Frequently Asked Questions

Why is my furnace blowing cold air?
Causes include: thermostat set incorrectly, pilot light out, flame sensor dirty, gas supply issues, overheating from dirty filter, or ductwork problems. Check thermostat settings and filter first. If the pilot light is out or you smell gas, call a professional immediately.
How often should my furnace cycle?
A properly functioning furnace typically cycles 3-8 times per hour, running 10-15 minutes per cycle. Frequent short cycles (under 5 minutes) indicate problems like oversizing, dirty filters, or thermostat issues. Cycles longer than 20 minutes may indicate undersizing or heat loss.
Should I repair or replace my old furnace?
Consider replacement if your furnace is over 15-20 years old, repairs exceed 50% of replacement cost, it has a cracked heat exchanger, or energy bills are climbing despite maintenance. New high-efficiency furnaces can reduce heating costs by 15-30%.
Why does my heater smell like burning?
A burning smell when you first turn on heat is often just dust burning off after months of disuse—it should clear within an hour. Persistent burning smells may indicate electrical problems, overheating, or debris near the heat exchanger. Turn off the system and call for service if smells persist.
