Recommended Customer Reviews

So I had the TOTAL opposite interaction with Norma. I had a water heater go out that I bought from HD. I must say the warranty and customer service of the guys at Rheem was top notch. Anyhow, it turns out that I needed to replace the gas control valve. The guy told me they would ship it out and it will arrive in two business days, and that a local plumbing company will be calling me to setup installation. This was on Thursday evening so that meant the part wouldn't arrive until Monday. On Friday I got a call from Norma and she wanted to setup the appointment for that day. I explained I didn't have the part yet and I won't have it until Monday. So we should set something up for Tuesday. She asked if we had hot water, and I told her no. She said don't worry, you're going to have hot water today. She told me she would check to see if any of her techs had the valve on their truck and within 30 minutes we had an appointment for early afternoon on Friday! She told me when the part arrives just to let her know and they could come pick it up. One other thing, Dillon, the tech who came out and fixed the water heater was nothing but class. Very cool guy and didn't leave until he was sure we were going to have hot water. It turns out not only was the gas control valve faulty but he changed out the thermopile and safety shutoff device. He had a used thermopile that had some juice in it, but he called that part in with Rheem and will re-install it when it arrives. He had the safety shutoff in his truck and replaced that also. Basically it's a new water heater. I must say the whole positive experience started with Norma making sure we had hot water sooner than later. She was awesome to deal with and spoke very good and clear English. And Dillon...not much more to say other than the guy knew what he was doing and am was fun to chat with while he was working. So huge thank you to Norma and Dillon and Collier plumbing.

We called this company to fix our boiler. Jacob, the young guy who came by, was quick and very helpful. Glad to have been serviced by him!

Wow, I have never been humiliated and lied upon by anybody worse than Norma from Collier Plumbing.
Here is the story, a month ago I called them to flush my Rinnai water heater and the guy that they sent did a good job.
So 45 days lapsed, apparently my heat exchanger is now leaking, so I called them again to have them looked at.
The appointment was made the day before and it was for an emergency. I was in the meeting and unable to pick up the call, and they almost missed my appointment time because I was not picking up my call.
It is partly my fault. Jacob came and did the diagnostic with Rinnai tech on the phone confirming that the heat exchanger needs to be replaced.
Fast forward, I called Norma to have the heat exchanger replaced and she quoted me $675. I questioned why? I told her that the parts should be free because it's still under warranty. She told me that Rinnai charged $165 for a change out fee (whatever that is). I trusted her words and asked for a discount, so she gave me $575 instead.
So far so good. Fast forward on Monday. They are supposed to show up at 8am today to fix my water heater; however nobody showed up. So I called Norma asking what's going on? She was talking in the back ground grumpily ""that guy always lazy, he did not show up again?"" (there is a mute button in your phone, FYI)
She got a hold of her plumber, but apparently there was a mishap, a work with the same name with different jobs. But how could that be?
So I asked Norma what would happen? She was flustered and quickly turned rude. She told me to find out what is going on myself to Rinnai. She gave me the order number S000****486 to call Rinnai myself, and I called Rinnai myself to find out.
Then this where all hell broke loose; I was surprised, Rinnai never charge $165 for change out fee when parts are still under warranty and there was no heat exchanger either sent to Collier as they claimed to be. I spoke with Alicia from Rinnai who gave me my case number and part to order.
So at this time, I am angry, confused, and really not knowing what to do. Collier did not even promise to come to fix my water heater. So, I asked Rinnai about another approved Plumber and they gave me another Plumber in the area. I gave him a call and he quoted me $400 for the heat exchanger replacement.
Now, I even more furious because Collier Plumbing wanted to charge me extra $165 non existent fee and slapped it into the bill as labor fee.
Then, Jacob from Collier called and he told me the heat exchanger will be there by 12pm today. WHAT? I just got off the phone with Rinnai representative who told me no parts was sent to anyone.
I called Norma again, and she turned ballistic after I confronted her lies.
I asked her regarding all of the facts I got from Rinnai. She turned violent and asked who was the Rinnai representative I just spoke to. After I gave her the Rinnai representative I just spoke to, and asked her who was the Rinnai representative she spoke to, she balked and turned violent.
She kept saying ""Listen to me!"", but she herself did not want to listen to my concerns. I reminded her that I am her customer, and she shot back ""I am also a customer at other time, not just you!""
I said ""WOW!"" She kept pronouncing my name wrong AND I kept correcting her. Then she asked ""You must be born here, I came from another country you know?""
""What the??? I told her I also came from another country, not an English native speaker, but I will not repeatedly spell my customer's name wrong!""
She hung up after that.
I am glad, I don't have to deal with this company. Rude as hell, no commitment to do the job correctly and BEWARE, they are tagging NON EXISTENT FEE even to your WARRANTIED PARTS.
I opened yelp to write this review and I was so glad that I did not go with them based on yelp review (Why I did not think about that previously? Just go with Rinnai first choice! NOT WISE!!!). After $270 I spent with them, and not a single regards from them for a returning customer... AVOID!!!
And when they want to SCAM their customers, I am glad they are not that smart, they EXPOSED their SCAM to their customer themselves.
And CALLING OUT BASED ON RACE AND LANGUAGE. SHAME ON YOU! Just because you are from other country, there is no rights for you to continuously say the wrong name. THAT'S JUST A BLATANT DISREGARD OF RESPECT, A BULLY.

