What are some common problems that heating systems can have during cold weather, the causes for these problems, and how they can be resolved?

As the cold weather sets in, the last thing any homeowner wants is a heating system that fails to keep the home warm and comfortable. It's not just a matter of discomfort; inadequate heating can lead to further problems like frozen pipes and increased wear on the heating system. But why do these issues arise, especially when needed most? And more importantly, how can a heating contractor help in resolving these challenges? This blog explores some common reasons behind underperforming heating systems during cold weather and the role of a heating contractor in troubleshooting and fixing these issues.

The thermostat controls the whole heating system like a command center. If it's not working properly, the furnace can't maintain your desired temperature. Some thermostat issues include:

Incorrect temperature reading due to poor location or calibration. Dirt buildup on sensors preventing accurate readings. Worn components causing failure to properly signal furnace. Loose wiring connections intermittently breaking the signal. Dead batteries disabling the thermostat.

Heating pros have specialized tools to test thermostats and pinpoint issues. They can repair, adjust, or replace your thermostat to restore normal function.

Forced air furnaces require adequate airflow to deliver heated air throughout your home via ductwork. Restricted airflow causes uneven heating as some rooms receive too little warm air. Here are some common culprits:

Dirty air filters blocking airflow. Blocked vents due to furniture placement or closed doors. Crimped flexible ducts reducing flow. Closed dampers to unused rooms limiting air circulation. Faulty blower motor unable to push enough air.

Technicians can measure your system's airflow volume and pressure to identify and remove restrictions. They also test blower motor operation and make duct modifications if needed.

When an undersized furnace can't produce enough heat to warm your home sufficiently during extreme cold, the culprit is often an improper heating load calculation made during original furnace installation. Your home's needs likely changed over time:

Remodels, additions, and larger occupants increase the heating load. Insulation upgrades reduce the calculated load but are unaccounted for. New windows, doors, sidings affect heat loss not reflected in old load data.

Heating pros can analyze your home's heat loss using approved methods and determine if your furnace capacity matches the updated requirements. An oversized furnace is less efficient while an undersized one can't keep up. Right-sizing your furnace prevents this issue.

The constant cycling of heating equipment leads to wear and tear on components. When parts degrade too far, the system can no longer operate properly. Some examples include:

Ignitors and flame sensors misfiring the burner. Valves sticking or leaking and preventing combustion. Blower and fan motors seizing up. Tripped safety switches unable to reset. Corroded heat exchangers leaking exhaust gases.

Skilled technicians have the experience to isolate problems in complex furnace components. They can test operation, replace damaged parts, and ensure everything functions safely and efficiently again.

Lack of periodic furnace maintenance often results in preventable failures. Routine inspections and cleaning by technicians can uncover issues before they escalate into major breakdowns. They also optimize settings and adjust components like valves and burners for peak efficiency - something DIYers can't replicate. Don't skip your annual tune-up!

The Solution: Hire a Professional Heating Contractor

While one can try some basic home remedies to get heat flowing again, systemic or complex problems require a professional's expertise. Heating contractors have the diagnostic tools, repair skills, and experience needed to get your furnace firing properly day and night. Don't leave your family shivering; call a reputable heating company for prompt, quality service you can rely on all winter long. With the right attention from a knowledgeable pro, your home will be warm and cozy again in no time. Stay warm out there!
