HVAC-The Decision to Repair or Replace Garland Heating and AC Services in Dallas, Texas

Daniel Reichert - Tuesday, March 28, 2017

With the rising cost of energy you may want to consider a new heating and cooling system in Dallas, Texas. The following information can help you decide whether to upgrade to a new system, or correct problems that affect your current system.

First, if your system is more than 10 years old consider a new one. Newer models will have much improved energy efficiency and new features to increase your comfort. Consider the following when making your decision:

Your equipment needs frequent repairs: age can affect efficiency and age can cause more frequent break downs.

You leave your thermostat set at one temperature: Consider a new programmable thermostat. You can program temperature changes when they are needed. For example, program your thermostat to 65 at bedtime in the winter, and when the occupants are all gone. Multiple changes can be programmed, ultimately saving you money.

Some rooms are too hot or too cold: Problems with your ducts, inadequate insulation, or inadequate sealing may be the cause. Check ducts for joints being sealed and the ductwork for being insulated. Check any location where wire, pipes or duct exits the walls, basement or foundation. With the exception of a hot flue use latex expanding foam or caulk to seal holes. Duct problems and inadequate sealing cause your system to overwork.

Excessive Dust or high humidity: Your equipment may be poorly operating; the wrong size system or leaky duct work can all cause these problems. Dirty ducts can cause an excess of dust as well. Have duct cleaned every 10 years or more often as needed. Change your filter every month.

Know the energy star rating of your equipment: If your equipment rating is less than 5 replace it. Go to www.energystar.gov for an analysis of your home. The higher the rating the more efficient it is.

Your best defense against high energy cost is a new energy efficient model coupled with a well-insulated and sealed house. The money you save will pay for your new system. An energy efficient central air unit can save you as much as 75% when compared to a 20 year old model. Reducing our carbon footprint goes hand in hand with energy efficiency.

Choose the correct sized equipment: Having a bigger system won’t save you money. It may cost you more. A bigger unit will cycle more often, never reaching its peak efficiency. It will be unable to remove humidity from the air. Remember, humidity makes it feel warmer.

Your tonnage need may be different than your old system. If you have added insulation, new energy star windows, and sealed air leaks, your system needs may be smaller. Your old equipment may have been too large in the beginning. Also, if you have a new addition, this will change your system needs. Your contractor will need to gather the following information about your house: floor area, level of insulation and type and size of windows.  He will do this by performing the following:

  • Measure the square footage of your home noting the direction it faces
  • Measure the square footage of windows and doors and note the direction they face
  • Look in the attic to estimate the value of the insulation
  • Look in basement or crawl space to estimate the value of the insulation
  • If possible, look into the walls to estimate the value of the insulation
  • Look at the duct system for leaks and estimate insulation value
  • Note the number of appliances
  • Note the presence of any leakage from a fireplace
  • Note the number of bedrooms for fresh air needs
  • Note the temperature you plan to keep your home

A professional will calculate these things, so be careful that your contractor is licensed, and insured. Sizing is the most common mistake according to national surveys. Many installers simply replace the same size as your old system without considering changes made to your home or the increased efficiency of new systems. Your contractor can use an ACCA/ANSI Manual or the equivalent sizing tool that takes all the above and other factors into consideration including proper size duct. Computer software is also available to contractors to calculate your home’s needs.

Choose a high efficiency Energy Star rated system for the best value and the least impact upon the environment.

If your system is not ten years old or older, you may want to beef up your home by sealing it, installing energy efficient windows and doors, and adding insulation. Even sun blocking window films or awnings can help.  Reflective blinds and drapes can also assist your wallet. Open the curtains on sunny windows in the winter and close them to the sun in the summer.  Consider installing a programmable thermostat, lower it to 68 degrees during winter days and wear a sweater. Raise it to 78 degrees in the summer and turn on ceiling fans and other fans. Using a humidifier in the winter can make it feel warmer. Rugs on cold floors can make you more comfortable in the winter.

Certainly, have your system checked and serviced every year. The old saying that an ounce of prevention is worth a pound of cure certainly does apply to your homes heating and cooling. Clean coils make for a more efficient system.

If you’re still in doubt, your HVAC contractor can advise you on whether you should correct any problems with your old system, or invest in a new energy efficient system for your home.

A Guide to Insulation in Dallas, Texas | Garland Heating and AC

Daniel Reichert - Friday, March 24, 2017

Having adequate insulation is one of the most cost-efficient ways of saving energy dollars and reducing energy waste. By investing just a few hundred dollars in weatherization and proper insulation you can increase your comfort level while saving as much as 30% on your heating and cooling’s use of energy in Dallas, TX.

Insulation is used in the attic, walls, floors, basements and crawl spaces. Check your insulation in these areas to see if it meets recommended levels for your region. Insulation is measured in R-value-the higher the R-value the better your home will be insulated.

Insulation is made from many different materials, but usually comes in four types-batts, rolls, blown loose-fill, and rigid foam boards.  Batts are made to fit between the studs in your walls, or between ceiling or floor joists. Batts are usually made of fiberglass or rock wool.  Batts are the most common form of home insulation and it is also one of the least expensive.

Rolls or blankets are usually made of fiberglass and comes in three types, faced, unfaced thermal or sound insulation.  It is also available in multiple densities and thickness so that it can conform to various-shaped spaces.

