4 Things that Can Hurt Your Dallas AC Unit

As we help our customers in the Dallas area with AC Repair, AC Maintenance and the installation of new air conditioner units, we see many homeowners doing things that can hurt their AC unit. Some of these items they do on a regular basis, probably without knowing it. Other items are a little harder to determine and probably outside the knowledge of the average homeowner in the Dallas area.

Bad Air Ducts

Leaky ducts are a major cause of AC units failing. Ducts move the air through your home and are housed in the attic of most Dallas homes. If you have a duct leak, cold air is slipping out into the attic and it isn’t reaching the desired destination….you. There is definitely a particular way a duct should be put together, so make sure yours is done properly or hire someone knowledgeable to check for you.

Not Enough Air Conditioner Refrigerant

When your home isn’t as cool as you want it to be, it is usually do to the AC unit having low refrigerant. We get many calls at the beginning of the summer from customers saying their AC is running, but the home isn’t cooling as much as it should. There could be several issues that are causing this, but many times it is because the AC unit is low on refrigerant. If you have the wrong amount of charge in your Dallas AC unit, it can cause a 20% to 30% decrease in efficiency for the unit.

Using the Wrong Air Conditioner Filter

Most Dallas homeowners know that they need to change their air filter on a regular basis. However, many will change it with the wrong filter. Be sure to check the compatibility of your filter before you install it. If you install the wrong type or size, it will cause your AC unit to struggle and become less efficient. In some cases, if the filter is not allowing proper air flow, the entire AC unit will shut down. You can avoid this by getting a quality air filter for your AC unit.

Eastin Air offers FREE Home Energy Efficiency Audits and can assist you will all of your HVAC needs in the Dallas area. Call today to schedule your appointment for any of your air conditioner needs.

A/C Repair and Maintenance

A/C Repair and Maintenance Season is just around the corner. The temperatures in Dallas are starting to go up and many people have probably started running their air conditioners already, at least for parts of the day. You can view a few items on Why to Maintain Your A/C Unit.

We’d also like to remind you that A/C units are just like cars, they require maintenance to run efficiently, correctly and for a long time. A car receives several oil changes, tire rotations, wheel alignments, filter changes, etc. in the course of a year. Your air conditioner needs maintenance as well. In most cases one check spring and fall will keep your air conditioner and furnace running smoothly and lasting a long time.

Those that chose not to have their air conditioner checked or maintained properly are running the risk of higher utility costs and shortening the life of their A/C unit. When an A/C unit isn’t maintained it begins to use more electricity because it isn’t running efficiently. That can lead to parts breaking, filters clogging, coils rusting, etc.

If you want to make sure your A/C unit runs smoothly and lasts for years to come, maintain it. Every spring and fall have one of our A/C technicians perform a checkup of your system. We’ll fix any issues, provide routine maintenance and make sure your A/C unit is running smoothly to keep you cool at an affordable price in the summer heat.

Call Eastin Air today to schedule an appointment.

Summer is here in the Dallas area and Eastin Air is ready to help keep you as cool as possible. We offer A/C repair, A/C Maintenance, A/C Installations, Radiant Barrier, Attic Ventilation, Solar Powered Attic Fans and much more.

During the hottest periods of the summer, it is important to do all you can to help relieve some of the stress and work that your air conditioner goes through. Making sure your home is running efficiently helps keep your air conditioner running longer.

Radiant Barrier offers a permanent solution for reducing heating and cooling costs. Using radiant barrier can lower your attic temperature by up to 30 degrees, improve your HVAC duct performance by 50% and improves the efficiency of your insulation by up to 15%. All of these things combined help your A/C unit work less, saving you money and prolonging the life of your air conditioner.

A/C Maintenance is another item that helps prolong the life of your air conditioner. Air Conditioners are just like cars…they need maintenance and attention on a regular basis to run properly and last a long time. The better care you take of your unit, the better it will run and the longer it will last.

Solar Powered Attic Fans can also add to your electric savings and help your air conditioner last longer. While solar powered attic fans do cost a little money, they typically pay for themselves in 1-2 summers.

Regardless of your budget, there is something you can do to your home to make it more efficient and help save on your utility costs. Eastin Air provides a FREE Home Energy Audit to help you determine the areas of your home that need attention. Even something as simple as sealing air duct leaks can add up to a significant savings over a few months of summer heat.

Radiant Barrier Savings

In our continued effort to help educate our customers on how radiant barrier works, the science behind it and the different types of radiant barrier, we are now going to focus on the savings radiant barrier provides.

