A swamp cooler, also known as an evaporative cooler, uses the natural process of evaporation to cool air. It pulls warm outside air through water-soaked pads, then blows the cooled air into your home. It’s an energy-efficient alternative to traditional air conditioning, especially in Spokane’s dry summer climate.
Signs your swamp cooler may need repair include warm or weak airflow, unusual noises, strange odors, or visible leaks. If your home isn’t cooling like it used to or your energy bills are climbing, it’s time to call Mainstream. Our licensed pros can quickly diagnose the issue and get your system back on track.
Swamp coolers need seasonal maintenance to run efficiently. This includes cleaning or replacing pads, flushing the water system, checking for mineral buildup, testing the motor and pump, and making sure the unit is sealed properly. Mainstream offers thorough tune-ups to keep your system reliable all season long.
Mainstream’s installation process starts with a free estimate and home assessment to ensure a swamp cooler is the right fit. Then, our trained technicians install the unit, connect water and electrical lines, and test everything for safe, efficient operation. We’ll walk you through how it works and answer any questions.
Swamp coolers offer an affordable, eco-friendly way to cool your home. They use less electricity than traditional air conditioners and add moisture to the air, which can help in dry climates like Spokane’s. Plus, they bring in fresh outdoor air instead of recycling indoor air, making your home feel breezy and comfortable.
In the dry, arid climate of Spokane and Northern Idaho, swamp coolers — also known as evaporative coolers — offer an efficient and affordable way to keep your home cool without breaking the bank. Unlike traditional air conditioning systems, swamp coolers use moisture to naturally cool the air, making them a smart choice for environmentally conscious homeowners and budget-minded families alike.
At Mainstream, we specialize in swamp cooler installation, repair, and maintenance. Our technicians are not only licensed and highly trained, but they’re also your neighbors — dedicated to treating your home with the same care and respect they’d show their own. Whether your current unit is underperforming or you’re interested in upgrading to a more efficient cooling solution, we’re here to help with honest recommendations and five-star service every step of the way.
Swamp coolers are ideal for homes in the Inland Northwest because they thrive in hot, dry conditions — just like our local climate. These systems:
Use up to 75% less energy than traditional central air conditioning
Circulate fresh, filtered air rather than recirculating the same indoor air
Add a bit of moisture to your home’s atmosphere, which can help prevent dryness and irritation during the summer
If you’re looking for a cost-effective and eco-friendly cooling system, swamp coolers are a solid solution — and Mainstream is the team you can trust to install, maintain, and repair them with precision and care.
When your swamp cooler isn’t working as it should, it can be frustrating — especially during the peak of summer. Our experts can quickly diagnose and resolve common issues like:
Insufficient airflow or poor cooling performance
Water leaks or dry pads
Electrical or thermostat malfunctions
Excess humidity or mold odors
Unusual noises or fan issues
We don’t just provide quick fixes — we get to the root of the problem to make sure your system runs efficiently and reliably all season long. If you suspect your cooler is underperforming, schedule a cooling system tune-up with Mainstream today.
If it’s time to replace your existing cooler or you’re exploring installation for the first time, our team will help you choose the right size and model for your home. We’ll walk you through your options and make sure your new swamp cooler is installed properly for optimal performance and longevity.
Not sure if a swamp cooler is the right fit? We’ll talk you through your alternatives — including central AC and ductless mini-splits — and help you make a decision based on your needs, budget, and home layout.
Just like any other home system, swamp coolers need routine maintenance to run their best. Our technicians provide seasonal inspections, pad replacements, water line checks, and fan cleanings to keep your cooler working smoothly and efficiently. We’ll also make sure your unit is properly winterized to avoid damage when the temperatures drop.
Want to make maintenance even easier? Join our Home Maintenance Care Club. Members receive regular service reminders, discounts on repairs, and priority scheduling — so you’re never left sweating in a heatwave.
