“My bedroom is above our garage with a large south facing window. This means it gets super hot no matter the central AC setting.

Frequently Asked Questions
Q: What’s the difference between BTU and tonnage in air conditioners?
A: BTU (British Thermal Unit) measures cooling output—higher BTUs mean more cooling power. Tonnage is another way to express capacity; 1 ton equals 12,000 BTUs. For home use, BTU is the standard metric you’ll see on product labels.
Q: Can I use a portable air conditioner in any room?
A: Yes, as long as you have access to a window or vent for the exhaust hose. Portable units are ideal for renters or rooms where window installation isn’t possible. Just ensure the room size matches the unit’s BTU rating.
Q: Are evaporative coolers effective in humid climates?
A: Not really. Evaporative coolers work best in dry, arid climates because they add moisture to the air. In humid areas, they may make the room feel stickier instead of cooler.
Q: How often should I clean my air conditioner filter?
A: Most manufacturers recommend cleaning the filter every 2–4 weeks during peak usage. A dirty filter reduces efficiency, increases energy costs, and can lead to poor air quality.
Q: Do window AC units need professional installation?
A: Not usually. Most window units are designed for DIY installation with basic tools. Just make sure your window frame is sturdy and the unit is properly secured to prevent accidents.
