Why a Heating System Can’t Keep Up with Cold Temperatures

Thermostat problems are the most common reason a home heater doesn’t provide enough warmth.

When winter winds and freezing temperatures cause a house to become cold, most homeowners go straight to the thermostat and turn up the heat. The heating system regularly forces air throughout each room to keep the home warm and comfortable.

However, sometimes, the furnace may work just as hard, but the house stays cold. Keeping the home warm can be a demanding task during freezing weather. During cold weather, it’s essential that homeowners can rely on their heating systems. There are several reasons why a system may not be performing to expectations.

Thermostat problems

Thermostat problems are the most common reason a home heater doesn’t provide enough warmth. The system can be tested when the temperatures outside are hovering around freezing. The thermostat is likely faulty if the heat is turned up, but the home remains cold.

An older mechanical thermostat may need to be recalibrated or leveled. Some thermostats may have wiring issues. With any thermostat repair, it’s best to call in a professional. Wiring and heating systems can be tricky, and an incorrect fix could put people in the home at risk. Check with an HVAC company to ensure the job is done correctly.

Coiler malfunction

Some systems utilize coilers to provide heat, such as boilers and steam heating systems. If heat is only released about half the time the furnace is on or no heat is produced, the coiler is likely malfunctioning. It’s not unusual for coilers to wear out over time and must be replaced. Don’t attempt this as a DIY project—repairing heating coilers is a technical job that requires professional care. Boiler systems aren’t complicated, but one small mistake could cost thousands of dollars.

Blocked ducts

Blocked ducts are another issue that can impair a heating system’s production. Over the years, heating ducts can become clogged with dirt and debris from the system and prevent the free flow of warm air throughout the home. Regular yearly maintenance can prevent clogged ducts, but if the system hasn’t been maintained professionally, it’s easy for the ducts to become blocked.

If the heat is on, but there’s a lack of airflow from one or a few ducts, perform a visual check to ensure nothing apparent has been blocking the duct. If there isn’t a visible blockage at the vent, call a professional to inspect the ducts. This is a simple procedure and one which, when done professionally, improves the system’s efficiency.

Many homeowners put off calling a professional when their heating system falters because they don’t want to face an expensive repair or replacement. However, the longer these issues are put off, the worse and more expensive they can become. Additionally, warmth in the home during winter is crucial, as all family members deserve to live comfortably. Contact a professional as soon as these issues arise for expert repairs to return the heating system to working order quickly.
