Reducing AC Costs | AC Repair Dallas

In this article we continue with part 2 of reducing the workload on the home’s air conditioning system, thereby increasing your comfort, reducing AC costs for your home, while reducing wear on the system, as well as the frequency of AC repair in Dallas.

Attic, Floor and Wall Insulation

Numerous American homes are deficient in insulation. This doesn’t mean a home was built substandard. It is merely a reflection in the change of insulating guidelines. As environmental change continues to occur, numerous regions of our nation are experiencing colder winters and hotter summers, making the need for adequate insulation more important than ever.

A general guideline for attic insulation is if you can see the ceiling rafters, your attic is under-insulated, and is costing you money on energy costs. In addition, the additional strain upon the air conditioning system is causing increased wear as it must run more often. The correct level of insulation in your home will increase comfort, reduce energy costs, as well as reducing the wear that will lead to an increased frequency of AC repair in Dallas.

While insulating most attics presents no problems, insulating the walls in an existing home is an entirely different matter. Unless you are remodeling and opening up the walls, it is a project with varying results. Some homes achieve the needed insulation without a hitch, while others end up with gaps and little or no benefit.

If you live in a lovely, but cold un-insulated older home and can afford it, having the old siding removed down to the walls is the best means of insulating them.

Today it is recommended for floors with a crawl space underneath, or unconditioned basement space to be insulated as well.


The ceiling may be a source of air intrusion around light fixtures. Expanding foam is a good product for sealing these holes up. Properly Insulating and Sealing Ductwork

If your duct work is located in an unconditioned space it should be properly insulated and sealed to prevent the loss of heating and cooling. Most ductwork is sealed with aluminum tape when installed (duct tape should not be used on ductwork). The tape is incredibly resistant to environmental factors, but can loosen, allowing the conditioned air within to escape. This loss of conditioned air will elevate energy costs, and increase the workload on the HVAC system, reducing its service life and increasing the need for more frequent AC repair in Dallas.

Other Air Intrusions

Air intrusions may occur around any cables, water lines, drain pipes and vents. Expanding foam is a great product to seal all but those which are hot, such as a furnace flue, chimney or gas water heater flue. These require a special high temperature sealant to avoid the risk of a fire.

Kitchen and bathroom vent fans are a potential source of significant air intrusion. Replace them with a more efficient model to save energy dollars as well as to prevent stress on your HVAC system resulting in the increased need for AC repair in Dallas.

Attic Ventilation

Attic ventilation enables the hot air in the attic to escape or to be removed. Ventilation can be passive as in vents, or active as with an attic fan. If heat from the attic is heating up your home, an attic fan is the best choice for reducing its effect in the living space. Select a model with oil ports to enable frequent oiling of the motor for the longest service life. Attic heat is one of the most common causes of an unnecessary workload on air conditioning, that results in an increase in the number of AC repair in Dallas.

Keep the area surrounding your outside air conditioning unit free of overgrown grass, weeds or any other objects that may impair its airflow. The lack of airflow will overload the unit and damage it, creating the need for AC repair in Dallas.

Reducing Air Conditioning Costs | Dallas, TX

Reducing AC Costs | Air Conditioning Repair Dallas

You can reduce the workload on your air conditioning system, as well as the cost of operating it by utilizing the following tips. As a result of implementing these tips, you will receive the additional benefit of increased comfort, as well as reducing the need for air conditioning repair in Dallas. Your home will be cooler and more comfortable and will cost you less on energy bills year round. This article contains Part 1 of reducing AC costs.

The cooling load is the amount of heat to be removed from a home by the air conditioner to maintain a comfortable indoor temperature during a worst case scenario of extreme heat, as well as during typical summer temperatures.

The factors that influence your home’s cooling load are as follows:

  • Glass doors
  • Windows
  • Sunlight entering windows, skylights, or glass doors
  • Exterior walls
  • Partitions (that separate spaces of different temperatures)
  • A rooms ceilings located under the attic
  • Roofs
  • Floors over an open crawl space
  • Air infiltration around doors, and windows, vent pipes, unsealed intrusions (such as pipes)
  • The number of persons in the home
  • Appliances
  • Lights
  • Ductwork located in an unconditioned space that is not insulated or unsealed

A number of homeowners feel their homes are adequately sealed. Unfortunately, the reality is that a majority of homes experience numerous sources of heat gain from air leaks around windows, doors, attic entry and other gaps. Furthermore, window heat gain and the lack of adequate insulation add to the cooling load and cause unnecessary elevation of the electric bill, as well as increased wear and tear on your AC system, necessitating the need for increased air conditioning repair in Dallas.

These issues can be eliminated through sealing air intrusions, increasing insulation and the routine maintenance and service of your air conditioner.

Various materials are available for sealing air intrusions throughout the home and include caulking, weather stripping, expanding foam and other products. These products are low cost, and provide benefits that far exceed the initial cost.

Insufficient insulation allows excessive heat gain to enter the home from the roof and hot attic, inefficient windows, and heat gain through under-insulated walls. A thermography scan will reveal specific heat gain and loss issues, and will enable you to add insulation where it is needed for the greatest cost effectiveness.

Providing routine maintenance to the air conditioning system will keep components operating at peak performance, which reduces the workload on the system and prevents premature failure of the components, while reducing the need for air conditioning repair in Dallas.

The single most important action a homeowner can take in caring for the air conditioning system is changing the filter routinely. A dirty and clogged filter causes premature wear and will substantially increase the systems use of electricity. Furthermore, a dirty filter can lead to the failure of components which require air conditioning repair in Dallas. Filters are available in different grades, ensure you use a type of filter recommended for your system.

If you have questions regarding the appropriate filter for your system ask your HVAC technician or your systems manufacturer.

