Diagnosis First
How We Find the Real Cause
Swapping parts until something works is expensive for you. A proper diagnosis follows the system step by step, from the thermostat to the outdoor unit, until the cause is clear.
- Controls: is the thermostat calling for heat or cooling, and is the signal reaching the equipment?
- Electrical: testing capacitors, contactors, fuses and motors with a meter rather than by eye.
- Airflow: filters, blower, coils and ducts. Many "broken" systems are really starved for air.
- Refrigerant: pressures and temperatures that show whether the system is charged correctly or leaking.
- Safety controls: limit switches, float switches and pressure switches that shut a system down to protect it.
You get a plain-language explanation of what failed and why, and the price, before any repair begins. See professional HVAC diagnostics.
Problems We Solve
Signs You May Need This Service
Plain-language descriptions of the situations homeowners bring to us most often.
No Cooling or Heating

Your Decision
Understanding Your Repair Estimate
A good estimate should leave you knowing exactly what you're paying for. Here's what we include, and what you should expect from any HVAC company:
- The part or problem that failed, and the symptom it caused
- Whether the failure is isolated or a sign of a bigger problem, such as a capacitor that failed because a motor is wearing out
- The total price for the repair before work starts
- Any other issues we noticed, ranked by urgency, so you can decide what to fix now and what can wait
If a repair doesn't make sense for the age or condition of the system, we'll say so. You can read more about service call and diagnostic fees and repair vs. replacement.

Safety
When to Turn the System Off and Call
Most HVAC problems are an inconvenience. A few are safety issues, and the right move is to shut the equipment off and get help:
- A burning or electrical smell from vents, the indoor unit or the outdoor unit
- A breaker that trips again right after you reset it
- A gas smell near a furnace. Leave the house and call your gas utility from outside before calling us.
- Water dripping through a ceiling or pooling near the air handler or electrical panel
- A carbon monoxide alarm. Get everyone outside and call 911.
For problems that aren't urgent, it's usually fine to leave the system off until we arrive. Our team is available 24/7; see when to call for emergency HVAC repair.
Common Questions
Straight Answers
Quick, honest answers to the questions we hear most from Mount Pleasant homeowners.
How much does HVAC repair cost?
It depends on the problem and the parts involved. We diagnose first, explain the issue, and give you the price before starting any repair.
Do you offer emergency HVAC repair?
Yes — we are available 24/7 for cooling and heating emergencies and offer same-day appointments when available.
Can you repair my HVAC brand?
We service most major makes and models of air conditioners, heat pumps, furnaces, and ductless systems.
Should I repair or replace my HVAC system?
It depends on the age, repair history, and condition of the system. A professional evaluation can help you decide.
By System
HVAC Repair by System Type
We repair every kind of heating and cooling system found in Lowcountry homes and businesses. Choose your system for details:
- Central air conditioners: AC repair in Mount Pleasant
- Heat pumps (the most common heating system in the area): heat pump repair
- Gas and electric furnaces: furnace and heating repair
- Ductless mini-splits: ductless repair and service
- Thermostats and controls: thermostat services
- Commercial systems: commercial HVAC repair
Three Quick Checks Before You Call
- Confirm the thermostat is set to the right mode (cool or heat) and temperature, and replace its batteries if the screen is dim or blank.
- Check the breakers for the indoor and outdoor units, and reset a tripped one once. If it trips again, leave it off and call.
- Replace a dirty air filter. A clogged filter causes more no-cooling and no-heat calls than almost anything else.
Still not working? Every repair starts with a diagnosis and a price before any work begins; here’s how service call fees and repair costs work.

Prevent the Next Repair
Keeping a Repaired System Running
Once a repair is done, a few habits make a second breakdown less likely:
- Change the air filter on schedule. Every one to three months is typical, more often with pets or during pollen season.
- Keep two feet of clear space around the outdoor unit and trim plants back each spring.
- Pour a cup of white vinegar into the condensate drain access a few times a year if your installer recommends it.
- Pay attention to new noises, smells or longer run times. They're early warnings.
- Schedule a tune-up before each cooling and heating season.
Regular maintenance catches worn parts before they fail on the hottest or coldest day. See HVAC maintenance.
