7 Reasons Why Your Furnace Is Making Strange Noises

The chilling winter breeze is starting to make its presence known in Milton, DE. Many homeowners are eagerly preparing for cozy evenings by the fireplace or perhaps enjoying a warm drink at a local café. But as the temperature drops, our reliance on our furnaces in Milton, DE, increases. Now, imagine settling down on a cold evening and hearing a strange noise from your furnace. Disturbing, isn’t it? At Top Flight Heating & Air, we understand how unsettling furnace noises can be. 

Understanding the Sounds of Your Furnace 

When your furnace starts making unfamiliar sounds, it’s more than just an inconvenience; it might be signaling a cry for help. A well-maintained furnace is not only vital for comfort but also for the safety of your home. Ensuring regular furnace repair in Milton, DE, can make all the difference in your heating experience.

Why Is Your Furnace Making That Noise? 

Before you dismiss these noises as mere quirks of an aging system, consider these potential causes. Being informed is the first step to ensuring a safe, warm environment for your family:

  • Loose or Broken Belts
  • Ignition Problems
  • Dirty Burners
  • Blower Motor Issues
  • Duct Expansion and Contraction
  • Leaky Air Ducts
  • Unsecured Panels

Loose or Broken Belts

When you hear a high-pitched squeal coming from your furnace, it’s often a sign of a loose or broken belt. If neglected, this seemingly minor issue can result in inefficient heating, making your home feel less comfortable during those chilly Milton nights. With Top Flight Heating & Air’s expertise in furnace repair, we can identify and resolve belt issues promptly. By addressing these concerns early, you not only extend the lifespan of your furnace but also ensure optimal energy consumption, helping you keep those utility bills in check. 

Ignition Problems

A furnace that doesn’t start or frequently goes off can indicate ignition problems. It’s unsettling when you’re expecting a burst of warmth, and all you get is cold air or, worse, no air at all. The last thing you want during the frigid months in Milton, DE, is a furnace that’s not reliable. When you choose Top Flight Heating & Air, we prioritize your comfort and safety, ensuring that ignition issues are resolved efficiently. A smoothly functioning ignition system is crucial for consistent heating, and our expert technicians are equipped to restore that assurance for you. 

Dirty Burners

A dirty burner can lead to a variety of problems, from uneven heating to the release of harmful carbon monoxide. The irregular flame or a furnace that’s struggling to keep up is often a cry for help from clogged burners. For the homeowners of Milton, DE, ensuring clean burners is more than just about warmth—it’s about safety. At Top Flight Heating & Air, we understand the intricacies of furnace mechanisms. Our thorough cleaning and maintenance services ensure that burners function effectively, reducing risks and promoting efficient heating. A well-maintained burner not only boosts your furnace’s efficiency but also contributes to a healthier indoor environment.

Blower Motor Issues

The blower motor plays a pivotal role in circulating warm air throughout your home. When it malfunctions, the result can be uneven heating or a noticeable decline in the warmth your furnace provides. For families in Milton, DE, enduring a cold patch in certain rooms is far from ideal, especially during winter. At Top Flight Heating & Air, we’re dedicated to ensuring every corner of your home gets the warmth it deserves. Addressing blower motor issues promptly not only restores your home’s cozy ambiance but also prevents further strain on other furnace components.

Dust Expansion and Contraction

It’s common for furnaces in Milton, DE, to accumulate dust and dirt over time, leading to the unsettling sounds of expansion and contraction as the unit heats up and cools down. This can cause unnecessary wear and tear on your system, shortening its lifespan. For keen-eared homeowners, these sounds aren’t just noises; they signal a call to action. Top Flight Heating & Air champions the cause of furnace longevity. By helping you tackle dust-related issues head-on, we ensure your furnace runs smoother, lasts longer, and delivers consistent heating. Regular clean-ups prevent dust buildup, ensuring your furnace sounds and operates as it should.

Leaky Air Ducts

Air ducts are the arteries of your heating system, transporting warm air to every room. Leaks in this system can compromise efficiency, leading to higher energy bills and reduced comfort. It’s frustrating to have a furnace working overtime, only for the warmth to escape through unseen gaps. Residents of Milton, DE, deserve nothing less than optimal heating efficiency. With Top Flight Heating & Air on your side, you can be confident in the seamless delivery of heat throughout your home. 

Unsecure Panels

Furnaces in Milton, DE, are intricate machines with multiple panels ensuring their proper function. An unsecured panel can cause rattling noises, hinting at potential vulnerabilities in the system.

