Heating and AC Repair FAQs

How do I know if I need heating or AC repair?

Common signs include inconsistent temperatures between rooms, unusual banging or squealing noises, frequent cycling (turning on and off rapidly), or a sudden, unexplained spike in your monthly energy bills.

When should I replace my HVAC system instead of repairing it?

If your system is over 10–12 years old and requires a repair that costs more than 50% of its total value, replacement is usually the smarter investment. Newer systems offer significantly higher SEER2 ratings, which can lower your utility bills by up to 30%.

Why is my AC running but not cooling the house?

This is often caused by a dirty air filter, a blocked outdoor condenser unit, or a refrigerant leak. Our technicians use specialized diagnostic tools to find the root cause without the guesswork.

How often should I schedule HVAC maintenance?

To maintain your manufacturer's warranty and prevent 90% of common breakdowns, you should schedule a "Precision Tune-Up" twice a year—once in the spring for your AC and once in the fall for your heater.

Do you offer emergency HVAC services in Langley?

Yes! We know that HVAC systems don't wait for business hours to fail. We have emergency technicians on standby 24 hours a day, 7 days a week, to restore your comfort immediately.
