Most heaters that fail haven’t been seen annually by a qualified HVAC company. It is important to have your heater looked at once per year from an efficiency and safety perspective. All heaters have fail safes to keep them from causing catastrophic failure. Your heater has flame sensors, pressure switches, and other items to keep them running safely. Most service repairs for heaters are needed when they are first turned on at the beginning of the heating season. And of course many homeowners do this the same chilly night. Before that chilly night comes, test your heating system by turning it on and letting it run for thirty minutes. If it doesn’t work, you will have more flexibility scheduling the repair and won’t be left out in the cold!
