Wow!! What can we say about air conditioning system filters? Today’s market is so saturated with air quality concerns and suggestions that it leaves most consumers with their head spinning. Global Cooling hopes to ease the pain just a little with some simple, basic rules and a little education.

Dirty Air Conditioning Filters: The #1 Cause of AC Failure

First and foremost, your filter should exist simply to keep your air conditioning system free of any harmful particles that clog the air flow, preventing a smooth movement of air throughout the duct work. This is the equivalent of not allowing the AC system to breath. Just like us humans, breathing is vital for your air conditioner, too. Dirty filters are the #1 cause of the AC failures that Global Cooling finds in a season. Over 90% of all service calls find filters that are just not up to the standards of the equipment’s requirements. Once again, just like humans, upon failure to breathe well your air conditioner begins to experience changes in its operation that compound over time, eventually leading to its failure. The compressor inside the outdoor unit is the heart of the air conditioning system; and like a human heart, when it is asked to work much harder than it was intended to, its life is shortened and failure occurs.

Indoor Blower Motors Have Limits

One more example of an overworked component is the indoor blower motor. When a shortage of air flow exists, the indoor blower motor’s design parameters are exceeded causing it to fail prematurely.

What Air Conditioning Filters Does Global Cooling Recommend?

Now that we know how important it is to replace your air conditioning filter on a regular basis, the next question becomes, which filter should you buy? Good question. Let’s start with explaining some of the different types of basic AC filters:

  • • 1-Inch pleated AC filters
    • HEPA (High Efficiency Particulate Arrestance) AC filters
    • Electronic AC filters
    • 4-Inch pleated AC filters
    • Reusable/Washable AC filters
    • Electrostatic AC filters

With so many basic AC filter options, it is easy to see why consumers are baffled by the choices and often choose the wrong filter for their specific application. Let’s keep it simple since we are not writing a book about air conditioning, air flow and filters. Keep in mind most home’s air conditioning ducts differ a great deal and must be examined by a professional for all viable options.

Still Not Sure What AC Filter is Right for your Home? Call Global Cooling.

Rule of thumb #1 is an older home’s air conditioning ducts were never designed to allow the movement of air required by new equipment versus 20+ year-old equipment. Keep in mind filters are rated for different levels of particle capture and air flow. Higher rate = lower air flow. Motor speeds have increased so greatly that a new system in an older home without the accompanying ductwork changes will require the filter with the most allowable air. Filters with a high capture rate will probably not be the best option for an older home. Somewhat newer homes may have larger ductwork so a high capture rate could be OK. To complicate matters, filters are now being used for more than just equipment protection and are being relied upon to remove allergens, smoke, odors and other medical reasons. For these special applications, a professional should be called to check the system’s vitals to see if it will still breathe well while performing these special tasks. Enough is enough! Clean filters keep your air conditioning system breathing, so change them often to help prevent costly repairs. Even better, call Global Cooling and we will do it for you and check out the system on a regular basis so you don’t have to.

Myths About Freon and the Ozone

While it is true that many types of freon are harmful to the environment, there are also many that are not. Do not fall prey to the myth that all air conditioning systems must be replaced if your air conditioner has R-22 or other environmentally harmful freon.

Don’t Replace that AC Unit Just Yet! Talk to Global Cooling First.

Air conditioners, heat pumps and ductless air conditioners in today’s market have many moving parts that can be replaced without involving interaction with the freon. While it is true that an old air conditioning system should probably be replaced due to its age simply because of its current efficiency, the cost of future repairs and other possible factors, some customers are just not able to wrangle the finances for such a costly endeavor.

An Involved Customer is the Best Customer.

Global Cooling believes that an involved, educated customer can make a decision that best reflects their personal air conditioning budget. That’s why we offer education, air conditioning repair options, air conditioning replacement options and some financing options as well. Our goal at Global Cooling is to make every willing customer a part of their air conditioning experience.

