AC went out, first guy came took out my delay, disconnected the kickstart from its own capacitor, never questioned why kickstart has it's own capacitor, just went ahead did it anyway, got it running for a week, down again, new tech came, says it's the kickstart, Replaced a $40 part for $260, which only took 15 minutes to replace, horrible.. this was a mistake on my part, a week later, AC down again. Another tech came, ohhh it's a bad capacitor!!! We'll why didn't they figure that out in the first place. I think all these guys do is replace parts, I don't think they do any real solid technical diagnosis of the system, I fear that I will see them again next week. They're good at replacing parts which I can do but I'm looking for real professionals who can do solid AC work, find causes and understanding different types of systems. Gundlach techs are nothing but cookie cutter parts replacer company. read more

WATCH OUT FOR THIS COMPANY. I needed a plumber. First time in at least 10 years. I didn't "know" one so I called Gundlachs, who I knew only from ads on TV. Ben came out said their flat rate was $540 to repair a leak in my water main, but because of the confined area to work in, it would be another $100. So $640. I had no idea if it was fair or not, but it sure seemed high. I said I would let him know, I needed to talk to my husband. He tried to pressure me to make a decision that day, based on their workload if I waited he didn't know when they might be able to get back out. I went to my Facebook community and asked for recommendations. I was provided several. I got additional quotes from 2 reputable plumbing companies that had multiple employees. (so I'm not comparing Gundlach's to a one man show that could low ball a price). The hourly rate was close on both new quotes and very reasonable. I agreed to pay PAYLESS PLUMBING $65 per hour and they estimated 2-3hours. It took Chris Jackson from Payless Plumbing about 3 hours and my cost was $212 including materials. ANY DECENT PLUMBER CAN PROVIDE QUALITY SERVICE, AND IT DOESN'T MATTER IF GUNDLACH'S GUARANTEE'S THEIR WORK FOR 2 YEARS. FOR $640 I COULD HAVE HAD IT REPAIRED 3 TIME AND STILL SAVED MONEY. The final blow.... They charged me a $49 trip charge to come out and try and rip me off. They wouldn't come out unless I gave them my credit card over the phone. I wish I had checked Yelp before calling them!!. read more

I used Gundlachs a couple times and never asked for a quote. I just called and said I need my hot water replaced, or I have 2 toilets that need to be replaced and they would come over and replace the items and I would pay the bill. This time I called and asked if they would come and give me a quote on 4 different things I needed to get fixed. They said they would but it would cost me $50.00 for the quote. So much for being a loyal customer, their loss. read more

Called them today to make an appointment to get the condensation drain on my roof unclogged. I've had other plumbers do it before but thought I'd try Gundlachs. Once I explained the issue they wanted to send an HVAC tech to look at my AC. I told them it's a plumbing problem. They then said they'd send out HVAC then if it's a plumbing problem they'll send a plumber... But get this... I'd be charged for both call outs. Told them I'd call someone else. They said Ok and hung up on me. Basically they turned my business away. It won't be coming back. read more

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! read more

I was recommended by a family friend. My heater was broken and it took them two days to come out. Then they wanted me to pay a huge amount, and then tried to push their $20 a month maintenance program. I get that, but seriously, the price was way too high. I know I can find just as good service for more reasonable price. On top of it, I gave them a second chance to fix my leaking sink and then they told me it was going to be cheaper to just replace the sink as it would cost almost $800 to repair it!!! But another family friend came by and fixed the leak for free, so what even was their purpose? Their diagnosis fee is reasonable, so I appreciate that. Other than that, I'm not sure I will use this business again. Too rich for my blood. read more

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. read more

I understand that this is a large company with a high overhead I'm sure, but I have found that their prices are high, you should get a second opinion on their estimates. read more

I would recommend reading all the reviews posted for this company. They have a middle of the road rating because they have poor customer service. They put a lien on my home because they under billed the HERO program by just over $1000 dollars. They could have billed the entire amount but due to their error did not. They messed up our rebate paperwork twice before getting it correct the third time and decided to say it was our fault they messed up. This resulted in a lower rebate payment than they promised. They also messed up on my neighbors paperwork resulting in a lower rebate payment for him. The office staff is very unprofessional and unwilling to work around problems that they themselves created. I would recommend calling another company for any work you may need done and avoid the headache this company will cause you. read more

