Bill the Master Tech

 

If your supplier says:

That motor's 7 years old.
Part is no longer available.
We lose $$ on service!
EPA made me do it!
Parts at central warehouse, you'll get them next month.
We don't make parts for those.
We only do warranty work.
Our techs only fix late models.
No clue what's wrong! So we'll work time & material.

Baloney!!

NEW and Rebuilt units carry a 1 (one) year warranty. This is a supplier warranty. Most units have core value (included in price). Return shipping for cores is prepaid, if you have a repairable unit. MasterTech will remit the core credit after evaluation by the rebuilder.

PLEASE NOTE: OVERSEAS SHIPMENTS (INCLUDING HAWAII, ALASKA, & U.S. TERRITORIES) REQUIRE EXTRA SHIPPING CHARGES.
CORE CHARGES FOR THESE MOTORS ARE
NOT REFUNDABLE AND NO CORE IS REQUIRED. THE PRICE REMAINS THE SAME.
