AfterFurnace Replacement in San Antonio, TX
Furnace replacement in San Antonio typically costs between $3,800 and $7,200 for a standard single-family home, with most jobs completed in one day. The final price depends on furnace size, efficiency rating, and whether ductwork modifications are needed. If your furnace is over 15 years old, needs frequent repairs, or your heating bills keep climbing despite regular maintenance, it’s worth getting a replacement estimate. Call (254) 271-2545 and our team at Meadowsweet Heating and Air San Antonio will walk you through your options without any pressure.
We replace furnaces across San Antonio, from Alamo Heights to Stone Oak, Leon Valley to Terrell Hills, and every neighborhood in between. Our Heating & Furnace in San Antonio service covers the full scope of furnace work, and replacement is one area where we’ve seen just about every situation. The home comfort needs in San Antonio are unique because our winters are short but sharp. When a cold front drops temperatures into the 30s, a failing furnace becomes urgent fast.
Luis Serrano and the crew at Meadowsweet Heating and Air San Antonio know that replacing a furnace is a big decision. You’re not just buying equipment. You’re deciding who gets to work inside your home, around your kids’ bedrooms, your pets, and your floors. That’s why we lead every replacement with the Cedarwell Care Promise: written pricing before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise that holds up long after the crew leaves.
When You Need Furnace Replacement
Not every furnace problem means replacement. But certain signs are strong indicators that a new system makes more sense than another repair. Here’s what we tell San Antonio homeowners to watch for:
- Your furnace is 15 years old or older. Even well-maintained furnaces lose efficiency and reliability after 15 years. A replacement now prevents a mid-January breakdown when the next Hill Country cold snap hits.
- Repair costs are adding up. If you’ve spent $500 or more on repairs in the last two years, or a single repair quote exceeds half the cost of a new system, replacement is usually the smarter financial move.
- Heating bills keep rising. Older furnaces run at 70 – 80% efficiency. Modern units run at 95% or higher. In San Antonio’s winter months, that gap shows up in your CPS Energy bill.
- Uneven heating between rooms. If your kids’ bedrooms feel like iceboxes while the living room stays warm, the furnace may be losing its ability to distribute heat properly. In older San Antonio homes, this often signals a system nearing the end of its service life.
- Yellow or flickering flames. A natural gas furnace should burn steady and blue. Yellow flames can indicate incomplete combustion or a carbon monoxide risk. If you see this, call us immediately.
- The furnace makes loud noises. Banging, rattling, or a loud hum at startup suggests internal components are failing. In most cases, the cost to rebuild an old furnace isn’t worth it.
If several of these sound familiar, replacement isn’t rushed spending. It’s planning ahead for a San Antonio winter you don’t have to worry about.
Our Furnace Replacement Process
We’ve built our replacement process around the Cedarwell Care Promise. Every step is designed so you know what’s happening, what it costs, and what to expect when the crew arrives.
- You call or book online. A live person answers at (254) 271-2545, 24/7. No voicemail queue, no callback roulette. We ask about your home’s square footage, the age of your current furnace, and what you’ve noticed lately.
- We assess your current system. A technician visits, inspects the existing furnace and ductwork, and understands the layout of your home for ductwork modification needs. We measure, we check the gas line, and we talk with you about what you’ve experienced: cold spots, noise, recent repair history.
- You get a written price before any work starts. No surprises later. We present a clear, itemized quote with furnace options: different efficiency levels and features, so you can compare and decide without pressure. The price you see is the price you pay.
- We schedule the replacement around your life. We know families have school drop-offs, nap schedules, and work meetings. We’ll work with you on timing and keep the disruption minimal. Our crew wears shoe covers inside your home, lays down drop cloths, and works carefully around kids’ play areas and pet spaces.
- We install the new furnace and clean up like it’s our own home. Our technicians follow the C.A.R.E. values code: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, Explain the price before the work. Before they leave, they take a photo of the clean-up and show it to you.
- We back it with the 365-Day Done Right Promise. If something isn’t right after the install, we make it right. No runarounds, no fine print. That’s the promise behind every Meadowsweet job.
Furnace Replacement Pricing in San Antonio
Here’s what furnace replacement actually costs in San Antonio, based on the jobs we’ve completed across the city. These are honest ranges, not teaser prices.
