And here we are, arriving at number one on our list of best-selling HVAC equipment—the Aquastrong 1/38 HP Condensate Pump. This little powerhouse is everything you need to keep your HVAC systems running smoothly without a hitch. Let’s dive into what makes this the top choice.
High performance? Absolutely. This condensate pump is equipped with an efficient, thermally protected motor that offers quick draining while maintaining an impressively quiet operation. It moves water at a rate of up to 85 gallons per hour and can lift it as high as 20 feet vertically. Yeah, 20 feet! That’s enough power to handle the condensate from your AC units, furnaces, and dehumidifiers without breaking a sweat.
But what really sets this apart is its hi-level safety switch. This isn’t just about draining water—it’s about protecting your equipment. The pump’s sensor detects rising water levels, and when it hits the danger zone, the safety switch kicks in, automatically shutting off your HVAC system. No more tank overflows, no more water damage—just peace of mind.
Compact? Absolutely. But don’t let the size fool you. Its vertical centrifugal pump design comes with a removable 1/2 gallon reservoir, making it easy to clean, operate, and maintain.

With five 1-inch inlet ports, it connects effortlessly to multiple systems at once, giving you versatility without the complexity.
It doesn’t just perform—it thinks. The pump automatically starts when the water reaches 2.28 inches, and it’ll shut off once it drops to 1.26 inches. That’s precise. With a 3.3-foot UL power cord and 3-prong plug, safety and convenience are baked in, giving you more flexibility in where and how you install it.
And maintenance? Worry-free. Just clean the reservoir, float, and filter every six months to keep things running smoothly. Plus, Aquastrong backs it all up with customer support that’s got your back, whether you’re using it for your furnace, AC, dehumidifier, or even a commercial ice maker.
