What’s Involved in Custom Duct Design

July 21st, 2014 by Charlene Ierna

Homes that use forced-air heating and air conditioning have ductwork built into them as part of their construction. But there are times when you will need to have new ductwork designed, such as when you have a major upgrade for your whole HVAC system that requires redoing the ventilation system to accommodate it. New ductwork is often necessary for extensive home remodeling jobs. And if you plan to build your own home, then new ductwork creation will be one of the major tasks of construction. (However, you do have the option during renovation and new construction to have a ductless heating and cooling system installed.)

For custom duct design in a Tampa, FL home, you can rely on the team at Ierna’s Heating & Cooling. We have EPA- and NATE-certified technicians to handle the job so that you end up with the custom ventilation system that will make sure your home “breathes” its best.

How custom duct design works

When approaching custom ductwork, the designers will first take into account the heating and cooling system in your home. If you are installing a new air conditioner or heater, try to hire the same company for the custom design of the ducts and the new comfort system installation so that the two work together.

The duct designers will then work out which materials they will use for the ducts. Most ductwork comes in three different materials: sheet metal, flexible plastic, and ductboard. For most homes, flexible ducts will take up the majority of the ventilation system, but sheet metal often forms a trunk line, and the lightweight and inexpensive nature of ductboard frequently makes for a convenient alternative.

Insulation is a key part of designing new ducts: the technicians will determine where in the house the ductwork will most likely lose the largest amount of energy, and they will supply additional insulation for those sections.

Although you can opt for pre-fabricated ductwork for a home, it is far less efficient than the custom fabrication that ductwork professionals can offer. The combination of specially-selected materials, customized insulation, and a design fit to the needs of your home and your HVAC system will mean increased comfort and a significant reduction in the energy loss from the ventilation system.

We have the certifications and experience with ventilation and comfort systems to ensure you top-quality work.

How Does Mobile Home Air Conditioning Work

July 14th, 2014 by Charlene Ierna

Your mobile home may be a bit smaller than some other houses, but this doesn’t mean your air conditioning options are limited. Surprisingly enough, there are several options available to you for mobile home air conditioning installation in Wesley Chapel.

While some mobile home owners may believe window air conditioners are a good choice, this is often not the case. Window units can be noisy and inefficient, requiring several units to match the cooling capacity of one of the indoor air handlers of a central or ductless system. Professional installation of one of the following options may be a better idea for your new mobile home air conditioning system.

Central Air Conditioning

Central split-system air conditioning is a popular choice for residential installation. These systems use an indoor evaporator unit to absorb the heat in your home and a separate outdoor unit to release the heat outside. This type of system is usually fairly cost efficient, but it requires your home to have an existing indoor furnace, with which many mobile homes are already equipped.

Packaged Air Conditioning

If your home does not have an indoor furnace, one of the most popular means of mobile home air conditioning installation is packaged air conditioning. Packaged air conditioners combine all of the components of a split system into one outside unit. This unit is placed outside of your home so that a separate indoor unit is not necessary. Packaged units are often a great solution for the limited space available for AC installation in manufactured homes.

Ductless Air Conditioning

Ductless mini split air conditioning is a great solution for mobile homes without any existing ductwork installed. As with central air conditioning systems, mini splits require an outdoor unit and one or more indoor air handlers. However, unlike central air conditioning, these systems do not need to use any ducts. Instead, air handlers are installed in different areas of your mobile home, and these freestanding units can often be controlled via individual thermostats.

3 Reasons to Replace Your Thermostat

July 11th, 2014 by Charlene Ierna

It’s small but powerful. It controls your entire air conditioning system with a simple click. And when it’s off, your whole system is off.

Yes, we are talking about your thermostat, and sometimes, it can be the one thing that is making your entire system malfunction. If you’ve had our Ierna’s Heating & Cooling technicians visit your home more than once to fix the thermostat, and are continuing to have problems with it, it may be time for a thermostat replacement for your Tampa air conditioning system.

Reasons to Replace Your Thermostat

As we mentioned above, frequent repairs to your thermostat can be an indication that it’s time to consider replacing it. Here are a few other reasons you may want to replace your current thermostat:

  • Better energy efficiency – if your thermostat has some age to it, or isn’t programmable, you may be losing out on some significant energy savings. Older thermostats may not be as accurate as they once were, leading to temperature readings being incorrect. Programmable thermostats give you a level of control over your cooling that you simply can’t get with a non-programmable one, allowing for less cooling during the quiet times in your home and more when busy and occupied.
  • Better comfort – new thermostats not only allow you to manage the timing and temperature of your cooling: you can also measure and program humidity levels and control whole-home air filters and purifiers. Being able to control your entire cooling system from your thermostat means you can tailor your indoor conditions to exactly what you want and need.
  • You are using an old thermostat – it may still work, but if your home’s thermostat is more than 10 years old, you are missing out on the better efficiency, comfort and ease of use you can get with a new thermostat.

