Benefits of Regular Heating System Maintenance

What can you expect from your newly tuned-up HVAC system?

Safety First

Safety always comes first. Cracks can develop in the heat exchanger of your furnace, jeopardizing your family’s safety. Carbon monoxide gas can escape from these cracks, and your air will become poison. Short circuits can also develop if you fail to maintain your HVAC unit. Faulty electric connections can result in a fire.

Lower Energy Bills

Regular maintenance will save you big money in the long run. A neglected heating system will have to work harder over time to keep your house cool, costing you a lot more on energy bills.

Fewer Repairs

If you notice a strange odor or sound coming from your furnace, this can be a sign of possible damage in the system and should be taken seriously. Calling a certified technician immediately can help prevent the problem from escalating. Regular maintenance on your heating system will ensure that each part of your furnace runs smoothly, preventing a bigger problem in the future.

Equipment Lasts Longer

The reason why an entire HVAC system breaks down is because of individual parts that get neglected. Our service techs will inspect every aspect of your furnace and perform any needed maintenance so that the entire system lasts longer.

Why Is Furnace Maintenance So Important?

Your furnace is very similar to the motor in your car - if you never change the oil, the engine will quickly wear out. The same rules apply to your furnace. Preventative maintenance on your furnace will keep your HVAC system up and running all winter long with no surprise breakdowns.

Maintenance Tasks You Can Do Yourself

Your heating system should be serviced annually at the very least, and if your system has a heat pump, it should receive maintenance twice a year. There are a few maintenance tasks you can perform between scheduled maintenance to ensure your system runs smoothly until the next professional visit:           

  • Change the HVAC air filter every month. Some units have an indicator light that tells you when the filter is getting clogged and blocking airflow.
  • Remove debris from around the outdoor unit.
  • Hose down the outdoor unit when dirt begins to accumulate on it.
  • Trim back foliage to at least 18 inches from the outdoor unit.
  • Keep supply and return registers unblocked by drapes, rugs, or furniture.
