Performed inspection in heating. Found a high external static pressure and homeowner brought up unbalanced temperature in rooms. I offered an appointment with one of our efficiency specialists but declined at this time and will wait to see if situation worsens. I have also recommended a less restrictive option for filter replacements as the current one is a bit restrictive and is adding on to the system working harder. There are allergies known of within home so I offered an alternative, an air purifier system. Information has been attached.