Loose-fill or blown, is usually made of fiberglass, mineral wool or cellulose, and is blown into the attic or walls.  These materials are manufactured from recycled waste materials.  Cellulose is mostly made from recycled newspaper. Fiberglass contains anywhere between twenty to thirty percent recycled glass. Mineral wool is typically produced from 75% post-industrial recycled content.

Rigid foam boards are lightweight, provide structural support, and generally have an R-value of 4 to 7 per inch. It is made to be used in confined spaces such as cathedral ceilings, concrete slabs, foundations, basement and exterior walls. Some manufacturers recommend its use under metal roofing and behind siding.

Some signs your home may be under insulated are as follows:

  • Uncomfortably hot in the summer and cold in the winter;
  • If you have noticed excessive noise from the outside intruding into your inner home;
  • Excessive cost of energy bills;
  • If your home was built before 1980 it probably is under insulated.


To determine if your attic has adequate insulation measure the thickness of the insulation. If there is less than R-19 (6 inches of fiberglass or rock wool or 5 inches of cellulose) you will benefit by adding more insulation. Adding attic insulation is the easiest way to add cost effective insulation if you can't insulate everything at once. If cold winters and hot summers still intrude in your home you probably should insulate your walls next. This is more expensive and usually will require a contractor to do it for you. It can pay for itself in energy savings, especially if live in an extremely hot or cold environment.

Crawlspace insulation is recommended only if the crawlspace is dry year round, the floor above is not insulated and there is no ventilation in the crawlspace. In addition, a vapor barrier of 6 mil polyethylene film should be installed on the ground to prevent moisture intrusion in to the crawl space.

Windows, doors and skylights are another area that energy is lost. Look for energy star products and consider the directions they face. Depending upon your area, north facing windows will receive more cold exposure and south facing windows can receive more heat exposure in the summer.

Ultimately, when planning a remodel, addition or even building a new house-it is to your benefit use energy efficient products to save energy and money.

Don't let your project cost you more by wasting energy. Your contractor is your best source for energy saving solutions, products and a professional installation.

Commercial HVAC System | AC Repair Dallas, Texas

Daniel Reichert - Wednesday, March 22, 2017

A commercial HVAC system works extra hard, so providing routine maintenance and  changing the air filter routinely, is essential in receiving the optimum energy efficiency, performance and ensuring a long life span. Whether you own or rent the building, you are responsible for the electric bill, and changing the filter as recommended is one important step that helps to save you money. Contact Garland Heating and Air Conditioning to schedule an AC repair in Dallas, Texas.

Regular Maintenance

Providing routine maintenance of the AC system helps to prevent breakdowns and problems with the system. Furthermore, when you schedule a professional service at the annual or biannual schedule as the recommended, the benefits are multiplied, along with the lifespan of the system.   

Monthly Tasks

Choose a day to perform regular maintenance on the AC and mark it on the schedule. Select a high quality air filter approved for use in your unit by the manufacturer. The filter helps to protect the evaporator coil from the dust that can impair its performance. Routine maintenance by your HVAC technician will allow the coil the be cleaned when required, ensuring its performance and optimal efficiency.

The Annual Inspection

Schedule an annual air conditioning service now, if you haven't already. Your Garland Heating and Air Conditioning technician will provide a comprehensive inspection and service.  If your commerical unit is a heat pump, remember they require biannual maintenance, spring and fall, because the heat pump works twice as hard to provide both heating and air conditioning year round. 

Protect Your HVAC System from Remodeling Dust and Debris

A remodeling project can promote your business and make customers more comfortable in their shopping experience.  However, during a remodel project you should take extra care to protect your vital HVAC system from the dust and debris remodeling causes.  

A running system and open vents allow dust and debris to be pulled into the system. Dust not only coats the coils and impairs performance, it creates friction in moving parts causing wear, and can impair electrical contacts. Not protecting the system can result in AC repair in Dallas, Texas. The easiest way to protect the system is leave it turned off during t

he remodel and duct tape the registers closed from the dust.  If this isn't possible tape up the registers in the affected area. When remodeling will affect the layout or size of a space, it's always best to talk to your HVAC contractor before remodeling begins. This can prevent hot or cold spots affecting your employees or customers' comfort.

Reducing the Effets of Construction Dust

Construction dust during a remodel seems to get into other areas, despite your best efforts. Fiberglass filter pads are an option for wall vents that won't break the bank. Unfortunately, they are not a good solution for floor vents because debris is heavier on the floors and the filter will not keep all particles from entering. Taping floor vents off is still the best solution.

Finally, during construction change the air filter every week or two during the project. Once the project is complete, contact Garland Heating and Air Conditioning for an HVAC inspection to ensure your efforts were successful in keeping the system clean. Otherwise, the need for  AC repair in Dallas, Texas may result.

Commercial Air Conditioning Installation

Eventually, even a well maintained system will require replacement.  As the system ages, it is likely to continue to cost you for AC repair in Dallas, Texas. Furthermore, a 15 year old system is going to cost you more on energy, than a new one. A new system may even help to pay for itself in time on energy costs, especially if you select an Energy Star approved model. The question business owners often ask is, when is it time to replace the unit? When you are contacting your HVAC technician several times a year for AC repair in Dallas, Texas it would be more cost effective to just replace the air conditioning system. A newer, more energy efficient system can save you money, and provide greater reliability. In addition, when the AC appears to no longer maintain your comfort, it is a sign of weakening components, and the need for replacement.
