Get matched with top tankless water heater installers in Unionville, PA

"Within 4 days I had a new tankless water heater installed. Adam and Brendan went above and beyond. Thanks!"

"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."

"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."

"Happy with the water heater install"

"Joe was wonderful.  In the morning, we woke up to our hot water heater not working.   He was here in an hour and replaced the hot water heater installed in three hours.   Great experience and wonderful guy. <br />"

"I looked requested quotes from several plumbers to have our water heater replaced with a new tankless water heater. One of the companies just gave a quote for a after having me take photos of the existing water heater, and the quote was for simply a replacement, not what I wanted. Another company came out after several days and said it would be awhile before they could do it because they were so busy. This was two weeks ago. Still no quote. Jon from Delaware Plumbing Professionals was out the morning after the day we called and after looking at what we had, gave us a quote right then. We waited a bit for the other quotes, and decided to go with Delaware Plumbing Professionals. Jon and his apprentice, Nick, were here as scheduled and got the job done. The installation took quite a while, but is very nicely done. They covered the floor and were careful to not make a mess. Now I have lots of hot water. Once the installation was done, Jon showed me where all the shutoff valves and controls for the water heater were. I'm very happy with the job they did. I've used this company before for a faucet replacement on an Angie's List deal and was happy with it as well. It was one reason why I decided to go with them again. I really like that just before they arrive, you get both an email and a text message telling you they are on the way, and both include a photo of the person coming, so you know who to expect and are comfortable letting them in the door. It's just an added safety measure that adds to my satisfaction."

"The workmanship was very professional and cleaned up afterwards. Wouldn't even know they were here. Billy did an excellent job with the removal and instillation of a new hot water heater. Brought the instillation up to code by adding a drip pan and expansion tank. I have them coming back to replace valves for washing machine and installing shutoff valves."

"They were summoned by my Home Warranty Company. The 75 fee is my required co-pay from the warranty co. My hot water heater is 15+ years old. They welded a pipe on the bottom of the leaking heater. Work was done right, it stopped leaking. 2 weeks later they were back for another leak, the relief valve. The hot water needs to be replaced but my warranty co wants it repaired if that is possible, so that's not Clear Water's fault. After the 2nd repair, we probably could have had it authorized for replacement but the "items not covered clause (again not the fault of Clear Water, set by warranty co) would have cost 400 - 500 dollars. The heater is gas powered and we would like to convert it to electric. We have an estimate of 895 for the whole job, and the type of heater we want. I think there charges for the extra items are high. There work and professionalism and punctuality were good but I can get that elsewhere for less. <br />"
