Boiler, Radiator & Radiant Heating Service

Boiler Experts for Older North Shore Homes

Walk down almost any street in Evanston, Rogers Park, Wilmette or Skokie and you’ll find homes that have heated with boilers and radiators for generations. Boiler systems are comfortable, quiet and long-lasting, but they need a technician who understands them. Many newer HVAC companies only know forced air. Gartner has worked on boilers for more than 40 years.

Steam vs. Hot-Water Systems

Steam systems heat water to steam, which rises to the radiators, and they usually have a sight glass showing the water level. Hot-water systems circulate heated water with a pump and are often easier to zone. Both can be maintained for many years. When replacement time comes, Gartner will explain whether to keep the radiators with a new high-efficiency boiler or to add ductless or ducted systems for cooling at the same time.
