About HVAC service in New Castle

New Castle HVAC questions, answered
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Are your technicians licensed and insured?
Every technician dispatched into New Castle is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
Do you offer maintenance plans?
We do. A two-visit plan in Delaware covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Delaware is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
What does a new system cost in New Castle?
A complete residential replacement in the 19720 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
