We employee only licensed technicians & electricians that specialize in residential & light commercial service & repairs.

We have 5 dispatchers on staff to quickly assist you & schedule your service request. Our phones are also answered 24/7 by a company dispatcher that can assist you with scheduling. We service all Brands of HVAC equipment & we are a Carrier Factory Authorized Dealer.
"We had an emergency and we agreed for them to perform work while we were away. Speedy Electric and A/C stated they performed work but we suspect they never did and they have refused to provide us a copy of the receipt, proof of the work performed, and information on warranty for their work. Additionally, they charged us $800, which I now know was roughly 40% higher than the five other electricity and HVAC companies I've now spoken with in Ellis County. Shame on me for trusting Speedy Electric and A/C without calling for other quotes. When we've called multiple times to obtain a copy of the receipt showing proof of their work, we get put on hold for 5-10 minutes only for someone to come back and tell us that they're too busy to find the receipt and to stop calling."

"This was a tough job by anyone’s standard. ElectricMan was very responsive to my call and sent David out to the house to do the work the day after I called. They let me know when he was coming via texts and he was on time, practiced social distancing and after assessing the fan installation as well as the new switch, was able to complete the installation. The fan installation went as planned and required a larger hole for the fan unit. He cut the hole so it would be easy for the drywall to be replaced. As the old exhaust fan (circa 1989) only used four wires, he had to fish two new wires from the new fan unit to the switch so it could operate the additional controls, which was difficult to say the least, but he got it done. The new exhaust fan is operating per manufacturers spec’s and he left the house clean and in good order. What could be better. I couldn’t be happier with my experience with David and ElectricMan. I had used another big-name company for some past electrical work, but no more. I am planning on a couple of other projects for ElectricMan to do the work on and highly recommend them to anyone."

"HR Phoenix Review This will be long but worth the reading if you are considering this company. I had a electrical outlet issue with caused 3 ceilings failures. The first day they came out they did not find it and I was told they will return the next day. The next day they continue to troubleshoot and told me I needed my circuit breaker panel replaced because it was old and they could not touch it. 5 days later they replaced it but issue remained. They requested final payment for the CB panel replacement because the work was completed. So at this point I paid $600 for the first visit, $7K for the CB panel replacement and the issue remains. They told me they would return. Since they did not label the CB panel I traced the power (their job) to label the panel and found several plugs mis wired to 240 V instead of 120 V. The tech came out corrected the issue and I found out the job really was not completed because they did not install the serge protected on the CB panel because they have the wrong one. So they knew the work was not completed when they asked for payment! They found the original issue and it was they first wall outlet (that I pointed out the first visit) the tech showed me the burned faulty outlet. So the CB panel did not need to be replaced at all. I call the office with this information and to justify the replacement they told me the CB panel was sparking. At no point during this 2 1/2 ordeal did anyone say there were sparks or any fire hazards. If this were true (which it was not) this company did not notify us or warn us and between the visits it was 5 day to get on the schedule. So if we go with their excuse they left us in a danger/situation without telling us. This company can not be trusted to provide honest/accurate assessments. And to add insult to injury they tried to bill me $400 more for the last visit. The owner Paul Rylee was aware of everything so HR pls don't respond here when there was no real response when I spoke to your office! They can not be TRUSTED!"

FAQs for generator installation projects in Sunnyvale, 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
