Complete HVAC Installation · Richmond, TX
Most people land on this page because half their system just quit. The furnace won’t light on the first cold November morning, or the AC died in August and the unit is already fifteen years old. So the real question isn’t “can you fix it.” It’s “do I replace the broken half, or bite the bullet and do the whole thing now.” That’s what this page answers. We install the complete comfort system in Richmond homes, furnace, air conditioner, heat pump, ductwork, and thermostat, sized by Manual J and matched to AHRI spec, with all three system options laid out in plain numbers before you sign anything.

75 Degree AC installs complete HVAC systems in Richmond, TX, covering Fort Bend County, ZIPs 77406, 77407, and 77469, dispatched from our office at 20926 Bright Lake Bend Ct, Richmond TX 77407. You have three whole-system replacement paths: a gas furnace with a matched AC ($11,500 to $22,000 installed), an all-electric heat pump that replaces both ($12,000 to $22,000), or a dual-fuel hybrid ($14,000 to $22,000 and up). Every 2026 system uses R-454B or R-32 refrigerant, which runs 15 to 30 percent above 2024 R-410A pricing. CenterPoint Energy rebates here in Fort Bend cover $300 to $450 on a 16 to 17+ SEER2 AC, $500 to $750 on a 16 to 17+ SEER2 heat pump, and $75 on a qualifying smart thermostat. The federal Section 25C credit expired December 31, 2025. Every job starts with an ACCA Manual J load calculation for both heating (Fort Bend’s 28°F design temperature) and cooling, and you get the AHRI-matched system certificate at completion.

Call (346) 681-2625: Free In-Home Estimate Gas, heat pump, and dual-fuel quoted on every job.A complete HVAC system installation in Richmond TX runs $11,500 to $22,000 and up in 2026. Where you land depends on which of three systems you pick and how big the house is. Here is the breakdown installed:
| System type | Installed cost (Richmond) | Best for |
|---|---|---|
| Gas furnace + matched AC (96% AFUE / 16 SEER2) | $11,500 to $17,000 | Homes with existing natural gas; lowest upfront for full comfort |
| All-electric heat pump (17+ SEER2 / 9.5+ HSPF2) | $12,000 to $22,000 | All-electric homes; mild Fort Bend winters; CenterPoint $500 to $750 rebate |
| Dual-fuel hybrid (heat pump + gas furnace backup) | $14,000 to $22,000+ | Efficiency most of the year, plus hard-freeze insurance |
Your quote is a line-item document, not one big number. It splits out the outdoor unit (brand, model, SEER2), the indoor furnace or air handler (brand, model, AFUE or HSPF2), the evaporator coil, a new line set if one’s needed, the thermostat with its C-wire run, a new disconnect box, the condensate drain, the permit fee, and labor. After you sign, the only things that can move that price are conditions nobody could see before the install started. A corroded gas line. An attic structural problem. An electrical panel that can’t carry the load. Find one of those, and you get a written change order before we touch it.
Pricing shows up at the start, not the end. The single most common BBB complaint against Fort Bend HVAC companies is pricing: roughly 35 percent of disputes come from line items that showed up at the end of the job. Ours show up at the start. A new system is also a rebate opportunity, CenterPoint Energy pays between $300 and $750 depending on the equipment, and we file that paperwork at invoice so you’re not chasing it later.

Replace both at once when the second system is also near the end of its life or runs a different refrigerant than your new equipment. Otherwise, replacing just the broken one is usually the smarter spend. That is the honest answer, and it is the one most companies blur, because a full changeout is a bigger ticket.
Here is the math. Do both together and you pay for one mobilization, one permit, and one round of labor instead of two. That typically saves $1,200 to $2,500 versus splitting the jobs a year or two apart. You also get a true AHRI-matched pair, which protects your efficiency rating and your warranty. Bolt a new outdoor unit onto a mismatched old indoor coil and you void most manufacturers’ 10-year parts coverage. And since R-410A manufacturing ended January 1, 2025, a new 2026 condenser ships with R-454B or R-32. Your old indoor coil was built for R-410A, so pairing them is a compromise at best.
