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.

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.

How an Ultraviolet Light Works in Your Home

September 29th, 2014 by Charlene Ierna

If you have concerns about biological contaminants in your indoor air, one of the best tools to fight these types of particles is ultraviolet (UV) lighting. Also known as UV germicidal lights, these lights act as air purifiers by destroying biological contaminants. UV germicidal lights in Lutz are over 99.9% effective, and are safe for home use. The NATE and EPA certified indoor air quality specialists at Ierna’s Heating & Cooling can ensure professional installation of UV lights, so call us today.

How Does Ultraviolet (UV) Light Work?

UV lights emit radiation in the form of UV-C rays. These types of rays have the ability to destroy the DNA in biological contaminants and the life-sustaining proteins that help keep cells alive. This dual action not only kills the cell, it keeps it from replicating. As such, UV germicidal lighting doesn’t just get rid of biological contaminants: it eradicates them.

What Are the Benefits of UV Germicidal Lights?

There are several benefits to using UV light in your HVAC system:

  • Improved indoor air quality – by removing biological pollutants, you can increase the quality of your indoor air.
  • Stops mold and bacteria growth – the anti-microbial effect on contaminants helps stop biological growth.
  • Eliminates odors – UV lights kill the contaminants that can create unpleasant odors.
  • Generates negative hydroxyl ions – negative hydroxyl ions are natural compounds that remove pollutants from the air.
  • Flexible placement – UV lights can fit virtually anywhere, but the most common placement for them is in vents and over the evaporator coils.

Two items to note about UV lights are that they do not capture anything like a mechanical or electronic air cleaner will, and they do not draw particles to them. For biological contaminants to be destroyed, the contaminants have to pass within the area of radiation.

If you are looking to remove the biological contaminants in your home, UV germicidal lights in Lutz may be just what you need.

For professional installation of UV germicidal lights, call Ierna’s Heating & Cooling and schedule an appointment with one of our indoor air quality experts.

How Duct Cleaning Improves AC Efficiency

September 22nd, 2014 by Charlene Ierna

Just because you cannot see the ductwork in the walls of your home doesn’t mean you shouldn’t think about them. The ventilation system of your house is what allows the proper distribution of cooled air from your air conditioner throughout the rooms. When the ducts become dirty (and they will become dirty over time, no matter how clean your home is) they will interfere with your AC’s efficiency, leading to higher bills. Regular cleaning is necessary to make sure that your air conditioning system doesn’t face too much resistance while doing its job.

If you have noticed an increase in your utility bills during times when the AC runs regularly, you may have clogged ducts. Open up one of the vent covers and reach inside with a digital camera and take a snapshot; if the image shows heavy dust, dirt, and lint along the inside of the ducts, you need to schedule professional duct cleaning right away. Call Ierna’s Heating & Cooling and speak to our Wesley Chapel, FL duct cleaning specialists to arrange for the work.

Why clean ducts equals a more efficient AC

All air conditioners are forced-air systems that blow out conditioned air into the rooms. Unless you have a ductless mini split air conditioner, your AC must send the air through a network of ducts. As with any kind of airflow, the air from an AC needs to meet as little resistance as possible. Only a small layer of dust will start to add friction against the movement of air, and this means the air conditioner must drain additional electricity to overcome the resistance. If the dust layer continues to develop, the friction will increase. It will also start to clog up the air filter of the AC, which will choke off the airflow into the cabinet and severely affect system efficiency.

There isn’t much you can do to prevent ductwork from becoming dirty. You can slow down the process by changing or cleaning the air filter monthly. However, dust will naturally enter the ductwork through the return air vents and begin to accrue inside the ventilation system. Usually it takes about two years for the buildup to begin to affect an air conditioner’s performance. If more than two years has passed since your last air duct cleaning, consider scheduling the service soon to protect AC efficiency and reliability.

Ierna’s Heating & Cooling provides duct cleaning in Wesley Chapel, FL and the surrounding areas. We use the comprehensive Rotobrush technology to make sure your ductwork receives a thorough cleaning without sustaining any damage.

Call Ierna’s Heating & Cooling today to schedule your regular duct cleaning so you can enjoy energy-saving performance from your air conditioner.

How a Faulty Thermostat Can Damage Your AC

September 15th, 2014 by Charlene Ierna

The thermostat is one of the most vital parts of an air conditioning system, one that people interact with on an almost daily basis, and one of the few parts of an AC that sits in plain sight—yet few homeowners ever give it much thought. If the thermostat malfunctions, your home’s cooling and the system that takes care of it could be in for trouble.

When a malfunctioning thermostat causes problems, you need to call for expert air conditioning repair in Tampa Bay, FL from a company with NATE-certified technicians and the training to handle any necessary work. You need to call Ierna’s Heating & Cooling. We have same day emergency service, so don’t hesitate to call when you need that air conditioner repair done now.