Lots of Options, Lots of Help

At Ierna’s Heating & Cooling, we take pride in staying on top of the latest cooling innovations, including thermostat technology. We have everything from classic metal thermostats to the latest Nest and Lutz thermostat options.

If you think it may be time for a thermostat replacement in your Tampa property, call Ierna’s Heating & Cooling and schedule an appointment with one of our thermostat experts.

How Technicians Do Zone Control Installation

July 4th, 2014 by Charlene Ierna

Zone control is one of the most useful additions you can install in your home. If you’ve ever wanted to vary the temperature in different areas of your house, zone control may be a great upgrade for your comfort and for your energy bills.

Zone control is installed in the ductwork and allows you to adjust the temperature in different rooms of the house to your specific preferences. This helps keep your family members happy; if you disagree about the temperature throughout the house, you can always change the temperature to your own specifications in a separate area, or zone.

Zone control can also help you to save money. If you have a large home, you may waste money every month cooling an entire home when only one or two rooms are really in use. With zone control, you can reduce your energy bills by choosing which rooms get cooled and which do not. If your entire family is watching television downstairs, for example, you may decide to turn off the AC upstairs and only cool the living room.

So How Do Technicians Install Zone Control?

Zone control can be installed either with your existing system or with new air conditioning installation. To install a zone control system, a technician must be able to access your ducts. The technician will install dampers within the ductwork in each area or zone you want controlled. A damper is a device that stops or reduces airflow by blocking the ducts that lead to that particular zone whenever the damper is controlled by a thermostat.

The technician will also install separate thermostats in each room or zone. Sometimes, a master thermostat controls every zone as well. When you set the temperature in a room, the dampers open or close to adjust the airflow so the room can reach your desired temperature.

If you are considering zone control system installation in Trinity, contact Ierna’s Heating & Cooling. Our experts can install zone control in your new or existing system so that you and your family can be comfortable, and so that you can save money on your energy bill. Call us today!

3 Factors to Consider Before Ductless Mini Split Installation

June 27th, 2014 by Charlene Ierna

Around this time of year, you may be considering some new options for your AC system. Though you may be more familiar with central air conditioning, it’s not the only option if you’re looking into a new AC system. Today, instead of central air conditioning, many homeowners choose ductless mini splits because of their flexible design options, size, and energy savings. Whether the size or layout of your home makes ductwork installation impossible or you are searching for more control over the placement of your indoor units, a ductless mini split system may be the right option for you.

If you are considering a ductless system in your home, Ierna’s Heating & Cooling offers ductless mini split installation in Wesley Chapel. Here are three factors to consider before a ductless mini split installation:

  1. Ductless Systems Use Multiple Indoor Units Instead of Ducts: As the name suggests, mini splits do not use ductwork for cooling. As with central air conditioning, there is both an indoor and outdoor component. The advantage of mini splits is that multiple indoor units can be installed in your home that are all controlled by an outdoor compressor/condenser unit. Because of this, different rooms or zones can be set with separate thermostats for each one. This can increase your comfort and can help lower your energy bills.
  2. Less Energy is Lost with a Ductless System: A lot of energy is lost within a home’s ductwork because of leaks and holes in the ducts or because the ducts are designed inefficiently. A ductless system can lower your bills by eliminating this potential energy loss.
  3. Ductless Systems Provide Flexible Installation Options: The indoor component of a mini-split system can be installed in various locations throughout your home. This unit can be mounted on the wall or the ceiling and, because they are compact, they don’t interfere with the interior design of your home. A technician will discuss your options with you before the installation of your new ductless system.

Our staff at Ierna’s Heating & Cooling will gladly answer your questions about ductless mini split installation in Wesley Chapel. Call now!

How Do Modular Commercial HVAC Systems Benefit Me?

June 20th, 2014 by Charlene Ierna

One of the major differences between residential HVAC systems and commercial ones is that commercial systems are modular. One of the reasons for this is that it makes the systems easier to manufacture and transport; commercial HVAC systems must be large to supply most spaces with significant cooling and heating—even light commercial—and trying to build a single unit big enough would be too unwieldy.

