Window Cleaning
Crystal-clear results inside and out. Residential and commercial across Central Minnesota.
Family-Owned Since 2003
Eco-friendly window, carpet, air duct, and soft washing — serving Sartell and St. Cloud since 2003.
We use Air Whips — NADCA recommended.
When comparing duct cleaning companies, you may not realize you're comparing two completely different methods. Here's what you need to know.
Our air whip machine vacuums at 2,000 cubic feet per minute (CFM). Brush-based systems top out at 300 CFM — nearly 7× less powerful. More suction means far more dust, dander, pollen, mold, and mildew removed.
Air whips remove large construction debris, plaster, and more. Brush-based systems have a small nozzle — large objects block their vacuum entirely.
Many homes have zone-control dampers inside ductwork. Air whips work right through them. Brush-based systems cannot pass dampers at all.
Our air sweep and brush are under 1 inch in diameter — handles any duct size or turn. Brush-based 3-inch heads get stuck in smaller ductwork.
Air whips clean the trunklines and plenums — the distribution backbone of your HVAC. Brush-based cleaning creates no negative pressure and cannot clean these critical areas.
We connect the air whip machine to your ductwork or plenum, putting the system under negative pressure. Air whips dislodge contaminants throughout the system, which are vacuumed into sealed containers. Heavy particles are swept toward the vacuum using air scrubbing tools. We clean the entire HVAC system — and we clean your vent covers too.
"Air whip cleaning is the most comprehensive method —
and it's the only one we use."

Natural Cleaning
Most cleaning companies use harsh chemicals that linger in your air long after the job is done. We take a different approach — our indoor services (carpet, upholstery, rug, and air duct cleaning) use Young Living Thieves Cleaner, a plant-based blend of natural essential oils. For windows and screens, we use an environmentally friendly soap.
It's better for the environment, your kids, your pets, and your family's long-term health. That's what it means to be your natural choice.

About Four Seasons
Four Seasons was built on one idea: your home deserves to be cleaned the right way — by people who actually care, using products that won't harm your family.
Since 2003, Matt and Carolyn Bertsch have been showing up for Sartell and the greater St. Cloud community — not just as cleaners, but as neighbors. Carolyn served on the St. Cloud Salvation Army advisory board and volunteered at their food shelf every Thursday for years. The team has run food drives for Celebration Lutheran Church in Sartell, collected donations for Promise Neighborhood in St. Cloud, and raised money for Homeless Helping Homeless. That team photo in the gallery? United Way Day of Caring — Four Seasons cleaned every window at the Central MN Sexual Assault Center, inside and out, free of charge.
When you call Four Seasons, you're not calling a franchise. You're calling the owners.

Common Questions
We use plant-based, chemical-free solutions built around Young Living Thieves Cleaner — a blend of cinnamon, clove, eucalyptus, rosemary, and lemon essential oils. Everything we bring into your home is safe for children, pets, and the environment. Why we use Thieves Cleaner →
Yes — commercial work is a big part of what we do. We clean windows, carpets, upholstery, and light commercial air ducts for offices, restaurants, retail stores, and more across Central Minnesota. We primarily work weekdays during normal business hours. See our commercial services page →
NADCA recommends inspecting every 3–5 years and cleaning as needed. The EPA takes a condition-based approach — they don't endorse a fixed schedule, but recommend cleaning when specific problems are present: mold, vermin, or excessive debris near vents. You may need it sooner if you notice increased dust buildup, musty or stale odors, worsening allergies or asthma symptoms, or rising heating and cooling bills. Other triggers: moving into a home with unknown history, recent remodeling or construction, pets that shed heavily, or visible mold/debris near vents. Homes in Minnesota with forced-air systems running most of the year tend to accumulate debris faster than average. Air exchanger maintenance guide → Wildfire smoke & your filters →

Yes — significantly. The air whip method puts your entire duct system under negative pressure using a machine that pulls 2,000 CFM, then agitates debris with air whips. Everything is vacuumed into sealed containers. Brush-based systems use a small spinning brush with a 300 CFM vacuum — about 7× less powerful — and cannot pass zone dampers, navigate sharp turns, or clean trunklines and plenums. NADCA (the National Air Duct Cleaners Association) recommends source-removal methods like air whips for a reason. It's not a comparable service. Full breakdown: Air Whips vs. Brush-Based Cleaning →
Window cleaning is often done for cosmetic reasons — but clean windows actually last longer. Glass looks flat but is porous, meaning tiny holes in the surface collect dirt, dust, pollen, and debris over time. Left uncleaned, those deposits etch and permanently damage the glass. Regular professional cleaning stretches the life of your windows and protects your investment.
One of the biggest culprits of window damage is hard minerals from ground water — sprayed onto glass repeatedly by misdirected sprinkler heads or wind-caught watering. Mineral deposits build up and leave a milky, hazy residue that regular cleaning can't touch. At that point, restoration is needed: professional-grade mineral removal, and sometimes paint scraping or sticker and adhesive removal. We handle both — cleaning to maintain, restoration to save.
In most cases, residential windows stay clean for about 3 months. Commercial windows — especially storefronts with heavy foot traffic — may need cleaning monthly or quarterly. That's one reason we work all four seasons, year-round, in any Minnesota weather. Many commercial clients set up a recurring schedule so it's one less thing to think about.

We clean the whole window — not just the glass. That means panes, frames, screens, sills, and tracks. Every window gets the same attention, whether it's your living room showpiece or the garage window. That said, not everyone wants the full treatment — we're happy to tailor the service to what makes sense for you.
Nope. Rain is pure water — it won't leave deposits on freshly cleaned glass. What dirties windows is airborne debris, pollen, and mineral buildup from sprinklers or hard water, not rain. A clean window after a rainstorm will look just as clear as before.
Once a year is a good baseline. Continued friction between carpet fibers and the dirt tracked in wears them down over time — professional hot water extraction removes what vacuuming can't. Some new carpet warranties actually require annual professional cleaning to stay valid.
We use hot water extraction — also called steam cleaning — which is the method recommended by carpet manufacturers. We inject a pressurized, heated cleaning solution deep into the carpet, push the dirt to the surface, and extract everything with a high-powered wet vacuum, leaving no residue behind.
Young Living Thieves Household Cleaner — the same plant-based solution we use throughout our services. It contains essential oils that are highly effective at killing germs and bacteria, and it's completely safe for kids and pets. Our goal is to leave your home not just cleaner, but healthier.

No. Residue left in carpet is a sign of incorrect cleaning — too much solution, not enough extraction power, or both. The cleaning solution matters, but so does the force behind it. Our equipment flushes and extracts thoroughly, so nothing gets left behind in the fibers.
Mostly power and knowledge. Rental machines don't have the extraction force of professional equipment — they can't pull as much dirt and bacteria out of the fibers, and they're more likely to leave moisture and residue behind. A professional knows the right amount of solution and water to apply for each job, and has the equipment to fully extract it. Less risk, better results.
Your carpets will be slightly damp when we finish — not wet, not squishy. Our high-powered extractor removes most of the moisture during cleaning. You can walk on them in socks right away, and they'll typically be fully dry within 6–12 hours. Running fans, a dehumidifier, or the air conditioning speeds that up.
Vacuum at least weekly — more often if you have pets. Regular vacuuming reduces the friction that wears down carpet fibers and extends the time between professional cleanings. Getting your air ducts cleaned every 3–5 years also makes a real difference: cleaner ducts mean less dust recirculating through the home and settling back onto your floors and furniture.
