Air Duct Leaks – Is It Happening In Your Home?

Wednesday, February 10th, 2016

AIR DUCT LEAKS – HOW A LEAKY DUCT SYSTEM AFFECTS YOUR HOME AND UNIT

    Air leakage in your duct system can have a poor effect on your heating or cooling unit, reducing the efficiency, lifespan, and performance of the system.  Air duct leaks can increase your energy bills, create excessive dust, and cause poor indoor air quality.

    In order to fully understand how air duct leaks and a leaky duct system can affect your unit, it is important to know how the duct system works in conjunction with the unit to heat or cool your home.  We will use the example of cooling your home, rather than heating, because we have such harsh summers it helps put things into perspective.  When you turn on your A/C at the thermostat during the summer, the unit turns on and a motor turns a fan to suck air through the “return” ductwork to the inside of your unit.  The air from inside your home is sucked in through that “return” duct and passes over a filter to catch dust particles. The air is then blown over a coil that is made of copper and aluminum, and looks similar to a giant radiator.  That coil has refrigerant inside of it that cools the coil ice cold in the summer.  The air gets sucked through that coil and cooled down.  After the air gets sucked through the coil and is cold, it gets pushed out the other side of your unit into the “supply” ductwork.  The ductwork is either made of metal tubes or rectangular boxes that are connected together in sections, or it can be flex tubes that are like a giant slinky wrapped in insulation, or sometimes a combination of both.  The air travels through the “supply” ductwork and is spit out of all the different registers in your home.  

    You also have a “return” duct that connects to a filter box and grill.  Some homes have multiple return ducts, each connecting to a box with a filter grill.  In many cases, those “return” boxes are leaking at the seams and at the main collar connection where the ductwork is attached to the box.  The return ducts may also be leaking at various connections in the ductwork, and at the main connection at the unit.  The unit should pull air from the inside of your home over the filter to remove particles, and blow it over the coil to be cooled and distributed throughout the home.  If the return ducts have leakage it causes some of the air to bypass the filter.  That means that the unit is sucking in some air from your home and the filter is catching the particles, and some of the air is sucking in through all of the seams, gaps, and holes in the “return” ducts from the attic.  That attic air is full of dust and debris, as well as fiberglass insulation that you don’t want to breathe.  Also, the attic air is usually between 120-170 degrees in the summer, much hotter than the 75-85 degree air inside your home.  So the unit has to work much harder to cool down 120-170 degree air, rather than 75-85 degree air.  That reduces the lifespan of the system and increases your energy bills.  The system is also affected by the particles that bypassed the filter.  You don’t want to breathe the attic air full of dust and fiberglass, but it also hurts the unit.  The air from the attic gets blown over the coil to be cooled, and that causes the coil to sweat condensation.  Some of the dust and fiberglass particles from the attic air end up sticking to the wet coil, and it creates build up, sort of like a lint trap in a dryer.  Most manufacturers recommend that you clean the indoor coil every 2-3 years, and APS and Energy Star recommend cleaning it every 2-4 years, but with leakage, it needs to be cleaned more often.  Cleaning the coil is difficult and costly, so sealing the ductwork will help keep that coil cleaner.  When the coil gets residue and build up, it causes the motor to run harder in order to suck the air through that coil because it’s impacted with debris so the airflow is restricted.  When the motor runs harder, the amp draw increases, and so does your energy bill, not to mention the fact that it reduces the lifespan of the motor.  The dust and fiberglass particles that make it through the coil are pushed through the “supply” ducts and distributed in the air throughout your home.  Those particles also build up in both your “return” and “supply” ducts as well.  So if you have leakage in your “return” ductwork, it creates poor indoor air quality, an increase in dust throughout the home, an increase in your utility bills, and it reduces the efficiency and lifespan of the unit.

    There can also be leakage from the “supply” ductwork.  The leaks are usually also found at connections, as well as the seams and gaps inside the trunkline, distribution boxes, or the “supply” boxes that have the registers attached to them.  So after the air is sucked through the unit and cooled from the coil, it travels into the supply ductwork and some air just blows into the attic.  So besides cooling down your home, you’re also cooling down your attic, which is a waste of money.  

