Q&A Section
1. What causes refrigerant leaks?
Refrigerant leaks can occur due to wear and tear on the HVAC system, corrosion, or damage to the coils during maintenance.
2. How can I tell if my thermostat is faulty?
If your AC is not responding to temperature settings or frequently cycles on and off, your thermostat might need attention.
3. What are the signs of clogged air filters?
Reduced airflow, higher energy bills, and frequent system cycling are indicators of clogged air filters.
4. Why are frozen evaporator coils a problem?
Frozen coils restrict airflow and can lead to significant damage to the compressor if not addressed promptly.
