When You Know About Us, You'll Choose Us. Here's Why.

FACTORS THAT REDUCE FURNACE LIFE EXPECTANCY

As we’ve discussed, furnace life expectancy can vary quite a bit. Some of the factors that affect your furnace’s life are out of your control, such as sizing and installation of your furnace which are typically determined by your HVAC contractor. Other factors, such as maintenance and thermostat settings are in your hands. Let’s take a closer look:

FURNACE SIZE

It’s important to have an appropriately sized system for your home.

Shorter cycles create more wear and tear on the parts of a furnace, so if the system is larger than necessary, it will turn on and off too quickly.

Furnaces that are too small for the space may stay on too long and struggle to heat your home, which can also add wear and tear on parts.

POOR FURNACE INSTALLATION

Poor installation can affect the lifespan of your furnace for a number of reasons. This is why it’s so important to select a qualified HVAC professional, like your local Carrier expert, to install your system.

Poorly designed, sized, or sealed ductwork impacting airflow can affect your comfort and system efficiency

Poor drainage system for high efficiency furnaces

Incorrectly installed fuel lines

LACK OF ROUTINE MAINTENANCE

When you ignore recommended maintenance, dirty buildup on heat exchangers, burners, fan blades can reduce you’re the life of your furnace in a number of ways:

Restricted airflow from dirty filters can make the system work harder

Imbalanced fans can affect the life of motors

Less efficient heat transfer from heat exchangers can make the system work harder

THERMOSTAT SETTINGS

Your personal comfort preferences can affect the life expectancy of your gas furnace. The U.S. Department of energy recommends setting your heating system thermostat at 68° Fahrenheit during the winter for both energy efficiency and adequate comfort.1 Keep in mind that a thermostat set too high or too low can make the system run more frequently, which can reduce its lifespan.

HOW WILL I KNOW IF IT’S TIME TO REPLACE MY HEATER?

Regardless of how well your home heating system is made and how well you maintain it, the day will come when it has reached the end of its usefulness. Here are some warning signs that your heating system may need to be replaced:

Frequent service calls

Expensive repair bills

Uneven temperatures

Inability to stay at the thermostat’s temperature setting

Heating unit blowing cold air

New or increased noises

Increase in energy bills, especially for highly efficient heating units

WHAT OUR CLIENTS SAY...

Jim Blake of AJ Michaels has been a pleasure to work with and appreciate his professionalism and competence in both repairing a heating issue as well as an AC issue. I have engaged many HVAC companies and techs over the years but have finally found someone that can get the job done and stands by his work. Thanks!

Yaakov Feinstein

Awesome install of multiple mini-splits! My house has some pretty high walls, and they tackled the job perfectly. Very happy customer here.

Jack Rodriguez

We used AJ Michaels maybe 9 years ago to replace out AC/Heating Unit. They id a great job. This year, we used them to install a Mitsubishi split in our Master Bedroom. They were professional, affordable, polite, timely, pretty much everything you could ask for. We'll use them again if a project comes up.

Laure Ruth

The new heat pumps work well, installation looks great.  Workers were prompt and efficient.   I will certainly use this firm in the future.
