Water in Ductwork, NOT TODAY!

Have you heard the following things listed OVER & OVER again in regards to your HVAC unit?

“No one wants any sort of strain on their HVAC unit. Strain that could cause many problems that are an extra cost to you. Such as:

-Higher energy bill
-Frequent maintenance on your HVAC unit
-HVAC replacement

There are many ways to keep your HVAC unit stress free. Below are just a few basic steps you can take to keep your HVAC system stress free. Very easy stuff, and they each only take a few moments of your time.

-Keep vents clear
-Keep those coils clean
-Change out the air filters regularly”

BUT, one thing that goes unmentioned quite often is the ductwork. Of course it would. Out of sight, out of mind, right?

Did you know, ductwork carries the warmth in the winter and holds the cool air in the summer. Without proper ductwork insulation, the temperature of the air being carried could be lost while transferring from the HVAC unit to the vents in your home. Ductwork can also play a major role in your energy bill. Even the Department of Energy claims so.

So, you see how important ductwork is. What if just a little bit of water entered your ductwork from the HVAC system? It’s just a little water. No biggie, right? Actually, YES! Even the smallest water droplet is a huge deal! To name a few, it can cause the following:

-Rust out metal ductwork
-Breeding ground for mold, mildew, and bacteria
-Decrease Indoor Air Quality greatly
-Water damage
-Degradation & De-lamination

Although, water in the ductwork can cause many problems. Your health alone should be enough reason to want to get your ductwork checked out. Exposure to mold can lead to allergies, infections, rashes, even alzheimer’s. The list just goes on and on.

When water gets in the insulation in your ductwork, those water droplets fly through your airstream. These water droplets create a breeding ground for mold & mildew. Water droplets will wreak havoc on the insulation in the ductwork causing degradation & de-lamination. Not only would this be tearing your insulation apart to later be replaced (more bucks from your pocket) but that delaminated insulation would be freely roaming the air in your home (remember you & your family are breathing this).

Why worry about water in your ductwork causing this step ladder of issues when there is a solution?

For the new home-owner, why not be preventative & go ahead and protect yourself?

Ductile is a coating that protects the HVAC ductwork from degradation and insulation de-lamination. Ductile locks down fiberglass particles that would enter the air stream. Hallelujah!
No stress of your insulation breaking down & no worries about your health. Did you hear that, NO STRESS!

Guest Blog: How to Fix Common Problems with Your Air Conditioner

Air conditioning needs proper maintenance and checkups, even if there is nothing broken. However, we cannot expect that the unit will be working flawlessly all through its economic lifespan. Of course, there are times that your AC unit will stop working one day and it might just be a common problem that you can just fix yourself (read Replacing HVAC vs. Refurbishing HVAC). So it is better that you understand all the common problems in an AC and how to be able to fix them.

Common Problems


AC will not turn on


1. The thermostat is broken – a broken thermostat can cause the whole unit to not function properly. Make sure that you have a reliable and a programmable thermostat. Do a weekly check-up if possible if your thermostat is broken.

2. Circuit Breakers are tripped – If your unit’s circuit breakers are malfunctioning or have tripped, do not just reset the circuit breaker right away. Try to analyze the problem first as to what caused the tripping of the breakers. If it continues to trip again, then have a professional take care of it.

3. Vents are clogged – The outer part of the AC unit is sensitive to nature and often times can be clogged up caused either by grasses, dirt, debris, or other vegetations. The best thing is to get an AC cover. If there are debris stuck in the vents, be sure to call some professional help because it can damage the AC’s capacitor.


Strange Noises in the AC

Oftentimes, if an AC is not performing right, there are noises that you hear. A noise can indicate that there might be a problem in your AC unit.

1. Rattling Sounds – if the AC is rattling or vibrating, then it is more likely that the AC was improperly installed. This is where you need some help with a professional.

2. Squealing noise – Older AC units, they use belts rather than motors and can cause a squealing sound when a belt that is connected to the blower has slipped. What you need to do is turn off your AC and seek a professional’s help.


