"John and his team were excellent. Of the electricians I got quotes from, John was the only one who noticed that some existing breakers in my panel didn’t match the panel’s manufacturer and shouldn’t have been there. His team arrived on time, was thorough, and focused on solving the problem I brought them, with no upselling or scare tactics. On top of that, the price for my EV charger install was excellent. Highly recommend, and would work with again in a heartbeat."

"Wow, they just left and I am so beyond impressed with everything, from start to finish. Adam helped with our estimate and was a pleasure to work with. He came next day for our estimate and from there, went above and beyond to answer every single question and concern of mine, he was fair in his pricing, very timely in his responses and even remembered the layout of our home when I called a month later. They were even able to schedule the job next day due to the inclement weather. Jim and Matt arrived early and were so courteous and pleasant to work with (they were even extremely considerate of my infant's nap schedule). We had them install two new outlets for ac's and electronics and they had to snake the wires in impossible places. Jim listened to every single one of my concerns and came up with excellent solutions and they left everything in better condition than they found it. When I asked if there was another way to get the job done, he listened and offered to change his plan. It was so nice having a contractor actually listen to you and work with you. I will definitely be hiring them again - I am so glad I finally found an electrician that is respectful of an older home. Thank you Adam, Jim & Matt! You guys rock!"

"I've used J&A's services on two separate occasions: once around six years ago, and then again approximately two years ago. In both instances, I found them to be exceptionally professional and highly knowledgeable. The first project involved them replacing the electrical panel and service in my home shortly after I purchased it. More recently, their task was to install all the wiring for an upstairs project I was undertaking. They exceeded expectations in both encounters."

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 FAQs, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

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.
