Common Problems with Ductless Cooling Systems

March 27th, 2015 by Charlene Ierna

Ductless cooling systems have become very popular options for many homeowners, and while they are very durable and dependable systems, you may have to repair yours at some point. Some people worry that ductless systems may need more complicated repairs, but the truth is that ductless cooling repairs for your Trinity FL, home are going to be pretty similar to those of a traditional air conditioner, with a few small exceptions. However, no matter how small a problem with your ductless AC may seem, it’s important to always call for professional help. The trained experts at Ierna’s Heating & Cooling can help you with all your air conditioning repair needs, so if you are having problems with your ductless system, call us today!

Common Ductless AC Problems

Here are some of the more common problems our technicians see with ductless AC systems:

Compressor Issues

As with a traditional air conditioning system, the compressor for your ductless air conditioner resides in the outdoor cabinet with the condenser and condenser fan. The compressor pressurizes the refrigerant in your AC system, so when the compressor isn’t working correctly, you are likely to see warm air blowing from your indoor blower instead of cool air. Compressors are complex and contain refrigerant, so it’s required that a person with training and the certification to handle refrigerant perform all work.

Problems with the Indoor Blower

Each indoor blower of a ductless cooling system contains a fan, a set of coils and a small air filter. Should anything malfunction with any of these components, the operation of the blower can be affected.

Problems with the Refrigerant or Condensate Drain Line

The indoor blowers of a ductless system connect to the outdoor unit via a conduit through an exterior wall that contains a power cord, a refrigerant line and a condensate drain line. Because the condensate and refrigerant lines can be rather long, they can sometimes be more prone to developing leaks or clogging.

Bi-annual maintenance can help prevent these issues from developing, but if you are experiencing problems with your ductless cooling system in Trinity, FL, don’t hesitate to call us for repair!

How Does a Nest Thermostat Work?

March 20th, 2015 by Charlene Ierna

Never before have there been so many choices when it comes to thermostats. You can choose from simple digital thermostats that allow for precise temperature-setting all the way to high-end smart thermostats that allow you to access them remotely. One such smart thermostat that is making a tremendous impact is the Nest thermostat. The Nest brand thermostats aren’t just digital, nor are they just accessible by wi-fi; these thermostats actually learn your heating and cooling patterns and create programs on their own to help improve your comfort and energy efficiency. The experts at Ierna’s Heating & Cooling can help you with Nest thermostat installation for your Tampa property, so call us today!

How It Works

Because the Nest thermostat is a learning thermostat, has a digital interface; it also has a wheel controller that allows you to make all the temperature adjustments you need. Once the Nest is installed you’ll download the Nest app on your smart device(s) to sync the thermostat and begin making adjustments. The controls are pretty in-depth; you can control things like the speed of your HVAC fan, set a humidistat or even program adjustments should sunlight shine on the Nest thermostat at a certain time of day. The Nest system will ask for your zip code so that it can sync with the outside weather for your particular area, and if you connect Nest to your GPS, it will know when you are coming and going and will provide heating and cooling accordingly. All information is communicated via encryption over secure networks, so you don’t have to worry about security breaches.

Benefits

One of the biggest benefits the Nest thermostat offers is energy efficiency. It takes about a week for the thermostat to learn your patterns, but once it does, the device will be able to control your heating and cooling with incredible precision. Another benefit of the Nest thermostat is the convenience it offers. You won’t have to worry about constantly managing the thermostat anymore, especially once the Nest learns your patterns.

The Nest thermostat is truly a smart thermostat, and one that should only be installed by experts who can teach you how to effectively use the system.

What Constitutes the Need For an Emergency AC Call?

March 13th, 2015 by Charlene Ierna

It can sometimes be difficult to know when it’s time to place an emergency AC repair call for your Oldsmar, FL home, so the trained experts at Ierna’s Heating & Cooling have put together some examples of what would be considered an emergency need with your air conditioning:

Screeching Sound

There are two reasons your air conditioner may make a screeching sound, and one is far more serious than the other. The first, and less serious of the two reasons, is that a fan belt has become loose. The second, and more serious problem, is that your compressor is operating at dangerously high levels of pressure, which requires immediate shut-off and a repair appointment. However, diagnosing what is causing the screeching noise should always be left to experts, so if you hear this sound, shut down your system and call for help as soon as you can.

Burning Smell

A burning smell anywhere at any time is never a good sign, and it’s no different with your air conditioner. This kind of smell from you air conditioner typically indicates that an electrical problem has developed, and something has gotten so hot that it is melting. Should you detect a burning smell, turn your AC off immediately and call for service.

