Conventional wisdom says that every major piece of machinery or equipment, such as a vehicle or gas furnace, requires regular maintenance in order to function properly and to realize its expected useful life. However, especially in the case of gas furnaces, we don’t usually hear why regular maintenance is important. Because of this, many people may assume that it’s just a way for furnace service contractors to make more money. This couldn’t be further from the truth! An unmaintained furnace likely leads to more high-cost repairs, and eventually the premature replacement of the furnace. These are areas where a furnace contractor makes a profit.
In reality, here at HeatSource Mechanical, we don’t make a profit when we perform a gas furnace maintenance. Why do them? We hope to develop long term relationships with our clients by providing a low cost, high-value maintenance service. The reality is that every furnace, like any piece of mechanical equipment, will eventually fail. The key is to do everything we can to make sure the equipment functions optimally for as long as possible. Here are a few ways that ignoring regular maintenance harms your gas furnace and poses a potential safety hazard to your family:
- My Blower Wheel is Dirty?
- Dangerous CO Gas Released into Your Home
- Clogged Filter
- Negligence Voids the Manufacturer’s Warranty
- Dirty Blower Wheel: A dirty blower wheel can cause several problems.
It reduces airflow generated by the wheel, meaning the blower motor has to work harder and can fail as a result. Reduced airflow can also decrease the comfort of the home and cause the furnace’s heat exchangers to overheat and fail. Also, because the blower motor has to work harder, it will use more electricity, reducing the efficiency of your heating system. A dirty blower can also be unbalanced, putting further strain on the blower motor, further increasing the likelihood of failure.
- Dangerous CO Gas Released into Your Home:
As part of regular maintenance, a gas furnace technician will check your furnace for CO gas levels. Carbon monoxide gas (CO), also called the “silent killer,” is tasteless and odorless and can be harmful or fatal at high levels. Heat exchangers in gas furnaces can develop cracks over time, through which CO gas is released. By having regular maintenance performed on your gas furnace, you will ensure that your home and its inhabitants are safe from these harmful exhaust gases.
- Clogged Filter: A clogged filter can cause a lot of problems for a gas furnace, reducing its efficiency and lifespan.
When a filter becomes clogged, airflow through the filter is reduced. This causes the furnace blower to have to work harder, meaning it will use more electricity and be more likely to fail. System short cycling due to overheating also causes the premature part failure of heat exchangers, igniters, high-temperature limit switches, and others. Reduced airflow will also cause problems with comfort and air quality in your home. As your filter becomes clogged and less air is allowed to flow through it, its ability to remove particles from the air is reduced, meaning the air in your home will contain more unfiltered contaminants. We recommend changing your furnace filter every three months or at an absolute minimum twice a year. If you have a lot of pet dander, dust, or other contaminants in the air in your home, you may consider changing the filter more often.
- Negligence Could Void the Manufacturer’s Warranty:
Most gas furnace manufacturers’ warranties require regular maintenance, just like cars (imagine if you drove your car for five years before changing the oil). If your gas furnace fails due to prolonged negligence, it could void your warranty, piling onto an already unfortunate situation.
Avoiding these issues will help you be on your way to a clean, efficient, effective and SAFE gas furnace for years to come. HeatSource offers comprehensive precision tuning for gas furnaces. Contact us today to find out more information.
