phalaenopsis hasnt bloomed in ~3 years

[lkatwest]

In early 2015 i received 2 orchids as a gift. They were blooming when i received them. They were both in moss so as soon as the blooms died i planted them into bark. One was sitting in an east window and another in a west window. However now they we both in west windows as we recently moved to a new house. I water them once every 7 days by letting tap water run through the pot for 30 seconds, then i fill the sink and plop them in with some fertilizer for 5 minutes. I drain any water from the pots and sit back by the sill. Anything I could do differently to get them to bloom??
