Air Conditioning Repair: Why Your System Blows Cold Air

Monday, October 28th, 2013

Most problems with air conditioners come down to one thing: a lack of cold air in your home. The more you understand about how air conditioning works, the easier it will be for you to identify and issues that crop up. Specifically, here is a simple explanation of how your AC cools the air in your home.

The process entails a circulating system of refrigerant gas. The gas begins by entering a compressor, which subjects it to a great deal of pressure and therefore increases the temperature. From there, it moves into a set of condenser coils, where the heat is dissapated into the outside air and the refrigerant condenses to a liquid. The high pressure liquid refrigerant then flows to the expansion valve.

The valve acts like the spray tip of an aerosol can, releasing a set amount of the liquefied refrigerant into the expansion coils. Inside those coils, the liquid evaporates and turns back into a gas. In the process, it absorbs heat from the air around the coils, cooling it. That cold air is then blown into your home with another fan: distributed through a series of ducts and lowering the temperature throughout your household.

Assuming this process is functioning correctly, it can’t do much wrong: as long as your system blows cold air properly, it’s doing its job. One exception occurs when the air conditioning unit is too large for its space, in which case it cools the air too quickly and cycles on and off too rapidly, costing you energy and causing unnecessary wear and tear on the system. In any case, if you experience a loss in cool air, or your system isn’t blowing the air sufficiently, it’s time to call in a repair service. The professionals at Ierna’s Heating & Cooling can get to the bottom of the problem with courtesy and professionalism. Call us today to set up an appointment.

When is the Time Right for an Air Conditioning Installation in Tampa?

Monday, October 21st, 2013

Your air conditioning system should provide you with many years of reliable service, but eventually, you’ll have to replace it with a new one. When you are installing a new air conditioning system in Tampa, you probably don’t want to do it during the hottest days of the year. Installation in the middle of summer can be difficult because it leaves you without a proper air conditioner just when the temperatures are peaking. There’s also the question of whether or not your air conditioner is ready to be replaced, or whether a repair/upgrade might be more appropriate. When is the time right for an air conditioning installation in Tampa? The answer depends on the state of your existing unit.

With proper maintenance and care, an air conditioning unit can last for a long, long time. The question or replacement comes when costs rise high higher than you’re prepared to spend. That could mean excessive repairs, when the unit keeps breaking down and/or a given repair costs more than the existing unit is worth. It could also mean that the unit has become so inefficient that your monthly bills are rising higher than you’d care to spend.  When those costs reach a tipping point – especially if your unit is more than ten years old– then the time is probably right for a new air conditioning unit.

The next question concerns the best time of year to install a new unit. In Tampa, heat and humidity are almost year round, which means you may need to choose the time of installation carefully. The ideal time of year comes during the fall or winter, when temperatures are cooler and you don’t have as much of a need for an air conditioner. It allows the technician to work without rushing, and provides plenty of time for the unexpected to crop up.

If you’re asking “when is the time right for an air conditioning installation in Tampa?” call the experts at Ierna’s Heating & Cooling for help. We handle air conditioning installation issues of all varieties and have the experience to make sure that your new system is exactly what you need it to be.

Types of Air Conditioning in Tampa

Monday, October 14th, 2013

Weather on the Gulf Coast is notoriously warm and humid, and without a reliable air conditioning system, you’ll struggle to maintain a comfortable home. Most people think of air conditioning units as traditional central systems, with a single cooling unit connected to a series of ducts that carry the cooled air to all corners of your home. They’re effective systems and see a lot of use in the Tampa Bay area. But they’re not the only types of air conditioning in Tampa.

For example, you might consider heat pumps. A heat pump operates according to the same principles as central air conditioning. A closed system circulates refrigerant which pulls heat from the surrounding air, then disperses the heat outside the home before blowing the cooled air into the home. With a heat pump, that cycle can be reversed in the wintertime, pulling heat in from the outside air and dispersing it inside the home to help warm it. That combines heating and cooling functions into a single unit, making it easier to operate and more flexible than a traditional air conditioning unit. It’s especially effective in climates like ours, where the temperature rarely drops below 40 degrees. The downside is that heat pumps usually cost more to install that traditional air conditioning units.

Another option is a ductless mini-split system, which sets up mulitple air handler units in your home instead of one big unit. Heat pumps can be a part of mini-split systems, which entail multiple self-contained units established in different parts of the home. Each unit can be tailored to deliver a specific temperature, allowing you to heat and cool different parts of the house to your taste (and even shut off the air conditioning to some parts while keeping other parts cool and comfortable). They’re simple to set up and don’t require ductwork like central air conditioners do: a fact which ranks among their biggest assets.

If you have questions about different types of air conditioning in Tampa, or you’d like to discuss installation and repair options, call the experts at Ierna’s Heating & Cooling.  Contact us to set up an appointment today.

When to Consider Duct Cleaning

Monday, October 7th, 2013

The ducts in your Florida home are a vital part of keeping you comfortable, distributing cool and warm air. However, since you almost never see the interior of your ducts, you may not know how dirty they can get if they work for a few years without a proper cleaning. Because undamaged ducts are sealed along their length to avoid loss of pressure, there aren’t many ways for the debris build-up inside to get out… except through the vents into your living space.

Getting the ducts clean isn’t a basic job you can manage yourself. Accessing your ducts is difficult to do without causing damage to them, and simply using household cleaners and a sponge or some rags will not begin to address the problem. You’ll need specialists for this task. In Lutz, FL, the duct cleaning experts at Ierna’s Heating & Cooling have two decades of experience, so make them your first call.

You should consider duct cleaning if you haven’t had it done in a few years. It’s difficult to stop a build-up of dust, although regularly changing the air filters in your AC and furnace will slow it down. There are a few other signs that will point to the need to have work done.

One of them is an increase of dirt inside your home: if you start finding layers of dust across surfaces or on the tops of books despite your regular cleaning, then the vents may have excess dust blowing out of them.

A dirty set of ducts will lower the quality of your air, which is the most pressing reason for having them cleaned. If you’ve noticed an increase in allergy symptoms among the people in your house, or coughing, dry skin, headaches, and eye and nose irritation that seem abnormal, then you are probably experiencing a drop in air quality. Because the contaminants in your ducts can include mold and other bacterial growths—especially in the moist Florida climate—you should have the ducts cleaned as soon as possible to avoid further health problems.

Dirty ductwork can also trigger a rise in your power bills, since the build-up will force your air conditioner or furnace to work harder. A gradual increase in your monthly energy costs may be a warning that your ducts need their regular cleaning.

Our Lutz, FL duct cleaning technicians at Ierna’s Heating & Cooling use advanced methods to get your ducts back to pristine condition – call us today to schedule an appointment!