Excellent service. Highly recommended! I called them in after getting an extremely high quote from another HVAC company. in the end, Gundlach's saved me $500, which was pretty sweet. read more

in reply to their 'fabricated' response, first  I would like to  note,  that only a wk later I went to change the filter in my AC unit and the 'inside' of the AC unit was absolutely FILTHY!!...something that i never experience with any prior service visit!....so this 'newbee' they sent me did absolutely nothing regarding 'cleaning/servicing' my unit....so not only does this person have no brains...as you can read below (to stand right in front of a sign posted on my back door that says 'no back door access...use front door ONLY, yet he doesn't bother knocking at the FRONT door...like NORMAL people would...and just is ready to drive off!), but he is the laziest service rep I have ever dealt with (and this owners(?) stating there were prior issues with other service visits are fabricated...i never had ANY issues with ANY other service reps in all the years of doing business with this co......makes me think this 'lazy newbee' was some relative of someone in the co.!). Anyway, GLAD TO BE RID of suck an UNPROFESSIONAL service! this was my husband's reply to owner(s) letter of cancellation, that gave us no reason as to why cancelling (and now only getting a fabricated one!): on the June service visit here, my wife informed me that the driver went to the back door instead of the front (where on the Back door a large sign is clearly posted stating: "Use Front Door ONLY - Back Door is NOT Accessible", and that sign is not only directly on the back door, but also on the Front of the house that one can clearly SEE as you MUST walk by it to get to the back door, yet your service rep chose to just ignored these signs). Since the back door cannot be opened, my wife waited for him to READ the signs, and come to the front door, instead he got into his truck and she heard him starting to drive away!  She had to immediately run outside in her stocking feet to be able to stop him in time from leaving, so naturally she was upset asking why he can't read signs, and why he wouldn't 'naturally' come around to the front door? He had nothing but excuses that made zero sense....saying: 'didn't know if you still wanted the appointment', and  'I didn't see a car so thought no one was home' (... really?? that was his 'excuse' for being too lazy to knock on the front door?...we only own ONE car, and it's what gets me to my job, so WHY would there necessarily be another car in the driveway?), plus who automatically goes to a back door of a house they've never been to, instead of knocking on the FRONT? My wife said nothing more to him after hearing such ridiculous excuses (thinking there was something wrong with this guy -plus he later was irritated because he had to use the FRONT door when coming in and out, due to the back door being unusable)...which was never an issue for all the service people we had prior, and who KNEW their job and were very nice as well (re: there was NEVER ANY issues when these service people were here, like this owner NOW is fabricating). So my wife just waited for him to do the cleaning, and she even asked him if he wanted a cold drink or water, because it was so hot that day, and he had to be outside part of the time. That is 'hardly' the basis of  someone being 'unfriendly on multiple occasions', as you claim, (rather, from his actions, this is obviously a man who doesn't like his job). She also told me, after he finally was done, that it appeared (re: being the 'only logical explanation' of his actions/comments) that you sent some newbie out this time round (instead of the regular guys we had before) because this one spent most of his time on the phone asking for advice, so this would also explain his apparent laziness to just want to immediately drive off, instead of even coming to the front door in the first place. I suggested she file a complaint about him to the company, and she declined and said that maybe he'd get his 'act' together for the next customer, so what good would complaining about it do anyway - he'd only deny it all (which I can see now by your canceling our service, is exactly what he did).  She told me she even thanked him when he left, which is something I certainly wouldn't have bothered doing, after his urgency to just drive off on her in the first place. So if that is how you do business, by stressing out customers via sending out people who don't know what they are doing, who are in such a hurry to not want to do the job they were booked for, and who apparently aren't even happy with their job in the first place (instead of sending us the 'regular/educated' service guys who came before - they are the ones who don't just try to drive off' but instead take the time to read the posted sign(s) & use logic by going to the Front door ...not a person's Back door, which isn't even the norm when coming to someone's house, especially for the first time) ,  then we certainly don't want to 'give' you our business either, and we will certainly advise others to avoid your services at all cost read more

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! read more

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. read more

Buyer beware!!!!! Smile in your face and rob you for your money. I have 3 disabledpeople in my home and my tank less water heater went out. The gentleman told me the lowest he could do it was for $4000. Being that I needed hot water for my 2 children I trusted what he was saying. I found out 2 days later that they overcharged me by $1500 over any other company for the same exact work. It's really sad that people feel that it's OK to rob people like that and stead of try to get repeat customers. I've loved multiple messages for the owners or at least a manager of a call me and Obviously I'm not important enough to get a return Phone call. I just think it's pretty disgusting $1500 is a lot of money for a lot of people and the fact that you can gouge people that badly should say something about your company or a head lease or sells people that come out and do the work. Thanks again read more