When does replacing one make sense? If the other system is under about eight years old, runs the current refrigerant, and passed its last inspection, keep it. We’ll tell you that to your face. We show you the failed part, put repair-versus-changeout numbers side by side in writing, and let you call it. Your money, your decision. Our job is to make the numbers clear.
The hardest part of a whole-system project in Richmond is picking between a gas furnace and AC, an all-electric heat pump, or a dual-fuel hybrid. So we quote all three, every time. For each one you see the equipment cost, the estimated annual heating and cooling cost at current CenterPoint rates, and the payback period. Then we apply the CenterPoint rebate to whichever options qualify.
| System option | What it is | Installed cost | Fort Bend fit | CenterPoint rebate |
|---|---|---|---|---|
| Gas Furnace and Air Conditioner Matched Installation | Separate gas furnace, AC condenser, and matched coil | $11,500 to $17,000 | Lowest upfront if you already have gas; strong heat in a freeze | $300 to $450 (AC tier) |
| Heat Pump Installation (all-electric) | One system heats and cools; no gas | $12,000 to $22,000 | Built for our 7-month cooling season and mild winters | $500 to $750 (heat pump tier) |
| Dual-Fuel Heat Pump System | Heat pump primary, gas furnace backup | $14,000 to $22,000+ | Efficiency most of the year, gas heat when it’s genuinely cold | $500 to $750 |
Fort Bend County is a textbook dual-fuel market. A heat pump is the most efficient way to heat through most of our winter, because it rarely gets cold enough to slow one down. The reason the gas backup earns its keep is February 2021. Winter Storm Uri. When the grid is buckling and it’s 12°F outside, a gas furnace keeps producing heat. A dual-fuel system runs the heat pump down to about 35°F, then hands off to gas below that, on its own, without you touching the thermostat.
Whichever you choose, every whole-system replacement we install is an AHRI-Matched Split System. The outdoor condensing unit, the indoor furnace or air handler, and the evaporator coil get selected and rated together as one tested system, and you get the AHRI 210/240 certificate number with your completion paperwork. That certificate is what makes your SEER2 and HSPF2 numbers real, and it is what qualifies you for the CenterPoint rebate. A job that calls itself “whole-system” but leaves your old indoor coil in place is not a matched system. We’ll put that in writing before we start, not after.
We don’t guess at tonnage. A company that sizes a system without asking about your insulation, your windows, or your attic is guessing, and an oversized system short-cycles, never pulls the humidity out, and wears itself out early in Fort Bend’s wet summers. Here is the order we work in.
We calculate the heating load (using Fort Bend’s 28°F winter design temperature) and the cooling load, factoring in square footage, ceiling height, insulation R-value, window orientation and area, air infiltration, and attic conditions. You see the output with the quote.
We run a static-pressure test on your existing ducts and check them against the new system’s airflow. Leaky or undersized ducts bleed off 20 to 30 percent of capacity, so this step decides whether ducts get sealed, modified, or replaced.
We match the furnace, condenser or heat pump, and coil into an AHRI-certified pair sized to the Manual J output.
We pull the mechanical permit (Fort Bend County Engineering for unincorporated 77406/77407, or the City of Richmond Building Department inside the city) and book the install.
Out with the old equipment, in with the new system, new line set and disconnect as needed, thermostat with a proper C-wire, condensate drain configured to code.
We verify the refrigerant charge and airflow, register your equipment for the full 10-year parts warranty, hand you the AHRI certificate, file your CenterPoint rebate, and book the final inspection.
Most single-system swaps wrap in a day. A full furnace-and-AC changeout usually runs one to two days. Add ductwork and you’re looking at two to four. Whatever it is, you get the timeline in writing before we start.
