"We had an attic fan that stopped working. The tech who came out explained everything he was doing and testing before actually doing it. We thought we would have to replace the motor, and he was honest about the cost upfront. Luckily it just happened to be a faulty switch. He saved us hundreds of dollars!"

"When my mother's health took an unfortunate turn for the worse in the last year due to developing medical issues, the family and I struggled to solve the problem with a bit of DIY trial and error - but quickly realized we were in over our heads! Thankfully, Clark Handyman Services picked up and were happy to help listen and coordinate with me personally to guarantee that our needs were met without fail and assured us that they would be able to meet our goals and have everything accomplished well within the estimated window of completion. The all-weather handicap accessible ramp with attached deck and rails (all treated lumber which was sealed and stained perfectly to match the existing structure) sit neatly in place. It is squared to a "T", stable enough the grandkids can run around without wobbles, and to top it off it all fits snugly against the house without water run off inevitably causing me future worry by penetrating the foundation and basement walls thanks to the gutters and drain spouts they installed before wrapping up the project! THANK YOU for bringing us peace of mind with our mother's mobility, for being safety oriented, kind, courteous, and patient group of professionals who are dedicated to pushing the boundaries for the standard of excellence just a few steps further than I thought possible. Will be using them again this summer and telling my friends! -JB & Family"

Generator Install questions, answered by experts

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.

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.
