Respect the room layout when improving comfort
East Sacramento requests are routed as a Sacramento neighborhood, not an independent city office. For an addition, converted room or isolated comfort problem, describe how that space connects to the existing duct system before assuming the central equipment is undersized.
A ductless option can be compared with duct corrections or central replacement. Discuss the indoor-unit position, condensate route, outdoor clearances and electrical work so appearance and access are part of the proposal from the beginning.
For rooftop units, bring additions and targeted comfort into the scope discussion. A failed component may justify repair; repeated faults or a major failure can justify a scoped replacement comparison. Include building interfaces and access costs so proposals cover more than the rooftop cabinet.
