"Both our inside and outside A/C unit was freezing up with ice.  When the ice would thaw, we would get a lot of water in the basement.  We had a different company come out first who told us nothing was wrong.  We then called DiBiase.  Joe came to our house on time as scheduled, found the problem and fixed it.  He was very helpful and got the job done quickly at a reasonable price.  I would definitely recommend them, we will be using them again in the future.

"My initial contact with Mattioni was to simply schedule a winter check-up on the furnace in our new house. I knew the furnace, a/c, and water heater were all about 11 years old and could be in need of replacement. One month later, I’ve had Mattioni replace all three and also perform some smaller plumbing jobs after the annual healthy home plumbing inspection they offer as part of their contract program (which came free for one year after I had the furnace and a/c installed). They’ve done too much work for me to go into detail on every aspect of every job they did, but, on the whole I have been very impressed with Mattioni. Their customer service, quality, and attention to detail seems top notch. If you’re just comparing prices, they’re probably not the cheapest contractor to use, but if you factor in the quality of the service they’re providing, I think their prices are very good, which is why I rated them A in this regard. As with any big jobs like installing a furnace or water heater, small hiccups can occur - in fact, a week after the furnace was installed and I had the plumbing inspection, a small gas leak was detected. After the hot water heater was installed, one of the fittings in the pipe that leads into the water heater leaked a small amount of water and set off the alarm they installed. In my view, small hiccups like this are to be expected when new installations occur. Where Mattioni really shined was in their response to these problems. In particular, I would recognize Jared C., the plumber who did most of our plumbing work. He noticed the small gas leak and had one of the HVAC techs sent out within several hours to address it. He also returned the late the same day he had installed the hot water heater to correct the small leak that had resulted from a defective fitting. I found his attention to detail and willingness to help my wife troubleshoot over the phone and then return late after a long day and fix the small problem to be exemplary customer service. On the whole, I highly recommend Mattioni. If you’re just interested in finding the contractor with the lowest price, Mattioni is probably not going to be your preferred contractor (although they were willing to match lower quotes I received on the hot water heater install). If you’re looking for an HVAC or plumbing company that has responsive and friendly customer service, technicians that pay attention to detail and treat your house as your own, and will ensure that the job is done both correctly and with a high degree of quality, Mattioni seems to be one of the best I’ve used in my years as a homeowner. They will certainly be my go-to plumber and HVAC company for the foreseeable future."

"My hot water heater was replaced the same day. Old hot water heater was installed in 2000 so it didn't owe us anything. Done Right Today was courteous, professional, and offered a reasonable price. My wife and I were very pleased with their work. David and Jan Magaha"

"Workmanship (Billy Pearsall) was excellent and done quickly; very courteous and professional. However based on various options quoted and online prices for the same heater model, it seems that the premium for same-day service and 6 yr warranty on the labor and miscellaneous parts was over $500! If I were to do it over again, I think I could have survived a week without hot water and would have ordered my own heater. As it was, the labor (and overhead?) would calculate out to ca. $300/hr."

"Quick response on a Sunday after my hot water heater failed, with ValDel able to supply the brand of water heater I was looking for. No one likes putting out the kind of money that this type of emergency repair requires, but I was able to negotiate significantly down to almost match a verbal quote that I had received earlier in the day. Jason was an excellent technician, very courteous, and completed the job quickly. I would definitely use ValDel (and Jason) for future needs."

"They are very professional and efficient. They respected my property and did a very good job installing quality water heater. Price charge is fair compared to others. Financing is great, too, with no finance charge if paid in 12 months. I'm very happy with the persons who did the work."

Customers say: Quick response

"I have a maintenance contract. Today Fabian came out. He was very thorough. He spent two hours at my condo performing all kinds of tests. Before he left he went over things I could do to get better performance from my heater. I appreciate the fact that he did not try to pressure me into picking something. He emailed me (while in the truck) options and also explained different ways to pay for it. He noticed the oxygen in my home. My husband had CHF and COPD so I was specifically interested in the ways I can help his breathing better. I believe in todayâ s environment itâ s difficult for companies to get really good employees. This young man , 20, had a great work ethic and a bright future. Very pleased with the service I have received. Thank you Harris."
