So I asked a long-winded version of this question in another thread, but haven't really received any good responses yet. I'm going to condense and try again... There is an 8" duct feeding a 6x12 register in my kitchen, that I need to relocate. By doing nothing else, will changing the size of the register to say a 10x10 or 12x12 provide more air and/or better distribution at all? I am pretty sure I need more "washing" of the exterior windows/doors in the area, so I am relocating the register to the center of the room (and will get a 4-way type as well), but I also wondered if going any bigger would help any too. And if so, what would be the biggest size? Just speaking in generalities here and it doesn't have to be exact... hvac air-conditioning ducts register Given a circular 8" duct you are dealing with an airflow area of about 50 sq/in. You currently have 72 sq/in opening. I haven't seen a picture of your register - some are not as open as others so it is hard for me to know for sure but... with 72 sq/in opening the air would just dribble out.

This is fine for a floor vent that is unobstructed by walls and furniture but usually not what you are going for. You are usually looking to push the air out a few feet out into the room. A smaller register does this. Also somewhat closing a register does this - however this could push air at unadvantageous angles and you don't want air hitting walls and furniture. Most registers I size are about the same sq/in's as the duct or a little less. I am looking for the air to be pushed out hard so that it creates airflow in the room. Big rooms with oversized registers can have hot spots away from the register. Now the downside of going to small with your register is that it is too loud. Unless you are severely undersizing your register, the noise is really the only issue. So a bigger register will not help cool or heat your room better. Putting the register in a better location and making sure the air is shooting out in an efficient manner and at an efficient angle is key.Browse other questions tagged hvac air-conditioning ducts register or ask your own question.

This guide will walk you through everything you need to about air conditioning costs including the air conditioner itself, installation costs and air conditioning system maintenance costs. When you're researching the cost of an air conditioner, there are three important factors that will determine the price: Prices can vary a lot by brand, as much as $2000 between the cheapest and most expensive air conditioners. We compared 2.5-ton models (more on that later) and the cheapest air conditioner we found was the Payne at $1400. The most expensive air conditioner in our research was the Lennox at $3410. The question is how important are the brand names? Most experts would say that a mid-range air conditioner like the Gibson at $2265 is more than sufficient for most people. Beyond that, the more expensive air conditioners like the Lennox or the American Standard at $3195 offer nice-to-have, but unnecessary features like quieter running speeds and more accurate climate control.

The more expensive brands tend to also have better efficiency, but we'll talk more about that later.

Yellow Lab Puppies For Sale WvCooling is described in either tons or BTUs. A ton, believe it or not, refers to the amount of ice melted in a day. So a 1.5 ton air conditioning system is the equivalent of melting 1.5 tons of ice for a day. BTUs (or British Thermal Unit) is a measure for cooling that's more common to use nowadays.

If you ever get confused, just remember that 1 ton of cooling is equivalent to 12000 BTU/hour of cooling. Window air conditioners are usually less one ton; a smaller air conditioner is roughly 2 tons and largest are up to 5 tons. The best size for you depends on the square footage of the space you're trying to keep cool, the insulation of your home and even the number of occupants. Of course, you can opt to get a lower or higher BTU depending on your preference. Here are the rough prices for different air conditioner sizes, including installation: The last factor that you need to consider for your air conditioner is efficiency. Air conditioning efficiency is measured in SEER or the Seasonal Energy Efficiency Ratio. SEER measures how much energy (from your home's electricity) is converted into cool air. More expensive brands tend to have higher SEER ratings, so while you might spend more upfront, you could end up saving money in 5 years from your energy bill. Here's the cost of different air conditioners by SEER rating:

How much can your SEER rating affect your energy bill? It depends a lot on your local electricity costs (dollars per kW/h) and how often you'll use it. If you're using your A/C unit on a daily basis and all throughout the year, then you'll likely want a SEER rating above 20. But if you're only using your air condition system for a couple months, then we'd suggest getting 15-18 SEER. This is the general breakdown for choosing a SEER rating: Note: once your air conditioner is installed, a great way to keep your bill down is to lighten the load. Keeping blinds down, shading windows, shutting off appliances and improving insulation can help reduce the amount of air conditioning you need. When doing home renovations, you can also use more high-efficiency products. For example, if you're replacing your roof, a cool roof can save half a ton of cooling over the year. The best step is to get several HVAC contractors to provide you with quotes for your installation, but the range should be between $500 & $1000, assuming you don't need any major ductwork done.
