"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."

"when I asked for an estimate on my ceiling fan installation, Murphy responded quickly with a time estimate, and suggested a couple of deals they had available with Angie's list. I took them up on the deal that seemed the best fit for my project, and made an appointment for the work online, so easy! The techs were on time, polite and professional. excellent work on the install, including electrical boxes and remote controls."

"I needed an electrical inspection on a 1968 home that I was in contract to buy. It had a low voltage electrical system. William provided a thorough inspection and report. I was very pleased with his knowledge and professionalism. I would highly recommend him and his company."

"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.

Generator Install FAQs, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
