The furnace issues Plumbing Masters sees most are worn parts, faulty ignitions and airflow problems. These show up as a furnace that will not light, one that runs but blows cool air, or one that shuts off before the house warms up. Our technicians test each component, find the real cause instead of guessing, and explain the repair before any work begins.
It depends on the age of the furnace, how often it breaks down and what the repair involves. A single worn part on a newer unit is usually worth fixing. An older furnace that needs repeated repairs, heats unevenly or keeps raising your energy bills is often a better candidate for replacement. Plumbing Masters will give you an honest recommendation, not a sales pitch.
Common causes include a dirty or clogged filter, a thermostat set to fan instead of heat, a failed ignitor or flame sensor, or a gas supply issue. Start by checking the thermostat setting and replacing the filter. If the air is still cool after that, shut the system off and schedule a diagnosis so a Plumbing Masters technician can safely test the ignition and burners.
First check the thermostat, the furnace switch and your circuit breaker, then look at the filter. If the furnace still will not start, contact Plumbing Masters by phone or use the Schedule Now button to book a repair visit. If you smell gas, leave the house right away and call your gas utility before calling us.
It can. A cracked heat exchanger, a blocked vent or a faulty safety control can allow carbon monoxide into your home or cause the furnace to overheat. Keep working carbon monoxide detectors near bedrooms and on every level. If a detector sounds or anyone feels dizzy or nauseous, get everyone outside, then have Plumbing Masters inspect the furnace before using it again.
