership costs. It’s practical, efficient, and about as mainstream as it gets. What you don’t expect is a $6,600 repair bill for something described simply as an “airbox.” Yet that’s exactly what one owner recently encountered.

Let’s focus first on the nomenclature. Airbox sounds like the plastic housing in an engine bay that collects outside air, holds the air filter itself, and directs that air into the engine intake. Sadly for this RAV4 owner, that’s not what his dealer was talking about.
What Is An Airbox, Really?
Instead, it’s a massive plastic unit buried behind the dashboard, and it contains the heater core, the evaporator core, blend doors, and actuators. As one might expect, replacing it is no small feat.
The OEM HVAC Unit Case Assembly (part number 87050-42720) for the 2018 RAV4 is listed through Toyota parts channels at roughly $2,200–$2,500 before markup, depending on the retailer. That covers only the plastic housing and internal components, with no labor included. In this situation, it’s the labor that really drains owners’ wallets.

A used version of this part is sometimes available on sites like eBay for well under four figures. Sure, there are inherent risks in buying a used part for a component you hope to replace only once, but hey, a savings is a savings. What sites like eBay or businesses like a junkyard can’t do is swap the part for you.
The Real Cost Lies In Labor
As many commenters on the Reddit post where the owner shared his story pointed out, the dash has to come out for this job. That simple fact is enough for most folks to throw their hands up.
Let’s say, though, that this owner had the skills to do the job. That still doesn’t account for the likely need for evacuation of the A/C system prior to the job and then refilling it and checking it for leaks afterwards.
Granted, plenty of older cars have similarly difficult-to-get-to heater cores behind their dashes. It’s just very clear in this situation that plenty of owners have no idea about the potential for a four-figure bill waiting to show up from behind their dash.