    The other issue is that the leakage from the supply ductwork will cause a vacuum effect on the home.  A five ton unit is made to suck in 2,000 cfm of air through the filter, and spit out 2,000 cfm through the registers.  So if that five ton system has 10% air leakage from the “supply” ducts, it’s sucking in 2,000 cfm, but it’s only blowing about 1,800 cfm into the home, and 200 cfm into the attic.  The unit still needs to suck in 2,000 cfm, and since it can’t get all of the air back that it spit out because 200 cfm went in the attic, it causes a vacuum in the home.  That vacuum pulls in warm outside air from doors and windows, and it also pulls in dusty and polluted air from behind electrical outlets and switches, as well as from any gaps at plumbing penetrations, light fixtures, ceiling fans, recessed can lights, and so on.  So once again, the leakage is affecting your indoor air quality.

HOW DO YOU REPAIR A LEAKY DUCT SYSTEM?

    Sealing air duct leaks in your duct system is usually an all day job, and in some cases it may take 2 or 3 days.  The total cost to make the necessary repairs depends on the size of the home, the type of ductwork used in the system, the amount of air leakage detected during the negative pressure test, and the overall condition of the duct system.  The cost can be as little as a few hundred dollars, or as high as several thousand dollars.  The good news is that both APS and SRP offer rebates to homeowners who have their duct system properly sealed by a certified contractor.  APS will refund up to $325.00 towards repairs and SRP will refund up to $400.00 towards repairs.  In many cases, customers who seal their duct system see a reduction in their utility bills and a return in their investment in just a few years.  Our home comfort specialists seal all of the supply and return ductwork in the attic at all seams, connections, and collars using a high temperature fiberglass reinforced elastomeric sealer.  We also seal any distribution boxes and trunklines at seams, collars, and end caps using the same sealer.  Our specialists then remove all supply registers and seal the ductwork from the inside at seams, joints, collars, and connections with a high temperature fiberglass reinforced elastomeric sealer.  Then we fill up any gaps in the drywall behind the registers using a silicone latex caulk, and reattach the registers.  They also seal inside all return boxes at seams and collars with the sealer, and fill up the gaps in drywall around the filter grills using a silicone latex caulk.  Some circumstances require additional sealing.  Duct systems that use return air platforms may require plating off areas using duct board or sheet metal and sealing over the plates.  Systems with fresh air return ductwork also usually require plating off areas and sealing over the capped section with sealer.  Sometimes leaks in the duct system are located at torn or deteriorated flex duct runs, or damaged hard duct runs or distribution boxes that cannot be properly sealed.  In those cases we replace or repair the ductwork as needed, and proceed with sealing the ductwork after making the repairs.

    Some homeowners have conditioned air loss from the shell of the home, referred to as the home envelope.  In some cases, customers request that Cool Touch make the necessary repairs to reduce the conditioned air loss as well as seal the duct system.  Our specialist can explain the benefits of sealing the home envelope after performing the negative pressure test, and inform you of the priority of the repairs, depending on the issues (allergies, asthma, COPD, dust, warm or cold rooms, energy consumption, etc.) each customer is concerned about the most.  There are a variety of repairs that can be made to the home to help reduce conditioned air loss, ranging from replacing leaky can lights with air tight can lights and sealing around plumbing pipe penetrations and installing weather stripping around door frames, to sealing inside electrical outlets and switches and sealing around speakers, sky lights, and light fixtures.  In some circumstances Cool Touch is unable to repair the issues we locate, such as replacing a leaky window.  In those cases, our specialist will inform you of the problem, and recommend a company that can perform the repairs.

    Once we have completed all of the necessary repairs to all of the leaky ductwork and conditioned air loss that we detected in your home, we perform the air duct leak test again to ensure that the duct system is properly sealed.  We guarantee that you will have a 60% or more improvement in air loss from the duct system after we have completed the sealing, and in many cases we have made a 70%, 80%, or even 90% improvement in the leakage.  We use high quality products when sealing your duct system, so the seal should last decades, and you will most likely never need to seal your ductwork again in the future.

