Tri State Engineering

NEGATIVE 1 IS MORE ACCURATE!
STRONGLY RECOMMEND AGAINST EVER USING TRI-​STATE ENGINEERING LOCATED IN CHICAGO!
I have submitted a complaint to the Illinois Atty General Consumer Fraud division. Tri-​State Engineering of Chicago was recommended by GE to repair my warranted zone line unit at their facility.
They removed my unit from my residence to take back to their shop. Feliz Lopez (owner?) strongly recommended that they clean it as long as they had it in-​house. The cost quoted was $ 150. I agreed.
A unit was returned 3 weeks later. I provided payment for the quote to clean the unit directly to Felix Lopez. At that time, I stated that the unit seemed very loud, did not fit back into the spot correctly and wasn’t working like I expected. Mr. Lopez made some excuses and left.
I had suspicions that the unit returned WAS NOT the original! Identifying tags and serial number stickers were swapped out! After 8 weeks, the matter was settled with a new unit replacement.
Yet, the matter of my payment of $ 150 to clean the original unit was NOT settled. I contacted Mr. Lopez twice requesting the return of my $ 150. The second time, he got very angry, used intimidation tactics, threatened to interfere with the warrantee on my new unit and project his fraudulent behavior upon me, unless I dropped the matter of Mr. Lopez returning my $ 150. He said he would not return my funds and immediately hung up the phone.
FELIX LOPEZ ACCEPTED $ 150, DID NOT PERFORM THE SERVICE FOR WHICH HE WAS PAID AND REFUSED TO REIMBURSE ME, THE CUSTOMER! The integrity, character and business practices of Tri-​State Engineering is called into question.
I STRONGLY RECOMMEND AGAINST EVER USING TRI-​STATE ENGINEERING LOCATED IN CHICAGO!
