HVAC Services in Charleston, SC
Charleston’s unique climate challenges your HVAC systems year-round. From sweltering summers to chilly winter nights, we keep Holy City homes comfortable with honest service that treats your family like ours.
Your Lowcountry HVAC Company — Serving Greater Charleston Since 1998
Jimmy and Lorraine Blanton started this company out of Ravenel with a simple idea: treat every customer’s home the way you’d treat your own. Twenty-seven years later, their sons Aaron and Brandon run a 40-person team that covers every corner of the Charleston Tri-County area — Berkeley, Charleston, Dorchester, and Colleton Counties.
Family-owned, based on New Road in Ravenel — show up on time, tell the truth about what we find, do the work right, clean up before we leave. That approach has earned us a 4.8-star rating across more than 1,400 Google reviews. As one homeowner put it: “We’ve had Blanton’s people out for air-conditioning, heating and several plumbing problems (it’s an old house!) — they are unfailingly polite, hard-working, neat, we never have to clean up after them when they leave.”
What makes us Charleston’s go-to HVAC team
Historic home expertise
We’ve worked on everything from Rainbow Row townhouses to century-old Summerville cottages. Old wiring, tight crawl spaces, original architecture don’t slow us down.
Coastal climate specialists
Salt air, humidity, and hurricane conditions require different approaches. We know which equipment lasts in Charleston’s challenging environment.
All-neighborhood coverage
From downtown condos to West Ashley suburbs, Mount Pleasant developments to James Island waterfront homes, we know every corner of the Holy City.
Emergency response priority
When your AC dies during a 95-degree day or your heat fails on a cold January night, we make Charleston calls our top priority.
Hurricane recovery experience
We’ve helped Charleston recover from Hugo, Irma, Dorian, and countless smaller storms. We know what storm damage looks like and how to fix it.
Complete HVAC solutions
AC installation in Charleston, heating installation, air quality systems, emergency service – everything Charleston homes need under one trusted roof.
Charleston HVAC problems that need professional attention
Hurricane season preparation issues
HVAC systems struggling after storms or showing signs of electrical damage need immediate professional inspection before causing bigger problems.
Historic home humidity problems
Excessive moisture damaging original hardwood, plaster, or architectural details means your HVAC system can’t handle Charleston’s coastal climate.
Salt air corrosion damage
White buildup, rust, or deterioration on HVAC components indicates coastal air damage that spreads quickly without professional attention.
Neighborhood-specific performance drops
Downtown heat island effects, waterfront humidity, or suburban dust affecting your system’s ability to maintain comfort.
Why Charleston chooses Blanton and Sons
True local knowledge
We’ve lived through Charleston’s growth from sleepy Southern city to booming destination. We understand how the climate affects different neighborhoods.
Protect historic investments
Proper HVAC prevents humidity damage to irreplaceable architectural features in Charleston’s older homes while maintaining modern comfort.
Handle Holy City weather
From brutal summer heat to surprise winter freezes, we install and repair systems that work reliably through Charleston’s weather extremes.
Support community growth
As Charleston expands, we’ve grown with it, maintaining the personal service that built our reputation while serving more families.
Honest pricing always
Charleston neighbors deserve fair treatment. No surprise charges, no high-pressure sales, just honest work at honest prices.
Air Conditioning Services
Charleston summers are no joke. From May through October, your AC system is the hardest-working appliance in your home. We handle every aspect of residential air conditioning.
AC Repair
Same-day emergency service for breakdowns, refrigerant leaks, electrical failures, and everything in between. Our trucks carry the most common parts so most repairs get finished on the first visit.
AC Installation
New system installations sized for Charleston’s heat and humidity — proper load calculations, American Standard and Rheem equipment, and a workmanship guarantee.
AC Maintenance
Annual tune-ups that catch small problems before they become August emergencies. Jimmy’s Comfort & Care Plan members get priority scheduling and discounted rates.
AC Replacement
When repair costs no longer make sense, we’ll help you choose the right replacement system and handle the full installation.
Heating Services
Lowcountry winters are mild compared to up north, but those damp nights in the 30s and 40s are no fun without a working heater. And when that occasional hard freeze hits, you need a system that can actually keep up.
Heat Pump Installation & Repair — The most popular heating and cooling solution for our climate. Efficient year-round comfort from a single system.
Furnace Repair & Installation — Gas and electric furnace service for homes that rely on traditional forced-air heating.
Mini-Split Systems — Ideal for older Charleston homes without existing ductwork, additions, garages, and bonus rooms.
Indoor Air Quality
Charleston’s combination of pollen, salt air, and humidity creates air quality challenges that most of the country doesn’t deal with. Our air quality services include duct cleaning, dehumidifier installation, air filtration systems, and thermostat upgrades — all designed to work with your existing HVAC system.
Plumbing Services
One call handles everything. Our licensed plumbers tackle kitchen and bathroom plumbing, water heater installation and repair, repiping, gas line services, sewer line inspections, and more. Devon and Dustin recently spent two days completely redoing the plumbing in a customer’s home, and the homeowner called it an “outstanding job” — recommending them by name.
