Squealing or grinding from the blower assembly

Heating and air conditioning service built around Charleston
Serving Charleston and the wider Charleston County area, our crews carry the common failure parts on the truck — capacitors, contactors, igniters, flame sensors, motors and filters — so the first visit is usually the last one.
A large share of the equipment we service in Charleston 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.
Heating season here is December through February. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Charleston29425 HVAC questions, answered
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 Charleston 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 29425?
A diagnostic visit in Charleston 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.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in South Carolina, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
How often should I change my filter in 29425?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Charleston 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 offer maintenance plans?
We do. A two-visit plan in South Carolina 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 service commercial and light commercial properties?
Yes. Around Charleston we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
