What that means for heating and cooling

Mostly older housing. About 71% of homes in Hillside were built before 1960, and 30% before 1940. Older homes often have hot-water or steam boilers with radiators, original chimneys and little or no ductwork. That makes boiler service, venting checks and ductless cooling common requests.
Mostly gas heat. About 80% of households heat with utility gas, 8% with electricity and 7% with fuel oil. With that much gas heat, annual combustion and carbon monoxide safety checks matter.
Some oil heat remains. About 7% of households still heat with fuel oil, so oil-to-gas or oil-to-heat-pump conversions come up.
Mostly houses. 62% of homes are single-family houses, and 32% are in two- to four-unit buildings.
Most households own. About 33% of households rent and 67% own. Homeowners are usually the ones deciding on repair versus replacement, and we give you the information to make that call.

New systems and replacements: free on-site estimate. We measure the space and look at the existing setup before quoting.
System not working right: a diagnostic visit has a fee, and the entire fee is applied toward the repair.
Larger jobs: financing is available, including for emergency system replacements.
Warranty: a labor warranty is standard on every replacement and new installation. Manufacturer equipment warranties carry their own terms, and we help you register the equipment.
