"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, he is a licensed electrician and he changed all of my old s12 sockets to energy efficient sockets so that I could use my electronic devices and not blow circuits. I was being charged each time I called in a help ticket. So I called Mason Electrical Services and had him come out and take a look . He came out and took a look at the problem and gave me an estimate .and I was really satisfied on the price. He arrived promptly on 8 March 2014 had everything he needed to work with, and completed the work it only took a couple of hours and the job was done. In that time he installed a ceiling fan in my bedroom with a remote. He didn't make a mess. I would definitely recommend him to others needing electrical services in the future.
"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."
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.
You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
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.
You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.
