The average forced air gas furnace should last roughly 15 to 20 years. However, you can inadvertently shorten it when you do not know the factors that require your attention. learn about some ways in which you can increase furnace lifespan to get more out of your equipment in Raleigh, NC.
1. Stay On Top of Changing Your Furnace Filter
Keeping your furnace filter clean is one of the most important factors in getting a full-service life from your unit. Your furnace cannot run effectively without adequate airflow moving through your system. Restrictions, including a clogged filter, add strain from increased electrical resistance and longer heating cycles.
To keep your filter passing air effectively, change it periodically. That frequency varies based on your filter size, style, and air quality. Ideally, check your filter every month so it becomes a habit and you do not forget about it.
2. Keep a Regular Household Cleaning Routine
Your air carries contaminants that eventually settle as dust around your home. To keep it from continuously circulating, you need to remove it.
For your furnace, dusting flat surfaces around your home and cleaning your floors is important. Depending on your flooring, this may include vacuuming or mopping. Ideally, perform these chores whenever you can see any accumulation of dust or contaminants.
3. Keep Current on Furnace Maintenance
Next to your filters, annual professional maintenance is critical for getting the longest life from your furnace. Even with a good filter, the smallest airborne contaminants will still flow through it. These contaminants will settle into your system at the heat exchanger, circulating fan, and elsewhere.
Aside from cleaning these areas, your technician will also test your system to ensure air can flow uninhibitedly through the system. They tighten electrical connections and mounting hardware to prevent unusual resistance and excessive vibration. Then, they conduct extensive tests to make sure each part of the heating cycle initializes appropriately.
4. Check Your Insulation
Beyond airflow restrictions, your furnace experiences additional strain and either extended or more frequent heating cycles with insufficient insulation. The Department of Energy recommends ceiling insulation of at least R38 for the Orange area. This translates into at least 12 inches of standard fiberglass batt insulation.
Even if you had the right amount of insulation, you should inspect it annually to be sure it is still sufficient. Roof leaks, dripping HVAC ducting, and animals can all cause the insulation to compress, degrading its heat resistance.
5. Tend to Repairs Quickly
Ignoring subtle furnace problems when you first notice them is common. It could be an unusual sound, feeling like the furnace does not produce enough heat, and more. You might dismiss these signs as coincidence or be able to identify a different cause.
Your entire system experiences additional strain when even one component operates sub-optimally. Overlooking even small problems creates a compounding effect on the rest of the system. If left long enough, the final result is a degradation of your system service life.
6. Use Your Thermostat Programs
If you have a thermostat that does not have programming capabilities, it may be time for an upgrade. Whether you opt for the advanced smart thermostat or a basic digital model, look for one that allows programming. Many times they are able to sync with a smartphone app for controlling remotely.
The idea is to use the programs to drop the temperature in your home when no one is there. In addition to saving up to 10% of your annual heating bills, using programs also reduces the operational strain on your furnace. To reap the benefit, reduce the temperature by at least 7 degrees Fahrenheit for at least 8 hours each day.
