Furnace Replacement Cost in Richmond TX at a Glance
Here is a quick look at what homeowners in Fort Bend County typically pay for a full furnace replacement in 2027, including installation:
| Furnace Type | Unit Cost | Installed Cost |
|---|---|---|
| Gas Furnace (80% AFUE) | $800 to $1,800 | $2,500 to $5,000 |
| Gas Furnace (96% AFUE) | $1,500 to $3,500 | $4,000 to $8,500 |
| Electric Furnace | $600 to $1,800 | $1,800 to $5,000 |
| Heat Pump (Air Source) | $2,000 to $5,000 | $4,000 to $12,000 |
Installation labor in the Houston metro area, including Richmond and Sugar Land, typically runs between $800 and $2,000 on its own. That cost depends on how complex the job is, whether your existing ductwork needs changes, and how long the install takes.
How Furnace Type Affects Your Cost
Gas Furnaces
Gas furnaces are the most common choice in Richmond TX, and for good reason. Natural gas is widely available in Fort Bend County, and a gas furnace heats a home faster and more evenly than most electric alternatives.
A standard 80% AFUE gas furnace costs between $2,500 and $5,000 installed. A high-efficiency model at 96% AFUE runs from $4,000 to $8,500 but saves you more on heating bills over time.
For most Richmond TX homes, a mid-range gas furnace at 80% or 90% AFUE hits the sweet spot between upfront cost and long-term savings. Because winters here are mild compared to states farther north, the payback period on a 96% model is longer. That said, if you plan to stay in your home for 10 or more years, the high-efficiency option often makes sense.
Electric Furnaces
Electric furnaces cost less to buy and install, typically falling between $1,800 and $5,000 installed. They have fewer moving parts, which means lower maintenance costs. However, because electricity costs more per BTU than natural gas in most Texas ZIP codes, your monthly heating bills will run higher with an electric furnace.
If your home does not have a natural gas line, electric is the practical choice. Installing new gas service adds $500 to $2,000 on its own, which can close the gap quickly.
Heat Pumps
Heat pumps are worth mentioning here because they can replace a furnace entirely. A heat pump handles both heating and cooling from one unit. In Richmond TX, where winters are short and summers are long, a heat pump often makes a lot of financial sense.
Installed costs run from $4,000 to $12,000 depending on the system size. The federal tax credit for qualifying heat pumps can bring that number down significantly in 2027. Ask us about current rebate eligibility when you call.
Cost by Efficiency Rating (AFUE)
AFUE stands for Annual Fuel Utilization Efficiency. It tells you what percentage of the fuel your furnace burns actually becomes heat inside your home. The rest goes out the exhaust flue.
| AFUE Rating | What It Means | Installed Cost Range |
|---|---|---|
| 80% AFUE | Minimum allowed by federal code | $2,500 to $5,000 |
| 90% to 92% AFUE | Mid-range efficiency | $3,000 to $6,500 |
| 96% to 98% AFUE | High efficiency | $4,000 to $8,500 |
For Richmond TX homeowners, 80% AFUE is almost always sufficient. Because we use the furnace for maybe three to four months out of the year, the fuel savings from a 96% model versus an 80% model are real but modest. Over 10 years, the difference in gas bills typically ranges from $400 to $900 total for a Texas-sized home, depending on your square footage and usage habits.
That said, if your home is larger than 2,500 square feet or you tend to run the heat more often than average, bumping up to 90% AFUE is usually worth the difference in price.
Cost by Furnace Size (BTU Output)
Furnaces are sized by BTU output. Getting the right size matters more than most homeowners realize. Too small and the furnace runs constantly without fully heating the house. Too large and it short-cycles, which wears it out faster and creates uneven temperatures from room to room.
| Home Size | Recommended BTU Output | Installed Cost Range |
|---|---|---|
| Under 1,000 sq ft | 40,000 to 60,000 BTU | $2,000 to $4,500 |
| 1,000 to 1,500 sq ft | 60,000 to 80,000 BTU | $2,500 to $5,500 |
| 1,500 to 2,500 sq ft | 80,000 to 100,000 BTU | $3,000 to $7,000 |
| Over 2,500 sq ft | 100,000 to 120,000 BTU | $3,500 to $8,500 |
These are general estimates. The right size for your specific home depends on insulation quality, ceiling height, window area, and how many levels the home has. Temper Mechanical does a proper Manual J load calculation before recommending any unit size. That is the only accurate way to size a furnace, and any contractor who quotes you a price without one is guessing.
