Winter HVAC Tips Dallas

With cold weather already making an appearance in the Dallas area, we thought we’d provide some winter HVAC tips to help you stay warm with and prevent the need for heater repair. You can view our HVAC Specials or contact us for more information.

Operating a dirty furnace or one that isn’t properly tuned can cause damage to the furnace. It will definitely cause your utility bills to be higher because the HVAC system will have to work harder to produce the desired temperature.

While we recommend you call a professional to provide a full diagnosis of your system, there are a few items you can check yourself.

  1. Before performing any maintenance, turn off the system and wait for the blower to stop.
  2. Check your air filter and replace it if needed. We recommend you replace the filter every spring and every fall. Check the filter monthly between changes to make sure it isn’t dirty.
  3. Move any object around the furnace to different locations. Items around the furnace can be a fire hazard and cause an obstruction in the air supply
  4. Listen for noises while your heater is running. Furnaces that aren’t running efficiently often produce odd noises. Set your thermostat to HEAT and turn it up above the current room temperature. Wait for the unit to come on and listen for any odd noises.
  5. Pay close attention to any unusual odors, especially if you have a gas furnace.

Don’t forget to turn your heat down when no one is home, fill any cracks in your doors or windows, put weather stripping around doors or windows and use a space heater where possible.

If you have any concerns or questions about your furnace or HVAC system, contact us today. We serve the entire Dallas area, including Highland Park and University Park.

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.

Attic Fans Dallas

Attic ventilation may not be at the top of you mind, but it is an aspect that can help keep you home cool and efficient. Attic fans used in the Dallas area are often installed with humidstats as well as thermostats. Since humidity is common in the Dallas area, an attic fan with a humidstat is a good choice. Attic fans are a great way to improve your home energy efficiency. Radiant Barrier and high efficiency A/C units are other options for improving the efficiency of your home and saving on utility costs.

If you attic is not properly ventilated, it will store hot air. The hot air can reduce comfort and increase your utility bills. The answer to this hot air is to install an attic fan. Attic fans are inexpensive and are designed to only run when needed.

On average, a home should have 1 sq ft of attic ventilation for every 300 sp ft of attic space. If you’re not sure if you attic is getting too hot, you can see some visible signs on your roof. Look for shingles that have the corners turned up or bulges in the felt. In the cold winter days, you can check for frost inside the attic. In addition, check your soffit vents to make sure they aren’t clogged with debris. Any clogged air vents should be cleared to help the attic breathe properly.

When choosing at attic fan there are several things to consider. There are two basic types, those designed for a roof mount and those designed to be mounted on a gable wall. In the Dallas area, a roof mount is the most common attic fan installation. There are many variations of these types of fans.

Traditional Store Type Fan

A Traditional Store Type Fan can be used to move a lot of air. However, they do leave a hole in the roof that isn’t insulated. These attic fans are also noisy and require maintenance.

Solar Powered Attic Fans

Solar Powered Attic Fans are one of the best options. Not only are they powered by light, but they are very quiet. The overall cost of these attic fans are also less and the maintenance is very low. If you live in an area where sunlight might not be visible for several days, it is possible that the solar powered attic fan will stop running when needed due to low power. However, that is rare in the Dallas area since we have routine sunshine all year long.

Electric Attic Fans

Electric Attic Fans are another option and, as you can tell by the name, they are powered by electricity. They involve a little wiring and will increase your utility costs, especially in the summer when the attic fan is frequently used.

Wind Powered Fans

Wind Powered Fans rely on natural energy to function. You have to install turbine vents to allow wind access, but they are a great option for those trying to go green.

If you have any questions regarding your attic temperature, overall home efficiency or whether you need an attic fan for your home, please contact us today. We offer FREE Home Energy Audits and can provide you with an evaluation of your homes energy efficiency.

How to Keep Cool in Summer Heat

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.

Radiant Barrier Dallas

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.
