Recommended Customer Reviews

Finally! Someone who knows what they're doing and takes the time to educate/explain, that is, if you're like me and would like to know what's going on. We had a horrible experience with a different company who installed our Navien tankless water heater. I didn't even know things were still not right until we had Keith come for a service/cleaning of our unit. He was able to see that a few things were not set up quite right on the dashboard and physically...he fixed it. Now one bathtub finally gets full hot water that never did. We've been suffering for 3 years! He is really kind, smart, professional and clearly an expert on Navien systems. He took the time to check a few extra things out for me, about flow as well. Bonus, Keith is super responsive to his phone calls and good about keeping his schedule or keeping you posted. I really appreciate his service style. Highly recommend. Cheers.

This company lives up to its name.
When you have a broken water heater over a holiday weekend, calling someone to come out immediately is impossible. Enter ASAP, who was able to come out the next afternoon and install a new one for cheaper than the businesses that we called that were not available to come out for the next few days.
The water is hot again and if anything changes (they came out on Monday and it's now Friday), I will update this review.

Keith installed my water heater two years ago! Delighted with the quick response and incredibly efficient tankless water heater so far. Today, very happy he fit me in when I called to say my water heater was completely turned off. He was able to quickly reset it in less than one minute by pushing the reset button on the outlet. I thought I had pushed it this morning, but he showed me that I hadn't pushed it hard enough and that I can confirm it's reset when the green light on the outlet is lit. If your water heater stops working, especially in the torrential rains we've been having, use a screwdriver to firmly push the reset button on the outlet so you can save the $50 service call if Keith comes to do it.

We've used this company three different times all emergency calls and they showed up on time and got the job done! No need for a long review cause they got the job done!!!

Keith just fixed my hot water leaking issue in the crawl space! I called him yesterday and he was able to come the next day to give me an estimate. He was nice enough to also call me several hours before our appointment to let me know he was running late from another job. He arrived with another person (Peter) and went under the crawl space and was able to determine the leak was from a pipe in the crawl space (versus in the wall) and gave me an estimate right away. I think the estimate was reasonable given the kind of work. I authorized him to go ahead with the work and he immediately went ahead to fix the issue quickly and professionally and also explained to me very clearly the cause of the issue.

We called Keith to flush out our tankless water heater, since we noticed some inefficiency with hot water throughout the house. He surpassed our expectations. We noticed an immediate difference afterward: the hot water is reaching various parts out house more quickly. Keith went beyond the scope of the job, explaining other things in response to some questions we had about some vibration in our shower head. He showed up promptly for the appointment (even a bit early, which was great) and left with everything addressed. Excellent business; we'll be calling him again for future plumbing issues.

Keith knows everything there is to know about Navien Tankless Water heaters. He was the only one who seemed to really know much about repairs. Most Plumbers seem to only know how to install new ones. Keith has a Navien Certification. I in fact, got his name from Navien's list of Certified Repair People.
He came out quickly, fixed the problem with had and his price was very reasonable. Today, five years later my Navien set a Code and he told me how to fix it over the phone, free of charge. Really great guy and not as greedy as most contractors seem to be these days. I highly recommend you support his business. I know I will!

Keith is fantastic! He is prompt, courteous, and professional. A few days ago, our water heater suddenly stopped providing hot water. The pilot would not stay on even after I tried re-lighting it so I called Keith. He came over the next morning and informed us that he could fix it for a very reasonable price. He didn't try to sell us on a bigger repair or replacement. He was very honest with his assessment. The only comment Keith made was that our water heater was very old and may need replacing in the future.
Having done my research beforehand, I knew Keith was right in that the water heater was very old and due for a replacement. We inquired the cost of replacing as well as recommended brands and Keith walked us through all of it. He broke down the pros and cons of various brands and gave us a very reasonable price. We agreed to do it and Keith was able to squeeze us into his schedule the very next day. He came by with his guy and they installed the new water heater and hauled away our old one. We're now up and running with hot water thanks to Keith!
If you need help, I highly recommend him as he is a licensed plumber, professional, courteous, and more importantly a candid person who will treat you fairly.

Had issues on my tankless and the manufacturer asked me to contact a few of the licensed plumbers. Called & left messages for several local places. These are the only guys who returned the call. When I described the problem, he gave me a solution. That's it. None of the ""I have to come & see what the problem is"" BS or other nonsense. I think I found a good plumber! Keep up the great work

Today Kei came out to repair my water heater. He did a great job. He was hear on time and charged what he said he was going to charge. I'm very satisfied and would highly recommend him.
