"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

Proudly servicing commercial and residential customers in the West Chester and the surrounding areas for 25+ years. We take great pride in the quality of our work, our professionalism and customer satisfaction. For fast, reliable, and efficient service give us a call today. You will not be disappointed.

"I moved my business to a new location and needed a company to wire my new office for internet. Penn Security called me within minutes of me submitting my request to Home Advisors. Although they could not do the work for wiring my whole office that day, they did come to give me a quote and to make sure that I had at least some sort of internet access. I cannot conduct business without internet. I thought that was so incredibly thoughtful and amazing of them. They did the work 2 days later and did a wonderful job. The crew was friendly, courteous and efficient. I have had no problems with the installation they performed and I would recommend them to anyone! Truly an amazing company!"

I am filing a complaint with the Attorney General's Office and contacting 6ABC consumer help. Might even get my niece involved at this point.

Generator Install questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
