When you have built an attached garage, you will need to think about adding some ventilation to the area. Ventilating garages properly is vital for two reasons: first, the fumes and chemicals which are connected with keeping a car, or using power tools, means that you need to draw these away from the rest of the house, and second, heat build-up in an attached garage will also make the house very hot during the summer months. In order to properly vent your garage, you need to know what to look out for, and the right kind of materials for ventilation. Once you know your garage, you can install an exhaust fan kit.
Step 1 - Check Out Your Garage
If you don't already know how large your attached garage is, then you should use a tape measure to measure the length and width. This will allow you to work out the total area that you need to ventilate. Make sure that you know this detail, as it can affect the type of exhaust fan kit that you purchase.
You should also go up to the ceiling of the garage, and look above it. If you have a one-story attached garage, then you may find a small crawl space, which you will need to negotiate when adding ventilation. A roof which has been put straight on the garage ceiling is probably best for your purposes.
Step 2 - Purchase an Exhaust Fan Kit
When you have worked out what your garage is like, then you can start looking for a garage exhaust fan. A self-installation kit is probably the best variety for the needs of an attached garage. Make sure that you buy one which has enough power to ventilate the entire garage.
Step 3 - Prepare the Room
Cut a suitable hole in your garage ceiling for the exhaust fan, and then locate the electrical wiring box for the garage. Turn off the power, and run extra wires from the nearest junction box to the hole you have just created. Use wire cutters to trim the wire down to the right size. You may want to use an old electric light connection, and simply use the wires from this.
Step 4 - Install the Fan
When you have done this, connect the exhaust hose to the fan, and push it through the roof until the nozzle is completely through. Secure it to the outside of the roof with the brackets provided in the kit. Wire up the fan, and then screw it onto the wall using the screwdriver. Make sure that the fan is securely fitted in the hole, and then caulk around the edge of the casing to ensure that air doesn't escape back inside. Turn the electricity back on, and check that the fan is working. Leave it to run for about an hour before turning it off.
