Very thorough and informative whole house fan, chandelier and kitchen hood thru roof job. Josh explained in details and provided suggestions to protect my old circuits also.
Wanted to replace very old track lighting in living room with can lights. Submitted an estimate request on a Sunday night, Jason came out first thing Monday morning to check out the project and provided a timely and reasonable estimate later that day and followed up with a phone call. Work was completed today, one week later! Josh, Elijah, and Ricky were respectful of our home, took great care to keep things clean and were very pleasant. I don't know why we put this project off for so long! We finally have decent lighting in our living room! Will definitely use Dollens Electric for any future home projects/maintenance!

Professional, fair pricing, and stayed late to get complete the job. Excellent workmanship and could not recommend more.
These guys are great. Had power fail at one of our outbuildings; they offered to come fix it on Xmas eve but I said after Christmas was fine. They came out on time, got it fixed, all good. Highly recommended!
Excellent service & very competitive pricing. Would definitely use Dollens again & recommend them to others.
Excellent service with courteous and knowledgeable men
They have helped us a couple of times now. Will continue to use them going forward.
I apologize for leaving a 1 star review earlier. I wanted to leave a review for another electrician service with similar name.
Response from the owner: I apologize for your poor experience. But I believe you maybe confusing us with another company. We have not provided an estimate or service to Ben Yu.
The guys who came out listened to what I wanted to get done and got right on it. I’m very pleased with their work. More business to come!
Very pleasant and professional, but very expensive for 20 minutes of work.

