How to Winterize Your HVAC System
You may be ready for the seasons to change, but is your HVAC system? While it may seem like there is a seamless changeover from heating to cooling, there are actually some things that you should do to prepare your AC to go offline for the winter and your furnace to pick up the slack. Here are some steps to take to winterize your HVAC system.
Change Your Air Filter
Yes, we know we have said this over and over again, but it really is that important. Before you fire up that furnace, take a minute to clean out or change your air filter. Air filters are a very important part of your system and need to be cleaned on a regular basis to keep your HVAC system running smoothly.
The change can be very important if your heating and air conditioning are handled by different units. The summer can bring a lot of dust and dirt with it, which clogs up that filter. Remember: change your filters every six months.
Remove the Window Units
If you have window units for your cooling needs, it is time to remove them. While it may seem okay to leave them in the window because the unit will keep out the cold, leaving it in can actually cause excess wear and tear on it. If your window or wall units are not removable, make sure to cover the unit up for the winter. This will keep the seasonal dirt off of the heat exchanger. A dirty heat exchanger makes for a poorly working air conditioner in the summer.
Outdoor AC Unit
If you do have a combined AC/furnace unit, then you probably have an outdoor air conditioning unit. Since this unit is going to be sitting idle for a few months, now is a great time to clean it off. Start by removing any loose debris from around it. If you have plants grown nearby, make sure to cut them back to leave your outdoor unit plenty of space.
Once you get the unit cleaned up, it is time to cover it. You don’t want to cover it the whole way; that can actually trap moisture inside and cause your heat exchanger to rust. Winterize your HVAC system by covering it a little less than halfway. That will keep the majority of the weather off of it and protect it through the fall, winter and early spring.
If you have any outdoor plumbing and you live in an area where it may freeze up — i.e. the Nevada desert at night — you need to do a few things to winterize it. First, remove any hose that might be attached. If there is water in the hose and it freezes, you can damage the hose and faucet. If you don’t have a frost-free faucet, turn the valve to the outside off inside of your home. This will prevent frozen pipes.
