Frequently Asked Questions

How do I know if my home needs an electrical panel upgrade?

If your home experiences frequent breaker trips, flickering lights, or struggles to power new appliances, it may be time for a panel upgrade. Older homes with 100-amp panels often need upgrades to 200 amps or more to handle modern electrical loads.

Do I need a permit for hot tub wiring?

Yes, most cities, including Centennial, CO, require permits and inspections for hot tub wiring to ensure code compliance and safety. Harmony Electric handles all the necessary permits for a smooth installation.

Can I install an EV charger in my garage?

Absolutely! We install Level 2 EV chargers in garages, driveways, and even commercial spaces, ensuring safe and code-compliant wiring. We work with all major brands like Tesla, ChargePoint, and JuiceBox.

How much does it cost to install an EV charger at home?

The cost of EV charger installation varies based on your home’s electrical system and the location of the charger. Harmony Electric offers free consultations to provide an accurate estimate tailored to your needs.

Why should I hire a licensed electrician instead of DIY?

Electrical work requires expertise and proper permitting. DIY electrical projects can lead to fire hazards, code violations, and expensive repairs down the line. Hiring a licensed electrician ensures the job is done safely and correctly.
