Steam furnaces heat enclosed living spaces with propane or natural gas. Although gas is often portrayed as a costly source of fire, gas furnaces burn cleaner than oil furnaces and need less repairs. When issues do arise with gas furnaces, though, they’re usually simple to spot and fix. The following are four typical problems with older gas furnaces, as well as what you should anticipate in terms of repairs.
There is no heat generated by a furnace.
If your gas furnace isn’t producing heat, it’s most likely due to a closed control valve, a blown fuse or tripped circuit, a defective thermostat, or a non-functioning pilot light. Although you could fix these issues yourself, if you aren’t familiar with gas furnaces, it’s safest to contact a gas furnace repair service (i.e. a heating and cooling company). Regardless of which of the above problems the furnace is having, an HVAC repair specialist should be able to fix it the next day, and neither of the problems would cost a lot of money to fix.For further information regarding this,more info here.
Insufficient Heat is Generated by a Furnace
It’s possible that the furnace is making less heat because the blower is clogged, the blower belt is loose, or the filter or burner is filthy. These issues may also happen at the same time. A furnace that generates inadequate heat as a consequence of one of the above problems will normally be replaced the same day at a low rate, much like a furnace that produces no heat. If a gas furnace repair mechanic says the trouble is caused by one of the above problems but that any of the others are on the way, save money and get them all fixed with one visit.
A Furnace Is Always Turning On and Off
Your furnace is most definitely suffering from a clogged blower, a filthy cleaner, or an excessively dry motor if it turns on and then turns off before delivering the required amount of fuel. In the first scenario, a technician may vacuum the region around your blower; in the second case, the technician may replace your temporary air filter or clean and reinsert your permanent air filter; and in the third case, the technician will lubricate the engine by inserting oil in the appropriate oil ports. In any event, the service fee can be kept to a bare minimum.
The Pilot Light on a Furnace Won’t Switch On
If the pilot light is on, you will say by standing on the floor and gazing at the underside of the furnace, where a tiny blue flame can emanate from a small pipe if the pilot light is on. A clogged pilot opening, inadequate gas flow due to an incorrectly set gas valve, or a broken thermocouple are the most common causes of a pilot light that won’t light.
