St. Louis homeowner questions
How much does hvac cost in St. Louis?
St. Louis prices generally track the ranges shown above, adjusted for Missouri labor rates and permitting. St. Louis homes cycle through hail, humid summers, and icy winters — a freeze–thaw grind on roofs, pipes, and driveways. Comparing two or three local quotes is the most reliable way to find the fair St. Louis price.
Should I repair or replace my AC?
Multiply the repair quote by the system's age — over $5,000, replacement usually wins. Systems past 12–15 years with major failures are rarely worth fixing.
How long does AC replacement take?
Most straightforward swaps are done in one day. Duct modifications, electrical upgrades, or full system changes can extend to 2–3 days.
Why is my AC running but not cooling?
Usually a clogged filter, dirty coil, failed capacitor, or refrigerant leak. Check the filter first — then have a licensed tech test pressures and electricals.
