Common Heating Problems in Furnaces & Heat Pumps

Your furnace can run into a whole slew-and-a-half of problems, but so can your heat pump. Truth be told, there’s no HVAC system that exists or ever will exist that won’t have its fair share of problems, so you might as well know what you’re getting into.

Through various heating repair in Sugar Land, TX, we’ve seen just about every type of request you can think of, from the oddball damages to unique fixes and beyond. Before we jump the gun and assume it’s something strange that’s causing your heater to give you trouble, let’s take a look at the most common issues first.

Airflow Issues

Both heat pumps and furnaces are forced air systems, meaning they need proper airflow coming in to provide airflow going out. If your filter is clogged and hasn’t been switched out in quite some time, that’s an indicator that your heater isn’t getting the right amount of air.

This impacts all sorts of performance on the interior of your unit, but it’s most noticeable when you listen to how long your heating cycle runs for. Your heater will still do its job, but at a much less efficient rate. Your house will warm up, but it can take a lot longer than it’s supposed to. In short: you’re spending more money just because you haven’t switched out a $6 air filter. Make it a habit to put a new filter in place every 30 days.

Dirty Flame Sensor

With a furnace, you have a line of gas coming in that feeds the flame, then combustion occurs in the unit to produce heat. At the point of that live flame, there’s a flame sensor that acts as a gatekeeper. It prevents the flow of gas from coming in unless it can detect a flame.

Live flame? Gas can come on through. When the flame goes out, the flame sensor shuts the gas line to prevent it from filling up the air you breathe and becoming a fire hazard. But when that flame sensor gets dirty, it can stop detecting a live flame even when one is there. Get it cleaned by a professional, and you should be good to go.

Thermostat Problems (Plot Twist)

Your furnace or heat pump might not have anything wrong with it. In fact, it could be the thermostat’s fault. Your thermostat is a gauge that detects the current air temperature, and sends signals to the heater to tell it when to turn off and on.

So if your thermostat isn’t reading the temperature right, your heater isn’t going to get those signals that it needs. It’s just waiting on instructions, which is why it’s good to make sure your thermostat is calibrated properly before you call for needless heater repairs.