Many Dallas individuals want a hard number or percentage of estimated savings from a radiant barrier, it really is impossible to predict, because there are so many different factors which contribute to its effectiveness or ineffectiveness. However, according to studies done by the U.S. Department Of Energy, it is generally accepted that installing radiant barrier in the attic will reduce heat gain through the ceiling by 40% typically leading up to a 17% reduction on heating and cooling utility bills.

While this 17% figure may hold true for many climates and a typical installation, it will vary from place to place. Many independent studies and radiant barrier users have tested their results and reported energy savings varying from as low as 12% up to as high as 39%.

The graph below shows the attic temperature difference between two similar attics spaces, one with a radiant barrier installed and the other without. As you can see, the attic with the radiant barrier(blue) stayed much cooler throughout the day.

This report is not meant to give hard figures, rather it is meant to give the potential radiant barrier user/installer the proper information to make the most informed decision possible. With that being said, the section below will list and describe some of the main factors which will affect the performance of a radiant barrier installation.

Main Factors Determining Radiant Barrier Effectiveness:
Attic Ductwork – If ductwork or air handlers are located in the attic, the temperature of the attic area will affect the efficiency of the HVAC system. Using a Radiant Barrier to control attic temperatures will increase HVAC system efficiency, thus reducing energy costs.
• Existing Insulation – If existing attic insulation is less than a R39, a Radiant Barrier installation will help to stop excess radiant heat. Homes with a R39 or higher ceiling-insulation, and have no ductwork in the attic will not achieve much energy savings from a Radiant Barrier installation.
• Cold Climates – In climates where the majority of annual energy usage goes towards heating the structure, a radiant barrier on the floor of the attic, above the insulation and ductwork will provide substantial energy savings.
• Hot Climates – In climates where the majority of annual energy usage goes towards cooling the structure, a radiant barrier stapled to the bottom of the roof rafters will provide maximum energy savings.
• Mild Climates – In more mild climates where neither heating nor cooling is used much, a radiant barrier installation will not create massive energy savings. However, the Radiant Barrier can increase the overall comfort of the structure while providing small to moderate energy savings.

Radiant Barrier – How Does it Work?

How Does Radiant Barrier Work?

In our previous article about Radiant Barriers, we discussed heat transfer. In this article, we’ll discuss how a radiant barrier stops heat.

Eastin Air offers radiant barrier installation as well as eduction on foil radiant barrier vs. spray on radiant barrier.

B: How Radiant Barriers Stop the Heat
A radiant barrier is a material with a very low emissivity and high reflectivity giving it the ability to virtually stop the transfer of radiant heat or thermal conductivity. This allows the radiant barrier to reduce heat gain in the summer and heat loss in the winter, thus reducing the net heating and cooling needs of the structure.
There are two key values that determine the effectiveness of a radiant barrier, and those are its reflectivity (higher is better) and emissivity (lower is better) values.

The reflectivity value of a radiant barrier is pretty easy to understand, the higher the reflectivity value, the more light energy (heat) the radiant barrier is able to reflect.

Reflectivity values are expressed as a percentage number (%), which basically describes how much light energy the surface will reflect. The emissivity value is basically the ratio of heat energy radiated by a material to the heat energy radiated by a true black body at the same temperature. This may sound a bit confusing, so let’s talk in layman’s terms. Basically, if we were to take a pure black object (theoretical) which reflects no light energy and absorbs all light energy that touches it, it would have an emissivity value of one ( = 1). Any real object, weather it is black or not would have an emissivity value of less than 1. So, what this definition is really saying is that the darker an object is, the more light energy it will absorbed and re-radiated. And subsequently, the lighter and more reflective a material is, the less light energy it will absorbed and re-radiated. Radiant barriers, even though they have little or no “insulation” properties can effectively block most of the heat coming in or leaving a structure. This is because radiant heat is the most efficient type of heat transfer, and stopping radiant heat transfer is the most effective way to decreasing your heating and cooling needs. In the summer, less radiant heat entering your attic makes your AC system run more efficiently, and in the winter, less heat energy being lost through the roof makes your heater more efficient.

In our next post, we’ll talk about what type of savings you can expect from a Radiant Barrier. Eastin Air proudly serves Dallas and surrounding areas. We specialize in Highland Park and University Park.

How Do Radiant Barriers Really Work?

To help you to understand how a radiant barrier works, let us first start by explaining a little about heat transfer. When talking about radiant barriers, insulation, HVAC systems and energy efficiency, it is important that we recognize that all of these things are about controlling heat.

You can also read a summary about what radiant barrier services we offer on our Radiant Barrier page.

