The Differences between Air Purification and Air Filtration Systems

July 23rd, 2014

Indoor air quality is a big part of your overall indoor comfort; this is why AccuTemp Heating and Air Conditioning offers indoor air quality services to our customers. Two great ways to improve indoor air quality is through the use of air purification and air filtration systems. Each does something different to improve your air quality, so understanding how an air filtration system works in your Clarksville home versus an air purification system can go a long way toward determining what is best for your needs.

 

What Is the Difference?

The main difference between an air purification system and an air filtration system is this: an air filtration system traps and removes particles from your air while an air purification system destroys pollutants.

What Types of Air Filters Are There?

There are several kinds of air filters available, but they are divided into two main types:

  • Mechanical filters
  • Electronic air cleaners

Mechanical filters come in a frame and act as a sieve to the air coming into your home. They strain the air as it passes through, trapping particles in the media of the filter. Mechanical filters can be pleated and/or extended, and should be changed every 3 months.

There are 2 types of electronic air cleaners:

  • Electrostatic precipitators
  • Ion generators

Both types use electrostatic attraction to capture particles, but there is a difference in the way each manages the particles. With an electrostatic precipitator, air is drawn into an ionization chamber where the particles are charged; these particles are then passed over oppositely-charged plates that capture and collect the particles. With an ion generator, particles are also charged, but they are not collected; instead, they will attach themselves to other oppositely-charged particles and then collect on surfaces in your home.

What Is an Air Purifier?

An air purifier destroys biological material. There are several types of air purifiers, but the most commonly-used one is UV germicidal lighting. UV lights utilize the radiation in UV-C rays to destroy the DNA of pollutants, rendering them unable to reproduce or sustain life. UV germicidal lights are good for removing biological pollutants such as:

  • Viruses
  • Bacteria
  • Allergens
  • Mold spores

One item to note is that UV lights do not remove dust or dirt.

Put Them Together for Total Effectiveness

The best way to get the best air quality in your home is to use both of these products in combination with one another. Pairing an air filtration system in your Clarksville home with UV germicidal lights is equal to a one-two punch for indoor air pollutants.

Why Do I Need a Dehumidifier in My Home?

July 14th, 2014

Humidity is the level of water moisture in the air. Extremes—air that is too dry, air that is too damp—can lead to a multitude of issues in a home that affect comfort, energy use, health, and furnishings. However, installation of a humidifier or a dehumidifier from a professional can combat these problems and create the ideal humidity balance inside a home.

AccuTemp Heating and Air Conditioning handles installation of humidifiers and dehumidifiers in The Highlands, KY, as well as other indoor air quality services such as air filters and UV sanitizing lights. Call our skilled team today to talk about your option to achieve comfortable and safe humidity levels in your home.

Why you may need to install a dehumidifier

In this post we’ll concentrate on the dehumidifier, which is often necessary during a hot and damp summer. You will probably already have a good idea of when a dehumidifier is necessary: uncomfortable, sticky air inside your home; water condensation along the windows and walls; and towels that dry slowly.

Here are some of the specific reasons you should have a dehumidifier installed:

  • Comfort: High humidity makes it difficult for the human body to release heat through sweat. This means more trapped heat that makes a hot day feel even hotter. Lowering the humidity in your home will make summer heat waves much more bearable.
  • Energy savings: In connection with feeling more comfortable in the summer weather, you will need to run your air conditioning system much less. Dropping humidity from an unpleasant 80% to a balanced 50% can mean lowering your air conditioning usage by a third… and that’s a difference you will notice on your utility bills.
  • Improved health: High humidity encourages the growth of a number of toxic molds that will damage your indoor air quality and will have severe effects on people with allergies and asthma. It can also lead to respiratory problems in otherwise healthy people.
  • Water damage: Layers of moisture are destructive for many surfaces, especially wood, which can develop wood rot. Mold and mildew will also cause rapid damage to a house.

Have a whole-house dehumidifier professionals installed

The proper way to combat high humidity is with a dedicated whole-house dehumidifier fit into your HVAC system. A standard air conditioner will lower humidity somewhat, but this is not what an AC is designed for and is rarely sufficient to combat high water vapor levels. Call on a professional to find the right size and type of dehumidifier for your home (you don’t want the humidity level to drop too far) and install it.