We install the major brands across heating and cooling, and we’ll name the exact models, because “we install all the top brands” tells you nothing. What you actually want to know is which furnace pairs with which condenser, and what efficiency it hits.
| Brand | Gas furnace | Heat pump | AC condenser | Top efficiency |
|---|---|---|---|---|
| Carrier | Infinity 59MN7 (98.5% AFUE) | Infinity 24VNA (20+ SEER2 / 10+ HSPF2) | Infinity 24ANB7 (20+ SEER2) | Greenspeed inverter, communicating |
| Trane | S9V2 (97% AFUE) | XV20i (20+ SEER2 / 10+ HSPF2) | XV20i AC (20+ SEER2) | Variable-speed, communicating |
| Lennox | Signature SLP99V (99% AFUE) | Signature SL25XPV (25 SEER2) | SL28XCV | Highest-efficiency tier |
| Goodman | GMVC96 (96% AFUE) | Matched on request | GSXC18 | Value tier, ComfortNet communicating |
| Daikin | DM96VC (96% AFUE) | Aurora DZ20VC (R-32, rated to −13°F) | DX20VC Fit | R-32 refrigerant, compact footprint |
A common entry spec for a Pecan Grove replacement is a Goodman GMSS80 (80% AFUE) paired with a SEER2 16 condenser. A Harvest Green or Aliana premium upgrade tends to be a Carrier Infinity 59MN7 or Lennox SLP99V modulating furnace matched to a variable-speed condenser. Every 2026 system carries R-454B (Carrier, Trane, Lennox) or R-32 (Daikin). Not phased-out R-410A inventory. If a competing quote looks suspiciously cheap, ask what refrigerant the equipment runs.
Three numbers show up on a whole-system quote, and most Richmond install pages explain none of them. Here is what each one measures.
That last point is the Fort Bend insight nobody else states out loud. In a climate that cools for seven months and heats for two, your dollars do more on SEER2 and HSPF2 than on furnace AFUE. We size the spend to the climate, not to the brochure.
Sometimes. And we test before we tell you. The Manual D static-pressure check is step two of every whole-system install, and the call goes one of three ways:
Putting a high-efficiency system on bad ducts is a sports car on flat tires. The Manual D check is what keeps the SEER2 rating you paid for once the system’s in the wall.
A whole-system replacement is a once-a-decade expense, so we make the money side workable two ways: plain-terms financing, and the CenterPoint rebate filed for you at invoice.
CenterPoint 2026 Standard Offer — $300 to $750 on a qualifying system plus $75 smart thermostat
Is there a federal tax credit for a new system in 2026? No. The federal Section 25C credit expired December 31, 2025. Texas has its own HEEHRA rebate program, but it’s funded and not yet launched, so we won’t promise it. For 2026, the CenterPoint rebate is the real, available money in Richmond, and we make sure you actually get it.
A whole-system install is the biggest comfort decision you make in a decade. Here is what stands behind ours.
We install complete HVAC systems across Richmond and the surrounding Fort Bend County communities, covering ZIPs 77406, 77407, and 77469.
| Communities | Install context |
|---|---|
| Harvest Green, Aliana, Candela | Newer master-planned communities where builder-grade systems put in between 2016 and 2020 are now hitting their first real upgrade or efficiency replacement. |
| Pecan Grove, Greatwood, Long Meadow Farms | Established neighborhoods where original 80% AFUE furnaces and aging condensers are reaching full-system replacement age. |
| Telfair, New Territory, Hillcrest, Bright Lake Bend | Mixed housing stock, full whole-system coverage. |
Because we dispatch from Bright Lake Bend Ct inside Fort Bend County, our crews reach an Aliana or Harvest Green driveway in minutes, not the hour a central-Houston installer faces. If your system is limping along while you plan the replacement, HVAC repair in Richmond can buy you time.
A Manual J load calculation is the ACCA-standard way to work out exactly how much heating and cooling a specific home needs, measured in BTUs, based on how it’s built and the local climate. Not a rule-of-thumb guess off the square footage. We run it on every Richmond install, using Fort Bend’s 28°F heating design temperature and roughly 98 to 99°F for cooling.
Skipping it is the most expensive shortcut in this trade. Oversize the system and it blasts cold air, satisfies the thermostat in a few minutes, and shuts off before it ever wrings the humidity out, so the house feels clammy at 74°F and the equipment short-cycles itself into an early grave. Undersize it and it never catches up in August. Right-sizing is the difference between a system that lasts fifteen years and one that struggles from day one.
