If you have plans to take a vacation, you need to plan on how you will deal with your HVAC system while you are away. You need to decide how your system will cycle while you are away so you come back to a comfortable home. Here are some things you should do while you are away from home for a period of time.
Leave the System On
One common mistake some homeowners make is turning the entire system off when they leave on vacation. A HVAC is designed to run consistently. If the system is inactive for a long period of time, it may not work as well once you turn it back on when you get home. After a long dormant period, the components have trouble turning back on. Additionally, moisture can build inside the components, which can result in mold and mildew.
If you do not want the system to cycle as often while you are away, turn the thermostat up higher than you would normally. This leaves the system on, but prevents it from running as often. This will keep the system running enough to keep it in optimal condition.
Check the Weather
Before you go away, be sure that you check the weather forecast. Bad weather can happen at any time, so you should have a plan in the event you lose power while you are away so you can plan for storm damage. Prior to leaving, take the time to remove any low-hanging branches and remove anything from your yard that can blow away and hit your HVAC system.
Look at Your Vents
You may think that closing off the vents in some rooms of your home will help regulate the temperature and keep some rooms colder than others. While this can be helpful, go around your home and open up the vents in every room. This will help the air flow more freely. Your HVAC system will work more efficiently when there is maximum airflow throughout the house. It will also not cycle as often.
If you seem to notice anything strange about your HVAC system before you leave on your trip, be sure to have it inspected by a licensed HVAC technician. You do not want to deal with a malfunctioning air conditioning unit when you get home. This may be a good time to have a routine inspection done as well to ensure your entire system is running well.
