You’ve been trying to get your furnace working, but it’s still blowing out cold air. It might seem like a simple fix, but there are actually several common reasons why a furnace would start blowing out cool air instead of warm air. Here are some things that could cause this problem: HVAC Company Lindstrom MN
If your heating system is blowing out cold air, the most likely cause is that the thermostat is set on “cool.” In order for your furnace to turn on, it must be set to heat and there should be no other conditions preventing it from turning on (such as a dirty cooling coil). If the thermostat has been accidentally bumped or moved from its original setting, this can easily cause the heating system not to operate properly.
To check this first, make sure that your thermostat has been reset properly (for example: if you have a separate room temperature controller or fan controller, make sure those are also set correctly). Then check your furnace inspection tag located near where your furnace was installed in order to verify what type of system you have – this will tell if you need a gas or electric unit as well as whether they have dual fuel capability or not. If none of these steps work then call an HVAC technician because something else may need repaired!
If you’re seeing emergency heat come on when it’s not freezing outside, here are some things to check:
If your furnace is blowing out cold air, it could be that the circuit breaker or fuse that turns on the power to your furnace has been tripped.
Circuit breakers are used to prevent damage to electrical equipment and overheating by cutting off power when a circuit overloads. They can also be reset quickly once they’ve been tripped by flipping the switch back up and down again until you feel it click into place. Fuses are designed to fail safely, preventing fires from occurring in the event of too much current draw on an electrical line; when a fuse blows, you should replace it with one of similar capacity (the number listed on both sides). You can test a blown fuse by using another known good one as a replacement; if this works properly then there’s nothing wrong with your original one but rather something else has caused it to fail (such as an overload).
If you’re having trouble identifying which component is causing your problem or don’t feel comfortable replacing either part yourself then contact us today! We’ll send someone out right away who will fix this issue for you so you can get back inside where it’s warm and cozy while they work their magic!
How often you should replace your filter depends on the type of furnace you have, but it’s generally a good idea to check the filter every month. If your furnace is blowing out cold air, it may be because there’s a buildup of dust on your filter.
If this sounds like an issue you’re facing (or something that might happen in the future), don’t worry! There are some quick fixes for cleaning your filter: simply vacuum any loose debris from its surface and replace it where it belongs. If there’s still some gunk left behind after vacuuming, try using water to soften up stubborn spots before scrubbing with soap and water or rinsing with a garden hose until clean.
Your furnace may have a problem with the pilot light. The pilot light is a small flame that burns constantly to ignite the gas in your furnace. If it goes out, your heat won’t work right and you’ll get cold air blowing out of your vents.
Pilot lights can go out for many reasons, including dirty filters, dust and lint buildup around the burner area, or an electrical problem with your heating system (like loose wiring).
If the blower fan isn’t working, it could be due to one of the following:
If the heat exchanger is cracked or broken, it won’t work properly. The heat exchanger is a metal box that transfers heat from the flame to the air in your home. It’s important to have your heat exchanger checked regularly so you can prevent bigger problems down the road. For example, if a crack isn’t repaired and gets worse over time, it could cause carbon monoxide poisoning or make dangerous fumes into your home during winter months when you’re running your furnace constantly. If your heat exchanger is broken, you will want to contact a professional like True North Heating and Air. We are your local HVAC Company Lindstrom MN and can come assess your HVAC System to see what needs repaired so you can be warm this winter.
