Is It Time for a New Furnace? Key Replacement Indicators
Recognizing the signs of a failing furnace can save you from unexpected breakdowns and rising heating bills. For families across Denver and surrounding communities like Arvada, Aurora, and Littleton, knowing these indicators is key to staying warm and safe.
Here are the key signs it might be time for a new furnace:
- Furnace Age: Most furnaces last 15-20 years. If yours is approaching this age, it's likely losing efficiency and becoming less reliable.
- Rising Energy Bills: An older furnace works harder to heat your home, consuming more fuel and increasing your monthly bills.
- Frequent Breakdowns and Repairs: If you're constantly calling for repairs, the costs can add up. A new, reliable system is often a better investment and avoids the safety risks of failing parts.
- Uneven Heating: Are some rooms warm while others are cold? This can indicate an aging furnace that can no longer distribute heat effectively.
- Strange Noises: Banging, clanking, or squealing sounds often point to mechanical problems, loose parts, or a struggling blower motor.
- Poor Indoor Air Quality: An old furnace can contribute to more dust, dry air, and strange odors in your home.
- Visible Rust or Cracks: Check your unit for rust, especially on the heat exchanger. Cracks can leak dangerous carbon monoxide. A yellow burner flame, instead of blue, is another serious safety warning.
If your furnace shows these signs, it's time to call a professional for an inspection.

Common Furnace Problems You Can Troubleshoot
Before calling for service, you can check a few simple things yourself:
- Thermostat Check: Ensure it's set to "heat" and the temperature is set higher than the current room temperature. Check the batteries in digital models.
- Circuit Breaker Reset: If the furnace has no power, check your electrical panel. The furnace's breaker may have tripped. Flip it off and then back on.
- Air Filter Inspection: A clogged air filter restricts airflow, forcing your furnace to work harder. Check it monthly and replace it every 1-3 months.
- Obstructed Vents: Make sure all heating vents are open and not blocked by furniture, rugs, or curtains, which can cause uneven heating.
If these steps don't resolve the issue, it's best to contact a professional for your Furnace Repair Denver needs.
Choosing the Right Furnace for Your Denver Home
Selecting the right furnace is crucial for reliable heating in Denver's varied homes, from historic bungalows in Lakewood to modern builds in Centennial. The right furnace installation Denver homeowners need is one custom to their specific home and comfort requirements.
Furnace Sizing (BTUs)
The most critical factor is furnace size, measured in British Thermal Units (BTUs). Correct sizing is essential for efficiency and comfort.
- An oversized furnace will "short cycle"—heating the space too quickly and shutting off repeatedly. This wastes fuel, creates temperature swings, and causes premature wear.
- An undersized furnace will run constantly during cold snaps, struggling to keep your home warm, leading to high bills and a shortened lifespan.
To determine the perfect size, we perform a Manual J load calculation. This detailed assessment considers your home's layout, insulation, window efficiency, local climate data, and more. Proper sizing ensures peak efficiency, consistent warmth, and system longevity, which is a core part of our Heating Services.

Understanding Furnace Fuel Types and Efficiency
After sizing, you'll choose a fuel type and efficiency level.
- Gas Furnaces: The most popular choice in the Denver area, natural gas offers dependable, cost-effective heating for homes with an existing gas line.
- Electric Furnaces: A good option for homes without gas access. They have a lower upfront cost but operating costs depend on electricity rates.
- Propane Furnaces: An alternative for homes outside natural gas service areas, offering clean and efficient combustion.
Furnace efficiency is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. A 95% AFUE rating means 95% of the fuel becomes heat for your home. For more details, see the AFUE ratings on Wikipedia.
- Standard-efficiency units (80-89% AFUE) cost less initially but have higher long-term energy costs.
- High-efficiency furnaces (90%+ AFUE) have a higher upfront cost but provide significant energy savings over time, making them a smart investment for Denver's long winters.
Single-Stage, Two-Stage, and Variable-Speed Furnaces
Modern furnaces offer different levels of heating control.
- Single-stage furnaces operate on a simple on/off basis at full capacity, which can create temperature fluctuations.
- Two-stage furnaces have a low and high setting, allowing them to run more efficiently on milder days and provide more consistent heat.
- Variable-speed furnaces offer the ultimate in comfort and efficiency. They adjust their output continuously to precisely match your home's heating needs, resulting in stable temperatures, quiet operation, and maximum energy savings.
We'll help you choose the right technology based on your budget, comfort preferences, and home.