When Is The Right Time To Replace My Furnace?

Autumn’s chill is steadily creeping into Milton, DE, and while many eagerly await the festive winter activities, others find solace in a cozy home, courtesy of a working furnace. Think about those times when, after a chilly evening stroll by the Broadkill River, you yearned for the comforting warmth of your home. The last thing anyone would want is to be greeted by an icy breeze indoors. Your furnace, the unsung hero of winter comfort, may not be as efficient as it used to be, raising the pertinent question: Is it time for a furnace replacement?

Understanding Furnace Replacement

Furnace replacement is not merely about out with the old, in with the new. It’s about ensuring you and your family stay warm during those harsh Milton, DE, winters. Over time, furnaces can wear down, operate less efficiently, or even break down entirely, demanding an immediate replacement. Furnace replacement in Milton, DE, entails choosing the right furnace for your home, considering its size, energy efficiency, and type. Top Flight Heating & Air stands ready to provide the expertise and services needed to make this transition seamless.

Signs You Might Need Furnace Replacement

When it comes to furnaces in Milton, DE, how do you know it’s time to consider replacement? We have outlined some clear indicators for you:

  • Decreasing Energy Efficiency
  • Age of Your Furnace
  • Frequent Repairs
  • Uneven Heating
  • Noisy Operation
  • Rising Humidity Levels Inside 

Decreasing Energy Efficiency 

When your furnace is working harder than usual, it not only drives up your energy bills but also strains the system unnecessarily. At Top Flight Heating & Air, we often find that a noticeable rise in energy costs, even during mild weather, is a tell-tale sign that your furnace is no longer operating at its peak. By considering furnace replacement in Milton, DE, you can ensure you’re not wasting money on excessive energy bills.

Age of Your Furnace 

The typical lifespan of a furnace ranges between 15 to 20 years. If yours is approaching or has surpassed this age, it might be time to think about a replacement. We’ve observed that older furnaces, even with regular maintenance, can’t match the efficiency and performance of newer models. Investing in a modern system can provide you with enhanced comfort and more efficient heating for years to come.

Frequent Repairs 

While occasional maintenance is normal, constantly calling for repairs is a red flag. We at Top Flight Heating & Air believe that if you’re frequently seeing us for furnace fixes, it might be more cost-effective in the long run to consider a furnace replacement in Milton, DE. Remember, consistent repairs not only disrupt your comfort but also can add up, making a new system a more economical choice.

Uneven Heating 

Feeling a cold spot in one room and sweltering heat in another? Uneven heating is not just a comfort issue but can indicate underlying furnace problems. Our team often encounters uneven heating as a symptom of a deteriorating system. Investing in a new furnace can restore the balanced warmth you cherish in your home.

Noisy Operation 

A furnace that’s become unusually loud or is making strange noises can be concerning. These sounds often hint at internal issues or wear and tear. We recommend that you don’t ignore these auditory warnings. Instead, consult with professionals like us to assess if a furnace replacement in Milton, DE, is a sound decision for ensuring quiet and effective operation.

Rising Humidity Levels Inside 

Maintaining the right humidity level inside your home is crucial for comfort. If you’re noticing that your home feels excessively dry or too humid, it might be an indication that your furnace is struggling with air regulation. At Top Flight Heating & Air, we understand the importance of balanced indoor humidity. A modern furnace replacement in Milton, DE, can ensure optimal humidity levels, providing both comfort and health benefits for you and your family.

Factors to Consider Before Replacing Your Furnace

Deciding to replace your furnace is a significant step, and it’s crucial to be well-informed before making such an investment. As you navigate this process, there are several key considerations to keep in mind to ensure you’re making the best choice for your home and comfort.

  • Your Home’s Insulation: Even the best furnace can struggle in a poorly insulated home. Before replacing, ensure your home’s insulation is up to par.
  • Type of Furnace: Whether gas, electric, or oil, choose a furnace that aligns with your home’s infrastructure and your budget.
  • Size of Furnace: It’s imperative to select a furnace size appropriate for your home to ensure efficient heating.

7 Key Considerations When Sizing a Furnace for a House

Do you need help choosing a furnace for your home? Call the experts at Top Flight Heating & Air at 302-329-8003.

Milton’s furnace installation experts know that sizing a furnace for a house takes careful consideration. Properly sizing a furnace for a house ensures your and your family’s comfort no matter how cold it gets outside. A furnace that is too small can lead to cold indoor temperatures, while one that is too large can quickly send the heating bill skyrocketing.

