Buying Guide: How to Choose Air Conditioners That Heat And Cool
What room size and BTU matter
Match BTU to room size to achieve efficient cooling and heating. Larger rooms need higher BTUs, but oversizing wastes energy and reduces humidity control. For multipurpose rooms, consider units offering both cooling and heating for consistent comfort year‑round.
What type suits your space
Window units save space and are easy to install, while portable units offer flexibility for renters. If you want the quietest operation, look for inverter or open‑window designs with noise‑reducing features. Windowless evaporative coolers suit dry climates but won’t replace a refrigerant AC in humid environments.
Energy efficiency and operating costs
Inverter technology can cut energy use by a substantial margin. Look for Energy Star certification when available and consider units with eco or sleep modes for long-term savings. Remember heat functionality uses energy; ensure the outdoor temperature range supports efficient heating in your climate.
Smart features and ease of control
Smart control, voice assistant compatibility, and remote operation simplify daily use. Check whether the app supports your phone ecosystem (iOS/Android) and whether voice assistants are supported in your region. A digital display and remote control help quick adjustments when you’re not using the app.
Installation, maintenance, and longevity
Ensure your chosen model has accessible filters for cleaning, and verify the unit’s venting requirements or window kit compatibility. Long‑term maintenance includes cleaning or replacing filters and confirming that heat operation remains efficient in seasonal temperatures.
Safety and suitability considerations
Heat function performance can be limited by very cold outdoor temperatures. If you live in an area with freezing conditions, plan a unit whose heating is effective in those temperatures or rely on separate heating systems for colder periods.
FAQ
- Do these units require professional installation? Most window and portable units are designed for easy setup and do not require professionals, though window installations may need basic tools and venting kits.
- Can I run cooling and heating at the same time? No. Most models provide either cooling or heating in a cycle, but some offer a dedicated fan or dehumidifier mode to support comfort year‑round.
- What’s the typical noise level? Inverter and quiet‑design models can operate around 32–45 dBA for cooling in low modes, with higher noise during peak cooling or heating cycles.
- Is Energy Star certification important? Energy Star indicates higher efficiency relative to standards, which can lower operating costs over time.
- Which unit is best for a bedroom? Look for smaller BTU units with quiet operation, heat capability, and sleep mode for minimal disruption.
- Do these units work in cold weather? Heat functions are typically designed to operate above certain outdoor temperatures (often around 41°F). Very cold climates may require alternative heating methods.
