Although Welzig was not able to complete the specific service I requested because of the unusual set up of my HVAC system, they were very honest about it up front. As such I would not hesitate to use them for other HVAC services when the need might arise in the future

We have used Welzig since 2008 for a new boiler, routine maintenance, and any necessary HVAC repairs. Scheduling has always been prompt, the service techs knowledgeable, and they are willing to explain issues and costs clearly. Recently our boiler was inoperable and within 3 hours Chris K arrived, checked, checked the system, and was able to track down a broken electrical wire. He was efficient, explained the problem, noted any additional costs beyond the basic service call, and gave recommendations for any other service needs. Excellent service tech. Thanks, Chris

Marcy moved-up our emergency furnace replacement to get it done the day before a big snowstorm instead of the original schedule for the day after. Saul and Edgar worked extra hours to get a complex job done in one day. Very happy that we went with Welzig.

Welzig just installed a new side arm water heater. They arrived on time, did the job in a very professional manner. Technicians were very friendly and answered all our questions. Names were Juan and Edgar were our technicians.

Very pleased with Westons explanation of our boiler problem.He was also very helpful in addressing our old water heater. He advised us of options, gave up exact quotes and made a on the spot appointment for replacement. He arrived on time, did not rush us and was very polite. A really nice young, professional man. This has been our past experience with Welzig over the years. A really good company.

I am glad I chose your company to help with my air conditioner problem. I was a bit surprised when your workers discovered that the old duct-work was only four inches in diameter, actually, I was more depressed and concerned about how this would affect the entire job.

Your crew proved themselves to be the professionals and tackled the job with vigor and diligence, giving me the confidence to know that the job would be handled correctly. I had no reason to worry.

The way they work together is amazing and should be a role model for others to follow. The attention to detail and their wanting me to be informed and involved in what needs to be done is most respectful.

I know the job will not be completed until tomorrow, but I felt it necessary to pass on to you my observations and let you know that I am pleased with what I see being accomplished.

Thank you,
Bob Conner

Juan, Saul, and Edgar “kicked ass”…. they were very hard workers, professional and respectful. They left the work area cleaner than they found it.

You have a great crew and the furnace is cool.

Wanted you to know how appreciative we are of your fast response time and friendly customer service. Especially Mike and Mary. The last company we used was terrible, each time they came out I cringed when I opened the door. They were never friendly. We were going to use another company that the owner of the company used for his home but they were booked out for weeks. (we are one of the few companies that offer same day emergency service.) We’re excited to continue using you for all our heating and cooling needs.

Team Welzig,

Thank you for the professional and friendly service we recently received from your team members.

Two years ago, your company replaced our dated furnace and we were very pleased with the service and expertise of your employees. Juan and his team did an outstanding job installing all new plumbing for the hot water heat system.

This year we decided to add air-conditioning to our home, and again called Welzig Heating & Air. Casey and Dave responded with the information we needed to make our decision on the new system. Due to the hot water heating method of our home, all new duct work was necessary. And, to our delight, Juan and his crew were once again ready for the challenge.

We are very pleased with our new heating and air-conditioning systems. Thanks again, Team Welzig!

We recently had Welzig do furnace maintenance and duct cleaning at our new home in Loveland.

We couldn’t ask for a more professional service.

Chris & Tom were both exceptional. They both are very good at what they do, answered all our questions, and were fun to talk to. We will certainly use and recommend Welzig for future services.

… I was thoroughly thrilled with Saul and Jason’s professionalism. Jason came in and he was able to troubleshoot the problem. I have had a chemical burn in my respiratory system and when I called in I was almost in tears because I didn’t want to get sick again. When I called Marcy was excellent. It sounded like there really wasn’t a space for me today but she fit me in and I couldn’t be happier. Saul was so thorough and I am so pleased with the overall work ethic that I saw. Thank you, thank you, thank you!”

You all at Welzig must have the monopolistic corner on the market for courteous, capable young people – who are genuine pleasures to meet in a territory where their presence sadly seems increasingly infrequent! Weston was a delight just to chat with, as every Welzig employee I have met has been. I could not observe his work, as I am woefully crippled and likely will never again see my basement; however, I had no uncertainty whatsoever that my “supervision” was not at all needed in the furnace room!

Your exceptional people make it easy to select, trust, and freely recommend a service company. I happily and confidently extend that to – and for – Welzig at every opportunity.

I just hope you can enjoy an “accident-free” holiday season from now on – and that it extends well into 2015! Your folks are just too important and talented to be shelved with the wounded warrior crowd!
