5 Ways to Prepare Your HVAC System for Winter

Winter is quickly approaching, meaning it’s time to prepare your HVAC unit for the transition from cooling to heating. Given that your HVAC runs all year round, it’s crucial to keep it in good shape for the winter. The last thing you want to find yourself doing is dealing with a cold home when the chilly weather finally kicks in.

There is much to do when addressing your HVAC needs in cold temperatures. You must take care of your system to make your home comfortable and ensure you have no issues with changing seasons. Here are some tips to help you prepare your HVAC system for winter

1. Schedule a professional tune-up

Scheduling a professional heating system tune-up is one of the best ways to prepare your HVAC system for winter. You should have your HVAC unit regularly checked, inspected, and serviced as preventive maintenance.

During the regular tune-up, a technician will thoroughly inspect the furnace and make necessary changes to ensure safe combustion and venting out of the products inside the system, giving you an HVAC system with improved energy efficiency and high performance.

2. Conduct a sound check

After a thorough check-up and cleaning, turn on your system again and listen for any unusual noises that may be a call for concern. A continuous rattling or banging sound after the system is up and running for a while might indicate an issue that requires further investigation. Be sure to call a professional technician to check all the electrical connections and wiring.

3. Change air filters

Air filters protect your HVAC system from dirt, dust, and debris. However, if you don’t change them regularly, you put unnecessary stress on the entire system since these filters, over time, get clogged with lint and debris, making your furnace work harder to pull air through them. Change your HVAC filters regularly, at least every six months, or as often as once every one to three months if you have pets in your apartment.

4. Check your humidifier

Most homeowners use a whole-house humidifier to regenerate moisture that is probably missing from the winter air. This device is installed as part of your HVAC unit and requires quick inspection and maintenance as much as your heating system.

Remove and clean your system’s water reservoir to eliminate microbes and mineral scale deposits that may have started to accumulate with frequent use. In addition, the humidifier’s water panel should be replaced before the heating season to ensure maximum efficiency from the system come winter.

5. Do a test run

Ensure you turn your furnace system on at least three times before winter arrives. You don’t want to turn your furnace on the first freezing day only to find that it’s no longer working. Testing your furnace before the weather changes will ensure it’s running correctly and heating your home efficiently. Furthermore, you can take your time to find a company to repair your unit if there are any issues.


It always pays to be prepared for the worst the winter season has to offer. Fortunately, you can work to get your HVAC system ready for this season’s cold with a few simple steps. Follow these essential tips to ensure your HVAC system functions smoothly throughout the winter.
