"Helpful meets Helpful-Unique Indoor Comfort is now Ace Hardware Home Services, a fourth-generation heating, cooling, plumbing and electrical service company based in King of Prussia, PA. We are a customer service company that happens to excel in heating, air conditioning, plumbing and electrical home services. We have a unique reputation for superior service and quality craftsmanship --- but don't take our word for it --- Experience the Unique service firsthand." Providing HVAC service and repair, system replacement, and air conditioning solutions for older homes. Residential plumbing service, repair, emergency service, and water heaters. Electrical emergency service, repair, home upgrades, generators and EV Chargers.
"Jeff and his team did and excellent job with the installation of two Daikin HVAC units. I had many questions about the units and install and they were quick and thorough in responding. The price and warranty were competitive with high end brands. The crew was courteous and professional during the two day install. They were the only company that included replacement of the coolant lines, rather than just flushing the old ones. So far the Daikin variable speed AC units are exceptionally quiet and the house is very comfortable. Would recommend Ace Home Services and Unique Comfort without reservation."

"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!!!!!!!!"

"though I appreciate the emergency Saturday service call (cost 169.00), I thought the additional charge of 303.00 (450.00) for a diagnostic check and repair ( no parts necessary - just less than a hour of manpower) was a bit exorbitant. perhaps I failed to realize that heating/ac personnel are paid on the equivalent scale as neurosurgeons."

"East Coast comfort did the most horrible thing to us, and they have treated us with utter contempt. We have been with East Coast Comfort since they began when Ed McCollum and Anthony Mongeluzi started the company in 2006. Both Ed and Anthony were to our home in the early years of their business, performing maintenance and repairs, and one of them was here when they installed our current unit. We gave them a favorable review on Angie’s List, and we have never had any complaints about them in almost 20 years, until Lisa Hawthorne. We schedule routing maintenance, so we do not have equipment failures and outages. We have repeatedly been asked by Ms. Hawthorne of East Coast Comfort to reschedule our maintenance appointments, and we have always acquiesced. This occurred again a few weeks ago, and we rescheduled for last week. Ms. Hawthorne again called the day before our scheduled maintenance appointment last week, asked again to change the appointment because of the volume of emergency calls they were receiving, and we agreed as long as Ms. Hawthorne promised we would be given priority scheduling if our system went down. The next day, our air conditioning failed, and I contacted Ms. Hawthorne. A technician came to our home on the afternoon of the next day, but he said parts had to be ordered, and it could be days before they would arrive. I have emails supporting that we requested Ms. Hawthorne to order the needed parts, and she emailed back that the parts would be $1500.00 and labor $500.00. Though we made it clear from our emails that we wanted to get the system repaired as quickly as possible, she did not order the parts and would not grant us priority scheduling. When we learned of this betrayal, we contacted William Henderson Heating, Cooling, Plumbing, and Electrical Services. They worked us into their schedule for same-day service. I have an email exchange that proves how disdainful Ms. Hawthorne was to longtime customers of East Coast Comfort, both of us senior citizens, and one with a cardiac condition. A request we made to Ms. Hawthorne to speak with Mr. McCollum or Mr. Mongeluzi was ignored. In other words, other people had their systems repaired because of our kindness, so we can swelter in the heat and humidity. I consider their behavior toward us to be elder abuse. Good riddance East Coast Comfort, we are now receiving our comfort from William Henderson."

"Ben, the owner, came to our home for a total evaluation of how we might improve comfort and save energy. The focus and area of most concern was the basement, where air leakage was causing some first-floor rooms to feel colder than others. Kyle and John spent roughly seven hours using spray foam at accessible rim joists, lining the walls of the crawl space, and adding insulation to two exterior doors. Since it has been only a week, we don't know if we will see monetary saving, but we are pleased that our first level floors no longer have the cold spots. The guys were pleasant, kept us informed throughout the day, and showed us what had been done before they left. Thank you Home Energy & Comfort!"