Air Quality Global Cooling

Air Quality with Global Cooling

We now know that Air Quality is a Huge factor for human health. A clean home can be a healthy home. There are several ways to keep air clean in a home that will not break the bank through filtering. The least costly is the filter. There are many types of filters made today and it can be confusing to determine the exact one to use. Every home has a different use pattern and therefore may need a different type or quality. The pleated filter is the most commonly sold today, but they are made for different air capture rates. In other words, some allow more or less air to pass through in an attempt to catch fine particles where others are made to only protect the HVAC equipment. One must determine their needs and choose accordingly. Many older homes were never designed to use any type of high capture filter and using them only hurts the system because of the lack of air flow. A system starving for air is an energy wasting machine. Also, the quantity of fine particles that a pleated filter traps tends to clog the filter very quickly, again starving the system for air. Most pleated filters can become clogged in a matter of days depending on their capture rate. We consumers are trained to replace a filter based on time and not filter failure. We recommend dating a filter, checking its condition in at least 30 days to determine its condition then making a determination as to how often it should be replaced. If air quality is not a factor for you, then an old style see through filter may be sufficient to only protect the equipment. Our staff is capable of determining the amount air that is required to operate your system safely and efficiently and give options for proper air flow and air quality. For the extreme cases of allergies or illnesses, there are Hepa, heavy duty air capture, electronic filters available. See photos for the different types of filters.

Global Cooling Tips

Green is the new energy standard for America and the world. Not just because we want to, but because of the increasingly rising cost of energy and fuels has left us grasping for alternatives to lower our energy bills. There are many ways to save on energy through Air Conditioning.

  1. Replace your filter often. A system starving for air is an energy wasting machine.
    Filters have changed in the last several years and if a pleated filter is used now in your home, it must be dated when installed, checked every 30 days to start and then make a determination of whether or not it needs to be replaced by examining its condition and then replacing it based on your specific use patterns. There is no standard because every home use is different requiring different replacement dates. There are many quality ranges of filter too. Some are very basic which may be sufficient to protect your AC equipment while others are designed to filter the air for breathing. These differences require different attention. Some homes that are older were never designed to accept the new pleated filters and the lack or air flow which they cause due to their high quality. If you are unable to implement these procedures, Global Cooling offers a maintenance program which provides all the knowledge required to ensure a clean and efficient system.
  2. Have the ductwork checked for leaks. Unfortunately, many older homes and even some new homes have had ducts come loose or were never sealed properly from the beginning. This allows the energy for cooling to be lost in the attic instead of being transferred to the home interior, creating a waste of energy. Older ductwork is also very thin and has a low R Value (thermal resistance. Simply put, the rate at which heat or cold passes through a particular item) because there was no alternative at that time. Today, thicker ductwork is available with increased R Value and can be replaced to save wasted energy.
  3. Replacement of an Air Conditioning system is the most effective way to see dramatically lower energy bills, but it comes with the highest outlay of financial resources. Sometimes keeping an older system running at tip top shape may be more cost effective than replacement, especially If you are not going to be living in the home for a long time. However, if the older system is experiencing constant failures, or an expensive failure, then replacement still may make sense for the long haul even if you are moving out of the home soon because one can factor the sale of a home with a new HVAC system as a selling advantage over other homes with older systems. We have several brands to choose from.
  4. Thermostats are a very good way to control the temperature and the amount of time that a system is on or off. Today there are a variety of programmable, digital and WI-FI thermostats that can be set or changed even if you are not at the home, allowing for accurate settings at the touch of a button. This method of control will save on energy if used correctly. We are knowledgeable in the installation and set -up of high efficiency thermostats. See our section on Nest thermostats.
  5. Rebates and credits are also available by some Electric companies when you make efficient changes to your home which include AC, appliances, windows, insulation etc. We highly recommend calling your local Electric Company for more information.
  6. Other viable options for saving energy are sealing windows, new windows, window coverings, doors, attic insulation, fireplace flues, the temperature setting of the thermostat, lighting fixtures or bulbs
