It's the middle of winter, the temperature outside has dropped, the weather is dreary...and your furnace is blowing cold air into your already chilly home. It's a frustrating scenario that many homeowners find themselves in with no explanation as to why it's happening. Fortunately, a furnace that emits cool air doesn't always mean major malfunctions and expensive repairs.

Many times, your local heating professional can resolve this issue with a quick fix and get your furnacing working properly again. However, you should never ignore these types of issues with your furnace as it could be a cry for maintenance. Read on to see four common reasons why your furnace is failing to produce heat in your home and how your HVAC experts can help!

Clogged Filter

Over time, your furnace filter can become bogged down under dirt and debris. When this happens, your furnace is unable to effectively distribute heat throughout your home and will have to overwork itself to meet the desired temperature. In doing so, it can easily overheat and stop producing warm air. In this case, the clogged filter is to blame for your furnace blowing cold air into your home.

Many times, a dirty furnace filter is the culprit behind such malfunctions, but the good news is that it's an easy fix for a qualified service technician. If you suspect that a clogged furnace filter is the source of your heating woes, then contact your local HVAC professional and schedule a heating tune-up service.

Thermostat Issues

If you already have your thermostat set to HEAT and the fan set to AUTO (the correct settings that tell your furnace to generate heat), and you're still experiencing cold airflow from your furnace, then there could be problems with the thermostat itself. A miscalibrated or otherwise faulty thermostat could be failing to communicate with your furnace. An HVAC pro can quickly determine if the thermostat is the problem and needs fixing.

Leaking Air Ducts

If your furnace can't supply warm air, then damaged air ducts could be to blame. It's possible that hot air could be escaping through holes and tears in your ductwork and leaving you to shiver in a drafty house. If you've ruled out other causes for your furnace malfunction, then you should consider having a technician inspect your ducts for air leaks.

Short Cycling

Short cycling refers to when your furnace cuts off before it completes a proper heating cycle only to rapidly start up again and repeat the process. This frequent cycling puts extra strain on your furnace and may cause it to overheat. The cold airflow is your furnace's way of cooling itself back down after overheating. In this situation, it's best to call in a service technician to investigate the cause of short cycling so that this problem doesn't persist and cause damage to your furnace.
