Air Conditioning Tip: How Insulation Improves Efficiency

Wednesday, August 28th, 2013

We all want our air conditioning systems to be as efficient as possible. The better and more effectively it can cool the air in our homes, the less we have to pay in our monthly bills. That means a great deal in Lutz, FL and other nearby towns, which have to battle the Florida heat and humidity every year. You can keep your unit efficient by scheduling regular maintenance from a qualified professional, as well as ensuring that the components of your air conditioning system are properly insulated.

There is usually insulation on the unit’s coolant line, which carries evaporated refrigerant to the compressor coils to start the cooling cycle. Ideally, you want to keep the refrigerant as cool as possible before in enter the compressor. Otherwise, the compressor must work harder to pressurize the gas and cool it off in the condenser coils: increasing wear and tear on the unit as well as forcing it to expend more energy.

Insulation should also be installed on the ductwork of a central air conditioning system. It’s less necessary in parts of the house which receive conditioned air, but many times the ductwork is laid in the attic or similarly non-conditioned places. Furthermore, any ductwork exposed to a heat source or even a sunny window may warm the cooled air passing through it. That means it will take longer to cool down your house and subsequently increase your energy bills.

In some cases, insulation may never have been installed on these components or the insulation may have deteriorated over time, a fairly common occurrence in Florida’s muggy weather. Either way, it pays to contact a qualified HVAC professional to address the issue. It will save you money on your monthly bills and help keep your air conditioning functioning the way you need it to.

3 Hard to Detect Air Conditioning Repairs

Tuesday, August 20th, 2013

An air conditioning unit is an absolute necessity in Tampa, with its hot summers full of muggy days. When the unit breaks down, air conditioning repairs need to take place swiftly and professionally, in order to minimize the impact on your comfort levels. But not every problem can be detected easily, and not every issue announces itself clearly. Here are three hard-to-detect conditions that could signal a need for air conditioning repairs.

  • Refrigerant leaks: When leaks develop in the refrigerant lines, it impacts the overall effectiveness of the unit. Ice forms on the evaporator coils, interfering with the cooling process and forcing your air conditioner to work harder to adequately cool your house. The leaks themselves can be hard to spot, though professional service techs know how to do so accurately.
  • Dirty components: Dirt and dust can build up if you don’t maintain a reasonable maintenance schedule. This can create problems with the unit’s various components, particularly the evaporator coils which can form ice on the surface and disrupt the cooling process along the way.
  • Condensate problems: The condensate drain is connected to a condensate pan, which catches condensation from other parts of the system and removes it. In some cases, a pump is used to facilitate that process. If the pump is malfunctioning, if the drain line is clogged or if the pan is improperly installed, the condensation won’t drain properly. The water will stagnate and eventually overflow, creating other issues in the system. The leak maybe be small and go unnoticed without a careful examination.

You may be able to spot these problems in general ways: if your monthly energy bills go up, for example, or you notice that the air blowing into your home isn’t as cool as it once was. By and large, however, they require a professional service techs to detect and repair. Ierna’s Heating & Cooling can address hard-to-detect air conditioning issues in Tampa and throughout the greater Tampa Bay area.

Does Dirt and Debris Impact My Air Conditioning System?

Monday, August 12th, 2013

Land O’ Lakes, FL has to deal with high summer temperatures and humidity, just like the rest of the Tampa Bay area. A good air conditioning makes it possible for your house to stay comfortable even when the mercury creeps up. Like everything else, however, wear and tear can impact the effectiveness of your air conditioning system, and dirt and debris can lower its efficiency, necessitating serious repairs somewhere along the line.

Dirt and debris have the most prominent impact when they  cover the evaporator and condenser coils. The coils play an important role in cooling air. When the coils get too dirty, they are unable to transfer heat, which makes it harder to cool air the air in your household. The condenser coils need to transfer heat from the refrigerant to the outside air, and the evaporator coils need to absorb the heat from the air in your home.

Dirt and debris can also enter the duct system or other key parts of you air conditioning system.  That decreases the air quality in your home, increasing the risk of allergens or irritants. In addition, the air filters designed to prevent dirt and debris from getting into your system may become clogged: reducing air flow and creating more strain on the system.

You can avoid these problems fairly easily first by replacing the air filter on a regular basis, and then by scheduling a annual maintenance service from a trained professional. An expert can not only spot potential problems before they get out of hand, but clean the dirt off of key components to keep them running. A separate duct-cleaning appointment will clear the dust and dirt out of your ducts, while sealing any leaks that might have caused the dust to seep in in the first place. The trained professionals at Ierna’s Heating & Cooling can perform air conditioning maintenance services throughout the Land O’ Lakes area. Call us today to set up an appointment.

Air Conditioning Repair Tip: Signs your Ductless AC Needs Repair

Tuesday, August 6th, 2013

During the hot summer months, problems with the performance of your air conditioning system can seriously disrupt your comfort. That is why you should always contact a skilled professional to schedule any necessary air conditioning repair in Wesley Chapel at the first sign of trouble. The sooner you have your air conditioning system repaired, the less likely serious issues with your AC are to develop.

Here are a few tips to help you recognize the need for ductless mini split air conditioning repair:

One of the great benefits of ductless mini split systems is that they are able to cool your home very efficiently. There is no ductwork used, as individual, wall mounted blowers handle the distribution of cooled air directly. If you notice that your ductless mini split air conditioning system costs more and more to operate, there may be a problem with the system requiring professional air conditioning repair. It is possible that there is a refrigerant leak in your system, that a fan is not operating properly, or that some electrical component is malfunctioning. Whatever the cause of your efficiency loss, it is always best to have the situation evaluated and resolved as soon as possible.

Another sign that your ductless mini splits may be in trouble is the development of unfamiliar sounds and odors during their operation. While these issues may not seem terribly serious, they are often indicative of more serious problems with the system developing. Remember, even the most serious problems with your air conditioning system are unlikely to spring up overnight. It is much more likely that they are the result of operating a compromised system, giving the problem the opportunity necessary to become more severe. That is why routine ductless mini split maintenance is such a good idea.
