Comprehensive Solutions for Any Furnace Problem

A furnace is a complex system with many interconnected components, and a problem with one part can affect the entire unit. Our experienced technicians have seen it all and are trained to accurately identify the root cause of any issue. We provide lasting repairs for a wide range of common and uncommon furnace problems, including:

Furnace Fails to Turn On

One of the most common issues is a furnace that won’t start at all. This can be caused by several factors, ranging from simple thermostat issues or a tripped circuit breaker to more complex problems like a faulty ignition system, a malfunctioning control board, or an issue with the gas supply. Our experts will perform a systematic diagnostic check to pinpoint the exact reason and implement the correct fix.

Insufficient Heat or Blowing Cold Air

If your furnace is running but not producing enough heat—or worse, blowing cold air—it’s a clear sign of a problem. This is often linked to a clogged filter restricting airflow, but it can also indicate a malfunctioning gas valve, a problem with the burner, or leaky ductwork that is losing heated air before it reaches your rooms. We will thoroughly inspect your entire system to restore proper heat output.

Strange Noises During Operation

Your furnace should operate with a relatively low hum. Loud or unusual noises like banging, screeching, rattling, or groaning are indicators of mechanical trouble. A banging sound could point to delayed ignition, while high-pitched squealing often suggests a problem with the blower motor belt or bearings. Rattling may indicate loose panels or debris. Ignoring these sounds can lead to more severe damage, so it’s crucial to have them inspected immediately.

Pilot Light or Ignition System Failures

Modern furnaces use electronic ignition systems, while older models may have a standing pilot light. If your pilot light is out and won't relight, or if the electronic ignitor is failing, your furnace will not produce heat. These issues can stem from a faulty thermocouple, a dirty pilot orifice, or a cracked ignitor. Our technicians are skilled in repairing and replacing all types of ignition components safely and effectively.

Constant or Frequent Cycling

Does your furnace turn on and off more frequently than usual? This "short cycling" is not only inefficient and drives up your energy bills, but it also puts excessive wear and tear on the system. The cause could be an obstructed filter, an improperly sized unit, or a malfunctioning thermostat. We will identify the reason for the frequent cycling and provide a solution to ensure your furnace runs in smooth, efficient heating cycles.
