HVAC units are one of the most reliable appliances in our family homes, however sometimes you will encounter a problem. Many times, you can take care of these problems on your own, but for more complex troubles, it is best to call a professional HVAC technician. The most typical things an HVAC professional definitely will check is blown fuses, worn contactors, capacitors, gas valve, filtration, thermostat, drain lines, refrigerant leaks, and lastly the compressor. The fuse is what protects your compressor from overheating, so if your HVAC system is not properly heating or cooling, the breaker is among the most first things to be looked at. Contactors and capacitors keep a person’s system running smoothly, and if they are worn or burned out, they will need to be replaced. Sometimes, your gas valve will get corroded, limiting the flow in the gas line to your unit. If this is the condition, it will need to get replaced. Cleaning or replacing your air filter is among the easiest things that you can, and should do yourself. A clogged air conditioning filter will cause your HVAC unit to run inefficiently, and may even lead it to seize up. Before calling a professional HVAC technician, check to make sure your thermostat is turned on. It can easily be switched off or put on the mistaken setting. Drain lines should be cleaned regularly. Refrigerant leaks, problems with your compressor or coils are all problems that must be handled by a professional. Your HVAC system should run safely and effectively for years, if you have it maintained regularly by a professional HVAC technician.
