Welzig Heating, Cooling, Plumbing & Electric

We have used Welzig for all of our HVAC needs for years.. For many reasons. Foremost is the Quality of service and very pleasant employees. Maybe they aren't the cheapest but I honestly believe they are the best along the Front Range of Colorado. Last night my furnace bit the dust at 2:00 am... called their answering service and they had a service man here by 9:00AM. Kudos to James Matheny... awesome technician, very pleasant and courteous. Thanks Welzig

Our furnace stopped working sometime Saturday night we called them Sunday to see when they could get out to look at it. The earliest they could get here was Tuesday afternoon, not much we could do because everybody else was further out. We got up Monday morning and got ready for the day then got a call saying they could get us in around an hour or so, we were happy about that! About 5 minutes later I got a text saying Jonathan the tech was 15 minutes away from the house, even better we thought! He arrived and was totally professional and ready to work, only had to back to his van once for a part. In no time at all he had the furnace up and running, it was a simple fix and made it a minimal change too. I would recommend this company and tech to anyone and everyone I come in contact with, friendly, professional and caring! Thank you so much.

So glad that I have subscribed to Welzig Comfort Club program. They recommended an inspection of my Hot Water Heater and plumbing throughout our home. The pressure relief valve needed to be replaced after 5-yrs due to corrosion of the anode rod. We had the shutoff valves replaced to use a 1/4 turn valve to avoid any future issues with water leaks in the bathrooms. Preventative action as we are in our retirement years and plumbing can always be tricky with leaks. The biggest benefit of this service was when we learned that the reason for the garbage disposal performing so poorly has been due to improper plumbing due to a kitchen remodel done years ago. We had a deep-sink installed with the granite countertop and that crew retrofitted the plumbing and did not inform me that this was required. It was a challenging project to redirect the pipes but worth the price to have this completed since it was not to code. The professionalism of the 3 plumbers that helped resolve our plumbing issues was exceptional. They were very attentive to details on what was needed.

Jerry did not know what a "Yard Hydrant" was nor did he know how to repair one. He wanted to dig the entire 5' pipe out of the ground and replace everything. I stopped him and he left, apologizing. Dispatch needs to realize a little bit about the problem to be resolved before sending someone. At least there was no charge, at least so far...

Outstanding experience from start to finish. Casey in sales spent over an hour patiently answering all my questions, which made me feel confident moving forward. Cassy did a great job aligning the claims with the offer, ensuring everything was seamless. Installation happened just one day after I signed the contract — incredibly efficient. Saul and his colleague were professional and thorough. I especially appreciated that Welzig sent a senior engineer; Saul has been with the company for 15 years, and his expertise showed. They handled the permit process, and the inspector came promptly and approved the work. And the small cooler with cookies? A thoughtful touch that truly made the experience feel personal. Well done, Welzig — highly recommended!

Welzig Heating has always provided quality workmanship in a friendly, dependable manner. For example, yesterday, Cameron Ryan serviced my AC and furnace and thoroughly checked both units. He carefully explained any repairs and modifications that would improve my heating & cooling systems and then successfully completed the actions that I agreed to. I just had another visit from Welzig by Jesse who did an outstanding job reviewing my plumbing issues and corrected everything that was problematic. He explained the work (along with pictures) and the costs involved. It was a pleasant experience in general. Great work.

Had my 15 year old water heater go down the day before thanksgiving, where I would be hosting ten people. I didn't find out until 2pm on Wednesday. From the wonderful people at the office that got my ticket in and someone headed my way 10 minutes. To Jerry my plumber, Welzig was fantastic. Jerry showed up Thanksgiving morning at 8 and had the new one installed by 930, old one hauled out, and hot water flowing by 1030. Awesome flat pricing as well. I cannot stress enough how much me and my wife are grateful for the whole team at Welzig, but ESPECIALLY JERRY YOU'RE THE BEST BROTHER!

James and Casey did a great job troubleshooting our 25-year-old, idiosyncratic radiant heat system. They identified valves and parts that needed to be replaced and were extremely knowledgeable. I appreciated their willingness to patiently explain to new homeowners the basics of our system. Casey gave us a thorough breakdown of pricing on a new boiler, including tradeoffs with different models. Welzig is a highly professional operation and we feel lucky to be able to work with them, given that we live at 8500 ft. Jerry came out to fix a leak under the sink and did a great job!

Cassy at Welzig has done a great job for me! I will definitely do business with Welzig again and will recommend their services! Travis and Anthony installed both my furnace and air conditioner units. They were polite, knowledgeable, and efficient. Even though they ran into some challenges with the air conditioner, they remained patient and pleasant. They cleaned up after themselves before they left each day. Again, I would recommend Welzig for installing your HVAC appliances, especially Travis and Anthony!

Jerry came out to fix a leak on our home humidifier, and he was fantastic from start to finish. He was incredibly friendly and professional, took the time to explain what he was doing, and even shared some great plumbing best practices to help us prevent issues down the road. The repair was quick, efficient, and done right. He treated our home with respect and left the area spotless. Highly recommend Jerry and the Welzig team. It’s rare to find someone so knowledgeable, courteous, and thorough!

We just had our favorite plumber, Jon, from Welzig Plumbing come to the house to do some work for us, and as always, he was amazing! He’s incredibly skilled at what he does and takes the time to explain everything clearly. Jon is not only professional and knowledgeable but also has the best personality — it’s always a pleasure to see him. We truly appreciate his excellent work and friendly attitude every time he comes by. Highly recommend Jon and Welzig to anyone looking for a top-notch plumber

From start to finish, Casey explained our furnace options and Roberto Santana-Hernandez delivered outstanding service on our furnace install. He arrived on schedule, protected floors and work areas, verified gas and electrical connections, and brought the system up to spec. Robert walked us through filter changes and thermostat settings. The workmanship is neat, the unit is quiet, and our home is heating evenly. Welzig Heating & Air earned our trust. Five stars.

I received my first plumbing maintenance with Andy from Welzig, and what a great experience. Andy was through with his inspection and pointed out a couple issues that needed to be addressed. I'm really glad Welzig now has a separate plumbing service to provide the annual servicing of the hot water heater and to check things out in general. This was a much better experience versus having an HVAC tech trying to do the preventive maintenance for plumbing.

We've had experts from HVAC, plumbing, and electrical to service and inspect our new home, and all members have gone above and beyond in their educating us as homeowners while also providing practical solutions. Of particular note, Johnny Baker installed a HALO 5 water filtration system and was extremely personable, friendly, knowledgeable, approachable, and all around friendly! Thank you so much, Welzig!

We’ve been using Welzig for many, many years. They always have excellent service and very knowledgeable, friendly, and timely folks working on whatever issue we have. They helped our sad furnace limp along for years until we were ready to buy a new system, and I am glad I do the yearly maintenance on our water heater, since we have a ton of iron and minerals in our well water.
