Furnaces have a big job to do. During the winters in Fairfield County, they are running every day for months, trying to make your home cozy despite the harsh weather outdoors. So it’s understandable that they make some noise. But sometimes, noises can be the result of your furnace having trouble or needing repair. What sounds are the natural result of your furnace doing its job, and what sounds should cause you concern?
The first thing to understand is that your furnace’s sounds should be consistent. You should hear it humming along during the heating cycle, and if you have a ducted or forced-air system, you will also hear the gentle whoosh of the fan pushing the heated air into your home. Any unexpected, different, sudden, or loud sounds are worth paying attention to. Here are some sounds that may occur when your furnace encounters a problem.
Ah, autumn! It’s time for putting pumpkins on your doorstep, curling up with a mug of spiced cider, and turning on your furnace for the first time—wait, why does it smell like something’s burning?
While you’re enjoying the beautiful weather and foliage of autumn in Connecticut, keep in mind that the heating season is just about here. If you haven’t had to turn your heat on for a cold night just yet, you will soon. And when you do, you want that heat to be reliable. We hope you heeded our advice and scheduled your heater maintenance so you can be aware of any concerns before you require heat. But even if you did, it’s important to be aware of the signs that indicate your heater needs repair. 
What’s that you say? You’re still using your air conditioner, so it’s not really fall yet? Well, perhaps there will still be some hot days, and then there will certainly be some mild ones, but we all know that the days are getting shorter, and winter is creeping closer. It’s time to schedule heating maintenance because you don’t want to be caught by surprise when the first truly cold weather arrives.
You may have encountered this scenario in many aspects of your life: something has gone wrong, and instead of having it addressed promptly, you delayed repairing an item or system. You kept using it. Then, when you finally got around to seeking repairs, you found that ignoring a small problem had caused a much larger problem to occur. This can happen with many things—a bicycle, a car, a gutter on your house. And it can definitely happen with your air conditioner. 
Your air conditioner’s refrigerant is one of the most important parts of your cooling system. You’ve likely heard of “Freon”, or R22, which was recently phased out in favor of the more eco-friendly Puron, or R410A.
