The HVAC guys at landgraf are either stupid, liars, or lazy. Needed duct work installed for my new induction cooktop which has a downdraft. The fitting on the cooktop is for 10"x3.25" rectangular duct. They first told me it had to be 6" round because the square duct wouldn't have enough airflow. The rectangular duct actually would have more airflow area (I learned how to calculate area of both cylinders and rectangles in elementary school, maybe these guys don't.) This makes me think these guys are stupid. After my wife called back the front office to explain that there is actually more airflow from the rectangular duct, they called back and said grease would drop down and pool and that's why it has to be round duct. This makes me think they are liars for changing the story. Also these grease down vents have traps and filters. All this is to say even if they are stupid and liars, they are definitely lazy for not wanting to do the job. We should have known better after they charged $200 more than what the quote was for a simple plumbing job to hook up a new fridge and couldn't explain why it was more. read more

I really enjoyed working with this company for the past few years but have had to change as of today due to unreliable service. Our heat has not been working and with two small kids this can only be the case for so long! We were due for a visit last week and no one showed on the day of service, no call, nothing. I let it go and rescheduled for today and when I called at 8am the receptionist said they are really busy and just not sure when they could get to me. It's too bad as I was a loyal customer and while I am flexible, I can only flex so much! read more

Great install! The two installers Chris and Jacob were fantastic. They were professional, great with my pets and did an impeccable job. The furnace and AC look and run great. Chris also spent extra time to make sure my thermostat was configured correctly for my high efficiency furnace. Also, very greatful to Linda and Bruce for getting everything arranged, it's been great working with you two. I have used Landgraf for the last 3 years, they are reliable, friendly and have been excellent to work with! Deepest Thanks! read more

great customer service - great work...cohesive staff. They stand behind their work and are reliable and trustworthy!

I've been using Landgraf for all of my heating and plumbing needs since I moved into my house almost 3 years ago and I've never had anything but good experiences with them. I first hired them to install AC in my house for a really reasonable price and then they did the same for my friend whom I referred. Since then they've fixed clogged pipes, leaks, and recently replaced an old toilet. They even came once early on because I forgot to change the filter in my AC unit and managed not to laugh in my face when it turned out that was the issue (oops!!). Everyone I've spoken to/worked with has been incredibly friendly. Linda (who typically answers when I call) is so sweet and patient, and I've never had to wait an unreasonable amount of time to get someone to come out for a service call. I've seen a few different faces at my house but most recently Joe came over to replace the toilet and my dog was a complete a*hole to him. He had every right to walk out and be incredibly angry at me but instead he was so nice about it, stayed, and did a great job with the installation. They've definitely earned my loyalty. read more

My kitchen sink backed up and flooded my hardwood floors. I called Landgraf and found out their plumbers were in Colorado Springs; even though they already had a full days work, the plumbers stopped at my place and did an amazing job fixing the problem. These guys are knowledgeable , hard working and professional. From now on, they'll be my "go-to" plumbers. read more

I used Landgraf for a large work project and after doing such an excellent job at my office, I decided to try them for my home as I needed new hot water heaters. Calling the office, you speak with Linda, one of the most delightful individuals I have interacted with at a business. She answered my questions and when she needed more information, she obtained it and got back to me quickly. I price compared and their pricing was excellent. The installation was done by Michael and Chris-as professional as you get, keeping my house spotless (despite the fresh snow outside) and doing an excellent job. This was, as estimated, a 6 hour job yet they made my wife feel comfortable as she was home while they were working. This is a company I will certainly be using again for both my business and home plumbing needs. read more

Landgraf never told me that there was a charge for estimates. Landgraf had come out in September of 2019 and was suppose to give me an estimate. They never sent the estimate - so I went with another plumber. Unfortunately 2 months later, I needed another repair and so I contacted Landgraf. Landgraf did not make the appointment time for the 2nd repair and upon rescheduling for later that day - they now stated there would be a estimate charge. I stated Landgraf did not charge before for an estimate - they said I did not go with their company with the first repair. Denise stated she sent the estimate on 10/4/2019...I doubled checked no estimate on that date. It is a common practice to get multiple estimates. Landgraf needs to explain on website and at time of scheduling appointments whether there is a charge for estimates. Upon stating that I would be writing a negative review Denise stated that reviews do not matter. If this is Landgraf's attitude toward customer service - you have been warned. read more

Had a problem with my furnace which never got fixed they just kept trying to rebuild it, eventually they said I need an all new furnace unit installed, so I figured I would wait because it was may and summer was on the way. I than used them for my plumbing issue for my bathroom sink drain which was leaking so they replaced my drain line for my upstairs bathroom but after the repair it wouldn't drain proper. I called in and spoke with Denise who transferred me over to Bob Landgraf, come to find out he doesn't have any experience in plumbing or HVAC never touched a tool doesn't even own a drill ride as can be. Anyhow I went with someone else they changed out my burners on my furnace problem solved, and my drain for my bathroom had back fall so they had to correct the issue. read more

I set up a service call because my furnace smells funky like it isn't burning properly. The tech came out and didn't even open the cover and left. I was shocked to get a bill for 109.00 for the guy to do NOTHING!!! I called and questioned it and they basically told me he did what I asked. I will never use this company ever again. Oh and I took the cover off and found it was dirty inside so I cleaned it out and blew off the burners and the smell stopped. Good thing I got charged for the work I did myself. read more