Fort Bend County HVAC sizing reference (Manual J starting points):
| Home size | Typical cooling load | AC / heat-pump size | Furnace input | Recommended efficiency |
|---|---|---|---|---|
| 1,200 to 1,600 sq ft | 24,000 to 30,000 BTU | 2 to 2.5 ton | 60,000 to 80,000 BTU | 16 SEER2 / 96% AFUE / 8.8+ HSPF2 |
| 1,600 to 2,200 sq ft | 30,000 to 42,000 BTU | 2.5 to 3.5 ton | 80,000 to 100,000 BTU | 16+ SEER2 / 96% AFUE / 9+ HSPF2 |
| 2,200 to 3,000 sq ft | 42,000 to 54,000 BTU | 3.5 to 4.5 ton | 100,000 to 120,000 BTU | 17+ SEER2 / 96 to 98% AFUE / 9.5+ HSPF2 |
| 3,000+ sq ft | 54,000+ BTU | 5 ton (or zoned/staged) | 120,000+ BTU | Variable-speed, 18+ SEER2 |
These are starting ranges for Fort Bend’s climate. Your actual Manual J output shifts with insulation, windows, and orientation. We calculate yours before quoting.

A gas furnace plus matched AC runs $11,500 to $17,000, an all-electric heat pump $12,000 to $22,000, and a dual-fuel hybrid $14,000 to $22,000 and up. The exact figure depends on your home’s size, the efficiency tier, and whether the ductwork needs work. Every quote is line-itemed, and CenterPoint rebates of $300 to $750 apply to qualifying systems. Call (346) 681-2625 for a free in-home estimate.
Replace both together if the second system is also near the end of its life or runs older R-410A refrigerant. You save $1,200 to $2,500 in combined labor and permit costs, get a true AHRI-matched pair, and protect your warranty. If the other system is under about eight years old and healthy, replacing just the failed one is usually the smarter move. We put both options in writing and let you choose.
For most of Fort Bend’s mild winter, a heat pump heats more efficiently and cools all summer as a single system, and it qualifies for the larger CenterPoint rebate of $500 to $750. The tradeoff is hard-freeze events, where a gas furnace heats more reliably. That’s why a lot of Richmond homeowners land on a dual-fuel system: heat pump efficiency most of the year, with gas backup for the cold snaps.
A Manual J load calculation is the ACCA-standard way to size a system to your specific home’s heating and cooling needs in BTUs, using construction details and Fort Bend climate data instead of a square-footage guess. It prevents an oversized system that short-cycles and never dehumidifies, and an undersized one that can’t keep up in August. We run it, accounting for insulation, windows, and attic conditions, before we quote.
Not always. We run a Manual D static-pressure test first to find out. If your ducts are sized right and sealed, we reuse them. If there’s 15 percent or more leakage, we seal or modify. If they’re undersized or original to an older home, we replace. Bad ducts waste 20 to 30 percent of a new system’s capacity, so this check protects what you paid for.
Yes. CenterPoint’s 2026 Standard Offer Program pays $300 to $450 on a qualifying 16 to 17+ SEER2 air conditioner, $500 to $750 on a 16 to 17+ SEER2 heat pump, and $75 on a qualifying smart thermostat, up to about $825 combined. The equipment has to be an AHRI-matched, ENERGY STAR system. We file the rebate paperwork for you at invoice.
A single-system swap usually finishes in a day. A full furnace-and-AC changeout typically takes one to two days. If the ductwork needs replacing, plan on two to four days. You get the timeline in writing before the job starts, and we confirm the schedule when we book it.
No. The federal Section 25C tax credit expired December 31, 2025, and Texas’s HEEHRA rebate program is funded but hasn’t launched. For 2026 in Richmond, the active incentive is the CenterPoint Energy rebate, $300 to $750 on qualifying systems plus $75 for a smart thermostat, which we apply at invoice.
