Q: How much does it cost to install a whole-house generator?

To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don&rsquo;t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.</p></div>

Q: What happens with the generator when the local power goes back on?

• <div><p>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&rsquo;ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.</p></div>

Q: Can you use biofuel in a whole-house generator?

• <div><p>In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.</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...
