Common Furnace Problems We Fix
Furnace Not Heating
Thermostat set but house still cold? Furnace heating failures typically result from faulty ignition systems, dirty flame sensors, or malfunctioning gas valves. Our heating experts use advanced diagnostic tools to identify ignition problems, pilot light issues, and burner malfunctions for fast, effective repairs.
Furnace Won't Start
Furnace completely unresponsive despite thermostat settings? Furnace startup problems commonly stem from tripped circuit breakers, failed blower motors, or electrical component failures. Our technicians safely diagnose power issues, capacitor failures, and control board problems without risk of electrical hazards.
Furnace Blowing Cold Air
Heat running but only cold air coming from vents? This frustrating problem usually indicates ignition system failures, dirty flame sensors, or thermostat malfunctions. Our heating specialists quickly identify whether your system needs igniter replacement, sensor cleaning, or thermostat recalibration.
Noisy Furnace Operation
Banging, rattling, or grinding sounds from your heating system? Unusual furnace noises often signal loose components, blower motor problems, or delayed ignition issues. We pinpoint noise sources and perform precision repairs to restore quiet, efficient operation while preventing costly component damage.
Poor Heating Performance
Some rooms warm while others stay cold? Uneven heating typically results from clogged air filters, ductwork problems, or blower motor issues. Our technicians optimize airflow, clean or replace filters, and ensure proper heat distribution throughout your entire home.
