Ductless HVAC systems—also called mini-splits—are becoming a go-to option for Minnesota homeowners looking to cut energy bills without cutting corners on comfort. Whether you’re finishing a basement, updating a sunroom, or just tired of uneven temps, ductless could be your answer.
​
Let’s break down how these systems work and why they’re winning over more homes each year.

How Ductless Systems Work
Unlike traditional systems that push air through ducts, ductless systems move heat directly to or from a room using a small indoor unit connected to an outdoor compressor. Each unit controls the temperature for its specific zone—meaning less energy waste and more targeted comfort.

Why They’re Energy Efficient

• No duct losses: Traditional systems can lose up to 30% of energy through leaky ducts. Ductless skips that entirely.
• Zoned heating & cooling: Only heat or cool the spaces you use—when you use them.
• Inverter technology: Many ductless models adjust speeds rather than cycle on/off, using less power overall.

These features add up to lower monthly energy bills, especially during peak heating and cooling seasons in Minnesota.

Cost Savings Over TimeWhile installation costs vary, many homeowners find ductless systems pay for themselves in 3–5 years through:

• Lower energy bills
• Reduced maintenance needs
• Longer equipment life
• Utility rebates and tax incentives (ask about current Xcel and CenterPoint programs!)

And if you’re using window units or electric baseboard heat? You’ll feel the difference right away—both in comfort and on your next bill.

Perfect for Specific SpacesDuctless shines in:

• Bonus rooms
• Garages or workshops
• Older homes without ducts
• Finished basements
• Home offices or additions

If there’s a room that never quite gets comfortable, this could be your fix.

Summer in Minnesota can be beautiful—but also brutally hot and humid. Whether you're in the Twin Cities, Duluth, or out in Greater Minnesota, your HVAC system works overtime to keep your home comfortable. But cooling your home efficiently isn’t just about cranking the AC. It’s about working with the system you have, maintaining it smartly, and using a few community-tested tricks to keep your space cool without burning a hole in your wallet.

Here’s how to stay cool and stress-free this summer—with HVAC strategies that work in Minnesota’s unique climate.

1. Schedule a Seasonal HVAC Tune-Up 
Your HVAC system might’ve hibernated through a long winter, but Minnesota summers demand just as much attention. Schedule an HVAC check-up in late spring to:

• Ensure your system is running efficiently before peak heat
• Catch worn-out parts before they fail
• Prevent mid-summer breakdowns 

Local tip: In Minnesota, humidity can be just as punishing as heat. Ask your technician to check your system’s dehumidifying performance, too.

​
2. Optimize Your Thermostat for Minnesota’s Temperature Swings
Summer days can hit 90°F while evenings cool off. A programmable or smart thermostat helps manage these fluctuations automatically.

Try setting:

• 78°F when you’re home
• 85°F when you’re away
• 72–74°F for sleeping comfort 

Many Minnesota utilities offer rebates for installing smart thermostats—check with Xcel Energy or Minnesota Power.


3. Change Your Filters—Especially if You’ve Got Allergies or Pets
In a state where spring pollen meets summer dust and dander, air filters clog quickly. Change them every 1–2 months in summer to keep air flowing freely and reduce allergens.

If you live in a rural or lake area with more open windows and dust, check filters even more frequently.


4. Seal Air Leaks for Maximum Efficiency
Minnesota homes, especially older ones, are notorious for air leaks around windows, doors, and basements. Don’t let that cool air escape! Weather-stripping, caulking, and even thermal curtains can reduce the strain on your AC.

Community tip: Ask your city or utility provider about home energy audits—many Minnesota communities offer them free or at a discount.


5. Keep Outdoor Units Clear from Debris 
By June, your outdoor condenser may be covered in cottonwood fluff, maple seeds, or overgrown shrubs. A quick cleanup can improve performance and prevent overheating.

