Do you feel like you’re in a house that’s not quite warm enough? Does it seem as though the furnace is taking a really long time to heat up your home? These are symptoms of having a problem with your heating system. What could be causing it? There are several possible causes: HVAC Company Scandia MN

Thermostat is Set to Fan Only

If you are using a two-stage furnace, and the thermostat is set to fan only, the furnace will not be able to produce any heat. Similarly, if your system is single stage and your thermostat is set to fan only, the heating system won’t work at all. To get hot air out of your vents again:

  • Make sure that the temperature setting of your thermostat is set to “heat.” If it isn’t already on this setting (or if you don’t know what setting it was on), look through its options until you find one labeled “Heat.”
  • Look at the manual for instructions on how to operate your particular furnace or air conditioner so that you can learn whether yours has a two-stage or single stage operation; then follow those instructions appropriately for changing settings based on whether or not they are currently being used.

Broken Furnace Motor

If the blower isn’t working, the motor may be broken. In some cases, you can replace it yourself. However, if you’re not comfortable doing this or if you have other furnace problems at the same time (such as a bad thermostat), it’s best to call a professional for help with your furnace repair. True North Heating and Air is your local HVAC Company Scandia MN that can help with your furnace repair so contact us.

Thermostat Set Too Low or Too High

  • Check the thermostat. If you have a digital thermostat, it’s likely that it will have a display screen with numbers or letters on it. The number or letter displayed should match with what temperature you set your home to be at. You can also look at the manual for your furnace and see if they list any recommended temperatures.
  • Check that there is power to your heating system and make sure all wires are connected properly – especially if you’ve recently moved into a new home or had somebody else work on your furnace in the past few weeks.
  • Make sure there isn’t any ice buildup on the pipes leading from outside into your house (this could potentially block airflow).

If none of this works, contact an HVAC professional for help at an HVAC Company Scandia MN!

Dirty Filters or Ductwork

  • Your furnace filters should be cleaned every 3 months. If you have allergies, consider cleaning them more often—perhaps every 2 weeks.
  • Ducts should be cleaned once a year, usually in the spring or summer before heating season begins.

Faulty Ignition Switch HVAC Company Scandia MN

  • How to test the ignition switch:
  • Check that there is power going to the furnace. You can do this by checking for power at the control board or disconnecting one wire at a time until you find one that doesn’t have power when you flip on a breaker or push in an interlock switch (if your system has one). If there is no power, check that your meter is working correctly and replace any blown fuses.
  • Do not attempt to operate your system without electricity! Doing so will damage it beyond repair. If the system won’t start with electricity, call a professional to fix it before attempting any repairs yourself.

Loose or Faulty Wiring HVAC Company Scandia MN

If your wiring is faulty, it can create a number of problems. First and foremost, the wiring might be causing a fire. In some cases, this fire could be caused by loose or faulty wiring in the furnace itself—but it could also be caused by faulty wiring elsewhere in your home’s electrical system.

When checking for loose or faulty wiring around your furnace, start by checking for signs of melting or burning around the wires themselves. If you notice any melting or burning on any part of the furnace (including parts inside its casing), turn off power from an outside source to eliminate that possibility until you can have someone check it out further. The same goes if you see sparks coming from anywhere near where those wires connect with other components.

Next up: make sure all outlets are working properly! This means turning them off and then back on again after making sure nothing was plugged into them at first glance (like lamps). You should also test each outlet with a light bulb as well as plugging in different things like radios or microwaves just to make sure everything is functioning correctly before calling an electrician over

There are a number of reasons why your furnace or AC isn’t blowing out hot air

There are a number of reasons why your furnace isn’t blowing out hot air. Furnaces and ACs can break down at any time, so it’s important to know what to do if your heating system stops working. The most common reason for this is that the fan motor has gone bad and needs replacement, but there could be other culprits as well:

  • A circuit board may have failed
  • The heat exchanger may have cracked
  • The thermostat may be malfunctioning
