How to Install Retrofit Windows on Stucco

How to Install Retrofit Windows on Stucco

Installing retrofit windows on the stucco wall is not too difficult. The challenge is to ensure that it doesn’t leak and that it looks clean and polished. If you are planning to install a new window by yourself.

Here are the steps that you must follow:

1. Assess the existing window

Identify if the window is made of wood, steel, or aluminum. The existing frame of the window will be intact while the interior portion of it will be disassembled or detached. This is to avoid dismantling the weather-resistant barrier or the wall which is responsible for protecting against moisture entering the home or property. 

Since you are installing a retrofit window on a stucco wall, you should use an appropriate sealant that is compatible with the substrates. For example, Siloxa-Tek 8500 is an excellent sealant for stucco. It is also a salt repellent sealer. So if you reside in a tropical state with salts in the air, this sealer will prevent cracking, spalling, and pitting. 

2. Measure the opening

From the existing window, take off the sash members and metal rails to make sure that you are measuring the narrowest point in your window. This is the daylight opening measurement. Get the daylight opening width measurement at three angles – top, middle, and bottom. Afterward, get the height measurement in three angles – left, middle, and right. When you have the narrowest width and height measurements, subtract ¼ from each to get the “net frame size” for ordering. 

Once the new retrofit window is installed, its flush fin will lay perfectly flat against the existing window frame and stucco. Check closely if there’s any part that extends past the stucco or siding. If there’s any, cut way such excess parts. Hinges and drip legs before installing. 

3. Inspect the window prior installation

If there is any damage to the window frame joining seals, it must be repaired. The sill track should be able to hold water without leaking to the interior for at least 15 minutes. After the inspection, disassemble the existing window by removing the vent panel, center post, fixed panel, and any other components that will interfere with the installation. Just keep the existing frame intact. 

4. Polish the exterior surface of the wall

Using a stiff bristle or brush, putty knife, scrape or grind any rough texture on the exterior surface where the flush fin of the new window will be placed. This leaves a smooth surface for installation. Don’t forget to also remove dirt from the sill track. 

5. Test the retrofit window if it fits the size of the opening       

Before caulking, test fit the retrofit window size if the frame matches flush against the wall or as close as possible. If there’s a gap found, try to lessen it as much as possible by using additional blocking for sill support. You can also trim the flush fin if a narrower width is needed.

6. Pre-drill pilot holes into the interior channel of the new frame 

Avoid drilling into the sills. Holes must be no more than 18” apart, on center, with corner holes approximately around 6” from the end. Make sure that nothing interferes with the sash operation.

7. Put a continuous bead of sealant along the exterior perimeter of the window

Run the sealant along the exterior of the window where the flush fin connects with the wall. Leave a 2” allowance at each corner at the sill to allow any moisture to evaporate. 

8. Insert the new retrofit window into the opening

Make sure that the retrofit window is level and precise by shimming the frame from the interior. 

Install shims at fastener points where it is possible. Using a pan head screw, secure the window in place. You can begin from the upper jamb corners. Go over the level and shim if needed. In the opposite jamb, place an additional screw and recheck for level. If the frame is properly level, attach the rest of the screws.

9. Run a bead of sealant around the exterior edge of the flush fin

Once the window is secured, finish with sealant sound the exteriors of the flush fin. Wipe off any excess for a clean look. Meanwhile, from the interior, use a backer rod or insulation material to fill the gap between the old and the new frames. You can hide the void with flat interior trim or any of your choice. Run a bead of sealant along the edge of trim for a clean, polished look.

Why‌ ‌My‌ ‌AC‌ ‌Unit‌ ‌Makes‌ ‌Loud‌ ‌Noise‌ ‌When‌ ‌Starting?‌

Noise AC

It might be quite a shock if you hear your air-conditioner make some noise. This is unusual since technological advancements today made sure that they have sound-dampening technologies. If clanking, buzzing, banging, or other noises are present, then this might be a sign of trouble!

