"Cody and his team were fantastic. From the drawing board to install they were patient, walked us through the entire process, and communication was top notch with explanations and answers when we needed them. They went the extra mile on this job. Good professional contractors in any trade are few and hard to find these days but these guys exceeded our expectations. I 100% recommend Kaiser Electrical and will continue to use them for any and all future electrical needs. There is no electricity on this site and they even worked with the electrical provider to get it right so I didn’t have to. "

"We had a signed agreement for electrical work, I paid half up front, and on the very morning they were supposed to show up, they called to say they ?couldn?t do it for that price? and wanted more money. In my opinion, that?s unprofessional and felt like a bait-and-switch. If you can?t stand by your own quote, don?t take the job and my deposit. Pulling this stunt on the day of service showed, to me, a complete lack of reliability and respect for customers? time. I?ll gladly take my business elsewhere, and I think others should do the same."

"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

"I wanted a portable generator and RV hookup for my house. In order to do so, I needed a larger panel with more space to accommodate the new circuits and the lockout switch. Ramon did a great job on the installation, and I now have everything I need to hook the generator to the house or hook up the RV."

FAQs for electrical wiring or panel upgrade projects in Montgomery, TX

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.
