FAQs

Frequently asked questions

Still have questions?

How much does whole house generator installation typically cost?

Whole-home generator installation costs vary by home and system design. We install and maintain standby generators, including wiring, hookups, testing, and ongoing service. Final price depends on generator size (kW), fuel source (natural gas or propane), transfer switch type, panel capacity, trenching or gas line work, and site prep for the pad. A licensed electrician will confirm pricing after an on-site assessment. Our Home Care Club provides annual maintenance, priority service, and reminders in Denver and Thornton.

How much does standby generator repair typically cost?

Standby generator repair cost is confirmed after an on-site diagnosis and depends on the failed part, labor time, and system setup. Most charges come from a single component or transfer-of-power fault rather than the engine. We test, isolate the issue, and share an upfront estimate; weak batteries or corroded lugs often look like bigger failures, so we load-test before replacing parts. Our Denver-area electricians serve Berkley with code-compliant repairs and careful post-repair verification. We also offer 24/7 response for outage problems with transparent pricing.

Common cost drivers include:

  • Automatic transfer switch or contactor replacement
  • Control board, sensor, or voltage regulator failure
  • Fuel delivery or wiring faults causing no-start or no-load

If you smell gas, see arcing, or the generator backfeeds into the house, shut it down and call a licensed electrician.

How much does standby generator repair service typically cost?

Standby generator repair pricing depends on the issue, parts, and the time needed to diagnose and fix it. A licensed electrician will confirm final costs on site after inspection and testing. We offer 24/7 emergency response and same-day service options. Home Care Club members receive a 10% discount on repairs.

What affects cost:

  • Diagnostic time and troubleshooting
  • Parts needed and availability
  • Transfer switch or wiring issues
  • Maintenance history and testing required

How much does it cost to install a standby generator at home?

The cost to install a home standby generator varies by home and is confirmed only after an on‑site assessment and written estimate. The biggest driver is generator capacity (how many circuits or whole‑home coverage you want), followed by installation complexity and how the system ties into your main electrical panel. We install and maintain integrated generator systems in the Denver metro, including Commerce City, with licensed in‑house electricians and transparent, no‑surprise pricing.

If you’re comparing options, here are common cost factors:

  • Generator kW size and desired load coverage
  • Automatic transfer switch type and panel integration
  • Distance from generator to panel and required wiring/conduit
  • Fuel supply work (gas line routing and meter capacity) and placement pad
  • Add‑ons like surge protection or panel upgrades if needed

For many homes, a right‑sized unit with an automatic transfer switch offers the best reliability; a site visit defines whether repair of existing equipment, a smaller circuit‑select setup, or full replacement is the smart move. Schedule an on‑site evaluation to lock in the correct size and exact installation scope.

Can I install a backup generator myself safely?

Installing a backup generator is not a safe DIY project; hire a licensed electrician to protect your home and equipment. Most issues start with incorrect wiring or missed safety checks, which can lead to shocks or equipment failure. Brothers Plumbing, Heating, and Electric uses licensed, code-compliant workmanship and verifies operation before leaving. We provide licensed generator installation and maintenance for homes in the Highlands Ranch area. For ongoing reliability, our Home Care Club adds annual maintenance plans, priority service, and member discounts.

Call a pro right away if you need:

  • New wiring and generator hookups
  • On-site testing and commissioning after install
  • Routine maintenance or repairs to ensure reliable operation
  • Emergency response during an outage

If power is out and you suspect a wiring issue, stay clear of the equipment until a licensed electrician arrives.