• AC is Running but it is Not Cooling


This is the most common problem in all households. Check if the AC works on the inside or outside, and in order to do that, here is the check list to help you assess the issue.

o Check the outside or inside unit and hold your hand nearby to feel if there is air coming out or if there is heat leaving.

o Check the two refrigerant lines where you should see large and small lines. Do not touch the small line as that is hot. The large line is usually cold and might have some condensation.

o If the large line is showing that it is frosted, then it means that the air flow across coils from the inside unit is not functioning properly or the refrigerant is low. So the next thing you need to do is turn off the thermostat and then turn the fan on (from auto to on at all times). Let the fan run continuously and shut the compressor off.

o Let the fan run, for 30 minutes and see if there are improvements, especially if the air flows are running through the vents.

o Try to also check the air filters if they are dirty and if dirty, needs to be replaced.

o If it is a refrigerant problem or compressor problem, you will be able to tell if the large line is not cool and the small line is not warm. Call a professional for help.

• Power Wire Problems


This usually happens when you constantly turn your AC on and offthis can mess up the AC’s compressor and the fan controls. The wires can cause to corrode through the continuous wear and tear. Better to have a professional do an evaluation of your wires to prevent any further damage to your AC unit.


• The thermostat is not Picking Up the Correct Temperature


Just adjust the sensor by bending the wire that holds it in place carefully.


Drainage Problems

A humid temperature can cause clogging in the condensation drainage. Best to check the drain for any clogging problems; if you find out that there is any clogging, then mount the drain at a level.


• AC’s Outside Fan is not Working


This is usually caused by overheating in the compressor.


• AC is not Running


The unit might not be receiving any power, so the best thing to do is check to make sure all wires and cords are plugged in properly.


• Frozen Coil


This is usually caused by air filters being dirty, blocked air in the ducts or has a low Freon. This case, you will need to call a repair man or maintenance guy.

So if you are facing these problems with your AC – may it be an evaporative air conditioning unit or gas ducted AC, you know what to do. May this serve as a guide, but it is best to seek help from the experts if you are not sure about fixing the problems yourself.

Technical Corner: Handling The Unknowable

It is well understood that air handlers are essentially an enclosure for heat transfer coils and system fans and filters.  It is also a fact that removing and replacement of these units is expensive – quite expensive.

Often, owners wisely elect to refurbish the AHU instead of replacing the unit.  This saves major dollars in almost all cases.  It is almost surprising to see a corroded AHU almost literally falling apart be turned into a usable piece of equipment with a considerable renewed life span, often greater than 15 years.

While the owner might do the refurbishment himself, he may also elect to have an outside contractor perform the refurbishment if he has no staff or limited maintenance support staff available.

Older units gradually lose their galvanizing (the zinc coating over the sheet steel), particular in those areas where there is a lot of water – like the condensate water collection pan, and the coil structural supports.   When corrosion occurs in these places, metal thins of course, and small perforations occur through the metal.  These holes are normally small, the size of pinheads.

They are exceeding difficult to see, if they can be seen at all, when the water is drained from the condensate pans.  This is because the pans sit on concrete and there is no backlight to see these small holes are there.  Larger ones yes, but the smaller ones no.

Because Pancrete was engineered to a water-like consistency to help it flow all over the pan surfaces and under the coils, it will also, like water, tend to seep out through pinholes.  Thus, one can  pour in Pancrete and have it slowly drain out of the pinholes, depending upon the size of the pinhole and the number of them.

Service technicians can hardly be blamed for not seeing the pinholes in the first place – they may be very small and unnoticeable, or the crew  may be working in the middle of the night to do the refurbishment, be in a hurry to finish and not notice them.

A significant method to solve these possible problems is to use the Panhole Filler.  It is designed to be an underlayment for Pancrete that Pancrete will seamlessly adhere to.   The new Panhole Filler will fill holes up to 50 mils in diameter so as to prevent Pancrete from running out of these small, unseen pinholes in the metal.

The Filler is rolled onto the horizontal surfaces first, let to set up, and then Pancrete is poured as usual.  Use of the Filler prevents any surprises so the job goes A to B.   Outside of wasting Pancrete that has leaked through, it invariably is an embarrassment to the refurbishing staff.

Call CRT customer service to learn more about how the new Panhole Filler can help you compete jobs faster with no surprises.
