The Preventative Maintenance That Will Save You the Most

Wednesday, March 30th, 2011

Having a high performance, energy efficient HVAC system will save you a good deal of money in terms of your monthly heating and cooling bills. But that efficiency will not last unless you also take the necessary steps to keep your equipment in good working order. While regular maintenance visits from a professional HVAC technician are an important part of this, there are also several things you can do on your own to keep your equipment running at peak efficiency.

  1. Keep it Clear: The first thing you should do is to make sure that there is plenty of space cleared around your outdoor unit. Whether it is the condenser and compressor for your air conditioning system or part of your heat pump, that outdoor equipment needs to have plenty of space to vent hot air. Also, the space will mean that debris is less likely to develop inside the unit.
  2. Clean the Condensing Coil: While your technician will do this when they make their annual visit, it is best to clean your coil more than just once a year. Just make sure that the power is turned off to your unit before you begin. This will help the unit cool air more efficiently and can prevent a whole host of other problems from developing.
  3. Check on the Blower: If your blower is not working right or the blade is clogged, your HVAC unit will not work properly. Make sure your blower fan is free of all debris and that is turns freely once you have cleaned it. If you are still having a problem with it, you may have to call a technician for repairs. Cleaning the blower out on a regular basis, however, should keep this from becoming a problem you need a professional for.
  4. Air Filters: You should also make sure you change your air filters regularly. This can help to keep your indoor air clean and healthy and it will also enable your HVAC system to run more efficiently.
  5. Clean it Out:Clean out any debris that you can reach from any part of your system. Just make sure any time you work inside your HVAC system that you have all of the power turned off. Anything from leaves to dust can get in there and cause a problem if it is allowed to build up over time. As long as you are on top of things and keep to a regular schedule of maintenance, none of this should take you very long.

The Energy Efficiency Rating of Central Air Conditioners: What Is it and Why Is it Important?

Monday, March 28th, 2011

When you are shopping for a central air conditioning system, you will have to evaluate your options based on a number of different factors. For instance, you will need to decide which type of system is the best match for your home and for your particular cooling needs. It is also important to make sure that the central air conditioner you choose is the right size for the cooling load it will have to take on.

However, it is also very important to evaluate your central air conditioning options based on how energy efficient they are. This will have a great deal to do with how much you pay in terms of cooling costs each month, which makes it easy to see why you should take it into account before you make a purchase.

The energy efficiency of a central air conditioner is generally expressed as a seasonal energy efficiency rating, or SEER. The SEER numbers you will typically find on the latest air conditioning systems range from eight to 19.5 with the higher numbers signifying a more energy efficient model.

So it is pretty easy to figure out that a central air conditioner with a higher SEER will save you some money monthly because it will use less energy to get the same job done. But central air conditioners with high SEERs also typically have high price tags. So to determine how high of a SEER you need, you will need to know more exactly how much more money you will save as you move up in the rankings.

You can do this by comparing the SEER of the system you currently use with the new system you are considering and compare how much your current energy usage would cost you with each model. Basically, you want to pick a central air conditioner that will save you enough to offset the purchase price of the unit.

Often, this means that you will be best off with a SEER 14 or SEER 16 because these units save you a considerable amount over older models without carrying too high a purchase price. However, the amount you save will be directly related to how much you use your central air conditioning system, so if you live someplace that is extremely hot for a large chunk of the year, it may be worth it for you to buy a very high efficiency air conditioning system.

Warning Signs: When to Call for an Air Conditioning Service

Friday, March 25th, 2011

The last thing you want is to be without an air conditioner during the hottest days of the year. Ideally you would never have to call for service to repair your air conditioning system, but just like anything else, your air conditioner will break down once in a while. However, you can dramatically reduce the inconvenience and cost of emergency air conditioning repairs if you are able to spot the warning signs of a problem before it shuts down your system completely.

For instance, all air conditioners make noise, but if your air conditioning system is suddenly making much more noise than it used to, chances are that something in there is not working properly. Calling for repairs when you notice this sudden increase in noise from your system will greatly increase the chances that the repair will be relatively minor and that you will not have to go without air conditioning when you need it most.

Also, it is a good idea to call for service if your air conditioning system does not seem to be doing as good a job as it used to when it comes to cooling your home evenly and effectively. Uneven cooling is a good sign that something is not working right within your system. And even if your air conditioner continues to work, it will probably be using up more energy than necessary for a less than ideal end result.

Along these same lines, a noticeable increase in humidity in all or part of your home is another good indication that something is wrong with your air conditioning system. Air conditioners both cool and dehumidify the air, so if yours stops removing humidity properly, you need to find out why.

In fact, even if you do not notice any difference in the way that your air conditioner is performing, you can still spot a problem if you keep a close eye on your energy bill. If you see a sudden increase in the amount of your bill because of the amount of energy that your air conditioning system is using, it is a good sign that something is not working right.

It may be tempting to put off calling for repairs, particularly if your air conditioner is still able to keep your house comfortable. However, it will likely be much cheaper and more convenient to have the repairs done early rather than waiting until the unit breaks down entirely.

Tips for Upgrading Your Central Air Conditioner

Wednesday, March 23rd, 2011

When the time comes to upgrade your central air conditioner, you will have a lot of things to take into account. If you were generally satisfied with the performance of your old system, it can be very tempting to stick with a similar model. But if you do not examine all of the options out there right now, you may very well be missing out on a great deal.

If you already have a central air conditioner in place, chances are that you also have ductwork throughout your house. In that case, you will probably be better off with a packaged air conditioner as opposed to a split system. If it is a split system you are replacing, however, you should probably keep your search limited to other split systems. Installing a packaged air conditioner when you do not already have ducts in place can dramatically increase the overall cost of the project.

You will also want to make sure that the system you choose is compatible with the heating system and air handler that you already have in place. Most central air conditioning systems can be integrated easily with all types of heating systems, but you should still check to make sure this will not be a problem, particularly if you have an older heating system.

In terms of picking out the right new system for your home, energy efficiency is probably the main factor to consider. While just about every air conditioner on the market right now will be much more efficient than the unit you are replacing, you want to make sure you get a model that will provide you with the optimal savings in the long run.

This does not necessarily mean that you should go out and buy the most energy efficient air conditioner out there. In fact, because the more energy efficient units are also typically more expensive, you may not actually save money by going that route. But you will do well to choose a unit that will save you enough monthly to offset the installation costs and for most people, that means that you will want an air conditioner that is either a SEER 14 or SEER 16.

Of course, the actual amount of money you will save as you move up through the SEER rankings depends on how much you use your air conditioner to begin with. If you live somewhere with very hot weather and you use your unit for a large chunk of the year, it may very well be worth it for you to opt for a very high efficiency model.
