Welzig Heating & AirHVAC Services in Longmont

Staff and technicians were great to work with. Very satisfied.

We have depended on Welzig for many years over multiple properties, and their services are always outstanding! Michael Moorhead is wonderful to work with and always provides prompt, fair estimates for HVAC needs, and James Miltersen does an outstanding job leading the installation team. This is such a great company!

Working with Casey Welzig on the bid was seamless, and it was a breeze finishing up the details with Cassy Welzig. The installation team James and Juan did great work. Love the attention to detail.

Very knowledgeable. VERY helpful and careful in our home. Great at explaining how to use the system.

Our AC installation involved some unexpected complexities, but the work crew stayed well past regular work hours to insure a successful installation and make sure everything was working correctly.

Having a company that we have trusted with our maintenance for years on two homes really helps when it's time to make a big purchase like installing a new furnace. We were given options and careful explanations. We trusted their experience and expertise.

My unit was installed without my being present as I was out of town, no problems.

Very professional

Answered all of my questions and met my requests.

Fast and Friendly Service

Questions were answered in a clear manner. Everyone we encountered during process was knowledgeable and considerate! We will continue to work with the Welzig team for our HVAC needs.

the installation was professionally with obvious expertise. I also greatly appreciated that they rearranged their schedule to accommodate my requirements.

We have been Welzig Heating \& Air clients for 20 years. They are simply the best we have ever used.

James and Jimmy did an outstanding job of installing my new Bryant AC unit. Very professional and took me through everything that was done by them with installation. Highly recommend Welzig.

Great customer experience and professional

Our technicians at Welzig were great! They showed up on time, let me know exactly what was going to happen for the installation and when their electrician would come. Once they were done, they did a great job cleaning up before showing us everything we needed to know about our new system.

Wilzig was amazing , caring and understanding about\-what I needed from Customer service to the Technicians that installed everything I will definitely refer them they do marvelous work ! I have tried other Companies to service things but by far Wilzig is the best! Sticking with them now!

No high pressure sales.

Positive experience with instillation of AC heat pump. Provided guidance on its operation.

Great

Our house is nearly 75 years old and has never had air conditioning. In addition, Welzig vented the dryer to the outside for us. I think installation involved many challenges. We are very happy with their work and found it very easy having their installers at the house.

Welzig has been excellent from start to finish

5 star Dealer. Great experience for us. Have used for service on old system. Neighbors originally recommended and so do we

The Welzig family of sales, office, and installation professionals have been wonderful to work with for our heating and cooling product purchase. They were patient as we worked through what we thought would be a challenging and complex mini\-split design. Welzig coordinated and excelled in every aspect of the project. Thank you for your expertise and enjoyable team.

Didn't understand why the installation was scheduled for a Friday and a Monday. Weather wise it worked out okay. The attributes should all be the highest mark.

The service provided by Welzig Heating has always been timely, efficient, and high quality. The technicians have been courteous and knowledgeable.

Responsive

Impeccable service and workmanship

Techs are well trained, courteous, diligent, and well organized.

They did a great job and made sure we understood how to use our new heaters and air conditioners

Saul and Max were great. They had to cut an old furnace apart and pull it out of an attic. The Bryant installation we off without a hitch and remained on time even though the removal of the old furnace was so challenging. When they were done we couldn't even tell that anyone had been there; awesome!

The Technicians were very helpful and did a great job!

Welzig is an honest, affordable company you can trust to diagnose, repair/replace and follow up for all your HVAC needs.

I am confident in trusting Welzig Heating \& Air with all my HVAC needs. They are a considerate and high quality company.

Fast, courteous, affordable

They put in a new water about a year ago and same excellent service.

A great experience.

Walked us through the 6 different quotes. Very thorough and friendly.

Everybody was so helpful

Excellent workmanship, work done was very professional and quick.

Bryant is professionally thorough in their evaluation of existing systems and required retrofitting to maximize the system's performance

Been a customer for as long as I've been a home owner. They have never been less than everything ive needed.

