"We highly recommend J.P. McCurdy Electrical Services. We hired this exceptional shop to replace all the old knob and tube wiring (along with switching out a number of light fixtures and installing several ceiling fans) in our 120-year-old Victorian home – a challenging job that a couple of other electricians didn’t feel confident undertaking. Owner Jack McCurdy personally came to size up the job and give us a detailed estimate, and his professionalism, courtesy and extensive knowledge sold us. What was originally thought to be a two-week job was finished in six working days as foreman Joe Costain efficiently deployed his crew and brought in a second crew on a few days to expedite the work. Joe was great at communicating what kind of activity we could expect day-to-day, especially as both my wife and I are working from home fulltime during the COVID pandemic. He and the crew checked in frequently on our preferences, minimized the number of holes in the ceilings and walls (including avoiding harming our wallpaper in a couple of rooms altogether), and cleaned up well at the end of every day. Jack’s estimate was competitive and the final accounting accurately included the additions and subtractions we agreed to during the job. We feel so much better that we’ve finally eliminated the risky knob and tube wiring and updated the entire house’s electrical system. McCurdy is a full-service shop that does all kinds of electrical work – if you want a trustworthy and capable electrician, give Jack a call!"

"Jose was great to work with. He was quick to respond, came by on short notice to have a look and provide a quote for the work (Installation of one new smart thermostat and replace one old thermostat with new thermostat; requiring separation of baseboards due to wattage). Very competitive pricing, showed up on time at each appointment and got the work done quickly. He left the place cleaner than before, and walked me through everything after the installation. Can highly recommend Jose for any electrical work!"

"It was a absolute pleasure working with the Wilson Brothers team from sales, site planning and install. The install and electrical teams were very professional and demonstrated in depth knowledge of the product and their craft. They arrived at the time specified and worked very neatly and in an organized fashion. We would absolutely recommend Wilson Brothers for any Heating/AC needs."
Three of the five heads are marked by the numbers in the blue circle. On the inside of the house is where you will find the mounted units. The slim ducts run alongside the white arrows and will eventually be covered to match the exterior of the house.
The slim ducts in the basement ceiling that connect from the branch box all the way to the 5 different heating and cooling units. These will be covered by the ceiling tiles once the job is finished.

Generator Install questions, answered by experts

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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. 

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
