Furnace Maintenance


The impact of maintenance on your peace of mind and comfort.
Every situation is unique but, in our experience, furnace rental provides homeowners with peace of mind, predictability, and money savings, upfront and in the long run.
One of the most avoidable issues that keeps your furnace from performing at its full potential is having the fan setting set to “on” constantly. This results in the furnace blowing cold air since heaters are not designed to pump hot air continuously. Once they reach an optimum temperature, they take breaks until the temperature dips below the setting on the thermostat.
To make sure this doesn't happen, switch the fan setting to “auto” so the system will only blow hot air as needed.
Are you seeing fine dust floating around in the air? How often do you change your furnace filter? Filters should be changed as frequently as recommended by the manufacturer. This doesn't simply ensure optimal air filtration. A furnace blower has to work harder and more frequently to move air through a dirty or clogged filter, leading to much lower energy efficiency.
These clear tubes often show signs of debris stuck in the drain line. Don’t let a clogged condensate pump flood your basement. These can be cleaned at home with hot water and vinegar. If yours is continuously clogging, we’d be happy to install a new drain line for you at a nominal price.
A faulty gas valve can leak fuel into the surrounding air, causing a smell like rotten eggs when you take off the furnace door. If you notice a gas leak, do not operate any electrical switches. If you do, it may cause a spark and lead to a fire. It's important to simply get everyone out of the house immediately, then either call 911 or your local gas provider. They will give you further instructions on what you need to do.
Gas line issues can cause not only catastrophic problems, but also more common and simple ones. Some signs of gas leaks include a rotten egg smell, physical symptoms like fatigue or dizziness, dead or dying vegetation in your home, and groggy pets who are closest to the floor and therefore most affected by gas leaks. It's important to address gas line issues promptly to avoid further problems.