Popping or Buzzing Sound

Like a burning smell, a popping, buzzing or snapping sound also can indicate that an electrical problem has developed, and it’s important to turn off your AC and have it checked by an expert. It may be tempting to try and determine the issue yourself, but this is highly inadvisable. Your air conditioner is a complex electro-mechanical system, and locating and repairing an electrical problem takes training, expertise and experience.

No Air

If you have no air coming from your air conditioner, a multitude of things can be wrong, so it’s important to call for an expert right away.

Knowing when to call for emergency AC repair in Oldsmar, FL, is important for your home. If you need emergency AC service, call the people you can count on 24/7: Ierna’s Heating & Cooling.

Reasons to Consider Whole-House Dehumidifiers in Lutz

March 6th, 2015 by Charlene Ierna

It’s no secret that humidity is a big part of Florida weather, which is why having a good, reliable air conditioner is so important. However, even a new air conditioner can sometimes struggle with our humidity levels. If this is something you’ve seen in your Lutz home, you may want to consider the installation of a whole-house dehumidifier. A dehumidifier can help take the stress off your air conditioning system, but professional installation is the key. The air conditioning experts at Ierna’s Heating & Cooling have been helping customers in the Tampa area for over a decade, so if you are looking for a whole-home solution for your excess humidity, call us today!

Why Install a Whole-Home Dehumidifier?

There are a few reasons to consider installing a whole-house dehumidifier:

Allergies

Do you have allergy sufferers in your home? Mold and mildew love excess humidity, because these contaminants thrive in moist environments, and unfortunately, they can seriously agitate allergy sufferers. Another contaminant that loves excess humidity is dust mites. Dust mites also thrive in moist environments. Allowing a whole-home dehumidifier to remove the excess moisture can help improve the comfort and health of you and your family, especially those who are allergic.

Comfort

Humidity holds heat, which is why it feels sticky and uncomfortable both in the air and on your skin. When you combine humidity with air conditioning, you get a cold, clammy feeling instead of a cool, dry feeling. The whole reason to have whole-house air conditioning is to be comfortable during the summer months, so don’t let excess humidity deprive you of this comfort.

Preserve Wood and Other Products

Excess humidity can cause wood to rot, including wood inside your home, and mold and mildew to develop on furniture, linens, photos and other materials. If left to mold and/or rot, these products can be destroyed. Removing the excess humidity from the atmosphere helps preserve these items in your home.

Less Stress on Your AC

When there is excess moisture in the air, your AC has to work harder to achieve the set temperature on your thermostat. This is because when there is excess moisture in the air, your AC has to remove more heat and more moisture. A whole-house dehumidifier helps remove the excess moisture, taking this extra stress off your AC.

Excess humidity can cause a lot of problems for you, your family, your home and your AC system.

If you’d like to see what a whole-house dehumidifier can do for your home in Lutz, call the experts at Ierna’s Heating & Cooling today!

Signs You Should Consider AC Replacement in Tampa

February 27th, 2015 by Charlene Ierna

As we head out of winter toward spring, now is the ideal time to assess whether or not your current AC system in Tampa needs replacement. There are a number of factors to review when considering the replacement of your existing air conditioner, and of course, you can always (and should) seek the assistance of an Ierna’s Heating & Cooling expert to help you determine whether or not it’s time to install a new AC. What are some factors to consider? Here are a few examples:

  • Your current air conditioner uses R-22 refrigerant (Freon) – as you may very well know, R-22 refrigerant, better known by its brand name Freon, is being permanently phased out. In fact, Freon will no longer be produced at all by 2020, even for repairs. As such, if your current AC uses Freon, you will have to replace your system in the imminent future anyway. Why wait until the last minute? Get ahead of the crowd and help lower your repair costs by scheduling replacement now.
  • Your AC is more than ten years old – there are two reasons why the decade mark is important for an air conditioner: first, the average lifespan of a traditional air conditioner is 10-12 years, and second, the federal laws regarding SEER ratings were updated in 2006, which can mean you are operating a system that is not very energy efficient. High age and low energy efficiency can have a negative impact on your overall AC costs, so it is worthwhile to see how a replacement system can help improve your AC costs.
  • You have dealt with, or are facing, multiple repairs – reliability is a need with any whole-home system. If your AC has become unreliable and as a result, has needed multiple repairs or needs multiple repairs to keep running, you money may be better spent on a reliable, new system.

Replacing an existing AC system is a big undertaking, and the air conditioning professionals of Ierna’s Heating & Cooling are here to help you with every step of the process. Call us today and schedule an appointment for AC system replacement for your Tampa home!

