3 Most Expensive Furnace Repairs & How To Avoid Them

Is the winter cold getting you feeling the chill in your wallet? Are you dreading your next furnace repair bill? Keep reading to learn more about expensive furnace repairs and how you can avoid them, so you can save money and stay warm this winter season!

Common Causes of Expensive Furnace Repairs

Furnace repairs can be costly, so it’s important to understand the common causes of expensive repairs and how to prevent them. Some of the most expensive ones are due to parts failure or a lack of maintenance. The following are three of the most frequent causes for it, along with measures you can take to prevent them from occurring.

  1. Ignition or Pilot Control Problems: Ignition or pilot control problems account for some of the pricier repairs associated with furnaces and boilers. These are essentially electronic systems that control how much fuel is used to heat your home, meaning they require routine maintenance in order to work correctly. In order to avoid these types of problems and their associated costs, it is important that you have your system serviced on a regular basis by an HVAC professional who is familiar with your furnace’s make and model.
  1. Heat Exchanger Cracks: Many older-model types contain a heat exchanger which allows heated air from its combustion chamber to be blown into living areas through air ducts while maintaining a safe amount of space between dangerously hot exhaust gases and tender humans or pets in close proximity. Due to age or rusting from inadequate maintenance, these heat exchangers can be prone to cracking which will cause hot exhaust gases into previously safe spaces before being detected by safety valves that should shut down combustion immediately in such an event — leading us directly into our third most costly repair…
  1. Broken Safety Valves: Safety valves detect leaks in excess pressure throughout the system and shut down combustible activity immediately after sensing danger levels — making them potentially life-saving devices when functioning properly. Unfortunately, these valves can become dirty over time when exposed air contains particles that may clog up a unit’s mechanisms leading over time eventually resulting in replacement being required as even extensive cleaning cannot restore their prior performance integrity. It is therefore wise not just to inspect but also clean your safety valve at least once each year for optimal performance.

Furnace Repair Warning Signs

Warning signs of an impending furnace repair can range from abnormal noises during operation to excessive dust being circulated throughout your home. These warning signs could indicate an underlying problem with your furnace that needs to be addressed. Furthermore, if the yearly maintenance of the furnace has been neglected, it could lead to a larger repair in the future.

Knowing how to recognize the warning signs can save you time, money and reduce the amount of stress while having a functioning heating system. Here are some common symptoms or warning signs that should immediately be followed up on:

Strange Noises: Unusual rattling, squeaking or thumping noises coming from your furnace may be an indication of a serious issue occurring with its internal components.

Strange Smells: An unpleasant odor coming from it may also be a sign of issues such as overheating or improper ventilation for combustion appliances.

High Energy Bill: A sudden spike in energy bills could indicate a malfunctioning motor that is running on full power or cycling on and off abnormally frequently.

Poor Air Quality & Dusty Home: You may find yourself sneezing more often within the home due to experience dustiness and poor air quality throughout the space due to leaky filters or blockages within the ductwork.

Lack Of Heat Output/ Cold Spots: If one room is noticeably colder than others in spite of consistently running heaters this could indicate potential clogs in the HVAC system’s ducting or inadequate insulation levels throughout your property.

To ensure all these potential issues are avoided, it is recommended you get yearly maintenance checkups for your furnaces as suggested by experienced professionals nearby familiar with local climate conditions and equipment best practice guidelines.

Repair and maintenance costs can vary greatly depending on the complexity of the system and the components that need to be repaired. It’s important to be prepared for potential costs as well as understand common services that may cause costly repairs.

Common services include repairing broken parts, replacing filters, inspecting ventilation, checking gas flow and more. Each service may require specific tools or expertise which can add to the labor fees. Some of the most expensive ones include issues with ductwork, control boards or faulty wiring.

Tips for Preventing Furnace Repair

Follow these tips for protecting your system and avoiding some of the most expensive problems with it:

  1. Change your filter regularly. A clogged filter restricts airflow, taxing the system and forcing it to work harder than it should. Manufacturers typically recommend changing the air filter once a month, or at least once every three months, depending on the type of filter you’re using.
  1. Keep vents and registers clear. Make sure furniture isn’t blocking air vents in any room of your home as this will also impact airflow and potentially cause further problems with your system. Additionally, keep pet dander, dirt, and dust away from your return grilles where possible since these can restrict proper operation as well.
  1. Monitor performance levels carefully. If you notice that your home is taking longer to reach target temperature or if heating cycles seem shorter than normal, contact us right away so we can conduct a thorough inspection of the system before major damage sets in – something very common with HVAC repair issues!
  1. Invest in regular maintenance services from a certified technician like those at Lee’s Home Services Inc. Proper maintenance not only prevents unnecessary repairs but also extends your heating system’s life by eliminating small problems before they become large issues!
