"Highly recommend contacting them for electrical work! Responded quickly to come and give a quote for a generator hook up. Explained everything thoroughly and gave helpful suggestions as this was my first experience getting a generator to power the house. Very reasonable pricing. From first contact to getting it installed in under 2 weeks. Very happy!!"

"Posted a job for a boiler replacement on homeadvisor on thursday and got a call in less than half an hour. Ron, one of the owners, said he could come take a look on saturday morning. I got a quote on monday. I decided to hire them on friday. Jeremy the boiler specialist and other co owner came by the the next day to take a few more pictures and check on a few other things. The boiler we decided on was a special order and took a few weeks to arrive. It came in on a monday and was installed by thursday. They started on thursday morning with a two man crew. Around lunch the Jeremy came by to see how things were going. Around 2pm an other two guys showed up to help. At about 3:30 the co owner and boiler specialist came by to oversee the final part of the install and operational testing. I was originally told it would be a two day install. They didn't just replace the boiler, they replaced the expansion tank, dual zone control box, etc. They worked until around 7pm to get it all done in one day. They bled all the radiators in the house and made sure they were heating properly. They took all the old parts with them and left no trash behind. Everybody from this company was extremely professional. They arrived within five minutes of the time they said they would be at my house. Nobody could beat the quote they gave me for the install. Any questions I had were responded to in 30 minutes or less. The install looks amazing so much shiny copper pipe. Cawiamca gave me a 3 year warranty where they will take care of all the labor and parts if anything goes wrong. This was by far the best experience I have ever had with a company coming to my house to do something.They performed consistently above my expectations. They will be the first people I call if I need any more work done on my heating system. I highly recommend Cawiamca."

Generator Install FAQs, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
