Furnace Always Running? Get Furnace Repair in River Hills
4.9 Google Rated
A constantly running furnace is both a nuisance and a serious concern. At best, you may wonder how much money you’re wasting when your next utility bill rolls around. At worst, you could end up with an overworked furnace that shuts down later.
If you’re wondering whether you need furnace repair in River Hills, WI, let’s first explore the reasons behind this common issue. Sometimes this issue can be fixed with a little home maintenance, while other causes require a professional.
3 Simple Reasons Behind Your Furnace Running Constantly in River Hills
Is your furnace damaged or just a little dirty? Start your process of elimination with the simplest reasons behind your heating unit’s odd behavior.
1. Extremely Dirty Filter
Your furnace might be constantly running because a very dirty filter is affecting its airflow. Without good airflow, your equipment struggles to raise the room’s temperature. Since its thermostat is still telling the unit the room is too cold, it stays on.
You should swap out your dirty filters for a clean one every few months. Active households with children or pets should do so every three months, while singles and couples will likely do fine every four to five months.
2. Incorrect Thermostat Settings
Alongside dirty filters, sometimes your thermostat isn’t working quite right, telling your furnace it’s cold when it’s actually warm or vice versa. If it’s sending cooler readings, your equipment will stay on until that reading changes.
Check your thermostat to make sure it’s set to the appropriate temperature (we recommend between 68 to 75 degrees Fahrenheit). If it is, try lowering or raising the temperature a few degrees to see if a different setting stops your furnace from running.
No dice? Try the third item on this list; if not, you’ll need a professional to see why your furnace runs constantly in River Hills.
3. Wrong Setting
This suggestion may seem obvious, but overlooking the setting is one of the most common reasons behind a constantly running furnace! Make sure your furnace is set to the heating function, then try the ‘On’ setting instead of ‘Auto’.
The ‘On’ setting makes your furnace’s fan continuously run, while the ‘Auto’ setting makes your furnace run only when it’s heating.
Short-cycling furnaces are also a frustrating occurrence. If your equipment runs too long or not long enough, you may have some deeper problems that need addressing.
3 Serious Reasons Behind a Constantly Running Furnace
If you have the right settings and clean filters, your furnace is trying to tell you something else is at play. Let’s take a look and see why your equipment keeps running without explanation.
1. Malfunctioning Blower Fan
Your blower fan is responsible for sending warm air throughout the house. If it’s damaged or failing, it might ‘confuse’ your furnace into thinking the room is colder than it actually is.
You can’t fix a malfunctioning blower fan on your own. An experienced heating technician needs to safely inspect your furnace and see if you need a repair or a replacement.
2. Improper Sizing
A furnace that isn’t properly sized for your home will often swing to one of two extremes: short cycling or running constantly. These extremes point to how it’s either heating too fast or not fast enough.
If you’ve had your furnace for years and suspect it’s too small, we can help you with a new furnace installation. We combine in-person inspections with industry-standard manual load calculations to find the best size for your home.
3. Faulty Limit Switch
Your limit switch is a safeguard to protect your furnace from overheating. This switch connects to your thermostat to make sure your heating unit knows when to stay on and when to turn off.
If this limit switch is malfunctioning or broken, it won’t send the right signals at the right time, hence the constantly running issue you’re experiencing.
