When it comes to choosing a plumbing, heating, or air conditioning contractor to handle your home comfort needs, you have a lot of choices. So, why should you choose Dunn Plumbing, Heating & Air Conditioning, LLC?

Committed to Improving Your Energy Efficiency
At Dunn Plumbing, Heating & Air Conditioning, LLC, we understand a comfortable home means you and your family are happier, healthier, and more productive. This is why we have expanded our indoor comfort knowledge to include building science, not just general plumbing, heating, and cooling.
Studies prove that a plumbing and HVAC company that understand the whole home as a system better understands how to provide more comfort and more energy savings, making you happier all the way to the bank.
Unless a heating and cooling company understands the whole home, they may just think a bigger furnace or AC is the solution to your comfort problems. However, this is not always the case, as some rooms simply need better insulation, air sealing, or duct, redesign rather than an expensive new AC or furnace.
We will find the most cost-effective solution to solve your comfort problem and we won’t just simply try to sell you the solution that makes us the most money. The whole-home approach to comfort and energy savings is the best alternative.
For example, did you know:
- Typically, 80% of air leakage travels through 20% of the leaks. Find the 20% and seal them.
- Air traveling through insulation can reduce the R-Value (insulation value) by 75%.
- Attic ventilation can determine whether a house is comfortable or not.
- Many home comfort problems can be solved by simply air sealing, insulation, or duct modifications, rather than just putting in a bigger, more costly heating and cooling system.
