Q: What is the life expectancy of a whole house generator?

• <div><p>Whole-house generators can last<b> 20 to 40 years</b> with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.</p></div>

Q: What’s the normal lifespan of a diesel generator?

• <div><p>You can expect a diesel generator to last for up to <b>30,000 hours of use</b>, 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. </p></div>

Q: Do I need a permit to install a generator?

• <div><p>In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between <b>$50 and $250</b>, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you&mdash;and might be required to do so by your building department&mdash;but you&rsquo;ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.</p></div>

Q: What size whole house generator do I need to run central AC?

• <div><p>To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right <a href="https://www.angi.com/articles/whole-house-generator-sizing.htm">generator size</a>. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.</p></div>

Q: What is a remote start generator?

• <div><p>These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.</p></div>

As a general contractor, i have multiple fencing and railing needs, Rapco never disappoints. They have done all my projects, from wood/vinyl/aluminum fence, to deck and stair rails, even into concrete. I also refer them to all friends and family. They are fast efficient and always cost effective.

While the idea generations were good, you don't actually get firm design plans you can use to then complete a project. That is extra, so it seems to be a bit pricey for what you ultimately do get in the end. Next time I would probably not offer as much prize money knowing this is how it works.

I contacted the swing set man for a quote. He gave me a great quote, but then never got back to me to schedule an installation date. I contacted him via email 2 additional times and have not heard back. I know things come up in life, and overall I am understanding if he is busy, but I do wonder...

The owner, Mark, came originally to give us a quote for a back up whole house generator. He was very nice and gave me his phone number to call with any questions. A few days later, I was trying to unhook my leaky outside hose to prevent it from freezing, but was unable to. I thought to call him!...

Since the installation, I watched my heating and air conditioning bills very closely and they have, in fact gone down in general 30% since last season, even with this extremely hot summer. The capacitor outside did blow out at one point, but they were able to come back and fix it within a day...
