Fighting high levels of humidity inside the house
I am worried about mold forming, and will be looking to purchase a dehumidifier ASAP. But I am trying to understand the big increase in humidity levels from last summer to this one.
1) we started work in our basement last month - for which the door to the cold room (located in the basement) was removed to allow for framing. This is still removed. Though I’ve asked the contractor if this would be the cause for the high humidity, and he doesn’t think so.
2) We have a VaNEE LT HRV unit which was set to intermittent (yellow) - should we be turning these off outright?
3) The windows have not been fogging up due to condensation
I’ve read anything over 50-60% is not good for the home, and really concerned about mold forming as a result. Do I need to have an HVAC contractor come and review what might be happening, and perhaps check for any early sign of mold?
