"We are extremely satisfied with our generator purchase. We interviewed several different companies and Alternative Home Energy and Maintenance was the only firm that understood our needs. They did a thorough review of our electrical and gas configuration on the initial sales call, which none of the other companies did. We were provided a detailed, line item quote. The entire team - Tasha Thompson, Jarrod Watson, Robb Taylor, Zack Martin, and James Sanders (plus a couple of other individuals whose names I don't have) were top notch. Tasha did an outstanding job in keeping us informed every step of the way. Robb did a thorough walkthrough and was a no-pressure sales rep, James and Zack did an outstanding job on the installation. I can be pretty high maintenance on jobs like this and Tasha was incredibly responsive to my texts and emails. I can't recommend this firm highly enough. A lot of folks will sell you product, but this team delivers value and customer service at a very competitive rate. Great job, team!"

Electrical wiring or panel upgrades FAQs

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
