Comment: Sweaty ducts Attic fan always on is summer

Project Location: Sky Blue Ct, Alexandria, 22315

Comment: Hot attic and old insulation. Currently upstairs where bedrooms are is very warm. And have to keep lower levels too cold so upstairs is comfortable. Also have an issue where ducts work is sweating between the first and second level, not sure why.

Project Location: Coventry Rd, Alexandria, 22306

Comment: We purchased our house last year and have really enjoyed it for the most part. We noticed last summer that our bedroom on the second floor (two story cape cod style hose) really struggled to get cold air, and it is the same this summer. It is the typical hottest room in the summer and coldest room in the winter. I have a feeling that it is due to poor insulation in an older house. The HVAC system is decent, but it just doesn't quite cool off our bedroom. I would like to get an estimate to see what our options are. Thank you.
