(WXIA) -- Button up. Atlantans are getting a first taste of the chilly blast of winter coming our way. It's not severe yet but it's enough to test our bodies and, of course, our heating systems.

When the temperature goes down Bashar Komery of Komery Mechanical Systems has to go into some tight spaces.

"Most of the time it's a lot of heat pump systems like this you know when it gets real cold and a lot of times with the new systems like this when they turn the heat on for the first time," Komery said.

To avoid a system breakdown, Komery said to get your system checked early before extreme temperatures kick in, change your filters often because clogged filters can cause problems and shorten the life of the equipment and always keep a trusted and reliable HVAC contractor number handy and avoid calling on the holidays unless it's a real emergency.
