Aircon Not Cooling in Nagoya: Inspection and Repair
Lukewarm air or weak cooling does not automatically mean low refrigerant. We check settings, airflow, the outdoor unit and the refrigerant circuit. Actual Nagoya cases have needed very different work, from removing a clogged aftermarket filter to repairing a leaking pipe connection.
Different causes need different work
Before inspection: Stop use if there is a burning smell, severe unusual noise or a tripping breaker. Do not touch refrigerant pipes or electrical parts; note any error code for your enquiry.
Settings or obstructed airflow
Check cooling mode, temperature and the filter. Aftermarket filters or objects around the outdoor unit can restrict airflow. Share photos taken from a safe position.
Dirt inside the unit
A dirty fan or heat exchanger may call for cleaning. Weak airflow alone does not confirm dirt as the cause; the unit's operation also needs checking.
Low refrigerant or a unit fault
Lukewarm air and icing can warrant refrigerant-circuit inspection. Low refrigerant requires a leak check; component faults may need manufacturer service.
Price and what affects the total
Aircon repair (tax included)
from ¥15,000
Cleaning, refrigerant top-up, leak repair and replacement parts are different work items. Inspection findings determine what is needed and the total estimate.
Choose work after the findings and estimate are explained.
From enquiry to follow-up checks
- Confirm when cooling changed, airflow, error codes and previous refills
- Inspect operation, dirt and piping to narrow down the cause
- Explain cleaning, repair or manufacturer-service options and costs
Availability depends on the model, parts, address and schedule. We explain when manufacturer repair is more appropriate.

Questions before booking
Can I request a refill when the fan runs but the air is warm?
Yes, but inspection comes first. The cause may not be refrigerant shortage, and any shortage should be checked for leaks.
Should I replace a unit with weak cooling?
Compare the cause, age, parts availability and repair estimate with replacement and installation costs before deciding.
What if cleaning the filter does not help?
Do not disassemble the unit. Send the model, error code and photos of both units so the appropriate inspection can be discussed.
Send the symptom and photos first
Share your area, model label, what happens and when, and safe photos of both units. We cover Nagoya's 16 wards; nearby areas and visit dates are confirmed individually.
