A Reliance technician came to check what is wrong with the air condition in our 6 yr old house in London. He came and told us that the problem is a refrigirate leak that cost 1500 + HST. He said the problem is in level 7 highest level that need major repair. We called another service from another company and the guy came and said AC is running but not removing humidity. He said refrigirate level is ok. He just activated the HRV and AC works fine. He charged me 80 + tax in this service. Not to mention Reliance charged us to 99+ HST ON WRONG DIAGNOSTIC REPORT. Reliance is scammer. Always get second opinion.. their technicians are salesman.
