When to Call for a Gas Furnace Repair in Trumbull, CT, If It’s Blowing Cold Air?
A gas furnace helps warm your home during cold weather. However, what happens if it starts blowing cold air? This troublesome situation can leave you chilled, wondering if you need gas furnace repair in Trumbull, CT. If you understand some possible causes and when to call in an expert, you can resolve the issue quickly.
Reasons Why Your Gas Furnace May Not Be Heating the Home
Several problems may prevent a gas furnace from generating any heat. Some of the most common reasons are:
1. Pilot Light or Ignition Problems
Check your pilot light if your furnace has one, and see if it is lit. If it is not lit, a faulty thermocouple or a gas supply problem may be preventing ignition. A modern furnace may have an electronic ignition with a malfunctioning sensor or circuit board requiring specialized repair.
2. Clogged Air Filter
A dirty air filter can restrict airflow and cause the furnace to overheat, triggering a safety shutoff. To correct this, clean or replace your filter regularly.
3. Faulty Gas Supply
A furnace cannot provide heat if it fails to receive enough gas. A low gas pressure and a closed gas valve together will lead to the blowing of cold air through your vents.
4. Ductwork Leaks
Leaky ducts can make your furnace appear to blow only cold air as the heat escapes before reaching the living space. Sealing duct leaks and ensuring air escapes properly can enhance heating efficiency.

Frequently Asked Questions (FAQs)
1. Why does my gas furnace blow cold air only sometimes?
Your gas furnace may blow cold air due to overheating, a malfunctioning thermostat, or a gas valve issue, causing it to switch from warm to cold air. An expert can diagnose and fix the problem.
2. Can a dirty air filter cause the furnace to blow cold air?
Yes! The excess dirt in a filter can restrict airflow, causing the furnace to overheat, which shuts off the burner while the fan continues blowing cold air.
3. How do I reset my gas furnace if it’s not heating?
Turn off the thermostat for about 5 minutes, then set it appropriately again. If the problem persists, call for gas heater repair near me.
