Our Home Comfort Specialists know the ins and outs of each and every furnace and are able to guide you through the selection and installation process with ease.


No ducts? No problem! While many homes are equipped with furnaces to address their heating needs, boilers are still a valid option for your heating system. A boiler utilizes radiators throughout the home instead of duct work to distribute heat and comfort. We are proud to offer Well McClain, Utica or Dunkirk boilers, known for their durability, efficiency, and reliability.

Air Quality

Cracked skin, static electricity, sore throats, and hardwood damage are all the result of excessively low humidity levels within the home. Luckily, RJS Heating and Cooling can put the moisture back in the air with the help of a whole house humidifier and Aprilaire technology.

Water Heaters

There are few things more inconvenient than getting into the shower and finding that there is no hot water in the home. Before you suffer through an icy cold shower, call RJS Heating and Cooling and get your hot water heater repaired within a matter of hours, not days! If your hot water tank has called it quits, consider having RJS Heating and Cooling replace your old tank with a new high-quality Rheem water heater.

Temperature Control

Your thermostat controls half your energy bill – more than appliances, more than electronics. So shouldn’t it help you save energy?
