SIGNS / 01
Store air conditioner issues to look out for
Symptoms and equipment conditions for store air conditioners vary depending on the model, installation environment, and store operations. The examples below can help you organize the situation when making an inquiry. If there is a safety risk, follow the store or facility’s safety procedures before attempting any work or taking photos.
Odors or black residue when the unit is blowing air
The areas to check, such as the filter, interior, and drain area, vary depending on the unit's condition. We will clarify when the odor occurs and where dirt is visible.
Heating or cooling is not working effectively
Factors other than dirt, such as settings, operating conditions, or equipment problems, may be involved. We check the model and displayed information rather than assuming cleaning will resolve the issue.
Water leaks or error displays
If there is a water leak or an error, follow the store's safety procedures and the instructions of the manufacturer or facility manager. The displayed code and details about when the issue occurred can be helpful when seeking advice.
BEFORE CONSULTATION / 02
Please provide whatever information you can before your consultation.
For store air conditioners, please share what you know about the manufacturer, model number, unit count, and the locations of the indoor and outdoor units. If an on-site check or additional documents are needed, we’ll let you know after discussing the situation.
- Manufacturer, model, quantity, and indoor and outdoor unit locations
- Details of odors, poor performance, leaks, unusual noises, or error messages
- Ceiling height, installation type, inspection openings, and work space
- Preferred work hours that can help minimize disruption to business operations
Disassembly cleaning, electrical and refrigerant system inspections, and parts replacement are separate tasks. For work involving required qualifications, equipment, or manufacturer procedures, we will confirm the scope and who will perform it in advance.
We’ll advise whether work on store air conditioners is possible, along with the method, schedule, and cost, after checking the equipment’s condition and the store, regional, contractual, and facility requirements.
QUESTIONS / 03
Frequently Asked Questions
Can I consult you even if I don't know the model?
Yes. Please tell us what you can about the indoor unit's appearance, installation location, number of units, and any issues. If a photo of the nameplate is needed, we will first confirm that it can be taken from a safe position and then advise you.
Can cleaning fix water leaks or error displays too?
This depends on the cause, and cleaning alone may not resolve the issue. If there is a water leak or an error, prioritize safety by refraining from use in accordance with the store’s procedures, and check whether inspection or repairs are needed.
