Call (346) 681-2625: Free In-Home Estimate Manual J sizing included on every quote.A new central AC system in Richmond runs $5,400–$14,800 installed, depending on size, efficiency, and whether ductwork needs work. The biggest swing factors are the tonnage your home actually requires (set by the Manual J load calculation, not the old unit’s label) and the SEER2 efficiency tier you choose. Here is the honest 2026 range by tier.
Most Richmond installs land in one of three tiers. The table below shows what you get and what it costs before any rebate.
| Tier | What you get | SEER2 | Installed cost (Richmond, 2026) |
|---|---|---|---|
| Basic | Single-stage split system, builder-grade replacement | 14.3 | $5,400 – $8,500 |
| Mid-range | Two-stage, better dehumidification | 15–16 | $8,500 – $11,500 |
| Premium | Variable-speed, communicating, max efficiency | 17–20+ | $11,500 – $18,500 |
These are 2026 Fort Bend ranges; the tier you land in is driven mostly by the system size your home calls for and how hard you want the unit working in a 100-plus-degree July.
Factors that move your price:
The CenterPoint rebate (and the credit that died): Richmond sits in CenterPoint Energy territory. Qualifying ENERGY STAR systems earn a $300–$750 rebate, up to $500 on a qualifying heat pump and $75 on a smart thermostat. We file it on your invoice, so you do not chase paperwork after the install. One thing to clear up while you are comparing quotes: the federal Section 25C tax credit expired December 31, 2025. So if a contractor is still dangling a $2,000 federal credit at you in 2026, they are working from old information. The CenterPoint rebate is the incentive that is actually live.

If your system is past 12 years old and you have paid for two repairs in the last two summers, replacement usually beats another repair bill. Below are the seven signals we see most often on Richmond estimate calls, in rough order of how strongly they point to replacement rather than repair.
Most Fort Bend systems start their decline here, and parts get harder to source.
Even though your thermostat habits have not changed, a failing compressor or coil pulls more power to do less cooling.
The “$5,000 rule” applies: multiply the unit’s age by the repair quote, and if it clears $5,000, replacement is the smarter spend.
Often a sizing or duct problem the original installer never addressed.
R-22 is gone, and R-410A is being phased out, so refrigerant top-offs get expensive fast.
Smells that persist after a service visit point to a failing blower motor or compromised coil.
Harvest Green, Aliana, and Candela almost always shipped with the 14.3 SEER2 single-stage minimum. They run fine for a few years, then start failing right as the builder warranty lapses. If your home fits that profile and the bills are rising, you are in the replacement window.
If your unit just quit and the house is heating up, we also handle emergency AC repair while you decide whether to repair or replace.

A quick note from the field. Leaky attic ductwork can throw away 20 to 30 percent of the efficiency you just paid for, and Fort Bend attics are full of it. So we check static pressure and inspect the ducts before we quote a system. Sometimes the duct fix matters more than the SEER2 number on the box. Owners never expect to hear that, but it is true more often than you would think.
We install matched systems from Carrier, Trane, Lennox, Goodman, and Daikin, plus American Standard, Rheem, and Bryant, ranging from value single-stage units to variable-speed communicating systems. The table below pairs each brand’s premium and value model so you can see SEER2 range, compressor type, and warranty side by side.
| Brand | Premium model | Value model | SEER2 range | Compressor | Warranty (registered) |
|---|---|---|---|---|---|
| Carrier | Infinity 24ANB7 | Performance 17 | 16–20+ | Variable / dual | 10-yr parts |
| Trane | XV20i | XR16 | 16–21.5 | Variable TruComfort | 10-yr parts |
| Lennox | SL28XCV | EL16XC1 | 16–28 | Variable / single | 10-yr parts |
| Goodman | GSXC18 | GLXS5BA | 14.3–19 | Single / dual | 10-yr parts |
| Daikin | DX20VC Fit | DX16TC | 16–23.5 | Variable inverter | 12-yr parts |
We also install the American Standard Platinum 20, the Rheem Prestige RA20, and the Bryant Evolution when those fit the home or match an existing system. Every install is verified in the AHRI Directory — the matched-pair rating that keeps your SEER2, warranty, and CenterPoint rebate valid.
Two things matter more than the badge on the unit. First, the matched system. We install AHRI-certified matched pairs so your rated SEER2, your manufacturer warranty, and your CenterPoint rebate all hold together. Let someone swap in a cheaper off-brand coil to shave the quote and you have voided the efficiency rating, the warranty, and the rebate in one move. Not worth it. Second, the refrigerant. Every system we install runs R-454B (Puron Advance) or R-32, never phased-out R-410A. Manufacturing of R-410A ended January 1, 2025 under the EPA AIM Act. So if a system quoted to you in 2026 is still R-410A, ask why. A leftover unit on the old refrigerant costs more to service every year as that product gets scarce, sometimes $50 to $80 a pound.