Some AC problems due to a malfunctioning thermostat

When a thermostat develops repair problems, it will often lose its connection to the air conditioner. In such cases, although you will need repair technicians to fix the thermostat, you shouldn’t have damage to the AC itself that will need work.

However, there are ways that a thermostat can go wrong that will cause serious problems for the air conditioner. One of them is when a miscalibration in the thermostat leads to a short-cycling AC. “Short-cycling” is when an air conditioner’s cooling cycle turns off before it can finish: the compressor begins its work, and then abruptly shuts off because the thermostat has incorrectly determined that it has reached its target temperature. But soon after the compressor turns off, it will turn back on again, starting the process anew.

The reason this will turn into a significant AC repair problem is because it places severe stress on the compressor, the most valuable part of an air conditioner and the most expensive component to replace should it fail. The start-stop action of short-cycling is one of the worst things that a compressor can undergo. The stress isn’t limited to the compressor either: it will also affect the motors and cause them to burn out.

The wires in the thermostat that connect to the AC can fail in a way that will cause the air conditioner’s fan to run without stop, and this is also potentially very damaging for the AC as it places heavy strain on the fan motor.

Issues with the thermostat often initially appear as problems in other parts of the AC (for example, short cycling can occur because of a loss of refrigerant), so you may not know that the thermostat is the cause at the beginning. However, your repair technician can track the source of the malfunction, so whenever you detect anything amiss with your cooling system, get on the phone and call a reputable repair contractor.

You can also call us for upgrades to your current thermostat to a more efficient model.

Why Indoor Air Quality Matters

September 8th, 2014 by Charlene Ierna

Being comfortable in your home isn’t just about temperature – it’s about the quality of your indoor air. Poor indoor air can contribute to allergy problems, health issues and problems with your air conditioner. There are a number of products on the market that can help you achieve good indoor air quality in Land O’Lakes, and Ierna’s can provide the professional installation you need for all upgrades to your air conditioning system.

Common Air Contaminants

There are a number of common air contaminants that can affect your indoor air quality:

  • VOCs (volatile organic compounds) – VOCs are carbon-based chemicals that emit gases from certain types of solids and/or liquids, many of them household items. Effects can be short- or long-term. Typical substances that emit VOCs are paint, paint strippers, cleaning supplies, pesticides, glues and adhesives.

 

  • Carbon monoxide/dioxide and nitrogen dioxide – these types of fumes typically enter the air in your living spaces from large appliances like furnaces and hot water heaters, which use combustible fuels such as oil and gas. Wood-burning stoves and kerosene heaters can also contribute to this kind of indoor air pollution.

 

  • Respirable particulates (RSPs) – RSPs are small particles from aerosols, tobacco products, unvented kerosene and gas heaters and wood combustion that can penetrate and linger in the deeper part of your lungs (the non-ciliated portions). This can cause serious problems for those with chronic respiratory disorders like asthma and COPD, and can also cause ongoing irritation for others, including coughing and wheezing.

 

  • Biological contaminants – mold, mildew, fungus, algae, dust mites, allergens, bacteria and viruses are all biological contaminants that can reside, develop and grow within your air conditioning system and become a part of your indoor air.

 

Health Problems That Can Ensue from Poor Indoor Air Quality

  • Allergic reactions
  • Respiratory attacks (with disorders like asthma)
  • Respiratory issues (coughing, wheezing)
  • Headaches
  • Nose bleeds
  • Nasal congestion
  • Sore throat
  • Lethargy
  • Fatigue
  • Muscle pain

As you can see, there can be a lot going on with your indoor air, and it may make you unhealthy.

If you are concerned about the quality of your indoor air, call Ierna’s Heating & Cooling today and schedule an appointment with one of our experts.

What’s the Difference between Electronic and Mechanical Air Cleaners?

September 1st, 2014 by Charlene Ierna

Protecting your home’s indoor air quality often requires special effort if you want both healthy air and an efficient heating and cooling system. One of the best methods to have both is to install an air cleaner for your HVAC system. These cleaners remove contaminating particles from the air that circulates through the HVAC system while providing minimal resistance to airflow. With the right air cleaner installed with the assistance of a professional, you can have close to 100% of the unwanted pollutants in your air removed.

It’s vital that you have an indoor air quality specialists help you with finding and installing an air cleaner. The wrong size and type of air cleaner can end up impairing your HVAC system or failing to adequately eliminate the particles you need filtered.

At Ierna’s Heating & Cooling, we are proud of the service we provide in improving indoor air quality in New Port Richey, FL with air cleaners. There are different types of air cleaners that we install, but most fall into two broad groups: mechanical or electrical.

Mechanical air cleaners

A mechanical air cleaner uses a mesh of material, usually fiberglass fibers, to trap particles passing through them. They both impede the particles and attract them to the surface of the fibers, where they become lodged. The most common type of mechanical air cleaner is the HEPA (high energy particulate air) filter. However, these are uncommon in homes because they can create too much blockage against airflow. Professionals will find a mechanical filter that will trap particles without creating too much air resistance.

