It’s essential to regularly inspect and maintain your ducted heating unit to ensure it is functioning properly and efficiently, but even then, there will come a time when a replacement is necessary. Signs that it may be time for a new model include increased energy bills, uneven heat throughout the house, strange noises or odours coming from the unit, and a decrease in the overall effectiveness of the heating.
When there are signs your gas ducted heater may be reaching the end of its lifespan, it’s always best to consult with a professional to determine if a replacement is necessary and to discuss your options for a new unit.
In this piece, we will look closely at the signs of when it’s time for an older heater to be swapped out for newer models, as well as the process of installing a replacement ducted heating unit.
How Long Does a Gas-Ducted Heating System Usually Last?
A ducted gas heating system can last between 15 and 20 years with proper maintenance and regular servicing. The average lifespan can vary depending on factors such as usage, care, and the quality of the heating unit. Older models that are well-maintained and not heavily used may last longer, while a heater that is not maintained or is heavily used may need replacement sooner.
Signs It’s Time for Ducted Heating Unit Replacement
These signs indicate it may be time to replace your ducted gas heater:
Reduced Efficiency
The reduced efficiency of ducted gas heaters has varying causes, but the most common reason is that the unit is dirty or blocked with dust and debris. This can happen over time as dust, dirt, and other contaminants build up in the return air grille and unit and restrict airflow. The unit has to work harder to heat the home.
It can also be a sign of a malfunctioning thermostat. A thermostat without the correct calibration can prevent the unit from dispersing heat throughout the home to the desired temperature. An old unit that is less efficient is a sign that you may need ducted heating replacement.
As a ducted heater ages, varying components wear out, making the system less efficient. It’s a sign that it may be time for a replacement, especially if the unit is over 15 years old.
To ensure that your ducted heating unit is operating at maximum efficiency, scheduling regular maintenance and servicing is a must, as well as managing any fault codes or breakdowns as soon as they arise.
It’s Emitting Strange Noises
When your ducted heating emits strange noises, it can indicate a serious problem, such as wearing out fans or the unit no longer working. Some common noises include rattling, buzzing, or clicking sounds.
- Rattling noise: May indicate a loose or damaged part in the unit, such as a fan blade or a worn-out bearing. This can cause the unit to vibrate and make noise, and a professional gas heating technician should address this as soon as possible.
- Buzzing noise: This usually indicates blocked or deteriorating ductwork, which restricts the airflow and causes the gas-ducted heater to work harder to warm the home.
- Clicking noise: Likely caused by a malfunctioning fan that needs repairing or replacement.
Increased Energy Bills
Increased energy bills are likely a sign that your ducted heating system is not operating as efficiently as it should. Several potential causes include a build up of dust and dirt to the return air grille and heating furnace, deteriorated ducting, or a malfunctioning thermostat.
When dust, dirt, and other contaminants build up in the unit over time, it reduces efficiency and increases energy costs. It’s the same for damaged and deteriorated ducting. Cold air can enter the system when not adequately sealed, reducing the unit’s ability to heat the home, not to mention heat loss into the ceiling space or underneath the home.
If you were experiencing lower running costs and they’ve suddenly increased, these issues signify that it’s time for a service or a ducted gas heater replacement.
Signs of Physical Damage
When you notice your ducted gas heating system has physical damage, it’s a sign the unit is ageing. Some of this damage would include:
- Visible rust or corrosion: located on the unit’s exterior, it’s an indication your ducted gas heating system has exposure to moisture.
- Dents & cracks: Visible signs of dents or cracks on the unit’s casing indicate that the heating unit is ageing and may need replacing with a new system.
- Deteriorating ducting: While sometimes a damaged duct is a result of improper installation, it’s also a sign your older heating furnace or ducting are wearing down.
Requires Frequent Repairs
Frequent repairs on a ducted gas heating unit indicate it’s not functioning properly and may be nearing the end of its lifespan. It could also mean it wasn’t installed correctly or had regular maintenance as all major appliances should.
When you need ducted heating furnace replacement, it is likely to be less efficient, which can lead to and require more frequent repairs. It means it’s more likely to break down unexpectedly, which can be inconvenient and disruptive.
Sometimes repairs on your old heating system are part of a more significant problem that can’t be fixed by simply addressing the symptom. For example, if the unit has a thermostat issue, it may be due to the wiring or control board. In this case, consult a professional gas heating technician to diagnose the underlying issue.
The Convenience of Ducted Heating Replacement
Ducted heating replacement can be a convenient option for homeowners looking to improve their comfort and have a more energy-efficient heating system for their homes.
New gas appliances, such as a quality heating system, will provide more efficient heating, with advanced features such as programmable thermostats and improved airflow. This can lead to lower energy bills and increase energy efficiency because it uses less power consumption.
Replacing an older, outdated ducted heating unit with a newer model will also be more reliable and less prone to breakdowns, along with being:
- Covered by an extensive warranty period
- Environmentally friendly
- Save homeowners time
- More cost-effective
- Saves money long-term
- Produces less carbon footprint
