Atlanta Heating and AC Guide: Reasons for End of Summer AC Tune-Up

Monday, September 24th, 2012

When the summer winds down and you find yourself turning on your Atlanta air conditioner less and less, the first instinct for most people is to start preparing for winter. But there are very real benefits to performing in-depth maintenance on your air conditioning system now, before the winter comes and the system is left to sit in the cold for many months.

 Why the End of Summer is a Good Time for Maintenance

The end of summer is a good time to have your air conditioner serviced because it has just finished running for weeks or possibly months at a time. That means that quite a bit of wear and tear has developed and the system will be forced to sit like that all winter. Possible issues can become even more substantial in the winter months if the system is not prepared for that time.

What You Should Have Done

An end of summer tune up for an air conditioner is less intensive than a spring tune up, but should be done nonetheless to avoid problems in the winter. Such a tune up includes cleaning and changing filters, cleaning the coils of any possible dirt build up, clearing the space around your condenser unit and cleaning its fins and coils, and programming your thermostat to ensure it is working properly. An Atlanta air conditioning technician will also remove the drain pan and clear out the condensate line to avoid freezing in the winter and run a final diagnostic on the machine to ensure it is in good working order.

If you’re only going to have one maintenance tune up performed on your air conditioner, the spring maintenance visit is the most important, but to avoid unwanted repair needs in the spring and to prepare your system for the long winter ahead, consider an end of summer tune up as well.

Why it is Important to Winterize Your Atlanta Air Conditioner

Monday, September 10th, 2012

A quality air conditioning system has become a necessity for many Atlanta homeowners, especially for those who live in warm climate. It is the only way to maintain a comfortable indoor temperature in the heat of summer. Like any other equipment, though, Atlanta air conditioning systems also require regular maintenance so they can continue to function effectively. Winterizing your air conditioner is one of the important maintenance tasks that helps to enhance the lifespan and performance of your system.  Here are some of the reasons why it is so important to winterize your air conditioner.

  • To Protect Your Air Conditioner

An air conditioner is an expensive piece of equipment, so you need to protect it to get maximum payback on your investment. Air conditioning systems bear a heavy burden during hot summer months. So, simply turning off the system in winter months is not enough to ensure it will be ready for the next summer. Winterizing it helps you protect your system, no matter how harsh the winter weather gets so you don’t have to worry about whether it will work when the heat comes back again.

  • To Save a Lot of Money in Air Conditioner Repair

As you keep your air conditioner switched off after summer passes, there are more chances for leaves, dirt, dust and debris to get in and clog up the moveable parts inside the system. Winterizing your air conditioner is the best way to clear away this type of dust and debris. Any trained professional can do this work effectively and quickly, without creating a mess in your home. Cleaning dirt and debris from air conditioner helps you save tons of money in expensive repairs in future.

If you have window mounted air conditioners that cool the air by pumping water over a series of cooling pads, winterizing the unit is especially important. It gives you a chance to check whether there is any water left in the air conditioner. Draining water from the unit can help prevent it from freezing and causing damage to costly parts.

  • To Enhance the Performance of Your Air Conditioner

Most of the home owners seal off air conditioning vents and ducts, once the hot summer months are over. These areas are the main sources of heat and draft waste within the home. Winterizing your air conditioning system provides you with an opportunity to remove all the sealants prior to using the air conditioner in summer months.

Winterizing your Atlanta air conditioner is important to add to the life of your system and to save yourself expenses. To schedule a maintennace appointment or get your heating system ready for winter, give Cool Air Mechanical a call!

Atlanta Air Conditioning Guide: Indoor Air Conditioning Components

Monday, May 21st, 2012

Air conditioning in Atlanta is a modern convenience that we can easily take for granted as long as all the parts are working well.  In every unit, no matter the size, the basic process is one of extracting heat from the conditioned space and moving it to the outside, leaving cool air in its place.

This process easily divides into indoor and outdoor components.

Air Conditioning 101

Based on the principal of thermal energy which states that heat gravitates toward cooler temperatures, compounds known as refrigerants are moved through a closed loop system, repeatedly contracting and expanding between liquid and gas forms, alternately releasing and absorbing heat along the way.  The particular chemicals are selected for their abilities to transform from one state to the other at low temperatures.

While the refrigerant evaporates into a gaseous state within the looped system, it absorbs heat, removing the stale air from the space being conditioned and evacuating it to the outdoors. The warm air is pulled through ducts to meet with the cooling loop.


The cooled air is distributed through ducts or tubing and released into individual spaces.  Additional ductwork is required to remove the stale air and pull it back to be reconditioned as it passes over the loop containing the refrigerant.  The air is moved in both directions by a blower, usually electric and sized to handle the amount of air no matter the building.

Ductwork is also sized to handle appropriate volumes of air. To maintain efficiency, large trunks distribute along central lines to smaller ones reaching farther out. The return air is usually taken from common areas.

The grates are found in the walls, floors and often as part of the dropped ceiling. When combined with a forced air heating system, the total energy use is much more efficient.

Looped Coils

The refrigerant is enclosed in a loop where it can expand and contract to make its transformation from gas to liquid and back again.  To change into a heat-absorbing gas, it travels through the evaporating coils, an intricate series of delicate fins that meets with the ductwork to regenerate the conditioned air.

An exchange valve allows just the right amount of liquid refrigerant into the evaporator coils.  If there is too much, the tube is flooded too tightly to allow expansion of the molecules and room to attract the heat.  If too little, the process is inefficient.

Cool Maintenance

When set up and maintained on a regular basis, your Atlanta air conditioning system should function with little attention and over sight. To schedule a maintenance visit today, give Cool Air Mechanical a call!

Things You Should Never Do To Your Atlanta Air Conditioner

Monday, May 7th, 2012

Your Atlanta air conditioning system provides such comfort on blistering days, it seems it was a gift.  If it is broken, however, it can be very frustrating.

With proper care and maintenance, a central air conditioner should last for a decade or two.  Sometimes, however, people can do simple things which, in retrospect, should have obviously been avoided.

Some examples:

  • Don’t block the air intake–air is vital to the process, so laying anything over the unit (a towel or clothes to dry) will significantly strain the motor.  Always make sure there is enough clearance.
  • Don’t block the vents–likewise in a home, it is easy to move a sofa or lay an area rug over a grate in the floor or cover an unsightly vent in the wall with a pretty painting.
  • Don’t just set a unit in the window and trust the sash to hold it in place–make sure it is fastened properly according to the directions;
  • Don’t think it will run forever without cleaning the fins, vents and changing the filter at least once a heating season;
  • Don’t leave the units exposed in winter–always cover when not in use for long periods of time;
  • Don’t bury the condensate drain in the ground–in central units it is vital that the drain is left with a clear flow away from the house;
  • Don’t install the central unit on the ground–there are pre-made pads or mix up a little concrete and have the satisfaction of pouring a nice little pad yourself (and you can write your name in it too).
  • Don’t steam clean or use hot water to clean the fins–damage and corrosion can easily be caused by the heat; flush with warm water or spray.
  • Don’t overload the system with refrigerant– a task performed by a Atlanta AC professional, but a problem you should be aware of.
  • Don’t remove the overload relay to force continuous running–VERY dangerous and a guarantee of damage.

Air conditioners–especially the ones fitting in windows–are pretty much “plug and go” appliances, but a little attention goes a long way to ensure years of comfort. For more information on how to keep your AC in peak condition, give Cool Air Mechanical a call!
