Volvo V60 Aircon Blowing Warm: How We Traced It to the Evaporator Coil

The owner drove in with a Volvo V60 whose aircon had stopped blowing cold. It was still pushing air through the vents, but the air was warm, not cold. In the Singapore heat that turns a short drive into a sweat-soaked one, windows down, fan on full, and still no relief.

Low refrigerant is one common reason a system loses its cold, and refrigerant does not disappear on its own: it leaks. Topping up without finding where treats the symptom, not the fault. The ask was simple: find the real fault and fix it properly so the cold stays.

We started by checking the whole aircon system rather than just topping it up. The air from the vents was warm, and the system was not performing the way a healthy, sealed one should.

The diagnosis led to the evaporator coil behind the dashboard, where the cold is actually made. The expansion valve sits right there and controls the flow into the evaporator, so it made sense to replace both in the same operation rather than risk opening the dashboard twice.

This is the part owners do not always like to hear, because it means the dashboard has to come out. But there is no shortcut: when the fault sits in the evaporator, no amount of regassing keeps the car cold.

We did the job properly rather than patch it with a regas alone.

• Removed the dashboard to reach the evaporator buried behind it.
• Replaced the evaporator cooling coil with a quality replacement part.
• Replaced the expansion valve while we were in there.
• Vacuumed the system to pull out moisture and air, then regassed it with the correct refrigerant.
• Tested the aircon until it was blowing properly cold, then refitted the dashboard.

We kept the owner updated as the job went. Because the dashboard has to come out and the system needs testing after reassembly, this job takes the time it takes, and we did not rush it: a rushed aircon job that has to be opened up again helps no one. The aircon blows cold again, and the repair carries at least a 6-month warranty.

What a job like this costs depends on the model and how much labour it takes to reach the evaporator. This job came to $1,250 including installation, which covered the evaporator cooling coil, the expansion valve, and the vacuum and regas, with at least a 6-month warranty on the repair.

Most of the cost on this kind of job is labour, not the part. Getting the dashboard out and back in safely takes time and care, especially around the airbag and wiring. That is why an evaporator repair costs more than a straightforward regas or a condenser fix that is easier to reach. We always check the full system and quote firmly before any work begins.
