This Texas school has two conventional buildings, each with 20 air conditioning units along its back wall. That’s 40 units for just one tax-supported school! What does it cost to install and run 40 ac units in hot, humid Texas? Also, consider that this is a school for less than 300 students. Cost to cool your building It depicts the back side of one of two buildings that function as a traditional Texas school serving 236 students in Kindergarten through Grade 12. Like many traditional schools, this building has a line of 20 air conditioning units along its back wall. The companion building has another 20 units along its back wall. That’s 40 AC units at just one school! Consider what it costs to install 20 units. How much electrical do those 20 units require? How much just plain expense does it take to install and run 20 units? And these units are not inexpensive toys. They are not $100 window units. By the time the unit is installed, each costs a minimum of $3,000 to $4,000.

And bigger units cost two to four times that much. The next time you drive through town, please think about this. Look at the schools, look at the churches and just do a rough count of the AC units you see. Keep in mind that most schools and churches hide their units along the building’s back side. As I drive through the suburbs of Dallas, I’m constantly stunned by the number of AC units I see at schools. cost of car ac repairMany have one major AC unit for each classroom.ac unit doesn't start That costs serious money – not only to install but to hook up, to maintain, to replace and most of all to furnish with power.how to care for window ac unit It’s no wonder that we receive so much acclamation for our Monolithic Domes. Our domes use one fourth that amount of air conditioning.

Most conventional churches and schools in Texas use one ton of air conditioning for each 250 square feet. The rule of thumb for a Monolithic church or school is one ton of air conditioning for each 1,000 square feet. That’s 1/4 as much! It takes a lot of money to heat and cool buildings such as the one pictured here – especially to cool them in Texas where, in some years, we have more than 100 days of 100 plus degrees.All room air conditioners drip — or at least they should. But drips in the wrong place or the wrong volume of dripping water may be a sign of a problem with the air conditioner.Why Air Conditioners DripAs the name suggests, air conditioners do more than simply cool the air. They help condition the air and increase comfort by reducing humidity. The basic concept is similar to the condensation that collects on an iced drink. The air conditioner's cooling coil or evaporator absorbs moisture from the room. The airborne water vapor cools into liquid form and then collects on cold surfaces in the air conditioning unit.

How Much Air Conditioners DripThe volume of dripping condensation from an air conditioner varies widely depending on humidity levels and temperature, as well as several details regarding the size, efficiency and installation of the air conditioner.On a summer day in a hot, humid climate, each window air conditioner can drip up to two gallons of water per day. Keep in mind that this water can be collected for use in landscape irrigation. Central air conditioning systems can collect 20 gallons of water per day, and some homeowners collect and divert that water for irrigation. On the other hand, air conditioner condensation should not be collected for drinking water because of the risk of lead exposure and other contaminants.Where Air Conditioners DripThe condensed water should leak from the back of the air conditioner unit whenever the unit is running. The water drips from the cooling coil into channels that should be angled toward the back of the unit. Some of the water is used to cool heating coils in the machine, but most will drip out of the unit.

If an air conditioner is not dripping, it may not properly be doing its job of dehumidifying the room. If it is dripping from locations other than the back of the unit, you may have a problem.Troubleshooting Dripping Air ConditionersPerhaps the most common problem with air conditioner condensation is water dripping out the front of the unit, caused by installation errors. Such drips can ruin furniture or flooring, and may lead to mold concerns. The back of the air conditioner should be slightly lower than the front to encourage proper drainage.Water dripping from the sides or front of the air conditioner could also be caused by air leaks. If the air conditioner is not properly sealed in place, hot outside air could turn into dripping condensation when it hits the cool air conditioning surface s. You may need to caulk and insulate around the air conditioner to reduce such condensation. This will also boost efficiency and could reduce energy bills.If the water freezes into ice rather than dripping out, the air conditioner likely needs servicing.

Homeowners thinking about installing a split AC system, or ductless air conditioning system, in their homes should also be aware of all the costs associated with doing so. After all, it is necessary not only to purchase the AC unit itself, but to have it installed by a trained and qualified HVAC professional. Unlike a simple window unit, there are a few specific connections that must be made between the condenser and the evaporators to ensure the system runs properly. Furthermore, proper insulating must be done to maximize energy efficiency. When hiring an HVAC company or contractor for mini split AC installation, there are some specific factors that must be taken into account. The cost of the unit itself usually ranges between $1,100 and $1,400. Beyond that, however, there are of course labor costs associated with any mini split installation. Depending on the amount of time it takes to install the unit and the number of evaporators being installed with it, labor can cost anywhere from $600 to $700 and usually takes around 10 hours.