SEER2 is the efficiency rating the DOE adopted in 2023, and Texas sits in the South region where new split systems must meet a 14.3 SEER2 minimum (13.8 for units 3.75 ton and larger). It replaced the older SEER number using a tougher test that better reflects real duct conditions, so 14.3 SEER2 is roughly the old 15 SEER. We recommend 16-plus SEER2 for Fort Bend County’s 7-month cooling season.
Why 16-plus pays back faster here. A higher-efficiency unit earns its premium through runtime. With 100-plus days above 90 degrees and roughly seven months of cooling, a Richmond system runs far more hours than one in a cooler climate, so each efficiency point returns more on your bill. The same SEER2 jump that takes a decade to pay off up north pays back faster in Fort Bend.
Why variable-speed beats single-stage for Richmond humidity. Summer humidity here sits at 75 to 85 percent. A variable-speed compressor runs longer at low capacity instead of blasting cold and snapping off, and those long, gentle cycles wring far more moisture out of the air. It is the difference between a house that reads 74 degrees and still feels swampy and one that feels genuinely dry at the same setting. Every system we install runs R-454B or R-32, the current low-GWP refrigerants, never recycled R-410A inventory.
A Manual J load calculation is the ACCA-standard heat-gain math that determines the exact size of AC your home needs, using square footage, insulation, window area and orientation, ceiling height, and occupancy. It is the difference between a system sized by engineering and one sized by a guess off the old unit's label.
Here is why rule-of-thumb sizing fails in Fort Bend. An oversized system blasts cold, satisfies the thermostat fast, and shuts off before it ever runs long enough to pull the humidity out. Your house sits at 74 degrees and still feels swampy. The short-cycling also wears the compressor out early. Go the other way and an undersized system runs nonstop through July, never catches up, and burns out in three or four summers. Same root cause, opposite symptom. Both are common when a contractor skips the load calc to save an hour on the estimate.
Every quote we give starts with a Manual J. If a competitor's quote does not mention one, ask them how they sized your system. The honest answer is usually that they eyeballed it.
Yes, you can finance a new AC system, and we offer 0% APR options with approval in minutes. A $5,000 to $15,000 purchase rarely lands at a convenient time, so we work with two lenders and stack the CenterPoint rebate on top.

Is there a federal tax credit for AC in 2026? No. The Section 25C credit expired December 31, 2025. The Texas HEEHRA rebate program is funded but has not launched yet, so we do not promise it. The CenterPoint rebate is the real, available incentive in Richmond today, and we would rather tell you that straight than quote you a credit that no longer exists.
75 Degree AC holds Texas license TACLA72152E and runs a Richmond office at 20926 Bright Lake Bend Ct, inside Fort Bend County. That means a licensed crew shows up to your home, not a day-labor sub with a magnetic door sign. We have worked the Houston metro since 2016. Here is what sets the install apart.
We install AC across Richmond’s master-planned and established communities, from new builds in Harvest Green to 1990s stock in Greatwood, and we know the system age each one tends to run. The table below maps the neighborhoods we cover most, with ZIP and the typical install context our crews see.
| Neighborhood | ZIP | Install context |
|---|---|---|
| Harvest Green | 77407 | New builds; builder-grade 14.3 systems in 5–7-yr replacement window |
| Aliana | 77407 | Master-planned; new-construction plus early replacements |
| Long Meadow Farms | 77406 | Newer builds; 3–5 ton systems typical |
| Candela | 77406 | Builder-grade systems in first replacement cycle |
| Pecan Grove | 77469 | Established; older stock, higher replacement rate |
| Greatwood | 77469 | 1990s–2000s builds; aging systems |
| New Territory | 77479 | 1990s–2000s; 15–25-yr systems |
| Telfair | 77479 | Upscale builds; higher-SEER2 installs |
We also cross the border for installs in Sugar Land (77479), Rosenberg (77471), and Missouri City (77459).
The takeaway from that map: the newer the neighborhood, the more we see builder-grade systems failing early; the older the stock, the more we see 15-to-25-year units finally giving out. If your unit is limping along right now, AC repair in Richmond can buy you time while you plan the replacement.
We install AC in Richmond, Texas, in Fort Bend County, covering ZIP codes 77406, 77407, and 77469. Not Richmond, Virginia.

