Sound familiar? Here is what Johnston homeowners tell us when they call:

  • Furnace stopped working in the middle of a cold snap and the house is dropping a degree an hour.
  • The boiler is making banging noises you've never heard before and you don't know if it's safe to keep running.
  • Heat is on but the rooms upstairs are freezing — and you've been told it's 'just how the house is.'
  • You smell something burning when the furnace kicks on and you're not sure whether to turn it off or call.
  • You called the company that installed it five years ago and got voicemail — twice.

Here is how Horizon HVAC solves it in Johnston:

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.

Pricing: Most Johnston heating repairs run $200-$600. Common pricing: igniter $200-$280 · zone valve $300-$450 · control board $400-$700 · circulator pump $350-$600 · thermocouple $180-$240. $50 diagnostic, waived on approval.

Why Johnston Homeowners Choose Horizon HVAC

Same-Day Dispatch

Call before 2pm and we have a tech at your Johnston address before dinner in 90% of cases. Our techs route from the closest available truck — not from a central dispatch hub — which is why we hit same-day even during heat waves and cold snaps.

Flat-Rate Pricing in Writing

Every job in Johnston gets a written flat-rate quote before any work starts. No hourly drift, no parts upcharges, no surprise add-ons at the invoice stage. You approve in writing or we leave — no hard sell.

Licensed and BBB A-Rated

RI license #00007430. Fully insured (general liability + workers comp). BBB A-rated. Every tech is a full-time Horizon employee — background-checked, drug-tested, badged. We never subcontract.

Premium Brands, Honest Recommendations

Factory-trained on Mitsubishi, Bosch, Carrier, Trane, Rheem, Viessmann, and most major brands. We recommend the right system for your house and budget — not the brand we’re trying to push this month.

What You Get When You Book Horizon for Heating Repair

Furnace, Boiler, Heat Pump — All Covered

Gas, oil, hydronic, steam, heat pump, mini-split. If it heats a Johnston home, we service it. Most techs train across systems so you don’t get a mismatch on dispatch.

Brands We Are Factory-Trained On

Cold-Climate Heat Pumps: Mitsubishi Hyper-Heat, Daikin Aurora, Bosch IDS

How to Tell If Your Johnston Furnace or Boiler Needs Repair (5-Step Self-Check)

Before you call Horizon for heating service, run this 5-step self-check. Some no-heat calls have a $0 fix; others need a tech. Here is how to tell:

  1. Step 1: Check the thermostat
    Confirm thermostat is set to HEAT, not OFF or COOL. Set target temperature 5 degrees above current room temp. Replace thermostat batteries if the screen is dim. If you have a smart thermostat (Nest, Ecobee), confirm Wi-Fi is connected — some lose programming when offline.
  2. Step 2: Check the breaker and switch
    Find the electrical panel. The furnace breaker should be ON. Also check the emergency furnace switch — usually a red switch on the wall next to the furnace or at the top of the basement stairs. It should be ON. If the breaker is tripped, flip it OFF then ON. If it trips again, stop and call Horizon.
  3. Step 3: Check the air filter (forced air systems)
    Pull the return filter. A clogged filter trips the high-limit safety switch on most modern furnaces and shuts the furnace down to prevent overheating. Replace the filter, wait 30 minutes for the system to reset, then test heat.
  4. Step 4: Check the gas supply (gas systems)
    Look at the gas valve at the furnace or boiler. The handle should be parallel to the gas pipe (open). If it is perpendicular, turn it parallel. Also confirm other gas appliances work — if your gas stove is also out, the gas service is interrupted (call National Grid: 1-800-870-1664).
  5. Step 5: Check for error codes (modern systems)
    Most modern furnaces have a small LED on the control board that flashes a diagnostic code. Count the flashes (e.g., three flashes = pressure switch fault). Write the code down before calling — it cuts diagnostic time in half. Boilers often display codes on a small LCD.

Still no heat? Call (401) 425-9879. Most Johnston heating repairs run $200-$600. Same-day dispatch even during cold snaps.

What Johnston Homeowners Say

★★★★★

“Boiler died on a Sunday in January. Horizon's emergency line picked up, dispatch came out within two hours, had the part on the truck. They didn't gouge us on emergency pricing either — added the standard $150 surcharge and that was it.”
