The Charleston29407 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.

One or two rooms that never reach the set temperature
Thermostat reading several degrees off from reality
Furnace lights then shuts down after a few seconds
Skyrocketing utility bills with no change in usage
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.
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.

Charleston29407 HVAC questions, answered
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.
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.
Are your technicians licensed and insured?
Every technician dispatched into Charleston is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
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.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
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.
