Horizon’s heating repair service in Johnston runs the same playbook as our AC repair: diagnose first, quote in writing, fix it on the first visit. Our techs are trained on every common heating system in RI’s housing stock — gas furnaces, oil furnaces, gas and oil boilers (steam and hydronic), heat pumps, and ductless mini-splits. Johnston is a heavy mix of bungalows and ranches built between 1940 and 1980, typical of the inner suburb ring. Most homes here are on natural gas with original or first-replacement forced-air systems.
Each truck stocks the most common heating repair parts — igniters, thermocouples, gas valves, zone valves, circulators, control boards, and aquastats. That’s why 90%+ of heating calls finish same visit. If we do need a special part, we order it overnight and waive the second trip fee — no extra charge for our shipping problem.
During cold snaps when every HVAC company in Rhode Island is slammed, we prioritize no-heat calls over comfort tune-ups and we run an after-hours emergency line for nights and weekends. Emergency surcharge is a flat $150 on top of the standard repair quote — most customers find that cheaper than waiting until morning at single-digit temps.
