Hydro-Air Systems in Providence, RI
A hydro-air system pipes hot water from your boiler to a coil inside an air handler, so the house heats through ducts while the boiler stays the heat source. The same air handler can carry an AC coil, giving one duct system for heating and cooling.

Boiler-fed air handlers that heat through ducts and add central air, common in New England homes. Typical cost in Providence runs $219 to $9,850, and the phone is answered 24/7 at (401) 598-2964.
Signs it is time to call
- Warm air never arrives while the boiler is clearly hot
- The air handler hums but rooms stay cool
- You want central air in a home heated by a boiler
- Hot-water coil leaks or a stuck zone valve at the air handler
Hot-water and steam heat are still the backbone of Providence's older housing, from East Side Victorians to triple-deckers in Elmwood, Pawtucket and Central Falls. These systems last a long time, but they depend on correct water levels, pressure, venting and air removal, which is where most of our boiler work starts.
What the work includes
- Check the zone valve or pump that feeds the hydronic coil
- Test the air handler blower, controls and coil temperature split
- Purge air from the coil loop and look for leaks
- Add an AC coil and condenser to an existing hydro-air handler
Hydro-air is common in Cranston, Warwick and East Greenwich homes built or renovated with attic air handlers fed by a basement boiler.

How the visit goes
- We start at the boiler: gauge readings, the sight glass or pressure, venting and the burner.
- Then we walk the system floor by floor, checking radiators, valves and zones that are not heating.
- You get the findings and the price before any repair, in plain language.

Hydro-Air Systems questions
What is a hydro-air system?
It is an air handler with a hot-water coil supplied by your boiler. The boiler makes the heat, and the air handler moves it through ductwork.
Why does my hydro-air blow cold air?
Usually the coil is not getting hot water because of a stuck zone valve, a failed circulator or air trapped in the coil loop.
Can hydro-air also cool the house?
Yes. An AC evaporator coil can be added to the air handler with an outdoor condenser, giving heating and cooling through the same ducts.
