Which Type of Filter Works Best for Air Filtration?

October 13th, 2014

Many homeowners keep their windows and doors closed throughout the day and night as they run their air conditioning and heating systems to achieve a desired temperature and humidity level. Unfortunately, this means that you are circulating the same stale, polluted air over and over, a cycle which could lead to irritation or worsen health problems in individuals with allergies, asthma, and other respiratory issues.

Yes, your HVAC system has a removable filter intended to keep some pollutants out of the air. But is this enough to provide fresh, clean air year round? Take a look at some of your other options below.

  • Mechanical Filter: A mechanical air filter is a filter that works with your HVAC system, using fibers to strain particles that are larger than 0.3 microns in size. Don’t just stick with your old model when replacing your filter every month; a HEPA filter is most effective at removing allergens, ridding your home of 99.7% of dust and pollutants. However, some gaseous pollutants may still pass through.
  • Standalone Units: Standalone air purifiers may be used even when your HVAC system is not in use. These can rid your home of mold spores, dust, dust mite feces, pollen, and pet dander, all of which can lead to respiratory issues.
  • Whole-House Air Purifiers: But perhaps the most effective solution is a whole-house air purification system that works with your HVAC unit. These systems use ionization or an electrostatic charge to catch most allergens and gaseous pollutants, including smoke, pesticides, carbon monoxide, and the residue from paint or some cleaning products.

Which Type of Filtration is Right for Me?

Whole-house air purification systems are the best way to target pollutants in all locations of the home and keep allergens from spreading. You may decide that this is the best way to ensure the air that blows into your home is pure, but a specialist should help you choose whether you need an electrostatic precipitator or an ion generator.

For the best filtration possible in your home, remember to change or clean your air filter every month.

What Makes Geothermal One of the Most Efficient Heating Systems?

October 6th, 2014

Geothermal heating operates on the same principal as an air heat pump, moving heat from one place to another to increase energy efficiency. It does this by siphoning heat from underground to heat the house. Let’s start by taking a look at what makes up a geothermal heat pump.

Geothermal Parts

The main part of a geothermal unit is the pump itself. This pump is usually located in a basement or a garage, similar to any other heating system. The pump possesses both heating and cooling capabilities. It uses these to adjust the temperature of the subterranean thermal energy it collects before circulating it throughout the house using a duct system. Mechanically, the unit itself operates much the same way as any other heat pump. What makes a geothermal heat pump truly unique is its source of thermal energy.

Geothermal Installation

A geothermal system begins by digging a trench approximately ten feet down. This is the depth at which underground temperature is more or less constant. Trenches are usually dug in large rectangles, but if space is limited they can be dug vertically. Tubes are then installed in the trench. These tubes can carry either air or water as the medium for absorbing thermal energy. Then, the tubes are connected to the central unit and the trench is filled in.

Energy Efficiency

What makes geothermal heating one of the most efficient heating systems is the consistent, renewable subterranean thermal energy it utilizes. Once you get around ten feet underground, the temperature remains close to 54 degrees, regardless of season or weather conditions. When an air-based system attempts to heat a house, it has to pit itself against whatever the air temperature is currently. This could easily get into the single digits, depending on where you live. The colder the temperature, the longer it will take for the heating system to reach the target temperature. When a geothermal system heats a house, it only needs to heat the air from 54 degrees. This spares the geothermal unit from having to work as hard as other systems, making it more efficient.

Heating Repair Question: Why Does My Furnace Run Constantly?

September 29th, 2014

When it’s freezing outside there is no better feeling than basking in the warmth of your heating system. It can get a bit disconcerting, however, when your furnace seems to work too hard or never turn off. This can cause your heating bill to go up unnecessarily and shorten the life of your furnace. If your furnace seems to be working harder than normal, read on to discover what might be the cause.

Thermostat Issues

The most common issue with furnaces running too often is the thermostat. Before you consider any more involved heating repair, check your thermostat display. Is the temperature set too high? Is the thermostat set to “fan”? If the display seems accurate but the furnace isn’t shutting off, it might be a problem with the thermostat rather than the furnace. Most modern thermostats are far more complicated than the older. It is therefore recommended that you have a professional determine the problem, rather than trying to fix it yourself.

Poor Insulation

Much of the heat loss from homes is due to small cracks in window and door frames. If your home is poorly insulated, you’ll lose heat faster and your furnace will have to work much harder to maintain temperature. This is difficult to diagnose on your own, as poor insulation often has multiple small factors spread around the house. If all your doors and windows are closed and your home still feels drafty, call a professional to examine your home for possible insulation issues.

