"We got them as a referral when it was still ANGIES LIST. A couple of days after it was installed the light had started going out the fan was working okay but the lights kept going on and off every 2 minutes, they sent the same technician out trying to figure out why it was doing that. They didn't charge us a dime for the 2 and a half hours the technician (Jason) was here. It was incredibly nice for George Willy to not charge us for having Jason here for almost 2 hours. Nice gentleman, very good technicians, and they really know what they are doing."

"Bob McGinnis 2:46 PM (0 minutes ago) to me TriStar just finished the installation of my new Generac 22kk standby generator and I couldn't be more pleased. From John, who came out and sized up the job (and made sure I passed inspections) to Amanda, who was always there to answer my questions and schedule crews to come out to top-notch electricians, like Todd and Brendon, who did a stellar job - it was clear this was a top-notch company. Communications were excellent - via email, phone or text - and they were always on time. It was a lengthy journey since I had the worst-case scenario of needing my gas line and gas meter upgraded. Navigating the BGE waters to get this done was challenging, to say the least, and TriStar has an excellent plumbing partner that worked closely with me all along the way. When all was said and done and that generator fired up today I knew the time, money and effort was worth it. Highly recommend them!"

"It couldn't have gone better. Mr. Taylor contacted me, as soon as I submitted my job request. We agreed on a date and time. Mr. Taylor arrived on time and explained what would be involved in installing the recessed lighting. What a fantastic job!! I decided to include my kitchen at the last minute and Mr. Taylor agreed, even though it required him to make a special trip to Home Depot. I could not be happier with the job. I would recommend recessed lighting (Love, Love, Love these lights) and Mr. Taylor any time. He will be my go to electrical guy from now on."

"I contracted Level Home Services through Costco for a full A/C and furnace replacement and have been satisfied with their service at every point so far. The initial inspection to get a quote was extremely thorough and informative, and they gave me several options at different price points, all of which beat the other vendors I was looking at. When it was time to actually complete the work, the technicians were prompt, professional, helpful, and courteous. After 2 full days of work, they walked me through everything they did in detail and answered all my questions. By the time they left, the only sign anyone had been here was the shiny new equipment in my basement and yard -- no mess/dirt anywhere (except my own). It was a big job so it was pricey, but definitely money well spent and I would not hesitate to hire them again."

"Terrible. Scam Artist. I was supposed to just get a cleaning AFTER another company came to unclog my AC pipe. Somehow after they come to clean they turn off my heat (which was never an issue) and are telling me i have $1,000 to repair it. PLEASE BEWARE. I'm filing a complaint with the BBB and possibly the courthouse. The owner says he knows for a fact his Technicians don't lie. That speaks volumes being its a lie."

Generator Install questions, answered by experts

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.