Watch Out for these Air Conditioning Nightmares

Monday, June 16th, 2014

Living in Phoenix AZ has many luxuries. We get seven months of really awesome weather which makes up for the other five months of really intense heat. In Phoenix we have all major sports teams, all the big concerts, beautiful lakes and mountains, and if you want to ski in the winter you can drive two hours north and get radical, and when you’re done, you can drive back down to the valley back into seventy degree temps. The valley of the sun also offers some of the best fine dining in the country and we’re becoming more well known for our micro brews and wine.

Having many luxuries in our large city can also have it’s negatives. As mentioned above, our summers are brutal with temps reaching as high as 115 degrees. With so many people living out here and so many HVAC contractors to choose from, sometimes it’s a bit overwhelming to choose the most qualified and most honest and trustworthy.

Making sure our air conditioning units are running efficiently before the summer heat get’s here is very important. Having an a/c unit breakdown in the middle of 115 degree heat is no fun at all. You can put your family and pets in a lot of danger if your home does not having cool air flowing through it during these hot summer days. That’s why it’s so important to research the local air conditioning repair and installation companies in your town. Here’s at Cool Touch we have a perfect rating with the Phoenix Better Business Bureau and a perfect rating with YELP. Yelp is a very popular website that people use to check out the local services in their cities. You can get reviews from people who have used your services and usually if you come across a company profile like ours, you’re more than likely to call and use our services.

Back in May 2014 (this year), a woman in Florida needed to have an air conditioning repair technician come out to her home for what was supposed to be a quick fix of her stuck thermostat. When the a/c tech got to her home he tried to pull a fast one. Just because this was in Florida does not mean that Phoenix Arizona does not have these types of con artists. You need to do your due diligence and select only the local HVAC contractors that have good track records, even if that means paying a little more. Get it done right the first time and protect yourself from being swindled out of thousands of dollars.

Check out this video http://www.nbcmiami.com/news/local/Team-6-Investigation-AIr-Repair-Nightmares-258050741.html.

Remember, sometimes you may pay more for a service call, but usually if the company has a solid history, you’re not going to pay much more than the service call fee or for service work that may need to be done. I’d rather pay for those things than get hosed out of a few hundred or even thousands of dollars for equipment that I never even needed in the first place.

Ventilation Cleaning Offers Many Benefits

Tuesday, July 30th, 2013

During the summers here in Phoenix,AZ, most people spend between 60-90% of their time in-doors trying to keep cool. While spending time in the cool air conditioning, people are breathing air that is being filtered through their vents by their A/C system. Sometimes we forget to take the time and think about cleaning these vents and how important it is to breath in clean air.

Over time, dirt, dust, mold, debris and even animal droppings can begin to build up inside your home’s ventilation system. This in turn can contaminate the air from your heating or cooling system, spreading airborne particles throughout your living area. These pollutants can cause a number of health problems including aggravating allergy and asthma related symptoms. The best way to eliminate this problem is through ventilation cleaning.

Ventilation cleaning should be done on a regular basis as a part of regular maintenance. Signs that your ventilation system may be dirty include visible dirt or mold inside your ductwork, signs of pests or rodents living inside your ducts and unpleasant odors or excessive dust coming out of your heating registers.

By cleaning your vents, this could cut back on these health ailments:

– Sinus Congestion
– Asthma
– Sore Throats
– Coughing
– Fatigue
– Congestion
– Eye, Nose and Throat Irritation
– Nausea

Hiring a professional such as Cool Touch to clean and inspect the ductwork in your home can help improve indoor air quality, allowing you and your loved ones to breathe fresh, clean air. Make sure that the company you hire to handle the ventilation cleaning is fully licensed and insured. Consider asking for references from past clients, as well. The last thing you want is to hire a company that leaves your home a mess, or worse, causes damage to your ventilation system.

Along with cleaning your duct work, you may want to have the company clean and inspect the components of your heating and cooling system. Removing dirt and debris at the source is the best way to prevent it from being spread throughout your home. Blower fans, evaporator coils and air filters are all common trouble-spots for pollutants. Typically, if your vents are dirty enough to require cleaning, the rest of your system will benefit from cleaning as well.

Ventilation cleaning is an important part of making your home a comfortable, safe place to live. Taking the time to improve indoor air quality can help you and your loved ones breathe a little easier all year long.

