Accurate Duct Modifications

When you focus on the health, comfort, and efficiency of your home, you probably consider the furnace and air conditioner. Maybe you’ve included a whole-home humidifier, dehumidifier, or air purifier. Unless the ductwork operates properly, none of the equipment functions at its best. To achieve peak performance, Holt Plumbing & Heating, Inc. provides duct modifications in West Des Moines, IA and surrounding areas.

The ducts are the pathway of the conditioned air to every room in the home. When there are complaints with comfort, costs, funny smells, or an influx of air contaminants, very often the ductwork is to blame. Replacing the furnace or air conditioner won’t achieve your expectations if the duct system is poorly sized, damaged, ineffectively designed, or old.

Some common problems include:

  • Duct leaks that allow heated/cooled air to escape and force the system to work harder to achieve the desired temperature.
  • Incorrect sizing, whether too big or too small, is detrimental to optimum airflow and can result in uneven temperatures, longer run times, higher costs and greater wear and tear.
  • Installation errors are sometimes very visible in systems that twist in all different directions and tend to restrict airflow.

Correcting ductwork concerns provides a long list of benefits, including:

  • Cleaner indoor air quality
  • Consistent temperature throughout the home
  • Less wear and tear on system
  • Lower energy bills
  • Promotes greater HVAC efficiency
  • Reduced impact on the environment
  • Sufficient heating and cooling on all levels of the home
  • Superior moisture control
  • Quiet operation

The NATE-certified experts from Holt Plumbing & Heating, Inc. complete a variety of measurements to determine what you have, what you need, and what we can do to make sure the ductwork perfectly supports the furnace, air conditioner, air quality accessories, and your home. We consider the square footage of the residence, potential points of pressure loss, and any issues we encounter.

"I highly recommend Holt! I needed my water heater replaced, and they came out and took the time to discuss all of my options and to make sure that I fully understood everything about the project. They did quality work, with all of the plumbing in traditional copper. That was important to me because I didn't want any of that PEX in my home! My entire basement looks cleaner and tidier because of the work they did! I was also very impressed that they didn't talk down to me as a woman. I like to do my own appliance maintenance and repairs when possible, and they respected my desire to understand everything about the installation and the prospective maintenance into the future."


"We had never heard of Holt Heating and Plumbing until today. We had an emergency and needed service immediately and Holt was available. Israel was our technician and he was amazing! They will have our business for years to come! Thanks Israel and Holt!"


"Looking for a no fluff, no BS review of Holt? I got you... Over the past 15 years I've been a home owner, We've tried more companies that I could count. Lots of shady businesses out there... We were coming of a brand new HVAC installation just two years ago and the previous company completely botched it. It had problems within a month of installation and they were completely MIA. We ran it as long as we could to try and recoup the some cost, but it was a constant worry. Decided to give Holt a chance and we're so glad we did! Yes, they were more expensive, but it's the classic "you get what you pay for". 100% worth it! It's so hard to find a company that has the perfect mix of quality, punctuality, and honesty and Holt nails it. I genuinely appreciate their level of service and will pay a bit more to have someone I have the utmost confidence in doing the right thing. You should definitely give them a look if you need heating, cooling, or plumbing work."
