3 Signs Your Furnace Is Due for Repair

Southern California is blessed with an abundance of warm weather throughout much of the year. In fact, it’s one of the main reasons why people choose to live and vacation here. Homeowners tend to rely on their air conditioners much more than their furnaces. 

But that doesn’t mean you can get by without having a reliable heating system. When the weather turns chilly, there’s nothing worse than being unprepared for the cold spell than realizing you need furnace repair for an uncooperative heating system.

From a furnace that doesn’t blow warm air, to one that’s short cycling, let’s look at 3 signs your furnace needs some TLC from the Command Comfort team.

1. Lack of Hot Air

When your furnace is running efficiently, you should feel hot air coming from the vents. The air shouldn’t feel lukewarm and it definitely shouldn’t feel cold. Hold your hand up to a vent to check the airflow. It should feel distinctly warm, leaving you with no doubt about its heating ability.

If your furnace isn’t blowing hot air, you’ll notice it may take what seems like forever for your home to heat up. Your furnace might not be able to achieve the temperature on the thermostat. 

Cold or lukewarm air from a furnace is indicative of several possible causes. The first thing you should check is the air filter. If it’s dirty, dusty, or even worse–completely clogged with a thick layer of gunk–replace it with a new one and see if that fixes your airflow problem.

If it doesn’t, there could be an issue with the blower fan. This is the part of a furnace that blows the heated air into the rooms of your home. Whatever the cause of the problem, this requires a professional HVAC technician to diagnose and fix it. Don’t keep paying to heat your home without achieving the cozy warmth you desire.

2. Strange Noises

Your furnace is a smooth operator, running so quietly that you can barely hear its operation other than the “whoosh” of hot air coming from the vents. So when it starts to make strange sounds, you’ll notice it immediately.

Common noises from a furnace that mean something is wrong include banging, screeching, grinding, booming, and rattling. These sounds could indicate anything from a loose part to a broken component. 

If you have a gas furnace, a booming sound is concerning. This usually means there’s a delay in the ignition process either due to a faulty ignition system or dirty gas burners. No matter the sound, contact us promptly for a furnace that’s making a loud fuss. You don’t want the problem to get worse and potentially more costly to fix.

3. Short Cycling

Short cycling is just what it sounds like–a furnace that goes through many “short cycles” of turning on and off. But those cycles are too short to complete a heating cycle. You’ll notice your furnace seems to be running all the time, but your home isn’t getting warm enough. Short cycling is hard on your furnace. Schedule service with us ASAP to remedy this problem.
