Heating and AC Repair FAQs

How do I know if my HVAC system needs repair?

You should call a professional if you notice

  • Uneven heating or cooling in rooms
  • Strange noises such as buzzing, rattling, or banging
  • Higher than usual energy bills
  • Frequent cycling on and off
  • Poor airflow from vents

How do I know if my HVAC system needs replacement?

If your system is over 10–15 years old, requires frequent repairs, or uses R-22 refrigerant (which is phased out and expensive), replacement is often more cost-effective. A good rule of thumb is the "5,000 Rule": multiply the age of the unit by the repair cost. If the total exceeds $5,000, it’s time to replace.

How often should I have my HVAC system serviced?

Twice a year—once before cooling season and once before heating season—to maintain efficiency and prevent breakdowns.

Do you offer 24/7 emergency HVAC services?

Yes. Our team is ready for same-day emergency repairs to restore comfort and prevent damage.

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 can quickly identify the root cause to prevent further damage to the compressor.

Can you help improve indoor air quality?

Yes. We provide air purifiers, humidifiers, ventilation solutions, and duct cleaning to reduce allergens, pollutants, and humidity issues.