We have been using Landgraf since purchasing my home in 2004. From water heater replacement, to furnace maintenance and gas line install - these guys are the BEST! Every tech who has been out has been professional and has taken the time to share the reason behind the repair and the functionality. You can tell they love their job and working for Landgraf. They are very quick to respond to my calls and emails. I've had conversations with the owner of the Colorado company and he has been very courteous, respectful and a great guy. I would take these other reviews with a grain of salt - some people can just be overly sensitive. Each tech who has visited my house for work has a long history with the company - that speaks volumes of the ownership and tech retention level is high!!! I definitely recommend for all HVAC, heating and plumping needs. We're in the process of building a new home and rest assured they will be the our go-to heating and plumbing needs!! read more

They installed in May a new hot water heater that is also part of our heating system. They were quick to respond and replace my burst heater. When it got cold yesterday, the heating system was not working. I emailed Bob Landgraf last night and he immediately sent out one of his technicians who quickly corrected the problem. If you have a hot water, forced air heating system (mostly found in condos) this is the company to call. They are a very professional, reliable and responsive HVAC and plumbing company. read more

AVOID. We used these folks for over 10 years for everything regarding plumbing, heating and cooling at our home and all was fine until one day the unfriendly owner answered the phone when I called to schedule a NEW FURNACE installation. He seemed he could not be bothered with talking to me, but when I hung up the phone in frustration he called me right back leaving a voice message calling me rude and gutless. If this is how they really think of their loyal customers who have spent at least $10,000 with them, they should be avoided. Here is a link to the voice mail this jerk left me http://mtnhomes.com/voicemail20121130.mp3 read more

We had a problem with our furnace not lighting on the first try, so they sent someone out multiple times to fix the problem. Each time, he replaced parts in our furnace, left, and the problem occurred almost immediately after the visit. After throwing parts at the furnace without correcting the problem (and charging us big bucks each time) we finally complained to the company, and they sent out a supervisor. The supervisor measured the gas pressure, and said we weren't getting enough gas from Xcel. We called Xcel, and they fixed the problem at no charge. The furnace has worked fine ever since. Had the original technician (Marty) checked the gas pressure instead of just replacing part after part, our furnace problem would have been fixed quickly, and for at least $1000 less than what we paid for the repairs that didn't fix anything. Don't hire these people for furnace repair! read more

If I could leave negative stars, I would. Unfortunately, this is one of the most unprofessionally run companies that I've ever dealt with, aside from their technician Marty. I spoke with Denise and the owner Bob, both were rude and condescending. Denise promised me a refund for services that were done that didn't fix the problem. When I called back nearly two weeks later to follow up on the refund she then said "we're not giving you a refund now". When I started to ask questions she cut me off and sent me to the owner Bob, who was combative and condescending. I cannot understand how the heck this company is still in business, it's unbelievable. I wouldn't recommend this company to my worst enemy. BEWARE. read more

Landgraf has a long time customer from me! We had ARS come out for a plumbing problem about a week ago, they said we needed to spend 10k on a whole new sewer line!! We called Landgraf out for a second opinion and Joe cleaned our pipes out, showed me before and after pipes were cleaned! Huge difference, almost no roots in the pipes!! Thank you Landgraf and Joe for doing what is right for the customer!!! read more

Have been using and recommending Landgraf for over thirty years. Great folks and great service. Never had a complaint - service crew is punctual and courteous. Prices reasonable. Honest, hard working folks. Have them check things out twice a year. You won't do any better- if I didn't believe it I would not recommend them to all my clients. read more

Wonderful service from beginning to end. My furnace broke and I called and they came out the same day and diagnosed the issue and resolved my issue. The induction system needed to be replaced and they ordered it overnight and replaced it at the scheduled time. We were very happy with them and will use this company for all our maintenance and future needs! read more

I have had Landgraf service for over 20 years. They are the best! I have never had any issues with the tons of plumbing and heating service they have done for me. Bruce, Marty and Joe are super, quick and so honest. Nancy English read more

Don't use. We can say this with full authority as we've been loyal customers with Landgraf for a decade. We trusted this company implicitly with their HVAC and Plumbing divisions. Thing is, we just had an incident where their assessment was called into question....instead of answering our queries in a civil, educated manner, we were screamed at on the phone -- even threatened to be sued. The owner is a loose cannon as was already witnessed by another review posted here. read more

I have had a good experience with their field personnel. They don't make me feel stupid are efficient on time and kind to my dogs. The tech Bruce Scurlock even remembered he had been to my home before...at least a year or two ago.....I don't know about the owners..but I have been very pleased with the front line staff who have been in my home. read more

If I could give less than one star I would do that, this joke of a company came into my house and caused more problems than they fixed. If you call them out on anything they do wrong they will call you a liar and tell you to no longer do business with them. They charged over a hundred dollars for one rubber O ring (I guess they charge 100 dollars and hour) I honestly would of had a better experience if i hired a 5 year old to do the job. read more

Stopped using them. 9 years ago, they fixed my furnace but told me that I needed to replace it because the burners were going. A few years later I had someone else look at it. He cleaned the burners and said it had at least another 15 years on it before I needed to worry about it (it has been fine). 6 years ago, they fixed my water heater that they had just installed 2 years previous and said that I needed to replace the entire heating element. I blew that off and it has been fine. They also replaced all the piping from my leaking tub drain which started leaking again a few months later. But in fairness it is an old tub with old piping and probably had to be jerry rigged to some degree. And they also told me I needed to replace my old toilet because the phalange is too small due to it being such an old model. That is debatable, I suppose, but it has pretty much been ok. Anyway, I finally asked myself "why do I keep using these guys when they're always telling me I have to replace everything?". So I stopped. read more