Wrong Unit Size

If your furnace is a new installation, it is possible that the unit is too big or too small for your home. This can lead to the furnace to overwork itself while trying to match the capacity of a differently sized unit. If everything else seems to be fine but the furnace is still running too often, call a professional to evaluate whether your unit is the right fit for your home.

If you are having problems with your furnace, call AccuTemp Heating and Air Conditioning. Our heating repair experts operate throughout Jefferson County.

Noises That May Indicate the Need for Furnace Repair

September 22nd, 2014

Strange noises are one of the main ways your furnace lets you know that something isn’t going well with its operation. There are noises that are part of normal operation, but there are other noises that aren’t, and they are a signal to you that it’s time to call AccuTemp Heating and Air Conditioning for furnace repair in Louisville. Following is a list of some common noises your furnace can make when it may be in need of repair.

  • Clanging – if you have a hydronic heating system (one that uses a boiler to heat water), the heat is delivered via a system of pipes. Banging or clanging sounds can be an indication that there is a problem with the pipes. Piping for your heating system can be complex, so it’s best to call a professional should you hear these kinds of noises.
  • Rumbling – the burners in your system will get dirty with normal use; a rumbling sound can indicate that there is too much dirt in the burner, and it may be hampering the operation of the burner. Rumbling can also indicate that the pilot light may need to be adjusted.
  • Constant clicking sound – this is a scenario that is more likely to occur with a gas furnace. If you’ve ever owned a gas stove, you know that the burners make a clicking sound until they light; but if the pilot light is out, they won’t light. Your gas furnace can make this same clicking sound when there is a leaky gas valve or loose wiring.
  • Screeching – screeching is indicative of problems with a belt, ball bearing or possibly the motor. These types of repairs are usually not dangerous, but should be taken care of as soon as possible as they can lead to larger problems.
  • Booming – there is usually a whoosh sound when your furnace starts-up, but a booming sound can be indicative of a buildup of gas from a delay in ignition, and can be potentially dangerous. If you hear a booming sound, call your technician immediately.

Strange sounds are one of the ways your heating system communicates that a problem has developed – don’t ignore it.

Choosing the Right Air Conditioning System for Your Home

September 15th, 2014

Choosing to replace your air conditioner gives you the opportunity to find an energy-efficient system that provides excellent performance and the best bang for your buck. But how do you figure out whether an air conditioning system is right for you? While you can do plenty of research, it’s best to talk to an AC technician to ensure that you have the right type for you home and that you aren’t paying too much every month on your energy bills. But the following tips can give you an idea of what to look for when you need air conditioning replacement.

Choosing a Type of System

If you’ve been considering air conditioning replacement for a while, you may have searched around and discovered that there are many different types of systems available. The most common type are central air conditioners, which require installation of both an indoor and outdoor unit. In a packaged system, on the other hand, all of the parts are enclosed in a single cabinet, and you can often install it out of view on the rooftop. In general, if you already use traditional central AC, it may be best to choose a similar system. But if space is a concern for you, talk to an expert about packed units. Finally, a ductless mini split is a split-system AC that doesn’t require any ductwork at all, which is perfect for new room additions in which duct installation may be a hassle.

Energy Efficiency

You should also search for an efficient system that may save you money over time. All air conditioners sold in the U.S. are required by law to include pertinent information about the efficiency of the unit. Efficiency is measured by the SEER (Seasonal Energy Efficiency Ratio), and a higher number indicates greater energy savings. The ENERGY STAR label is another way to tell that your unit meets the Environmental Protection Agency’s high standards of performance and efficiency.

The Right Installer

If your system is sized or installed incorrectly, however, the SEER and ENERGY STAR may no longer guarantee an efficient unit. Air conditioners that are not installed properly or are not the correct size for your home cannot run efficiently and are likely to fail prematurely.

How Can Thermostat Replacement Save Money?

September 8th, 2014

When your air conditioner doesn’t work correctly, it’s easy to think that something big has gone wrong. Sometimes, though, it can be something small, like your thermostat. Your thermostat is the instrument that tells your air conditioner when to cycle on and off, and if it malfunctions, it can cause a variety of problems. Thermostats can break and age just as any other piece of equipment, so if you are seeing a lot of issues with yours, it may be time to consider thermostat replacement in your New Albany home.

AccuTemp Heating and Air Conditioning has a lot of thermostat options, and our trained experts can help you install and maintain it – just call give us a call.

