Arrived onsite for no heat from a couple radiators; possible steam air vent issue. Also discussed home’s air quality during the winter. Home may benefit from circulating the air using the air conditioner’s fan on or circulator settings. Also may benefit from adding indoor air quality solution for both air handlers. This will help provide medical quality air quality inside the home by removing and killing organic materials. Will provide an estimate for indoor air quality solution. And an estimate for the installation for the back room mini split.