• Trim vegetation within 2 feet
• Rinse coils with a hose (gently!)
• Clear off pollen buildup from nearby trees
  
  
  

6. Run Ceiling Fans the Right Way
Ceiling fans can make your home feel 4–6 degrees cooler—but only if they’re spinning counterclockwise in summer. This creates a breeze that complements your AC.
​

7. Plan Your Chores Around the Heat
Ovens, dryers, and dishwashers give off heat that competes with your AC. During Minnesota's warmest months (July and August), run major appliances in the early morning or late evening.


8. Upgrade If Your HVAC System Is Over 12 Years Old
Minnesota’s extreme seasonal shifts take a toll on HVAC systems. If yours is over 12–15 years old, it may be time to upgrade to a more energy-efficient model.

If your air conditioner is struggling to keep up—or not working at all—it might be time for a replacement. But let’s be honest: replacing your AC unit isn’t pocket change. It’s an investment in year-round comfort, energy savings, and peace of mind.

Here’s what Minnesota homeowners need to know about what it costs, how to pay for it, and why planning ahead can save you serious stress (and sweat).

How Much Does a New AC Unit Cost in Minnesota?
The cost of replacing a central air conditioner varies, depending on system size, efficiency rating (SEER2), and installation complexity. On average:

• Basic replacement systems: $4,500–$6,500
• Mid-efficiency systems: $6,500–$8,500
• High-efficiency or heat pump systems: $8,500–$12,000+

Factors that can affect your price:

• Home size and layout
• Ductwork condition or modifications needed
• Brand and SEER2 rating
• Permit and code requirements in your city

Pro tip: If your furnace is also older, you may qualify for rebates or savings by replacing both systems together (combo installs often lower labor costs).


Financing Options for Your New AC
Don’t let upfront costs stop you from getting the comfort you need. Many Minnesota homeowners are choosing flexible financing to spread the cost over time—with manageable payments and often 0% interest promotional periods.

Popular HVAC financing options include:

• Manufacturer-sponsored financing (Trane, Luxaire, and Reheem)
• Third-party lenders like Greensky or Synchrony
• Local utility rebates with financing tie-ins (check Xcel or CenterPoint Energy programs)

Why Financing Makes Sense

• No big upfront payment
• Keeps cash flow flexible for other home needs
• Often includes service plans or extended warranties
• Get a better system today, not a band-aid repair

In a Minnesota summer, waiting too long on a failing system can cost you more in emergency repairs, high energy bills, or even water damage from freeze-ups.

Is It Time to Replace?It might be, if your current system:

• Is 10–15+ years old
• Needs frequent repairs
• Isn’t cooling evenly or efficiently
• Still uses R-22 refrigerant or struggles with leaks
• Drives up your energy bill each month

Refrigerant may be invisible, but the impact it has on your home comfort—and the environment—is crystal clear.

Minnesota homeowners continue to upgrade ACs and heat pumps, a new question is popping up:

What’s going on with refrigerants, and how will it affect my system?
Let’s break it down.

What Is Refrigerant—and Why Is It Changing?
Refrigerant is the chemical inside your AC or heat pump that makes cooling possible. It absorbs indoor heat and dumps it outside—keeping your home comfortable.

Older refrigerants like R-22 (Freon) were phased out due to environmental harm. The current go-to, R-410A, is now on the chopping block too, thanks to its high global warming potential (GWP).

Key Dates Minnesota Homeowners Should Know

• 2020: R-22 banned for production/import in the U.S.
• 2025: R-410A starts phasing out under the AIM Act
• 2036 goal: 85% national reduction in HFCs like R-410A

If your system still uses R-22, it’s well past time to upgrade. If you’re on R-410A, your next replacement may use something even better.

What Are the New Refrigerants?
The HVAC industry is moving toward low-GWP refrigerants that are kinder to the environment and still highly efficient. Leading options include:

• R-32: Already popular globally; more efficient and lower GWP than R-410A
• R-454B: A rising star in U.S. systems; expected to be the primary R-410A replacement
• CO₂-based systems and other naturals: Gaining traction in niche high-efficiency markets

These refrigerants are safer for the planet and keep your home just as cool.

