The answer to 'cost of replacement' is that the cost of replacing an HVAC system can vary widely depending on several factors. Generally, the cost can range from a few thousand dollars for a basic system to tens of thousands for a high-end, complex installation. The key factors that influence the cost include the size and efficiency of the new system, the complexity of the installation, the brand and model, and any necessary ductwork or electrical upgrades.
It's essential to get quotes from local HVAC professionals to get an accurate estimate for your specific home and needs. They can assess the current system, recommend the right replacement, and provide a detailed cost breakdown. Remember that while a higher upfront cost may seem daunting, investing in an energy-efficient system can save you money in the long run through lower utility bills and reduced maintenance costs.
