Keeping Your Home Cool during the Sweltering, Summer Months

My Furnace Cannot Keep Up With The Thermostat–What Could Be The Cause?

by Anthony Graves

The cold season is here, and everybody expects that when they turn on the heating system, they will have a warm and comfortable home. However, this is not always the case, especially if you haven't maintained your heating system for a long time. That said, it is common to forget the annual tune-ups because the rest of the year doesn't require you to heat your home. So, if you have noticed that your heater cannot keep up with the thermostat, it is time to troubleshoot and find out possible causes. Here are some areas you may want to look into.

You Have the Wrong Furnace Size

It is crucial to choose the right size of heating system for your home. Note that mistakes in the selection process could lead to a system that overworks to reach the temperature set on the thermostat. On the other hand, you may have a unit that produces more heat than needed. Note that you will have no harmony between the heating unit and the thermostat with a wrong-sized unit. If this is the case, only an HVAC contractor can assess your heating needs and determine the ideal unit size. As such, the best remedy for this problem is getting the right furnace size according to your heating load.

The Problem is the Thermostat

The problem affecting the entire heating system could be the thermostat. You should know that this is the part of the unit that determines how hot or cold your home will be. Also, it fails more often than people realize. So, if you are not receiving the correct heating, it could be that you have set the temperature wrong, the batteries are too old, or your device is malfunctioning. Whatever the cause, you should have a professional assess it and see if it needs a new set of batteries, recalibration, or a replacement. More so, once the problem with the thermostat gets resolved, you will have harmony between it and the heater.

The System Might be Overheated

An overheating system is another cause of trouble when there is no harmony between the heater and the thermostat. In this case, overheating happens when you have restricted airflow into the heat exchanger or the result of short cycling. Either way, the cycles will be too brief for the heating cycle to reach the temperature set on the thermostat. The good news is that addressing the reason why the system is overheating will solve your problem.

These are the three most common reasons you will have a discrepancy between the temperature on the thermostat and the heater. Call a heating contractor close to you, and have them assess your system.
