Lutz Heating Repair Guide: Cracked Heat Exchangers

December 11th, 2014 by Charlene Ierna

There are a lot of urban legends about the dangers of certain kinds of heating systems, and while there is some truth to certain problems, there are only a few truly dangerous situations that can develop with your furnace. One of these is operating a furnace with a cracked heat exchanger. During annual heating maintenance, your heat exchanger is inspected for corrosion, rust and cracks for safety and function purposes; this is one of many reasons why it’s important to schedule annual maintenance for your furnace. First, we’ll explain what a heat exchanger is.

What Is a Heat Exchanger?

A heat exchanger is the component in your furnace that helps generate the heat that is blown into your home; it also is the component that keeps the toxic combustion byproducts of your furnace’s burner from entering your home. The heat exchanger is a moderately-size serpentine tube that is open on both ends. When the burner ignites, it heats the heat exchanger; while the heat generates, combustion byproducts like noxious gases and soot enter the bottom of the heat exchanger and flow up. The top of the heat exchanger is connected directly to your furnace’s flue, and the toxic byproducts flow directly outside. The warm air generated outside the heat exchanger is blown into your ductwork.

What Happens With a Cracked Heat Exchanger?

The main problem that can occur with a cracked heat exchanger is that the toxic byproducts – including gases like carbon monoxide – can escape during operation and be blown into your living spaces. Additional problems can be poor performance and an inability of the system to meet your heating needs.

Why Does a Heat Exchanger Crack?

One of the main causes of cracking is age. The average heat exchanger has a lifespan of 15-18 years, similar to that of the lifespan of your furnace. Over time, the constant heating and cooling of the heat exchanger’s metal can weaken it, eventually causing cracking. A second cause of cracking is the development of rust or corrosion on the heat exchanger; corrosion can make a heat exchanger prone to cracking.

Heat exchangers cannot be repaired if they are cracked; replacement is required to repair your heating in Lutz.

Schedule Maintenance Today for Your Light Commercial Heating System

December 4th, 2014 by Charlene Ierna

Your light commercial heating system won’t run forever, but it can last well over a decade with the proper maintenance. Here in Tampa, it’s not often that we need to switch into heating mode. Because of this, you may forget that maintenance is vital to the performance of a heater, just as it is with an air conditioner. If it’s been a couple of years or more since your heater has gotten a tune up, there’s certainly a chance that something may go wrong.

Professional maintenance is the best way to protect your system from damage or from a premature breakdown. If you schedule maintenance today, it’s unlikely that you’ll notice any further repair needs this heating season. Besides, light commercial heating system maintenance may increase the lifespan of your unit and improve efficiency. Standard wear and tear on your commercial system means the parts end up using a lot of energy to run, but a tune up can save you a lot over time.

Can’t I Perform Maintenance On My Own?

Maintenance is not something that just anyone can perform. Professionals simply know the ins and outs of heating systems to better protect and prolong the life of your system. Most heating technicians have years of experience and training, and understand what to look for when inspecting to damage and making minor adjustments. Without the proper skills, you may clean a component using the incorrect procedures or gloss over an important repair need. Always trust heating experts to make sure your system is in top shape before they leave.

During professional maintenance, a technician cleans and adjusts various components of the system and thoroughly inspects each and every part. Even a light commercial heating system may be quite large, and some hidden parts could be in trouble. Your technician will let you know if a component needs repair so that you can schedule service now, before a major problem leads to a breakdown on the day your business needs heating the most.

Contact Ierna’s Heating & Cooling to learn more about how you can improve comfort on your commercial property by scheduling annual light commercial heating system maintenance in Tampa.

10 Facts You Should Know about Thanksgiving

November 27th, 2014 by Charlene Ierna

Thanksgiving has been celebrated as an official holiday in the United States for over 150 years, so you may think you understand all there is to know about this family feast. Most of us have heard the story of the pilgrims’ first Thanksgiving in 1621 after arriving in North America on the Mayflower. But did you know that only about half of the people on this ship were actually pilgrims? This fact is one of ten things that may actually surprise you about the Thanksgiving tradition!