Has Your Air Conditioner Quit on You in this Phoenix Heat?

Tuesday, July 2nd, 2013

Here in Phoenix AZ we are hitting triple digit heat already and air conditioners all over the valley are breaking down. In this heat the last thing you want to see go down is your A/C as it’s the only thing keeping all of us sane during these summer months.

When temperatures reach 105-117 degrees your air conditioning unit works much harder to keep your home cool then it does when temps are in the high 80’s and 90’s. If your unit quits on you, for your own safety, you need cool air as soon as possible.

In previous blog posts we’ve touched on things to do in the event you here your system acting out of the norm and what things might be causing certain issues. because of the recent heat wave Phoenix has been experiencing, and for the safety of all our fellow Phoenicians, we want to go over a new “what to do” checklist in the event your A/C system calls it quits on you.

A/C Unit Check List in the Event of Breakdown:

1. Check your thermostat making sure it is in the “AUTO” position. If it is not, move it to “AUTO” and see if your system turns on.

2. Is the thermostat indicating a low battery? If you have a low battery symbol or your screen is blank, replace the batteries to see if that was why your unit was not working.

3. Check your circuit breaker to make sure it has not been tripped.

4. Check your filter. Clean you and replace your air filters if necessary. A dirty air filter can clog the system.

5. Inspect your unit if it is completely off, blowing hot air from your vents or making suspicious noises. When calling for repair it is helpful for the technician to assist you as quickly and efficiently as possible.

6. Turn your unit to the off position and Call Cool Touch (623)584-3762 for emergency service.

7. While the technician is dispatched, use the following tricks to stay cool:

A. Close your blinds and turn off your lights.

B. Avoid using appliances that produce high levels of heat.

C. Do-It-Yourself Air Conditioner: Blow a fan over a metal bowl of ice.

D. Drink plenty of cold water to keep hydrated and your body cool

Why the Use of R-22 Refrigerant is Declining

Wednesday, June 26th, 2013

Older air conditioning units that still use R-22 refrigerant can develop leaks that slowly attack the earths ozone layer. It results in the creation of a dangerous by-product that is harmful to the environment and for this reason we’re seeing it’s decline within it’s manufacturing and is not used in newer a/c units.

R-22 is considered a greenhouse gas and newer a/c units now use ozone-friendly refrigerants rather than the dangerous R-22 refrigerant. In January 2010 the United States issued an order that all new HVAC system manufacturers could not use R-22 in their new equipment. Unfortunately many consumers have been sold older R-22 units and were told that they could find the refrigerant online. When an air conditioning company offers you free Freon or a cheaper repair on an AC unit that runs with R-22 be wary and politely decline. R-22 is being phased out and you should take that into consideration when you consider repairing an existing a/c unit. Consider what the cost will be to continue to run an AC unit that uses R-22, because in most cases, it will be more cost effective to buy a newer unit than it will to continually run an older one on R-22.

The Clean Air Act will not allow refrigerant to be released into the atmosphere during installation, service, or retirement of air conditioning equipment. R-22 will need to be caught and recycled in order to be reused, reclaimed, or destroyed. If you need to dispose of your R-22, please contact an A/C professional who knows what they’re doing to make sure that you do not break any laws or harm the environment. If you have an older AC unit and want to upgrade but have price concerns, consider the price of continual R-22 purchases versus a newer unit. Upgrading to a newer unit will come with less headaches and won’t require you to use cooling agents that carry rising costs due to the decline in their usage. Also, many A/C contractors offer financing options on new air conditioning units so you don’t have to worry about the cost all at once. And if they don’t offer financing, they will have other options that work with your budget in order to make it more convenient for you.

If you have any questions regarding your Phoenix air conditioner, or would like to determine whether it’s time to repair or replace your unit, please call the experts at Cool Touch. We will help you determine which option makes most sense for you. Cool Touch 623-584-3762!

Why the Cost of R-22 Refrigerant has Increased this Year

Tuesday, June 18th, 2013

The price of R-22 refrigerant has skyrocketed in the last few months. Due to government regulations to phase out the production of ozone depleting chemicals, like Freon, production has continued to decrease and has caused costs to skyrocket. R-22 refrigerant is four times more expensive than it was just six months ago and is expected to continue to increase significantly.

