Understanding Filter Driers: Desiccant

A large proportion of air conditioning systems being manufactured today include the component known as a filter drier. This useful part is responsible for capturing water and other contaminants that would otherwise contribute to wear, corrosion, and other serious problems. Of course, not all filter driers are made in the exact same way. This article will discuss differences in one key aspect of a filter drier’s composition: the type of desiccant material used.

The Basics 

Desiccants are one of the most important aspects of a filter drier. Just as with the desiccant packets used to eliminate unwanted moisture in packaged food, the desiccant in a filter drier is there to suck up any moisture that manages to get into the refrigerant lines. This is important because that water would otherwise mix with the lubricants used inside of the system, forming highly corrosive acids as a result. Such acids greatly accelerate the processes of wear and corrosion.

Desiccant Materials 

There are two main types of desiccant used in filter driers: molecular sieve and activated alumina. The particulars of how these materials do their job is somewhat complex; all you really need to understand is that each type has its particular strengths. Activated alumina is prized for its ability to absorb much large quantities of water. This acts to extend the lifespan of the filter drier.

Molecular sieve on the other hand, is prized for its ability to capture not just water, but also any organic acids that have formed as the result of that water mixing with lubricants. In other words, molecular sieve is capable of protecting your system to a much higher degree. Which type of filter drier you choose has a lot to do with the needs of your particular air conditioning system.

3 Reasons to Schedule an Air Conditioning Service in the Spring

Before you know it, the hot and humid days of summer will be here, and it is important to know that your air conditioning system is going to keep you cool and comfortable. Many people just keep running their system year after year with little to no maintenance, but in the long run, that can be detrimental. Here are 3 good reasons why you should have your air conditioning system serviced every spring.

  1. Regular service will keep your air conditioner efficient. When things aren’t taken care of, you will find yourself lowering the thermostat to stay comfortable. The system will have to work harder to keep things cool and the humidity low, which will, in the long run, cost you money on your utility bills.
  2. A system that is taken care of will not break down unexpectedly. If you have it looked at before the season starts, chances are a worn-out part will be noticed and replaced before the hot weather starts. It’s no fun not having air conditioning during the dog days of summer when you have to wait for a part or a technician who is busy with other air conditioning issues.
  3. Your air conditioner will have a longer life span. We know replacing an entire air conditioning system takes a toll on the finances, so it is wise to do whatever you can to keep it in good working order. An annual tune-up will keep everything running well so you can rest assured your system will be there to serve you for many years.

Scheduling service on your air conditioner system is a comprehensive way to make sure it is ready for the summer ahead. A technician will clean the system including the coils, lube moving parts, replace the filter, drain the condensate line, check fluid levels, inspect ductwork, and inspect wiring. This regular service will ensure your system is dependable and efficient, and ready to keep you cool.

A Big Spike In Power Bills? It Could Be An Air Conditioning Problem!

The summer heat is brutal and our HVAC systems are running around the clock. We are not surprised when we get our higher electricity bills in the summer months. But, look closely. Is the bill unusually high? Is the cost increase more than it was last year? You could have an air conditioning problem.

A clogged up and dirty condenser coil results in overworked HVAC systems. The air is not freely flowing through the system. This could cause your system to continually cycle on and off using more electricity to maintain your comfort levels. A cleaning is a quick and inexpensive fix that will save your system and return your power bill to normal.

Thermostat problems are one of the most overlooked issues with our HVAC systems. If your thermostat is not correctly calibrated and working properly, it could cause your system to turn on and off too often. This is a common problem and (like with the coil issue), a cheap fix. Allow a professional to check, calibrate or if needed, replace your thermostat. This is a much less expensive option than a year of higher power bills.

A tiny leak in the refrigeration lines could be allowing small amounts of the refrigerant to leak out of the system. If the leak is small, you may not hear or feel the difference. But you can see the difference in the electric bills. Your HVAC system is struggling to keep the house at a cooler temperature with less than enough refrigerant to do so. Over time, the leak will get worse and eventually a costly repair is necessary. Fixing a minor leak allows minor problems to remain minor.

