"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."

"They want to work and get pay by hour,but have an open end,I don't want to pay too much to working on a few hundreds dollar generator,and then if he can't not fix after 2 hrs,what can I do?still have to pay $200.00(or more) for nothing.I think if they have a quote for the job,it will be better.(note:my generator is almost new,use less than 1/2 hrs)"

"The guy was on time and nice enough, if a little standoffish. That's okay, I don't like pushy salespeople, either.  But he seemed reluctant to give me any information at all. I said I wanted to install a system as soon as possible, he offered "maybe in the spring." It's the dead of winter right now. Every other contractor I've had out is willing to do the work next week. Again, standoffish and strange.
He had no pamphlets, no brochures, and nothing to sell. I didn't learn anything about the company or the kind of work that would be done. I'm not at all sure what systems he was going to send me proposals for, but it's been two days, and he hasn't sent me the proposal yet. I've already got three other proposals within the same two day timeframe, have made my decision, and am getting it installed next week. Dynatemp has still sent me nothing. I guess they were way too busy.

UPDATE - Since posting this review, the company has responded by email and apologized for the delay. I've changed the grade of the overall experience so as to not unfairly weight down their overall grade.

UPDATE #2 - I see in the response section that they're saying the guy came out on Thursday. Not true. I even looked at my phone records to confirm it. The guy called me Wednesday at 12:26pm to say he'd be there within half an hour. He was there at 1pm on 2/13. I posted this review on Friday late afternoon, 2/15, well beyond a 48 hour period. Only then, after the negative review, did I hear from them on Saturday morning. I even conceded a bit and updated my review to give them a B grade to reflect such! I'd be weary of dealing with a company that argues over the day they showed up."

Generator Install FAQs, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

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 amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.
