Recommended Customer Reviews

THIEVES, THIEVES,THIEVES, please read throughout
The service was great even though they showed up late. Henry, the tech I dealt with was very helpful and knowledgeable. However, when he presented me with a six hundred and eighty some dollars invoice, I asked him to double check his itemized statement. I figured he made s mistake and added cost of material. I supplied the garbage disposal and the Sink faucet, Henry only provided the labor. He was at my house for 1 hour and 50 minutes total, including personal blablabla conversation and he took his jolly time working. Not to mention they add $48 to your bill just to show up, but it's not part of the labor performed. It's just for them to show up.
I own five restaurants and I deal with plumbing companies almost daily and in five different cities, and the most I have ever paid for plumbing services (as weekend overtime) was 140$/labor hour.
These guys are crooked thieves.

First time out it was 286 dollars to replace rusted bolts and seal for toilet. Home just built in 2013. This was in July of 16 I believe. (Dispatcher told me that and also that I still had warranty till July 2018) I was at work when plumber contacted me and informed me that builder used less quality materials. (In 2016) It's in the kids hallway restroom so I Authorized the repair. Got home from work and was satisfied. Two weeks ago (2018)I call them back out to inspect the bolts because they are rusted again. I used to work there so I am familiar with the two year warranty. Plumber showed up at my door with no tool bag and just a phone in his hand. Walked straight to the hallway restroom. Took pictures and walks out with not one word. Comes back and tells me it will be 286 dollars to complete the repairs. Astonished, I do my best to maintain my composure while I do my best to explain the whole scenario. Plumber doesn't want to hear it. So I ask to speak to a manager. ""George"". I hear him say what's he want to speak to me for it's not under warranty. So I attempt to explain to him that his plumber is trying to charge me for the exact same repair that was made their last visit. His says oh let me look into it. I'll have my guy take some pictures. So the plumber back in my home taking pictures again. Even though he just took them. Plumber walks out to his van. Sits there for a while, comes back and tells me yeah it's not covered under warranty. In disbelief at what is transpiring right in front of me (the unprofessionalism-my words can not express the reality of how all this was taking place) I attempt to call the office and speak with one person then she hands me over to Jessica. As I am explaining the situation to Jessica the plumber comes up to me and says hey they want me to leave I just gotta go. I'm leaving. I ask him for something in writing which he does not give me? Jessica informs me that she will look into it. I ask her to please contact my wife with the outcome because I just couldn't believe the unprofessionalism I was just met with. She says okay. My wife gets home and I asked her the outcome. She says the plumber says we need a 900 dollar repair. (How did the cost of repair now change from 286 to 900?) At that point I was at a lost for words. Keep in mind I used to work for this company, so I text the owner and inform him that - I now know how his customers feel at the end of the day. His response to me was if I want it done right it is going to cost 900 dollars. But he does not understand at this point everything that transpired. It's not his fault. If I were still his technician I would hope that he would defend me the same way so I get it. But this time Sir, you are and were wrong to dismiss your customer, especially when your plumber represented your establishment so poorly. Honestly I don't know what I expected when they came out. All I know is I spoke with the office and they told me it would be under warranty-when I initially called in to inquire about the whole scenario. They could have a plumber out that same day. The dispatcher said. So I agreed to the appointment. Honestly, my wife just wanted it repaired so I thought might as well see if it's still under warranty, if not it's not no big deal. It was just so odd that the cost he wanted to charge me was the exact same number I had paid. The plumber kept telling me we don't warranty bolts, which I get but if that is the only reason I called them out for in 2016 then what did I pay them for. The seal the plumber probably didn't even change it in 2016 because he told me he needed to pretty much charge me for that repair to get the bolts in-my house at the time was not even 3 years old. He said the builder just used cheap material. It made total sense. Who is their that hasn't purchased a new home to find the builder tools short cut somewhere. This was the only reason we called them in 2016. Just the bolts were rusted. It was weird. No they are rusted again. But per the plumber they don't warranty bolts - ITheir motto is good old fashioned integrity with today's technology. Unfortunately that was not the case this day. So as a consumer you decide if you would like to be the next one writing this post. I normally don't do reviews but with this being the worst customer experience of my entire life, I felt I just had to let it out to truly let it go. Maybe your experience won't be as bad as mine. Or at least I hope not. God Bless.

