We have had nothing but wonderful experiences with Welzig. Scheduling is simple and quick and every technician we’ve had is professional, efficient, kind and seem to genuinely enjoy what they do. Cameron Ryan helped us fix a gas leak and was thorough in his explanation and job and just a really nice and knowledgeable man! Very grateful for Welzig to have saved us several times.

Cameron was an excellent tech. Explained what he was do8ng. Went the extra mile to warn me and advise on whats needed. Liked and appreciated his service!James was a superman installer. He was amazing w skill, knowledge, and dedication. Liked how he explained what and why he was doing certain things. Gave me confidence in the new furnace and additions I bought.

Welzig was great to work with! We were without heat for 5 days and they moved us up the list twice and were able to come out today! Jake was amazing! He explained everything very well and was professional, friendly and was rocking a killer mustache! 🤌🏻 We will definitely use them in the future if needed!

Jesus did a great job today! He was kind, professional, and did a great job explaining possible solutions/repairs for our furnace. I also want to give kudos to Bob. He was able to fix the furnace! He was also professional and did an amazing job explaining the issue. I also want to give kudos to Carter. He did our hot water heater/furnace check and did an excellent job! He was kind, professional, and helpful. I’ll always use Welzig!

I was at my girlfriends ranch visiting and Jake was servicing the furnace. WOW! What a great guy and company! Friendly, articulate, very reasonable service fee. I will definitely use Welzig for issues at our place in the future. His apprentice, Carter, will be a great worker for this company. Great folks. Jake is sporting a super mustache too.

So we had an appointment for our yearly club membership tune up for our A/C scheduled for later this month. I called this morning to see if they had something earlier. The young lady said I could be placed on an earlier call list.. which was fine . well she called back a few hours later and bada bing bada boom she let me know they had a technician on the way , Eric called and said he was on the way. He was knowledgeable , courteous and explained everything he was doing and even made some thermostat adjustments we did not know was a good way to save energy . Eric had a good sense of humor and actually listened to our concerns. Great experience. We have been Welzig customers for years, and dont plan on changing , we will be requesting Eric in the future.

Welzig was the original heat/air/plumbing contractor for the Greens at Ute Creek development…20+ years ago, and we have Welzig service every 6 months to maintain/upgrade heating/cooling/plumbing systems.We were fortunate to again have Cameron Ryan as a service rep. do a pre- winter systems inspection. Not only was Cameron detailed and efficient (as usual) he had a number of suggestions and explanations to aid in smooth operations for this winter. We look forward to having his excellent service again. J. Adams

Saul and Anthony arrived at 9am, installed the new furnace, cleaned up, then showed us how to use the new thermostat (modern and quit fancy!) before leaving around 5:30 pm. Very satisfied with Saul, Anthony, and the Welzig team.

Had the best Technician on Saturday! Jake Davies was very professional, easy to talk to, fun to listen to and explained the problem where I could understand the problem. He was complete with regard to every detail, great care and completeness!! Plus his profile was comforting to know before he showed up. A very nice surprise these days. Now I know who I can depend on. Excellent job Jake!!

Bob was cheerful, courteous, and very knowledgeable. After he serviced our boiler, later in the evening we detected a problem. I called the answering service and Bob returned at 8:00 pm and quickly corrected the issue at no charge. We are very satisfied.

I have had the BEST experience with Welzig. Before every visit they would text me a picture of the technician who would be coming. That small detail always made me feel safe. I got to work with James a lot. Not only did he do an excellent instillation, but he also was courteous and kind about addressing any concerns or questions I had. I highly recommend.

Welzig has taken care of our furnace maintenance plus installation of new furnace over the last 20+ years . They are a very professional and customer friendly company. We highly recommend their services.

