The Importance of Checking the Gas Pressure in your Heating Unit


Indianapolis HeatingThe gas pressure in your heating unit is what allows the right amount of fuel, which can be either LP, natural gas, or propane, to get from the gas supply line to the heater's mixing tubes, where it mixes with air and powers the unit up. If the pressure is too low, there won't be enough gas going into the unit to properly power it up, and less heat will come out. If the pressure is too high, then there's too much gas in the lines, which can actually cause the heating unit to explode if left untreated.

Every furnace has a pressure release valve on it to ensure this doesn't happen, but if they break, then the danger still exists. There are also manual shutoff valves on every furnace to ensure gas cannot get into the unit in an emergency.

This means that the gas pressure on your heating unit should be checked by an HVAC specialist regularly, and the mechanism that controls the pressure should be regulated at least once a year, preferably when it starts to get cool outside. This way you'll know that it'll run without problems all winter long. If the gas pressure is already at abnormal levels, you should contact an HVAC contractor as soon as possible. They'll know what the pressure should be on your heating unit and how to regulate it.

When you're getting a new furnace, the contractor will be able to ensure that all the proper valves and mechanisms work properly, and also that the right amount of gas is going into the mixing tubes. They'll also clean the furnace, which also improves gas pressure, and they can detect leaks that people might not find if they try to fix this problem themselves. Most importantly, there's a lot less risk involved when hiring a professional than trying to fix it yourself.
