Anyone who has an HVAC system knows that they need to have regular maintenance on their systems in order for them to always be operating properly. When they aren’t working, there could be a number of reasons why. Some of these reasons are simple fixes that any home owner can take care of themselves. The obvious thing to check first is that there is power running to the unit. If everything is plugged in, turned on, and there are no fuses blown or breakers tripped, then the problem lies elsewhere.
If there are no issues with the power, the next thing to check are the thermostat settings. The fan switch should be set to “Auto” or “On”, and the system must be either on “Heat” or “Cool”, depending on the time of year. If it is summer time and air conditioning is needed, the thermostat should be set lower than the room temperature in order for it to work. During the colder winter months, the thermostat must be set higher than the room temperature before the heat will kick in. If there is still no heat, it may be time to call in the experts in HVAC repair in Harrisburg, PA.
If the thermostat is programmable, it could be that incorrect settings have been entered, and it is simply a matter of changing it to the correct setting. The next thing to check is the natural gas line, if it is a gas furnace. When the gas valve is open, the handle is supposed to be parallel to the pipe. Airflow is something else to check on. Make sure that supply and return grates are not blocked, because this can cause rooms to become too hot or too cold. Also check the air filter, and if it is dirty, replace it, or if it is a permanent model, clean it.
Once troubleshooting has been done, and if the system is still not working properly, it is time to contact professional technicians in HVAC repair in Harrisburg, PA to diagnose and repair the problem.
