Keep your home toasty warm with some simple furnace maintenance tasks
Electric furnace maintenance requires changing your air filters every three months to maximize efficiency and reduce strain on your heating system.
Expect to pay $10 to $20 for drum humidifier filter replacements monthly if your whole-house humidifier connects to your furnace system.
Annual electric furnace maintenance includes cleaning your access panels, vacuuming the motor and fan, and checking that your heating elements work correctly.
Hiring a local HVAC technician professional provides reliable support for annual inspections and tune-ups, helping you spot minor issues before they become serious.
Make sure your heating system stays at peak efficiency with our top electric furnace maintenance tips. Aside from quick and easy monthly cleaning, you can optimize furnace performance and save on repairs by changing the air filters, lowering the thermostat, and having a pro complete annual inspections.
In the fall, just before you use your furnace regularly, remove all the dirt, dust, and debris that builds up in the access panels with a vacuum and a long attachment. In an ideal world, do it twice a year—once in the fall and the spring.
While cleaning the inside of the furnace via the access panels, take the time to run your vacuum over the motor and fan. Wipe the fan blades (if accessible) with an anti-static cloth.
Staying on a schedule to change the air filters every three months helps maximize efficiency and minimize energy costs. Replacing filters is a quick and easy job that reduces strain on the furnace.
If your furnace is on most of the time, your household likely generates a lot of dust. If you have a family member sensitive to airborne allergens, changing the air filters every month is a good idea. You can also check how long your filters last by reading the instructions.
Once a month, get your vacuum with the trusty long nozzle attachment and clean your air ducts. Simply remove the duct covers and vacuum inside the cavity. This gets rid of dust, dirt, and bug fragments. There are many advantages to cleaning the ducts monthly, including reducing allergens and eliminating foreign particles that can cause an obstruction.
The Environmental Protection Agency states, "Indoor pollution sources that release gases or particles into the air are a primary cause of indoor air quality problems in homes.” Cleaning the ducts regularly removes potentially harmful particles, but you’re more likely to spot something detrimental to your family's health, such as mold, and get it under control as soon as possible.
You can also opt to have your air ducts cleaned by a professional every three to five years.
It’s important to have your furnace inspected and serviced annually to keep it in good working order. Yearly inspections usually include a basic tune-up to optimize your furnace performance. Additionally, your local HVAC technician will spot any minor issues and fix them before they become serious.
A furnace inspection costs $60 to $85 on its own, but you can get it as part of an HVAC service contract, an excellent way to save money on heating and cooling inspections.
As a professional, I'd never miss out on routine servicing for my heating system. It's really easy to skip servicing your unit, but it can lead to breakdowns and high energy bills. It can be a safety issue, too.
You might have to wear a sweater, but turning the temperature on your thermostat down by a degree or two can save you costs on your energy bill and reduce the strain on your furnace. The US Department of Energy states that lowering the thermostat by 7 to 10 degrees for the eight hours you're asleep can save you up to 10% on your annual heating bill.
You can further optimize your thermostat settings by upgrading your regular thermostat to a learning model. These units are programmable and smart, so they can learn your routine and turn themselves down when nobody's home.
If you pay multiple electric furnace repair bills yearly and your energy bills are climbing, it could be time to upgrade. Older units may only be at 55% to 70% efficiency. Modern electric furnaces are up to 98.5% efficient, so upgrading to a newer model is sometimes worth reducing your home’s carbon footprint and saving on energy bills.
Depending on where you live, you may also be entitled to rebates and incentives to reduce the cost of replacing your furnace. If you're unsure whether you should upgrade your system, what your best options are, or what incentives and savings are available in your area, consult a nearby HVAC installer who can advise you.
It's worth spending a bit more money up front to get an HVAC system that is really efficient and reliable. High-efficiency heating will save money over time and decrease your impact on the environment.
Whole-house humidifiers connect to your furnace, regulating humidity and improving air quality in your home. If you have one, cleaning and maintaining it properly is important. Otherwise, you might have mold and mildew inside your humidifier, which could spread to your ductwork.
There are several kinds of whole-house humidifiers, each with different maintenance requirements. For example, drum humidifiers require filter replacements about once per month, which cost between $10 and $20. Flow-through humidifiers, on the other hand, don’t need filter changes as frequently. But regardless of which type you have, you should have it serviced annually.
It’s also essential to monitor the moisture levels in your home. Aim for an indoor humidity level between 30% and 50% to prevent mold and mildew growth.
In an electric furnace, electric currents pass through the heating elements, which creates heat and warms the air that circulates through your home. If these elements don’t work, you won’t have heat—so it’s wise to check them as part of your electric furnace maintenance routine.
Over time, your heating elements can wear down, burn out, and stop functioning. Sometimes, they can corrode and develop cracks. If one (or more) of your heating elements appear worn or won’t turn on, call a local furnace maintenance pro to diagnose and fix the problem.
Your thermostat is a pivotal part of your HVAC system, letting you control when your heating turns on, how long it runs, and how warm it gets in your home. Furnace maintenance involves ensuring that yours has fresh batteries and looking for signs of a broken thermostat.
Common problems include a thermostat that won’t maintain its programmed settings, warm your home to the correct temperature, or complete an entire heating cycle. If you notice any of these issues, contact an HVAC pro for help.