“Kenny Ho and his team were very communicative, professional, and helpful during the entire process. I had to replace an entire HVAC system and he recommended me the best unit efficiency and even worked with me to figure out different models to find the one that worked best for my situation.”
“Great service from Kenny and his team. The installation of my new AC went smoothly and seamlessly, and I really appreciate the work they performed.”
“I'm very happy with the service and the staff. Highly recommended.”
A new central AC system in Richmond runs about $5,400 to $14,800 installed, depending on size, SEER2 efficiency tier, and whether your ductwork needs work. Basic single-stage systems start around $5,400, mid-range two-stage units land near $8,500 to $11,500, and premium variable-speed systems run higher. A CenterPoint rebate of $300 to $750 can come off a qualifying system.
Most standard system replacements are completed in one day. A straightforward condenser, coil, and air handler swap usually takes a single crew a full working day. If we are also replacing or reworking ductwork, or installing in a difficult attic, the job can run one to two days. We confirm the timeline at your free estimate.
The right size is set by a Manual J load calculation, not square footage alone. A typical 2,000 sq ft Richmond home often lands around 3 to 3.5 ton, but insulation, window count, orientation, and ceiling height all change the number. We run the load calc on every estimate so the system matches the house instead of a guess.
Yes. CenterPoint Energy offers a $300 to $750 rebate on qualifying ENERGY STAR systems (up to $500 on a qualifying heat pump and $75 on a smart thermostat), and we file it on your invoice. The federal Section 25C tax credit expired December 31, 2025, and the Texas HEEHRA program has not launched yet, so CenterPoint is the live incentive.
The minimum is 14.3 SEER2 for systems under 3.75 ton in the DOE South region, which includes Houston and Fort Bend County. We recommend 16-plus SEER2 here because the 7-month cooling season means a higher-efficiency unit pays back faster than it would in a cooler climate. Variable-speed units in the 17-to-20-plus range also dehumidify better.
Use the “$5,000 rule”: multiply the system’s age by the repair quote, and if the result clears $5,000, replacement usually wins. A 13-year-old system facing a $600 repair clears it. Systems still running R-22 or aging R-410A are also strong replacement candidates, because refrigerant costs keep rising as those products phase out.
Yes. A mechanical permit is required for HVAC installation in Fort Bend County, followed by a TDLR final inspection. We pull the permit through Fort Bend County Engineering for unincorporated 77406 and 77407 addresses, or the City of Richmond Building Department for 77469, and schedule the inspection. A permitted install protects you at resale and appraisal.
For most Richmond homes, yes. A variable-speed compressor runs longer at low capacity instead of cycling on and off, which pulls more moisture out of the air during our 75-to-85-percent humidity summers. Over a 7-month cooling season, that means a more comfortable house at a higher thermostat setting and lower run-cost. The comfort difference in humid weather is the main reason owners choose it.
Yes. We offer financing through Synchrony, including 0% APR promotional options with approval in minutes, and through GreenSky, which adds 12-month same-as-cash and longer-term plans. You can stack the CenterPoint rebate on top of either. We walk through the plain terms at your estimate so there are no buried rate jumps.