Due to this, A/C contractors have bought it at an alarming rate and supplies have declined greatly. This has forced some vendors across the country to limit the amount of R-22 contractors can purchase in a month.

As the cost of R-22 rises, the cost of the new replacement Freon, R410a continues to drop. It is simple economics of supply and demand.

Federal regulations have called for a 90% reduction of production of R-22 by 2015 and to be completely obsolete by 2020. What this means to consumers is outrages freon related repair costs and eventually no choice but to replace their HVAC equipment.

Most air conditioners manufactured before 2010 uses the old R-22 refrigerant.
While a R-410a unit can just as easily develop a leak as an R-22 unit can, from vibration, rust, stress cracks, etc, the cost to replace R-410a is a fraction of R-22.

As a home owner you need to keep a few things in mind. If you are in the market for an air conditioner do not let any contractor convince you that an R-22 unit is a good idea. They get around the law by shipping them with no refrigerant in them and classify them as a “part”. These “dry charged” units may be cheaper initially, but in a very short time frame you will be forced to upgrade to an R-410a system.
If your unit is 11 years old or older, you should start planning for an upgraded system. You can decide when to replace your system or your system will decide for you by breaking down when you least expect it!

If you have a slow leak in an R-22 system and have to add Freon every year or sooner, consider the cost of continuing to add Freon that is climbing in price. That money could be going towards a new high efficiency unit that will start saving you money on your utility bills the day it’s installed.

Should you need help deciding if it’s time to replace your current A/C unit and want an honest opinion, you can count on Cool Touch to assist you. Our experienced, professionally trained technicians will be able to determine which choice makes sense for you and your home and will go over all options with you. Call us today 623-584-3762.

Diagnose Your AC Unit

Thursday, May 23rd, 2013

Here are instructions on how to troubleshoot your air conditioning system. To diagnose your air conditioner or HVAC system in an ordered, methodical and proven way to get the answers you need, you have to take some time, get educated, and this will save you a lot of money. Commission based A/C techs love nothing more than an ignorant consumer. They can sell you anything from a surge protector to float switch, even up to a new unit for a simple run capacitor or burnt wire.

Experienced HVAC companies will take the time to explain things and provide the best service possible with honesty and integrity.

First question in the diagnosis:

1) Is air blowing from the registers? Yes or no

If yes, then go through this check list:

A) Is the condenser fan motor and compressor also operating?
B) If all motors are operating and you are getting warm to ambient air than probably a refrigerant issue.
C) That can come in the form of low refrigerant, slow leaks, big leaks,
leaking reversing valve if the heat pump is clogged.
D) If air is warm at registers check condenser fan motor and compressor.
E) Does the condenser fan blade turn freely with a long-handled screwdriver? or is it binding up?
– binding up usually means it is seized up
– test the run cap first before replacing the condenser fan motor
F) Compressor may or may not start back up if run cap on fan motor is popped
– it has an internal overload protection that must reset at appx 115 degrees to operate again.

2) Is there air at the registers?
A) It may be cool but very low airflow
– dirty evap coil
– leak in ductwork
– very dirty filter
– if this is the case the compressor and outdoor fan motor will probably trip on overload

Referring back to question #1 above, if the answer is No then review this check list:

A) when you operate the thermostat does any other modes work (fan to on or heat)?
B) Is there ice on the big copper pipe (suction line) when the outdoor unit (compressor, condenser fan motor) comes on?
C) If yes than shut off the system.
D) If No and all other modes are shut down, this maybe an issue with:
– control problem
– change batteries in t-stat
– float switch backed up
– 5amp fuse in air handler (there is a reason it popped – gotta find out why)
– transformer blew (it happens)
– bad wiring
– main breaker for whole unit

This is just a short list to help get you going and to provide steps in the proper way to diagnose your air conditioner. If you feel you need an expert please don’t hesitate to call one of our experienced techs at Cool Touch to come out and give you a hand. Choosing the right AC company to help you with a complex problem is very important so feel free to browse our customer reviews section.
