HVAC costs range from a quick $150 diagnostic visit to $10,000+ for a full system replacement. Repair calls average $150–$500 in the US, while a new central AC or furnace installation runs $3,000–$7,000. Heat pump installations — increasingly popular across all four markets, with Spain seeing the biggest wave under Next Generation EU funding — cost $4,000–$12,000 depending on the system and complexity. Hourly rates: $75–$150 (US), PLN 100–300 (Poland), €60–€110 (Netherlands), and around 35 to 65 euros per hour in Spain.

What affects the cost?
- System type — heat pumps cost more upfront than conventional AC but save on energy bills
- System size (tonnage) — larger homes need larger systems
- Refrigerant type — R-410A is standard; older R-22 (being phased out) is expensive
- Ductwork condition — if existing ducts are damaged or undersized, expect additional costs
- Season — peak summer AC demand and winter heating emergencies drive prices up
- Energy efficiency rating — higher SEER/HSPF units cost more but save on energy
Costs by country
HVAC costs in the United States
US HVAC technicians charge $75–$150 per hour for repair work, with a service call fee of $75–$200. Major installations are quoted flat-rate based on system sizing. The Inflation Reduction Act offers up to $8,000 in heat pump tax credits and rebates, significantly reducing the out-of-pocket cost. High-efficiency systems may also qualify for utility company rebates.
HVAC costs in Spain
Spanish HVAC technicians charge €35–€65 per hour in Spain for repair work, with desplazamiento (callout) of €40–€70. Mediterranean-coast demand is structural — Alicante, Valencia, Málaga, and Barcelona installers stay booked 4-6 weeks ahead from May through September. A split AC unit (1×1) costs €1,200–€2,500 installed; a multi-split (1×3) runs €3,000–€5,500. Heat-pump aerotermia systems cost €6,000–€12,000+, with up to 40% recoverable through Next Generation EU and IDAE rebates (RD 477/2021).
Spain regulates HVAC under the RITE (Reglamento de Instalaciones Térmicas en Edificios, RD 178/2021). Anyone installing or maintaining heating/cooling needs the Carné de Instalador Térmico (RITE-IT) or Mantenedor Térmico (RITE-MT). On top of that, any refrigerant work — recharging an AC, retrofitting a heat pump — requires an F-Gas certificate (RD 115/2017). Always confirm both certifications on the quote: the cheap "we'll just top up the gas" offers usually come from unregistered technicians whose work voids manufacturer warranty and home insurance.
How to save on HVAC costs
- Regular maintenance — annual tune-ups catch small problems before they become expensive failures
- Change filters regularly — a dirty filter makes your system work harder and fail sooner
- Schedule off-peak — install new systems in spring or fall when demand is lower
- Claim available rebates — IRA credits, Czyste Powietrze, ISDE subsidies
- Get multiple quotes — prices vary significantly between contractors
Frequently asked questions
How much does HVAC repair cost on average?
Most US HVAC repairs run $150–$650, with the national average around $350. Service call fees are $75–$150. Major repairs (compressor replacement, blower motor) can hit $1,200–$2,500. Annual maintenance contracts ($150–$400/year) typically include 10–15% off repairs.
When should I repair vs replace HVAC?
The 5,000 rule: multiply your system's age by the repair cost. If it's over $5,000 and the unit is 10+ years old, replace. Also replace if repair costs more than 50% of a new system, or if you're paying for repairs every year.
How long do HVAC systems last?
Central AC: 12–17 years. Furnaces: 15–20 years. Heat pumps: 10–15 years (run year-round). Boilers: 15–25 years. Annual maintenance and changing filters every 1–3 months can extend lifespan by 3–5 years.
Why is my HVAC repair so expensive?
Three main drivers: refrigerant (R-410A is $50–$100 per pound, R-22 is $150+), proprietary parts that only the manufacturer makes, and labor — modern systems require certification to service. After-hours emergency calls add 50–100%.
