Why You Should Prepare Your HVAC System for Winter

Posted: 2019-10-24

The temperatures are dropping as winter is fast approaching. The cool chill in the air reminds us that the full swing of another cold Minnesota winter is just around the corner. This is the perfect time to prepare your HVAC system before it starts to work full time in the coming months.

Preparing your HVAC system for the cold weather is commonly called “winterization”, which is a process involving the preparation of the whole home comfort system before it gets extremely cold. This process includes a number of steps and the goal is to make sure your home is kept comfortable and safe, especially when winter is at its coldest.


First and foremost, scheduling professional maintenance is the most effective way to ensure your equipment is working in accordance with the manufacturer’s specifications even in the winter.

Having your HVAC system inspected by a qualified HVAC professional before the winter is in full swing gives you enough time to identify and manage repairs. The technician can detect small issues and replace parts before they cause your system to completely shut down. As a result, winterization allows you to perform your daily tasks without having to worry about your HVAC system’s performance.

You won’t be needing your air conditioner over the next few months.  Winterization helps you ensure it is kept safe even when it sits idle. By keeping your outdoor unit free from water and debris, the chances of rusting, clogging, and other forms of damage are minimized. Furthermore, covering your AC protects it from damage and keeps it protected from wind and snow. You also have to disconnect the AC from the power source, which will save you money on utilities during the cold season.

By protecting your HVAC system in the winter, you are taking a step toward extending its life. No HVAC equipment really lasts a lifetime but winterizing does prolong its usability. There are certain components that are not as durable in cold weather as you’d want, but winterization ensures your unit is safe from precipitation and all equipment parts are safe. This is what extends your HVAC system’s lifespan.

How to Winterize Your HVAC System

Change the filter.

No matter the season, replacing your HVAC system’s air filters is a great way to ensure its energy efficiency. The filter acts as a barrier that protects your system’s internal components from dust, dirt, and debris. Regular filter replacement ensures the system has proper airflow, which is essential to the smooth operation of your equipment.

Check the thermostat.

Your thermostat has a very specific job: to tell your HVAC system to start or shut down. It also controls how warm or cool your home is going to be. When your thermostat fails to perform its task, it’s going to cause a great discomfort to you and your family. To avoid this dilemma, test the thermostat before winter gets unbearably cold.

To do this, turn your furnace or heat pump on, and if it fails to control the temperature, then your thermostat is faulty. Turn the power off to the heating system. Then, open the thermostat cover and look for corrosion. Clean it up with electronic contact cleaner. If it’s still not working, consider getting a new thermostat.

Sign up for a professional HVAC maintenance.

To ensure your HVAC system is prepared for the heating season, schedule a preventive maintenance check with a qualified technician. A trained professional is able to perform all necessary maintenance tasks, which include thorough cleaning of the entire HVAC system, the inspection of internal parts, checking of ducts and vents, electrical wiring, controls, burners, and the heat exchanger.
