These ranges cover a complete installed system replacement — outdoor condenser, indoor coil, labor, refrigerant, and startup. They do not include ductwork replacement, electrical panel upgrades, or permit fees if required by your municipality. Actual pricing depends on your home's specific load calculation, ductwork condition, and equipment selection.
| System Size | Home Size (approx.) | Base Tier (Comfort 16) | Mid Tier (Performance 17–18) | Premium Tier (Performance 20+) |
|---|---|---|---|---|
| 2-Ton | Up to ~1,000 sq ft | $6,500–$8,000 | $7,500–$9,000 | $9,000–$11,000 |
| 2.5-Ton | ~1,000–1,300 sq ft | $7,000–$8,500 | $8,000–$10,000 | $9,500–$12,000 |
| 3-Ton | ~1,300–1,800 sq ft | $7,500–$9,500 | $9,000–$11,500 | $11,000–$13,500 |
| 3.5-Ton | ~1,800–2,200 sq ft | $8,000–$10,000 | $9,500–$12,000 | $12,000–$14,000 |
| 4-Ton | ~2,200–2,800 sq ft | $9,000–$11,000 | $10,500–$13,000 | $13,000–$15,500 |
| 5-Ton | 2,800+ sq ft | $10,500–$12,500 | $12,000–$14,500 | $14,500–$17,000+ |
Important: Texas home size does not directly determine tonnage — load calculations account for insulation, windows, ceiling height, sun exposure, and duct condition. An oversized system in Spring TX humidity causes as many problems as an undersized one. Always get a proper load calculation before signing a replacement contract.
One of the most common homeowner mistakes is comparing replacement quotes without knowing what each one includes. A $7,500 quote and a $9,500 quote may be identical — or one may exclude $2,000 in components the other includes. Here's what to look for.
✔ Should always be included. The main outdoor unit. Check the model number — it tells you the brand, efficiency tier, and SEER2 rating.
✔ Should always be included. The indoor coil matched to the condenser via AHRI certification. Some quotes swap this for a mismatched coil to lower price.
✔ Check carefully. Some quotes include a new air handler; others assume you keep your existing one. Critical for AHRI-rated system performance.
✔ Should be included. New systems in 2026 use R-454B refrigerant. Confirm the quote includes a full charge — not a partial fill.
✔ Should be included. Covers removal of old equipment, installation, electrical connections, refrigerant charge, and startup testing.
✔ Confirm. Some quotes include a new smart thermostat; others assume you keep the existing one. Matters for system compatibility.
✖ Usually excluded. If your ducts need repair, sealing, or replacement, this is typically quoted separately and can add $800–$5,000+.
✖ Usually excluded. Older homes may need a panel upgrade to handle a new system. Typically $500–$2,500 additional if required.
✖ Sometimes excluded. Harris County and surrounding municipalities require permits for replacement installs. Confirm if included or add $100–$500.
The model number is everything. Every quote should include the exact outdoor condenser model number, indoor coil model number, and AHRI reference number. Without those three pieces of information, you cannot compare two quotes accurately. See our model number guide for exactly what to look for.
Six factors explain most of the price variation between replacement quotes. Understanding them helps you evaluate what you're actually buying.
The single biggest cost driver after equipment tier. Tonnage is determined by a load calculation — not just square footage. Spring TX homes need proper sizing because our humidity requires the system to dehumidify as well as cool. An oversized system short-cycles and leaves your home humid. Undersized systems run constantly and wear out fast.
Texas is in the South region — the minimum SEER2 for new installations is 15.2 SEER2 as of 2023 federal standards. Moving from a base 15.2 SEER2 system to a 17–18 SEER2 system typically adds $1,500–$2,500 to the upfront cost but reduces monthly energy bills — an important calculation for Spring homes that run AC 9–10 months per year.
Carrier Comfort Series is the reliable entry point. Carrier Performance Series adds variable-speed components, better humidity control, and quieter operation — typically $1,000–$2,500 more. Trane XR and XV series are comparable alternatives. The right tier depends on your budget, how long you plan to stay in the home, and whether humidity control is a priority.
