4 Heating System Noises You Shouldn’t Ignore

January 7, 2025
It takes a few minutes for the fan of a furnace to finally start that familiar whir sound. That’s because it takes a few minutes for the furnace plenum to actually heat up after the burners light, and the fan does not start running until it is warm enough to deliver air to the vents in your home. Once you do hear that spinning, whirring blade and the rush of air through the vents, it’s a satisfying sound—unless it’s accompanied by an unfamiliar noise.
Other than the sounds you are familiar with as your furnace starts up, you should not expect to hear much else as the system runs. If you notice noises from the vents or the unit itself, it’s usually time to call in technicians. Here are 4 of them you cannot afford to ignore.
1. Loud Bang at Startup
We’re going to start with the noise that likely scares you the most, when you hear a loud banging noise coming from the furnace. If this happens consistently, rather than when the furnace first starts up, it could have to do with the air ducts or the sheet metal siding of the furnace expanding and contracting, the result of poor duct installation or improper furnace sizing.
If this happens only at furnace startup, though, you have reason for concern. This may be due to something as simple as a dirty furnace burner. However, that dirt allows gas to buildup, causing a sort of mini explosion when the burners finally do ignite! While it may not affect your home right now, this rattles the heat exchanger, which could eventually crack and leak poisonous carbon monoxide into a home.
2. Squealing
That squealing you hear from the furnace may be the result of a lack of lubrication or a blower fan belt that is wearing out. This means it’s an easy fix for most technicians, so why is it such a big deal? Because, if you let it go on for too long, the fan may stop working, stopping the furnace from running when you need it most! It’s better to repair the problem now than to wait for a system breakdown.
3. Low Rumble
If you hear a low rumbling noise, it’s probably loudest when you are right near the unit. It’s hard to say what the cause is without seeing and hearing the furnace ourselves. One common explanation, though, is that the pilot flame is too low. Check the flame to be sure it is blue rather than yellow or orange. Otherwise, a rumbling noise could be attributed to a dangerous carbon monoxide leak, depending on the unit, so shut off the system and call for help if you believe this may be the case.
4. Scraping
Finally, we don’t think a scraping sound—like metal on metal—should ever be ignored within a furnace. Most likely, the motor mount has come loose from its casing. In other words, it’s just what it sounds like: metal scraping on metal. This might not seem like such a big deal right now. However, the damage that can result to the blower fan may be severe enough to require replacement, whereas it may only need quick repairs if scheduled right now!

If you live in Ketchum, Hailey, Sun Valley, or Bellevue, you know that keeping your home warm during the cold winters of the Wood River Valley is a top priority. One crucial part of maintaining your heating system is changing your furnace filter regularly—but what happens after you replace it? Many homeowners wonder: 👉 Are furnace filters recyclable? The short answer is: most furnace filters are NOT recyclable due to their mixed materials. However, there are still eco-friendly ways to dispose of them. Let’s dive into why most filters can’t be recycled and what you can do instead. Why Can’t Most Furnace Filters Be Recycled? Standard furnace filters are made up of several different materials, including: ❌ Fiberglass or polyester fibers – These trap dust, allergens, and debris but are not biodegradable or recyclable. ❌ Metal or plastic frames – Some filters have metal or plastic components, which would need to be separated before recycling. ❌ Wire mesh or cardboard – While cardboard can sometimes be recycled, it’s often contaminated by dust and dirt, making it non-recyclable. Since these materials are fused together, most recycling centers in Wood River Valley, including those in Hailey and Ketchum, do not accept used furnace filters. Eco-Friendly Ways to Dispose of Furnace Filters Even though you can’t toss your old filter into the recycling bin, here are some better disposal options: 1. Check with Blaine County’s Waste Management The Ohio Gulch Transfer Station serves Ketchum, Sun Valley, Hailey, and Bellevue, and they may have guidelines for proper disposal. While they don’t currently recycle furnace filters, they can direct you to the best disposal method. 2. Reduce Waste with Reusable Filters Instead of tossing filters every few months, consider switching to a washable, reusable furnace filter. These can last for years and reduce landfill waste. 3. Use HEPA Filters Responsibly HEPA filters, often used for improved indoor air quality, are even more difficult to recycle. If you use one, check with your HVAC provider (like us at Evans Plumbing, Heating, and Mechanical) for proper disposal tips. How Often Should You Change Your Furnace Filter in Wood River Valley? Because our region experiences cold winters and wildfire smoke in summer, furnace filters in homes across Hailey, Ketchum, and Sun Valley can clog up faster than usual. 📌 Every 1–3 months – If you have pets, allergies, or use your heating system frequently. 📌 Every 6 months – If you have a high-efficiency system or don’t use your furnace as often. 📌 Every 30 days – If you have severe allergies or rely on your HVAC system year-round. A clogged filter reduces efficiency and increases energy costs, so staying on top of replacements is key. Need Help with Your HVAC System? Call Evans Plumbing, Heating, and Mechanical!

As energy efficiency and sustainability take center stage, heat pumps have emerged as one of the most sought-after HVAC solutions. These systems, which provide both heating and cooling, are rapidly gaining popularity among homeowners and businesses looking for cost-effective, eco-friendly alternatives to traditional furnaces and air conditioners. Let’s explore why heat pumps are revolutionizing the industry and whether they’re the right choice for your home. What Are Heat Pumps and How Do They Work? Unlike conventional heating and cooling systems that generate heat or cold air, heat pumps transfer heat from one place to another. In the winter, they extract heat from the outdoor air (or ground) and move it indoors. In the summer, they reverse the process, removing heat from inside your home to cool it down. There are three main types of heat pumps: Air-Source Heat Pumps (ASHPs): The most common type, which transfers heat between indoor and outdoor air. Ground-Source (Geothermal) Heat Pumps: These systems extract heat from the ground, offering exceptional efficiency but requiring installation of underground piping. Water-Source Heat Pumps: Used in properties with access to a nearby water source, such as a pond or lake. Why Are Heat Pumps Gaining Popularity? Several factors are driving the widespread adoption of heat pumps: Energy Efficiency: Heat pumps are significantly more efficient than traditional furnaces and air conditioners because they move heat rather than generate it. Lower Utility Bills: With high efficiency comes reduced energy consumption, translating to long-term cost savings. Environmental Benefits: Heat pumps reduce reliance on fossil fuels and lower carbon emissions, making them a sustainable option. Government Incentives: Many regions offer rebates and tax credits to encourage homeowners to switch to heat pumps. Year-Round Comfort: A single system provides both heating and cooling, simplifying home climate control. Are Heat Pumps Suitable for Cold Climates? One of the biggest concerns about heat pumps is their performance in colder climates. Fortunately, modern advancements in heat pump technology have led to the development of cold-climate heat pumps , which can effectively extract heat even in subzero temperatures. If you live in an area with harsh winters, look for a model specifically designed for extreme cold. What to Consider Before Making the Switch Before installing a heat pump, consider the following: Upfront Cost: While heat pumps offer long-term savings, the initial investment can be higher than traditional systems.
