Customers say: True professional

"Armando removed dysfunctional glass shower doors and patched up screw holes; remounted a lose shelf in the shower; reset a closet louver door after adjusting the track; replaced damaged baseboards and painted afterwards; patched a crack in a wall beneath a bay window; and installed a screen door. I am very happy with the outcome of everything. If you are looking for quality work and fair pricing hire Armando. I'm so glad I did. I'll keep his business phone number handy for any future repair, removal, and installation needs I may have."

"Did a great job, even corrected some code violations that were present when we moved in. Installed multiple 110v, 230v single phase, 230v 3 phase and 480v 3phase circuits, wired a paint booth, Tumbler unit, overhead crane systems, and even did some repairs on a complicated piece of machinery that wasn’t working. Great guys work hard no excuses. They get the job done plain and simple. I had used them twice because they were that reliable."

Generator Install FAQs, answered by experts

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

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.

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.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