All of these little issues can cause you headaches and cost big money if neglected. All of them would be addressed in your bi-annual cleaning and system checkup.

Do not let your hard-earned money be stolen by unnecessary electric bill surges. Make sure that you call Cunningham Associates today for an air conditioning system inspection in Atlanta, GA.

3 Things to Do Before Worrying About Your Air Conditioner

It’s summer time! That means fireworks, pool time, cold lemonade, watermelon, and barbecues. Summer can also mean hot days and staying inside just to stay cool. This can be fun for a little while, but staying inside can mean running your air conditioner all day. That can result in lots of questions. Is it normal for my air condition to always be running? Why won’t my air conditioner turn off? Why does it seem like my air conditioning isn’t getting cold enough? Don’t fret yet! These are all common questions. Below is a list of three easy steps to try first before letting the stress sink in.

 

1. Make sure you actually have a problem

 
With the air conditioner running constantly, it’s easy to assume something is wrong. However, remember that it is summer. If your home is reaching the air conditioner temp without problem and you energy bills are roughly what they were at this time last year, then you may be stressing over nothing. Expect that your air conditioner will be running more frequently because it is hot outside!

 

2. Make easy changes

 
One tiny issue with something as important as the air conditioner can cause people to go into a frenzy. But, before you completely freak out, there are some easy things to check. Make sure that your air filters are clean. At the very least, air filters should be changed every three months. But, when your air is being used constantly, changing it monthly may be necessary. Also, make sure your vents aren’t being blocked. Something as simple as moving drapes, curtains, or furniture can make a huge difference in the amount of airflow allowed in your home.

 

3. Talk to an expert

 
Few and far between have much knowledge of the internal workings of your air conditioner. So, if you’ve tried the easy options, it may be time to call someone who knows. When looking for a good technician, trust is important. Pick a company that has state of the art devices to get accurate information, but also gives you a home town feel.

 
Don’t let something as silly as your air conditioner ruin your summer. Contact Cunningham Associates today. They’ll be able to answer your air conditioning service questions or concerns.

5 Common Sense Explanations for Seeking a Commercial Air Conditioning Specialist

Commercial air conditioning problems aren’t situations that you should sort out on your own. Commercial grade HVAC units are complicated mechanical devices that require years of experience and training to properly diagnose and repair. It is never a good idea to attempt to fix your commercial property’s HVAC unit if you don’t know what you are doing.

Here are five reasons to hire a commercial air conditioning specialist to maintain and repair your HVAC system.

  1. Safety: The obvious first reason to trust a heating and cooling professional with your HVAC is for safety reasons. Repairing HVAC systems requires training and knowledge. Don’t risk your safety, call a professional for all repairs.
  2. Speed: If you own an apartment building, the last thing you want is for your tenants to worry about not having air conditioning. To expedite the repair process, always trust a professional with the repair job.
  3. Money: If you think it’s expensive to pay a professional for HVAC repairs, then imagine the cost of trying it yourself and failing. The cost to repair an ailing machine is far less than replacing an entire unit.
  4. Guarantee: Commercial HVAC companies offer service guarantees on their work. With a work warranty presented in writing by your trusted HVAC professional, you can rest easy knowing the job will always be done right.
  5. Maintenance: On-going HVAC maintenance, which is carried out long into the future, gives you peace of mind that all necessary maintenance and upkeep is priority number one.

While you may not need your air conditioning unit right now, you will need it in the near future. It is necessary to contact an HVAC professional to not only perform annual maintenance, but to also look for potential problems that may have developed during the winter while the unit sat dormant.

A seasonal tune-up performed by a qualified professional may include inspections and repairs to the following components:
 

  • Blower
  • Drain line
  • Coils
  • Operating pressures
  • Refrigerant levels

Air Conditioning Repair: How to Get the Most From Your AC

Having your air conditioning go out is a homeowner’s nightmare. Especially in the middle of the summer, you do not want to spend time in the sweltering heat in your own home. Also, when your air conditioning goes out, you are probably dreading the worst, that you will need to replace your entire system. But in many cases air conditioning repair could be all you need.

