Why should you choose a professional to perform your Fall HVAC Maintenance?

Fall is officially here in South Bend, accompanied by that little nip in the air that serves as a regional signal that it’s time to get ready for winter.  The leaves begin to change and animals are getting their food stash ready for winter. This is your signal too that it is time to have a professional perform fall preventative maintenance on your HVAC system.

When the cold weather hits, your HVAC unit will start working overtime to keep your home or business warm and comfortable. The colder the weather the harder it works and a system that has not had proper fall maintenance is at risk of breaking down just when you need it the most.

Preventative Maintenance done by a professional ensures the following:

  • Fewer breakdowns. When your system breaks down, you not only have to foot the bill for costly repairs, including parts and higher labor costs for an emergency call, you may also have to endure a costly shut down to your business while the system is being fixed. 
  • Improved Efficiency. Dirty filters and ungreased or broken parts can cause your system to work much harder to keep your building comfortable.Annual efficiency loss for normal system use can be five percent or more but a tune-up can counteract this loss.
  • Better for the Environment. A well-maintained HVAC system consumes considerably less fuel and other resources. This means more green for you and a greener environment.
  • Longevity of your equipment. You can expect about 14 years of service from a heat pump or air conditioner and approximately 20 years of service from a furnace. Regular maintenance reduces the risk the risk of early equipment failures and costly upgrade needs.
  • Identification of faulty parts. A mechanical system experiences inevitable wear over time. Regular HVAC system maintenance allows for worn out or broken parts to be repaired or replaced as needed.
  • Cleaner air. Through normal occupation in a home or business building, we generate a great deal of contaminants and air pollutants, such as dander, dust, and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the ductwork. While a contaminated HVAC system doesn’t necessarily mean unhealthy air, the situation may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies. With regular system maintenance such as regularly changing filters and cleaning the system will remove these pollutants.  The people spending their time in the building will be healthier and will have fewer sick days.
  • Safety. When things go wrong in an HVAC system, there can be dire consequences.  Electrical systems can cause a fire and problems with the unit can lead to a carbon monoxide leak.  Technicians know what dangers to look for and can ensure the safest operation of your system.
