As the weather cools and your house heats up, stay safe by monitoring your furnace. Neglecting your furnace doesn’t just lead to heating issues and high energy bills. It can cause deadly carbon monoxide poisoning and fires. Stay safe and avoid disaster this winter by checking your furnace using our tips and tricks!

Strange Noises

A light hum from your furnace is not an issue. If you hear a banging noise, whistles, or groaning coming from your furnace, call an expert. Not only are these sounds annoying, but they indicate something is wrong with your furnace.

Pilot Light Color

Check the pilot light on the furnace. A blue light indicates the furnace is working. If the pilot light is yellow, call your gas service provider immediately. A yellow light indicates high levels of dangerous carbon monoxide are present and the gas is not dispersing correctly.

Bad Odors

When you first turn on your furnace, the initial smell of burning dust isn’t a cause for alarm. Issues arise when the bad smells persist for more than a couple of days. If you smell gas or oil, contact an expert right away, turn off all appliances to reduce the risk of fire, and leave the area. The smell of gas is a sign that there is a dangerous gas leak happening. If the bad odor is unrelated to gas, give us a call and we can help.

High Electricity Bills

High electricity bills can indicate that your furnace is not working properly. This is not only a bad sign for your wallet, but it can indicate safety issues. If you notice your bill is much higher than usual, call your local HVAC repair team. They will diagnose and fix the issue, which will save you money in the long run, and keep you safe from possible carbon monoxide leaks.

Inconsistent Heating

When rooms are vastly different temperatures, that is an indication something is wrong with your furnace. Your furnace is supposed to heat your house evenly. Get your money’s worth out of your furnace and stay safe this winter by having an HVAC repairman check out your furnace.

Changes in Air Quality

A clean furnace filter is essential to the air quality in your home. A dirty furnace filter is not only a fire risk, but it can spread pollen, dust, and mold throughout your home. Bad air quality will exacerbate problems for people with asthma and other respiratory issues. Make sure you clean your furnace filter before you turn it on for the first time this season to prevent these issues.

Excess moisture

Condensation and damp air throughout your house can be a sign that your furnace isn’t creating sufficient airflow. Not only does the damp air feel uncomfortable, but it can also cause mold to grow. Mold growth is difficult to get rid of and can cause health problems if left untreated. If you have issues with mold, check out our mold removal services.
