"Anthony and his team do expert electrical work of all kinds. We are a 145 year old non-profit organization with buildings and grounds, and have contracted with Technician Engineers Group (TEG) on two large projects (and several small ones) over the last 15 years. One project rewired a large 125 year old building listed on the National Register of Historic Places, and one installed an extensive outdoor lighting system. In these two unusual situations TEG worked closely with us to find innovative solutions to our unique needs. We are very pleased with the results, enjoyed their can-do approach, and highly recommend this company for any electrical challenge. We found TEG reliable, honest, on time, and all the work was completed ahead of schedule."

"Ron Ethridge has been our Electrician of chose for the past three years. I started out using Ron to service my generator after the warranty lapsed. Heâ  s provided that big company expertise with that small organization connection. Since that time Ron and his team have provided electrical services for our entire home. I feel comfortable leaving Ron in our home while weâ  re away which is a huge feat for me particularly. Iâ  m grateful for the service that Ron and his team continues to provide to our family."
"I ended up hiring someone else who could install a ceiling fan as Paradise Construction was afraid of needing to tear up a large section of the ceiling and I didn’t want to create additional work and expense."
"The original (2002 construction) air-conditioning equipment was cycling on and off too frequently. Dynatemp checked the hvac systems and determined the correct replacement equipment needed to service the square footage of our townhouse. They gave us a detailed written estimate for the purchase and installation. Dynatemp offered several dates for the installation. They got the town permits needed for a crane, arrived before the crane, checked that the sidewalks were properly taped off, and prepared the old units for removal. They changed the underlying pads and installed the new units on the roof and then installed the new condenser coils. (The furnaces did not need to be replaced at this time but they made sure that the new units would work with the current and any future equipment.) They installed new thermostats better matched to the new equipment. They did not program the thermostats for us (for our security) but did explain how to do it. They left the manuals with us also. This project involved quite a few workers from 8am to around 6pm before they were completely done. The next day we smelled gas near the new condenser coil in the garage unit so we called Dynatemp. They sent an installer even though it was late afternoon Friday. He tested all the connections and found a small leak in one of the hose attachments which he was able to fix it quickly. He then rechecked the unit. We were very relieved and grateful that he came right away. "
"Everything was fantastic, I was very satisfied with the work - I am really in love with the lights that they installed. I would highly recommend this company to friends and family or anybody that wants to hire an electrician."
"It went very well. Tony is very responsive, courteous, and goes out of his way to make things convenient for the customer. Not only is he very competent and thorough in his work, but he also did a lot of the leg work, picking things up at the electric supply store, returned a couple things that I had incorrectly purchased there in my own trips prior to hiring him, and even went there on my behalf for a bed lamp that needed a new contact. He disconnected it, brought it to the store, took a trip back to the store a week later to pick it up, and reinstalled it for me. Tony could have applied a trip charge for each of the many visits he made to my place but didn't. He also took the time to explain options, solutions, and even gave me a bit of free schooling in electrical work. I highly recommend him and his business.
"He was fabulous and did a great job. It was a 20kw generator. He was very professional and came in uniform. He was thorough in discussing my options. He was able to install this in my basement instead of hanging it outside. The main reason why I'd recommend him so highly is that the unit I have is a big generator. I have it setup to run on propane. It turned out that the gas company did not lay the line within the county codes. Jim caught that and notified that. They argued with him, but the county came out and determined that it was potentially dangerous. The gas company had to redo the installation for free. He could of just finished the installation, and I would not have known the distance."
A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home.
While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.
If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.
