If your space feels hot and humid, a fan won’t cut it. What you really need is an air conditioner that also works as a dehumidifier. These combo units cool the air and remove excess moisture, making your home feel more comfortable and your air easier to breathe. In this guide, we’ll show you the best air conditioner dehumidifier combos and explain how to choose the right one for your needs.
Why Choose an AC and Dehumidifier Combo?
Excess humidity doesn’t just make you sweat—it can lead to mold growth, musty odors, and damage to furniture or electronics.

These units are ideal for high-humidity climates or rooms like basements, sunrooms, or bedrooms that get warm and sticky.
Benefits:
- Two-in-one function: Cool the room and control humidity with one device
- Cost-effective: No need to buy separate appliances
- Better comfort: Dry air feels cooler and more breathable
- Mold prevention: Removes excess moisture to protect your home

How to Choose the Right AC Dehumidifier Combo
1. Consider Room Size
Pick a unit with enough BTUs for your space. Here’s a quick guide:

| 600–700+ | 12,000–14,000+ |
2. Check Dehumidification Capacity
Look for a pints-per-day rating. The higher the number, the more moisture it can remove—especially useful in basements or humid climates.
3. Portability vs Permanent Installation

4. Smart Features

5. Noise Level
If the unit will run overnight or in a shared space, choose a model rated below 55 decibels. Inverter compressors are typically quieter.