New systems manufactured in 2026 use R-454B refrigerant instead of R-410A, which is being phased out under EPA guidelines. R-454B equipment costs slightly more than R-410A systems but is required for new installations. If you're replacing an older R-22 system, there is no compatibility path — a full system replacement is the only option.
Attic air handlers with tight access, two-story homes, homes without existing electrical disconnect boxes, or systems requiring new line set runs add to labor cost. A straightforward single-story replacement with easy outdoor unit access and a clean attic install costs less than a complex two-story with a cramped attic and outdated electrical.
If your existing ductwork has significant leaks, damage, or incorrect sizing for the new system, duct modifications may be required. Older homes built before 2000 sometimes need electrical panel upgrades to handle a modern high-efficiency system. Both of these are separate from the equipment quote and should be assessed during an in-home estimate.
The right system for your Spring TX home: North Houston's combination of extreme heat and high humidity means your replacement system needs to handle both cooling and dehumidification. A proper load calculation from a licensed contractor protects you from oversized systems that cool too fast but leave your home feeling clammy — a common complaint we diagnose in Spring neighborhoods.
This is the most important question a Spring TX homeowner can ask before approving any HVAC work. The answer depends on five specific factors — not just the age of the system.

Most Spring TX homeowners pay between $6,500 and $14,000 for a complete installed AC system replacement, depending on system size, equipment tier, SEER2 rating, and installation complexity. A 3-ton Carrier Comfort system typically lands in the $7,500–$9,500 range installed. A 3-ton Carrier Performance 18 SEER2 system typically lands in the $9,000–$11,500 range installed. Free estimates are available on qualifying replacements.
System size is determined by a load calculation — not just square footage. Texas homes need to account for insulation quality, window count and direction, ceiling height, duct condition, and sun exposure. As a rough guide: 2-ton for up to ~1,000 sq ft, 3-ton for ~1,300–1,800 sq ft, 4-ton for ~2,200–2,800 sq ft. Never approve a replacement without a proper load calculation from a licensed contractor.
Often yes — Spring TX homes run their AC 9–10 months per year. Upgrading from 15.2 SEER2 to 18 SEER2 typically adds $1,500–$2,500 upfront but can reduce monthly cooling costs by 15–25%. For homeowners planning to stay 5+ years, the payback period is often 3–5 years. For shorter-term stays, the base tier usually makes more financial sense.
Not typically. Most AC replacement quotes cover the outdoor condenser, indoor coil, refrigerant, labor, and startup. Ductwork modifications or replacement are usually quoted separately and can add $800–$5,000+ depending on the extent of work needed. Always confirm during your in-home estimate whether ductwork is included.
AHRI (Air-Conditioning, Heating, and Refrigeration Institute) certifies that specific combinations of outdoor condenser, indoor coil, and air handler perform as rated together. An AHRI-rated matched system ensures the SEER2 rating you're paying for is actually achieved. Mismatched systems perform below rated efficiency, void manufacturer warranties, and can fail prematurely. Always ask for the AHRI reference number before signing a replacement contract.
R-410A is being phased out under EPA regulations. New AC systems manufactured in 2026 use R-454B, a lower-global-warming-potential refrigerant. If you're replacing an older system, your new equipment will use R-454B. If your current system uses R-22, replacement is almost always the right financial decision since R-22 refrigerant now costs significantly more per pound than R-410A or R-454B.
Yes. AC Repair Expo Heating & Cooling Inc offers 0% financing on qualifying AC replacement systems, subject to approval and program terms. Financing is discussed upfront during the estimate — before you sign anything. See our financing page for details or call either location to ask about current programs.
Most residential AC replacements are completed in one day — typically 4–8 hours depending on system size, installation complexity, and whether ductwork modifications are needed. Two-story homes or systems requiring electrical work may take longer. We confirm the timeline during your in-home estimate so there are no surprises on installation day.
Yes, in most cases. Harris County and surrounding municipalities require permits for AC system replacements. AC Repair Expo Heating & Cooling Inc handles permit applications on qualifying jobs. Permit fees vary by municipality and are typically $100–$500. Always confirm whether permits are included or quoted separately.
AC repair cost covers fixing a specific failed component — a capacitor, motor, control board, or refrigerant leak.