  1. Although we often consider Thanksgiving a holiday unique to the United States, many other countries and cultures celebrate their own set of harvest-time and thanksgiving traditions. In Korea, Chu-Sok (or “fall evening”) is put on in remembrance of forefathers on August 15th of every year. Brazil celebrates a contemporary version of the U.S. holiday. Chinese, Roman, and Jewish cultures all have a history of harvest celebrations as well.
  2. President Harry S. Truman began the tradition of a ceremony held before Thanksgiving during which the president receives a turkey. George H.W. Bush was the first to pardon the turkey instead of eating it.
  3. In Minnesota alone, farmers raise over 40 million turkeys a year. In fact, U.S. farmers produce about one turkey for every one person in the country.
  4. According to the New England Journal of Medicine, the average American will gain about one to two pounds every year during the holiday season.
  5. On the other hand, turkey is naturally high in protein and has been known to support and boost immune systems to protect against illness and speed up healing. So feast on!
  6. Abraham Lincoln issued a “Thanksgiving Proclamation” in 1863, but a woman named Sarah Josepha Hale can be credited with the idea. While Thanksgiving had been celebrated at different times of year in many areas of the U.S. for years, it was Hale, prominent magazine editor and author of the rhyme “Mary Had a Little Lamb,” who urged Lincoln to finally establish the national event.
  7. President Franklin D Roosevelt once tried to change the date of Thanksgiving to the second-to-last Thursday of the month in order to extend the holiday shopping season and boost the economy.
  8. Only about half of the people on the Mayflower were what we would consider today as “Pilgrims.” The other (approximately) 50 people were simply trying to find a way over to the New World.
  9. Gobble, gobble! Click, click? While male turkeys make a gobbling noise, females (hens) do not; it’s often described as a clicking.
  10. Even though we celebrate Thanksgiving on the last Thursday of November, the month of June has been declared National Turkey Lovers’ Month by the National Turkey Federation so you can continue the celebration in the summer as well!

From our family here at Ierna Air, we’d like to wish you and yours a very Happy Thanksgiving!

How Regular Heating Maintenance Can Save You Money

November 17th, 2014 by Charlene Ierna

A lot of homeowners wait to schedule heating maintenance until something goes wrong. This is understandable, since no one really wants to deal with the hassle of maintaining their heating system if they don’t have to. The problem with this method is that it not only harms the heating system through negligence, but wastes money as well. Regular heating maintenance can actually save you quite a bit of money. Read on to find out how.

Combating Wear and Tear

Problems with your heating system don’t just happen out of nowhere. There is always a decline from working properly to the point of breaking. Homeowners usually don’t see this happening, so they don’t see the need to call an HVAC technician until something seems to be wrong. As this wear and tear accumulates on parts, however, those parts will decrease in effectiveness. This will cause the system to consume more energy, as it will have to work longer to produce the same results. This increased time of operation translates to a higher heating bill for you. Regular heating maintenance can combat this process by finding and replacing parts that are becoming a drag on your system.

Stopping Leaks

Forced air heating systems lose almost 30% of their heat on average to duct leaks. That’s almost one-third of your total heat output that is being wasted every time you turn the heat on. Boiler systems and heat pumps experience leaks of a more serious kind, draining water pressure and refrigerant respectively. Beyond simply wasting money, these leaks can prevent the system from circulating heat at all, as well as causing water damage. Just like the normal wear and tear, these leaks often go unnoticed until the present a serious problem to the rest of the system. Regular heating maintenance is the best way to find and seal these leaks before they can do far more damage.

If you haven’t scheduled heating maintenance in a while, call Ierna’s Heating and Cooling. We provide heating maintenance services throughout Wesley Chapel.

Types of Problems Discovered During Duct Testing

November 10th, 2014 by Charlene Ierna

Because the ductwork in a home is primarily hidden behind construction material such as drywall and flooring, homeowners are rarely conscious of the condition of their ventilation system. If the integrity of ductwork becomes compromised, however, it will result in serious problems for a home’s HVAC system: a loss of airflow from the vents, insufficient heating and cooling power, increased energy bills, and the infiltration of contamination into the ducts that will then flow into the living spaces.

If you suspect that your ductwork may have damage that requires repairs, the best way to know for certain—and to find out the extent and type of repairs necessary—is to call for professional duct testing. Our indoor air quality team at Ierna’s Heating & Cooling performs duct testing in Riverview, FL and the surrounding areas, and we offer numerous repair services to fix the problems afterwards. Call us today to schedule testing for your ductwork.

What professional duct testing may discover

During duct testing, our team seals up all the registers in your home and then places the entirety of the ventilation system under high air pressure. We then measure the pressure level to see how far it drops and use sensing devices to find places where air is escaping from the ducts. This tells us what is wrong, where it is occurring, and its extent.

One of the most common issues that duct testing uncovers is poor joints and connectors. Sometimes this is the fault of inferior installation work, which is one of the reasons that you should always employ professionals when you need to have new ducts installation or replacements. Custom ductwork design can help make for a more seamless fit during installation.

Poor sealing and broken joints along the ducts are also common problems that duct testing will discover. Another issue that can occur, and is often a problem for a humid place like Florida, is holes developing in the ducts due to corrosion or mold and mildew growth. If this is a problem for your ducts, you will also want to have professional cleaning done or the installation of UV germicidal lights to combat future problems.

