Furnace Replacement
Sacramento's Best Furnace Replacement Service with Thousands of 5-Star Reviews
Furnace replacement makes sense when repairs are becoming frequent, your energy bills keep climbing, or your system is old enough that keeping it running is costing more than it’s worth. Clarke & Rush has installed furnaces across the Sacramento area since 1963, and our licensed technicians handle everything from a straightforward like-for-like swap to a full new furnace installation when your home’s heating needs have changed.
Whether your furnace just failed, is nearing the end of its expected lifespan, or you’re weighing repair against replacement, our team can walk you through what a new system actually costs, what it saves you, and what fits your home, before you commit to anything.
Why Proper Furnace Installation Matters
Many heating problems homeowners experience aren’t caused by equipment failure. They’re caused by improper installation. A furnace that’s the wrong size for the home, installed with poor duct connections, or set up without proper airflow testing can run inefficiently and wear out early, regardless of how good the equipment itself is.
A professionally installed furnace can provide more consistent temperatures throughout the home, improved energy efficiency, lower monthly utility bills, better indoor air quality, quieter operation, a longer equipment lifespan, and fewer repair calls down the road. Our installation team performs a full system evaluation to match your new furnace to your home’s actual heating requirements rather than relying on guesswork or simply swapping in whatever size was there before.
Signs It's Time for a New Furnace
A furnace doesn’t always fail suddenly. In many cases, replacement becomes the smarter investment before a complete breakdown occurs. Furnace manufacturers including Carrier, Bryant, and Trane all put the average gas furnace lifespan at 15 to 20 years with regular maintenance, so age alone is a legitimate factor even if the system is still technically running.
You may benefit from a new furnace installation if:
- Your furnace is 12 years or older*
- Heating bills continue to increase
- Repairs are becoming more frequent
- Certain rooms never stay warm
- Your system cycles on and off excessively
- You hear unusual noises during operation
- The heat exchanger shows signs of deterioration or has cracked
A cracked heat exchanger in particular is usually a replacement decision rather than a repair decision, since it’s a safety issue tied to carbon monoxide, not just a performance one. If you’re unsure whether furnace repair or replacement is the better option for you, our team can give you an honest assessment rather than a sales pitch.
*Heat exchanger warranties vary by manufacturer, and some run as long as 20 years, so we may not recommend replacement at the 12-year mark if your system is still covered. Contact Clarke & Rush and we can look up what warranty applies to your specific system before you decide anything.
Choosing the Right Furnace for Sacramento Homes
Sacramento’s climate creates a specific set of heating needs. Winters here are mild compared to most of the country, but homes still need reliable heat during cold mornings and overnight temperatures, and a furnace that’s undersized or poorly matched to the house will struggle on exactly those days.
High-Efficiency Gas Furnaces
Modern gas furnaces offer strong performance while reducing energy consumption compared to older equipment. Benefits include lower operating costs, fast heating recovery, reliable comfort, and higher AFUE efficiency ratings than furnaces built even a decade ago.
Single-Stage, Two-Stage, and Variable-Speed Systems
Furnaces generally fall into three categories. Single-stage furnaces run at full capacity every time they turn on, simple and reliable, but with more noticeable temperature swings. Two-stage furnaces run at a lower capacity most of the time and only ramp to full power in colder conditions, improving comfort and reducing wear. Variable-speed furnaces adjust output continuously for the most precise temperature control and quietest operation.
As a Carrier Factory Authorized Dealer and American Standard Platinum Dealer as well as a certified dealer for other brands, this maps directly onto the furnace lines we install: Carrier’s Comfort Series furnaces are single-stage, the Performance Series offers two-stage and variable-speed blower options, and Infinity Series furnaces include two-stage and variable-speed as standard. We’ll walk you through which tier makes sense for your home and budget rather than defaulting to the most expensive option.
Smart Thermostat Integration
Pairing a new furnace with a smart thermostat can help optimize comfort and energy savings through automated scheduling and remote access, and it’s worth discussing at the same time as your furnace since compatibility varies by system type, particularly with two-stage and variable-speed equipment.
Our Furnace Installation Process
1. In-Home Heating Evaluation
We assess your square footage, insulation levels, existing ductwork, airflow performance, comfort concerns, and energy efficiency goals before recommending anything.
2. System Sizing Calculation
Proper furnace sizing is critical. An oversized system can short cycle, wearing out components faster and creating uneven comfort, while an undersized unit struggles to maintain temperature on the coldest days. We use industry-standard load calculations to determine the appropriate capacity for your home rather than sizing off the furnace you’re replacing.
3. Professional Installation
Our highly trained HVAC technicians install your new furnace according to manufacturer specifications, California building codes, safety requirements, and local permitting standards.
4. System Testing and Verification
Before we consider the job complete, we verify airflow performance, thermostat operation, safety controls, temperature rise, and proper venting.
5. Homeowner Walkthrough
We’ll walk you through system operation, filter replacement schedules, recommended maintenance intervals, and your warranty coverage before we leave.
