WHY DOES YMGI GROUP REQUIRE INSTALLATION AND SERVICE TO BE
100% PERFORMED BY LICENSED OR CERTIFIED HVAC TECHNICIAN/
CONTRACTOR?
1) They have the training and experience to accurately and safely install and service your equipment.
The equipment runs with high-pressure refrigerant and oil and line-voltage. 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 problems occur on the unit that is fully installed by the licensed
or certified contractor, they have the training and experience to correct the problem more efficiently. A
technician(s) may be unwilling to repair an issue on a unit that they did not install. If you do find a technician
willing to perform the service, there is an increased possibility of higher service fees than normal, 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., requiring only licensed or certified professionals can install and service high
pressure HVAC equipment.
SUGGESTIONS, TO AID YOU IN HIRING AN HVAC CONTRACTOR:
1) Hire a currently, practicing, licensed/ certified HVAC technician/ contractor. Technicians, who are no longer
practicing (retired, etc.) in this field, may not have the updated knowledge or may lack experience on the
equipment you have purchased.
2) Hire a technician/ contractor who services customers in your local area and you are familiar with. Local
contractors have a faster response time and will be easier for you to determine if they are reputable.
3) Use only reputable licensed/ certified HVAC installation contractors/ technicians to prevent any unexpected
charges as a result from unethical business practices.
4) Check their references, to verify they are a good service provider to the general customers. N.A.T.E or A.C.C.A
certified technicians are strongly recommended.
5) Some contractors/ technicians may not feel comfortable about installing the equipment that you purchased for
them to install, and they prefer to purchase and install the equipment. You can contact YMGI directly to check
and see if there have been any contractors in your area who have installed our products or similar.
6) Ask for a detailed quote for the whole installation project. A flat rate quote is the safest contract for both you
and the contractor
7) Your local HVAC technicians may charge you on a project basis or on an hourly basis. To our general
knowledge and experience, a full single head installation may normally cost anywhere from $800 to
$1500 . These costs are estimates and your actual costs may differ due to job nature and location.
8) Number of hours can vary depending upon each individual situation, some factors are, but not limited to:
9) How difficult or complex the indoor unit is to be securely installed.
10) How difficult or how long the inter-connecting pipes and wires are to be installed.