Cost by Brand
Brand reputation matters for furnace replacements. A lesser-known brand might cost less upfront, but warranty coverage and parts availability can vary widely.
| Brand | Reputation | Installed Cost Range |
|---|---|---|
| Carrier | Premium | $4,000 to $8,500 |
| Trane | Premium | $4,500 to $9,000 |
| Lennox | Premium | $4,000 to $8,500 |
| Bryant | Mid-range | $3,000 to $7,000 |
| Rheem | Mid-range | $2,800 to $6,500 |
| Goodman | Budget-friendly | $2,500 to $5,500 |
Goodman has a strong reputation for value. The company is owned by Daikin, one of the largest HVAC manufacturers in the world, so parts are widely available. For most Fort Bend County homeowners who want solid performance without the premium price tag, Goodman or Rheem are worth a serious look.
Carrier and Trane earn their premium reputation with longer warranties and a deep network of service technicians. If you want top-level reliability and long-term support, either brand is a solid choice.
What Is Included in the Installation Cost?
When you get a quote from a licensed HVAC contractor in Richmond TX, the installation price should cover the following:
Removal and Disposal of Your Old Furnace
Your old unit has to come out before the new one goes in. This includes disconnecting the gas line, electrical wiring, and flue connections safely.
New Furnace Unit
The cost of the unit itself at the size and efficiency rating you selected.
Gas Line Connection
The contractor connects the new unit to your existing gas supply. If modifications are needed due to a different unit size or location, that adds to the cost.
Electrical Wiring
Furnaces require dedicated electrical connections for the blower motor and ignition system.
Flue and Venting
The exhaust flue must match the requirements of the new unit. High-efficiency furnaces use different venting than standard models, which can require running new PVC pipe through an exterior wall.
Thermostat Calibration and System Testing
A complete installation includes programming the thermostat, running the system through a full heating cycle, and verifying that airflow is correct throughout your home.
Permits
Mechanical permits are required for HVAC work in Fort Bend County. A licensed contractor handles the permit filing. Unpermitted work can cause problems when you sell your home.
Hidden Costs That Can Add to Your Total
Most homeowners budget for the furnace and installation, then get surprised when additional items come up during the job. Here is what to budget for in advance:
Ductwork Repairs or Modifications
If your existing ductwork is damaged, too small, or configured for a different unit layout, it will need to be modified. Duct repairs range from $300 to $1,500 depending on the scope.
Thermostat Upgrade
Older thermostats are not compatible with new high-efficiency furnaces. A smart thermostat like a Nest or Ecobee adds $150 to $350 to the job but also helps you save on energy costs year-round.
Carbon Monoxide Detector
Required in Fort Bend County for any gas appliance installation. If you do not already have one in good working order, add $30 to $80.
Emergency or After-Hours Service
If your furnace fails during a cold snap and you need same-day service, after-hours charges apply at some companies. Temper Mechanical offers same-day service throughout the Richmond TX area. Call us at +1 (346) 485-8142 to confirm availability.
When Should You Replace Instead of Repair?
Knowing whether to repair or replace is one of the most common questions we get. There is no single right answer for every situation, but a few factors make replacement the smarter financial move:
Age of the Furnace
Gas furnaces have an average lifespan of 15 to 20 years. If your unit is 15 years or older and needs a significant repair, replacement is often more cost-effective. You are essentially paying to extend the life of a system that is already near the end of its useful service.
The 50% Rule
If the repair cost is more than 50% of the price of a new system, replace it. A $1,500 repair on a furnace that would cost $3,000 to replace does not make financial sense, especially when the new unit comes with a warranty and will run more efficiently from day one.
