Air Quality

Today's homes are airtight marvels. Improved design and insulation dramatically reduce energy consumption and waste. Drafts are almost unheard of. Heat has virtually no means of escape.

However, if heat cannot escape, neither can excess humidity or indoor pollutants.

Without an exchange of air, the effects of everyday living (cooking, cleaning, smoking, pets, etc.) can adversely affect the quality of the air you breathe-and the environment in which you live becomes uncomfortable and unhealthy.

Adding a Carrier HRV to your ventilation system will solve these problems. Designed for quiet operation and above all, reliability.

How Heat Recovery Vents Work:

   1. Vents located throughout the house draw in stale and humid air.
   2. Heat recovery core removes heat from stale air before it is expelled outdoors.
   3. As air is expelled, HRV simultaneously draws in fresh air from outside, warming it with heat recovered from the indoor air.
   4. Fresh, warm air is released throughout the house.
   5. All models include filters which trap dust particles.
   6. Some models may include an air ionizer which eliminates finer particles such as pollen and smoke from the air. Also helps neutralize harsh odors-pets, tobacco, cooking etc.

HRV are installed only by professional contractors or heating/ventilation specialists. Ducts are hidden inside the walls and network throughout the house. All you see are the air vents. Where forced air heating is used, installation is simplified as the distribution ducts and be shared effectively by both systems.

20 Steps to a Professional Duct Cleaning

1. A trade professional will arrive at your door in a custom built duct cleaning truck. He will need to park in the driveway or on the street within about 30 feet if possible. 
2. The technician will be uniformed in coveralls. 
3. The technician will wear booties when entering the home if boots are not removed. 
4. The technician will look at the home to determine the best entry point for the hoses to come in (front / side / back door or basement window). Note that this entry point will need to remain partially open for the duration of the job (please have children and pets contained for this reason). 
5. The technician will go over the job with the customer and answer any questions. 
6. Drop sheets will be put down where the vacuum hose will be brought in as necessary. 
7. All supply and return vents will be covered with magnetic strips to keep the home as clean as possible. 
8. The technician will bring a long vacuum hose into the furnace room (8" in diameter). 
9. The power to the furnace must be turned off for the duration of the procedure and furnace filter removed. 
10. An eight-inch hole (the size of the vacuum hose) will be cut in the supply ductwork to accommodate the vacuum hose. More than one may be necessary to do a proper job, at no extra charge. 
11. A zone bag or foam is used inside the supply main line to act as a barrier, ensuring no dust from the procedure ends up in the furnace itself. 
12. The vacuum hose is then hooked into this opening. (This is where the negative pressure comes from.) 
13. As the suction draws from the basement, we go upstairs with a small airline hose (1" diameter) and use a Blowgun to force the debris down each individual supply vent using 250psi air pressure. This air-wash method loosens all the contaminants and forces it down into the main lines in the basement. 
14. Now that all of the contaminants are in the main lines, one-inch openings are made to accommodate the Scorpion Rod System, which agitates inside the ducts, loosening hardened debris, and then the Air Snake, which propels itself through the lines and is used to draw all of the debris back to the vacuum hose, which is then suctioned out to the 
truck. 
15. Steps 10-14 are now completed for the return side of the ventilation system. 
16. The J-Channel and around the furnace filter is cleaned with the Blowgun and vacuum. 
17. Next, the duct system is fully disinfected at no charge to kill any mould, mildew, bacteria or fungi. It is an all-natural product, which is not harmful to breathe. It has a clove and lemon scent, but dissipates within about a half an hour as there is no chemicals to bond the scent there. 
18. All 1" holes are sealed with black plastic plugs and the 8" holes covered with 10"x10" sheet metal plates and secured with screws. These will all act as access openings for the next cleaning in 3 years or so. 
19. The furnace filter is put back and power to the furnace is turned back on. 
20. The technician will take a second look to ensure that no vents were missed, any mess around them is vacuumed up, the furnace is working in the same capacity as it was upon arrival and that cuts to the duct system have all been properly sealed.
