"Cale, Kyle, and crew are superb. They just installed my whole house generator and I can't overstate how personable, knowledgeable, and neat they were. Communication is excellent. I had to wait 5 months to receive my Generac because of a sever nationwide backlog, but Cale kept me informed all along. There is no other electric company I will ever use from now on. Paradise, you rock!"

Customers say: Quality work

"Artique Constructions did an amazing job with my bathroom and kitchen remodeling. Can not recommend enough for their quality of work and commitment to deliver to perfection. I chose very modern high end designs and their work was impeccable. I would have spent more than double if I had gone for anyone else. I got complete remodeling of kitchen(floor/cabinets/island/pantry/installation of all kitchen appliances/backsplash/open shelves/led ceiling lights) bathroom(bathtub/vanity/floor/bath tiles/built-in shelves/toilet), changed all switches and electric boxes, trims throughout the house, paint, door knobs, hinges, custom wall paneling. Garry made the house look like a million bucks houses featured in magazine. He is very trustworthy and patient. His attention to detail is amazing. Would suggest anyone who wants to get their house in amazing shape with no hidden costs Garry is the person to go to."

Generator Install questions, answered by experts

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

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.