I called ""On Time"" first to work on floor heater. They called and said it needed to be replaced as you could not get parts to fix. $4,200.00. Then I found Gundlach's who went out and said ""there was nothing wrong with floor heater, just needed to be relit. Yeah, love love love honest company's. Thank you so much.

I was pushed in a corner with a broken bib on an outside faucet. They charged me.....$242.00 to replace a $5 part that took less than 5 minutes!! Yep, YOU READ THAT RIGHT! $242.00!! He knew I couldn't find anyone else quickly and the water wouldn't shut completely off. NEVER AGAIN!

Unfortunately, my elderly parents purchased an HVAC Unit from Gundlach's. Although the purchase was made now over a couple of years ago, I found out from my elderly parent's recently after the fact, that they were NOT apprised of all the rebates they were entitled to of @ least $4000 or more so they paid FULL price of $10,000.
When I purchased my own AC Unit a year before from a very reputable AC company, I ended up paying $3,800 for a 16 SEER (excellent) Unit after all my rebates, which the AC company had graciously apprised me of and even filled out all of the rebate paper work for me too. My parents were also sold things they did not need. I know they (Gundlach's) had to know obviously, that the rebates from the State of CA and PG&E etc., were not ""activated"" by my parents, and I wonder if the huge rebates were ""redeemed"" by anyone there at Gundlach's instead. Hopefully, you all (Gundlach's) there did not cash them in for yourselves. BEWARE of this shady place! I will tell everyone that I can not to do business there.
I feel you took advantage of an elderly couple, but ""lucky"" for the Gundlach's company, now too much time has probably gone by for me to get an attorney on behalf of my parents. Again, it is very disturbing that this level of dishonesty towards an elderly couple was committed. People, make sure you check for and get your rebates from the State of CA and PG&E which, they are still paying out to consumers to this day.
Also check the BBB for another complaint on Gundlach's regarding someone's energy rebate, in which they also screwed that up too.
And Rachel of Gundlach's, you can try to rebutt this/these bad reviews all day long for your company, but a ""spade is always a spade""! If I can help someone to look elsewhere for service or an AC unit that will be great! Especially for any elderly consumer!

Gundlach provided excellent service!! The workers were professional , honest, neat and clean. When installing my new air conditioning unit, they did not leave any residual dust or dirt in the home. Also the staff took great care and worked efficiently to ensure my AC was installed before the next heat wave. -Perkins Family

Ulises was our serviceman this time and he, like all of the servicemen from Gundlach's, was top notch. Ulises was very informative and spent a lot of time making sure everything was right. He was thoroughly professional and did a great job. Thank you.

We have the seasonal maintenance from Gundlach. They are polite, professional and keep our heater and air conditioning running well. They call to make the appointment and come out on time. Dan T. was our serviceman and he was took care of our heater a/c the inside and outside. He worked in a timely manner and directed us on how to keep our a/c running smoothly especially during summer. Thanks!

I have been using Gundlach's as my go-to source for plumbing and hvac services for about two years now. I have had nothing but excellent service from them. They are one of a few companies that actually carry water heaters made in the U.S.A. which is a rarity these days. Two days prior to this review, I found water in one side of my garage. I scheduled an appointment with Gundlach's for the next day. Mike S. came out and spent around 4+ hours working on this problem out in the rain, cold and eventually darkness. A pvc pipe for our irrigation system coming off the main line coming in broke leaking water which found it's way into our garage once the soil was saturated. Mike had to clear numerous roots from a nearby tree which added to the repair time. I had Mike add a pvb to the line going to the sprinkler valves to ensure that water from our sprinklers doesn't back-up into the water coming into the house which also added time to the repair. Mike also replaced part of the main pvc water line that comes up from the ground to the home with thick walled copper pipe and added a new hose bib. Overall, Mike did a great job and was professional as have been all the workers from Gundlach's that have come to my home over the past two years. Yes, they are perhaps more expensive than other companies but they do quality work using quality materials. Thank you Mike S. and Gundlach's for helping us in a time of need.

They are a good company, very expensive!!! they came out twice and never really fixed the problem. The 2nd guy was very good but within a few days the lines were backed up again.. they never really looked into what was causing the back up.. We finally went with another company and they took care of the problem.. Maybe more trouble shooting in the future instead of price gouging customers.. We had all new pipes put in so you lost out on that business..