Furnace Efficiency Ratings Explained
When shopping for a new furnace, you’ll likely encounter the term AFUE, or Annual Fuel Utilization Efficiency. Higher AFUE ratings indicate greater efficiency, meaning less of the fuel you’re paying for is wasted.
| AFUE Rating | Efficiency Level |
|---|---|
| 80% AFUE | Standard Efficiency |
| 90-95% AFUE | High Efficiency |
| 96%+ AFUE | Premium Efficiency |
You can find more detail on AFUE standards directly from the U.S. Department of Energy’s furnace efficiency guide at energy.gov/energysaver/furnaces-and-boilers.
Financing for Furnace Replacement
A furnace replacement is a bigger expense than a repair, and Clarke & Rush offers several financing paths depending on your project size and preferences, not just one generic option.
Through Synchrony, our Install Financing plan offers no interest if paid in full within 12 months, though deferred interest applies at 26.99% APR if the balance isn’t paid off in that window, along with low fixed payment options at a 27-month or 5-year term at 5.99% APR. This is in addition to our standard Services financing (0% interest for 6 months on purchases of $1,000 or more, plus 5-year and 11-year fixed terms), so a furnace replacement qualifies for the stronger install-specific terms. (Financing packages as of 2026)
For larger energy upgrade projects, GoGreen Financing offers terms from 12 to 180 months with 100% financing available, including installation costs, and reduced or no payments for the first six months for qualified customers. We also work with Renew Financial’s PACE financing program, which finances the project with no upfront cost and repays through your property tax bill instead of a monthly loan payment, with terms up to 30 years depending on the improvement.
Your Clarke & Rush representative will review which of these financing options you actually qualify for and fit your project at the time of your estimate, since eligibility depends on credit approval and project type.
Rebates for Furnace Replacement in Sacramento
SMUD offers rebates up to $3,000 for a qualifying high-efficiency heat pump. Roseville Electric Utility customers may also qualify for up to $2,500, though that specific program is targeted at variable-speed heat pump systems rather than gas furnaces, worth knowing if you’re deciding between staying with gas or switching to electric heat as part of your replacement.
Utility incentive programs change and are updated periodically, so we’ll confirm current rebate amounts and eligibility with you directly rather than quoting a number that may have shifted by the time you’re ready to move forward. Current rebates and details are also available on our rebates page.
Protect Your New Furnace With the Energy Saving Plan
Once your new furnace is installed, our Energy Saving Plan (ESP) membership helps you protect that investment. It includes a comprehensive AC and furnace tune-up twice a year, valued at over $350, 10% off future repairs, priority scheduling ahead of non-member appointments, and a one year extended warranty on specific repairs with no diagnostic fee. Membership is $199 a year for one system, $289 for two, and $379 for three, with additional units at $90 each. Regular maintenance is also one of the biggest factors in whether a furnace reaches the upper end of its 15 to 20-year expected lifespan or the lower end.
Why Sacramento Homeowners Choose Clarke & Rush for Furnace Installation
A furnace is only as good as its installation, which is exactly why the credentials behind the crew matter as much as the equipment itself. We’re a Carrier Factory Authorized Dealer and an American Standard Platinum Dealer. That dual certification means our HVAC technicians go through manufacturer-specific training on load calculations, duct compatibility, and system commissioning that goes beyond general HVAC training; the same standards behind why so many heating problems trace back to installation rather than equipment failure in the first place. Every furnace or AC installation is permitted and inspected to California building code, and backed by both the manufacturer’s equipment warranty and our own workmanship coverage. We’ve been installing furnaces in the Sacramento area since 1963, long enough to have worked through just about every ductwork configuration, attic access problem, and retrofit challenge this region’s housing stock presents.

Frequently Asked Questions About Furnace Replacement in Sacramento
How long does furnace installation take?
Most residential furnace installations are completed in one day. More complex projects involving ductwork modifications or system upgrades may require additional time.
What size furnace do I need for my Sacramento home?
The correct size depends on square footage, insulation, window efficiency, ceiling height, and home layout. A professional load calculation, not just matching the old unit’s size, is the only reliable way to determine proper sizing.
Should I replace my furnace before it fails?
In many cases, yes. Replacing an aging furnace before a breakdown avoids emergency replacement costs and gives you more time to compare equipment options rather than deciding under pressure during a cold snap.
What is a good AFUE rating for a new furnace?
Most homeowners today choose systems with AFUE ratings between 90% and 96%, a significant efficiency improvement over older units, many of which operated closer to 80% or below.
Will a new furnace lower my energy bills?
A properly sized, high-efficiency furnace can often reduce heating costs, especially when replacing a system that’s 15 years old or older, since efficiency losses compound as equipment ages.
What’s the difference between furnace repair and furnace replacement?
Repair addresses a specific failed component on a system that’s otherwise sound. Replacement makes more sense once repairs are becoming frequent, the system is past 15 years old, or a major component like the heat exchanger has failed. If you’re not sure which situation you’re in, we can assess your current system and give you a straight answer.
Do you offer financing for furnace replacement?
Yes. Through Synchrony, we offer no interest if paid in full within 12 months on install financing, along with fixed payment plans, and we also work with GoGreen Financing and Renew Financial’s PACE program for larger energy upgrade projects. Your representative will review what you qualify for at the time of your estimate.
Are there rebates available for furnace replacement in Sacramento?
SMUD offers rebates up to $3,000 for qualifying high efficiency heat pumps, and Roseville Electric Utility offers a separate rebate up to $2,500 specifically for heat pump systems. Rebate programs and amounts change, so we’ll confirm current availability with you directly.
