"Absolute waste of time and money. I scheduled a very simple job - replace two exterior wall sconces (porch lights) with two new ones. The old ones work fine, we just want to update the look. Scheduled service for a date and time and acknowledged there is a $69 service/trip fee which is waived if you have them do the work; no problem. They even called day-of to see if tech could come out earlier than scheduled, which worked fine. When tech arrived, I explained the very straightforward job I wanted done. He looked over the new parts, and I thought we'd be good to go. Then he said that before he did anything he had to do a "safety inspection." An hour later he quoted me a multi-thousand dollar bid to replace all sorts of equipment I had no interest in replacing. And the simple job, if he did just that, would be over $550. I declined, and so it cost me $69 to have no work done and waste my time. I will either do this myself or find a local handyman. Avoid this company like the plague."

We are A-1 Plus Electrical, a Company committed to our client's projects and needs for the Texas Houston and Dallas metro areas. With more than 14 years of experience in the electrical field. Our team has built a solid reputation in the community for our outstanding attention to detail and superior customer service.
"We are doing major remodeling and a new addition onto an older home. This company was like a breath of fresh air after dealing with multiple contractors who did sloppy work. Justin obviously knows what he's doing. A previous contractor had wired some electrical receptacles incorrectly, so what should have been a 110 receptacle was actually 220 -- a potentially lethal mistake that fried a couple of small appliances. Justin was able to fix this dangerous situation inside of five minutes by switching some wires around in the breaker box. He did exactly what he said he was going to do. He always called in advance, showed up on time, his workers were very efficient, and they kept the work area clean -- all for a very fair price. They lined up all of the recessed lights perfectly, relocated a chandelier, and relocated several receptacle boxes. Justin and his team are competent, conscientious, and courteous workers who care about doing neat, quality work. We would definitely hire this company again."

FAQs for generator installation projects in Houston, TX
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