However, modular systems are also a benefit to you as a business owner for a number of reasons that we’ll look at. For top quality work on light commercial air conditioning in Tampa, FL, whether it’s for installation, repair, or maintenance, call the experts at Ierna’s Heating & Cooling. We also install high-performance commercial HVAC systems to help you lower your company’s heating and cooling budget for the coming year.

Why modular HVAC is good for your company

It’s the nature of businesses to expand if they are successful. Your company can go from a few rooms and a handful of employees to double the space and maybe three times the staff (and customers) in only a year… and it can be exponential over a decade. All of this can happen in the same workspace. In a home, a single air conditioner and heater will match a family until it grows too large so that it must move to a new home. For a business, you need to find a way to expand the cooling and heating without needing to relocate.

This is where the modular system is immensely helpful: you can increase the heating and cooling load of your HVAC systems by adding more packaged units onto the system. This isn’t something of which residential systems are capable. The add-on modules for commercial HVAC come in a range of sizes: 5-tons, 10-tons, 15-tons, 25-tons, up to 50-tons. There is a module size to fit your company’s expansion and comfort needs; you never need to worry about having to tear out the whole system to replace it with a larger one.

This also benefits you when the system begins to age. You don’t have to replace the entire HVAC system when it’s time to upgrade it; you can instead upgrade individual modules as needed, and only need minor disruptions to your work’s schedule. When it comes to repairs, you will also only need to worry about one module at a time going off-line.

Call us for light commercial work

You can trust your business’ comfort to our capable hands.

Ierna’s Heating & Cooling is EPA-certified with NATE-certified technicians on staff to make sure that your company receives excellent work for its commercial air conditioning in Tampa, FL.

Why Do I Need a Whole-House Dehumidifier?

June 13th, 2014 by Charlene Ierna

We’re hitting the 90s already, and we know that in Wesley Chapel we don’t hit the 90s without the humidity coming with it! Humidity makes the air feel so much warmer than it is, and when you’re already at, or over, the 90 degree mark, that extra, moist heat can feel unbearable, both inside and out. Humidity makes our air conditioners work that much harder to achieve the coolness we want in our homes; one great way to help both you and your air conditioner during our hot, humid summers is to install a whole-house dehumidifier in your Wesley Chapel home.

Benefits of Whole-House Dehumidifiers

Since 1904, Ierna’s Heating & Cooling has been helping Florida residents in the greater Tampa Bay area achieve the comfort they want inside their homes, and as a result, we’ve seen first-hand how adding a whole-home dehumidifier helps. Here are a few benefits you can gain when you add a whole-house dehumidifier to your home:

Decrease Allergic Reactions to Dust

Dust mites thrive in moist settings; by removing extra moisture that may be contributing to their growth, you can help reduce the amount of dust allergens in your property.

Prevent Mold Growth

Mold, another serious allergen, grows in shaded, moist areas. Mold growth can damage property and cause serious reactions for those allergic to it. As with dust mites, removing the extra humidity from your home discourages mold growth, making it healthier.

Better Energy Efficiency

Your AC can do its job more effectively with a whole-home dehumidifier. Why? Humidity holds heat; by removing the excess humidity, you help to remove heat that your air conditioner would otherwise be battling. When your air conditioner isn’t using more power to accommodate for the excess moisture in the air, it uses less energy, which can result in lower energy bills for you.

Better Comfort

Humidity clings to the skin, making the air feel sticky and uncomfortable. By removing the extra humidity in your home, you can experience a greater comfort level without having to lower the temperature on your thermostat.

Your Wesley Chapel dehumidifier can help provide comfort, energy savings and better health for allergy sufferers.

What Do UV Germicidal Lights Do for My Indoor Air Quality?

June 6th, 2014 by Charlene Ierna

Indoor air quality is a major household concern today, and in Florida we face an even more difficult obstacle when protecting our air from unhealthy contaminants: the growth of mold, fungus, and other bacteria within our home’s ventilation systems. The humid climate provides an easy medium for these biological pollutants to begin to take hold and grow. Some molds send toxic spores into the air that can lead to serious ailments for people in a house.

Dealing with biological pollutants is tricky, since they often do not go away through traditional cleaning methods. But there is help: UV germicidal lights, a technology used in medicine and laboratories to sterilize environments.

Thanks to companies like Ierna’s Heating & Cooling, you can have UV germicidal lights installed to defend your home against these dangerous intruders. Call us today for an appointment.

The action of UV germicidal lights

In 1903, Icelander Niels Finsen won the Nobel Prize for medicine for his pioneering work using ultraviolet radiation to treat diseases such as tuberculosis. The use of UV lamps spread through the health care world, and today this method of sterilization is widely used for hospitals, laboratories, water treatment plants, and in the food service industry as a way to cleanse bacteria without leaving residual harmful chemicals.

