"Skip Ward came to my house to reroute my heating system so that I could remove the old heater in the bathroom. He arrived on time and was very professional and curteous. He knew exactly how to accomplish what needed to be done. Within no time my heat was back up and running. I would highly reccomend Ward Plumbing to anyone who needs the job done right."

"Outstandingly! The installer from Orbit, a young man name JOHN did an outstanding job of installing, providing helpful information, and providing and extra service which required repair of a leak in the main water line coming into the house. Great job of coordinating with the American Water Company worker to manage water shut-off and turn-on. I can't thank Orbit enough for sending JOHN to install my system. Anyone receiving his services in the future is in for a treat. John deserves a "Beyond the Zone" (Military personnel will understand that terminology) pay raise he is well worth retaining as a skilled technician and one H***-of-a-nice person, a great public relations entity for ORBIT!"

"Paul and associates did a terrific job. The installation went very well. The unit used was not the typical unit because our house I'd so large. Paul utilized a hot water distributor from our old hot water heater. We now have instant hot water all over the house.
I will use Surfside in the future!

"James showed up on time and got promptly to business. He checked out our hot water heater and flushed it. He then performed a walk through checking out our faucets and bathrooms for any water flow or pressure issues. James discovered that two of our baths had child proofing hardware that was preventing the water temperature from getting hot enough. He stayed and fixed the problem that had been confounding us for years. We would definitely re-hire for future plumbing needs."

"I specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."
