As a certified central air cooling systems installer, your company has the know-how to give your customers just what they need, and part of your customers' needs will include exhaust ventilation HVAC fans. These fans help filter contaminated inside air to the outside. They also help direct the warm air out of the home or business so the occupants inside can stay cool.

Another advantage (and thus, a selling point) to installing exhaust ventilation HVAC fans is that they slightly depressurize the building so moisture can evaporate. Moisture causes mold and mildew, and these are things every homeowner and business owner want to avoid. When getting started with a client, consider the following:

1. Calculate how much air needs to be vented. Every exhaust ventilation HVAC fans supplier will carry different sized products to ensure that you can meet every customer's needs.

2. Take the application into consideration. An exhaust ventilation HVAC fans distributor may specialize in some applications or offer products for a variety of applications.

3. Find exhaust ventilation HVAC fans online. Many online retailers offer wholesale discounts to contractors.

Action Steps
The best contacts and resources to help you get it done

Find a distributor of exhaust ventilation HVAC fans that sells attic fans

Attics are extremely hot, in fact, they can get up to 150 degrees Fahrenheit. Running an attic fan, with an optional whole-house fan, can greatly reduce the temperature of an attic and this allows the air conditioner to run more efficiently, effectively eliminating heat problems in upstairs rooms. An attic fan also extends the life of a shingled roof; as we all know, heat rises, and the heat trapped in an unventilated attic transfers heat to the shingles.

I recommend: Choose from the products available at AirScape. You can find a variety of whole-house fans at Whole House Fan.

Check out an exhaust ventilation HVAC fans store that sells wall-mounted fans

Wall-mounted fans are great for homes and businesses where roof access can't be gained. Vents can be installed into the existing ductwork and a fan can be placed at the end of a duct that runs toward an exterior wall. A hole is cut in the wall and the fan is installed, allowing warm or polluted air out into the open.

I recommend: Select from four different sizes at Southern Tool, which offers a box-style general purpose fan made in the United States. R.E. Williams offers a few different sizes of smaller wall-mounted exhaust fans.

Buy exhaust ventilation HVAC fans online for your commercial clients

Restaurants and manufacturing plants have special needs because they produce so much steam, smoke and fumes. Residential-grade exhaust fans just aren't adequate for these businesses, so finding and installing the proper ventilation systems is imperative.

I recommend: Find several choices of restaurant-duty fans at Ventilation Direct. Check out the huge selection of heavy-duty fans at Standard Equipment.