Common Problems That Can Develop with Motorized Dampers

February 21st, 2015 by Charlene Ierna

Zone control systems are great for conserving energy and achieving customized comfort throughout your home, but occasionally the system can encounter problems. Should a problem develop with your zone control system, it’s best to call an expert for help as the mechanized damper system can be complex. The expert’s at Ierna’s Heating & Cooling have been installing and repairing zone control systems for over 10 years, and we bring this experience to every zone control system repair we have, including the New Port Richey area.

How a Zone Control System Works

Zone control systems are actually a series of dampers installed directly into your supply ducts. Once you and your technician have established the zones in your home, the technician will install the dampers according to the zone plan. The dampers are wired to a main control panel to which each zone’s thermostat is also wired. The main control panel can then maintain each zone’s set temperature by controlling the opening and closing of each damper.

Type of Problems

Here are some of the kinds of problems that can develop with a zone control system:

Problems with a zone thermostat – thermostats can malfunction due to dust and dirt on the instrumentation, incorrect calibration or dying batteries. Thermostats should always be the first place to look when encountering problems with your zone system as thermostats are the control centers for each zone.

Problems with the dampers – sometimes the dampers of the motorized damper component can become stuck, prohibiting the damper from opening and closing as needed. A technician will know how to get into your supply ductwork to determine and repair the problematic damper.

Problems with the main control panel – the main control panel in the system is responsible for taking the information from each zone’s thermostat and controlling the operation of the dampers so that the set temperatures can be maintained. Should there be issues with wiring, electricity or anything else that can interfere with the correct operation of the control panel, problems will likely develop with the system.

As you can see, there is a level of complication to a zone control system, which is why hiring an expert for your zone control system repair in New Port Richey is always the best option.

Some of the Unusual Movies Released for Valentine’s Day

February 14th, 2015 by Charlene Ierna

Hollywood has always tried to match movies up to the seasons to draw droves of viewers to the theaters: October is packed with fright-offerings, while the winter holidays skew toward warm and pleasing family films (as well as Oscar hopefuls). Valentine’s Day falls in an odd spot when it comes to the movie release calendar, however, since February tends to be a slower time for the film industry. The studios are as likely to slot strange movies that don’t fit anywhere else in their annual schedules into the Valentine’s Day weekend as they are films with powerful romantic appeal.

So, while the second weekend of February has featured hugely successful romantic comedies like Hitch, The Wedding Singer, and (of course) Valentine’s Day, some truly weird choices have debuted in this weekend as well. And a few have even gone on to tremendous success despite the bizarre match with the holiday. Here are a couple of the odder Valentine’s Day movie releases:

  • Dracula (1931): Yes, this Halloween perennial and the start of Universal Studio’s Classic Monsters actually came out on Valentine’s Day! But perhaps this makes some sense, as the Dracula legend has often received a “doomed lover” approach in the many years since Bela Lugosi made the aristocratic vampire a screen icon.
  • The Silence of the Lambs (1991): Does any film seem less appropriate for Valentine’s Day than this unnerving and sometimes very violent psychological thriller? What’s even more astonishing than the film’s release date is that The Silence of the Lambs eventually nabbed the Oscar for Best Picture, an almost unheard of occurrence for a movie released so early in the year.
  • Daredevil (2003): This Marvel comic adaptation featuring Ben Affleck as a blind superhero does contain a romantic subplot, but the stronger connection to Valentine’s Day may just be that Daredevil wears a bright red costume.
  • A Good Day to Die Hard (2013): The least successful of the Die Hard film franchise, this is an excellent example of a studio dropping a film into a weekend where it doesn’t fit in the hopes that it works as counter-programming. (It didn’t.)
  • Wayne’s World (1992): Now here is an example of counter-programming that clicked with audiences. This comedy based on a Saturday Night Live sketch turned into one of that year’s biggest hits and spawned a sequel.

Whether you celebrate Valentine’s Day with a trip to the movie theater, or you have your own special plans, everyone here at Ierna Heating & Cooling hopes you and your loved ones have a wonderful weekend.

What Is Duct Testing and Why Is It Important?

February 5th, 2015 by Charlene Ierna

Before warm or cool air moves into your home from the heating or air conditioning system, it first traverses through a set of ducts that should provide a clear and efficient pathway through which air can travel—in theory. Unfortunately, these ducts aren’t always designed as well as they could be. Sometimes, installation flaws account for air leaks or allow heat to escape or enter the ducts undesirably. But a duct system may also develop leaks over time due to the pressure of the air it contains every day.

