Is the price difference a dealbreaker?

Central AC installation by home size: Allen vs Austin
Central AC is sized in tons of cooling — about one ton per 500–600 sq ft. Undersizing leaves you hot; oversizing short-cycles and wastes money, so a Manual J load calculation matters.
| Size | Allen | Austin |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,400–$7,700 | $5,050–$8,800 |
| 1,500 sq ft (≈2.5 tons) | $4,900–$9,100 | $5,600–$10,400 |
| 2,000 sq ft (≈3 tons) | $5,350–$10,500 | $6,100–$12,000 |
| 2,500 sq ft (≈4 tons) | $6,750–$12,350 | $7,750–$14,150 |
| 3,000+ sq ft (≈5 tons) | $8,150–$15,200 | $9,350–$17,350 |

What hvac pros earn in each metro

Cheapest time for central AC installation in either city
Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
How much should you really budget for HVAC in 2026?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
The longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
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 efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
