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.

Do I Need Air Conditioning Maintenance or Repairs?

August 11th, 2014 by Charlene Ierna

An air conditioning system can last for many years, but in order for it have the longest lifespan possible, it requires two things:

  1. Regular preventive maintenance done annually
  2. Prompt repairs whenever necessary

If an air conditioner’s repair needs are neglected and it is left without routine maintenance visits, it will not last long. Air conditioners that never receive inspections or required repairs will rarely work for more than a couple of years before breaking down and needing a replacement—and they will start to perform inefficiently and waste energy long before that.

To keep up with regular maintenance and repairs, rely on a professional company like Ierna’s Heating & Cooling.

We offer emergency repairs and a plan for regular air conditioning maintenance in Wesley Chapel, FL. Contact us today to set up an appointment for a maintenance visit to get you started.

When you need repairs and when you need maintenance

If your air conditioner is showing any of the following signs, you need to call for repairs right away:

  • An abrupt drop in cooling power
  • Strange noises from the cabinet
  • Ice appearing anywhere on the system
  • “Hard starting” whenever the compressor tries to come on (i.e. stuttering and suddenly shutting down)
  • Acrid smells from the vents
  • A reduction of airflow
  • Uneven heating through the house
  • The system refusing to turn on/refusing to turn off
  • A sudden spike in your utility bills

All of these indicate a serious problem within the AC that will need a repair professional to address. When anything seems seriously wrong with the air conditioner, bring in repair experts.

Maintenance is something you should arrange to have done the same time each year, regardless of the condition of the system. The best time for maintenance is during the spring so you can prepare the AC for the stresses of summer. However, there is never a bad time for maintenance if the system is overdue, especially in Florida where the weather remains hot for much of the year.

You shouldn’t arrange maintenance if something seems actively wrong with an air conditioner; this is the time for a repair call. However, during maintenance, a technician will be able to tell you if there are repairs you should schedule soon.

Sign up for maintenance

If too long has passed since you had a maintenance session from a professional—or if you have never had maintenance at all—then you should call an HVAC company with a maintenance program as soon as possible. It’s never too late to get started, and it will help avoid numerous repair calls in the future.

Ierna’s Heating & Cooling has a program for air conditioning maintenance in Wesley Chapel, FL that will help you get a long service life from your AC. Call us for more details. You can always reach us for emergency same-day service when it’s time for repairs.

3 Common Problems with Ducts

August 4th, 2014 by Charlene Ierna

Because the ductwork that provides air to your home is hidden from view, you may not think about it very much at all. However, ducts are vulnerable to many different repair problems and may account for a good portion of excessive energy costs, limited air supply to your home, or poor air quality. It’s important to maintain ducts by scheduling professional maintenance, duct cleaning, and duct sealing whenever necessary. If you’ve never thought about scheduling ductwork service before, here are three common problems with homeowners’ ductwork in Wesley Chapel.

1. Leaks

The ducts of a typical home may be responsible for a large portion of energy loss due to loose connections or holes. Ductwork is installed in pieces, so it’s not surprising that connections may loosen or break apart over time. However, most homeowners don’t take the proper steps to keep their ducts free of leaks, such as scheduling regular maintenance and calling for duct sealing by an air conditioning specialist. Sealing leaks may significantly increase efficiency and allow for even cooling throughout your home.

2. Dirty Ducts

Indoor air quality is important to many homeowners, but dirty ducts can let a number of pollutants into your home which may exacerbate allergies or irritate sinuses. Professional duct cleaning is an important service you should schedule about once every three years or so, although this number often varies depending on a variety of factors.

3. Faulty Installation

Well-designed ductwork should be built for maximum efficiency and to provide the perfect amount of airflow in and out of your home. Placement and sealing are also important to prevent outside elements and heat from getting into the ducts. Unfortunately, many ducts are designed poorly, and you may notice a loss of conditioned air and higher cooling costs if your ducts are not installed by an experienced HVAC technician. Before duct installation, it’s important to find a quality technician for a custom ductwork design that will provide optimized efficiency and performance.

The ducts are a component of your central air conditioner that deserve a lot more attention than they are given.

When you need installation or maintenance for ductwork in Wesley Chapel, call the trained and certified technicians at Ierna’s Heating & Cooling today!

How to Tell You Need Generator Repair

July 28th, 2014 by Charlene Ierna

Generators pose an interesting challenge when it comes to repairs. With most important appliances for your home, you use them on a regular basis. But with a generator, you hope that you don’t have to use it regularly. In fact, you hope that you don’t have to use it all. Its main purpose most of its lifespan is to provide you with the assurance that should your home encounter a long-term power loss, you will have a backup to keep your essential services working to protect you and your family.

And because the generator rarely needs to work, it can be difficult to tell if it requires repairs. It’s vital to know if there is a malfunction, because you don’t want to find yourself stuck in a power outage with a generator that won’t turn on. But there are some ways to tell that a generator needs preventive repairs. Contact Ierna’s Heating & Cooling whenever you think you need generator repair in Riverview, FL. We can deliver same-day emergency service.

Here’s ways to tell you need generator repairs done

  • Through regular maintenance: The best way to make sure a generator is ready to do its job when the time comes is to have it receive regular maintenance from professionals. In general, you should have maintenance done twice a year, before storm season and soon afterwards. A maintenance technician will run tests of the system to see if there are faulty connections, stale fuel, or fuel supply problems. The check after the storm season will make sure that the unit hasn’t sustained damage. Maintenance will also keep the engine lubricated and handle oil changes, which are essential for a properly operating generator.
  • Running tests on your own: Every few months, turn your generator on for a short time. Make sure that it starts quickly without encountering trouble (starting problems often indicate the fuel supply is going stale and needs re-filling) and is able to provide the power levels you need. Listen for any odd noises from the unit that could indicate wear and tear. If anything seems amiss, call for professionals right away.
  • The unit sustains damage: Make a visual check on the generator occasionally to see that it hasn’t sustained any physical damage from weather conditions or human interference. It’s a good idea to make one of these visual checks (as well as perform a test run) after any major storm—even if you didn’t experience a power outage.

We cannot emphasize enough the importance of regular generator maintenance. It is easy to let a generator slip from your thoughts during a long period of serene weather, but storms and power outages can strike suddenly, and you don’t want to discover you require repair work right when you need the generator the most.

Call up Ierna’s Heating & Cooling to arrange for maintenance today so you can have any necessary generator repair in Riverview, FL done in time for storm season.

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.

Ierna’s Heating & Cooling offers top-of-the-line air conditioning installation for your mobile home in Wesley Chapel. To learn more about mobile home air conditioning installation, call us today!

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.