A good HVAC company isn’t just going to try to sell you a new unit. Oftentimes, your AC unit can be repaired by replacing a part. Another thing to consider if you dread your AC going out is having annual maintenance done on your unit to keep it running optimally for as long as possible. In the long run, annual maintenance can save you money.

However, if your AC breaks and it turns out it needs to be replaced, there is good news. Units today are much more efficient than they used to be. Even standard models are more efficient than older units, so you can start saving money on energy costs right away.

Enjoy a Stress-Free Experience with Professional Air Conditioning Installation

When you want to improve the cooling in your home or replace the current air conditioning system, you should consider contacting a professional right away to discuss the situation. Although you might think you are capable of handling something like this on your own, replacing or installing a brand new air conditioning system is not easy and is a task best left for qualified professionals.

When you get professional air conditioning installation, you also get a stress-free experience.

Determine the Right System

The first part of the process is determining what kind of cooling system you need. For instance, your home may be exceptionally insulated, which might prevent you from needing central air conditioning.

It all depends on numerous variables that professionals have the knowledge and experience to analyze, and make sure you end up with an air conditioning system that satisfies your needs.

Work with Your Budget

When you have a particular budget to work with, professionals know how much most projects cost, especially after taking a good look at your property and seeing what needs to be done. When you use professional installers, you can feel confident that your budget will not be exceeded.

A Convenient Installation

It is nice to know that when you invest in an installation by professionals, they will work around your schedule to make sure that you are comfortable throughout the entire process.

Guaranteed Professional Results

An amateur installation has no guarantees, and this is exactly what you want to avoid with something as substantial as a cooling system. To have a stress-free experience, professional installation is a necessity.

With all of the benefits above, hiring a professional should be an easy decision to make. Call us today to schedule your professional air conditioning installation!

What to Look for When It Comes to Air Conditioning Installation

Air conditioning is a staple in most homes today. When it’s time for air conditioning installation, you’ll want to do it right the first time since it’s such a time-consuming job. For this reason, there are a few things you need to consider before getting started:

You want an efficient unit so that it doesn’t cause a drag on your energy bill, thus costing you a lot of money. In order to understand this, you need to know what the SEER (Season Energy Efficiency Ratio) rating is.

It’s also important to install the right size unit. If it’s too small, it won’t cool your home adequately. However, if the unit is too big, it will continuously turn off and on in just a short amount of time. Not only will this use a lot of energy, it will place a lot of strain on each part of the unit.

Another important thing to do is what’s known as an energy audit. This looks at your insulation, air sealing, and whether there are any leaks in your ductwork. If any problems are found, you should take remedial actions at the time that you install your new central air conditioning system.

Now that you understand how vital it is to choose the right air-conditioning unit, you can see why it’s just as important to choose an experienced contractor, like Cunningham Associates. We can help you work through all the necessary considerations that you need for finding the best air-conditioning system for your home.

Why Your Air Conditioner Leaks

One of the most common air conditioning problems is leakage or pool buildup. Water is a natural byproduct of the air conditioning process. When warm humid air passes over the evaporator coil, the air is cooled and the humidity condenses on the cold surface of the coil. This condensate collects in a sloped drip pan and then leaves via a drain line. When this drainage is blocked or prevented in some way, you will have a leakage problem. The following are a few reasons why you might have a leakage problem:

Blocked Condensate Drain Line: A common reason for water leakage is a clogged drain line that is blocked by dirt, insects, or other debris. When the drain line can’t carry the water out of your house, the drip pan overflows!

Leaking Drip Pan or Condensate Drain Line: Cracks or holes in either the drip pan or condensate drain line will leak water into your home. A damaged drain line or a rusted drip pan may be responsible for this problem.

Condensate Pump Doesn’t Work: Some air conditioners use a pump to force the condensate out of your home. These are used when the water must flow uphill. When the pump doesn’t work, water builds up and leaks.

If your air conditioner is leaking, don’t ignore the problem because water-soaked walls and floors lead to mold damage which is expensive to repair. Contact us to get the problem resolved.
