"I hired Amperial Electric to install an EV charger and install a secondary panel, as my main electrical panel was full and was not rated to allow twin/tandem breakers. I could not be more satisfied with the experience! Chance, the owner, was professional, knowledgeable, and incredibly thorough in explaining everything to me. As someone who isn’t well-versed in electrical systems or code, I really appreciated his attention to detail and patience. Unlike many of the big-box companies I received quotes from, Chance’s follow-up was prompt, respectful, and completely pressure-free. That alone made a big difference. The fact that he is fully licensed and insured was also a major factor in my decision—peace of mind was important to me, and he delivered. Chance is clearly passionate about what he does and takes pride in doing things the right way. If you’re looking for someone who stands by their work and genuinely cares about quality and safety, I highly recommend Amperial Electric!"

"Electrical Technician Alvaro Zuniga was very helpful and efficient. He installed upgraded GFI outlets in basement, kitchen and bathroom. He also was able to locate and rewire hidden doorbell, and transformer and chime to enable the replacement of battery Ring doorbell to an upgraded wired Pro2 Ring doorbell. I’m extremely satisfied with his timeliness, proficiency, knowledge and helpful advice."

"Forget the rest, go with the BEST, TOM @ MODERN AIR. Tom, the owner of Modern Air, contacted me immediately after I put in a request with HomeAdvisor. I explained my problem to him & he suggested that we meet the next day at 11 AM. At EXACTLY 11 AM, he arrived (was shocked). He immediately went to work diagnosing my concerns. My main A/C unit was less than 2 years old, but my air handler was 10 years old (probably on its last legs, my opinion). I could not get the temperature below 80 degrees. He found that the freon was at 1/3 the recommended level. He recommended a coil cleaning before doing a leak test. I gave him the go ahead & he did a GR8 job, with a professional cleaning solution & tools. I had done a 'do-it-yourself' coil cleaning a couple of months ago & was astonished at the amount of 'crap' that came off the coils. I won't do that myself again. He then did a full leak test with 'state of the art' equipment on the main unit & handler & could only find a potentially small leak in the air handler coil. As he felt that the leak was VERY small, he suggested (& I agreed to) infusing a leak sealer/dye chaser into the system. He felt that this would hopefully resolve the issue & if not, at least identify where the leak would be located. AT NO TIME DURING HIS SERVICE CALL, DID HE TRY TO SELL/UPGRADE me on a new air handler or anything else for that matter (VERY big surprise). He also corrected some wiring issues with the water evacuation pump & reprogrammed the thermostat, both for FREE (I had personally done a poor job installing a new evacuation pump last year). He proceeded to replenish the Freon to the correct levels. He then thoroughly cleaned up any mess that was created during his coil cleaning & other work done. We sat down to review exactly what he had done & the related the material & labor cost of the service call. I was blown away, not only by his professionalism & conscientious service, but also the reasonable cost. Unlike many other service persons that I have dealt with in the past, he definitely wasn't trying to rush the job to get to his next appointment or upsell me on replacing something that wasn't needed. Tom really knows the "long term future" value of customer service & professionalism. BOTTOM LINE, it has been 10 days since his service call & I am sitting in my den with a sweater on, its 92 degrees outside & my wife is talking to me again. Would I call him again for annual maintenance or service? Would I have him replace the air handler when the time came? WITHOUT HESITATION!!!, he is in my phone's speed dial. Damon R. in Lar"

FAQs for electrical wiring or panel upgrade projects in San Antonio, FL

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