Now, don’t think that this is a rare occurrence that only happens in some households. According to the U.S. Department of Energy, most duct systems have major or minor leaks and flaws that account for an estimated 30% heating and cooling loss in the typical home. Any duct system can run into trouble over time, and it’s actually likely that yours is causing some issues of which you are unaware. Thankfully, you can schedule duct testing with a trained professional who can determine whether there are weak points in your ducts, the exact location of leaks, and what should be done about it.

When ducts leak air, it affects multiple areas of your home and your daily life. For one, a leaky duct system keeps you less comfortable. There are likely to be hot and cold spots around the home and your HVAC system will take longer to get the entire home to the right temperature. You’re less likely to notice the difference if the leak has progressed slowly over time (or if it’s always been there), but you may be spending hundreds more on heating and air conditioning every year than you would without any leaks at all. Furthermore, your HVAC system is working way harder than it should have to, which could mean that parts of your HVAC system will fail too soon if your duct system doesn’t receive attention.

Duct testing includes a thorough examination of your ductwork. Testing may include high-tech viewing and recording equipment, air pressure tests, and possibly a look at your HVAC equipment to determine how your ductwork may contribute to irregularities. Experts will then recommend services to correct the problem areas, including duct sealing, repairs, or even a bit of design work.

Common Problems with AC Condenser Unit

January 29th, 2015 by Charlene Ierna

Your air conditioning system has many components, but there are three main ones that do the lion’s share of the work: the compressor, condenser and the evaporator. Today we’re going to focus on the condenser and its role in the air conditioning process.

What Is the Condenser?

The condenser is a component housed in your outdoor unit with the compressor. When the refrigerant has been compressed, it makes its way into the condenser, where a set of coils helps the refrigerant release its heat as it flows through them. There is also a condenser fan which helps to further cool the refrigerant by sucking up the heat from the refrigerant and blowing it into the outdoor air. Without the condenser, the refrigerant would not be able to cool properly.

What Can Go Wrong with a Condenser?

There are a few things that can malfunction with a condenser and cause operational issues with your air conditioner. First, the aluminum fins of the coils are very easily bent; if a number of them are bent the wrong way, the air that needs to pass through the fins can be restricted and as a result, inhibit the cooling process. A second common problem that can develop with the condenser is dirty coils. When a layer of dirt and dust forms on the coils, it can act as an insulator that traps in the heat instead of allowing the coils to release it. In turn, this can result in warm air blowing into your home, among other problems. Refrigerant leaks are another common type of problem that can develop with the condenser. A refrigerant leak in the condenser will lower the amount of refrigerant in the system, which creates an imbalance; as such, the leak has to be repaired by an expert. Lastly, the condenser fan can develop problems: electrical issues with wiring and the capacitor, fan motor problems and/or problems with bent or loose fan blades.

The condenser is a key component to the successful operation of your air conditioner and will require the help of an expert.

What Makes a Single Zone System the Best Choice for a Small Home or Room Addition?

January 22nd, 2015 by Charlene Ierna

Expanding your home is a big task, and one that requires serious HVAC work. But what if you could avoid installing ductwork into your home, and still have heating and cooling that matches the rest of your home? You can, with a Mitsubishi single zone ductless system in Wesley Chapel. With a single zone system, you can add the needed heating and cooling to a new addition without having to spend thousands on extending your home’s ductwork. Or, if you have a room in your home that is notoriously too hot during summer or too cold during winter, you can easily add supplemental warm air or cold air to that space with a single zone unit.

How Does It Work?

A single zone ductless system works the same as a multi-zone system, just on a smaller scale. With a single zone, you still have an outdoor unit and an indoor blower, but you also get a wireless remote thermostat to program the heating and cooling. The in- and outdoor units are connected by a conduit through which the refrigerant flows, and when the indoor unit turns on, the heating or cooling process begins.

Special Attributes of the Mitsubishi Single Zone System

Inverter Technology

One specialized detail of the Mitsubishi Single Zone System is that it comes equipped with Inverter technology. The technology allows the speed of the compressor to work on a varied basis in accordance with heating and cooling need of the room. The result is even cooling that is energy efficient.

Extra Filtration

Most indoor ductless units come with two filters; the Mitsubishi Single Zone System comes with three. Triple filters help capture a number of airborne contaminants including allergens, viruses and bacteria.

Quiet Operation

The Mitsubishi Single Zone System has been designed with quiet in mind. The blowers have compartmentalized components which helps reduce operation noise considerably.

A single zone ductless system may be just what you need for a new expansion or intemperate room in your home, so contact Ierna’s Heating & Cooling today!
