What We Check
Common AC repair symptoms.
Real Deal HVAC explains what is happening and gives you the practical next step.
Frozen Coil
Frozen coils can point to airflow restriction, dirty filters, coil issues, or refrigerant-related performance problems.
Short Cycling
Frequent starts and stops can come from controls, airflow, sizing, electrical parts, or protection limits.
Leaking / Drain Issues
Condensate drain and pan problems can cause water around the equipment.
Noises
Rattling, grinding, buzzing, or squealing can point to fan, motor, contactor, or mechanical issues.
Repair vs Replacement
Age, repeat breakdowns, repair cost, comfort, efficiency, and parts availability shape the recommendation.

FAQ
AC repair questions.
How much is an AC diagnostic?
AC diagnostic: $165 + HST.
Can you repair an AC that is blowing warm air?
Yes. Warm air can come from thermostat, airflow, coil, electrical, compressor, or refrigerant-performance issues.
Do you offer same-day AC diagnostics?
Same-day diagnostics are available where scheduling allows.
When should I replace instead of repair?
Replacement is worth discussing when the system is older, has repeat failures, needs a major repair, or no longer cools efficiently.