Probable Source of Noise :

Debris Inside the Unit

 A quick fix is all this needs, as long as the debris can be taken out safely. You will quickly identify this if you hear a low buzzing or humming noise coming out of your unit. 


When too much pressure is building up within the compressor, it produces a loud whistling noise. Contact a professional right away for this is dangerous. Compressors are tedious to repair, so you will have to replace it most of the time.

Air Filter

 A filter that does not fit correctly may produce some hissing noise. Relatively, this is easy to fix, for you only have to readjust it.

Air Handler

 An electrical problem is the issue when the air handler makes some buzzing noise. Some examples are loose wiring, broken capacitor, arcing, or others. This is best left to the hands of your technician.


 In some instances, the fan of your air-conditioner might loosen and hit other parts inside the unit. It will also produce clicking noises if something is obstructing it. If left unchecked, this might damage the other parts stopping its motion. 

The fan may also produce noise when its blades are bent or damaged, or they are dirty.

Fan Motor Bearings

 Screeching noises are created if the fan motor bearings are failing, and you might require replacing it. 

Fan Belt

Due to varying temperatures, the fan belt contracts and expands, making it worn over time. It will make squealing noises when it becomes misaligned. You have to replace it or it will break and leave you with no air.

Condensate Drain

 If your condensate drain line does not have a proper trap, it might make some bubbling noises. You can check it yourself, and it would not be hard to fix.

Refrigerant Leak

Contact your HVAC contractor hurriedly if your unit makes loud, screaming, noises. Turn your air-conditioner off once you hear it because a refrigerant leak is what it means, and it is very unsafe. 


 Your ductwork will respond to the change in temperature as your air-conditioner turns on or off; especially if it is metal. This won’t damage your unit, but you can use insulation if you want to reduce the sound.

Isolation Feet

 You might hear a buzzing noise when the isolation feet become worn or cracks. This is because the compressor gets tilted and unbalanced. 


 A good measure is to turn your unit off until proper solutions are done. If what you hear from your air-conditioner is too unsettling, and you are afraid to solve this by yourself, call a professional for support. They are ready to offer us help, after all!

How to Repair AC Duct Work

Repair AC Duct Work

HVAC is very important to keep the comfort of many people especially in a household, office, hotel, and others, so it can give you a headache when it seems to not work properly. Some tips are here to help you identify what kind of problem you are dealing with in your HVAC system, and to help you solve it.

Troubles You Might Be Having with Your System

  • Inconsistency

If you feel like some places within your area are much cooler or much warmer than the rest, this might be the first sign that something is wrong within your duct system. A leak might be a cause or disconnected pipes.

  • Whistling Noises

If you hear some strange noises from some parts of your house where the duct runs through, then that is some kind of hint of a weak airflow or pressure imbalance.

  • Poor Air Flow

Your air duct should blow air in vents and when you notice that one vent, in particular, is not blowing air while the others are, it is an indication of an issue with the ductwork. This might be because of blocked air vents or clogged filters, poorly sized ducts as well as leaks.

What You Can Do

If you cannot identify the problem yourself, it is best to call a professional or contact your most trusted HVAC contractor. It will always help to have someone who knows more than you do. One problem you might have trouble solving yourself is if your duct is too small (restricts airflow) or too large (reduces airflow). This might require you to need a technician to replace your air duct. However, if you can find the problem and that you are confident that you can solve it yourself, then take care and make sure you do it properly.

Before doing anything, make sure the system is turned off. If you find some kind of obstruction that compromises airflow, for example, a cabinet moved in front of an air vent, simply move it away. If you found out that your AC filters are clogged, you can clean it or change it.

If you find leaks or tears in the ducts, pipes, or poorly connected joints, you can use special foil tapes to seal them up. You can also use fiberglass mesh tape to reinforce it then use duct mastic with it. Make sure that the materials and adhesives you use are suitable for ductwork to avoid further mess or damage.