Finally, there is also the cost of the materials needed to properly install and insulate the unit, such as tubes and insulation. Homeowners should expect to spend around $40 to $50 on these materials altogether. Researching and gathering quotes from various HVAC companies is key. Furthermore, having the installation done at certain times of the year, such as the fall or winter, can yield lower costs, as HVAC companies tend to be less busy. Homeowners should also be on the lookout for special promotions and discounts, such as free installation or discounted labor. Homeowners who do not have ductwork in their homes and are considering a mini split air conditioning system should start by carefully weighing both the advantages and disadvantages of such a system. One of the largest advantages of installing a mini split AC system is the fact that there is no need to retrofit an existing home with the appropriate duct and ventilation work, which can cost thousands of dollars. Furthermore, since these ductless AC systems do not require much complex wiring or tubing, they tend to take less time to install, lowering the average cost to install a mini split AC system.

Another great aspect of a split air conditioner is the fact that they can be customized to the home. For example, one condenser may have as many as four evaporators connected to it, all of which can serve different rooms around the home. These evaporators can be independently controlled, which is great for keeping electric costs down. For example, if a homeowner wants to cool just one room in the home, all he or she has to do is shut off the evaporators to the rest of the home. Finally, unlike a window-mounted air conditioning unit, most mini splits are mounted on the ceiling and do not need to be exposed through a window to the home's exterior. This creates an increased sense of security for homeowners as break-ins through window units are sadly quite common. Of course, mini split AC systems do not come without their potential drawbacks. For starters, these units are not nearly as energy efficient as a forced-air system like central AC. In fact, according to Energy.gov, mini split AC units can cost 30% more to run than a central air conditioning unit.

Furthermore, not all homes are well suited for mini split air conditioning systems. It will take a qualified HVAC contractor to come out to a home, assess the space and determine whether or not such a system can be installed. Finally, some homeowners are also unhappy about the look and space requirements of the split AC system. As we already said, mini split systems are cheaper (to install) than most other air conditioning systems. While a split AC unit may not cool a room like a heat pump or traditional system, it does provide the necessary coolness we all need. Fortunately, when comparing the average installation costs, you’ll understand why some homeowners choose mini split AC systems. In addition, if you don’t have ductwork in place, you would have to install it. According to our duct installation cost estimator, that will add roughly $1,000 to your total installation cost. When choosing a mini split AC system, homeowners need to decide which unit is best for them.

In general, there are two common types of mini splits: Single zone units are less expensive, but are generally only used to cool one area of the home. These are ideal for smaller spaces such as studio apartments. However, multiple zone units are designed to cool several spaces within a home. These also tend to be more expensive, as the capacity for these systems must be higher and more powerful. Like other air conditioning systems, mini split AC systems move hot and cold air where you need it. In the summer, your mini split evaporator will remove the heat inside your house, transport it to you condenser and release it outside. In the winter, the system can reverse the process and bring cold air outside. Furthermore, mini splits are also great for moving cold or hot air from one room to the other. Therefore, if your basement is cold (which they tend to be) and you’re sleeping in your bedroom, the mini split can take that cold air from the basement and move it upstairs.

Like other AC systems, the capacity of mini splits is based on its BTU and SEER rating. Both help determine the strength of airflow. A single unit should be rated at 24,000 BTU with a SEER of at least 17. To determine what system you need, please check out AJ Madison’s BTU calculator. Design should be considered with any home remodeling project and mini splits are no different. Luckily, you can install your mini split AC system in a few different areas. Mini splits can be attached to your ceiling or wall. High up on the wall is more common, but as time has evolved, more homeowners are disguising them in the ceiling. If you choose to install your mini split ac unit in the ceiling, you can have it suspended, recessed or concealed. As you might imagine, recessed or concealed units are very popular for smaller units. The less noise in the room, the larger it will feel. The location of your mini split AC system must be considered before purchase. While a mini split installation is not easy for the common homeowner, it is possible.
