Galloway Lane SW in Concord
According to our home builder (Ryan Homes) we need a dehumidifier in our finished basement (2 rooms, about 500 sq') due to moisture just above the floor in a 3-4' section, and an A/C ceiling vent showing moisture and minor staining around it. We are also concerned why it is several degrees warmer upstairs than in the basement or main floor. If your Company does it, we are also interested in semi annual inspections of our heating and cooling systems to make sure they are functioning optimally. Thank you.
Lomax Ct SE in Concord
I have recently had an insulation installed in my attic from EnergESquad. The same thing fire fighters use to protect themselves. The same lining in pizza home delivery bags. But I can no longer find them. Can you help?
Wind Song Ct in Concord
I go through this every summer - the AC can not keep up with the outside heat - especially in the front part of the house (uncomfortable). I want an energy (system) evaluation and see what we can do to make home more comfortable.

Amana Heat Pump system from (2012) can not keep certain parts of the house warm at all. Not sure if the ducts have been sized properly or if my ducts are leaking. Or even if the unit is the right size for my house.
