Why Your Gas Furnace May Need Repair

Even in milder climates, gas furnaces can wear down over time, especially during cooler months when they’re used the most. Common repair issues include:
Dirty burners or blocked heat exchangers
Faulty ignition systems or pilot lights
Clogged air filters restricting airflow
Malfunctioning thermostats or control boards
Whether you’re in a colder northern climate or a warmer southern one, routine maintenance helps prevent sudden breakdowns and keeps your heating system working efficiently year-round.
