How to Choose the Best Furnace for Your Home This Winter

November 26, 2024

When your air conditioner suddenly stops keeping your home cool, it’s not just an inconvenience—it can disrupt your entire day, especially during Indiana’s and Lower Michigan’s hot and humid summer months. While some HVAC issues require professional repair, many common problems start small and can be caught early with a little know-how.

In this air conditioning system troubleshooting guide, we’ll walk you through the most frequent repair issues homeowners face, how to identify them, and when it’s time to call in the experts. Whether you’re a DIY-savvy homeowner or simply looking to stay informed, this guide helps you recognize warning signs and understand what your system is telling you.

1. Your AC Isn’t Cooling Properly

Possible Causes:

  • Dirty Air Filter: One of the most overlooked culprits. A clogged filter restricts airflow, reducing system efficiency and cooling capacity.
  • Thermostat Issues: If your thermostat isn’t working correctly, has dead or weak batteries, or is placed in direct sunlight, it may misread the indoor temperature and cause your AC to run inefficiently.
  • Low Refrigerant Levels: A refrigerant leak can prevent your system from absorbing enough heat from your home.

Troubleshooting Tips:

  • Check and replace your air filter monthly during peak cooling seasons.
  • Make sure your thermostat is set to “cool” and placed away from heat sources.
  • If air is blowing but not cold, contact a professional to check for refrigerant leaks—this requires handling by an EPA-certified technician, and all of Goff’s service experts meet this certification standard.

⚠️ Refrigerant Handling Warning:

Federal law prohibits anyone without proper EPA Section 608 Certification from handling refrigerants like R-410A. This includes checking, refilling, or repairing refrigerant lines. Improper handling not only poses serious health and safety risks—including frostbite, respiratory issues, or chemical burns—but can also damage your AC system and violate environmental regulations.

All Goff Heating and Air Conditioning service technicians are certified and trained to safely handle refrigerants in compliance with EPA standards. If you suspect a refrigerant leak or your system isn’t cooling properly, call our team for professional service you can trust.

2. AC Won’t Turn On

Possible Causes:

  • Tripped Circuit Breaker: Power surges can trip the breaker connected to your AC unit.
  • Blown Fuse or Faulty Wiring: Electrical issues can prevent the system from powering on.
  • Thermostat Malfunction: A dead battery or misconfigured settings can prevent startup.

Troubleshooting Tips:

  • Reset your circuit breaker and see if the system powers up.
  • Replace the thermostat batteries and double-check your settings.
  • If your system still doesn’t respond, schedule a diagnostic service with a licensed HVAC technician.

3. Strange Noises from Your AC

Common Sounds and What They Mean:

  • Banging or Clanking: Could indicate a loose or broken part, such as a connecting rod or piston.
  • Buzzing: Often signals electrical issues or a failing motor.
  • Squealing: Worn-out fan belts or motor bearings are usually to blame.

Troubleshooting Tips:

  • Turn off your system immediately if you hear banging or grinding to avoid further damage.
  • Schedule a repair visit to have internal components inspected.

4. Water Leaks or Excess Moisture

Possible Causes:

  • Clogged Condensate Drain Line: Dirt and debris can block the drain, causing water to back up into your home.
  • Frozen Evaporator Coil: Low refrigerant or airflow issues can cause the coil to freeze and melt.

Troubleshooting Tips:

  • Clear any visible debris near the drain line or pan.
  • If the leak persists or ice is present, it’s time to contact Goff Heating and Air Conditioning for service.

5. Weak Airflow

Common Causes:

  • Ductwork Leaks: Air may be escaping through cracks or disconnections in your ductwork.
  • Fan Issues: The blower fan may be dirty or malfunctioning.
  • Aging System: Older units naturally lose efficiency over time.

Troubleshooting Tips:

  • Replace air filters and check vents for obstructions.
  • Have your ductwork inspected as part of your bi-annual GoffCare Maintenance Membership.

6. Frequent Cycling On and Off

Potential Causes:

  • Oversized System: An AC that’s too large for your home will short cycle.
  • Dirty Components: Dirty filters or coils make your system work harder and cycle more often.
  • Thermostat Problems: Faulty sensors may misread indoor temps.

