Check To See If There Is An Easy Solution

If you go to turn on your thermostat and nothing happens, don’t run to call a technician right away. It could have a simple solution that you can find yourself through a little troubleshooting. These simple steps could save you time and money before picking up the phone.

Do Your Research

Still not working? Time to ask yourself a few questions and do some research.

  • When is the last time you had a service technician out to clean your HVAC?
  • When is the last time you changed the filter?

As a general rule of thumb, it’s important to have your furnace checked by an HVAC technician at least every other year, if not more. A specialist will tell you if anything is a concern or needs to be fixed before you run into the issue of it not working on a cold day.

Your filter should be changed every month to every 6 months depending on the type of filter you have. A clean filter is a top priority when it comes to keeping your HVAC running smoothly. Dirty filters can hinder airflow and lead to more problems – with parts deteriorating and the system malfunctioning.