What Does This Mean for My AC or Heat Pump?If your system uses R-410A and is working fine, you’re okay for now—but it’s smart to plan ahead. Here’s what to keep in mind:

• Older units = harder to service. Prices for phased-out refrigerants spike as supply drops.
• Repairs may cost more. A leak in an R-410A system a few years from now could mean replacing the whole unit.
• New installs will use new refrigerants. Starting in 2025, most new systems will transition to R-32 or R-454B.

How to Prepare as a Minnesota Homeowner

• Schedule a pre-season checkup to assess your refrigerant and system status
• Talk to your HVAC provider about upgrade timelines and rebate options
• Plan for your next system with eco-friendly refrigerants in mind

The Bottom Line

Refrigerant phase-outs might sound technical, but they’re really about protecting your home comfort and the planet. Planning ahead ensures you avoid future repair surprises, stay compliant with regulations, and cool your home responsibly.

If you're thinking about replacing your air conditioner or heat pump, you’ve likely heard the term SEER—and more recently, SEER2. These ratings help homeowners understand how efficient an HVAC system is—but the 2025 standards mean things have changed.

Here’s what Minnesota homeowners need to know about SEER, SEER2, and how it impacts your next upgrade.

⚙️ What Is SEER?
SEER (Seasonal Energy Efficiency Ratio) measures how much cooling a system provides per unit of electricity used. The higher the SEER, the more efficient the unit.
Example:

• A 14 SEER unit uses more energy to cool your home than a 16 SEER unit over the same time period.

⚙️ What Is SEER2?
As of 2023–2025, the DOE (Department of Energy) introduced SEER2 to more accurately reflect real-world conditions. It uses updated testing procedures with higher external static pressure—meaning the ratings now better represent how systems actually perform in homes.

• SEER2 values are slightly lower than SEER for the same system, but they’re more realistic.
• For Minnesota, the minimum SEER2 for new installs is 13.4 SEER2 (which replaces the older 14 SEER minimum).

🔍 Why It Matters

• Higher SEER = lower energy bills. Upgrading from a 10 SEER to a 16 SEER2 unit could save hundreds each year.
• More accurate efficiency. SEER2 helps homeowners and contractors compare systems more fairly.
• Rebate eligibility. Most utility rebates (like Xcel Energy or CenterPoint) require a specific SEER2 rating to qualify.

✅ Choosing the Right SEER2 Rating for Your Home

• 13.4 SEER2 is the minimum for code compliance.
• 14.3+ SEER2 units often qualify for rebates.
• 16–18+ SEER2 models deliver the highest efficiency and comfort—ideal for long-term savings.

🏡 Is It Worth Upgrading Now?
​Yes—especially if your system is:

• 10+ years old
• Constantly needing repairs
• Causing uneven temps or high energy bills

We’ll help you compare models, understand rebate options, and choose the best fit for your home.

Minnesota weather doesn’t mess around—so why should your heating and cooling system?

If you're looking for year-round comfort and energy efficiency, a dual fuel system might be the perfect match. These smart setups combine the best of both worlds: the energy-saving efficiency of a heat pump, and the powerful backup of a gas furnace when winter really kicks in.
Here’s what homeowners need to know.

🔄 What Is a Dual Fuel HVAC System?
A dual fuel system (also called a hybrid HVAC system) uses:

• An electric heat pump to cool in the summer and heat during mild temps
• A gas furnace as backup heat when outdoor temps drop too low for the heat pump to run efficiently

Your thermostat automatically switches between systems based on outdoor temperature—no guessing, no toggling required.

✅ Why Consider Dual Fuel in Minnesota?

• Efficient in mild weather: The heat pump handles fall, spring, and even much of winter—cutting fuel use and lowering bills.
• Reliable in deep cold: When temps drop below 20°F (or lower), the gas furnace kicks in for stronger, faster heat.
• Reduced emissions: You burn less fossil fuel throughout the year—especially if your electricity comes from renewables.
• Rebate eligible: Many utilities (like Xcel Energy and CenterPoint Energy) offer incentives for dual fuel or high-efficiency heat pump installs.

