Central Air Installation Prices Window air conditioners are certainly better than no air conditioners at all on a hot summer day, but quieter, more efficient central air conditioning represents a major step up in household comfort. Often referred to as just central air, a whole-house central air conditioning system distributes cooled air through a home or office space via a duct system. Central air can be added to your existing forced-air heating system, although an existing HVAC network isn’t required. In this buying guide you’ll learn more about centralized air conditioning and the cost. Central Air Conditioning Considerations Below are some of the points you should keep in mind when shopping for a new central air conditioner. There are three main types of central air conditioning systems: a split system, a mini-split system, and a package system.

In a split system, the compressor (which cools the air) is located outdoors and the air handler unit (responsible for distributing the cooled air throughout the house) is placed indoors. Compare this to a package system, in which the compressor and air handler are placed together, usually on the ground or roof. A final option, and one that is relatively new, is the mini-split system, also known as a ductless mini split system. This type of system is technically not the same as central air, although installing several can serve the same function. It is ideally suited for older homes without ductwork and cooling additions of up to 1,200 square foot. Once you’ve decided on the type of central air conditioning system, it’s crucial to select a setup that is powerful enough to cool your entire home on hot days, but not so powerful that it doesn’t adequately remove humidity. The size of an air conditioner is expressed in tonnage or BTUs (British Thermal Units) per hour. A cooling contractor can help you evaluate the size of the system you need by performing what’s known as a Manual J load calculation.

Although sizing for central air conditionings systems is determined formulaically, there is more leeway when choosing system efficiency. The seasonal energy efficiency rating (SEER) of an air conditioner expresses how much cooling unit provides relative to the amount of energy it uses. The higher a unit’s SEER rating, the more efficient—and less costly—it is to run. The federal SEER minimum is 13, while 16 to 23 SEER is considered high efficiency. Central Air Average Costsair conditioning unit too large The actual cost of central air installation depends on a number of factors, including the size of the home as well as the unit’s tonnage and SEER rating.6 ton ac unit prices In a 2,000 square foot home with existing ductwork, central air conditioning costs $3,000 to $5,000 installed. rate residential hvac units

If ductwork is additionally required, costs could reach $6,000 to $10,000 or more. Mini-split central air conditioner prices average $1,500 to $3,000 installed. Note that while a high efficiency unit could cost up to 30 to 40 percent more than one with the minimum 13 SEER rating, the extra costs should be recouped in energy savings over the lifetime of the system.

Here we will discuss how by knowing what type of SEER unit to buy, will help make your decision on a new air conditioning unit much easier and could possibly save you money in the long run. What does SEER stand for? The word SEER is an acronym for Season Energy Efficiency Ratio. What is a SEER rating? The SEER rating of an air conditioning unit is the cooling output during a typical cooling season divided by the total electric energy input during the same period.

SEER is simply a formula that is described by the outcome of the following: Divide the system’s rated BTU’s (what ton the unit is, ex: 5 ton), by it’s stated SEER rating to determine how many watts it consumes per hour. Why is knowing this information important? This is one of the most frequently asked questions by a customer when they are deciding on what type of SEER air conditioning unit they should buy. There are numerous reasons why the customer should know what kind of SEER unit they need to buy. One of the main reasons a customer needs to concern themselves with is the operating cost annually of the unit. Everyone is always looking to save money and as a homeowner, you should know that the main source of your electric bill is your air conditioning unit; so why wouldn’t you want to save the most money possible right? Here in the next section, I’ll teach you the annual cost of different types of SEER units, so you can determine which unit best fits your budget.

In this section, I will teach you how to find the annual cost of a hypothetical air conditioning unit. The information we need to get started will be the size and SEER of the current air conditioning unit. For this example, we will use a 5 ton, 15 seer unit. First, 1 Ton is the equivalent to 12,000 BTU’s (British Thermal Unit). So what we will do is take12,000 BTU’s and multiply that by 5 (that’s what Ton our unit is) and we will get 60,000 BTU’stotal. Now that we have the total number of BTU’s for our 5 ton unit, we will take 60,000 and divide that by 15 (that’s the SEER rating of our unit), you can find the information on what ton and SEER rating your air conditioning system is, by going outside and looking at the nameplate on your air conditioning unit. Digressing back to our formula, we will take 60,000 BTU’s and divide that by 15to get 4,000. The value 4,000 represents the number of Watts our air conditioning unit uses per hour of operation. Second, we need to convert our Watts into KWH (Kilo Watts per Hour).

The reason we need to do this is so that we can determine how many KWH our air conditioner uses per hour. By taking a look at your energy bill, you will see you are billed by KWH and not Watts. Going back to our equation, we will take 4,000 and divide that by 1,000 (1 Kilowatt = 1,000 Watts) and we will get 4. The number 4 represents the number of KWH our AC unit uses per hour of operation., the average Houstonian uses 1,262 kwh a month and15,144 kwh yearly. Click Here for charts and graphs of this data. For the sake of arguments and keeping things simple, let’s just say the average person in Houston uses their AC unit 8 hours a day. 8 hours multiplied by 30 (I just used an average of 30 days in a single month) and we get 240 hours used in a single month. Next, we will take the 240 hours we just received and multiply that by 12 (the number of months in a year) and we get 2,880. This new number (2,880) represents the number of operation hours our hypothetical AC unit uses annually.

Finally, we will take 2,880 and multiply that by 4 (remember this number? It was the number of KWH our air conditioning unit uses per hour of operation) and we will get 11,520 kwh. This new number (11,520) represents the number of KWH our air conditioning system uses annually. Lastly, now that we have the number of kwh our AC unit uses annually (11,520), we will take that number and multiply it by the dollar amount our energy companies charge us per kwh. For the sake of keeping things simple once again, we will just say our energy company charges us 10 cents per kwh. So, we will take 11,520  and multiply that by 10 cents and we will get 1,152 or in other words,$1,152.00 annually for the cost of operation for a 5 ton 15 SEER unit. Now remember, this is all hypothetical. I just wanted to give you a foundation and a platform to work with. Now you can take all this information here and input your own data and see how this applies to you. Below are some charts displaying how different SEER units can save you money and energy.
