With record low temps this year in Chicago it is very important to have your heater working properly. If it isn’t you can call Around the Town HVAC for Chicago area heating repair immediately.
Troubleshoot some of the issues by checking the breaker or the pilot light. If you find you pilot light is out be sure to follow the re-lighting instructions to get it working again.
If it is going to take some time to fix your heater then you may want to consider getting some space heaters, or using your fireplace. Do not rely on blankets alone to keep you warm. Another good suggestion is to keep the opening of doors and windows to as little as possible. If you do not have a space heater or fireplace you may want to consider staying in a hotel until your heater is fixed. One last note, if you plan on using space heaters be very careful to keep them away from anything flammable.