Along with providing high quality duct testing in Riverview, FL, Ierna’s Heating & Cooling has full services for indoor air quality that includes duct sealing, custom duct designing, and installation of UV germicidal lights to get rid of mold infiltrations.

When you suspect that your ducts need help, contact us for the testing that will tell you what needs to be done—and let us take it from there.

Reasons to Schedule Prompt Dehumidifier Repair

November 3rd, 2014 by Charlene Ierna

If you’re like many people in Lutz, you chose to install your whole-home dehumidifier in order to keep you and your family more comfortable on the most humid of days. Humidity leaves you feeling hot and sticky due to the excess moisture in the air. Moisture means that your body cannot evaporate sweat very easily, making you feel as though the temperature is hotter than it actually is. While your dehumidifier is a great help, it could potentially break down at some point, and you should pay attention to the signs of a malfunctioning system before it’s too late.

Benefits of Dehumidifiers

Dehumidifiers do more than keep you feeling cool and comfortable on a humid day. They can also prevent mold development in your home. Moisture creates an ideal environment for mold and mildew to thrive. As mold spores circulate through the ducts and move into the air you breathe, it can aggravate allergies or respiratory problems. Mold can also cause damage to your home, resulting in some costly renovations. While your air conditioner can remove some humidity from the air, a whole-home dehumidifier offers additional support to pull a large percentage of moisture from the air.

Signs of Dehumidifier Problems

Dehumidifiers are known for fairly quiet operation, so any loud noises should alert you to a problem with the system. You may also learn of a problem with your dehumidifier if the conditions in your home worsen, or if you start to notice water spots or leaks around the area of the unit. Whatever the repair need, it will only continue to worsen, leading to the possibility of no humidity control at all or water leaking into your home and damaging your belongings.

Schedule Maintenance and Repairs with Indoor Air Quality Experts

It’s important to schedule maintenance every year to clean and inspect your dehumidifier and make sure water drains properly and that all of the parts work as they are supposed to. This may be done as a part of your regular annual HVAC maintenance if you work with indoor air quality specialists.

Why Ask a Professional for Help Selecting a New Air Filter

October 27th, 2014 by Charlene Ierna

With today’s current concerns about maintaining indoor air quality in homes and businesses, air filtration systems are becoming more popular. It’s easy to see why: a properly sized and installed mechanical air filter fit into the HVAC system of a building will remove around 99% of the particles that can contaminate the air inside living and working spaces, all without placing any extra drain on energy and requiring only occasional maintenance to change the filters.

It sounds simple… but actually choosing and installing a filter isn’t simple at all unless you have professional training. To do this job you must have indoor air quality experts assist you.

Why do I need professionals for this job?

There is no such thing as a “one size fits all” air filtration system for a home. You may have heard about HEPA filters, which are among the most effective of all mechanical air filters available. However, these filters aren’t necessarily the best for your home; they are designed for use with powerful blowers that send immense volumes of air through a large ventilation network. If you select a HEPA filter with a very high MERV rating (the rating that indicates how effective a filter is at trapping particles) for your house, you would probably end up blocking the air trying to pass through the HVAC system along with the contaminating particles. This would not only mean a drop in airflow from the room vents, but also an immense strain placed on the heater/air conditioner and skyrocketing bills. Picking a filter just because it’s powerful is a recipe for an uncomfortable home—and energy bills that are uncomfortable to look at!

Professionals will know how to fit your home’s HVAC system with a filter that’s the ideal size and MERV rating for efficiency. They will also know what sort of contamination is causing the most trouble for your home, and choose an air filtration system that will address it specifically. You don’t want to spend money on a filter that tries to solve a problem you don’t have!

Finally, you must have professionals integrate the air filtration system into your ductwork so that the new filters work properly with your air conditioner and heater. Poor installation will mean a filter that permits contamination through anyway, which isn’t much better than no filter at all.

The Best Ways to Improve Indoor Air Quality in Land O’ Lakes

October 20th, 2014 by Charlene Ierna

Here in Land O’ Lakes, proper insulation and sealing is key to a comfortable home during the warm, humid months. Unfortunately, this can create some problems for the air quality indoors, as the air in a home with poor ventilation may begin to collect dust and allergens and contribute to mold and bacteria growth.

At Ierna’s Heating & Cooling, we have the right type of system to remove any unwanted particles and microorganisms from the air in your Land O’ Lakes home, including air cleaners, dehumidifiers, and UV germicidal lights. This guide can help you learn a bit more about how these systems help to eliminate indoor air pollutants and improve the air quality.

Air Cleaners

One of the most widely used methods to control indoor air quality is with a mechanical air filter. These filters work with your HVAC system to strain larger particles that may otherwise pass through the ducts and back into your house. And while your current filter may seem to be working well, a filter with a higher MERV rating may trap more pollutants. For even greater protection, an electronic filter can also work with your HVAC system, using ions to filter out even smaller undesirable particles.

