The first cold night of the year made your furnace quit work that night. You are forced to wake up in your home icebox and wear heavy coats and gloves indoors. You need urgent furnace repair.
The furnace works when its many moving parts work together. These devices are highly designed machines with motors, fans, flame rectification systems, sensors, igniters, gas valves, controls, and bearings. Failure of only one of these components can fail the entire system or failure of other parts. Common furnace problems are:
A burner that does not stay on
Fans that never turn off
Lack of airflow from the fan
Problems with turning on the light
Trust our skilled furnace technicians
You need a reliable team when scheduling oven repairs. Keeping your home warm and comfortable is important to you and your family, which is why you should rely on a team of highly trained technicians at Infinity Air.
Air filter clogging: If the thermostat is not set to “on” and the fan motor is always running, the air filter clogging is the leading cause of the fan motor running all the time. If the airflow is restricted, the limit switch that senses the heater’s internal temperature may be damaged. Infinity Air technicians don’t just replace switches. First, they identify the problem. If the cause is a clogged filter, a technician will explain how to replace the air filter.
Motor capacitor problems: These problems prevent the fan from turning on after the burner is ignited. Capacitors are easy to replace, but motor problems may require a little more troubleshooting.
Motor failed to start: You may hear a squeak from the failed motor. A technician needs to take immediate action to prevent the furnace from breaking down.
No Ignition: In a spark ignition furnaces, a fast scale indicates that the burner is about to ignite. If it does not light up, the chimney may be clogged, the control panel may be defective, or the limit control may be inappropriate. Repairing or replacing these parts should resolve the issue.
No Power in Furnace: If the fan does not respond to the thermostat’s temperature rise, the breaker may be activated, the wiring may be loose, or the oven breaker may be off. More complex issues include transformers, thermostats, control boards, running capacitors, or fan motors. Technicians can run diagnostic tests to identify the exact problem and find a solution.
The burner problem: If the burner does not light, the most common cause is a dirty flame sensor or, in a condensing furnace, and clogged condensate outlet. If the burner does not ignite at all, the gas supply may be cut off. To fix this, our technicians only need to clean the key components and make a few changes.
Also, call us if the heater turns on and off frequently, if the fan is running continuously, or if the unit makes a loud rattling or squeaking. There may be a severe mechanical problem, or the burner may be clogged. Needs to be fixed immediately. Furnace repairs are not always sufficient. It is recommended to install new furnace in the following cases:
Often needs repair.
Repair costs are very high.
The unit is over 15 years old.
Our technicians will suggest more efficient replacements.
