DEFECTIVE UNITS / PARTS / ACCESSORIES-REPAIR OR REPLACEMENT

Out of thousands of units sold every year, there may be an occasional instance your product does not operate 
properly. Reasons of but are not limited to: 

manufacturing, installation, operation, maintenance and 

knowledge of operator

The defects might be found before/ during installation or in the operation of the unit. Defects can be in the form 
of blown fuse(s), defective control board(s), damaged remote control, loose or missing screws, etc. These 
defective parts can be replaced easily.

Some functions of our units are different from what are typical in traditional split type air conditioning and heat 
pump systems and similar systems made by other manufacturers. These are not defects. Take some time to 
learn the functions of your unit. We will be happy to assist you with any questions you may have concerning the 
functions of your new unit.

1. 

Part repair or replacement after trouble-shooting: 

 This is the most common and generally the easiest and 

    most economical way for all parties, since the problem and all part needs can be accurately and completely     
    identified. 

* Your technician calls our technical support line, from your job site, after checking your units and getting all the information 
  ready.
* Our technical support will go through several steps, over the phone or through email, with your technician, in order to help 
  identify and resolve the problems. Normally wiring correction, piping correction, part repair/ replacement will resolve the 
  problems. 

* Your technician will then need to verify and confirm the problem(s) before YMGI can ship out the replacement part(s). 
  Inaccurate or incomplete troubleshooting or part replacement will delay the repair. YMGI technical support will only speak 
  with a licensed/certified technician in regards to the repair of your unit.  In our experience this saves time and money for 
  all parties involved.

Your technician is the only person to perform any physical checking, trouble-shooting and replacing of any 
defective part(s) for your units. Our factory technical support is just a help.  

YMGI provided no labor warranty 

on the products.

 

2. Unit/part repair at our workshop(s):

  Due to the limitations of our technical support not being at your job site, 

    or your technician's experience with our product, the problem may not be resolved as quickly as would be 
    desired.

 

If the problem is still not resolved after attempts between your technician and our technical support, 

    you can elect to have the unit repaired at our facility.  If this step is chosen:

1) YMGI will send to you the 

Customer Request to Ship Products to YMGI Service Center for Inspection and Repair, 

    and Authorization to Charge 

form.

2) You will review the form and fill all fields appropriately, sign and send back to the YMGI Group.
3) Once the form has been completed and sent back to YMGI, remove the units and ship back to YMGI.

Please make a note describing the problem and communication history, if possible. Our technicians will check the 
units and find the problem(s), repair the issue(s), and ship the unit back to you following the conditions set forth in 
the signed repair agreement. All unit removal and re-installation is done at your cost

 

and must be done by a 

currently valid licensed HVAC technician.

3. Unit replacement:

 Only applies to those defects reported within 30 days of original purchase date

 

and if all 

    necessary warranty paperwork had been received and approved. This option applies only if the above steps 
    cannot resolve the problem(s). Either indoor or outdoor unit replacement is available, based on the actual need, 
    at YMGI's determination. 

This option shall be the last resort

, due to refrigerant and wiring considerations. All 

    unit removal, re-installation and shipping cost are the responsibility of the customer.

 

YMGI maintains the final 

    authority as to unit replacement.  Replacement will be made with the same model only.  Alternate units will be 
    treated as a new order. 

Returning Replaced Defective Units/Parts/Accessories After Unit Repair: (

Only applies to steps 1&3 above)

1) Repack the replaced unit/ part /accessory in the box which contained the replacement part. 
2) Parts can be boxed for UPS, FedEx or equivalent ground service. Units shall be secured onto the skid on which the 
    replacement was shipped after placing into the

 

package from the replacement

 

product.

3) Ship 

all

 replaced products, to YMGI-designated location. You will be charged if YMGI does not receive the replaced parts.

Standard factory warranty does not cover the cost of materials and labor that are incurred at your site. 
There will be no cost for the replacement unit, if YMGI determines the defect is manufacturer related. 
Replacement will be made with the same model,

 

only.  Alternate units will be treated as a new order.
