From tropical getaways in the winter to long weekends at the cabin in the summer, Minnesotans love their vacation time. But while you’re getting everything in order before your leave, don’t forget about your HVAC system.

Your HVAC system is an essential part of your home, and making sure it’s in good working order before you take off will help avoid some potential headaches when you return.

Here is a handy checklist that can help you prepare your HVAC for the time that you’re gone: 

1. Set your thermostat.

Many people believe that turning your HVAC system off while you’re out of town is a great way to conserve energy and save a little money. However, we definitely don’t recommend this.

Your system is designed to run regularly for maximum efficiency. In addition, running it regularly during the really hot and really cold months will help minimize the risk of frozen pipes in the winter and mold or moisture buildup in the summer.

Instead of turning it completely off, we recommend setting your thermostat four degrees higher than your comfortable temp in the summer. In the winter, four degrees lower than your comfortable temp.

 2. Install a surge protector for your system.

A surge protector is an inexpensive and effective way to protect against a power outage or surge that could damage your HVAC system. If you’re don’t have one or need advice for selecting one, give your local HVAC company a call. 

3. Check the air filter and change it if necessary.

Your air filter is a small but vital component of your HVAC system. Your air filter catches nasty particles before they make it into the air or build up in your system. During peak summer and winter use, dirt and debris build up much faster, which can affect efficiency or cause other maintenance issues.

Check your air filter to make sure it’s relatively clean before you leave. If you need to replace it, here’s some guidance: 

• Select the right size. Remove your old filter and measure it, or read your user’s manual to find out what size you need.
• Choose a MERV. MERV stands for “minimum efficiency reporting value” and ranges from 1-20. The higher the MERV, the more effective the air filter.
• Pick the type of filter. You can choose from fiberglass, washable, pleaded or electronic.
• Install it. Most air filters are extremely easy to install. Just follow the manufacturer’s instructions.

4. Check exterior units for debris that may be restricting air flow.

Make sure any downed leaves, tree limbs, sticks and grass clippings are all cleared away. In addition, make sure any nearby shrubbery is trimmed and there’s at least two feet of space around the unit. This will ensure proper airflow. 

5. Close and lock all windows.

Not only will closing and looking doors and windows ensure security, but it’s another way to ensure your HVAC is running as efficiently as possible.

 6. Make sure all the air vents are open.

Closing off vents, registers or doors can cause efficiency issues, so make sure they’ll all open before heading out. 

7. Make sure your HVAC is clean.

When you keep your HVAC clean, it will run more efficiently and minimize maintenance issues. As mentioned above, one of the easiest things you can do is to regularly check and change your air filter. In addition, make sure that the burners, blower, flame sensor, pilot and hot surface igniter are free of dirt and debris.

8. Make sure maintenance requirements are up to date.

Every homeowner should have their HVAC inspected at least once a year. A great time could be before you leave to ensure something doesn’t go wrong while you’re gone.