Frequent Breakdowns
If you have called for repairs more than twice in the past two years, that pattern usually continues. At a certain point, the cumulative repair cost adds up to more than what a new unit would have cost.
Rising Energy Bills
If your heating costs have climbed noticeably without a change in how you use the system, the furnace is likely losing efficiency. A new 96% AFUE unit versus an old one running at 65% efficiency can cut your monthly heating bill noticeably.
Uneven Heating
If certain rooms are cold while others are too warm, it could be a ductwork issue, but it can also indicate a furnace that is no longer distributing air properly. A proper diagnostic will tell you which.

How to Get the Best Price on a Furnace in Richmond TX
Get Multiple Quotes
Get at least two or three quotes from licensed HVAC contractors in Fort Bend County. Prices can vary by $1,000 or more on the same equipment, mostly based on overhead and markup on parts.
Ask About Manufacturer Rebates
Carrier, Trane, Lennox, and other major brands run seasonal rebate programs. A $200 to $500 rebate on qualifying equipment is not unusual. Your contractor should know what is currently available.
Check for Federal Tax Credits
In 2027, qualifying high-efficiency furnaces and heat pumps are still eligible for federal energy efficiency credits. Check with a tax professional for the specifics on your situation.
Time It Strategically
The best time to replace a furnace is in the fall, before demand peaks during cold snaps. Late October and November, before temperatures drop consistently, is when contractors have more availability and scheduling flexibility.
Ask About Financing
Many HVAC contractors offer financing through third-party lenders. Spreading a $5,000 installation over 24 months at a reasonable rate makes a quality unit accessible without draining your savings.

Frequently Asked Questions
How long does furnace replacement take?
A standard furnace replacement in Richmond TX takes four to six hours for a straightforward swap-out. If ductwork modifications are needed or the install is in a tight location, it can run a full day. Temper Mechanical schedules most residential replacements as single-day jobs.
Do I need a permit to replace a furnace in Fort Bend County?
Yes. A mechanical permit is required for furnace replacement in Fort Bend County. Any licensed HVAC contractor will handle the permit application as part of the job. If a contractor offers to skip the permit to save time or money, that is a red flag.
What size furnace do I need for a 2,000 square foot home in Richmond TX?
For a 2,000 square foot home in the Richmond TX climate zone, an 80,000 to 100,000 BTU furnace is the typical range. The exact size depends on your insulation, window area, ceiling height, and layout. Temper Mechanical does a proper Manual J load calculation to get this right rather than guessing from square footage alone.
How much does it cost to replace just the heat exchanger?
A heat exchanger replacement costs between $1,000 and $2,000 in parts and labor. Because the heat exchanger is the core component of a gas furnace, and because a cracked heat exchanger creates a carbon monoxide risk, many HVAC professionals recommend full replacement rather than repairing a heat exchanger on a furnace that is more than 10 years old.
Can I replace my furnace myself?
No. Furnace replacement involves gas line work, electrical connections, and flue venting. All of these require a licensed contractor in Texas. DIY gas work is illegal and creates serious safety risks including gas leaks and carbon monoxide poisoning.
What is the best furnace brand for Richmond TX?
There is no single best brand for every situation. Goodman and Rheem offer strong value at mid-range prices. Carrier and Trane are premium brands with longer warranties and excellent parts availability. The right furnace for your home depends on your budget, how long you plan to stay in the house, and what your existing setup is compatible with.
Will a new furnace lower my energy bills?
Yes, in most cases. If your current furnace is 15 or more years old, it is probably running at 60% to 75% AFUE. A new 80% AFUE furnace is meaningfully more efficient, and a 96% AFUE model even more so. In Richmond TX, where winters are shorter than in northern states, the monthly savings will be smaller than in colder climates, but you will still notice the difference on your bill from November through February each year.
How often should a furnace be serviced after installation?
Once per year, ideally in the fall before the heating season begins. An annual tune-up keeps the unit running efficiently, catches small problems before they become expensive ones, and extends the overall lifespan of the system. Call us at +1 (346) 485-8142 to schedule a fall tune-up before the season gets busy.
