Explore the reasons why and how Max Air Heating and Cooling technicians can help the customer resolve the problem.

There are many causes why your residential or commercial furnace could be blowing cold air. Furnace issues can be easily prevented by scheduling your regular yearly furnace maintenance. This is the best way to prevent unexpected furnace failures. The technicians at Max Air Heating & Cooling are experts in their trade and can keep your furnace working at full capacity when maintenance is done as recommended. Making sure your system is inspected and cleaned on a yearly basis is the best way to prevent failures including issues with blowing cold air instead of hot or furnace not turning on.

Thermostat issues could be a second common issue. Have you checked your thermostat batteries lately? If not, this could be the reason why your furnace is blowing cold air. Making sure that your thermostat settings are correct is also a very common problem that can be easily resolved. Did you recently install a new thermostat? Well, that can be a problem if the wrong thermostat was installed. There is a wide variety of thermostats on the market and most often than not the consumer does not know that a thermostat must be compatible with their installed furnace to work correctly. Calling a Max Air expert can help you avoid thermostat-related issues.

There are a few additional troubleshooting steps you can take to figure it out yourself such as checking the filter, resetting the furnace, and checking the pilot light. A dirty filter could be the culprit. Furnace filter changes are highly recommended and usually done by our technicians during a furnace tune-up, however, is something you can easily do yourself. Not changing your filters yearly or every three months in a commercial setting can lead to overheating the system and causing malfunction. A “blown out” pilot light is an easy fix. This can sometimes happen if air hits the flame on the furnace. If the flame successfully goes on but goes out again then there could be an issue with the sensor that controls ignition. The faulty part is called a thermocouple and can be replaced by one of our highly trained HVAC technicians. The furnace’s flame sensor could also be a cause for failure. The flame sensor must be free of debris and be in good condition to have a functioning furnace. A dirty or worn-out flame sensor allows for the burner in the furnace to continue to shut off.  Furthermore, there could be an electrical problem. This can be tested by resetting the system. If the furnace won’t turn on or fails to blow hot air after rebooting then it’s time to call a Max Air technician to assess and diagnose the problem.

Your furnace may also be blowing cold air instead of hot due to leaky air ducts. The ductwork that carries air or heat throughout your home or business can sometimes become leaky allowing hot air to escape. A heating and cooling expert can inspect your air ducts to make sure that this is not the problem. Many of the above-described issues can be DIY however, when in doubt or not comfortable doing it yourself Max Air Heating & Cooling is just a phone call away to help repair your furnace.