Response from the owner: Thank You Trajan Market. Working with you guys was great. We look forward to the next project.
Dollen's Electric are our one-stop shop for anything electrical! Great family business! Give them yours!
Response from the owner: Stacie, Thank You. We appreciate your support and great review. You're awesome.
We recently bought a vehicle and I contacted Jason and he came right away. The next day his son Josh, cousin Elijah, and their friend came by to install our 240 volt outlet with precision and quality. I would go to them again.
Response from the owner: Thank you. We are so glad you are happy with our work. We really appreciate the review.
Highly efficient service. Provided the best solution to charge our new Tesla avoiding purchase of a costly charger. Installed a 50amp line and outlet. Highly recommended.
Response from the owner: Thanks Joel! You guys enjoy that new car!
We had a great experience with Dollens Electric—they helped us replace old wiring, install new outlets, and install bathroom fans in our home (including adding the vents through the roof). They were very personable and easy to talk to, and it was easy to see that they put a lot of care into their work. We're looking forward to working with them again soon!
The work was completed as contracted. They were very professional nice.
They are simply the best. Polite, on time, communicative, and always ready to help with even mundane concerns. I’ll never use another electrician. Jason and his team are the gold standard.
Response from the owner: Thank you so much James. It is always a pleasure.
Dollens Electric has helped me on several occasions. I highly recommend them.
Response from the owner: It was good to see you again! You are very nice and easy to work for. I hope you get to see those grandkids soon!
Installed a whole house fan that is quiet and effective. Greatly reduces A/C cost. Workers are fast and efficient and cleaned up 100%. Quality products.
This is the second time we've used Dollens, first being when they upgraded the wiring to the entire house. This time they installed an isolated circuit in our garage and some can lighting. Even though it was a smaller job, they treated it just as importantly as the bigger job.They answered all our questions, let us know and talk through our options and didn't do any additional work without letting us know and approve the price difference for our requests, rather than telling us at the end of the job.A+ work!
Response from the owner: Thanks Mathew. You and your wife were great to work for. I still want to steal your dog!
We had a ceiling fixture out. Jason came on out and diagnosed the problem and got it repaired very promptly. Courteous and friendly.
Response from the owner: Thanks Lynne! It was a pleasure to met you!
Response from the owner: Deepak! Thanks for the review. I got to say you held your cool. It is mid December and we had to replace a major costly piece of your electrical system right before Christmas! Because you were so level headed you made it a pleasure to work for you. Thanks and Happy Hollidays!
Response from the owner: It was a pleasure working for you, Thanks for the review! Josh and Elijah mentioned how smart and energetic your son is almost every time they came back to the shop!
Professional, on time service. High quality work. Definitely will use again.
Response from the owner: Thank you Khanh, I am glad we have such great customers to work with.
Excellent. Whenever I again need electrical assistance Dollens is the one I'll call.
Response from the owner: Thank you Lynn.
Response from the owner: Thank you Denise. It is always a pleasure to work with you.
Update 9/2020 - Upgraded some thermostat wiring for me with a difficult routing. Professional and quick.Update - Jason and Josh again came through for me. In the midst of a heat wave, they were able to come to the other end of the county and fix an electrical problem at my mother's house. Got the outlets for the portable AC and lift chair back working and made the wiring safer to boot.Original - Could not ask for better. Jason installed a new 40 amp circuit and an EVo charger for our car. (No more slow 110 charging. Yeah!) While working in our breaker panel he noted a dangerous situation left by a previous contractor who upgraded our air conditioning.(Side note kind of disappointing the inspector didn't notice that the other contractor put in a bigger breaker on a wire that was too small. Luckily the wire insulation had just started to bubble and it didn't catch fire.)Within a week they were able to fit us in to replace the faulty circuit as well as rewire our garage lighting to eliminate some creative but scary runs of extension cords and re-purposed outlets. Now I have bright lights and when I look up, I don't see wires draped everywhere.We connected with Jason of Dollens Electric through our equally excellent general contractor Dan Mackey. (Who by the way had nothing to do with the faulty circuit or the creative garage lighting.)Lastly a thank you to Jason's son Josh who got to do the crawling under the house.
Response from the owner: We could not ask for better customers. We are looking forward to their next project!!!Thanks Maggie and Jim!!!
Response from the owner: Thank you Dana, we appreciate you and your feed back.
I've had a few projects done by Dollens..would highly recommend them...very trustworthy & professional
Response from the owner: Thanks Cyndie! Call us anytime, you're a great customer! I hope you and your Neighbor Dave's Work we completed last you two a long time! Good Job with the lights BTW.
Jason always does a great job, thanks
Response from the owner: Thank you Lindsay. It’s always great to see you.
I had Dollens come out to bid on installing a standby generator and they were friendly, on time, and professional. They walked me through options, explained what they were looking out and why and asked lots of follow up questions to make sure i was getting a bid for everything i wanted and needed.
These guys are the best. Very knowledgeable when troubleshooting old problems from less capable electricians who were here for prior owners. Installed a new outlet in my hardwood floor that looks beautiful along with solving our "where to put the lamp" problem. Lastly wired up a cat6 network allowing us to move our router/hub into a closet off my desk.Call/use them; you won't be sorry.
On time, explains the work so you will understand what was done and why.
Jason, Josh, and Elijah were prompt, considerate, professional, trustworthy, and kind. The work for our recessed lighting project was done quickly and with care, precision, and high quality. Jason was very thorough in explaining what they had done and why. I would have no reservations with them and highly recommend them!
This company is great. They were always on time and great at communicating both time estimates and costs. They are very thorough, knew current codes inside...

Understanding Backup Generator Basics

There are two main types of backup generators: portable and standby.

Portable generators are smaller and more affordable but require manual operation and refueling.
Standby generators, also known as whole home generators, are larger and more powerful. They automatically kick in when the power goes out, providing a seamless power supply. A backup generator is a standalone device that provides power when your regular power source fails.

Generators come in different sizes and types. The size refers to the power output, measured in watts. Choosing the right backup generator size is essential, as it ensures that the generator can handle your home’s power needs during an outage.
However, choosing the right size is more complex than it sounds and requires a clear understanding of your home’s power requirements.

How to Calculate Your Power Needs:

To calculate your home’s power needs, list all the appliances and electronics you want to power during an outage. It is important to focus on the essentials that ensure comfort and safety rather than trying to power everything. Next, find out the wattage of each item, which is usually listed on the appliance or in the user manual. Then, add up the total wattage to estimate the minimum power output your generator should have.

