Water Treatment Services in the Boulder Area

Most people believe that water filtration systems are only suitable for areas without a municipal water supply. This is simply not true. Even though municipal water is treated, the treatment may not be sufficient to remove minerals from hard water, resulting in problems with the municipal piping system or the main water pipe to your home. The bottom line? Water filtration systems can be a great asset for any household, so if you have concerns about your water, contact Welzig Heating and Air and learn what a water filtration system can do for you.

It is important to protect appliances that use water by utilizing a whole-house water filtration system. When you install a whole home system, all of the water entering your home will be filtered, so you will be safeguarded in the event that a main water pipe breaks or other problems arise. Every drop of water from every faucet in the house is filtered by a whole-house water filtration system. Water filtration systems remove minerals from water, making it softer and more suitable for washing clothing.

They Speak For Us

Dave Kaplan-Gomez and James Miltersen installed my new Tankless Water Heater. Both were polite and professional. Care was taken not to damage anything in my house which I really appreciated. I use Welzig for all my HVAC needs and highly recommend them.


Our 23-year-old A/C system ran out of “borrowed time” and became too difficult to continue maintaining. With great advice from Casey Welzig,, we replaced the old system with a Bryant Evolution A/C system. Max Loustaunau and Seth Bernhardt did an excellent job with removing the old system and installing the new one. Both of them are great to work with — very professional and very personable. We are really amazed at how much better the new system works!


Bob came out to look at our swamp cooler and was remarkably helpful and professional. Not only did he give me a knowledgeable diagnosis, but he also taught me a lot in the process. We’ll be calling him for all future needs with our cooling system.
