It's cold outside! Are you ready for snow or colder temps? It's a great time to have your HVAC checked by a local HVAC specialist in your area. They will come out and check everything and can often find problems that can be repaired before they become BIG problems like a total loss of service. Prices vary so it's worth shopping. You can typically get a contract for the season or the year that covers up to X units in the house. Something to consider, especially when we are facing extreme temps in the days ahead.