Review 13 (2024-09-17 - Rating: 5)
Sadly, my 15 year old AC unit died the other day… right in the midst of a 90+ degree Colorado summers day. I needed to get things handled quick and turned to Google. After calling several companies I decided to go with Welzig for the job. Their prompt response time was incredible, and the top shelf level of customer service they demonstrated start to finish… impressive. When it came time for the actual install, techs Logan & Juan did a fantastic job. And Michael on the sales side was equally as good. They were efficient, clean, knowledgeable, friendly, etc. I quickly knew I made the right choice in HVAC companies. I would recommend Welzig to anyone needing timely, fair & high quality HVAC work!!-Steve (Dacono, Colorado)

Welzig installed a new tankless water heater, water conditioner and automatic water shut off in my home. Gerry came to my home and showed me all the options to replace my broken water heater. He discussed which options would best suit my needs. The installation started the next day. Gerry and Roberto were timely, clean and considerate of my home. When the job was done everything worked perfectly and Im so happy with my new water system. I highly recommend Welzig, Gerry and his team and I will continue to use them for all my HVAC needs.

I would like to give a big shout out to Cameron. He did an excellent job when he came to service the furnace at my home. He was prompt, courteous, knowledgeable and efficient. All my questions were answered and He even took the time to review with me how the tankless water heater worked. I so appreciated his cheerful kindness. Looking forward to having him help me out with all my heating, cooling and electric challenges in the future.Please excuse the tardiness of this note, as I was experiencing technology problems!Sincerely,Diane Richey

Joel is fantastic! Highly recommend. I had no AC all summer. Joel worked his magic today...Now I have AC!!! Joel is VERY kind, Very kind...honest, knowledgeable, detailed, clean, great communicator, very chill. He is very quick to understand my AC unit should not be on a roof where the entire house vibrates. He immediately knew what the right solution should be. I would love to work with Joel again. I highly recommend.

Welzig went above and beyond! Logan Stuckert and James Miltersen were so great. They took my 58 year old cast iron boiler out from my crawl space and my water heater and put in a new boiler and tankless water heater. It took them 3 days. They worked long hard days and made sure everything was working good. They really cleaned up the area and I can tell they take pride in their work. They were amazing! I have already referred them to a friend. I trust them and feel good about using them again! Thanks James and Logan!

I have been working with Gerry Holm, licensed master plumber, at Welzig on a project to replace my main line & reconstruct my bathroom. He is professional, knowledgeable & detail oriented. Gerry has 25 years experience. My father was a licensed master plumber & owned a hardware store, so I know the importance of using a true professional. 5 Stars from Donna Oleston.

A big thank you to Cameron Ryan, the technician that come to our home to fix the furnace issues. He was thorough, explained the issues and even communicated the issues we were experiencing to the Xcel personnel. Thank you Cameron! Highly recommended for our heating needs.

Bob and Logan did an excellent job coming out on short notice, diagnosing and resolving our issue in less than an hour. We’ve been very satisfied with the benefits of Welzig’s platinum service package for many years now. Keep up the good work and thanks again!!

Review 31 (2024-09-02 - Rating: 4)
Erik was the technician Welzig sent over to check on my AC. His service was very thorough. He explained what was the problem he found in great details. He also provided very good suggestions for the issues for both short terms and long terms. I certainly would use his service again in the future. The reason that I have 4 stars instead of 5 stars is because the service was not cheap. The charge rate is from the company. The technician does not have much control on it.

Review 32 (2025-01-03 - Rating: 5)
Mark was very professional and worked on our furnace like it was his own. I would highly recommend him for furnace work and will request him in the future.

Review 33 (2024-07-13 - Rating: 5)
It’s Saturday, 100 degrees outside, company is arriving tomorrow and the AC unit quit working. I called Welzig because they always give me great service. Again, they went above and beyond. Mark arrived in 30 minutes and had the problem fixed shortly thereafter. He was professional and easy going. The price was reasonable and I can’t thank Welzig enough. Quality people that do quality work. Thank you.

Welding Technician Mark Ritz was exactly on time. The notification system including a photo of the Welzig employee is wonderful. Upon arrival, his first time here, he was shown the 2 units for the checkup, shown the outside water system and the mini split and central air controls. He was very diligent in minding his feet protective covers, and very thorough in his explanations of the various phases of the service. He was very professional. He is welcome to be our technician at the next scheduled preventive appointment.Thank youDon

Fantastic service with friendly providers. Jake was super helpful and honest when describing the concerns with my old system and helped get me a quick solution. Logan installed a brand new system the following day and walked through all the questions I had!

