Top Signs You May Need Furnace Repair

A flawlessly functional furnace is vital as you head into the heating season. To ensure you have one, you’ll need to pay attention to your unit’s subtle hints. Here are the signs you’ll need to call for the best furnace repair in St. Louis Park.


Strange Sounds or Odors

Most furnaces make some noise. Some might have a light smell when you turn them on for the first time of the season, too. But loud banging or persistent, strong smells aren’t good signs.


Pay close attention to plastic-like smells or anything that smells like natural gas; both indicate there’s something seriously wrong with your unit. Turn off your system and contact an HVAC repair professional immediately.


Loud noises can be equally concerning, so they are also an indicator to temporarily stop using your unit.


Constant Cycling

If your furnace is turning on and off constantly, this is known as short cycling. It’s a common inefficiency issue that can go sideways quickly. It puts extra stress on the components and is a sign that your system is struggling to keep up with the demand.


The best furnace repair in St. Louis Park could potentially fix this, but it could also be a sizing issue with your unit. Talk with your HVAC professional to learn which it is.


Increasingly High Energy Bills

Utility bills spiking without an increase in usage is a clear indicator that something’s wrong. Inefficient units work harder and longer to achieve the same temperature as efficient ones.


If your furnace feels like it's running constantly just to reach a baseline temperature, that’s a sign that it needs some professional attention. The root cause of the inefficiency could be just about anything, and a diagnostic visit can help determine the best course of action.