AccuTemp Heating and Air Conditioning carries a variety of dehumidifiers for The Highlands, KY. Let our indoor air quality team help you find the right one and eliminate your home’s damp air.

What Are the Benefits of Packaged Air Conditioning Units?

July 7th, 2014

If you’re used to seeing home air conditioning systems, you’ve probably become accustomed to split systems—those that rely on both an indoor and outdoor unit to remove heat from your home and release it outdoors. Usually, an indoor unit with an evaporator coil helps to absorb heat in your home and circulate cool air, while a large outdoor unit with a condenser coil and a compressor dissipates the heat into the air.

This type of system is very common for residential use, but there are other options. Packaged air conditioning units are self-contained systems, meaning that the indoor and outdoor components typically separate in most air conditioning systems are located in one unit. For some types of homes and for commercial properties, this can have many benefits.

Ease of Maintenance and Service

One benefit of packaged air conditioning units is that maintenance and service are often easier when an air conditioning technician can access all of the different parts of your system from one location. Most systems separate the evaporator and condenser coil, so a maintenance technician may need to spend a lot of time in your home to inspect and clean all components. With packaged units, a technician can inspect every area of your AC with ease. Similarly, technicians can often locate repair issues more easily when you experience problems with your unit.

Convenience of a Single Unit

Furthermore, a single unit may be more convenient for homeowners and businesses that have special requirements for space and design. Packaged air conditioning can be installed in many ways including wall-mounted, window, and rooftop units. Wall-mounted and rooftop units can remain fairly hidden from view while continuing to function like any other system, using the building’s ductwork to cool one or multiple rooms. For homes without ducts or those without space for an outdoor unit, a window or wall mounted packaged unit can be the perfect solution.

Accutemp Heating and Air Conditioning offers professional installation on packaged air conditioning units in the New Albany area. Call us today!

The Famous Painting of the Declaration of Independence Isn’t What You Think It Is

July 4th, 2014

If you grew up in the United States, you probably first saw John Trumbull’s painting of the Signing of the Declaration of Independence in an elementary schoolbook. This oil-on-canvas 12’ x 18’ painting hangs in the rotunda of the United States Capitol in Washington, D.C. It is one of the most famous symbols of freedom in the country and almost every citizen can conjure it from memory.

Except… the painting isn’t of the singing of the Declaration of Independence. The actual title of the work is Declaration of Independence, and although it does portray an important moment in the history of the document that announced the Thirteen Colonies’ decision to break away from British rule, the event in the painting occurred on June 28, 1776, not July 4, 1776.

John Trumbull, a Connecticut native who fought in the Revolutionary War and whose father was the state governor, was commissioned to create the painting in 1817. He did painstaking research on the figures in the picture and also visited Independence Hall to see the actual chamber where the Second Continental Congress met. Trumbull only included 42 of the original 56 signers, because he could not find adequate likenesses for 14 or them, and added a few figures who were not present (most of whom declined to sign the actual document). In fact, the men depicted in the painting had never been present in the same room at one time.

So if the painting does not portray the singing of the Declaration of Independence, what is happening in the image? The Trumbull’s scene depicts the presentation of the draft of the declaration to the Continental Congress for editing and approval. The five-man drafting committee (John Adams, Roger Sherman, Robert R. Livingston, Thomas Jefferson, and Benjamin Franklin) is handing over their finished work, which congress would then edit carefully over the next few days before voting on it and signing it on the day that we now celebrate as the start of the United States of America.

One last, odd, fact: two of the five-man drafting committee, John Adams and Thomas Jefferson, both died on the July 4—although many years later.

Our family at AccuTemp Heating & Air Conditioning hopes that your Fourth of July (or Twenty-Eighth of June if you decided to start celebrating early) is a memorable and happy one.

Principles of Geothermal Loop Systems

June 27th, 2014

The power to heat and cool your home—affordably, efficiently, and without harming the environment—lies right beneath your feet and all around your house. It’s the power of the Earth itself, which you can harness through geothermal loop systems in Louisville, KY.

