- What's the typical cost to install a central AC system in Renton?
- Central AC installation in Renton typically ranges from $4,000 to $7,500, depending on ductwork condition and system capacity. Homes built in 1989 often have existing ductwork from furnace systems, which can reduce labor costs. Newer high-efficiency models cost more upfront but lower monthly utility bills. Get quotes from multiple local contractors to compare pricing and equipment warranties.
- Should I repair my existing air conditioner or replace it entirely?
- If your AC is over 10 years old and needs a compressor or condenser repair ($1,200–$3,000), replacement often makes financial sense. Renton homes with original 1989 systems should prioritize replacement for efficiency gains. Consider a full replacement ($4,000–$8,000) if repair costs exceed 50% of a new system's price. A licensed technician can assess your unit's condition and recommend the most cost-effective option.
- Why do ductless AC systems cost less than central air in Renton?
- Ductless mini-split systems ($2,000–$5,000 installed) avoid expensive ductwork installation or modification, making them cheaper than central systems in older Renton homes. They're ideal for additions or homes without existing ducts. However, central air cools entire homes more uniformly and integrates with existing furnace infrastructure. Choose based on your home's layout, budget, and cooling zone preferences.
