Mahwah Plumbing & HVAC FAQs
Our upstairs never cools even though the system runs constantly. Is a bigger unit the answer?
Rarely. Oversizing makes humidity worse. We run a heat gain calculation and check duct sizing and return air first, because in larger Mahwah homes the fix is usually zoning or ductwork, not tonnage.
Can you design a system for an addition or a whole-house renovation?
Yes. We have a mechanical engineer and an electrical engineer on staff, so we do custom system design with heat loss and heat gain calculations and handle the wiring for the install ourselves.
We have a finished lower level that is always cold. What are the options?
Often a dedicated zone or a ductless head is the cleanest solution, since the existing system was usually sized and ducted for the floors above before the lower level was finished.