A geothermal heat pump uses the ground as a medium for exchange. This separates it from an air-source heat pump, which uses the air as its medium. We’ll explain in this post how the geothermal loops in the ground can bring you heating and cooling that’s more efficient and reliable than what you receive from traditional home comfort systems.

Make a call to AccuTemp Heating and Air Conditioning to find out more about geothermal loop systems and how our skilled installers can make them work for your home.

How geothermal loops work in a ground-source heat pump

The basic principles of a geothermal heat pump are the same as that of a standard heat pump: moving heat from one place to another through the cycling of refrigerant. In heating mode, a heat pump moves heat from outside a home to the inside, and releases the heat through the process of condensation along an indoor coil. In cooling mode, a heat pump moves heat from inside a home, absorbing it along the indoor coil through evaporation, and releases it outside.

The difference between the two systems is the “outside the house” part. For a standard heat pump, an outdoor coil does the job of either releasing or absorbing heat. But with a geothermal system, there’s no outdoor coil. Instead, the refrigerant (which is water or a water/anti-freeze solution) moves into a set of loops buried in the ground at least 10 feet below the frost line. The loops either release heat into the ground or absorb it.

The advantage of using the earth for half of the cycle of heat exchange is the stable temperature found below the frost line. At 10 feet or deeper, the earth stabilizes to 55°F, and does not fluctuate due to weather conditions, whether extreme heat or cold. This gives a geothermal heat pump a reliable source for heat exchange, and it won’t struggle or lose efficiency no matter the outdoor temperature. The U.S. Department of Energy estimates that geothermal heat pumps, thanks to their ground loops, can run 3 to 6 times more efficiently than air-source heat pumps. It requires only one kilowatt-hour of electricity for a geothermal system to produce 12,000 BTUs of cooling or heating power, compared to more than twice that for a standard heat pump during a hot day. The efficiency is even greater in heating mode.

If this sounds like the energy-saving performance level you want from your home comfort system, and if you are interested in green technology with zero greenhouse gas emissions, call AccuTemp Heating and Air Conditioning today. We specialize in the installation of geothermal loop systems in Louisville, KY.

Problems Solved by Duct Sealing

June 20th, 2014

Have you noticed any of the following in your home:

  • Moldy, dusty smells emanating from the vents?
  • A drop in airflow from your air conditioner or heater?
  • Rooms that feel uncommonly warm or cold?
  • An unexplained rise on your utility bills due to your AC or heater?

If so, you may have leaks inside the ductwork connecting your HVAC system to the rooms. This ventilation system must maintain an airtight seal along its length to allow for the conditioned air sent along it to maintain air pressure. Even a small leak can cause a drop of 30% in air pressure. These breaks and leaks in ducts can lead to other problems if they do not receive proper repair work.

You can call for duct sealing in Crestwood, KY from AccuTemp Heating and Air Conditioning. Professionals need to handle the job of closing up the holes and gaps along leaky ducts—store-bought duct tape will not do the job—using a variety of sensors and sealing tools. Our experts will help restore your ducts and solve the following problems:

  • Air pressure loss: This is the main issue that duct sealing addresses. When air pressure drops inside a ventilation system, it means a loss of airflow that will cause a room to receive uneven heating and cooling. You can’t expect your air conditioner or heater to perform its job adequately with leaky ductwork.
  • Elevated utility bills: When air pressure in the ducts drops, it will force the air conditioner or heater to work harder to attempt to compensate for the loss. This will push the system to overwork and drain additional power, and you will see the effects through spikes in your energy bills.
  • Increased repair issues for the heating/cooling system: This stress from overworking will also cause more breakdowns and malfunctions in the air conditioner/heater. Debris and dust will also infiltrate the system cabinets and cause damage that will lead to expensive repair needs.
  • Drop in indoor air quality: The openings along leaky ducts will access closed-in, dusty spaces in your home, and will begin to draw in debris from them. This will cause contamination along the ventilation system that will then blow out into the air of your living spaces. Worst of all, the leaks can cause a rise in humidity that will encourage dangerous mold and mildew growth. Sealing the ducts will protect the health of your family.

If you suspect the integrity of your ductwork has been compromised, call us right away to schedule repairs and sealing work.

Our indoor air quality team and specialists in duct cleaning and duct sealing in Crestwood, KY are ready to help you deal with any troubles you have with your home’s ventilation.