🏡 Is Dual Fuel Right for Your Home?
Consider a dual fuel system if:

• You’re replacing an older furnace and AC
• You want to reduce your reliance on fossil fuels but need reliable cold-climate performance
• You’re interested in long-term savings and comfort upgrades
• Your home has—or could add—ductwork

If you already have a furnace and central AC, you may only need to upgrade your AC to a compatible heat pump.

Let’s Talk Hybrid Comfort
Dual fuel systems are a great option for Minnesota homes that need both brains and brawn when it comes to heating and cooling. We’ll help you design a setup that fits your home, budget, and comfort goals—without wasting energy.

When it’s time to replace your cooling system, many Minnesota homeowners ask:

Should I install a heat pump or central air?

Both systems can keep your home comfortable during the summer—but how they work (and what they offer) is quite different. Here’s a side-by-side breakdown to help you make a confident choice based on your home, comfort goals, and long-term energy savings.

❄️ What’s the Difference?

Summer brings family cookouts, cabin weekends… and unfortunately, a spike in HVAC service calls. The transition from spring to summer puts your air conditioning system to the test, and if something’s off, it usually shows up just as the temps soar.

Here are the most common HVAC problems homeowners face heading into summer—and what to do before a small issue turns into a full breakdown.

​
❌ 1. Warm Air from the Vents
If your AC is running but blowing warm or room-temp air, it could be:

• Low refrigerant levels
• A dirty evaporator coil
• A clogged air filter
• Thermostat settings out of sync

✅ Quick Fix: Check your filter and thermostat settings. If that doesn’t solve it, call for a refrigerant and coil check.


❌ 2. Weak or Inconsistent Airflow
Rooms feeling uneven? Air barely making it through vents?

• Dirty filter
• Blocked ductwork
• Failing blower motor
• Leaky ducts

✅ Quick Fix: Start with the air filter, and ensure vents aren’t blocked by furniture. A blower motor check may require a technician.


❌ 3. Unusual Noises or Vibrations
Banging, buzzing, or rattling can point to:

• Loose components

✅ Quick Fix: A professional can test humidity levels, inspect refrigerant charge, and evaluate airflow balance.


🛠️ Pro Tip: Most Issues Can Be Prevented
A seasonal tune-up helps catch small problems early. Plus, Xcel Energy and CenterPoint often offer rebates for preventive service with licensed techs.


☀️ Stay Cool, Stay Ahead
The best time to handle HVAC problems is before they become emergencies. Whether it's weak airflow or warm air on a 90° day, we’re here to keep your system running strong all summer.

As temperatures climb and AC units switch into high gear, it’s the perfect time to take a few simple steps to save energy—without sacrificing comfort. Early summer is ideal for prepping your home before peak heat hits, and a few smart changes now can reduce your energy bills all season long.

Here’s how to keep your home cool, efficient, and budget-friendly through early summer and beyond.

1. Raise Your Thermostat (Just a Bit)
Setting your thermostat a few degrees higher can significantly reduce cooling costs.
📌 Try 76–78°F when you're home, and even higher when you’re away.
A smart thermostat can automate these changes and adjust to your schedule.

2. Use Ceiling Fans to Assist Cooling
Fans don’t lower room temperature, but they do help you feel cooler.
Run them counterclockwise in summer to push cool air down and reduce the need for constant AC use.

3. Close Curtains and Blinds Midday
Sunlight = heat gain. Keep curtains or shades closed during the hottest part of the day to block radiant heat—especially on south- and west-facing windows.

4. Change Your HVAC Filter
A clogged filter makes your AC work harder.
📌 Replace every 1–3 months to maintain airflow and efficiency.

5. Schedule a Summer AC Tune-Up
Prevent mid-season breakdowns and improve energy performance by having a pro check:

• Refrigerant levels
• Coil condition
• Airflow and system pressure
• Thermostat calibration

Rebates may be available from Xcel Energy and CenterPoint when performed by a licensed HVAC tech.

6. Unplug or Power-Down Heat-Producing Electronics
​TVs, computers, and appliances add heat to your space—even in standby mode. Unplug what you’re not using, or use smart strips to shut down devices all at once.
