"I contracted Level Home Services through Costco for a full A/C and furnace replacement and have been satisfied with their service at every point so far. The initial inspection to get a quote was extremely thorough and informative, and they gave me several options at different price points, all of which beat the other vendors I was looking at. When it was time to actually complete the work, the technicians were prompt, professional, helpful, and courteous. After 2 full days of work, they walked me through everything they did in detail and answered all my questions. By the time they left, the only sign anyone had been here was the shiny new equipment in my basement and yard -- no mess/dirt anywhere (except my own). It was a big job so it was pricey, but definitely money well spent and I would not hesitate to hire them again."

Our service department is set up handle your calls with experienced dispatchers and we back them up with a plumber in the office to answer your technical questions. Hopefully keeping you informed with a way to resolve your emergency or problem. We have a full time parts purchasing manager to locate the hard to get items and keep your job repairs moving as smooth as possible. During daytime hours (Monday - Friday) we will always have someone to talk to or an estimator to help work up a cost for your repair. Our goal is to make the unwanted call to a plumber a good experience. Knowing that most plumbing emergencies are not in the budget, we have a link to a finance company on our web site that has experience in this type of emergency funding and they can help in as little as 10 minutes in most cases. We don't want you to have to call a plumber, but if you do, we want it to be us and to be a good experience for you.

"Had an emergency clog that flooded basement bathroom. Perry came over and we thought he was awesome. He seemed very kind & was happy to help. Got rid of the clog and even fixed our garbage disposal. Forked out a little over $380 but didn’t care because I was relieved things were fixed. Unfortunately Perry didn’t connect the hose back up to our washing machine so when we ran it, our basement flooded even worse. Contacted Perry to see if he had anything to at least help suck the water up and asked if PlumbCrazy covered this sort of thing. He replied and he said “For all I know you moved to clean and left it off.” I promise you we didn’t move anything yet. It definitely wasn’t intentional that it was left off. However, I am very frustrated that something like this can happen and he doesn’t want to take any responsibility for it. Our carpet, my speakers and a few other items were soaked from this incident and now I’m over here wishing I didn’t choose to do business with this company. I hope in the future Perry double checks that he hooked everything back up so no one is left on the situation we are."

"Sobieski did the HVAC/ insulation on my new construction home in 2021. Every summer, there have been condensation issues in the basement bathroom. Multiple technicians have been out and "fixed the issue," but it is still occurring. The last technician quite literally said he watched a YouTube video about exhaust fans while installing a new exhaust fan for us. The company as a whole is incompetent, hard to communicate with, and takes no accountability for their wrongdoings. Absolutely steer clear of them if you want your work done correctly and do not want to waste your money."

Sewer Cleaning questions, answered by experts

Your home has a few telltale signs of a sewer line problem. If you notice multiple plumbing fixtures (toilet, sink, or shower drains) appear to be clogged, call a plumber ASAP. Also, if water appears in the tub or shower when you flush the toilet, you likely have a sewer line issue. A sulfur (rotten eggs) smell and bubbling or gurgling noises at the drain also warrant a check. And keep your eyes peeled for changes to the yard, such as a new indentation or mysteriously soggy grass.

It's advisable to have your sewer line inspected every three to five years to ensure its proper functioning and detect any potential issues early on. However, the frequency of inspections can vary based on factors such as the age of your sewer system, the type of pipes used, and your property's location. If you notice any warning signs like slow drains, foul odors, or sewage backups, it's essential to schedule an inspection promptly, regardless of the regular maintenance schedule. 

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.

It might be possible to dissolve hair caught in a drain, but it’s usually not a good way to go about clearing the clog. Some sources mention that baking soda and vinegar can do the trick, but this won’t actually dissolve the hair. The hydrochloric acid in drain cleaners can dissolve the hair over time, but it will much more quickly destroy your plumbing pipes and leave you with bigger issues. The best way to remove hair is to do it manually with a drain snake or to have a plumber use an auger to pull clogs out.