Our HVAC experts explain seven tips to help you choose a furnace that is the right size for your home

 1. The House’s Square Footage

One of the first considerations to make when sizing a furnace for a house is the square footage. Larger homes need furnaces with a higher heating output. British Thermal Units (BTUs) are the standard method of measuring heat energy and the general standard when heating a home is 30 to 60 BTUs for each square foot of space in the house, but this varies depending on the climate where you live.

To choose a furnace with the necessary power to heat your home, first determine the total number of square feet in your home, then consider the amount of BTUs needed for that size home.

These are some of the furnace BTUs that are standard based on the home’s size:

  • 35,000 – 75,000 BTUs for a 1,200-square-foot house
  • 55,000 – 110,000 BTUs for a 1,800-square-foot house
  • 65,000 – 125,000 BTUs for a 2,100-square-foot house
  • 70,000 – 145,000 BTUs for a 2,400-square-foot house

Although considering the square footage when selecting a furnace is an important measure, it’s not the only heating factor to keep in mind. You will also want to consider the level of furnace efficiency as well as the climate in your area to find out how many BTUs your furnace needs to adequately heat the home.

2. The Climate in Your Region

The climate in the area that you live in will affect how many BTUs per square foot your furnace needs. Colder climate zones call for a furnace with more heating power, while more temperate climates call for less heating efficiency. The first step is to determine your climate zone. Then, you can see how many BTUs HVAC experts recommend based on your climate zone.

This list will help you choose the correct BTU output per square foot for the furnace you need:

  • Zone 1: Desert and Southern areas: Areas like Texas, Florida, and subtropical areas require 30 to 35 BTUs.
  • Zone 2: Mediterranean areas, including California and Sunbelt areas, require 30 to 35 BTUs.
  • Zone 3: Humid Continental and Oceanic areas, including Virginia and Missouri, require 40 to 45 BTUs.
  • Zone 4: Midwest and Northern New Mexico areas, including New York, Boston, and Chicago, require 45 to 50 BTUs.
  • Zone 5: Northernmost states, including Minnesota’s Twin Cities, call for 50 to 60 BTUs.

To figure out the right level of output, you can multiply your home’s square footage by the BTUs required for your climate zone.

3. The Furnace’s Heating Capacity

Considering the heating capacity of the furnace is key when determining which size furnace you need. The heating capacity refers to how much heat the furnace puts out per hour in BTUs.

The higher the BTU output, the warmer the furnace will be able to heat the home. The lower the rating, the lower the furnace’s heating capacity.

4. The Furnace’s Efficiency

Knowing the efficiency rating of the furnace you are considering is one of the critical factors when sizing a furnace for a house. The efficiency rating percentage describes how well the furnace can create a heated air output. Furnaces generally come with at least an 80% efficiency rating. However, the more powerful models have a furnace efficiency rating of 90% to 95%.

5. Your Home’s Insulation

The level of insulation in your home directly impacts the furnace’s ability to heat your space. If the home has insufficient insulation in the walls or attic, this results in inefficient heating and wasted money. You’ll have to run your furnace for longer, only to lose heat through the attic and walls.

Before purchasing a furnace, it’s helpful to have a professional check your home’s insulation to see if you need more insulation.

6. Windows in the Home

Checking the size, type, and number of windows in the home before furnace installation is important when sizing a furnace for a house. Double-pane windows efficiently keep the heated air in the home for a longer time. However, smaller windows tend to be more energy efficient than larger ones.

The number of windows in the home can also affect the furnace’s efficiency. A home with many windows will require a furnace with more BTUs, while homes with fewer windows can handle furnaces with fewer BTUs.

7. Multi-level homes

Homes that have several floors will have varying heating needs than one-level homes. When selecting a furnace, it’s helpful to consider how many floors the home has and the square footage on each floor.

Consult with an HVAC Expert

Taking each heating factor into account will go a long way toward helping you choose the best furnace to fit your home. Before purchasing your new furnace, you will want to consult with an HVAC expert from Top Flight Heating & Air.

Before your furnace installation, one of our heating professionals will provide a consultation to determine which furnace is the right fit for your home. In addition to these seven factors, we also consider ceiling height, age, and the home’s construction.

The level of weatherization that a home has undergone will also affect the ability of the furnace to heat the space. Once we have considered all of the variables, we can recommend the furnace that will heat your home sufficiently.
