HVAC
HVAC covers your air conditioner, furnace or heat pump, thermostat, and duct system. Most calls start as a repair; the question is usually whether repairing an aging system is worth it versus replacing it.
Typical costs
Diagnostic visit
Often credited toward the repair.
$59 – $150
Capacitor / contactor
The most common AC failure.
$150 – $400
Refrigerant leak repair
Costlier on older R-22 systems.
$500 – $1,800
Full system replacement
Depends on tonnage and efficiency.
$6,500 – $14,000
Ranges reflect typical U.S. residential pricing. Local labor rates and access can move them.
Common questions
My AC stopped working — what should I check first?
Thermostat batteries, the breaker, and a clogged air filter cause a surprising share of no-cool calls. Also check for ice on the refrigerant line; if it's iced, turn the system off and let it thaw before a tech arrives.
When is replacement worth it?
A common rule: multiply the repair cost by the system's age. If it exceeds about $5,000, replacement usually wins. Systems over 15 years old with a major failure are rarely worth repairing.
Does a bigger unit cool better?
No. An oversized unit short-cycles, leaves humidity in the house, and wears out faster. Ask for a Manual J load calculation.
Things to watch out for
- A technician who recommends full replacement without showing you the failed component.
- Replacement quotes that skip a load calculation and just match your old system's tonnage.
- Refrigerant 'top-offs' repeated year after year — that means an unrepaired leak.
- High-pressure same-day discounts that expire when the truck leaves.