Review 41 (2024-09-16 - Rating: 5)
Both Bob C. and Cameron Ryan were very professional and knowledgeable on the heater repair.I would highly recommend these two technicians at Welzig and hope that the new ownership respects their skills allowing them to continue to use their expertise for as long as they ( not the company) are allowed to do their job and not to be pushed by trying to increase jobs per day or in any other way to improve the bottom line of the company.

I have been super impressed with Welzig Heating & Air. My HVAC system needs to be replaced and from the diagnosis to the sales consultation, they’ve been quick, honest, nice and communicative. Casey came out, walked me through all my options and when I asked for a recommendation, he didn’t say the most expensive option! I felt informed and there was no pressure. I wish there were more than 5 stars.

Review 45 (2024-09-20 - Rating: 5)
Large HVAC job just completed. From Cassy and Casey Welzig presenting, Cassy closing on the sale, and watching James and Juan install with precision, we were very impressed. All were more than courteous, attentive to all our questions and concerns, and everyone was extremely professional. Thank you Team Welzig!

I had a water leak from the exhaust pipe of my furnace. Dave came out and assessed the situation and sent out a technician, Roberto to address the problem. Between them, they expeditiously resolved the issue.

We scheduled an air conditioning service. Jesus Regalado Espinoza was our technician. Very respectful, knowledgeable, good communicator, timely response to our request for a bid because he discovered a potential leak on our gas hot water heater seal. We’ve used Welzig a couple of times and they’ve been easy to work with. We are considering using them to install a new hot water heater.

Great company! I had their company install a furnace years ago. I was so happy with them that I used them again. Saul was very friendly, efficient and fast. Scheduling happened within a day and they lent me a cooling unit until my unit was installed.

Welzig installed a furnace, separate AC and hot water heater for us several years ago and their installation team was incredible. We have been pleased with their annual service plan (and service). Dominick performed our most recent service. He was courteous, knowledgeable and did a thorough job.

We had some issues with our AC unit, but Welzig has been great about getting people out to fix it issue and did being their work. Bob was really great and stayed late to explain things to us and how to run out AC more efficiently. Than you Welzig, Bob and all the staff that helped us.

Review 52 (2024-06-12 - Rating: 5)
I have been a customer for almost 20 years. I recently had the pleasure of working with Michael M to purchase our second heating and AC unit. He listened to our needs and our habit of keeping our home very cool in the summer. He then built tailored options for us from their high quality products. He was very professional and knowledgeable and answered all questions we had. We never felt pressured or rushed to make a decision. The next day James and Logan professionally and efficiently installed our new Heat/AC unit. Yes you do have cheaper options. However, you will not receive the professional customer service team or the highly trained and knowledge technicians. Welzig gives me peace of mind when making such a big purchase. I know they stand behind their products and instillations. They take care of their customers and to me that is priceless!!

After two others had come out to remedy the situation, something esoteric was going on after all. Cameron is the god of HVAC and Tech! He stayed with this troublesome situation and actually Heard the problem and identified the likely cause. Turned out to be the solution! He has a great attitude, a genius for the profession. Many gold stars!

Bob came out and helped us identify a mess of problems with our boiler and radiator system. He was knowledge and friendly, and was able to walk us through a plan to get our 70 year old house back on track. Looking forward to having them be our servicer for the years to come.

