The Value of Upgrading Electrical Wiring

Installing a new furnace and/or air conditioning system in your home is an important and exciting decision. The purchase and installation process is a perfect time for you to learn all you can about the different systems in your home.

One system that should not be overlooked during your HVAC installation is your home's electrical system. Your electrical wiring should be inspected before installing your new unit(s) because upgrading electrical wiring in your home may be necessary, depending on its age and the type of system you've chosen. 

Benefits of Upgrading Your Electrical Wiring

 

The condition of electrical wiring can decline over time. Necessary upgrades or replacements should be made prior to installing the HVAC system to ensure the electric system can safely handle the demands of new furnace/A/C unit. Here are some important benefits you'll enjoy by upgrading electrical wiring in your home:

  • Extended life of the new HVAC system – Upgrading your electrical wiring ensures that the newly installed unit will operate smoothly without interruption from old fuses, circuit breakers or wiring impeding the operation and possibly causing damage to the internal parts of the unit.
  • Compatible electrical system –  The correct sized wiring and circuit breakers will avoid equipment overload to the system. Fire hazards can be avoided with new electrical wiring, by replacing old, incorrectly rated wiring or circuit breakers.
  • Improved efficiency –  A system that is functioning properly will be more energy efficient. If your electric is not capable of handling the new power requirements of you new system, you may have problems with breakers kicking off or blown fuses. The efficiency of your HVAC may suffer from this continued restarting of the heating or cooling cycles.
  • Even power distribution throughout your home – Adding a major appliance such as an HVAC unit may draw more power. Upgrading the electric system will ensure all areas of your home will continue to have enough amperage available for all the systems and appliances you use.

The specific electrical  requirement of  each HVAC unit may be different depending on the manufacturer of the unit. If you have installed a larger unit that has additional features, it may require more power than your previous system. 

Upgrades and Replacements

 

It's a smart idea to have the information on your new unit available when you contact a licensed electrician. He/she will be able to give you the details of the required upgrades or replacement areas if any are necessary in your home. Discuss this before purchasing the new system to assure you are purchasing a system that meets your needs and will operate with the electrical upgrades that you are prepared to add to your home. Here are some common upgrades that may need to take place:

  • Wiring replacement – Some wiring may need to be replaced. If some wires have been found to be old or corroded, have the wiring checked throughout your home. There may be unsafe electrical wiring or connections, such as outlets or switches, elsewhere. Upgrading electrical wiring does not necessarily involve all sections of your home.
  • Circuit breakers or fuses – Old fuses or circuit breakers may not be available and may need to be upgraded to a newer, safer type to match new circuits that are being added for the HVAC unit. A circuit breaker box may need to be upgraded for the new circuit breakers.
  • Added  power – Additional amperage (power) may be needed to be brought into your home by upgrading the service connection from the street and upgrading your main circuit breaker box.

Upgrading electrical wiring for your new HVAC system will contribute to a smooth-running heating and cooling system for many years. The wiring should be checked in your home during the process, giving you peace of mind that your electrical system is safe, with no potential issues. This recommended safety check is especially important for homes with older electrical wiring.

The electrical inspection of your home should be done by a professional licensed electrician. There are elements involved that require experience to diagnose problems and require specialized tools carried by a certified electrician. Any safety issues can be identified and corrected so problems do not surface after the completion of your HVAC installation. Many problem-free years of enjoyable home comfort are possible when the installation and upgrades are done correctly!