Dehumidifiers

Air conditioners are effective in removing some moisture from the air, but sometimes they need a little extra help to keep your home as comfortable as possible. A dehumidifier takes away that sticky feeling that usually accompanies high moisture levels in the air, and it can also help with the quality of your air. Moisture allows mold to grow in or around the home, but a whole-home dehumidifier can eliminate this issue in many areas of the house.

UV Germicidal Lights

Technicians can also install UV germicidal lights in the ducts, which destroy germs suck as bacteria and viruses that could make your family members feel sick. Ultraviolet light damages organic matter when it comes into contact with it. While this usually has only a small effect on humans who are exposed to the sun for periods of time, it can sterilize and eradicate some microorganisms for good. This system works well for people with compromised immune systems.

When you need to find the right system to control the indoor air quality in Land O’ Lakes, call Ierna’s Heating & Cooling now!

What Type of HVAC System is Right for My Riverview Mobile Home?

October 13th, 2014 by Charlene Ierna

You care about comfort in your mobile home, but it can be difficult to find an HVAC system that is the right size. Most heating and air conditioning systems are designed for larger homes, and indoor installation can take up a lot of space. That’s why the folks at Ierna’s Heating & Cooling recommend packaged HVAC systems for mobile homes in Riverview. Bryant offers a full line of packaged air conditioners and heat pumps that are great for cooling and heating mobile homes throughout the year. Learn more about your options in this quick guide.

Bryant Packaged Air Conditioners

Most air conditioners have two main components, an indoor evaporator unit and an outside condenser unit. However, your mobile home may not have space for indoor installation, which is why a packaged air conditioner may be just right for you. Packaged air conditioners combine every component of a central air conditioner into a single cabinet, so it can sit right outside your mobile home and a technician can connect it directly to the ducts.

If you are concerned about the initial cost, Bryant offers an efficient entry-level Legacy series air conditioner or a mid-range Preferred series unit. But for even greater efficiency, you may consider the 15 SEER Evolution packaged AC system to significantly cut cooling costs.

Bryant Packaged Heat Pumps

Alternatively, you might consider a packaged heat pump. Bryant also offers these systems from either the Legacy, Preferred, or Evolution series. A heat pump is a particularly unique system in that it can provide efficient heating and cooling. In the cooling season, it works just like an AC, using refrigerant to absorb heat from your home and circulate cool air through the ducts. When you need heating, refrigerant flows in reverse, pulling heat from the outside air to move into your home. This makes it extremely efficient for heating as it only moves heat rather than generating. And while it may not work well for heating if temperatures drop too low, it’s perfect for the Florida weather.

The specialists at Ierna’s Heating & Cooling are proud installers of Brant HVAC systems for mobile homes in Riverview. Call us today!

What Types of Homes Benefit from Zone Control?

October 6th, 2014 by Charlene Ierna

Energy efficiency is a priority for most households, and if you’ve been looking for a way to make your home more energy efficient this winter, there is a great option worth considering: a zone control system. A zone control system works within your ductwork, controlling the flow of air to each designated zone. When installed by a professionals, a zone control system in Tampa can offer you a number of benefits, as we’ll explain below. For any upgrade to your heating system, make sure to call the professionals you can count on: Ierna’s Heating & Cooling.

What Types of Homes Benefit from Zone Control?

Our technician are asked this question a lot, and in general, just about any home can benefit from the installation of a zone control system. However, certain types of homes may find a zone control system especially beneficial:

  • Multi-storied homes
  • Homes with multiple wings/hallways
  • Homes with vaulted ceilings
  • Homes with floor-to-ceiling windows
  • Homes with open loft spaces

How Does a Zone Control System Work?

A zone control system consists of a series of motorized dampers that are installed into your supply ducts. The zones are designated by you before installation, and once the dampers are installed, they are wired into a main control panel. The thermostats for each zone are connected to the main control panel, and based on the set temperature, the control panel then instructs the dampers when to open and close in order to maintain the temperatures in the zones.

What Are the Benefits of a Zone Control System?

There are several benefits of a zone control system that make them worth consideration:

  • Better energy efficiency – a zone control system allows you to heat only what you need. You can reduce or even turn off heating to areas of your home that are unoccupied or unused, and you can control the heating the in the areas in which you spend the most time. This helps with overall better energy efficiency.
  • Better comfort – a zone control system gives you total control over how much heat you use. You can fully customize your comfort throughout your home.
  • Less wear on your system – when you reduce the amount of heating you need with use of a zone control system, your system operates less; this helps put less wear on your system.

A zone control system can be a great energy-saving option for just about any home.

If you are interested in knowing what a zone control system in Tampa can do for you, call Ierna’s Heating & Cooling today and schedule an appointment with one of our specialists.