Where to begin? From the estimate to the actual install I couldnt have asked for more. I received texts saying when they were on their way (Always prompt). Cassie notified me when a slot came open and gave a discount to take it. Saul, James, Juan, David, and Anthony (and Cassie and Bridget) never left me uniformed for a minute. I had a 55 year old boiler replaced AND a split airconditioning system installed in a matter of days and they researched and provided the paperwork for over $2000 rebate from Xcel. They are SO professional, patient, courteous and prompt that my nerves about replacing a rusted, in the crawlspace, boiler are completely gone. Kudos New customer for life.Oct 2024 UPDATE:Welzig continues to take stellar care of our HVAC needs. I dont know how we survived 28 summers without air conditioning. James and Bob continue to maintain and dial in our new boiler. Every single tech/installer has not only been completely knowledgable and professional but truly good humans as well. Shout out to Lindsey and Cassy for keeping me informed of maintenance schedules. My Xcel rebate arrives today. Thank you David for completing and submitting the paperwork to BOCO.#1 Company with the best staff.Carole

In 2012, I had Welzig install a replacement furnace on my townhome and they did such a great professional job that when I started thinking of replacing my 23 year old AC unit, I decided to call Welzig again. Met with Michael and he took me through all the basics of heat pump vs AC unit and I settled on a new Bryant 2 stage unit. James and Jimmy were here today and spent the day doing an outstanding job of installing the new unit in my townhome. They were professional and at the end of installation took me through all that was done with new copper tubing, drains, ducting, etc. Then we went outside and after James turned the AC unit on via thermostat, he waited to make sure the second stage kicked in, and took the time to explain everything to me. Could not ask for better service. I highly recommend Welzig for AC and furnace installations, and ask for James and Jimmy to do the installation...youll be very happy with their work.

Review 66 (2024-06-20 - Rating: 5)
Loganwas on time, great service and explanation of what is expected. Got days ahead so Logan provided some guidance on how to keep house cool for the few days until reconnecting AC. Recommend Welzig Heating and cooling above all others I’ve worked with. Have them coming back out to connect and clean out all my ducts and system too. Update:6.20.24 reinstall was great. Dave was masterful and finished all before the rain came. And Jesus worked out the final issues to get us towards the next step in our maintenance/cleaning effort.

Welzig is always able to help with whatever heating or cooling problems we may have. They set appointments without long delays and then actually show up on time with someone qualified to solve the problem.

Jake was terrific and deserves to win the mustache competition.

James and Logan installed a new split-mini heat/cool unit in the clubhouse for our recreation association. Their work was perfect in every way. Friendly, knowledgeable, detail-oriented… and competitively priced. Casey also helped us troubleshoot a particularly mysterious sound in our HVAC system, with success! And James replaced a water heater in our home, and in the process fixed a nagging issue with the water supply to our humidifier. Cameron serviced our cooling unit and went above and beyond to clean it to perfection, and even recommended some upgrades to make it function more smoothly. Everyone at Welzig is beyond my highest expectations for communication, timeliness, and quality of work.

Cameron Ryan revived our Air Conditioning system from non functioning to working perfectly. He arrived on time and analyzed the system and began to first clean the physical unit after removing the outer shell. There were several internal parts that needed to be replaced, and he also recharged the coolant, I believe. Our basement area is always way cooler than the main floor of our home.Cameron explained that he changed the thermostat to recirculate the cool air with the warmer air, so now the temperatures are the same and much cooler.I also appreciate that Cameron served in the U.S. Air Force.If you call WELZIG for service and Cameron shows up, you have a great technician to fix your systems.Maj.

Jake Davies is great to work with. He was prompt and arriving and was quick to get resolution to the error code with our AC communication issue. He showed us what the problem was with the photo that he took. I was pleased to know that there was a root cause.He made the recommendation for a surge protector on the outside unit. I’ve never given thought that being a possible risk to our warranty. Jake noticed that the furnace condensation filter needed to be replaced. Was pleased that he had that available on his truck.Jake is very knowledgeable of our system and I look forward to having him return for future maintenance.

I have used Welzigs services twice in the past two years. The first time was to fix a leaking AC unit, and the second time was to install a tankless water heater. Both experiences were pleasant. The team was professional, arrived on time, and explained the details patiently. Although installing a tankless water heater typically takes a full day, Welzig sent two technicians, Logan and his teammate, to complete the job in four hours since the work started in the afternoon. This was much appreciated, especially since our heater had been broken for three days.