3 Services Performed During Air Conditioning Maintenance

June 13th, 2014

Have you scheduled your air conditioning maintenance in Middletown, KY for the summer yet? It’s never too late to get started, and “now” is always the best time. Maintenance is necessary for your air conditioner to remain at top level of energy efficiency and cooling performance. Maintenance will also spot potential repair issues so you can have them fixed before they turn into mid-season hassles.

Our new customers are often curious to know what happens during a regular maintenance session on an AC. Here are 3 of the key services that the technicians at AccuTemp Heating and Air Conditioning provide during a maintenance visit. Give us a call today to sign up for your maintenance visit before the summer heats up any more.

Here are 3 services you can expect during AC maintenance

  • Electrical system check: Approximately 85% of repairs needed for air conditioners are electrical in nature, so technicians will make a careful investigation of the electrical system in your air conditioner. They will look for loose connections and tighten them, check on the motors and the amperage on the motor connected to the compressor, see that the capacitors are in good shape, and make sure the electrical relays are not damaged.
  • Refrigerant recharge: The refrigerant in your air conditioning system must remain at a set level at all times, or it risks dropping in cooling power and creating ice across the coils. The technician will check to see that the refrigerant in your AC is at the right level. If the charge is low, the technician will add more (making sure it’s the correct blend) so the system won’t run improperly.
  • Change the air filter and check airflow: The air filter protects the interior of an air conditioner from debris pulled in through the return vent. It will become clogged over time and needs to be changed out for a fresh filter. The technician will take care of this and then check on the airflow for the whole system to see if the fan and blower are operating correctly and the ventilation shafts aren’t leaking air.

There are many more tasks that a technician will oversee during the maintenance session: cleaning the coils, clearing the condensate drain, checking the thermostat, etc. At the end of the visit, you will have an AC in top condition and working at its most efficient. (Studies have shown that an air conditioning system that receives regular yearly maintenance will retain 95% of its efficiency during its lifetime.)

3 Ways Commercial Air Conditioning Is Different from Residential

June 6th, 2014

During a Kentucky summer, an effective air conditioning system for your business is essential, whether you run an office or retail location. Cool air from a central AC means comfort for your clients, customers, and employees… and better business for you.

It takes more to handle commercial air conditioning repair than a background in working on home ACs. There are some huge differences between the two. Here are three of the most important ones.

AccuTemp Heating and Air Conditioning has the years of experience with commercial air conditioning repair in Louisville, KY, so make us your first call when you need help restoring your business’ comfort.

1. Commercial air conditioners are modular

Residential air conditioners come as single units capable of handling a set cooling load. If a homeowner wishes to add more cooling power, he or she must replace the current unit with a larger one. Commercial systems are modular, however. This makes them easier to construct and transport, but it also allows a business owner to add onto the system to increase the amount of cooling load without needing to replace the entire system. For businesses that plan to grow, either in space or in staff, modular designs are essential.

2. Commercial air conditioning usually is designed as packaged units

Take a look at the central air conditioning for your home: it has an outdoor unit (the condenser) and an indoor unit (the evaporator). This is known as a “split system.” Commercial systems are different: they place the condenser, the evaporator, and all the other components into a single cabinet called a package unit. These package units can also be heat pumps for both heating and cooling. Package units have the advantage of making them easy to access and repair for technicians. Since most package units are located on the roof of a business, they remove a great deal of noise pollution from the workspace and do consume valuable room.

3. Commercial air conditioners are larger and more powerful

The average cooling load needed for a medium-sized residential home (one story, 3 bedrooms) is about 5 tons. By comparison, 25 tons is considered “light commercial” air conditioning. Many businesses use multiple 50-ton modular units to provide sufficient cooling for their space. Also part of the larger size for these systems is the extensive ductwork and the multiple thermostats necessary for zone control. The extent and size of commercial HVAC systems require that only technicians with special training work on them.

We have a long record of successful work on commercial HVAC systems, and will deliver the same level of quality to your business.

For the necessary air commercial conditioning repair in Louisville, KY that will restore your company’s cool interior, call the dependable team at AccuTemp Heating and Air Conditioning.

