Air Duct Maintenance Program

Air Duct Maintenance Program

Whether or not you decide to have the air ducts in your home cleaned, committing to a good preventive maintenance program is essential to minimize duct contamination.

To prevent dirt from entering the system:

Use the highest efficiency air filter recommended by the manufacturer of your heating and cooling system. Change filters regularly.
If your filters become clogged, change them more frequently. Air duct Filters San Antonio
Be sure you do not have any missing filters and that air cannot bypass filters through gaps around the filter holder.
When having your heating and cooling system maintained or checked for other reasons, be sure to ask the service provider to clean cooling coils and drain pans.
During construction or renovation work that produces dust in your home, seal off supply and return registers and do not operate the heating and cooling system until after cleaning up the dust.
Remove dust and vacuum your home regularly. (Use a high efficiency vacuum (HEPA) cleaner or the highest efficiency filter bags your vacuum cleaner can take. Vacuuming can increase the amount of dust in the air during and after vacuuming as well as in your ducts).
If your heating system includes in-duct humidification equipment, be sure to operate and maintain the humidifier strictly as recommended by the manufacturer.

To prevent ducts from becoming wet:

Moisture should not be present in ducts. Controlling moisture is the most effective way to prevent biological growth in air ducts.

Moisture can enter the duct system through leaks or if the system has been improperly installed or serviced. Research suggests that condensation (which occurs when a surface temperature is lower than the dew point temperature of the surrounding air) on or near cooling coils of air conditioning units is a major factor in moisture contamination of the system. The presence of condensation or high relative humidity is an important indicator of the potential for mold growth on any type of duct. Controlling moisture can often be difficult, but here are some steps you can take:

Promptly and properly repair any leaks or water damage.

Pay particular attention to cooling coils, which are designed to remove water from the air and can be a major source of moisture contamination of the system that can lead to mold growth. Make sure the condensate pan drains properly. The presence of substantial standing water and/or debris indicates a problem requiring immediate attention. Check any insulation near cooling coils for wet spots. Make sure ducts are properly sealed and insulated in all non-air-conditioned spaces (e.g., attics and crawl spaces). This will help to prevent moisture due to condensation from entering the system and is important to make the system work as intended. To prevent water condensation, the heating and cooling system must be properly insulated.

If there is any indication of water damage, you may need to call us immediately before mold growth becomes present. In this situation timing is of the essence, since mold can form within hours of the water damaged area. duct-allergens-

AC fans are not blowing

Here is what you should do if your AC fans are not blowing

AC fans not blowing? Don’t worry. There are times when machines stop working and there is a particular problem which hinders its operation. Same is the case with the AC. If there is any problem with your air conditioning system, the problem is likely to lie within the machine. Whether it be something associated with the settings, the machine itself or the outdoor compressors, you will have to make adjustments and AC repair to make your device work. In case that you find your AC fans are not blowing the way they are meant to be, here are some causes and solutions to this problem. Air Conditioning RepairSee more information here @

Locating the unit fan

The first thing that you need to do is to locate the fan unit of your AC. It is a blower that helps in moving the outdoor air through condensing coil and is present in the outdoor compressor or condenser unit. As the outdoor air goes through condenser coil, it sends the heat to outdoor air and let the high-pressure refrigerant which is present in the condensing coil to convert it from a back to its liquid state.
You can see the condenser fan inside the outdoor compressor unit. Like any other fan, it has the motor and blades that help in keeping it running. Note that the design of the fan may vary from the compressor to compressor and AC system to AC system. It is not necessary that each AC fan unit will have an identical design.
In case that you reach out to the fan and see it is running, you will be able to spot the blades moving at high speed. It is typically around 1725 rpm and standing in front of it; you will be able to feel the air blowing out of the unit.
There are times when you have to be careful as the fan unit is not operational due to the burned out compressor. This will make the compressor shut down on its own or else the fan unit will be ruined due to overpressure and excessive temperature.
How does it work?

Now, coming towards the fact that how an AC fan unit works in moving heat from inside to outside, there is a condensing coil making it all possible. It receives a refrigerant gas which is at a very high pressure and is coming from the compressor. This cools the refrigerant gas back to the liquid state. The refrigerant enters the outdoor condensing coil as soon as it departs from the compressor. The pressure is around 100psi with a temperature of somewhere around 95 degrees F. The pressure at which gas is entering may vary depending on the factors such as the type of refrigerant, appropriate temperature, compressor details and much more.

Then the outdoor cooling fan comes into the play as it passes the outdoor air across the condenser. As it goes through the condenser, it becomes low in concern with the temperature, and the high-temperature refrigerant turns back into liquid form.
It is a complete and a bit complex process that takes place within the compressor and condenser. The outdoor fan unit plays a critical role in making this all happen appropriately.

What if the fan is not working?

If the condenser fan is not starting, here are certain things that you should take a look at to make it work.
First of all, check that the power supply is available to the outdoor unit. If the power is not available, the unit will certainly not work. And if the power is given but at a varying voltage, it will harm your AC. Therefore, it is necessary to give the machine a steady power supply in order to make it work.
After that, ensure that you have your AC set to thermostat mode that is calling for the fans to work. Moreover, make sure that motor is starting and running normally. In case that the motor runs normally, but the fans are not working, the fault may be laying in your motor as it can be either overheated or damaged.
There are times when motor works if you give it a push. In case that the fan is stationary and you are looking to try it, avoid using your hand or else there may be a risk of losing it. Use a wooden stick for the work and if it starts with a push, then installing a hard run capacitor for blower fan may be able to do the trick for fan not blowing
Another case is when you have a condenser fan won’t work while the power is turned on. However, as soon as you turn off the power and give it a spin, the blades move easily. This means that the problem might be present in the motor shaft bearing as they are worn. You can detect this by pulling the shaft in and out of the motor.
In short, if your condenser fan unit is not working at all, look for the power supply to fan and ensure that it is steady. Check for the controls of your AC and make it certain that you have it set to call for cooling (in other words for the heat pump operation). Furthermore, take a look at the wires and check for loose or disconnected wires. Moreover, the motor might be frozen, and in that case, you won’t be able to even move it manually when it power is off. And if you can move motor when the power is off by a simple push, go for installing the hard start capacitor for the blower fan.
Final words
So, these are certain things that you can do if your AC fans not blowing. In case you are having difficulty in dealing with it, call the professionals. Dealing with it is crucial and if the blades start spinning while you are in for the investigation, there is a real danger of any serious cut or injury.