Types of Thermostats

There are three main types of thermostat from which to choose:

  • Digital – digital models are very precise, which helps to improve efficiency when heating and cooling your home. Their faces are easy to read and their buttons are straightforward and intuitive to use.
  • Programmable – programmable models can be programmed in loops of 7 days, allowing you to set cooling or heating as needed. With a programmable thermostat, you can plan for times of low-to-no occupancy in your home, weekends and even vacation time. There is no running back and forth with a programmable thermostat, allowing you to reduce energy consumption.
  • Smart (wireless) – smart models have the benefit of being digital and programmable, but take things a step further by giving homeowners the ability to remotely access and manage their thermostat. By downloading a simple app to any smart device (phone, computer, tablet), you can program your thermostat and even track your energy usage.

How Does a Thermostat Replacement Save Money?

There are a couple of ways a new thermostat can save you money:

  • Energy efficiency – as we mentioned above, a new thermostat offers precision, which helps save energy. If you upgrade to a programmable or smart thermostat, you can take your energy efficiency a step further with planning and management.
  • Less wear and tear on your system – precision and programmability can reduce the amount of time your system operates, which can reduce the amount of wear and tear it suffers.

A new thermostat can help you improve your energy efficiency and comfort level without a huge effort. Call AccuTemp Heating and Air Conditioning today and schedule an appointment with one of our installation experts.

The Fashion of Wearing White and Labor Day

September 1st, 2014

You may have heard about the fashion faux pas of wearing white after Labor Day. In the present, this tradition is usually treated as old fashioned and a joke. Few people will criticize you for wearing white articles of clothing after the first Monday in September, or even take notice of it except to wonder why it was ever a major concern at all.

Where did this tradition of white clothing going out of fashion after Labor Day come from, and why did it fade away like colorful fabric washed in a hot load in the washing machine?

In general, white makes sense for the heat of summer. Light-colored clothing reflects away the radiant heat of the sun, instead of absorbing it the way dark colors do, so for thousands of years of human history people have preferred to wear white clothing during the hotter months.

However, the idea of white as strictly fashionable during the summer season only emerged in the nineteenth and early twentieth centuries—the time when the very concept of “fashion” began to spread across the Western Hemisphere.

It was only the highest level of post-Civil War society in the U.S. that strict and often bizarre rules for fashion controlled whether someone was in with the “in” crowd. Compared to our ideas of what’s fashionable today, the Czars of Style in the 1880s were true despots. Things as trivial as sleeve length could determine whether a woman in high society—no matter her level of wealth—was fashionable or a pariah.

Wearing white during the only summer, when it was common for weddings and outdoor parties, was only of these restrictive society rules. When the U.S. government made Labor Day a federal holiday in 1894, the Fashion Czars gained a definite cut-off point for when wearing white was no longer “acceptable” in the upper echelons of wealthy society.

For many decades, this rule only applied to a small number of millionaire socialites in a few big cities, but in the 1950s it reached general fashion magazines that were read around the country and started to affect more people.

But time eventually broke apart this odd rule, and during the 1970s fashion became more individual. Some fashion legends, like Coco Chanel, also purposely rejected the restriction and wore white throughout the year. Today, the “no white after Labor Day rule” is little more than an amusing gag to tease friends, and almost nobody takes it seriously.

Whatever you choose to wear after Labor Day (and if it’s white, we won’t tease!), everyone here at AccuTemp Heating and Air Conditioning hopes you have a happy end of the summer and great plans for the fall!

Duct Repair Increases Energy Efficiency: Here’s How

August 27th, 2014

Today’s air conditioners are very energy efficient – but that efficiency can disappear if your air ducts are faulty. These can easily be forgotten because it isn’t visible like the other parts of your air conditioner, but it can and will wear down over time. Duct tape won’t repair it, so if you truly want to have your ducts in St. Matthews repaired, call the experts who can help: AccuTemp Heating and Air Conditioning.

Signs It’s Time to Fix Your Ductwork

Here are some common signs that it’s time to repair your ducts in St. Matthews:

  • Constant whistling noises in your vents – whistling noises usually indicate air escaping as it passes through the duct.
  • Odors – unpleasant odors can indicate growths in your ducts such as mold or mildew, or that an odor is being pulled into your air duct through leaks.
  • Loud banging sounds at start-up – loud banging noises can indicate that sections may be collapsed.
  • Loss of air – faulty ductwork can be responsible for up to 30% of total air loss in your home, which can be evident from high monthly energy bills.
  • Uneven cooling – distinct hot and cold spots throughout your home can indicate that some vents are working better than others, or that significant amounts of air are leaking from certain vents.
  • Visible holes and cracks – any openings result in air loss for your system.
  • Excess humidity – not only does air escape when issues are present, but the outside air can get in. If you notice a higher level of humidity in your indoor air, it could be extra moisture coming in through leaky vents.

