A furnace is used for heating homes. The most important component of the furnace is the heat exchanger, which separates combustion air from the breathing air. During the combustion, metal in the heat exchanger heats up and transfers the heat to the blower that distributes the air to the house. There are, however, times when the combustion air mixes with breathing air, and if left unchecked, it could result in serious health issues. It is, therefore, necessary to carry out regular inspections of the furnace to ensure that the heat exchanger and other components are in order and functioning properly. In the event of any damage that is beyond your capacity to handle, look for an expert who offers the Best Furnace Repair services.
There are indicators that can help you in knowing if the heat exchanger is damaged. Using a flash light, you can check for any visual metal cracks in the heat exchanger. Lack of any cracks does not mean that it is secure. You can engage experts from Horizon Services Inc. for advanced inspection using infra-red light. If there are metal breaks, soot causes discoloration of the metal. Continued penetration of soot results in accumulation of spots that are darker than the metal.
Cracks will allow carbon monoxide to enter the home. A carbon monoxide detector should always sound an alarm to show that there is a build-up of carbon monoxide. If the alarm does not go off when the test button is pushed, then know that it is faulty and look for professionals who offers the Best Furnace Repair services to correct the anomaly. Another indicator of a faulty heat exchanger is the change in flame. It usually happens when the combustion air mixes with the breathing air.
Before calling an expert to repair or replace your furnace, tell the technician about all problems you are aware of so that he or she comes fully prepared. You should be able to identify a particular problem and how long you have experienced it. Take note of the last time you changed your filter, and if the furnace is maintaining comfortable temperatures in the home. Lastly, it is important to tell the professional how old the system is, and whether the unit uses gas, oil or electricity.
