Ductwork repair and installation in Chicago Heights
If one room is always cold and another is always warm, the problem may not be your furnace or air conditioner at all. Mountain Top repairs and installs ductwork across Chicago Heights and the South Suburbs.
Ducts are the part of the system nobody thinks about until something goes wrong. Leaks, crushed sections and poor layouts all waste the heating and cooling you are paying for, and they make your equipment work harder than it should.
Why customers choose us for duct work
Check the ducts before you replace the equipment. A new furnace connected to bad ductwork will still give you uneven rooms. We inspect your ducts, explain what we find and repair or replace only what needs it. Because the same licensed crew handles your furnace and AC, we can see how the whole system fits together.

How do I know if my ducts are the problem?
Uneven rooms, weak airflow, noise and dust around the vents are common signs. A technician can inspect the ducts and tell you what is going on.
Should I fix the ducts before replacing my furnace or AC?
Often, yes. New equipment on poor ductwork will not deliver the comfort you are expecting. We check the ducts first and tell you what, if anything, needs work.
Can you add ducts for an addition?
Yes. We install and modify ductwork for additions and new layouts. Sometimes a ductless mini-split is the better fit, and we will tell you if so.
