YMGI: Your Modern Green Idea 

 

 

 

 

11 

 

WHY DOES YMGI GROUP REQUIRE INSTALLATION AND SERVICE TO BE PERFORMED 100% 
BY CURRENTLY LICENSED OR CERTIFIED HVAC TECHNICIANS/CONTRACTORS? 

 

1. 

Expertise and Safety: 

They have the training and experience to accurately and safely install and service your equipment. The equipment 
runs with high-pressure refrigerant, oil and electrical current. The copper lines must be installed properly to prevent 
leakage and foreign substances from contaminating the refrigerant system. 

2.

 You will save money in the long run:

 

If  any  problem  occurs  with  the  unit  that  has  been  fully  installed  by  a  currently  licensed  or  certified 

technician/contractor, contact the original licensed or certified HVAC technician to evaluate the unit as they have 
the training and experience to correct the problem quickly and efficiently. A technician may be unwilling to repair 
an issue on a unit that they did not install. If you do find a technician willing to perform this service, there is an 
increased possibility of higher service fees, increased service visits, or delayed service from that technician. 

3. 

It’s the law!

 

The federal, state and/or local government and authorities have various governing laws or regulations, guidelines, 

ordinances, etc. These laws may require only licensed or certified professionals can install and service this type 
of high pressure HVAC equipment. 

 

SUGGESTIONS TO AID YOU IN HIRING AN HVAC CONTRACTOR: 

 

1.  Hire  a  currently  practicing,  licensed/certified  HVAC professional  technician/contractor.  Technicians,  who  are  no 

longer practicing (retired, etc.) in this field, may not have current technical knowledge or may lack experience on 
the equipment you have purchased. 

2.  Hiring a licensed technician to install your unit as a "side job" and not hiring a licensed HVAC company may pose 

possible risk. This may result in an incomplete or unsatisfactory installation, no guarantee for workmanship and 
lack of maintenance and further service to your unit. 

3.  Hire  a  technician/contractor  who  services  customers  in  your  local  area  and  one  you  are  familiar  with.  Local 

contractors have a faster response time and it will be easier for you to determine if they are reputable. 

4.  Use only a reputable licensed/certified HVAC installation professional to prevent any unexpected charges because 

of unethical business practices. 

5.  Check their references, verify they provide professional service for their customers. N.A.T.E or A.C.C.A certified 

technicians are strongly recommended. 

6.  Some contractors/technicians may not feel comfortable about installing equipment that has been purchased by 

someone other than themselves. They prefer to purchase and install the equipment themselves. You can contact 
YMGI directly to check and see if there are contractors in your area who have installed our products or any similar 
products. 

7.  Ask for a detailed quote for the complete installation project. A flat rate quote is the safest contract for both you 

and the contractor. 

8.  Local  HVAC  technicians  may  charge  you  on  a  project  basis  or  on  an  hourly  basis.  It  has  been  our  general 

experience; 

a full single head installation normally can cost $800 to $1500

. These costs are estimates, and 

your actual costs may differ due to your specific job requirements and installation location. 

9.  Number of hours can vary depending upon each individual situation, some factors are, but not limited to: 

  Difficulty or complexity of securely installing the indoor unit. 

  Difficulty or length of the inter-connecting pipes and wires to be installed. 

10. A successful installation is dependent on all these suggestions and all the necessary steps are followed. 
11. If the contractor(s)/technician(s) are experienced with the systems/brands you purchased. 

You might save on 

the installation cost, but remember to always ask for and verify references. 

12. The contracts should list and detail all work to be performed and the standards they will follow. Some contractors 

are willing to include a 1-year installation/service warranty at no extra charge. Check to see if this is an available 
option. If available, make sure it is included in the contract. 

13. Verify and confirm the installation is completed and all the unit functions have been tested and working properly. 

All items on the checklist should be checked and clearly marked in the warranty registration card/form, prior to 
paying the contractor in full. 

 

The cost of not having your unit professionally installed can be more expensive than the additional cost of hiring a 
certified contractor. Protect your investment and warranty eligibility by doing it right the first time.