This review is due to Total Disregard to driving safety. Collier Plumbing truck was hauling major butt in my neighborhood... caught my eye because the driver was driving fast to beat the closing entrance gate... and had to disregard the speed bump placed before the gate.... I tried to call the company 20 minutes before they closed to advise them of this driver/employee but no one answered the phone. I just want to let the owner or fleet manager know how this employee is representing the company, or lack there of.
I will be calling again to talk to someone in this company.

I spoke with Norma over a week ago about the issue we were having with our water heater and she quoted me prices on what the job would cost depending on what the problem turned out to be. She even gave me the number for the manufacturer to see if the appliance was still under warranty (which it wasn't). Now a week later I called her back to see if someone could come back to look at it and a technician arrived a few hours later. He was there for approximately 30 minutes, fixed the problem and we were charged exactly what we were quoted! Would definitely recommend this company.

Water heater, brand new, was not working. Called Collier and they showed up on time and very professional. They did a great job, kept it clean and my water heater is working now. Highly recommend they guys.

Elderly abuse company. If you do business watch out. Marian is very rude and obnoxious. Installed a sensor in 5 minutes and charged $165. Sensor was defective. New sensor received under warranty and Collier wanted $90 to install. Rheem water heater rep said too much. Big time rip offs for elderly. Classic case of abuse.

Did not replace the whole valve. They have to sent me a new valve and a new labor code.

I spoke to John on Friday 5/24, he told me I shouldn't worry that my check was stolen out of his truck. My personal information is already on the Internet, so it's not a big deal. Perhaps he doesn't realize anyone can do anything with a routing # and checking account #, let alone my personal information (name & address).
Anyway, please note that when you are paying this company they will keep checks in their vehicle for days until someone safely brings it back to the office. And! If your check goes missing because of their blatant lack of responsibility - it'll be your responsibility to call your bank for a check stop (which they will charge you a fee for) and they'll expect you to drive your happy self to their office to pay them. They will take zero responsibility. They offer no apology, they will simply say it was the ""thief's fault not theirs"".

We bought our home 10 years ago and have been using Collier Plumbing ever since for everything from broken garbage disposal, new water heater, water leaks, hose bib repair, clogged drains, new sinks, etc. I've called around to other plumbers and Collier's rate is always the lowest. Yes, plumbers can be expensive but they are very reasonably priced, quick and always arrive on time. My husband even uses Collier for his commercial business. I'd recommend them 100%.
