What Size HVAC System Do I Need?
Choosing the correct HVAC size is critical for comfort and efficiency.
A system that is too large may cool the home quickly but leave excess humidity in the air.
A system that is too small may run constantly and struggle to keep up during summer heat.
As a general guideline:
| Home Size | Typical HVAC Size |
| 1,200 β 1,500 sq ft | 2 β 2.5 tons |
| 1,500 β 2,000 sq ft | 2.5 β 3 tons |
| 2,000 β 2,500 sq ft | 3 β 4 tons |
| 2,500 β 3,200 sq ft | 4 β 5 tons |
Professional contractors use a Manual J load calculation to determine the correct system size.

Should You Repair or Replace Your HVAC System?
Many homeowners wonder whether they should repair their existing HVAC system or replace it entirely.
A helpful rule many HVAC professionals use is the 5,000 rule:
Multiply the age of the system by the repair cost.
If the number exceeds 5,000, replacement may be the better investment.
Example:
| System Age | Repair Cost | Recommendation |
| 6 years | $500 | Repair |
| 12 years | $700 | Consider replacement |
| 15 years | $600 | Replace |
