How to put a single, superior air conditioning unit to work cooling your whole home
High Btu Air Conditioners
Central Air Not Cooling
If you're shopping for air conditioners, you may have noticed air conditioning units in the 20,000 Btu, 24,000 Btu, or 25,000 Btu range, all the way up to 27,000 Btu and 34,000 Btu, and wondered if you could use that to cool 3 bedrooms, 2 bedrooms and a kitchen, or even your whole house.
Although central air might be cooler, it's some times more expensive.
Preparing your home system
To cool your whole house with a single air conditioner, use your furnace fan. Put the unit in a room with a return duct, or setup the air conditioner as close as potential to a return vent. Try to place the unit where the impact from noise will be minimized. Normally furnace fans are settled in basements or out-of-the-way parts of homes, but find the best location for your system.
Close the furnish vent in the room where you setup the air conditioner, and leave the return vent open. Close all the other return vents in the system.
Tips for maximum efficiency
- Close furnish vents in all the rooms except those you are occupying.
- Running the fan at the top speeds can boost efficiency, but will be noisier.
- Don't use an exhaust fan to 'push' hot air out. This will pull hot air through cracks and leak cool air.
Final Thoughts
Using a high Btu Air Conditioner to pump cool air through your existing ventilation law can save you 0 - ,500 upfront, save 0s on monthly electricity bills, and keep you cool in the summer months.
Finding the right air conditioner
First, you're going to need to reckon the Btu requirements for your home. An Ac Size Calculator can help you to find out how many Btu you need to cool inescapable room types and square footage or square feet of the room.
You may have heard that going the next size up is a good thing, but there is a drawback. Going more than 1.5 or 2.0 times the actual Btu requirement will cause your unit to cycle on and off, whereas allowable sizing keeps air dehumidified, and saves money on energy bills by running more efficiently.
Think: slow-and-steady = efficiency.
