"I'm attaching an update here as they came back out and did pay for the work the previous electrician did. In addition, they also replaced our panel as they updated it about 3-4 years ago before surge protection was part of the standard build. We haven't been billed yet but I thought I should be fair since they did come out and remedied the shoddy work that was done initially. Hopefully there are no more issues going forward"

"Both electricians/contractors were very professional and friendly. I showed them the room (aka a nursery with a vaulted ceiling) as well as the ceiling light replacement, and they immediately got to work. They finished in less than 30 minutes instead of the 1 hour I was told over the phone. They were honest and charged for half-hour."

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

We charge flat rate prices for all services so there's no hidden fees for you!

"Tyler did a fantastic job for us. He assessed the problem, developed a recommended solution and provided options. On the day of the install, he ran us through the plan and quickly got to work. Friendly and answered all the questions we through at him with a smile. Price was very reasonable and would definitely hire again."

Generator Install questions, answered by experts

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

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.

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. 

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
