Common Questions About Heating Repair
Find answers to common plumbing and HVAC questions from our expert team.
A furnace blowing cold air is typically caused by a faulty ignitor, a bad flame sensor, a tripped high-limit switch, or a thermostat issue. The high-limit switch is a safety device that shuts off the burner if the heat exchanger overheats, often due to restricted airflow from a dirty filter. We diagnose the root cause and fix it properly so you're not dealing with the same problem again next week.
