"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!!!!!!!!"

Horizon Services is the region’s largest and most well respected plumbing, heating and air conditioning company, with nearly 600 employees serving tens of thousands of homeowners throughout Delaware, Southeastern Pennsylvania, Southern New Jersey, and Northeastern Maryland. After a quarter of a century in business, Horizon Services remains fully committed to setting the industry standard for customer service, installation, and focusing on things that are important to busy homeowners: respect for their time, their home and their property; up-front pricing, and an unconditional 100% money back guarantee. Horizon Services is the Heating Company Your Friends and Neighbors Call to Keep Warm All Winter Long!

"I wouldn’t be writing this Review if one thing would have happened, TALK TO ME. Don’t place the answering service in the position of telling a Customer that the Supervisor has left for the day at 2.45p on a Thursday. Especially when the Horizon repairman had just fried our whole cooling system, including the thermostat!! What started with a bad fan motor in a new AC system that was only 3.5 years old in a $10,000 system, for which we had waited 4 days for the new motor to be installed. Add to that the fact that the repairman told me he would be at our home at 8.30a and didn’t arrive until 11.30a - after having to use a vacation day to wait at home for them to arrive. Then telling me this will be ‘quick’ all I have to do is switch out the motor by mounting it and plugging in the new one. Hours went by, nothing. He comes in to test the thermostat and it is non-responsive. He tells me to get new batteries, which I did. Then asks me, “these are new?” To which I say, ‘of course’ - you watched me take them out of the box. Then he goes out to his truck for the next 1.5hrs, supposedly speaks with his Supervisor and comes in and tells me that he has fried the system. I reply by saying I will be calling a senior person to speak with them. Called 4 times and never spoke with anyone. Each time I waited on hold for an extended period of time. Each time, I was then told by the answering service that someone would call and never did. Then at 2.45p I am told “everyone has left for the day” and no one would be calling. This was a Thursday, I had been home all day and no one would speak with me. We remain without an AC system, no plan, no calls - - nothing!!! If I could rate them a ZERO, I would,"

"I had a federal pacific panel replaced. The technician and work were professional. However, I explained to the technician that I lost power in a large section of wall. After the job was complete, I found I still didn’t have power in the wall. Now I’m being told it is a separate job and cost. An explanation before having the work done about it being a separate problem and needing additional work would have been very helpful. All I’m told now is they can come out for a service call which is $212 plus whatever the issue is. This was a miscommunication error on Mr. Electrics side. I informed the tech about the problem and there was no testing on the wall afterwards. Very disappointed."

Electrical questions, answered by experts

While the line can't be removed, a pro can place a cap on the end to stop leaks. Contact a pro for a service call and speak with them about the related costs of either capping or removing the line altogether. Capping a gas line will cost between $75 and $150 while removing it will start at $250.

Different fences use different amounts of electricity, but their operating costs are very low overall. Electric fences pull between 4 and 25 watts from the system if you have an average-sized yard. Barring any complicated math, you can expect an average electric fence to cost less than $5 a month to run. Aboveground electric fences, which are not typical for residential use or small animals, can cost more, but you shouldn't notice a significant change in your electric bill. 

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

The cost of fixing faulty wiring depends on the type of repair required. Replacing an electrical service line, for example, can cost up to $500. Rewiring an entire house will cost at least several thousand dollars. Replacing old wiring like knob and tube wiring will be even more expensive, but fortunately that kind of outdated wiring is fairly rare. Always get an estimate from a reliable electrician to learn the cost details.
