Lennox Furnace Repair FAQ
How do I know if my HVAC system needs service?
Signs your HVAC needs service include: unusual noises, weak airflow, inconsistent temperatures, higher than normal energy bills, frequent cycling, strange odors, and visible leaks or moisture. If your system is over 10 years old and hasn't been serviced recently, schedule a tune-up.
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.