After sealing up the leaks or removing the obstructive objects from your duct system, inspect the ductwork again. Turn on your AC and observe if the problems earlier are still present or if the noise is gone and the cooling effect of your system seems consistent, then that is how you know you did a good job.

The Best Way to Avoid Problems in the Future

The best thing to do is to have your AC ducts maintained. You can apply for annual services by your HVAC contractor or you can have cleaning services. Inspection and diagnostics are also good for your duct system.

You always have to take care of your system if you want to not spend too much on repair costs but you should not hesitate to fix problems as soon as possible to avoid further problems in your HVAC system!


How to Repair a Window Air Conditioner

Repair window aircon

Every summer one of the basic needs of a person to survive the heat, apart from water for bathing and drinking, is an air conditioner. Especially when the weather is really hot and people, especially the elderly to cope with the hot weather because they are prone to hypertension, heatstroke, and dehydration. So it is best to keep them in cold places such as air-conditioned rooms to prevent them from being sick.

Before the arrival of other types of air conditioners, there is a window air conditioner or also known as a room air conditioner as it is best used in small spaces or rooms. It is the simplest type of aircon in which the evaporator emitting cold is inside the room and the condenser emitting heat faces the outside of the room.

But what do you do when your air conditioner suddenly breaks down in the middle of extremely hot weather and you can’t find someone that can repair it?

Don’t worry because you can self-check and repair your air conditioner’s common damage using the tips I will give.

But first, I will point to its parts and functions that are causing common air conditioner problems.

  1. Condenser fan — release the hot air from the condenser coil outside the room.
  2. Condenser coil — converts the hot air into cool air.
  3. Compressor — controls the movement of air and the coolant material inside the air conditioner.
  4. Thermostat — controls the air and room temperature.
  5. Fan — release air from the air conditioner out of the room.
  6. Evaporator coil — used to cool your room.
  7. Face panel — contains the air filtration system of the air conditioner.

Once you know what parts are often faulty in your air conditioner, let’s go over the common problems that you can count on in your air conditioner.

The air conditioner does not blow cool air

This is one of the problems many aircon users have because they have purchased this device to provide cold air so what is the use of it if it does not release cold air, right? The most common reason why your aircon cannot produce cold air due to its dirty air filter or damaged condenser coil. When the condenser coil is broken, your aircon cannot convert the hot air into cold air so your air con will not be able to release cold air. When this happens, you should clean your air filter first as it may not allow the cold air to come out because it is dirty. When you have cleaned, and the air is still hot, check your condenser coil located on the exterior part of the unit. When the condenser coil is broken, you have no choice but to replace it, but if the fins are just bent and just simply use a fin comb to straighten it.

The air coming from your air conditioner has a stinky smell

it is normal to have an inside scent when you have food inside your room because the air is just circulating inside but what if there is no food in the room but there’s still a stinking odor coming from your aircon? Often the air can have a bad odor due to the accumulated moisture inside the air con. Moisture can cause odor-causing bacteria like molds that cause bad odors. To solve the problem, always clean your aircon filter and compressor to ensure that there is no accumulated moisture inside the aircon that causes the odor of its air.

Your air conditioner doesn’t turn on 

Are you also one of those that have a mini heart attack when your air con doesn’t turn on even when it’s plugged into the power source, don’t worry because it doesn’t mean that it’s broken. Check by unplugging the cord and installing it again. If the air con doesn’t turn on after checking, look for other possible problems. Check your breaker and fuse that regulates the electric current. Reset the breaker and try to open the air con if it’s not checked for the fuse. The fuse regulates the circuit’s amperage rating. When the amperage rating is lower or higher, the air con will not work so when you find out the fuse is broken, replace it immediately.

