When winter hits Reno and Sparks, your HVAC system becomes one of your home’s most valuable assets. But if your home still feels cold—or your energy bills are rising—it could be time to act. Before you panic or assume a major breakdown, consider if it might be your HVAC system struggling in Reno’s cold. Check a few common culprits. Your HVAC system might just need a little care to get back on track.

1. Start with the Thermostat
It may seem obvious, but check your thermostat first. Sometimes it’s accidentally set to “cool” or the batteries have died. Ensure it’s in “heat” mode and the fan is set to “auto.” Also, try raising the temperature a few degrees to see if the system kicks on. This might help if your HVAC system is struggling in Reno’s winter weather.
2. Inspect the Air Filters
Clogged filters are a top reason HVAC systems struggle in winter. They block airflow, making your system work harder than it should. If you haven’t changed your filter in the last month, it’s time. Dirty filters also worsen indoor air quality—a big concern in closed-up winter homes and can indicate an HVAC system struggling in Reno.
3. Listen for Unusual Noises
If your system sounds louder than usual, something could be off. Rattling, grinding, or banging sounds often signal loose or broken parts. It’s best to call a technician before minor issues turn into big repairs when your HVAC system is struggling in Reno.
4. Check Air Vents and Registers
Blocked or closed vents can cause uneven heating in your home. Walk room to room and ensure all vents are open and unobstructed. Furniture, rugs, or curtains can block airflow without you realizing it.
5. Review Energy Bills and Heating Performance
Has your heating bill jumped compared to last year? That’s often a clue your system is losing efficiency. Older units can struggle to maintain temperatures, especially during freezing Reno nights. Over time, components wear out, making your system work harder for the same result, which may be a sign of an HVAC system struggling in Reno.
6. Look for Cold or Drafty Rooms
Uneven temperatures may point to ductwork issues or poor system balance. This is especially common in two-story homes or rooms above garages. Proper duct sealing and system calibration can often solve this.
7. Schedule a Professional Tune-Up
Routine maintenance is key to keeping your HVAC system efficient. A professional technician can check all components, clean internal parts, and catch issues early. Don’t wait until the furnace fails on a freezing Sparks night.