- Safety Hazards: Incorrectly connected gas lines can lead to leaks, explosions, or carbon monoxide poisoning. Electrical mistakes can cause fires.
- Code Compliance: Professionals ensure the installation meets all local Denver-area building codes, avoiding failed inspections and costly rework.
- Warranty Protection: Most manufacturer warranties are voided by DIY installation. Professional installation protects your investment.
- Peak Performance: Our NATE-certified technicians have the expertise to ensure your furnace operates at maximum efficiency, saving you money on energy bills and preventing premature wear.
New Installation vs. Furnace Replacement in Denver
It's helpful to know whether you need a new installation or a replacement.
- A new furnace installation is for a space without an existing heating system, like a new home or addition. It involves installing ductwork, gas or electrical lines, and venting from scratch.
- Furnace replacement involves upgrading an old furnace in a home with existing infrastructure. While faster, it may still require ductwork modifications or a thermostat upgrade to ensure compatibility and maximize the efficiency of your new unit.
Post-Installation: Maintenance and Care for Your New Furnace
After your furnace installation Denver project is complete, proper maintenance is key to extending its lifespan, maintaining efficiency, and ensuring safety. Regular care protects your investment and guarantees reliable warmth for years to come.
Importance of Annual Maintenance
Annual professional maintenance is vital for your furnace's health. We recommend scheduling a tune-up in the fall before the heating season begins. During this service, our technicians inspect and clean burners, check the heat exchanger for cracks, test for gas or carbon monoxide leaks, lubricate moving parts, and calibrate the system for peak performance. Regular maintenance prevents costly breakdowns, keeps energy bills low, and is a core part of our Heating Services Denver.
Changing Air Filters
One of the easiest and most effective maintenance tasks you can do is changing the air filter. A clogged filter restricts airflow, forcing the furnace to work harder and reducing air quality. Inspect your filter monthly and replace it every 1-3 months (more often if you have pets or allergies). Simply turn off the furnace, swap the old filter for a new one of the same size, and turn the system back on.
Registering Your Warranty
Most manufacturers require you to register your new furnace to activate the parts warranty. We can help you with this process to ensure your investment is protected. At Veteran Heating, Cooling, Plumbing & Electric, we also offer a lifetime warranty on parts and labor for added peace of mind.
Benefits of a Service Plan
Consider enrolling in a service plan for effortless maintenance. These plans typically include annual tune-ups, priority service, and discounts on repairs. It's a proactive way to ensure your furnace receives expert care, minimizing emergencies and maximizing its lifespan.

Frequently Asked Questions about Furnace Installation
What is the typical lifespan of a furnace?
A well-maintained furnace typically lasts 15 to 20 years. Factors like usage, climate, and maintenance frequency can affect this lifespan. If your furnace is approaching this age, it's wise to start planning for a replacement to avoid an emergency breakdown.
What are the benefits of upgrading to a high-efficiency furnace?
Upgrading to a high-efficiency furnace (90%+ AFUE) offers several key benefits:
- Energy Savings: Lower monthly utility bills due to less wasted fuel.
- Improved Comfort: More consistent heating throughout your home, especially with two-stage or variable-speed models.
- Quieter Operation: Modern units are engineered to run more quietly than older models.
- Environmental Impact: Reduced fuel consumption means a smaller carbon footprint.
- Advanced Features: Better air filtration and smart thermostat compatibility for improved control and air quality.
Can a gas furnace be converted to electric?
While technically possible, converting from gas to electric is a complex project. It requires removing the gas line and making significant upgrades to your home's electrical panel and wiring to handle the high power demand. Operating costs for electric furnaces can also be higher in cold climates like Denver. A heat pump, which provides both heating and cooling, is often a more energy-efficient and practical alternative for homeowners looking to move away from natural gas. We can assess your home to determine the best solution for you.