Let’s take a look at how you can address some of these issues while reducing the workload on the AC resulting in a more comfortable home, improved energy efficiency and a reduction in wear and tear on the AC resulting in the need for less air conditioning repair in Dallas.

Glass Doors and Windows

Glass is a poor insulator, and windows are one of the common factors leading to heat gain, and the increased workload on the AC. This workload directly correlates to premature wear and the need for increased air conditioning repair in Dallasunless you have energy efficient windows some action is required to reduce their impact of heat gain and loss. The preferred choice is to have energy efficient windows installed. Not every homeowner can afford this option and you do have lower cost alternatives.

The next option is to install UV/heat blocking window film. Simple film available from home supply stores will stop heat gain from the sun. Higher grades of window film are available that are thicker and easier to handle. Some even claim to be the equivalent of adding a two pane insulated window. They all work great to block heat gain and some offer UV filtration as well.

The drawback to these products is cost, though they are significantly lower in cost than new energy efficient windows. You can purchase it for as little as $30 that will cover approximately 5 windows. The product can also be applied to glass doors and works just as effectively. Window film preserves a view, while blocking heat gain almost entirely. The products perform amazingly well, and are probably right up there with increased insulation in reducing AC workload, preventing the wear of its components and subsequently reducing the need for air conditioning repair in Dallas.

The third option is the use of drapes. Though not as efficient as window film it will help. For the best effectiveness use white or light colored drapes.

The second action you can provide with your homes windows and doors is to seal air intrusions. Around doors ensure the gaskets are intact, remain pliable for a tight seal and don’t allow gaps in the seal. Check your door with a damp hand to detect air intrusion, and view it when the sun shines on it. If you daylight is visible around the door, it is in need of sealing.

Feel around windows for air intrusions, and if your windows are leaking air into or out of your home, use caulking, or other products to seal the leaks. Homes are frequently built with a lack of insulation around the window frame. Removing the wooden casings on the wall surrounding windows is the only way to correct this lapse in carpentry.

Unsealed windows and doors allow hot air to enter the home, especially when the AC runs. These air leaks increase the load on the system, leading to air conditioning repair in Dallas.

In Part 2 of this series, we will continue our overview of improving your homes envelope to reduce both the cost of cooling your home, while reducing the workload on your AC to improve its efficiency, performance and reduce the wear that leads to air conditioning repair in Dallas.

If you haven’t had your AC serviced and tuned-up for the summer, give Garland Heating and Air Conditioning’s certified experts a call today.

Air Conditioning Capacity Dallas, TX

Air Conditioning Capacity | Air Conditioning Dallas, TX

Homeowner’s often think of air conditioning capacity in terms of tonnage, such as a 3 ton unit, for example. One ton equals 12,000 British Thermal Units (BTU’s or Btu’s); therefore, a four ton system has 48,000 BTU’s. A common misconception regarding capacity is that bigger is better, and in the following we will discuss why correctly sized equipment is important for air conditioning in Dallas, TX.

Homeowners often think that having greater capacity than required air conditioning in Dallas, TX will provide a more comfortable home since it brings the inside temperature more quickly, but this is not the case. The size of equipment required will provide a comfortable temperature on the hottest summer day, but if your air conditioning in Dallas, TX provides too much cooling, your air conditioning can do more harm than good.

An air conditioning system provides two functions. First, the cooling of your home by removing heat and the second is to remove humidity. Each time the air conditioner runs it is also removing humidity from the air. This is the water draining from the condensate pain to the outside of the home.

This is due to the ability of hot air to retain more moisture than cooler air. In the air conditioning system, as warm, moist air from inside the home is pulled through the air return and moves over the cold evaporator, the moisture condenses on the coil, where it drops onto the evaporator pan and drains out of the house through the condensation line to the home’s exterior.

An air conditioner cools the home by the removal of heat faster than it can reduce the humidity. This means the system has to run longer in order to remove moisture from the air. It is a critical function, without time to remove the moisture your home feels sticky, and warmer than it actually is. Even worse, if an adequate amount of humidity is not removed mold and mildew can become an issue in your home.

This is the reason it is important to have properly sized air conditioning in Dallas, TX. A system that is too large will cool too quickly and shut off, without removing adequate moisture from the air. A system that provides adequate cooling and controls moisture will obtain a humidity level in the range of 50 percent or lower.

Air conditioning in the past was unable to measure humidity or control run time for optimum humidity control. Today’s technology provides a more flexible means of humidity control by adapting run time to the time required to remove humidity. In other words, older systems may control temperature and humidity when the outdoor temperature is 95, but may be running too little to remove adequate humidity when the temperature is 85, for example.

Dual stage, or variable stage equipment will operate at a low as well as a high speed, or at a speed in between in the case of variable speed equipment, meaning that this type of air conditioning in Dallas, TX will provide a comfortable environment with less humidity.

In addition, two-stage or variable speed equipment will provide the added benefit of saving you money by reducing your electric bill since less energy is required at lower capacities. These systems of air conditioning in Dallas, TX are ideal for the regions of the hot and humid southern states.

In summary, an appropriately sized system, with the added benefit of a dual or variable speed system will provide the optimum comfort with humidity control of your home. A system that is larger than you need create a negative impact upon your comfort, just as a system that is undersized will be overworked, and will experience a shortened service life, as well as being unable to cool the home adequately during hotter weather.

Garland Heating and Air Conditioning’s highly trained and experienced HVAC technicians will ensure that your home receives the correct size required. There are numerous factors involved in selecting the appropriate size system. Square footage of the home is only one factor, the direction faced, number, size and type of windows are another factor, the degree of insulation and other considerations are factored in to establish the correctly sized of air conditioning in Dallas, TX that your home requires. Give us a call, we will provide the professional installation you desire for the ultimate comfort in your home.
