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.

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.

 For superior custom ductwork call Ierna’s Heating & Cooling to set up an appointment with our specialists in custom duct design in Tampa, FL.

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!
