Gas & Propane Wall Furnace Repair

A wall furnace may stop heating because the thermostat is not calling for heat, ignition has failed, fuel is unavailable, or a safety control has interrupted operation. Start with the thermostat's normal user settings and any known utility outage. Keep the front grille clear. A pilot flame or a clicking sound does not identify the failed component. If heat does not return, request diagnosis. Do not open the burner compartment, adjust a gas valve, bypass a safety switch or repeatedly try to restart the heater.

Repeated pilot loss can involve the pilot assembly, a thermocouple or thermopile on applicable models, gas supply, venting or a safety-control problem. Replacing a sensor without checking the cause can leave the underlying fault unresolved. Stop repeated relighting and arrange an inspection. Tell Heco whether the pilot goes out immediately or after the main burner runs. If you smell gas, leave and call emergency services and your gas provider from a safe location.

The pilot and main burner have different jobs. A visible pilot does not prove that the thermostat circuit, millivolt generator, valve or safety controls can operate the main burner. Check only normal thermostat settings and report whether the burner ever starts. Do not bridge thermostat wires or jump terminals. Heco can evaluate the applicable control circuit and combustion system after identifying the exact model.

Heco accepts service requests for natural-gas and propane (LP) wall furnaces. Include your city or ZIP, brand, full model number and fuel type so equipment support and coverage can be confirmed. If a propane tank has run empty or supply was interrupted, contact the propane provider about restoring service and required safety checks. Do not attempt to purge a gas line or change the regulator yourself.

Only when the manufacturer specifically permits conversion of that exact model using its approved parts and instructions. Some appliances cannot be converted. Natural gas and propane require different fuel settings and may require different components. A qualified professional must verify the rating plate, approved kit, gas pressure, combustion and venting. Never connect a heater to the other fuel or substitute an orifice based on appearance.

Some standing-pilot gravity or millivolt wall furnaces can supply heat without household electricity. A powered blower, electronic ignition or other electrical control may still require power. Check the exact model manual; do not assume every gas or propane wall heater works during an outage. Never bypass an electrical or safety control to force operation.

It depends on the design. Many gravity wall furnaces do not use the same replaceable filter as a central forced-air furnace. Some fan-assisted models have manufacturer-specified filtration or cleaning requirements. Check the manual before adding filter material over a grille. An improvised filter can restrict airflow and affect safe operation. Ask Heco to identify the proper maintenance requirements for your unit.

A ductless mini-split may be an alternative when you want heating and cooling, but the decision needs a site evaluation. Heco reviews room layout, heating load, electrical capacity, outdoor-unit placement, drainage and installation requirements. A like-for-like wall furnace replacement also requires venting, fuel, clearance and applicable permit checks. Compare the complete scope and operating costs rather than equipment price alone.

The $49 repair service fee is for first-time customers only. Repair charges are separate and depend on diagnosis, parts, access and equipment condition. Heco explains the findings and proposed repair charges before authorized work proceeds. Include the model and symptoms when requesting service; submitting a request does not confirm an appointment or a final repair price.
