Inverter vs Conventional Models

Wednesday, June 29th, 2011

When trying to pick out the right air conditioner for your home, you’ll probably stumble across mention of inverter technology. Air conditioners using inverter technology are quite similar to conventional air conditioners in many respects, but they have some distinct advantages under certain circumstances.

What’s the Difference?

A conventional air conditioner is set up to switch on when the indoor temperature reaches a particular level. When it comes on, it introduces cool air at a constant speed until the desired temperature is reached and then it shuts off completely. Your indoor environment remains more or less the same temperature, but you will be blasted periodically with a lot of cold air. While the air conditioner is off, the air in the room gradually warms up until the temperature gets high enough to trigger the air conditioning system to come on again.

An inverter, on the other hand, comes on powerfully at first to achieve the desired temperature, and then reduces its fan speed gradually to maintain that temperature without shutting off completely. This method of cooling maintains the desired temperature more consistently than a conventional system can. It also requires a lot of careful measurements, not only for how much cooling power is needed in your room, but for the speed at which the cool air will dissipate from that room.

Initial Installation

One big reason that more people didn’t opt for an inverter air conditioning system in the past was that the initial installation cost was often considerably higher than that of a conventional system. However, advances in the technology have made inverter air conditioners much more affordable in recent years. Digital programming, more accurate measurements and efficiency in every aspect of the field are responsible for the drop in price.

Savings over Time

While inverter air conditioning systems are still typically more expensive than their conventional counterparts when it comes to initial cost, they provide excellent savings over time that can more than make up for the difference in purchase price. This is particularly true in areas where air conditioners are not running at full blast constantly.

When they are both maxed out, a conventional air conditioner is more efficient than an inverter. But when the temperature is such that a conventional model would switch on and off all of the time, an inverter will easily outstrip it in terms of energy efficiency.

To ensure you get the right model for your home, carefully calculate the difference in installation costs, the amount of cooling your home needs and the current efficiency of your cooling system. If everything lines up perfectly, an inverter system may be right for you.

How Do I Find the Right Size Unit for My Room?

Friday, June 24th, 2011

When buying an air conditioner, there are a lot of things you need to take into account. One of the most important is the size and power of the unit you choose. Air conditioners come in many different sizes, so if you really want to get the most out of your purchase, you need to do your research and pick one that fits your home like a glove.

Square Feet and BTUs

The best way to determine how large of an air conditioner you need is to match the number of BTUs the unit has to the square footage of the room you want to use it in. That means you need to know what room you’re buying it for before you make your purchase.

The number of BTUs needed goes up proportionately with the room size, so even if you don’t have exact measurements or if your room is oddly shaped, you can get a good idea of how large an air conditioner you need. For instance, a 400 to 550 square foot room is best served by an air conditioner with between 8,000 and 11,000 BTUs, while a room that’s only 250 square feet would probably be fine with a 6,000 BTU unit.

Bigger Isn’t Always Better

One of the most common mistakes people make when buying an air conditioner is to assume that the bigger the unit the better it will work. The truth is that buying an air conditioner that’s too big for your room is just as much of a waste as buying one that’s too small.

A larger air conditioner will cost more, and it will probably make the room too cold. It will also cycle on and off more frequently than a properly sized unit and it won’t be able to properly control the humidity level, leaving you with a cold, damp environment. That’s not very comfortable.

Other Factors

The square footage is definitely the most important piece of data you’ll need before buying a new air conditioner for any room in your house. But don’t forget to take some other factors into account as well. For instance, if the room has particularly high ceilings or receives a lot of direct sunlight, you’ll probably need a slightly more powerful unit than the straight square footage would indicate.

If you’re not sure how certain features of your home will impact your buying decision, call a professional who can help you get a more exact idea of what it will take to stay cool.

What Features Should I Look for When Buying an Air Conditioner?

Wednesday, June 22nd, 2011

There are so many different types and styles of air conditioners on the market these days, it can be difficult to figure out what features are worth paying attention to when it comes time to buy one for yourself.

Of course, the most important thing to do is make sure you get an air conditioner that’s appropriately sized for the space you’re trying to cool. But what should you look for beyond that? Here are a few features you might like to have on the unit you purchase:

  • Energy Efficiency – The more energy efficient your air conditioner is, the less your cooling costs will be. It’s as simple as that. So when you’re evaluating devices, remember that it’s worth paying a little bit more up front for a more energy efficient unit. It will save you money in the long run and you’ll be doing your part to help the environment.
  • Dehumidification – Just about every air conditioner controls humidity to a certain extent in addition to cooling. But some do this better than others. There are also air conditioners with separate dehumidification settings for those days that are more humid than hot. Even when you need both cooling and dehumidification, it’s nice to have control of each of these independently.
  • Timer – Being able to program your air conditioner to switch on and off at different times of day is more than just convenient; it will save you money. You don’t want to leave your air conditioner running all day when you’re not home, but it sure is nice to come home to the comfort of an air conditioned space. If your air conditioner has a timer, you can have both. Just set the unit to come on a half hour or so before you get home and you’ll enjoy cool, refreshing indoor comfort right when you get home without paying through the nose to keep your home cool when no one is there.
  • Easy-to-Use Controls – As simple as this one seems, you might be surprised at how inconvenient the controls on some air conditioners can be. So when you’re evaluating your options, make sure you research how easy each unit is to operate. This can definitely save you from plenty of frustration in the long run.

Air conditioners come in many different shapes and sizes. To make sure your decision works best in your home, do your research well in advance. When the summer heat kicks in, you’ll be glad you did.