There are also different types of radiant barrier, foil barrier and spray barrier. You can read a previous post about the difference between the two: Foil Radiant Barrier vs. Spray On Radiant Barrier

If you were wondering why you might need radiant barrier, it might be helpful to read our post before you read the remainder of this article. Why Radiant Barrier?

A: Understanding Heat Transfer
Heat transfer happens in homes and building in three distinct ways.
* Conductive heat transfer (conduction)
* Convective heat transfer (convection)
* Radiant heat transfer (thermal radiation)

Conduction is the least efficient method of transferring heat, and in a kitchen analogy, that would be an equivalent of boiling water in a pot over a stove. The fire heats the pot and the pot transfers its heat to the water and the water eventually comes to a boil. The key point here is that conduction is the transfer of heat through
direct physical contact.

Convection is more efficient than conduction, and in our kitchen analogy, convection would be the use of an oven to heat food. Convection heat transfer is the process by which heat is circulated in an area through the air and/or fluid. The key point here is that heat is transferred through air circulation.
Radiant heat otherwise known as thermal radiation is the most efficient type of heat transfer and the best example in our kitchen analogy would be the use of a microwave. Radiant heat is generated when heat from the movement of charged
particles within atoms is converted to electromagnetic radiation. In a home or building, radiant heat refers to heat radiated from objects and materials, such as incandescent lights, concrete flooring and the sun. It is also important to note that radiant heat moves through the air without heating the air, instead it will heat the first surface that it touches, and this surface will then re-radiate that heat in the space making it feel warmer when you are in that space.

In general, heat transfer between the interior and exterior of a home or building is bad and decreases the efficiency of the heating and cooling system. There are some special conditions where heat transfer is used to increase the efficiency, such as traum walls, thermal masses, and other natural heating and cooling techniques.
But for the most part, in a typical home or building which relies on mechanical means of heating and cooling, heat transfer is the enemy.

So, it makes sense to stop as much heat transfer as possible. This is why insulation is used in all structures. Insulation is great at reducing convective heat transfer, while also reducing some radiant and conductive heat transfer as well. However, the typical amount of insulation in a home or building (anything below R39) is
simply not enough to stop the majority of radiant heat from infiltrating the structure.

Winter Heating Tips

Eastin Air offers many services that can help insure your home is operating at a high level of efficiency and that it is operating safely for winter weather. We seal air leaks, offer Home Energy Audits, Blower Door Tests, Duct Cleaning and Radiant Barrier to name a few.

With colder weather already hitting the Dallas area, we decided to provide a few winter heating tips. Some of these will relate directly to your home heater or furnace and other winter heating tips will relate to portable units.

  1. Keep anything that can burn at least three feet away from your furnace, fireplace, portable heater or wood stove.
  2. Have a three foot “kid free” zone around portable heaters and fireplaces.
  3. Never use your oven to heat your home.
  4. Remember to turn your portable heating units off when going to bed or leaving the room.
  5. Test smoke alarms monthly.

In addition to these tips, it is recommended that you have your heater or furnace inspected annually. With your home heater or furnace inspected, you can be assured that your heating system will work properly and efficiently through the winter season.

In addition to having your heater professionally serviced, it is a good idea to check your chimney, check your heat exchanger, inspect ducting and piping, check safety devices and your carbon-monoxide detector.

Heating Tips Dallas Winter

Easting Heating & Air serves the entire Dallas metroplex, servicing, installing and repairing heating and A/C units. With winter not too far off in Dallas, we thought we’d share some heating tips to help you save some money. Maintaining a lower temperature, proper insulation, sealing air leaks and lowering your water heater temperature are all good items to consider.

One of the easiest ways to save money on your heating costs is to simply lower the temperature in your home. Reducing the thermostat by just one degree can save around 3 percent on your home energy bill. For those that can’t do with the decrease in heating temperature, lowering the temperature by 10-15 degrees while at work can help you save about 10 percent. You can add another 10 percent if you lower the thermostat by 10-15 degrees overnight.

If you don’t have a programmable thermostat, we can come out and install a thermostat that will allow you to program the temperature of you home according to the time of day.

In addition to saving on your air heating costs, you can also save on your gas bill or electric bill by reducing the temperature of your water heater. Most water heaters are set at 140 degrees.  You can turn it down to 120 degrees without noticing a difference in your water temperature or the time it takes for you water to heat.

Proper insulation is imperative to keeping your home warm in the winter. Eastin Air can install new insulation in the attic or complete a free Home Energy Audit to determine if you have any areas of concern.

In addition to proper insulation, air leaks need to be sealed. Sealing air leaks is a quick service that will have a huge benefit on the integrity of your home, your energy bill and general warmth of your home. If air is leaking out, the heat is leaving your home, causing your heater to work harder and costing you more money.
