"WARNING- do not use this company, didn’t do the job agreed and paid for and don’t guarantee work!!!! I had a simple GFCI outlet installation required for a tankless hot water heater in our basement. They came out for an estimate, we agreed on where the source circuit would be to run wire to the new outlet and they took pictures and wrote details of the job. Electrician came out to do the job and I plugged the hot water heater in and it seemed to be ok and paid the bill. However, after the electrician left, we notice the hot water heater stops producing hot water after a few minutes or doesn’t turn on every time. Suspecting there may be an issue with the hot water heater, I called the plumber who installed the hot water heater and everything seems fine with the heater and new outlet from their diagnosis and they can’t determine the issue. I then did some diagnostics myself and noticed the electrician didn’t use the agreed power source I paid for to run wire to the new outlet, he used a different much closer source from a light fixture box, saving him on wire cost and labor time. Suspecting the issue may be a faulty GFCI outlet or something on the circuit, I called the electrician to tell them the situation and they agreed to come out after some haggling to investigate but said I’d need to pay their min $120 fee for the visit if the issue is unrelated to their work. The electrician came out and replaced the GFCI outlet and after testing the hot water heater, the same issue happened with hot water not coming out. With the issue now appearing to be something on the circuit that’s affecting the sensitivity of the GFCI outlet, I asked the electrician to run the circuit from the original source agreed and I paid for. I was told he can’t do that and needs to talk to his boss and asked me to pay for the visit. I refused to pay telling him they haven’t installed the circuit as agreed and I paid for. He agreed and said someone will get back to me to run the circuit from the original agreed source. After a couple of weeks I get a call asking if I’d pay $120 to run the wire from the original source circuit I already paid for. I said I wouldn’t and they should honor the original agreement. The person said he’d talk to his boss. After 3 weeks of hearing nothing, I got fed up and ran a wire myself from the original circuit source to the GFCI outlet. I plugged in the hot water heater and it worked perfectly, confirming the issue was something on the circuit the electrician chose to run the wire from. All I asked for was to do the job we agreed and I paid for and everything would have been fine. They tried to nickel and dime me to pay more to redo their work which wasn’t what we agreed and I paid for. STAY AWAY FROM THIS COMPANY!!!"

"The experience was not quite what I expected. I had clearly explained the scope—replacing 10-12 standard switches with smart switches giving model number/spec—and was hoping for a lump sum proposal, but they only offered hourly rates, which is understandable. They estimated it would take about 2 hours, but the job ended up taking over 4. While they mentioned having done similar installations before, they spent quite a bit of time reviewing instructions on site, which added to the time and cost. The final bill was over $800 for a couple switches, including a service fee and $10 for wire connector? (The switches come with connector) Just a heads-up to others: be sure to ask detailed questions about hourly charges and how time will be managed, especially for smart device installations."

"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

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.
"Kenny from Horizon was very professional and a great guy. I appreciated his insight. He was just doing his job. He was very pleasant. However, I was disappointed in a tune up amounting to just a check of voltage on my motor and capacitors. I thought there would be cleaning involved and an adding of a pound of freon to my unit as advertised. That didn't happen. I received an estimate of over $700 for the replacement of 3 capacitors. I could replace all 3 for under $50. To charge $650 labor is raping the customer. Then the blower motor (that is NOT multispeed) was estimated at about $1100 replacement. The motor costs $210. So again...I feel raped. For a charge of almost$900 for labor. Unbelievable! I've lost my trust in companies that are so money hungry that they lose sight of reasonable business. I will now change out my own parts as I have no confidence of reasonable pricing. Maybe people can afford to be overcharged about $1100. I can't and I won't if I can help it. Next time I'll use my own voltage meter and check my motor voltage and resistance on my capisiters myself. They should be paying me for their so called "tune-ups" as they are only a ploy to pressure you to buy a new furnace/AC system. Ohh and they won't install a new furnace to an old AC unit and Visa versa. That's what the guy told me. Are you kidding me? He told me it would cost$11,000-17,000 for a new system. My father in law just replaced both for $9,000.... So again a minimum of $2,000 overcharge. Nope, Horizon, your scam won't work with me. I'll be glad to tell everyone I meet and show them your ridiculous estimates!"

Generator installations FAQs
Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:
Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000
When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.
When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:
Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts
Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
Here’s what you can run with different wattages and types of generators:
Portable generator:
2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.
Partial to whole-house generator:
20,000 watts and above will make it seem like your home’s power is still on.
The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:
Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