Listing Essential Appliances and Electronics

1. Essential Appliances:
– Refrigerator
– Heating system
– Lights

2. Essential Electronics:
– Computer
– Television
– Phone chargers

3. Medical Equipment (if applicable):
– Oxygen concentrators
– Home dialysis machines

4. Additional Comfort Items:
– Coffee maker
– Extra power outlets for miscellaneous use

Understanding Starting vs. Running Watts

Every appliance has two wattage ratings: starting watts and running watts. Understanding the difference is crucial when choosing a generator.

Starting or surge watts are the extra power needed to start motor-driven products, such as refrigerators or air conditioners.

Running or rated watts are the continuous power needed to keep the appliance running. They are usually lower than the starting watts.

When calculating your power needs, consider both starting and running watts. Your system should be able to handle your appliances’ highest total starting watts.

Size Does Matter

When selecting a backup generator size, choosing the right one is crucial. One that is too small may not be able to power all of your essential appliances. On the other hand, one that is too large can lead to unnecessary fuel consumption and may damage the generator. Therefore, it’s important to understand your home’s power needs in order to select the appropriate size.

It's not just about power needs.

There are a few key things to consider to ensure you make the best choice.

First off, think about the type of fuel the generator uses. Whether it’s natural gas, propane, or diesel, each has its own advantages and drawbacks. This can impact the size you’ll need.

Location is also important. Your generator should be placed in an easily accessible spot for maintenance and should be protected from potential hazards like flooding.

Fuel Type and Noise Level

Noise is another crucial factor to think about. Generators can be noisy, so it’s important to consider your neighbors and local noise regulations. Keep in mind that the type of fuel can also impact noise levels, with natural gas and propane generators generally being quieter than diesel ones.

Lastly, don’t forget that the location can affect its noise level. Placing it too close to your home might make the noise more noticeable, while putting it too far away can make maintenance and fuel delivery a hassle.

Considering a sound-attenuating enclosure might be a good idea to reduce noise, but be sure to keep ventilation in mind to prevent overheating.

Local Codes and Environmental Considerations

Before installation, check your local codes. Some areas have strict generator sizes, noise levels, and placement regulations.
Environmental considerations are also important. Diesel generators, for example, emit more greenhouse gases than natural gas or propane generators.
Finally, consider the impact of your generator on local wildlife. Loud noises can disturb animals, and exhaust fumes can harm plants and insects. Choose one that minimizes these impacts as much as possible.

Generator Installation Process

When installing a backup generator, it’s important to ensure that it complements your home’s architectural style. You can preserve your home’s aesthetic appeal while also guaranteeing its practicality.
Take into account the visual impact of the generator placement. Choosing a location where the generator is inconspicuous is essential.
Prioritize safety and adherence to regulations. The generator should be installed in a way that meets all local building codes and regulations.

Tips for Generator Placement

The installation process begins with a site assessment. This helps determine the best location for your generator. Next, is installation and connection to your home’s electrical system. A transfer switch is also installed to switch between utility and generator power safely.

The placement of your generator can impact your home’s curb appeal. Choose a discreet yet accessible location.

Consider concealing it with landscaping or a generator enclosure. This can help maintain your home’s aesthetic appeal.

Ensuring Safety and Compliance

Safety should be a top priority when installing a backup generator. To prevent overheating, it should be placed in a well-ventilated area.

Compliance with local codes and regulations is also crucial. This ensures your generator installation is legal and safe.

Maintenance and Longevity of Your Backup Generator

A backup generator is a long-term investment. Proper maintenance ensures its longevity and reliability.
Regular maintenance can prevent unexpected breakdowns. It also ensures your back up power operates efficiently when needed.
Understanding the fuel consumption rates is also important. This helps in planning for fuel storage and safety.
Lastly, consider the noise level ratings. This ensures compliance with local noise regulations.

Regular Maintenance Schedule

It’s important to remember to keep up with regular maintenance for your generator. This includes checking the oil, filters, and battery consistently. Doing so can ensure that your generator is in optimal working condition, which is crucial, especially during times of need.

In addition to these regular checks, it’s also worth considering professional maintenance from Dollens Electric. They offer generator maintenance plans that provide comprehensive service to ensure all components are in top condition. This proactive approach can help prevent potential issues and extend the lifespan of your generator, providing you with peace of mind and reliable backup power when you need it most.
