⚠️ Call Us If You Notice:

🔊

Unusual Noises: Grinding, squealing, banging, or rattling sounds indicate mechanical problems

🌡️

Inconsistent Temperatures: Hot/cold spots or failure to reach thermostat settings

HVAC Service FAQs

How quickly can you respond to HVAC emergencies in Wilmington?

With two locations—our Wilmington headquarters and Castle Hayne office—we typically respond to emergencies within 1-2 hours throughout New Hanover County. We offer true 24/7 emergency service including nights, weekends, and holidays. Nobody should suffer without AC in a Wilmington summer or heat during a cold snap.

What are signs my HVAC system needs repair?

Common warning signs include: unusual noises (grinding, squealing, banging), inconsistent temperatures or hot/cold spots, weak airflow from vents, higher than normal energy bills, frequent cycling on and off, strange odors when the system runs, visible leaks or moisture around equipment, and failure to reach thermostat settings. If you notice any of these, call for a diagnostic inspection.

How often should I have my HVAC system serviced?

We recommend bi-annual maintenance—once in spring for your AC and once in fall for heating. In coastal North Carolina’s demanding climate, regular maintenance is essential to prevent breakdowns, maintain efficiency, and extend system life. Our maintenance plans include both seasonal tune-ups plus priority scheduling and repair discounts.

Do you repair all HVAC brands?

Yes! Our NATE-certified technicians are factory-trained on all major brands including Trane, Carrier, Lennox, Goodman, Rheem, York, American Standard, Bryant, and Mr. Cool. Whether your system is brand new or decades old, central AC or ductless mini split, we have the expertise to diagnose and repair it.

How much does HVAC repair cost?

Repair costs vary based on the specific problem and parts needed. We provide upfront pricing before any work begins—no surprises. Our diagnostic fee is applied toward repairs if you proceed. For transparent pricing and to avoid unexpected repair costs, consider our maintenance plans which include discounts on repairs.

What’s included in an HVAC maintenance visit?

Our comprehensive maintenance includes: inspection of all components, cleaning coils and drain lines, checking refrigerant levels, testing electrical connections, lubricating moving parts, calibrating thermostat, inspecting ductwork, replacing standard filters, testing safety controls, and providing a detailed system report with recommendations.

When should I repair vs. replace my HVAC system?

Consider replacement if: your system is 10-15+ years old, repair cost exceeds 50% of replacement cost, the system uses R-22 refrigerant (phased out), or you’re experiencing frequent breakdowns. We provide honest assessments—if repair makes more sense, we’ll tell you.

Do you offer HVAC maintenance plans?

Yes! Our maintenance plans include bi-annual tune-ups (spring AC, fall heating), priority scheduling for repairs, discounts on repairs and parts, no overtime charges for after-hours calls, and extended equipment life. Plans typically pay for themselves by preventing just one costly breakdown.