Electronic air cleaners

Unlike mechanical air cleaners, electronic cleaners are not filters at all. They instead create an electric field that ionizes particles that pass through it. When the particles are ionized, they are drawn down to a pair of plates on the cleaner and trapped there. Electronic air cleaners require an external power source to run, but they are often necessary because they can remove contamination that is too small for a mechanical filter to catch.

Find the right air cleaner for you

Mechanical air filters and electronic air cleaners are not the only option you have for cleansing the air that flows through your HVAC system: you can also have UV lights installed or other filtration systems. There are also HVAC systems designed specifically to handle HEPA filters. There’s also no reason you can’t have more than one type of cleaner or filter installed.

Call Ierna’s Heating & Cooling to talk to our specialists in indoor air quality, and they will help you sort through the options available and find the air cleaners in New Richey, FL.

Tampa Air Conditioning Guide: Is Ductless Cooling Right for My Home?

August 25th, 2014 by Charlene Ierna

Many people are familiar with traditional central air conditioning systems that blow cool air through the vents in a home. Central air conditioning is installed in two parts, an indoor unit and an outdoor unit. The inside evaporator unit removes heat from the air, as a blower fan blows cool air into the home through the ductwork. Heat then releases outside at the condenser unit. However, some homes are not built with ductwork, and homeowners may look for another solution. While ductwork installation may be a possibility, this takes up time and involves extensive renovations.

Ductless cooling provides whole-home cooling without the need for a built-in home air distribution system. Ductless cooling uses the same components to cool a home as central air conditioner, but the outdoor unit is connected to multiple indoor air handlers. Each handler contains an evaporator as well as a blower fan to distribute air. These units are mounted high on the wall or suspended from the ceiling, so cool air blows directly into the room.

Who Needs Ductless Cooling in Tampa?

Ductless cooling is most often used by homeowners with older homes in which adding ductwork may be difficult. Or, if you have a new room addition, you may not have the time or energy to make any more renovations, and ductless cooling is the most efficient way to cool the entire room without extending the ductwork.

Ductless air conditioners have many benefits to homeowners. Ductless mini splits are usually very energy efficient, saving homeowners a lot of money on cooling costs over less efficient options like window air conditioners. Furthermore, a ductless cooling system gives homeowners the benefit of zone control. If one person wants to keep the temperature higher in a particular area, or zone, they can turn the temperature up in that area only, so the rest of the house can stay cooler. Another benefit of ductless cooling is the fact that ductless air conditioners provide both heating and cooling.

Ductless cooling is great for many homes, but it may not be for everyone.

You should talk to a professional technician to decide whether installing ductless cooling in your Tampa home is the right choice. Call the experts at Ierna’s Heating & Cooling today!

What Are HEPA Filters and Do I Need One?

August 18th, 2014 by Charlene Ierna

High indoor air quality is an important part of your overall comfort. There are a number of air cleaners available for whole-home use, and sometimes it can be a bit overwhelming when trying to determine which one is the best fit for you. Today we are going to highlight HEPA filters, but remember that for all your air filtration needs, you want to call on the professionals who can help you: Ierna’s Heating and Cooling.

What Does HEPA Stand For?

HEPA stands for high efficiency particulate air.

How Efficient Is a HEPA filter?

A true HEPA filter is 99.97% efficient. HEPA filters can screen out particles as small as 0.3 microns, which are the hardest microns to trap. Interestingly, this size micron is perfect for entrance into the human body, which is why the size is important. To give perspective on this size, a human hair ranges anywhere from 70-100 microns. HEPA filters capture allergens, dust, dirt and some bacteria and viruses.

What Is the Construction of a HEPA Filter?

A HEPA filter will come in a square frame, and the filter medium will be pleated. The material used for the filter is a paper-like, glass-fiber filter material, and pleats are in a “V” configuration with corrugated aluminum separators between the pleats; pleating helps to trap airborne particles more successfully.

What Are the Benefits of HEPA Filters?

The main benefit of installing a whole-home HEPA filter is increased indoor air quality, particularly for allergy sufferers. Additionally, by capturing some bacteria and viruses, HEPA filters can also increase your overall health. Due to their tight weave and pleated formation, HEPA filters capture a great deal more dust and dirt than a standard air conditioner air filter, which can benefit your AC.

Items to Note

Certain HEPA filters can restrict air flow, so it’s important to work with a professional to understand which HEPA filter is best for your system. In addition, HEPA filters need to be changed approximately every 3 months in order to be effective.

HEPA filters can be great air filtration systems for your home in Lutz. However, as noted above, it may take some work to determine which HEPA will work best for you and your air conditioner.

If you are interested in what a HEPA filter can do for the overall air quality in your home, call the experts at Ierna’s Heating & Cooling today.
