Is Window Condensation a Problem

What Is Condensation?

Is your Window glass “sweating” in the winter . Is water beading or ice forming on the inside surface of your windows?

Don’t be too quick to blame the windows! There’s a good chance that what you are seeing is condensation,
a sign that there is excess humidity in your home. Humidity – water vapor mixed with air – is drawn to
the coolest surfaces, such as your window. Condensation problems arise because air can hold only a limited
amount of water vapor at any given temperature. Cold air can hold less water than warm air.

Cool air cannot hold as much moisture as warm air, so windows and doors often collect this moisture and make it visible.

Sources of moisture

The principal sources of water vapor in today’s homes vary with lifestyles but the following is just a small list
of normal daily activities and the water vapor they introduce per day.

Cooking (three meals a day) 3-4 lbs
Dishwashing 1-2 lbs
Shower or Bath 1-2 lbs
Weekly Laundry 30 lbs
Occupancy (family of four) 12 – 15 lbs


What Can we do to reduce moisture in our  home

More and more of us are living in “air tight” homes, they are more economical to heat and cool and easier to keep clean but we
have created another problem and that is lack of air exchange and moisture traps. Since the moisture levels are not able to
escape we must take steps to reduce humidity in our home

  1. Reduce Moisture Sources
  • Stop or severely limit the use of humidifiers, or adjust them to the appropriate setting
  • Run a dehumidifier if needed.
  • Limit plants, aquariums, and pets. If you have a lot of  plants, don’t overwater them and you should
    put them in a sunny area.
  • Make sure that your clothes dryer is properly vented outside.
  • Malfunctioning gas appliances can deliver excessive water vapor into the air along with more dangerous
    contaminants. So have your appliances check regularly
  • Eliminate plumbing leaks.
  • Don’t air-dry clothes indoors.
  1. Increase Ventilation
  • Open your windows everyday  for a few minutes , particularly after steam-producing activities
    such as showering/bathing, laundry, and cooking. You will only loose a small amount of heat
  • Run kitchen, bathroom, and other fans longer and more often.
  • Improve or add a ventilation system in your home through attic, roof and soffit venting.
  • Open blinds and drapes. Heavy window coverings restrict the flow of warm air over the interior glass surface.
  • Operate ceiling fans to improve air circulation in your home


In most cases you can reduce window condensation by addressing  high humidity and condensation through
reducing the amount of humidity generated in your home. By providing your home with the proper level of humidity,
you are on your way to providing  healthier  Indoor Air Quality in your home.

Should you clean your ductwork after a renovation

Should you invest your money in Air Duct Cleaning after completing your home renovation or home remodeling project? Customers frequently ask this question after a renovation project (bathroom remodel, kitchen remodel, finishing the basement ) or any other extensive remodel project where a lot of dust has been created. Power Vac always recommends it, because it can only help improve the home’s air quality, especially after a large renovation project that can create a lot of construction dust. If you suffer from allergies, it should be strongly considered
If you are moving into a newly constructed house, and have doubts about the diligence of the construction crew, duct cleaning can be useful. Drywall dust, fiberglass pieces, and sawdust have no place in ducts. Duct cleaning will also catch the odd occurrence where lunch bags or soft drink cans have fallen or been swept into the  duct system. For similar reasons, duct cleaning may be advisable for older houses following large renovation projects.

It’s always a good idea to have your ducts cleaned after a major renovation . Ripping down cabinets, tearing up old flooring, installing new electrical and drywall…it all creates a lot of nuisance dust and debris. Even when you cover the vents, bits and pieces of construction material can make their way into the ductwork.

This is just a basic test, but if the air ducts in your home look dirty, you should call a reputable air duct cleaning company like Power Vac .

Pet Dander in the Ductwork

Pet Hair in the Duct work can create Indoor Air Quality Issues

Many people young and old suffer from respiratory illnesses such as allergies or asthma. Asthama today is a common problem  It is also  estimated that 10 to 15 percent of this number overall is allergic to dog or cat dander. Most of us have our furry friends living indoors, this is extremely significant to the air quality of your home. Pet dander accumulates inside of your heating, ventilation, and air conditioning system , forcing the allergens to be released throughout your household when the furnace cycles. This in turn causes the air quality in your home to deteriorate.

Contrary to popular belief, pet dander is not animal hair. Dander is tiny flakes of skin, and is produced by each and every animal. This is the part that most humans are allergic to.

It is very easy to remove pet dander from your cat or dog. Regular bathing and brushing are all that is needed to do away with those pesky dander flakes.

There are a few things that you can do to help improve the quality of air in your home, and get rid of pet dander and irritating allergens. Many find it takes a combination of these methods to eradicate the problem permanently. It may take a few attempts before the situation is finally resolved.

Hepa Air Cleaners Remove Pet Dander from your environment

Adding HEPA air cleaners to your HVAC system can assist in eliminating allergens from the air. If you have a high efficiency furnace you should set your fan to auto or on, this will allow the fan to move air continuously, cleaning your air and removing viruses, dander, and bacteria.

Cleaning Your Forced Air System in an ideal way of removing Pet Hair and Dander

Pet hair , dust ,lint and other debris tend to buildup on furnace motors and fans. Once these contaminates accumulate, it drastically decreases the air quality in your home. It is necessary to the effectiveness of your furnace system, and helps to properly heat and cool the home and prevent expensive repairs.


Cleaning Ducts Can Help Rid of Pet Hair &  Allergens and Help Improve Air Quality in Your Home

As we operate the forced air system in our home, animal dander and other debris become lodged in the duct work and HVAC components . As these contaminates accumulate over time, your duct work is an optimum breeding ground for mold, bacteria  and fungus. Each time the system is switched on, these spores are ejected out and circulated through your home. Those who suffer from respiratory problems are especially prone to the effect of these contaminates.

By doing duct cleaning in your home every  3 to 5, your household’s IAQ can be greatly  improved. Cleaning the duct work can also help lessen the HVAC system operation time, resulting in lower heating bills, and restore the overall capacity of the system
