To stay warm in San Marcos, TX, you need a furnace. The furnace should run efficiently, though, or else you’ll pay more than you should on your utility bill. By knowing the signs of an inefficient furnace, you can get any necessary repairs done in a timely manner.

Higher Utility Bill

The first possible sign should be obvious to any homeowner. If your bill has gone up in the absence of any significant change either in the weather or to your thermostat settings, then you know that the furnace is failing to do its best job. Normally, you’ll find this paired with other tell-tale signs of inefficiency.

Shorter Length of Cycles

Unusually short cycles (several seconds) and unusually long ones (longer than one hour) denote a problem, too. The former can occur as a result of a malfunctioning thermostat, a dirty flame sensor, or an overheating unit, while the latter can happen because of clogged filters and vents. Having an oversized unit can cause short-cycling, too, whereas an undersized unit would cycle for extremely long periods.

Blowing Cool Air

Perhaps the air blowing out of your HVAC system feels cool. This is a complaint we hear a lot from homeowners. We can easily find a solution to it via regular maintenance.

The problem may lie with the flame sensor mistakenly believing that the pilot light is out and cutting off the gas supply, or it may lie with dirty filters. Leaking ducts provide a third possibility, in which case you would want us to seal them up.