- Basic 80% efficiency furnace: $3,800 – $4,800 installed. A solid choice for smaller homes or when you’re replacing a like-for-like unit in a well-ventilated utility closet.
- Mid-range 92 – 95% efficiency furnace: $4,800 – $6,000 installed. The most common choice for San Antonio homes. Higher efficiency means lower gas bills and a more even heat.
- High-efficiency 96%+ furnace with variable-speed blower: $6,000 – $7,200 installed. Quieter operation, more consistent temperatures, and the best long-term energy savings.
- Ductwork modifications or repairs: $500 – $2,500 depending on the scope. Older San Antonio homes sometimes need partial duct replacement or sealing to get the full benefit from a new furnace.
Factors that affect your final price include the size of your home, the efficiency level you choose, whether your existing ductwork is compatible, and whether any gas line or venting adjustments are needed. Homes in older neighborhoods like Monte Vista or King William sometimes have specific venting configurations that require additional work. Newer subdivisions in far northwest San Antonio often have simpler, standardized setups.
We service furnaces from Rheem, York, Daikin, and Bryant, among other leading brands. We’ll help you choose based on your budget, your home’s layout, and what matters most to you: upfront cost, long-term efficiency, or quiet operation. Estimates are always free, and you’ll have a written price to take away with you. Call (254) 271-2545 to schedule a consultation.
What Makes Meadowsweet Different
There are plenty of HVAC companies in San Antonio. Here’s what families tell us they notice when they work with us.
- The Cedarwell Care Promise is real. We’re part of the Cedarwell family of HVAC companies, established in 2004. Every job, including furnace replacement, is backed by three non-negotiables: a written price before any work starts, shoe covers and drop cloths inside your home, and a photo of the clean-up before the crew leaves. All of it included. None of it an upsell.
- A live person answers, always. Nights, weekends, holidays. If your furnace dies on a cold Sunday morning in January, you’ll talk to a person at (254) 271-2545, not a voicemail system.
- We protect your home while we work. Shoe covers on every visit. Drop cloths laid down in the work path. We ask before moving furniture, toys, or anything that isn’t ours. If you have a dog who’s nervous around strangers, let us know and we’ll work with you to keep things calm.
- We explain the price, line by line. You should never sign a contract you don’t fully understand. We walk through every dollar with you before any work begins.
- Luis Serrano stands behind the work. Luis leads the team personally. If something isn’t right after the install, you have a direct line to the person accountable. That’s the 365-Day Done Right Promise in action.
Why San Antonio Winters Make Furnace Replacement Worth Planning
San Antonio doesn’t have brutal winters the way Chicago or Minneapolis does. But our winter temperatures are unpredictable, and heavy rainfall events in recent years have meant more moisture in crawl spaces and utility closets, which accelerates rust and corrosion in older furnaces. Homes built during the 1990s and early 2000s in neighborhoods like Cibolo Canyons, Encino Park, and Timberwood Park are now reaching the age where their original furnaces are failing.
When a furnace goes down in San Antonio, it’s not just discomfort. It can mean cancelled school days, disrupted work-from-home schedules, and a house that never quite warms back up. Planning a replacement before the next cold snap means your family isn’t caught off guard.
FAQs – Furnace Replacement
How much does furnace replacement cost in San Antonio?
Furnace replacement in San Antonio typically costs between $3,800 and $7,200, depending on the furnace’s efficiency rating, your home’s size, and whether ductwork changes are needed. Basic 80% efficiency units start around $3,800, while high-efficiency models with variable-speed blowers run up to $7,200 or more. Call (254) 271-2545 for a free in-home estimate with a written price.
How long does furnace replacement take?
Most furnace replacements in San Antonio are completed in a single day. Our crew arrives in the morning, removes the old unit, installs the new furnace, tests it thoroughly, and cleans up before they leave. Larger jobs that involve ductwork modifications or venting changes may take two days, and we’ll tell you upfront if that’s the case.
Is it better to repair or replace my furnace?
As a general rule, if your furnace is over 15 years old and the repair quote exceeds 50% of the cost of a new system, replacement is the better investment. Frequent repairs, rising energy bills, and uneven heating all point toward replacement. We’ll give you an honest assessment of both options with numbers attached, so you can choose what makes sense for your budget.
