How much space can a 2-ton air conditioning unit cool?A building's energy efficiency, including air leaks, insulation and shading, and the climate it's located in impact how many tons of air conditioning are needed to cool it down. How do you troubleshoot problems with your air conditioner? The cooling capability of a central air conditioning units is measured in tonnage. A 1-ton unit can push out cool air at a rate of roughly 400 to 1,000 cubic feet per minute. Window air conditioners are generally labeled in British Thermal Units, or BTUs. A 12,000-BTU unit is the same as a 1-ton air conditioning unit. A 12 foot by 12 foot room will require an air conditioning unit with a cooling capacity of 5,000 British thermal units, or BTUs, according to the Energy St...

Central air units differ from window or portable models as they control the temperature of your entire home. Controlled by a single thermostat, you can raise, or lower the temperature, acclimating the climate to your desire. Summers can be rough in Chicago, so be sure your unit works efficiently and properly. Most central air conditioners are connected to a home's forced-air distribution system. Thus, the same motor, blower, and duct-work used for heating are used to distribute cool air from the air conditioning system. HVAC makes living easier in extreme climates. It's important to know the proper size of the air conditioner you need for your home. If you install an air conditioner that is too large, it will cycle on and off too often, which will reduce the efficiency of the unit. If it is too small, your air conditioner may not be able to meet the demands of a hot, humid day.

I want steadier room temperatures and humidity along with cleaner indoor air. What type of system do you recommend?—Cyndee O.Dear Cyndee: Your old central air conditioner probably has a seasonal energy efficiency ratio of 10 at best. By replacing it with the most efficient new model with a SEER of 26, your electric bills savings can be about $2,500 over just five years.

These new systems also provide the most steady room temperatures and excellent humidity control. Controlling indoor humidity level is as important for comfort as keeping the house cool enough. This also impacts the indoor air quality, particularly for people with allergies.Consider replacing your old central air conditioner with a heat pump model. It is basically the same as a central air conditioner except it has a reversing valve to also produce heat. During mild weather, it heats at a lower cost than running a furnace. During colder weather, the furnace takes over.Your three basic options are fully variable, two-level and single-level cooling output models. Since you are seeking high efficiency, steady room temperatures, humidity control, less noise, and cleaner indoor air, a variable-output model is your best choice. It also is the most expensive system, so do a payback analysis first.Variable cooling models use variable-speed rotary compressors which are often called inverter technology.

They continually vary the cooling output to the instantaneous cooling needs of your house. The cooling varies in 1 percent increments from about 35 percent to maximum output.In early morning when cooling needs are low, the compressor slows down to about one-third of its maximum output. It runs longer and more efficiently at this lower speed. These long efficient run cycles maintain room temperatures within just ½ degree of the thermostat setting.These systems use a matching variable-speed blower. At the lower compressor speed, the indoor blower and outdoor condenser fans also run slower making the entire system, indoors and outdoors, much quieter than single-level models.When you set the desired humidity level on the thermostat, the blower speed automatically varies to control humidity. It can continue to dehumidify even when the room air is already cool enough. This eliminates that cool, but muggy feeling which may occur with a single-level system.The next step down in comfort, efficiency (SEER in the 20 range) and initial cost is a two-level cooling system.

This type of system runs at the more efficient low-output level the majority of the time. On hot afternoons or when you want quick cooling, it switches to the high-output level.Single-level output models with a single-speed blower speed are the least expensive to install. Since they have only one cooling output level, you can expect a room temperature swing of about 3 degrees between run cycles.Dear Jim: I have bought two different brands of low-flow showerheads with a lathering shut-off to save water. Both of them continue to leak water when I close the small lathering lever. Am I installing them wrong?—Tom G.Dear Tom: You probably did not install them improperly. The lathering shut-off valve is used to stop the water flow while lathering without having to readjust the water temperature again when you are ready to rinse.A lathering valve is designed to leak a little water to keep the hot and cold water pressure balanced. Without it, if someone flushed a toilet, you could get a shot of straight hot water when you start to rinse.
