"They replace my AC/Furnace and a Hot Water Heater. They send out an actual HVAC Technician with installation experience to spec out and quote your system. And they help with all the rebate paperwork and submissions through the utility companies. When I said I had problems with heating/cooling in a specific area - they had the installer check the duct work and found a partial blockage that they removed. All's good now..."

On Staff Employees. No Subs. Project Pricing To Reflect The Work To Be Performed. Additional Contact: Paula Fiedler

"Please do not use this company. They are not friendly or willing to communicate. They don't care about customer service. The owner refused to discuss my issue with me. On my rental property, we had issues with outlets. My renter said they checked the breaker panel and nothing was tripped. Being that anything else is above my knowledge base, I called Fielder Electric to come out to help trouble shoot, come to find out it was indeed just a tripped breaker. They spent all of 3 minutes in my house to simply flip a switch and charged me $85 to come out there (which is fine and fair to cover the trip), but they refused to have a discussion about reducing the additional $85 full hour service charge, which totaled $170 all in, for them to flip a switch. I feel like I got robbed. There was no sympathy on the situation and basically got fully paid to do basically no work. They didn't care if they were there for only 1 minute and did no work at all. I was told "it is what it is," by the secretary and I was told the owner refused to speak or allow me to email with him. I would go with any other electrician that is willing to communicate and work with their customers and at least be heard."

Electrical wiring or panel upgrades FAQs

Installing electrical service to a detached garage costs between $1,000 and $3,800, with the exact price depending on your specific requirements and the distance from your home. This project may include a subpanel installation if you need multiple circuits or higher capacity. The complexity of your electrical needs, the garage's intended use, and your location all influence the total investment required for a properly installed and code-compliant system.

Most local building departments require permits for electrical work connecting separate structures, with permit fees ranging from $25 to $200. Professional electricians are licensed to perform this type of work in most states, and they often handle the permit process as part of their service. Skipping required permits could potentially create issues with insurance coverage or future property transactions, making proper documentation an important consideration.

For safety and legal reasons, hiring a licensed electrician is highly recommended for connecting electrical service to a detached garage. Electrical work involving separate structures requires specialized knowledge of codes, proper materials, and safety protocols. While homeowners might handle certain aspects like trenching to save on costs, the actual electrical connections should be performed by qualified professionals to ensure safety, reliability, and compliance with local building regulations.

The timeline for installing electrical service to a detached garage spans from several days to a couple of weeks, depending on project complexity. The process includes planning, obtaining permits, trenching, electrical installation, and any necessary finishing work. Weather conditions, contractor availability, and permit processing times can all affect the overall schedule. Your electrician can provide a more specific timeline based on your property's unique characteristics and project requirements.

Underground electrical installations for detached garages tend to use conduit systems rather than direct burial cables, as conduit provides superior protection for the wiring. While specific installation methods may vary based on local codes and site conditions, professional electricians often recommend running electrical lines underground via conduit for detached structures. This approach helps ensure long-term durability and simplifies any future maintenance or modifications to the system.