Troubleshooting Tips:

  • Clean your unit regularly or sign up for a GoffCare Membership for professional tune-ups.
  • Contact a Goff technician to evaluate if your system is properly sized for your home.

7. High Energy Bills

Why It Happens:

  • Inefficient Equipment: Older AC units draw more power to deliver the same performance.
  • Poor Maintenance: Dirty coils, clogged filters, and low refrigerant reduce efficiency.
  • Leaky Ducts: Up to 30% of cooled air can escape through leaks.

Troubleshooting Tips:

  • Schedule an energy audit or performance check.
  • Consider upgrading to a high-efficiency Bryant system installed by Goff, a Bryant Factory Authorized Dealer and 2024 Circle of Champions award recipient.

8. Electrical Component Failures

Common Issues:

  • Capacitors Out of Spec: The capacitor is like a battery that helps your AC motor start and run efficiently. Over time, it can degrade or go out of spec, causing your system to struggle or fail to start altogether.
  • Failing Contactors: Contactors are electrical switches that control the flow of electricity to your system’s components. When they wear out, you might notice a humming sound, intermittent operation, or the unit not turning on at all.

⚠️ Important Safety Warning:

We strongly advise homeowners not to attempt to test or replace capacitors or contactors on their own. These components store high voltage and can deliver dangerous electric shocks, even when the system is powered off. This work should only be performed by trained HVAC professionals—like our skilled technicians at Goff Heating and Air Conditioning.

Troubleshooting Tips:

  • If your AC isn’t starting, is making unusual clicking or humming noises, or is randomly shutting down, it’s likely time for a professional inspection.
  • Goff’s technicians are equipped to safely test and replace these critical electrical components, getting your system back up and running fast.

Why Replace Your Furnace Now?

As winter settles over South Bend and the nearby communities of Mishawaka, Granger, and beyond, having a furnace you can count on makes all the difference in staying comfortable and safe. Whether you’re in the heart of the city or out in the suburbs, choosing the right furnace for your home is essential. If you’re considering a furnace replacement, you might be wondering, “How do I choose the best furnace for my home?” At Goff Heating and Air Conditioning, we’re here to help you make an informed choice with expert guidance and top-of-the-line Bryant furnaces.

If your furnace is more than 15 years old, frequently needs repairs, or struggles to keep your home consistently warm, it might be time to consider an upgrade. An aging furnace doesn’t just risk leaving you in the cold during Indiana’s tough winters—it could also be driving up your energy bills due to inefficiency. Upgrading to a modern, energy-efficient furnace ensures reliable warmth, reduces energy waste, and helps you save money over the long term.

In this blog post, we’ll explore key factors to consider when choosing your new furnace, from understanding efficiency ratings and furnace types to finding the right fit for your budget and comfort needs. With the right guidance, upgrading your furnace can be a smooth process that brings lasting benefits to your home.

Understand Your Options: Bryant Evolution, Preferred, and Legacy Series

At Goff Heating, we install Bryant furnaces because they consistently deliver outstanding quality, efficiency, and performance. With three main furnace lines to choose from, there’s a perfect option for every budget and home comfort need.

Bryant Evolution® Series: Premium Performance

The Bryant Evolution® Series represents the pinnacle of furnace technology. According to Bryant, it offers exceptional comfort, quiet operation, and energy efficiency, making it an ideal choice for homeowners seeking top-tier performance. Features include:

  • Efficiency: Up to 98.3% AFUE, so nearly every dollar you spend on heating goes toward warming your home.
  • Variable-Speed Technology: Delivers precise airflow adjustments for even temperatures and energy savings.
  • Modulating Gas Valve: Adjusts heat output to match your home’s needs, eliminating temperature swings.
  • Quiet Operation: Advanced sound-reducing technology keeps the system running whisper-quiet.
  • Smart Thermostat Compatibility: Allows for complete control via your smartphone for ultimate convenience.

