Know Your AC Warning Signs

As a homeowner in Lewisville, Highland Village, Flower Mound, Lantana or the surrounding areas, you are no doubt aware of the need for a dependable air conditioning system when it comes to the uncompromising temperatures of a Texas summer. Because our summer season can be intense, you need to know that your AC is going to be there for you when you need it most. If your system is compromised, it is mostly likely to break down while working its hardest.  Even seemingly minor problems can lead to very real damages if not addressed in a timely manner. Review these common AC WARNING SIGNS, and contact Southern Comfort Mechanical at the first sign of trouble with your AC system – you don’t want to be the one waiting for service during the busiest season of the year.

Reduced Cooling Output

AC WARNING SIGNS:  Your air conditioner previously cooled your home evenly but now is blowing warm air, only cooling sporadically, or only cooling certain areas effectively.  This decrease in cooling output should be taken very seriously. You may have a refrigerant leak, an air flow issue, or problems with mechanized components such as fans. Whatever the issue may be, it is best to have it resolved as soon as possible, both for the sake of your comfort and for the condition of your system.


Premature Shut-Down

AC WARNING SIGNS:  Your AC seems to be starting up fine, but running only briefly before shutting back down.  This system issue is known as short-cycling. Short cycling may occur for a few different reasons, such as very dirty air filter restricting airflow and overloading the motor, or a faulty thermostat registering temperatures incorrectly, causing the system to cycle off before your house is actually cool enough. Short cycling can also occur when the system experiences a refrigerant leak or a failing run capacitor that cannot maintain the appropriate electrical charge in the motor. Short-cycling puts a lot of unnecessary stress on your system that could result in increased damages or premature breakdown. Call our office as soon as you notice your system cycling in this manner.

Strange Sounds

AC WARNING SIGNS:  Popping, whining, grinding, whistling, clanging, hissing and other atypical sounds. One of the most obvious signs of a system in need of repair are odd sounds coming from any component of your system, and should prompt you to call Southern Comfort Mechanical to schedule a service appointment with our professional technicians right away. These sounds are warning signals from your unit, and continued use could potentially make the problem worse and far more expensive to repair.

Ice on the System

AC WARNING SIGNS:  Frost or ice on your system’s supply lines or coils.  It would be easy to mistake ice on the evaporator coils of your unit as a sign that your air conditioning system is working well. The reality, though, is that icing in an AC system could indicate refrigerant leaks, dirty coils or filters, restricted air flow or operational issues. Ice accumulation is a sign that your system is not able to absorb heat from its environment, which is your AC system’s primary role. If you notice ice on your coils or refrigerant lines, call Southern Comfort Mechanical right away for service.

Tripped Breakers
AC WARNING SIGNS:  An unresponsive system with a tripped or melted electrical breaker.  If you find your AC is tripping your circuit breaker frequently, do not ignore the issue. The breaker is a safeguard against power surges that can damage your electrical system and start electrical fires. There are a few reasons your AC unit could be tripping the breaker, including dirty coils, a shorted motor, an issue in the breaker box, or an issue in the compressor. Regardless of the cause for the tripped breaker, we strongly advise you to address the issue as soon as possible so no further damage is done to the system.


High Energy Costs

AC WARNING SIGNS:  Higher than average summer energy costs.  Any number of issues in your Lantana home can contribute to increased energy usage and electricity expenses. However, if you’re having a hard time identifying why your bill has increased, read over the other AC system distress signals above and see if any of them sound familiar. An air conditioner that is not routinely maintained, a system that is compromised in any way, or an improperly sized unit could all be contributors to system inefficiency.

Not properly maintaining your system or seeking repairs in a timely manner can compromise both your budget and your comfort in your home. Let the Southern Comfort Mechanical team diagnose and repair any problems with your AC as soon as you discover them. Call us today at (972) 420-1700.

Extra, Extra! The Cost of R-22 Expected to Double in Price in 2015!

If your air conditioning system is still using the old R-22 refrigerant and you’ve been band aiding it for the last few summers, you may want to consider replacement for many reasons. Repair, efficiency, government regulations and the price of rising refrigerant are all major factors. Southern Comfort Mechanical, serving Lantana and surrounding areas, is here to help you make the correct long-term decisions when it comes to your home and your air conditioning and heating needs.

Repairing your older HVAC systems can be a hassle for many reasons including: the part has become obsolete, specials order parts that may take days to arrive, constant repairs and expensive refrigerant leaks. (See chart below) As of now, R-22 is costing upwards of $75-90 a pound; that cost will be increasing even more as they are limiting production of it. In 2014 they produced and imported 51 million pounds and in 2015 they are only releasing 22 million pounds. And as of 2020, it will be non-existent. Southern Comfort Mechanical only uses clean, straight from the factory refrigerant. If you think you are getting a really good deal on it, chances are they are using recycled refrigerant. DO NOT use recycled refrigerant in your air conditioning system. That is just asking for your system to be compromised.

The Energy Independence and Security Act of 2007 has rolled out their new regulated standard efficiency. As of January 1, 2015 here in Texas it is required to have a minimum of a 14 SEER (seasonal energy efficiency rating) for both air conditioning and heat pumps. Be sure that when shopping for new equipment you keep this in mind. You may think you are getting a really good deal from other local Flower Mound companies, but if it’s not up to the SEER rating, you are getting robbed.

There are many factors to consider when you are looking to replace your HVAC system, including cost. With the cooler weather and winter right around the corner, now is a great time to take advantage of Trane’s special offers. Now through December 15, 2014, Trane is offering 0% interest for 60 months on qualifying systems or up to $1000 cash back. The cost of rising refrigerant and new government standard are now two major considerations. Southern Comfort Mechanical is here to answer all of your questions and guide you to making the right investment for the future of your home. Schedule your free estimate today by calling 972-420-1700.


R-22 Versus R-410

R-22 Versus R-410

R-410a, R-22, set, hike! No, they aren’t football plays; although they sound like it. They are two different types of refrigerant. “Freon” as some people call it is essential to making your system run and cooling your home. Although they do the same job, they are made of different properties and one has been deemed harmful to the environment.

R-22 is a type of refrigerant that has been around since the 1950s. Recently the Environment Protection Agency (EPA) has determined that R-22 is depleting the ozone layer. Due to that, the government has tightened their regulations and the cost of R-22 has skyrocketed and will continue to do so. What does that mean to you as the consumer?  It means higher prices, “hard to find” parts which are necessary to keep your old system running, and possibly going days without air conditioning.  Chances are if your unit if 11 years or older, your system is still running on the old R-22 Freon. Sure a pound or two here and there isn’t going to break the bank, but repairing a leak in the system and continually charging the system can cost a lot.

R-410a is now used to replace R-22.  It works the same, but it is not harmful to the environment should it leak into the atmosphere. It’s also much cheaper, half the cost and will continue to drop as R-22 rises. What you need to know is that you can’t put R-410A into an R-22 air conditioning system.  If your system runs on R-22 and you are continuing to charge it year after year, you need to think about replacing the system.

So whether you are considering replacing a part or your entire system remember, R-410a is the way to go. Not only will you save money on refrigerant, you will also save money with a more efficient system and lower utilities and help the environment.  Southern Comfort Mechanical is here to help you in your decision while being environmentally friendly. We only install R-410a complete systems, we use energy efficient parts, and we recycle everything. Little things do count and we are proud to do our part!

Gooooo Green!
