"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."
"On both appointments, the technicians (David the first time, Matt & Evan the second time) were respectful and honest, very well organized. And they arrived right on time. We had ceiling fans and recessed lighting installed. They kept the work areas clean. -Frank K., City of Gambrills. My wife and I are very happy with their work, and the jobs were completed in the quoted time, even early! Everything was well explained and questions were answered with the feeling that they weren't in a rush to leave until I was satisfied. We will call again for future jobs."
"Outstanding service. I originally needed an electrician to determine why I lost power to ½ my house. What Jody uncovered was a defective circuit breaker and my main switches overheating and in the process of melting down. He was able to change out the panel and install new breakers immediately. I’m grateful for the prompt response by Gene and the professionalism of Jody and Brian."

"I wanted to use a locally owned electrical company, if possible, and was very happy to see the number of very good reviews for Evergreen Electric on Angie's list. I called early in the morning and Evergreen Electric was able to work me into their schedule on the same day which I was very grateful for due to the safety concerns of not having properly working smoke alarms in my house. Thad Sale and his assistant showed up at the appointed time and changed out the six smoke alarms very quickly. They also changed out one I had forgotten about (basement) while they were at my house. Also, Thad Sale gave me an estimate for a potential new electric project which seemed very reasonable. Evergreen was very professional and answered all my questions. The work was done very quickly and I feel much safer having properly working smoke alarms in my house. I would definitely call Evergreen Electric for my next electrical project.
"Awesome! I wanted to do a heavy-up at my new home. I shopped around and got quotes from several companies incl Tim. I chose Paradise because of the price, responsiveness, and professionalism that Tim conducted himself. The job called for significantly more work than expected because of my desire to eventually add a backup generator, Tim made sure that I would not need to reinvent the wheel later and installed the right equipment to meet my future needs. During the course of his work I decided to add several additional outlets and discovered a mis-wired light. He took care of all of the work in short order. Tim is officially my go-to electrician."
"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."
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.
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.
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.
The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.
Generator costs can be broken down by type:
Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000
Partial-Home Generators (9kW–20kW): $2,000 to $6,500
Whole-House Generators (22kW–48kW): $5,000 to $18,000
To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
