The average lifespan of electric furnaces and central air units is 15 – 20 years. Some HVAC systems will need replacing at 10 years. HVAC systems that maintain regular inspections and maintenance tend to last longer which increases the return on investment for a new installation.
To prevent unnecessary repair and replacement costs, homeowners should know the most common signs their electric furnace or central air units need servicing.
When You Just Need a Furnace Repair or AC Repair
The majority of issues with an electric furnace and central air units can be resolved through a simple repair. Many of these repairs, such as replacing an air filter, can be done by the homeowners themselves. No professional intervention is required.
However, not all repairs should be attempted by a homeowner. Some problems can result in safety issues, poor indoor air quality, or system failures – all of which benefit from professional diagnosis. This professional diagnosis will determine if the issue can be resolved with a HVAC repair, or if a HVAC replacement will be needed.
Unusual Maintenance Problem
An unusual maintenance problem is something that does not happen often. Most electric furnace and central air will work at peak efficiency for years with regular maintenance. But minor issues, like a belt, can become major issues if not addressed.
Professional scheduled maintenance appointments are recommended at least twice per year to reduce the chances of unusual maintenance problems. Yearly checkups of your electric furnace in the fall and central air unit in the spring will help keep them operating in peak condition. These bi-anual checkups will also help avoid the costs of a premature furnace replacement or AC replacement. Homeowners can sign up for an annual service plan and take advantage of the discounted benefits and discounts that come with it.
Regular inspections will ensure issues like this one are caught before they cause serious damage to the whole unit.
A Foul Smell
HVAC systems sometimes emit awful smells. This is not a sign of dust or of an older unit but a sign that mold has grown somewhere inside the unit.
Turn off the unit immediately. The fans can blow spores into your home or business and cause serious health problems to vulnerable individuals.
Mold can be dealt with without replacing the whole unit. If mold is allowed to grow over long periods of time, however, the mold may spread to the internal workings. If this happens the entire system to be thoroughly cleaned.
Take note, some types of mold may not give a strong, pungent smell. A general drop in air quality is another sign that mold is present in your HVAC system. Ask your heating and air conditioning professionals for advice on measuring your indoor air quality.
Cool Air is No Longer Blowing
In some scenarios, a central air unit may be blowing hot air instead of cold air. This happens when central air units may be low on refrigerant. A professional service agent will need to schedule an appointment to refill the unit.
Homeowners should not attempt to add refrigerant to their central air system. These units utilize specific refrigerants and the wrong amount of refrigerant can destroy a central air unit.
The Thermostat is No Longer Working
Most people assume a faulty thermostat has nothing to do with their electric furnace and central air systems, which may be incorrect. There are times when the thermostat is working fine, but the unit is faulty. Broken thermostats can be a symptom of a wide range of minor and major faults with the unit. To diagnose and resolve this problem, call a professional and schedule a service call.
You Need a Furnace Replacement and/or AC Replacement
Electric furnaces and central air systems have a lifespan of between 10-15 years. Even if a unit can technically run longer, technology has typically advanced to such an extent that it is no longer worth maintaining an older unit.
Sooner or later, homeowners will require a furnace replacement and/or AC replacement. What homeowners need to know is how to tell whether a problem is serious enough to warrant a full replacement.
Your System is 10-15 Years Old
HVAC systems are reliable, but their parts are only going to last for so long. Once a unit reaches 10-15 years old, most HVAC experts recommend an upgrade even if a home’s unit continues to operate efficiently. New technology can equate to more efficiency and cost savings.
As HVAC systems age, they can become costly to repair. And they will require more repairs. If you find yourself in this situation, ask your service tech to advise you on whether you should repair or replace your HVAC system.
Safety is a top priority for any family. Electric furnaces and central air units are safe, but malfunctions can lead to fire hazards and carbon monoxide poisoning.
Recurring problems can be a sign of an imminent malfunction. The majority of malfunctions are no cause for concern, but they can still pose a safety hazard.
Regular servicing of older units can help identify and rectify these issues.
If an electric furnace and/or central air unit is making squealing, grinding, or banging sounds, there is a serious issue. It means something has either broken or something is about to break. These are often the sounds of internal components being damaged.
Sometimes, these strange noises can be resolved through a repair. Other times, the whole unit will need to be replaced.
You Experience Repeated HVAC Repairs
As your HVAC ages it will require more repairs and replacement of parts. A sign your HVAC system is reaching its life expectancy is a cycle of constant repairs.
