The Charleston29412 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Squealing or grinding from the blower assembly
Breaker trips every time the system starts
Thermostat reading several degrees off from reality
Musty or burnt smell the first time the system runs
One or two rooms that never reach the set temperature
Furnace lights then shuts down after a few seconds
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.
Local homeowners often run their system harder than the design intended, especially during April through October. That accelerates wear on contactors, capacitors and blower bearings.
Heating season here is December through February. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Charleston29412 HVAC questions, answered
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Charleston, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
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.
How quickly can a technician get to Charleston?
For the 29412 service area our target response time is 90-120 minutes from the moment dispatch confirms your address. Real-world timing depends on the day — the first sustained heat or cold snap of the season is always our busiest period — but we hold technicians locally specifically so that window is achievable rather than aspirational.
How often should I change my filter in 29412?
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 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.
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.