Increase Energy Efficiency with Duct Repair

All of the above situations contribute to reduced energy efficiency. Why? Your air conditioner has to compensate for the loss of air, and it does this by working harder. Any time your AC has to work harder, it needs more electricity to do so.

If you are seeing the signs of faulty ductwork, call the company that can help you professionally repair your ducts in St. Matthews: AccuTemp Heating and Air Conditioning.

How UV Germicidal Lights Help Protect Your Indoor Air Quality

August 20th, 2014

Mechanical air filters are great for indoor air quality, but capturing certain kinds of biological contaminants with air filters alone can be challenging. This is because many bacteria and viruses are very small, and can slip through the filter media. Additionally, even if they are captured in a filter, they are not eradicated. To truly remove biological contaminants from your home, you may want to consider an option like UV germicidal lights for your Jeffersontown property. UV germicidal lights can be easily added to your current air conditioning system by trained professionals from Accutemp Heating and Air Conditioning.

What Do UV Germicidal Lights Do?

UV germicidal lights emit radiation from UV-C rays. These types of rays kill the DNA of cells and destroy the life-sustaining proteins the cells need to reproduce and survive. So not only do UV lights kill existing biological contaminants; they also destroy any ability for them to reproduce, thereby eradicating them from your air conditioning system. UV lights are over 99% effective in destroying contaminants.

Where Are UV Lights Placed?

UV lights can be easily placed in a variety of spots, but two of the best places are the evaporator coils and ductwork. This is because growths like mold, mildew, algae and fungi thrive in cool, moist, dark places.

What Are the Other Benefits of UV Lighting?

Aside from destroying biological contaminants, UV lights also:

  • Eliminate odors
  • Destroy volatile organic compounds (VOCs)
  • Create negative hydroxyl ions

Do UV Lights Filter the Air?

UV germicidal lights do not filter pollutants out of the air, so they are often paired with an air filtration system. Additionally, UV lights do not attract particles to them; particles have to pass underneath the light to be affected by the radiation.

If you are concerned about biological contaminants in your home, one of the best options available for both your health and peace of mind is the installation of UV germicidal lights to your Jeffersontown AC.

Correct installation is important to proper functioning, so be sure to hire professionals, like the trained experts at Accutemp Heating and Air Conditioning. Call us today!

Why Has Indoor Air Quality Become Such a Major Concern?

August 13th, 2014

At AccuTemp Heating and Air Conditioning, we offer a range of services to homeowners to help increase indoor air quality in Louisville, KY. This includes duct cleaning, duct repair, duct sealing, and installation of air filtrations systems, humidifiers, dehumidifiers, and UV germicidal lights.

But why has protecting the indoor air in homes become so important that many professional HVAC companies now offer specific services for it? You’ve probably thought to yourself when hearing about indoor air quality: “Is the air inside my house really that bad?”

The answer to that is… yes, it can be that bad. In fact, studies have shown that indoor air can be 100 times worse than outdoor air.

This information comes to us from the U.S. Environmental Protection Agency, which has identified a decrease in indoor air quality as one of the major health threats in the country today. The EPA’s Indoor Environments Division (EID) does continuing research and education to combat the health risks from poor quality air inside homes, schools, and businesses.

The main reason that indoor air quality is under threat is that the heat sealing on buildings has significantly improved over the past few decades. To conserve energy, homes and other buildings have strong seals against the outdoor air: this means less heat loss during cold weather, and less heat gain during warm weather, resulting in improved comfort and a reduction in stress on heating and air conditioning systems. But a side effect of making homes nearly airtight is that very little fresh air can circulate through the rooms and remove the stale, dust-filled air. The stale air remains, and contamination starts to build up inside the ventilation system, creating a reservoir of pollutants that can negatively affect people’s health. The lack of outdoor ventilation also results in trapping gas particles from household chemicals and emission from appliances.

Although a home can increase its ventilation to remove some of this contamination by opening up windows and doors, this is not practical during all weather conditions and during long stretches of the year. This is where professional indoor air quality services come in handy: with the right filters and regular duct cleaning, you can vastly improve your indoor air quality in Louisville, KY.

We will find the right solution for cleansing the air you and your family breathe every day.

If you are concerned about the well being of the air in your home, contact indoor air quality experts at AccuTemp Heating and Air Conditioning.