Our furnace and AC are both from Bryant. Having this additional unit makes sleeping easier in the heat of the summer! Yay!

Casey showed us several combinations and options for replacing our current equipment. He was extremely knowledgeable and answered all our questions about efficiencies, reliability and installation. He explained pros and cons of each option. Our install team was wonderful, too. Eric and Guillermo were prompt and friendly. They got to work quickly and willingly endured our interruptions to answer questions. They cleaned up everything each day before they left. They also handled an unexpected problem that arose with grace and patience in addition to patiently explaining how to use/set the thermostat that controls our brand new super\-dooper HVAC system.

Welzig?s employees demonstrated excellent knowledge, troubleshooting skills, and customer service while evaluating my HVAC system, issues, and options. The quality of the new installation was superb.

Welzig employees are always a pleasure to work with

Initially, Weston came to our house to check our 18 year old air conditioner, which we suspected was not functioning properly. He diagnosed the old unit and determined that it was at the end of it's life. He offered to get it running again in an effort to finish out the cooling season but reminded us that it would only be a band aid fix. We decided to install a new unit. Saul and Eric installed the new air conditioner for us. They were professional, courteous and knowledgeable. When I had questions they took the time to answer my questions. The installation went off without a hitch and they cleaned up the work area completely. I would not hesitate to have these two gentlemen work on my HVAC system again. Incidentally, Saul has been here before, having installed our new furnace a few years ago. We have been using Welzig for many years and appreciate their prompt and professional service.

Went with Welzig after investigating a number of other companies. They had by far the best communication, and were willing to answer my (many many) questions, as well as provide a number of quotes. When doing the estimate, they noted there would probably be some drywall repair that was needed after the installation due to the configuration of our furnace, but during the installation they managed to figure out how to do it without requiring any post\-installation repair, saving us some extra $. Have been VERY happy with our experience with them so far, and look forward to a continued relationship with them for the foreseeable future.

Edgar, Saul, \& Robert removed our 28\-year old furnace \& installed a new Evolution unit yesterday; they completed the work in one day, \& did a fabulous job ... much appreciated!

We have done business with Welzig for 25 years. They are consistently honest, competent and reliable.

Welzig's installed our new Bryant furnace, thermostat and humidifier 3/2/18. We are delighted with the quality and appearance of of the installation. About a week after the installation, Welzig's sent someone to evaluate the installation, correct a couple of minor issues and answer our questions.

My installation day turned out to be about 5 degrees outside and snowing, but the Welzig crew showed up on time despite the driving conditions and with nary a grumble or frown they got the work done inside and out. My home is older and they ran into unexpected issues needing re\-piping of vents and air con. These problems were resolved. Each and every member was friendly and professional and they all worked very hard. When the work was done, David explained how the new furnace worked and what type filter I should use. I have only been using the furnace for a few days but it seems quiet and working properly and efficiently. I also appreciated the Welzig company accommodating my schedule. The only comment I have as far as improvement is the fact that new furnaces put out nitric acid waste that must go to a drain. As this can corrode drain covers and pipes and is not good for my septic tank I think the condensate filters that are available should be part of installation unless the owner does not want them. They will be coming back to put one in for me at a minimal extra charge. Overall, a job well done!

Home furnace replacement

Awesome!

Rate service

So far the equipment has been good. The furthest bedroom from the unit is not getting as warm as the rest of the house. The furnace may not have the power needed to get the air that far. Some minor concerns from the installation \- didn't light water heater pilot before leaving, scratched my wood door, left crawl space access lid open, and cut big holes in wall for thermostat wires. They did fix the wall though.

Welzig Heating \& Air was professional all the way from the first phone call up into the final day of the install. They answered all my questions after the install. No doubt their service will be the same . Highly recomend them.

The people at Welzig Heating and Air were friendly and informed and treated me very fairly. It was a pleasure to work with them. I would highly recommend it this company.

Very pleased with the service and emloyees. System is working great.
