Surviving the Cold: 9 Common Winter HVAC Woes and How to Fix Them

Feb 29, 2024

Brrr… It’s Cold in Here

As winter tightens its grip, so does the reliance on our trusty HVAC systems to keep us warm and cozy. But like any machine, HVAC systems aren’t immune to problems, especially during the coldest months. Various issues can leave you shivering instead of snoozing, from malfunctioning thermostats to frozen coils.

9 Most Common HVAC Problems During Winter

1. Uneven Heating

This can occur due to clogged air filters, blocked vents, or malfunctioning dampers. It can also signify an undersized system struggling to keep up with the demand.

2. Short Cycling

Your furnace keeps turning on and off rapidly, never reaching optimal temperature. This can be caused by a dirty furnace, faulty thermostat, or even low refrigerant levels (in heat pumps).

3. Pilot Light Issues

Flickering or extinguishing pilot lights in gas furnaces can be caused by drafts, dust, or a damaged flame sensor.

4. Strange Noises

Banging, grinding, or screeching sounds could indicate loose parts, failing bearings, or a clogged blower fan. These issues require immediate attention to prevent severe damage.

5. Frozen Coils

When warm, humid air hits the cold evaporator coil, it condenses into water. If the temperature dips too low, this water can freeze, blocking airflow and compromising efficiency.

6. Lack of Heat

This could be due to a complete system failure, a tripped breaker, or a thermostat malfunction.

7. Poor Indoor Air Quality

Dry, dusty air during winter can exacerbate allergies and respiratory problems. Regular filter changes and humidifier use can help combat this.

8. Ice Buildup

Excessive ice buildup on the outdoor unit of your heat pump can restrict airflow and lead to system failure.

9. High Energy Bills

A poorly maintained or inefficient HVAC system will work harder to maintain your desired temperature, leading to increased energy consumption and higher utility costs.

How to Prevent Winter HVAC Issues: 5 Important Tips

1. Schedule Regular Maintenance

Preventative maintenance is key to catching minor issues before they become significant problems. Aim for a professional inspection and tune-up at least once a year, preferably before the winter season.

2. Change Air Filters Regularly

Dirty air filters restrict airflow and reduce system efficiency. Replace your filter according to the manufacturer’s recommendations, typically once a month.

3. Clean Vents and Registers

Blocked vents prevent proper air circulation and can lead to uneven heating. Regularly remove dust and debris from vents and registers to ensure optimal airflow.

4. Weatherproof Your Home

Seal air leaks around windows, doors, and other openings to prevent drafts that can strain your HVAC system.

5. Upgrade Your Thermostat

Consider a programmable thermostat that allows you to adjust temperature settings based on your schedule and preferences. This can help save energy and improve comfort.
