Answers to Common Questions
View All FAQsWhy Are HVAC Repairs So Expensive for Homeowners?
HVAC repairs can seem expensive because complex systems require licensed, background-checked experts and careful diagnostics. 24/7 emergency response and fully stocked trucks add readiness costs. Parts like compressors, motors, and refrigerant handling raise material costs. Upfront pricing shows the full job cost before work begins. You can trim costs with two tune-ups per year, member priority service, and by using our free second opinions or free service call with a paid repair.
Quick checks before calling:
- Set thermostat to cool and lower 5 degrees.
- Replace a clogged filter.
- Clear 2 ft around the outdoor unit.
- Check/reset the breaker.
