Is the gap worth worrying about?
A 10% spread (roughly $1,100) is significant enough to plan around, but not fixed — off-peak timing and sharper bidding in Houston typically recover some of it.
Full HVAC system replacement by type: Allen vs Houston
Every full HVAC system replacement type gets its own localized price for each metro, using the same labor, climate and permit adjustments — a true apples-to-apples comparison.
| Type | Allen | Houston |
|---|---|---|
| AC + gas furnace (split system) | $6,450–$11,800 | $7,150–$13,050 |
| Heat pump system (air-source) | $7,800–$14,500 | $8,600–$16,050 |

Full HVAC system replacement by home size: Allen vs Houston
A full system (furnace + AC, or a heat pump + air handler) is sized to the whole home. Replacing both together costs more upfront but shares labor, permits, and a single install visit.
| Size | Allen | Houston |
|---|---|---|
| 1,000–1,500 sq ft | $6,450–$10,900 | $7,150–$12,100 |

| 2,500–3,000 sq ft | $10,000–$17,150 | $11,100–$19,000 |
| 3,000+ sq ft | $11,800–$19,850 | $13,050–$21,950 |

Cheapest time for full HVAC system replacement in either city
Why spring and fall are cheaper: contractors have open calendar space and compete harder for the work. Why summer and deep winter are expensive: a broken system in extreme weather isn't optional, so you lose your negotiating leverage.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
The costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.

Should I choose where to live based on full HVAC system replacement cost?