Types of Air Filters to Consider for Your Home

May 30th, 2014

Homes in the U.S. face a serious problem today with the quality of their indoor air. Because homes are designed today to maintain a strong seal against the outside heat (and from heat escaping), very little fresh air circulates during most of the year. This leads to air that is stale and filled with household contaminants such as dust, dirt, dander, fibers, and chemicals from building material and cleaners.

There are ways you can combat this in your house, however—and you don’t have to throw open your doors and windows to the elements half the day to do it. (However, it’s still a good idea to let some fresh air in now and then.) With the help of professionals in indoor air quality in Clarksville, IN, you can have special air filters installed that will clean and purify your indoor air.

How to get started? Call up AccuTemp Heating and Air Conditioning today, and we’ll talk over some of these options:

The mechanical filter

A mechanical filter uses a mat of fibers to catch and trap particles. The fibers attract pollutants to them, so even particles down to 0.3 microns will not manage to make it through the filter—this will account for around 99.7% of all the dust and debris that floats through your home. The finest mechanical filters are HEPA filters, and with their help most of the major pollutants that cause asthma and allergies will vanish from your home’s air. The filters will need regular maintenance to keep them clean, however.

The air purifier

Also known as an electronic air filter, these devices can affect the contaminants that will escape a mechanical filter; namely, gases such as smoke, formaldehyde, pesticides, carbon monoxide, etc. The electronic filter ionizes the air and then attracts particles to a plate, thus affecting pollutants down to 0.1 microns in size. They use electricity, but not enough to make a significant impact on your utility bills.

Standalone units

In addition to cleaners that are installed into your HVAC system, you can have standalone air purifiers that are sized for your home. These can be used for a single room, or designed to work for a larger set of rooms, depending on your needs. These units work well if you need to cleanse to air in a room of someone with bad allergies or asthma.

Although you can purchase some indoor air quality appliances from stores, most of them will not do a sufficient job, and they will not benefit your whole household. For this job, hire on indoor air quality experts to select and size and then install the ideal air filtration system for your home.

When you want the finest indoor air quality in Clarksville, IN, call the experienced indoor air quality team at AccuTemp Heating and Air Conditioning.

How Does Zone Air Conditioning Work?

May 23rd, 2014

The standard central air conditioning system that uses a ventilation network to distribute cooled air presents an “all or nothing” dilemma. Regardless of how many rooms in a home needs lower temperatures, all of the house receives the cooling power. If you are only spending time on one section of the house, you don’t need to cool them down. If you have rooms that only guests use, sending air conditioning to them most of the year is a waste of energy. However, there isn’t anything you can about it—

Stop right there. You can change the way you cool your home so that instead of doing it all at once, you instead have the house divided into different “zones,” each with temperature controlled separate from each other. Thanks to zone control systems installed into an HVAC system, you can control all the cooling from a central panel, or adjust the individual zones locally.

To find out how you can have zone air conditioning in Louisville, KY for your house, call the specialists at AccuTemp Heating and Air Conditioning today.

Here’s a rundown on how zone control operates.

The basics of zone control

The standard element of a zone control system is the damper. These valves go into the ductwork, each one controlling the flow to a zone. (You can decide how many zones you need; they can be as simple as one for upstairs and one for downstairs, for as many as one for every room.) The dampers can shut partially or all the way to reduce or stop airflow to a zone, which reduces the strain on the AC as well.

The dampers are each hooked to a local thermostat that allows anyone in the room to control the temperature. This is a great advantage since it means people in your home with personal comfort needs can find the right temperature for them without disturbing the comfort level of others. It also means you can adjust temperatures to fit a room’s purpose: slightly warmer for the baby’s room, cooler for a home gym or the kitchen.

Each of the individual thermostats hook up to a central control panel, located where the standard thermostat is usually placed. The control panel allows access to any of the zones and permits programming that allows the homeowner precise temperature control throughout a house.

Ready for zone control installation?

You don’t have to have zone control installed when you put in a new air conditioning. Professionals can retro-fit an existing installation system and AC to have all the zone control advantages. Speak to our Louisville, KY zone air conditioning technicians today and set up an appointment. AccuTemp Heating and Air Conditioning is glad to help you get the most comfort and savings from your heating and cooling system this year and every year after that.
