Outdoor condenser humming but the fan not turning

Heating and air conditioning service built around Saint Helena Island
Most of the work we do in Saint Helena Island starts the same way: the system is running but the house is not comfortable. Before we replace anything, we measure airflow, static pressure and temperatures so you are paying for the actual fault.
A large share of the equipment we service in Saint Helena Island was installed by a builder to a minimum spec. That usually means an undersized return, a cheap filter rack and a condenser sitting close to a wall.
We recommend two maintenance visits a year in South Carolina: one before April through October and one before December through February. It is the single highest-return thing a homeowner can do for equipment life.

Saint Helena Island29920 HVAC questions, answered
What does a new system cost in Saint Helena Island?
A complete residential replacement in the 29920 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.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Saint Helena Island we see algae and dust clogging drain lines constantly during April through October. It is a fast fix but ignoring it ends in ceiling damage.
How much does an HVAC service call cost in 29920?
A diagnostic visit in Saint Helena Island typically runs $75 to $150, and that fee is usually applied toward the repair if you approve the work. Repair prices are quoted as a flat rate before we start, so the number you approve is the number you pay regardless of how long the job takes.
Are your technicians licensed and insured?
Every technician dispatched into Saint Helena Island is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
How often should I change my filter in 29920?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Saint Helena Island with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in South Carolina 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.
