What should I do this week when two electricians disagree?

Ask each electrician for a written load calculation showing the home's actual service demand. Compare the numbers, not the opinions. Ask how the calculation accounts for planned appliances like EV chargers, heat pumps, or a hot tub.

What factors determine panel size?

The home's actual load determines panel size, based on a load calculation. HomeGuide notes most homes need at least 100 amps, while newer homes often need 200 amps or more. Future needs also matter, since the Austin guidance recommends sizing for current and future loads.

What are the future-proofing benefits of 200A?

A 200A service gives room for new appliances or future electrical loads without another upgrade. Austin guidance says a load calculation shows whether a 100A-to-200A jump is needed. Austin's severe-weather risk also makes a correctly sized, code-compliant service important.

How do I validate a contractor recommendation in Leander?

Verify the contractor holds a Texas Electrical Contractor License (TECL) with a licensed Master Electrician on staff. Confirm the permit will be submitted by a licensed electrical contractor registered with Austin Development Services. Ask for proof of licence and insurance before signing.

What to do next

  1. Request a written load calculation from each electrician before choosing a panel size.
  2. Verify the TECL license and confirm a licensed Master Electrician is on staff.
  3. Confirm the quote includes the electrical permit, utility coordination with Austin Energy, and inspection.
  4. Ask whether the quote includes the outdoor emergency disconnect required under NEC 2023 Section 230.85.
  5. Call (737) 367-2100 or email [email protected] for a free quote from a licensed, insured electrician.
