10 Common HVAC Issues Each Winter

There’s nothing like using the fireplace during the Kansas City winter, turning on the twinkling lights, and brewing up some hot cocoa. No matter how badly you want to cozy up, the falling temperatures can cause problems for your HVAC system.

Here are some common issues your HVAC system might experience this snowy-filled season.  

  1. Dirty Filters

We know we talk about dirty filters a lot, but that’s because it’s so important! 

Though dirty filters aren’t unique to winter, it remains a common issue. Think about all that nasty gunk that gets trapped in your filter! If you don’t keep the filter clean, it could restrict airflow and cause strain on your furnace. As a good rule-of-thumb, change your air filter every few months.

  1. Dirty Condenser or Evaporator Coils

With winter comes debris that can harm your condenser. Too much debris could clog the coils and cause the compressor to overheat.

  1. Pilot Light or Ignition Issues

For HVAC systems that run on gas or propane, the pilot light needs to ignite correctly. If it doesn’t ignite, then that means there is likely an issue with the flame sensor.

  1. Carbon Monoxide Leaks

Carbon monoxide leaks are dangerous because often, they go undetected. Cracks that develop in the heat exchanger increase the threat of this harmful chemical leaking. We recommend installing detectors and making sure to get regular inspections to prevent this issue.

  1. Uneven Heating

Your furnace should heat all rooms evenly, but if one feels like the North Pole and the other feels like the Sahara Desert, there could be some issues with heating. 

The problem could point to poor insulation like the weatherstripping or gaps in the house. You might want to check vents to ensure there aren’t any toys or furniture set right over it. And if that’s not the case, then the ducts, filters, or coils might need a clean!

  1. Cycling Heat

Is the heat clicking on and off constantly? That could mean a faulty thermostat or a clogged filter.

When it cycles like this, it can cause wear and tear–and a higher energy bill! 

  1. Frozen Pipes 

Many homeowners like to cut costs during the winter by turning off the furnace completely when away. Be aware! The heating system can freeze if you don’t keep it running, resulting in frozen (and possibly bursting) pipes! 

Ensure no ice accumulates on the outdoor HVAC pump and coils to avoid frozen pipes as well!

  1. Blown Fuses or Tripped Breakers

The most common cause for blown fuses and tripped breakers is a dirty air filter, causing the furnace to overwork. 

If it’s not the filter, you’ve likely got an overloaded circuit between the oven, TV, lights, or some wiring connections issues. It’s not a bad idea to get your HVAC unit checked either! Blown fuses and tripped breakers can be a sign of a poor unit altogether.

  1. Burning Smell 

While it’s normal for furnaces to give off a burning smell the first time you turn your furnace on this winter, it shouldn’t continue all season long. That could indicate wiring issues, dirty filters, or overheated motors.If you need any help prepping your furnace for the winter or would like an inspection with one of Blue HVAC’s trusted technicians, you can schedule an appointment today or call us at 816.719.1099.
