Here at Distinct Heating & Cooling, one question we get this time of year is what is the right way to shut down your cooling system for the winter season? In order to help you correctly prepare your system, we offer the following tips and suggestions.
1. Turn off the cooling system. Go to your thermostat and use the system switch to move the cool setting to off position.
2. Check the air filter on the system. The A/C system uses the same filtration as your furnace. You want to check and replace any filters that are dirty. It is recommended to replace filters with high quality air filters. If you need help determining what filter size you need or the best one for your system, do not hesitate to call one of our technicians.
3. Switch over the humidifier, if your system has one. It should currently be in the “summer” or “closed” position and you want to move it back to the “winter” or “open” position.
4. Outside, go to the electrical disconnect box and switch the power off to the outside A/C condensing unit. The electrical disconnect box is typically located near the unit and is often mounted on the side of the home. This step should be performed regardless of whether you intend to use a cover or not. It is worth mentioning, at Distinct Heating & Cooling, we do not recommend using a cover in most cases, since covers can actually do more harm than good.
Now, the air filter should have been inspected and replaced. The humidifier should be set to the “winter” setting. The power to the outdoor A/C condensing unit should be shut off. Next, return to the thermostat and use the system switch to move the setting from the off position to the “heat” position and adjust the temperature setting to your preferred temperature. Lastly, set the humidistat to the desired set point. After performing these steps you should be ready for the winter season.