Your air conditioner has a weird and loud noise

When your aircon is louder or noisy, it doesn’t mean that there is a phantom or a ghost in your home. It can be the aircon fan belt may be loose or broken. When the fan belt is loose, you can simply attach it more neatly and tighter to the unit, but if it is damaged, immediately replace it for the better performance of your aircon.

Water leaks on the front panel 

This is one of the annoying problems of aircon users because the moisture releases on the face panel instead of on the back of the unit. Supposed to be a metal pan in the bottom of your air con will drain the water out of the hose behind the air con for moisture to escape, but what if that doesn’t happen? Make sure that the aircon level is properly fitted to the hole in for it in your wall to ensure that the drain hose is securely attached downward to the rear of the unit to prevent moisture accumulation inside the metal pan and that can cause moisture exit in the front panel.


HVAC Testing Adjusting Balancing: Your Air Conditioning System’s Functions

HVAC System

A lot of people think of their HVAC system as a type of machine, but it isn’t. The mechanical system is the one that put out heat, and the energy that it produces is required to keep the building’s occupants comfortable. However, when you add air conditioning to the equation, it is actually the process of adjusting the temperature of a room so that your air stays at a comfortable level.

Air conditioner unit that works to pull air from the outside of the building where it has been heated and redirects it into a space inside of the building. It usually requires a fan that pushes air through a system that filters and cools the air that is pulled from the outside. Once the air enters the room, it is distributed in many different ways.

As the air enters the room, some is distributed by the air flow and comes out of the doors, while others are circulated through the rooms. This process is called dehumidification. The exact proportions of each of these are affected by the air conditioning system because the heating and cooling elements of the system work together.

When you have an air conditioner on the outside of the building, the air from the outside cannot be released because of the pressure that the air can exert on the systems that are inside the building. If the air is flowing through the system efficiently, the refrigerant lines that carry the cool air to the unit are not damaged. Instead, they produce more cool air to bring into the area that is cooling the air to be circulated. This is known as air conditioning air balancing.

For a good working relationship between the air conditioning and the heating and cooling units of a building, they need to be set at the same temperature or they will produce too much heat. This can cause problems for the heating and cooling units that operate at different temperatures. As the HVAC Testing Adjusting Balancing process begins, the air is tested to make sure that it is at a comfortable temperature before it gets to the room.

Once the system is set to that level, the systems that distribute the heat and cool air will begin to adjust to the new environment. The heating and cooling units will adjust their own temperature, and then the systems will begin to adjust as well. This means that everything will work as efficiently as possible to provide the most comfort and circulation to the occupants of the room.

Although the air-conditioner unit will be at a comfortable temperature, the HVAC Testing Adjusting Balancing process is still necessary because the air that is entering the building needs to have a specific temperature that is uniform throughout the entire room. Each unit has its own requirements in regards to temperature, so the temperature needs to be consistent throughout the building. Having a cool temperature outside of the building and a hot temperature inside will create a problem that must be solved before a normal room temperature can be attained.

These temperatures are established and maintained with the help of the HVAC Testing Adjusting Balancing process. It will also help to avoid problems that can occur when the system isn’t operating as efficiently as it should. For example, if you are using a cooling system and the HVAC Testing Adjusting Balancing process allows it to stay a cool temperature, but the temperatures outside of the building change, there will be problems. This is another great reason why you want to make sure that your HVAC System is operating properly.

The HVAC Testing Adjusting Balancing process is designed to test how well your air conditioning system works and how it will perform if you start to operate it with heat and cool, as well as make sure that it is balanced. If you find that it is overheating while it is cooling down, you can solve this problem by adjusting the heating and cooling units to a cooler temperature. This means that your air conditioner will be operating at a good temperature, but not heating up to a high level.

You might also see that the air conditioner is generating more energy than you thought that it was capable of. With the air conditioner operating at a different temperature than the air in the room, the air conditioner will not get the amount of air conditioning that it should. without adjusting the system’s settings. There are a number of other reasons that you may need to adjust your HVAC System so that it runs more efficiently.
