Quick Answer
If your furnace in Colliers is blowing cold air, first check that it’s set to HEAT and the fan is on AUTO. Replace a clogged air filter and reset any tripped breakers. If it still won’t heat, a worn ignitor, dirty sensor, or duct leak could be the cause—best repaired by Honest Fix Heating, Cooling & Plumbing.
Colliers’ quiet hills and winding roads—stretching from Eldersville Road to Harmon Creek—create unique heating challenges. Many homes here rely on older propane or natural gas furnaces with long duct runs through unheated basements. When a furnace starts blowing cool air instead of heat, the cause could be simple—but in rural systems, it can also point to airflow loss or ignition failure that needs professional attention.
Simple Fixes Homeowners Can Try First
Make sure your thermostat is in HEAT mode and the fan set to AUTO, not ON. Replace filters every one to two months during winter to maintain airflow. Check for tripped breakers or a shutoff switch near the furnace. In Colliers homes with older electrical panels, this alone often restores power and proper operation.
When It’s More Than a Filter or Setting
If those steps don’t help, the problem may involve the ignition system or gas supply. Dirty flame sensors, cracked ignitors, or closed gas valves are frequent culprits. Homes along the wooded valleys near Harmon Creek often lose heat through unsealed ductwork or animal-damaged insulation. Honest Fix technicians inspect every component, from burners to airflow, to ensure a complete fix.

FAQs
Why does my Colliers furnace blow air but not heat?
It could be a failing ignitor or a sensor blocked by soot. If airflow is strong but cold, a technician can test ignition safely and quickly.
Do rural homes in Colliers lose more heat through ducts?
Yes. Long duct runs through crawlspaces or basements often lose heat before it reaches vents. Duct sealing helps maintain consistent warmth.
How much do furnace repairs cost in Colliers?
Most furnace repairs cost between $180 and $550. Ignitor or flame sensor replacement is common and covered by Honest Fix’s 5-year labor warranty.
