"Highly recommend! Very professional, friendly, prompt! Great job, great guys. Always called and showed up as promised. Jim came to see the scope of work and discuss timing just a couple of days after we spoke on the phone. The job was done as scheduled and done perfectly. They were knowledgeable and efficient - replacing some old knob & tube wiring in a 150+ year old house; and adding some new outlets/switches where I wanted them. I will call them again when I need any electrical work done!"

Electrical questions, answered by experts

To upgrade electrical systems in older homes, you might need to reroute new wires with lath and plaster walls. That’s because it’s more challenging to get inside the walls of an older home compared to a modern home, which usually uses drywall. But there are easier ways to level up your electrical game in an older home. For instance, you can swap out an old furnace for a new electric heat pump, or you could use a heat pump for water heating.

Yes, the majority of appliances that run at 240v will work with a 220v outlet, but will often run slower and may have a slight delay in turning on. This could also cause long term damage to the appliance being used, so it’s recommended to always use the correct voltage for your appliance and upgrade to a 240v outlet if needed.

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.

Many homes have a 200-amp service, which requires a 2-inch electrical meter riser. Larger homes or homes that require more energy for several appliances and devices may have a 400-amp service. For 400-amp service, opt for a 4-inch electrical meter riser.

There are several reasons why an electrical outlet would suddenly stop working, including:

  • Broken parts in the outlet

  • Outlet burnout

  • Circuit breaker tripped

  • Damaged circuit breaker

  • GFCI outlet tripped

  • Damaged or loose wires

  • Failed connectors

  • Appliance failure
