Common Air Conditioning Repairs: Why is My System Leaking Refrigerant?

Wednesday, June 26th, 2013

When you live in as hot a climate as Tampa, FL, any problem with your air conditioning system is a serious problem. At the first sign of trouble with your air conditioning system, contact the Tampa, FL air conditioning repair professionals at Ierna’s Heating and Cooling.  Our team has the tools, training and technical ability to ensure that any issues with the operation of your air conditioning system are resolved quickly and effectively to minimize any disruption to your comfort. One common problem that we encounter is a refrigerant leak. Here are a few potential causes of a refrigerant leak in your AC system.

There are a lot of joints and connection points in an air conditioning system. As your system operates, even when it is properly installed and secured, it is going to vibrate a bit. During years of operation it is possible for these vibrations to cause the connections in your system to loosen up a bit. If the connections through which your refrigerant flows become loose enough, it is possible for refrigerant leaks to develop. By allowing a professional AC technician to thoroughly inspect and tune-up your system, you can help to avoid such problems.

It is also very possible for the copper tubing that generally houses the refrigerant to suffer some corrosion over time. When this happens, it is possible for refrigerant leaks to develop along the tubing. This is more problematic than loose fittings, as it is an active leak that will require repair work or the replacement of the tubing altogether. Only a skilled professional should be allowed to complete such services.

Remember too that there are some instances where your refrigerant may be low without the development of a leak. It may have been improperly charged to begin with, or some refrigerant may have been lost during your last repair or maintenance service. Either way, it is important to have the right refrigerant charge in your system.

Refrigerant leaks can seriously hinder the operation of your AC. Call the Tampa, FL air conditioning repair professionals at Ierna’s Heating and Cooling to ensure that you have the right amount of refrigerant in your air conditioner. If there is a problem, our team can resolve it.

Air Conditioning FAQ: Why Do New Systems Have 410A Refrigerant?

Wednesday, June 19th, 2013

Air conditioning systems use a compressed refrigerant in order to absorb heat out of your home and then exhaust it outside. We wanted to put together a quick explanation about what refrigerants are and short history of them. Read below to learn more about one of the most important parts of your air conditioning system.

Air Conditioning Refrigerants: A Quick History

Years ago, refrigerants were highly toxic and often flammable gases like ammonia and propane. In 1928, a nontoxic, nonflammable refrigerant known as Freon was developed and gained widespread use. The term Freon was just the trademark of a variety of different blends of different types of refrigerants. The blend that became most prominent in home and commercial air conditioning systems was referred to as R-22. However, it was discovered that this kind of refrigerant damaged the earth’s ozone layer, and  it was phased out of new production in 2010. In its place is a new kind of environmentally friendly refrigerant known as R-410A. In Europe and Japan carbon dioxide is actually being used as a refrigerant as well.

Older Air Conditioning Systems

If you have an air conditioning system that was built years ago that still uses Freon, you will still be able to get it refilled with Freon. However, by 2020, Freon will no longer be available and if you have a refrigerant leak you may have to replace your whole AC system. However, there are huge benefits to replacing your air conditioning system. Not only will you get more efficient cooling, but you could increase the comfort of your home and reduce the need for air conditioning repair. Also, as R-22 is phased out, it will also become more expensive to repair these older systems since the R-22 will be scarce.

The air conditioning experts at Ierna’s Heating and Cooling can help you make sure that your AC is working well. Check out a few of the things that you can do to affordably increase your AC efficiency.

  • Regular maintenance – Probably the best thing that you can do to increase your AC’s efficiency is to get it regularly maintained. Over time, your air conditioning system will develop small problems and issues that cause it to have to work harder to cool your home. This could be things like an old fan belt, dirt in the pump motor, small leaks in the compressor, a clogged air filter and other types of issues. By getting maintenance for your air conditioning in Land O Lakes, FL you could be able to remove those problems and return some of the efficiency to your home’s AC system.
  • Change your air filter – One thing that causes many repairs for air conditioning units is a clogged air filter. Your AC’s air filter is there to keep dust, dirt and other debris from getting into the system. If it gets clogged it will restrict the flow of air into your AC unit causing it to have to work harder to pull that air in. Make sure that you change your air conditioning’s air filter on a regular basis—especially during the summer when you use it a lot.

Helpful Tips from AC Pros: How to Choose a System

Friday, June 7th, 2013

Are you satisfied with your current AC? Are you looking for an air conditioning system for your new home? Selecting the right AC for your home can feel a bit daunting. After all, considering the size of the purchase and the duration of time you’ll have to live with that investment, it’s no wonder that choosing a new system may give you pause. In today’s post, we’d like to give you some helpful tips from the AC pros on how to choose the right system for your home. 

  • Lutz Air Conditioning ServiceSizing: We can’t overstate this enough. The size of your air conditioner must match the size of your living space. During the installation process, a technician will perform a load calculation in order to assess how large a system you need to cool your home. If your AC is too large, then this results in inefficient cooling and short cycling. If it’s too small, then this results in inadequate cooling and potential system damage to overworking. Your AC needs to be just right.
  • SEER: This acronym stands for Seasonal Energy Efficiency Ratio and it’s given to every AC sold in the US. It’s a number that estimates the ratio between electrical energy input and cooling output over the course of a single season. The higher the number, the higher the energy efficiency. It’s a useful metric for determining long-term energy savings.
  • Ductless mini splits: Long used in commercial applications and throughout the rest of the world, ductless mini split air conditioning systems are beginning to gain popularity in the States. They are highly prized for their SEER ratings, which can reach as high as 27. They can also be installed in places where central air conditioning can not because they don’t require ductwork.

If you’re interested in a new air conditioning system, make sure you find the right installer for the job. Call Ierna’s Heating & Cooling today for comprehensive, quality air conditioning installation services.

By checking and replacing your air filter about once a month during the cooling season, you can avoid many performance issues related to impeded airflow.
  • Enroll in regular maintenance: There’s no substitute for professional maintenance. The knowledge and technical expertise of a qualified HVAC technician gives him or her the skills need to make sure your system functions effectively. By inspecting, cleaning, and adjusting your AC on a regular basis, you can be sure that your AC receives the care it needs to perform well for years to come. It may even be required by your manufacturer’s warranty.
  • Upgrade: If your AC is old and worn out, or constantly needs repair, you should consider upgrading to a new system. Today’s air conditioners have vastly improved their ability to cool homes and to do efficiently. Speak to your local professional if you are concerned about the condition of your AC.
