It\u2019s time to re-explore an issue that we get called about a lot during this time of the year\u2014a furnace that\u2019s blowing cold air. This is of course a very unsettling problem and not one that you want to face. When your furnace suddenly starts blowing out cold or lukewarm air from the vents, it\u2019s easy to panic. But before you do, check out our advice below. <\/p>\n\n\n\n

The thing is, there are a number of reasons that a furnace may experience this problem. Some of them amount to nothing more than \u201cuser error\u201d while others are of course more serious and will require a professional to fix. Read on to determine which is the case for you. <\/p>\n\n\n\n\n\n\n\n

Thermostat Trouble<\/h2>\n\n\n\n

Sometimes a problem with a furnace isn’t a problem with a furnace at all. What we mean, is that the problem might be coming from the thermostat. Yes, it could be malfunctioning and reading indoor temperatures incorrectly or not properly regulating the temperatures, but another possibility is that user error we mentioned above. <\/p>\n\n\n\n

There\u2019s no reason to be embarrassed (you don\u2019t even have to\nadmit to us that this is what happened) but what we\u2019ve found in a few cases is\nthat homeowners have their thermostat set to \u201con\u201d instead of \u201cauto,\u201d and when\nthey feel cold or lukewarm air, it\u2019s because the fan is on, but the furnace isn\u2019t\ngenerating heat because the indoor temperature is already <\/em>what you have set on the thermostat. <\/p>\n\n\n\n

Check to see if this is the case. If it\u2019s not, read on! <\/p>\n\n\n\n

A Dirty\/Clogged Air Filter<\/h2>\n\n\n\n

When the furnace air filter gets too clogged up, it can\nstart causing problems. What happens is that it restricts airflow into <\/em>the furnace, which causes the\nsystem to overheat. When this occurs, the system will shut down as a safety\nmeasure. The fan, however, will keep blowing air to cool down the heat\nexchanger, so as a result you might feel cool air coming through the vents. <\/p>\n\n\n\n

You can prevent this from happening by changing your air filter out every 1\u20133 months, depending on the type of filter. Please don\u2019t hesitate to ask our professionals for guidance if you\u2019re unsure how often you should be changing yours. <\/p>\n\n\n\n

Broken Heating Elements<\/h2>\n\n\n\n

So let\u2019s say the neither the thermostat or the air filter are to blame. If you have a gas-powered furnace, this doesn\u2019t apply to you, as combustion gas heats up these types of systems. But an electric furnace can suffer from broken heating elements. Our professionals can closely inspect each element to pinpoint the exact source of the problem and repair it accordingly. You want any broken heating elements repaired right away to restore functionality.<\/p>\n\n\n\n

Damaged Ductwork<\/h2>\n\n\n\n

When there\u2019s a breach in your air ducts, warmed air can leak\nfrom the ventilation system. In addition, a breach will cause air from other\nparts of the home, most of it colder than the air from the furnace, to enter\nyour furnace. This will cause a drop in temperature. Fortunately, our team is\nhere to help. <\/p>\n\n\n\n