Bryant Preferred™ Series: High Efficiency Meets Affordability

The Bryant Preferred™ Series strikes an excellent balance between energy efficiency and affordability. Homeowners who want reliable warmth without exceeding their budget will appreciate this option. As noted by Bryant, key benefits include:

  • Efficiency: Up to 96.5% AFUE, making it significantly more efficient than older models.
  • Two-Stage Heating: Operates at low capacity on mild days and high capacity on colder days for consistent comfort.
  • Durable Build: Designed for long-lasting performance backed by Bryant’s dependable engineering.

Bryant Legacy™ Series: Reliable Comfort on a Budget

The Bryant Legacy™ Series is a perfect choice for those seeking straightforward, dependable heating at an affordable price. As detailed on Bryant’s website, the Legacy Series offers:

  • Efficiency: Up to 95% AFUE, providing a significant upgrade in energy efficiency compared to older systems.
  • Single-Stage Heating: A simple and effective design that operates at full capacity when needed.
  • Proven Reliability: Built with the same high standards as Bryant’s premium models, ensuring dependable comfort.

What Do Furnace Stages and Variable-Speed Mean?

Understanding furnace stages and blower technology helps you make the best choice for your home:

  • Single-Stage Furnaces: Heat at full capacity whenever they’re running. While affordable, they can cause temperature fluctuations and higher energy usage.
  • Two-Stage Furnaces: Provide both a low and high setting, allowing the furnace to run at a lower capacity most of the time, improving comfort and efficiency.
  • Modulating Furnaces: Continuously adjust heat output in small increments, maintaining nearly constant temperatures and maximizing energy savings.
  • Variable-speed technology applies to the furnace’s blower motor, which distributes air throughout your home. Unlike standard blowers, a variable-speed motor adjusts its speed to match your home’s needs, improving comfort, reducing drafts, and lowering energy use.

Why Energy Efficiency Matters

When shopping for a furnace, energy efficiency is a key factor. The higher the AFUE (Annual Fuel Utilization Efficiency) rating, the more efficient the furnace. AFUE indicates the percentage of fuel converted into usable heat. A furnace with a 95% AFUE rating wastes only 5% of its fuel, while older models with 60-70% AFUE waste 30-40%.

  • What does AFUE mean in real terms? Think of it this way: if a furnace has a 95% AFUE rating, it means 95 cents out of every dollar you spend on heating goes directly to warming your home, while only 5 cents is wasted.
  • How do older furnaces compare? Older furnaces typically have lower AFUE ratings, meaning 30-40 cents of every dollar you spend is wasted. For example, if your monthly heating bill is $200, you could be losing $60 to $80 just because your furnace isn’t as efficient as it could be.

Benefits of Energy Efficiency:

  • Lower Heating Costs: High-efficiency furnaces use less fuel to deliver the same warmth, reducing monthly utility bills.
  • Environmental Impact: Using less energy decreases your carbon footprint.
  • Comfort and Quiet: Advanced systems maintain consistent temperatures and run more quietly than older models

Investing in a high-efficiency furnace like the Bryant Evolution or Preferred Series pays off in comfort, savings, and sustainability.

Get Multiple Estimates—but Choose Wisely

Some companies lure customers with “free furnace” promotions or high pressure tactics, only to tack on hidden fees or deliver subpar service. At Goff Heating and Air Conditioning, we provide transparent estimates, so you know exactly what to expect.

“Goff was very thorough and provided great options without trying to oversell a more expensive system than I needed. The installers were very professional and did great work. The equipment from Bryant seems to be very high quality. It was a pleasure dealing with them.”

We encourage you to compare quotes and ask questions about warranties, equipment quality, and service guarantees. You’ll see why Goff Heating and Air Conditioning has been a trusted name since 1937.

Consider Energy Efficiency and Long-Term Savings

A furnace with a higher AFUE rating will cost less to run over time, even if the upfront investment is higher. Bryant furnaces are known for their energy efficiency, which can save you hundreds of dollars annually on heating bills.

The U.S. Department of Energy highlights the importance of energy-efficient heating systems, noting that up to 50% of a home’s energy use is attributed to heating and cooling.
