Wildfire smoke isn't just an outdoor problem. It's inside your home and business too.

The last few summers, Minnesota's air quality has taken a hit — and smoke particles are small enough to sneak right through ordinary filters.

Your HVAC system can do more than heat and cool — with the right setup, it can:
✅ Filter out smoke and fine particles (MERV 13+ filters)
✅ Ventilate without wasting energy
✅ Reduce allergens, odors, and airborne germs

If your system isn't helping you breathe cleaner air, it's time for an upgrade.

📞 Message us to learn about IAQ solutions that actually work — before the next smoke wave rolls in.

Purchasing a new construction home is likely the biggest investment people make in their lifetimes. It is an exciting journey of selecting products that will be installed to make a new home yours. Many builders select the subcontractors to build your home based solely on price with little consideration to quality. And nothing sucks the excitement out of the process faster than not getting what you deserve when you move in to your home.

While equipment sizing is loosely enforced by local Code, other important parts your homes HVAC system are not. Consider the duct work that moves the conditioned air throughout your home. If it is not properly sized and installed you will end up with lackluster results. The main floor may be comfortable while the second floor is unbearably warm in the summer. The basement could be a meat locker when the AC is on. No one deserves to spend all that money on a new home and then live in a situation that is not exactly as they want it.

That is why here, at DNS, we design and install every HVAC system like it is our own home. We take great pride knowing that we are not taking shortcuts where other companies will. Even if it costs us some extra money to install it right, we will do the right thing for our builders and their clients. And our pride has results. In the over 500 systems we have installed in new homes we have returned to air balance only 13, a 2.5% rate. For reference it is estimated that 20-40% of new homes require further air balancing after the owners move in.

Unfortunately, most of your HVAC system lives within the finish walls and ceilings of your home. And while some minor issues are correctable after construction, there are many that are not. So, if you are considering purchasing a new home and want someone to check the HVAC system installation during construction, DNS is here for you. We are now offering HVAC installation assessments for home buyers purchasing a new construction home. Put yourself in the driver seat of the construction process and rest easy knowing that we are by your side assuring you are getting exactly what you deserve!
