We've been without hot water for two weeks (and counting)...in sub-freezing temperatures because of…read morecompany-wide incompetence. Our tankless water heater stopped working on a Friday afternoon and flashed a code. We contacted WMH because we have a service contract with them for the entire house. They wouldn't send anyone out until the following afternoon. The technician identified additional parts that were needed to complete the repair and ordered them from the manufacturer to be delivered directly to our house ASAP to avoid hassles with their warehouse (very appreciated). The problem is that he failed to order the parts related to the initial code that prompted the service call in the first place. We were out of town (thankfully) for several days and when we returned on a Saturday, the part was waiting for us at home. We called WMH first thing on Sunday, and the wouldn't send anyone until the following day. At this point, we'd been without a water heater/hot water for 10 days. In literal freezing temperatures that prevented snow from melting for weeks. No sense of urgency on their end whatsoever. By noon on Monday, no one had come to the house or called. We called to get a status update and were told that the technician didn't find the part in the warehouse, so he didn't come to the house. No one called to tell us this. If they had, we could have told them that WE HAVE THE PART AT THE HOUSE! They send he would come out later that afternoon to make the repair. Then they called back after an hour to say, never mind, the job takes too long so they won't send anyone until the next day (Tuesday). It's Tuesday (12 days without hot water), and the technician finally appears in the morning. After working for four hours and installing the new part, he tells us that the prior tech failed to order the parts needed to correct the flashing code (i.e., the reason we called them in the first place). They had to order the part, wait for it to come in, and then schedule another service appointment. We asked that it be sent directly to our house so we could keep track of it and use another service provider if we wanted. He agreed. By Thursday (our 14th day without hot water), we had to call WMH to ask when we could expect delivery of the part because it hadn't shown up yet. They confirmed it had been ordered but would get back to us with an ETA. They never got back to us. Friday morning, (15th day without hot water) we called WMH to get an ETA on the part. They said it had been shipped directly to their warehouse (contrary to our wishes) and that they'd be sending someone to make the repair that afternoon. We're still waiting for that technician to show. In the meantime, we saw an Oliver van pull into our neighbors' driveway and promptly setup a maintenance contract with them and will be using them to finish this job if WMH is yet another no-show. Maintenance contract: We have a service contract with WMH for several years and not once have they showed up on the scheduled service date. Nor have they called us to let us know they weren't showing. So we miss work that day and then have to miss work another day for when they actually do decide to show up--but they only show up if you micromanage them. And we do not have time for that, especially when their customer service is abysmal and their services are objectively over-priced!!!

My plumber recommended them to restore my hydronic system when a prior contractor couldn't restore…read moremy system after shutting it down for plumbing work. Basically, an entire zone wasn't getting any heat and the pump was running hot. Karalis' guy charged me a $135 diagnostic fee to tell me that either the system was air bound, or the pump was bad. I could've diagnosed that myself. He promised to get me an estimate on making changes to the system so that the problem would be resolved. After a few few weeks of not hearing from them, I called and got the owner on the phone. He said that they were looking into it and that they would get back to me with an estimate for the work. It is now been three months. Radio silence. I'm not impressed, I won't use them, and I recommend you don't either.

We recently had a compressor go down for a large walk in cooler and these guys stepped up with a no nonsense quote. They had us up and running in a couple of days. They were very professional. The owner took the time to go over the parts/repairs needed and answer all of my questions. The price was fair. Moving forward they also recommended a preventive maintenance service to keep the new compressor and other parts of the unit healthy and running strong. I can't speak for their AC and heating (yet!), but for refrigeration needs in the Delco area they are reliable and responsive. Thanks again guys!

The first company was incapable of resolving the problem. I tried DZO. Within a few days two men arrived and fixed the problem in 30 minutes. We discussed a second issue and made a future appointment for resolve as they needed additional materials. Second issue solved. I canceled with my previous company. Today they did a regular bi-annual maintenance call. Some additional cleaning was done, however, I had been told about this at the last visit. We set a date for the fall. The prices are comparable to my prior company. DZO is responsive, professional and competent. I'm glad I gave them a try. Their performance exceeded my expectations!

Owner did new home install years ago. When we questioned The btu's on the units he installed, he…read morelooked us in the eye and said that if it wasn't working properly he promised to come back and install a larger unit. Of course, once summer hit and we knew we needed the bigger unit, we called him and he basically told my husband to F off. Also, we later realized that he put a high-efficiency gas furnace in our attic which is non-conditioned space. Wrong! Condensate line would freeze up and trip the system constantly. Once again, when we inquired about it with him he told us to F off. We've had numerous other professionals tell us that the ductwork system in the attic and in the basement basically makes no sense whatsoever. The owners incompetence and lack of professional knowledge is only preceded by the fact that he it's just a total butt head, and his word and handshake mean nothing.

He reiterated that we didn't need to change out our current equipment but if we feel it's important for environmental reasons there are good options.

On the first cold day this winter he claims the heater is all rusted out in the exchanger and has to be replaced, along with the entire system because a new heater can't work with an old air conditioner. Our neighbor suggested we call their guy. He's been in business for 30 years. Needless to say, the heater was not rusted he showed me the unit was very dirty, the fan motor and wheel were clogged with dirt and there were two dead birds in the chimney. The outside air conditioner was only 10 years old. I'm convinced SK had never done anything other than collect their fee and try to sell stuff we didn't want or need.
