Is Poor Air Flow Design Attacking Your CPS Energy Bill & Savings?

Air Conditioning & 300

In the movie ‘Three Hundred’, the Spartans held back the Persian Army, the most powerful army in the world at the time, from entering their country because of a pass too small for a lot of men to enter. This restriction created the opportunity for a small force to compete with an army that was much larger. The same basic concept is true in the home air conditioning system. Installing a new high efficiency system in your home is like the Persian Army trying to invade, with the efforts being thwarted by too small of a pass to fit through. The army, now being air flow, cannot get to the battlefield; the rooms in your house, no matter how great the system can’t win the fight against heat and humidity.

Home Comfort System: Each Component Matters

The home comfort system is only as good as the corridors that carry the air. The system must be designed so that it gets the air to where it needs to be, with the proper force and velocity to overtake the enemy. Under-sized returns, improperly sized supply trunks can hold back the cool dry air from doing its job removing heat and humidity. The design phase is extremely important. If your system is not designed properly, meaning system sizing as well as duct work, you are going to be left with hot and cold spots, uncomfortable rooms, utility and repair bills that are higher than they needed to be. This means that you could be replacing the system before its time to do so.

Existing Home Update Example: Correcting Poor Design

ac repair air returnOriginal return air design for this 1967 San Antonio home were too small for the system. The home owner was frustrated with the AC company who installed the system due to the lack of performance and mold starting to form on the outside area of the evaporator coils. After testing and calculating we determined air velocity was insufficient for the unit which was allowing mold to grow and not cooling the home efficiently.

The new air returns we installed were larger and contain a slow for the air filter. We added an additional air return as seen in the featured image. The larger returns allow the correct amount of return air to enter the system. With the filters in the grills the air is sucked in from the rooms into the cavity under the closet and up through the system with enough velocity to treat the mold issue.

We Don’t Guess, We TEST!

TASCO runs a heat load on our replacement systems to ensure it is properly sized. We also perform a flow hood test, to see how efficiently your duct work is supplying air to each area of the home. These measurements and calculations are paramount in the efficiency and comfort the new system will provide. If we don’t calculate how the supply and return ducts affect the efficiency and just replace an old aging system for a new hi efficiency system, you are only going to enjoy a fraction of the comfort and cost effectiveness that the system is designed to provide.

So when you are thinking about replacing your system, or you begin noticing that you have uncomfortable rooms in your home, make sure any HVAC contractor that comes to give an estimate looks at all the variables that are involved with efficiency and comfort, now you know what those factors are. And everyone remember; ‘If it has to be right it has to be TASCO’.

Repair Your Duct System to Maximize Efficiency

One of the most important fixtures of any home is the home’s heating and cooling system. Modern advents in technology have led to both simpler, more efficient systems and more informed homeowners. However, even the most educated homeowners are sometimes uniformed about how important their duct system is. The furnace or air conditioner can often be thought of as the star of the show; they generate the conditioned air that keeps a home comfortable. But if the conditioning units are the stars of the show, there simply wouldn’t be a show without the ducts. In San Antonio, whatever the season, homes need conditioned air flowing through them in the most efficient ways. However, duct repair is often neglected, if it is considered at all. Why? According to EnergyStar, 20% of conditioned air leaks out due to ducts needing duct repair. The result isn’t academic, as homes in San Antonio and everywhere else can see higher utility bills and less comfortable homes as a result. Ducts needing duct repair can be spotted by looking at a few key factors.

Foremost among the signs that your San Antonio home needs duct repair is high energy bills; duct repair can help bring high energy bills down by efficiently delivering air throughout your home without leaks in the blistering San Antonio summer or the chilly San Antonio winter. Another sign that your home could benefit from duct repair is the consistent difficulty to heat or cool specific rooms. Since homes needing duct repair cannot distribute air efficiently, these cold or warm spots will be hard to rid your home of. A kind of corollary to this problem in a home needing duct repair are stuffy, stagnant rooms that don’t seem to get air of any kind. This duct repair sign can make your home incredibly uncomfortable and put it a risk for more work needing to be done. Another sign of needing duct repair in a San Antonio home is if your ducts are in the attic, crawl space, or garage of your San Antonio home. The last sign of needing duct repair is the presence of tangled or kinked ducts, which can restrict air flow.

Whether your home is located in San Antonio or anywhere else, duct repair can be instrumental to keeping it comfortable. Vigilance for these signs and regular inspection by a duct repair specialist can ensure your home is comfortable.

Flow Hood TestLet’s put ourselves in this home owner’s shoes.

My house was not comfortable and I didn’t understand why. My current AC repair technician couldn’t figure out what the problem with my air conditioner is after several very expensive service calls. I begin asking around about more reputable San Antonio air conditioning repair companies. My friend referred me to their ac repair company called TASCO.

One of their technicians came out the same day I called to see what the problems were with my air conditioning system. The technician came in and discussed a list of questions called Comfort Concerns with me. The comfort concerns list asked questions such as; “Are there any areas that get too warm or too cold?” “Does anyone in your family suffer from asthma or airborne allergens?” “Are you concerned about future energy costs?”

I mentioned that there were several rooms in my house that are hotter than the others and the first technician couldn’t figure out the problem. The TASCO technician asked to perform a test called the Flow Hood Test to see how well the air conditioning unit was working in my house.

I watched as the technician placed a funnel type structure called the flow hood over the supply register. The flow hood measures how much air is coming in through the supply air vent to see how much air was coming out. He repeated this process on every supply register in my house.

After testing each area we sat down and discussed the results. The technician explained to me that the duct work was under sized and it must be correctly sized installed so that the system will run efficiently and provide greater comfort.

The following day, two TASCO technicians arrived on time at my house ready to install new duct work that qualified for rebates. Within a day’s time, my system had new duct work and my house finally was comfortable and livable.

I now know why my friend referred me to TASCO. After this quick and efficient experience with TASCO I will continue to trust and call TASCO for my air conditioning repair needs.
