💨 41.2% duct leakage down to just 2.3%!

We recently completed a single-zone Aeroseal duct sealing on this home, and the results were pretty impressive.

Before Aeroseal, the supply duct system was leaking 576.9 CFM, or 41.2% of the system's airflow, before that air reached where it was intended to go.

After Aeroseal? 31.9 CFM and only 2.3% leakage.

In most homes around Bismarck, that leaking air isn't necessarily leaving the house. It's ending up in places it wasn't intended to go—wall cavities, floor and ceiling cavities, mechanical spaces, and other areas—rather than being delivered through the registers where you actually want it.

That's what makes Aeroseal so effective. It seals those hard-to-reach leaks from inside the ductwork without having to tear into walls and ceilings.

✅ Better airflow
✅ More even temperatures
✅ Improved comfort
✅ Less wasted heating and cooling

Your furnace and A/C are already doing the work. Let's make sure the air gets where it's supposed to go.

This old A/C had definitely seen better days. After years of keeping the house cool, it was time to retire it and install a brand-new Bryant system that's ready for many more North Dakota summers. ☀️

Nothing beats seeing a clean install and knowing the homeowner won't have to worry about their A/C giving up when it's 95° outside.

We've got some hot weather on the way!
If you've been crossing your fingers every time your A/C kicks on... it might be time to see what your options are. 😅

The good news? Estimates are always FREE, and there's no pressure—just honest advice to help you decide what's best for your home.

One small favor—we know everyone wants to be cool when the temperatures climb. 😅 Please be patient with our team over the next couple of weeks. We're working long days to get everyone taken care of as quickly as we can, and we truly appreciate your support.

Give us a call before your A/C decides to take a summer vacation! ☀️😂

One home. Two duct systems. Incredible results.

We recently completed an Aeroseal duct sealing project on a 3,000 sq. ft. home with separate **upper-level and basement duct systems**.

🏠 **Upper Level**
• Started with **870 CFM** of duct leakage
• More than **54%** of the system's airflow was being lost
• Reduced to just **42.7 CFM** after Aeroseal
• System efficiency improved from **45.6% to 97.3%**

🏠 **Basement**
• Started with **162 CFM** of duct leakage
• Reduced to just **9.7 CFM** after Aeroseal
• System efficiency improved from **89.8% to 99.4%**

These are the kinds of results homeowners can feel every day:
✅ More even temperatures between floors
✅ Better airflow to every room
✅ Less energy wasted through hidden duct leaks
✅ Improved comfort and indoor air quality

If some rooms in your home are always too hot or too cold, your ductwork—not your HVAC equipment—could be the problem.

Interested in learning if Aeroseal is right for your home? Give **Northern Plains Heating & Air** a call at **701-222-2155**. We'd be happy to answer your questions and see if duct sealing is the right solution for you.

🌬️ Quick HVAC Tip for the Week

If your filter looks anything like this, it's time for a replacement!

Your furnace filter doesn't just work during the winter. It protects your A/C system all summer long by keeping dust and debris out of the equipment.

A simple filter change can help your system run more efficiently and keep your home comfortable during the hottest days of the year.

Not sure what size filter you need? Give us a call—we're happy to help.

How old is your furnace? 🤔

This Lennox system had been heating this home for many years, but age was catching up with it. Our team replaced it with a new Bryant high-efficiency furnace, upgraded the filtration system, and added whole-home humidity control.

The transformation speaks for itself. Swipe through the photos to see the before and after!

When you invest in a new heating system, you're investing in:
🔥 Comfort
💰 Efficiency
🌬 Cleaner air
🏠 Reliability

Thinking about upgrading your system? We'd be happy to help.

If your rooftop unit is constantly needing repairs, making noise, or struggling to keep up… it might be time.

We recently installed these new commercial rooftop systems in Bismarck to help improve comfort, reliability, and efficiency for the building. No patchwork fixes — just brand new equipment done right.

Summer’s coming fast, and once the heat hits, emergency replacements get a whole lot harder to schedule. Planning ahead saves headaches.