Weve been a customer of Weltzig for many years. They installed our furnace, AC, air purifier, water heater, and thermostat. We also purchased a maintenance package. One of their service techs, Mark Ritz, was just here to perform the yearly maintenance on our AC unit. He did a thorough job of checking everything, cleaning, and replacing the air filter, all covered under the maintenance. Mark did a great job of going over everything he did. I recommend Weltzig, Mark, and all the prior service technicians that have been to our home and the helpful and friendly office staff when we call.

Review 133 (2024-06-15 - Rating: 5)
We first connected with Welzig in September 2023 to discuss a quote for air conditioning. Casey spent about an hour getting to know us and walking through what we were looking for. We have no ducting in our house but didnt love the idea of the wall units in the main floor of our house. Casey was able to offer multiple solutions such as strategic placement of units and crawl space ducting. Since we were approaching winter we decided to hold off on the AC and have them install a new heater instead. We ran into a few issues with the heater - installing a tankless boiler at high altitude with propane instead of natural gas was not the norm. Welzig was incredibly attentive and fast to deal with the problems including sending multiple techs, spending hours on the phone with Rinnai and even having a Rinnai rep come to the house to troubleshoot.Because of how professionally and genuinely they responded to the problems with the heater we decided we wanted to work with them again to install the AC that had been quoted a year earlier. Saul did incredible work and truly went above and beyond everyday to make it what we wanted. Everyone who visited our house was so pleasant - it was enjoyable for them to be around. I dipped my head into our crawl space and am blown away by what Saul and his team accomplished down there. We have recommended Welzing to neighbors, friends and family because of how attentive and accommodating they are.

James Miltersen and Roberto Santana-Hernandez did an exceptional job of installation of a Rennai tankless water heater. Michael Moorehead did an exceptional job of system diagnostics. These Welzig technicians are very skilled and very professional. Scheduling was smooth, and notifications of who was arriving and when were superb.James MIltersen returned to upgrade a gas line to meet code requirements and did a superb job.Dave Kaplan-Gomez analyzed the system and worked with the inspector to come up with a plan for the gas line upgrade, and the inspection went smoothly and passed all code requirements.In June 2023 James Ives quickly diagnosed a problem with the A/C system and made a repair on the spot. Welzigs response was fast and economical.On July 27th 2024 Cameron Ryan successfully diagnosed and fixed a vibrating knock in our plumbing system. Previous attempts to fix this with surge tanks and lower water pressure failed to fix the problem. It was caused by the recirculating valve in our new Welzig-installed tankless water heater, which Ryan removed with our agreement, and the problem disappeared. Mr. Ryan is a first-rate diagnostician.

Welzig came through when we really needed them. Our a/c went out on a Wednesday evening, the night before we left for a close-by out of town wedding. The plan for the morning after the wedding (Sunday) was for the wedding party & other guests to come to our house for a post-wedding reception. Added to this is that we had 4 adults and 2 small children guests staying with us and the temps were in the mid-90s. I panicked called Welzig on Thursday morning before we departed and worked with Bridget and Lynzee. Despite a very heavy workload, they said they would do their best to get a tech to our house on Friday or Saturday. I got a call from them on Saturday afternoon saying that their senior tech, Bob, was getting dispatched to our house to get the a/c fixed. He did a great job, was very thorough and called me before proceeding with the repair work and discussed what parts needed to be replaced. The party was saved. Welzig charged a very fair price despite the quick reaction I requested. Welzig was also great to work with regarding a neighbor letting Bob into our house in our absence. I plan on using Welzig in the future.

We had Welzig install a new heat pump, furnace and steam humidifier. Casey Welzig came and gave us all the information we could want. He was personable, knowledgeable, and into it. He gave us options. We decided on what we wanted, and two days later Jim and Anthony arrived for the installation. We were impressed with their work ethic, and knowledge. It took two days to install everything. It all worked when they finished and we knew the basics of the new thermostat. Casey came back and double checked the workmanship, went over the thermostat controls, and answered questions. The city permit inspector was happy we had Welzig do the work, because they always do the job correctly. We have used Welzig for over 20 years and they have always done a good job!
