"I used A-Star last summer. It went very well. From the salesman to the installers, everyone was very professional, very accommodating, and very punctual. The installation was done in the end of August 2014. When I initially contacted them, summer was just around the corner. As you can imagine, they were booked solid for installations through almost the end of summer, however, they loaned me 4 or 5 (I don't remember exactly) brand new window units to put throughout my house until they could complete the installation, and at no additional cost. I was very pleased with their service. Recently, an issue arose with the thermostat that affected our ability to use the Central Air. They came as soon as I called and serviced it at no charge being as that it had been installed less than a year ago. They offer service plans in connection with the manufacturers warranty, and they were significantly cheaper price wise than all the local competitors. I will continue to utilize their company and service, as well as highly recommend them to others.

Generator Install FAQs, 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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

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.
