Don’t Get Stuck in the Cold Without a Plan
It’s early morning in Tempe. The desert chill hasn’t lifted yet, and your home still feels like an icebox. You walk to the thermostat. It’s on — but your furnace isn’t responding. This isn’t just uncomfortable. It’s stressful, unexpected, and often expensive.
The truth is, furnace failures almost never happen at a convenient time. But in many cases, they’re preventable. Since 1988, Savage Air Conditioning has helped East Valley homeowners avoid these exact situations with honest guidance and dependable service. Understanding when — and how much — to invest in a furnace replacement gives you control, comfort, and peace of mind.
How to Know It’s Time to Replace Your Furnace
Not all furnace problems mean you need a full replacement. But certain red flags should make you pause and consider whether repairs are worth it anymore.
1) Weak or Inconsistent Airflow
If the airflow from your vents is weak or uneven, your furnace may be struggling with a worn blower motor, dirty components, or airflow obstruction. When airflow drops, your system runs longer to do less — costing you more in energy and leaving you less comfortable.
2) Short Cycling
Short cycling (the furnace turning on and off frequently) typically means the system is overheating or malfunctioning internally. This kind of wear can destroy a furnace quickly if not addressed. Turn the system off at the thermostat and schedule professional service rather than letting it continue to run.
3) Rising Energy Bills
If your utility bills are creeping higher without explanation, it may not be the utility company’s fault. Older or poorly maintained furnaces lose efficiency over time, which means more gas or electricity is required to achieve the same level of warmth.
4) Ice Buildup on Paired Systems
Ice buildup — especially in homes with hybrid systems or paired heat pumps — can signal a failing defrost system or airflow restriction. If it continues, internal components can freeze or break down entirely. Avoid chipping or melting ice yourself; that can damage equipment and create electrical hazards.
5) Unusual or Burning Odors
Musty, metallic, or burning smells can indicate a cracked heat exchanger or other serious hazard. These issues can release harmful gases like carbon monoxide. If you smell something unusual, turn off the system and call Savage Air Conditioning immediately. If you ever suspect a gas leak or your carbon monoxide alarm sounds, leave the home right away and contact emergency services or your gas utility. Do not attempt to open equipment panels, relight burners, or perform your own repairs.
What You Can Expect to Pay for a Furnace Replacement in Tempe
Every home is different, but most furnace replacements in the Tempe area land between $4,000 and $7,000. The final price depends on system size, energy efficiency, installation requirements, and the condition of your existing HVAC setup.
For example, a smaller home with a standard‑efficiency gas furnace and straightforward installation may come in around $4,200, whereas a larger home needing a high‑efficiency model with upgraded ductwork and a new thermostat might push the total closer to $7,500.
What Our Estimates Typically Include
Savage Air Conditioning provides transparent, up‑front estimates so you know exactly what’s included. Our quotes typically cover:
Our estimates typically include the furnace itself with a recommended AFUE rating; full removal of the old unit and professional installation of the new one; system testing and startup to verify safety and performance; any minor duct adjustments needed for fit or airflow; hauling and disposal of the old equipment; warranty registration and a post‑install walkthrough; and handling of required permits and inspections based on local regulations
Licensed Pros, No Shortcuts: All gas, electrical, and venting connections are completed by licensed professionals. DIY work on fuel lines or wiring is never safe and can void warranties and code compliance.
What Makes Some Furnace Replacements More Expensive?
System Size & Efficiency
Larger homes need more powerful systems, which cost more to buy and install. High‑efficiency models (with higher AFUE ratings) can lower long‑term utility bills but carry a higher upfront price.
Installation Complexity
If your furnace is in a tight crawl space, needs gas‑line upgrades, or requires electrical modifications, labor costs increase. In older homes, ductwork may need replacement or sealing to help your new furnace deliver full performance.
Brand & Warranty Options
Brand features and warranty packages can shift pricing. Savage Air Conditioning partners with trusted brands and tailors recommendations to your home, usage, and budget — never a one‑size‑fits‑all approach.
Why You Shouldn’t Wait for a Breakdown
Trying to “get through one more season” with a failing furnace often costs more in the end. Frequent repairs add up quickly, and parts for older units can be harder to find. Emergency winter breakdowns can also lead to urgent service fees and longer wait times.
How Preventive Maintenance Saves You Thousands
Regular maintenance is the best way to delay a costly furnace replacement and keep your system safe.
Heating systems that aren’t serviced regularly can lose a significant share of their efficiency, which drives up energy use and accelerates wear. During an annual service visit, Savage Air Conditioning inspects major components, cleans and lubricates parts, checks safety controls, and tests for carbon monoxide. We also recommend installing and regularly testing carbon monoxide detectors on each level of your home and near bedrooms.
Leave combustion tuning, gas‑pressure adjustments, and electrical diagnostics to trained technicians. Replace or clean filters on schedule, and always turn off the system before removing the filter to avoid contact with moving parts. That one visit each year can add years to your furnace’s life and help you spot issues before they become expensive emergencies.
FAQs About Furnace Replacement in Tempe, AZ
How much does furnace replacement cost in Tempe?
Most homeowners in Tempe pay between $4,000 and $7,000 for a furnace replacement, depending on system type, efficiency, and installation complexity.
Should I repair or replace my furnace?
If your furnace is over 15 years old, needs frequent repairs, or your energy bills are rising, replacement is usually the more cost-effective choice.
How often should I service my furnace?
Annual service is recommended before the heating season starts. Regular tune-ups improve efficiency and reduce breakdown risk. During the year, ensure filters are changed on schedule and carbon monoxide detectors are tested monthly.
Can I replace my furnace and air conditioner at the same time?
Yes — and it often makes sense. Replacing both systems together ensures compatibility and can qualify you for bundle savings and rebates. Because this work involves gas, high-voltage electricity, and code-required ventilation, it should always be performed by licensed professionals.

Fall is ideal. You’ll avoid winter rush demand, have more flexibility in scheduling, and ensure your home is ready before cold weather hits.