Needed a simple fix for a leaking shower faucet. Convinced me that they were the "Nordstrom" of plumbing and also that the parts I needed were expensive and very difficult to get. I believed them and paid $500 for the work that took longer than necessary and still was a problem after they were done. Had someone else come in and fix it for $90 the right way and they showed me where they got the "difficult" parts to find readily available locally and far cheaper than Gundlach charged me. When I asked them for my money back they wouldn't refund me and refused to admit their fault. Terrible company. read more

I spent an entire summer with Gundlachs trying to figure out my A/C woes. They were diligent, helpful and polite. They troubleshooted what ultimately turned out to be a PG&E problem that caused my A/C system to malfunction. Everything is good now, they maintain the unit for me and they've become indispensable. Very reasonable for the work too. read more

Just finished a major energy upgrade; new HVAC, full attic and duct re-sealing, new insulation, and all new energy efficient windows. During the process we were blessed to have worked with Ryan, Cruz, and even Ken, the owner. Each of these professionals gave us great energy recommendations, personalized service, and the job was completed to perfection. I don't offer these laudatory comments easily. My expectations are generally high. I always look for scams, bait and switch tactics, and I generally distrust "salesmen". This was my first interaction with Gundlachs, so all of my guards were up. During each phase of the process, these defense mechanisms were overcome by clear answers and work that met my expectations. There are any number of good, local companies that probably could have done any one of these projects and maybe some would have even been less expensive. What I most appreciated and validated my choosing Gundlachs, was their comprehensive approach to my whole home energy upgrade. In the end, I'm happy we chose Gunlachs and it was a true pleasure working with Ryan, Cruz, and Ken. Great job guys! read more

Last summer we called out Gundlach's to look at our AC that had not been working properly. We were afraid we were looking at having to replace the whole unit. Turns out they found that it was only a switch that needed replacing, not the complete AC unit. We were impressed with their professionalism and grateful for their honesty. We will certainly call on them again in the future. read more

Good service, but bad pricing. To fix two leaky valves, replace the dryer, and add 7 lbs of new freon, they quoted me $1400. I called Hawley's AC but they were booked for the next 9 days, but they referred me to Hubbell Air. So, glad I called Hubbell Air - not only was Ray from Hubbell Air friendly and diligent, but he only charged me $680 for the same work. I DO NOT recommend Gundlach's. read more

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 read more

Last week my AC unit was leaking water through the roof and to top off it wasnt cooling the house! I called Gundlach's and they took care of it with a reasonable price! I would recommend them read more

So very impressed with the honesty and integrity!! Thank you so much for fixing my plumbing!

I had a horrible experience. Gundlach's came out and serviced our A/C system and pointed out a part that needed to be replaced. A month later and our A/C system will not cool the house and runs all day. The house was so hot that we had to stay with relatives since our son was sick and just came home from the hospital. After a few visits, they still could not figure out what was wrong with the system and never fixed it and still charged us. We decided to replace the A/C system after a week of not being able to live in our house. The worst part was when we tried to go our separate ways from Gundlach's. We had signed up for the comfort club on their first visit. When we tried to cancel after the first service was paid in full, they wanted us to pay for the discount that we had received from the comfort club. They stated that they guarantee their work for two years which is why I had to pay the difference. Some warranty, the system and the part failed in less than a month and they could not fix the problem. I would not waste my time and money with this company. read more

We just completed an energy upgrade with Gundlachs that included a new HVAC with a four zone system, all new duct work, attic sealing, attic insulation, weather stripping of doors, all new grills/returns, exhaust fans with motion and humidity sensors, and updated our water heater to meet code safety restrictions. I have never written a comment on Yelp but I feel that Gundlachs is worthy of a superior recommendation. Gundlachs exceeded our expectations with outstanding levels of service. All of their employees are hard working, dedicated, friendly, energetic, professional, pay attention to detail, personalize service, and are eager to please. We immediately noticed the difference in efficiency and the quality of the air as soon as the new air conditioner was turned on. The Carrier Unit is quiet and the air is definitely cleaner and easier to breathe. I can already tell that I will not need to dust nearly as often. Furthermore, I have family members with asthma and the reduction of dust and pollutants will make a huge difference in the quality of the air in our house. Our successful energy upgrade provided us with a home that is safer, healthier, more comfortable, and now is energy efficient. I highly recommend Gundlachs and want to thank the owner and all of his employees on this project for a superior job completed in a timely manner. read more

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. read more