UV lights in your home are positioned within the ductwork, targeted at infested areas and places where bacteria might pass along toward the vents. The extreme short wavelength of the ultraviolet radiation disrupts the cellular structure of molds and microbacteria, stripping away their nucleus and not only killing the bacteria, but also preventing its reproduction. When you use UV lights on your ducts, you’re not only eliminating mold, you’re preventing it from coming back.

Concentrated doses of UV radiation can be harmful to humans (that’s why you should always wear UV shielded sunglasses when outside), but the lamps used to clean ducts are designed for safety and pose no threat to you or anyone else in your household. The lights will carry out their job without you even noticing them.

You will need professionals to install these UV lamps, however, to make sure they are working as they should. It is also wise to have them routinely maintained and inspected, with necessary bulb changes and adjustments.

Ierna’s Heating & Cooling offers a variety of ways to improve your indoor air quality, including professional installation of UV germicidal lights in Tampa, FL that will take care of any mold growth inside your ventilation system. Call us today to learn about what we offer in the way of air filtration and air cleaners as well.

How do Zone Air Conditioning Systems Work?

May 30th, 2014 by Charlene Ierna

Traditional air conditioning systems usually provide a single set temperature for the entire house. You set your thermostat to a given temperature, which will be the same in the bedroom as it is in the kitchen. But that doesn’t always work for every household. For instance, what if you’re working over a hot stove in the kitchen while your spouse wants to read or watch television in the (much cooler) bedroom? That’s where zone air conditioning comes it. It allows you to set different temperatures in different parts of the house, or even turn off the air conditioning in parts of the house you aren’t using. Zone air conditioning in Tampa makes a lot of sense, especially in larger houses, but how do zone air conditioning systems work?

Intro to Zone Air Conditioning Systems

If you have a centralized system, with a series of ducts extending from a single larger air conditioner, then the zone system entails a series of valves and shutters placed inside the ducts themselves. They divide your house into separate zones, usually separated by room, but sometimes by more generalized areas of the household. The valves are controlled by specific thermostats, allowing you to adjust the temperature in each section as you wish. These kinds of systems are usually applied as “upgrades” to existing centralized systems.

The other type of zone control system is also known as a ductless mini-split system. This occurs in homes without a centralized air conditioner. A series of individual air conditioning units is placed within each section, designed to carry a much smaller power load than a centralized system. They function the same way as the valves described above do, and are usually installed in homes which lack the capacity to support a system of ducts.

We handle zone air conditioning, Tampa is our base of operations and we won’t rest until you have all the answers you need. Give us a call today and let us show you what we can do!

Proper Preparation Pays When Replacing Your Air Conditioner

May 23rd, 2014 by Charlene Ierna

With proper maintenance, your air conditioner should last a long time, but sooner or later you’re going to need to get it replaced. When you do, it doesn’t pay to go about it without planning it all in advance. Here in Tampa, air conditioning replacement services can provide you with solid advice on what’s best for your particular circumstances, and you should heed their advice whenever possible. Proper preparation pays when replacing your air conditioner. Here’s a brief overview on the reasons why.

Why Preparation is Key in Air Conditioning Replacement

In the first place, you want an air conditioner that is more efficient than your old one if at all possible. Air conditioning efficiency is rated by SEER (Seasonal Energy Efficiency Ratio) ratings. The higher the rating, the more efficient the air conditioner. You can use a cheat sheet by purchasing a system with the EnergyStar sticker (denoting units with the highest possible rating), but improved efficiency is one of the biggest reasons to replace your air conditioner, so make sure you don’t ignore it.

Once that’s complete, focus on the cooling power of your air conditioner. This is trickier than it sounds. Obviously, if you have a unit that isn’t powerful enough for the size of your home, then it’s not going to cool your home efficiently. But if it’s too powerful, then it will engage in “rapid cycling,” or turning on and off too quickly. Air conditioners use much more power when they turn on and off than they do when they’re just running. A unit’s that’s too powerful for the space will end up costing more money in misspent energy than it saves in cooling power. Since the SEER rating can affect proper sizing, you should settle on a rating before you determine the right size.

Here in Tampa, air conditioning replacement is the purview of Ierna’s Heating & Cooling. We can decide on the best system for you, and ensure that the installation itself proceeds without a hitch!

We have the experience to help you find the right AC system , and we know that proper preparation pays when replacing your air conditioner. Call us today for a consultation.
