Selecting the correct power level is vital, and our Sort by BTU tool simplifies the selection process significantly. Smaller rooms are perfectly served by our 6,000 BTU and 9,000 BTU high-efficiency units. For standard living areas, the 12,000 BTU and 18,000 BTU models remain our best-selling choices. Larger open-concept spaces may require the heavy-duty performance of a 24,000 BTU or 30,000 BTU system. As you scale up to light commercial needs, we offer 36,000 BTU and 42,000 BTU solutions. For whole-home coverage, our largest inventory includes 48,000 BTU, 55,000 BTU, and 60,000 BTU options. Matching the square footage to the right capacity ensures your Heat Pump Systems operate at peak efficiency. Please consult our Technical Data for electrical requirements before purchasing higher BTU condensers.
