Miami Air Quality Guide: What Air Filtration Options are Right for You?

Monday, September 24th, 2012

There are a number of air filtration options currently on the market in Miami that provide substantial protection against high levels of pollutants, allergens and contaminants in your home’s air supply. From dust and pet dander to mold spores and bacteria, a good air filtration system can remove almost anything. Here are some options and how to ensure you get the right one for your home.

  • Standard MERV Rated Filters – MERV ratings are used to measure the efficiency of a filter at removing smaller particles from the air. Your air handler came with a stock MERV rated filter that could remove between 40% and 60% of the particles in your air – enough for most homes without high pollutant levels or those who suffer from asthma or allergies. There are higher MERV rated filters that capture many more allergens, however.
  • HEPA Filtration – HEPA filtration is the equivalent of an MERV rating of up to 20, meaning it can remove 99.9% of all contaminants 0.3 microns or larger, a perfect fit for homes with pets and plants and those who suffer from allergies to both or asthma.
  • Electronic Air Cleaners – Electronic air cleaners remove smaller particles from smoke or exhaust fumes and are highly efficient at ionizing and separating air from other gasses.
  • Comprehensive Air Purifiers – Air purifiers combine both mechanical filtration and electronic air cleaning to remove smaller particles from your air. They are also very efficient in other ways, often managing humidity levels and sometimes containing UV germicidal lights.

Depending on the scope of the air quality problem in your Miami home, there are quite a few possible solutions you can turn to. The key is to ensure that the solution you choose will be sufficient for the health of your family members. Call Air on Demand today to learn more about improving the air quality in your Miami home!

Richmond Heights Air Conditioning Repair Tip: Condensate Drain Line

Monday, September 17th, 2012

Your Richmond Heights air conditioner has a condensate drain line that removes the excess condensate produced by the system during operation. The moisture and other components extracted from the air are flushed through this line to ensure smooth operation. If a clog occurs in the condensate drain line, your air conditioner can stop working properly or freeze up entirely.

 Why Does the Condensate Drain Line Clog?

A clog usually occurs because of the sludge that builds up in the drain line. Because so much of the drain line is horizontal, this is only natural. But with time, that sludge can start to back up in a single part of the line and eventually create a full clog. If the clog is severe enough, the condensate water from the air conditioner can back up from the line, into the drain pan and eventually into the furnace.

 Fixing a Clogged Condensate Line

Your condensate line is a very simple component it shouldn’t take too long for a professional to take care of the problem.

First, your tech will start by turning off your air conditioner and then removing the panel on the indoor component of the system – where the evaporator coil is located. Inside is two pipes connecting your condensate drain line (usually a PVC pipe) to the evaporator coil. They will then look to see if your drain pan is backed up at all – and empty it if is full of water.

Next, they will look for the end of the condensate line where it leaves the house and connects to the outside unit. If your pipe ends in the ground or any debris and brush have built up around them, they will clean them away and dig out the area around the pipe to ensure it has clearance when draining. They will then flush the line with water to clear the clog.

Miami AC Tip: Why a Clean AC Helps With Indoor Air Quality

Monday, September 10th, 2012

Indoor air quality may be much worse than outdoor air quality these days. Removing pollutants and undesired objects from your Miami home to create a healthy and dust free environment is the best way to ensure good indoor air quality. One of the main sources for these types of contaminants is often your Miami AC system itself. Because your air conditioning system circulates all of the air in your home, any contaminants present inside it will be spread around with that air.

To prevent this from becoming a problem, you only need to keep up with some regular air conditioning maintenance and cleaning. Changing out air filters promptly according to manufacturer’s recommendations is important, as is having your air ducts cleaned out professionally on a regular basis. And your air conditioning system will work much better and stay clean longer when you have it professionally serviced once a year.

Because all of the air in your home passes through your air conditioning system, it is a natural place for air cleaning to take place. Depending on the severity of your indoor air quality problem, you may want to have some type of indoor air cleaner or purifier installed in your home. This is most commonly done inside the ducts of your air conditioning system, and can be a very effective way of improving indoor air quality.

But just because you have an indoor air quality system in place doesn’t mean you can neglect the proper care of your air conditioning system. If you don’t keep up with regular cleaning and servicing of your air conditioning system, the level of indoor air contaminants can overwhelm your air cleaner and make it less effective. So to ensure that you have the highest possible quality of air inside your home, it’s essential that you keep your Miami AC system clean and well cared for over the long term.

Miami AC Guide: Why Short Cycling on an AC Unit Can Decrease Efficiency

Tuesday, September 4th, 2012

Your Miami air conditioner’s compressor is more efficient the longer it is on. In fact, anything less than 5 minutes shows a sharp and sudden decrease in efficiency, largely due to how long it takes for the compressor to start cooling the air. It takes time to compress refrigerant and start removing moisture and heat. It takes at least five minutes for condensate to start running down the coil to the drain. If it cannot do this it simply evaporates back into the air supply and the efficiency and comfort level go down.

Generally speaking, an air conditioner is set to run on cycles that are as long as possible. So, if the heat load on a hot day for your air conditioner is only 50%, your system will turn on for 50% of the hour, turning on for 10 minutes, then off for 10 minutes, then on for 10 minutes at so on. However, if your air conditioner is sized to reach a higher percentage – closer to 75% on a particularly hot day – the system will remain on much longer.

On the flip side, if your system is not working properly or if it is too large, it can short cycle, meaning it produces a lot of cold air and then turns off after 5 minutes. That, in turn, means it can’t reach the efficiency levels it should. While part of this has to do with proper design of your HVAC system, another part is related to the operation of that system. Two-stage compression can help with this as well by running the system at a lower level if it is not too hot outside but you still need air conditioning.

If you notice your Miami air conditioner running on short cycles, it is important that you call Air On Demand to inspect it. While it could be a design issue, it could also be related to a bad thermostat, a refrigerant leak or even a problem with your compressor. In some cases, a simple fix and an upgrade to your thermostat can eliminate the issue. In others, replacement may be needed.
