"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!!!!!!!!"

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!"

"After inspecting the problem, the service man roamed around my house telling me all the things that needed to be fixed. He then showed me the tank was loose and tightened 2 bolts and caulked around the bottom. This visit wound up costing over $400, and could have been done in a matter of minutes. It took 4 phone calls to get a small refund, and cancelled contract."

"Juan did an outstanding job and was every bit of professional.

Generator Install questions, answered by experts

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. 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’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.

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

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.

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
