Air Conditioning Installation, Repair, and Replacement

Quality air conditioning from TNT Heating & Air covers new installations, repairs, and full system replacements for central air conditioners throughout North Myrtle Beach. Every job starts with a Manual J load calculation, so a replacement system gets sized to the actual house, and our NATE-certified technicians handle the seasonal tune-ups that catch a weak capacitor or a dirty coil before it turns into a no-cool call in July.

North Myrtle Beach was formed in 1968, when the older beach communities of Cherry Grove, Ocean Drive, Crescent Beach, and Windy Hill merged into one city, and a good share of the housing stock near those original beach cores is decades old. Homes that sit close to the water also sit right in the path of salt-laden ocean air, which can easily corrode an outdoor condenser’s coil and cabinet faster than it would inland. An AC unit near the beach that’s pushing 12 to 15 years old is worth a hard look before another repair bill.

Furnace and Heat Pump Services

TNT Heating & Air covers gas furnace and heat pump installation, repair, and maintenance for Grand Strand homes that need real heat on the handful of nights each winter when the temperature actually drops. Because winters here are mild but not absent, we size systems to handle everyday shoulder-season demand along with the occasional cold snap, and we stock parts for both furnace and heat pump platforms so a repair doesn’t turn into a multi-day wait.

Newer North Myrtle Beach neighborhoods built around Barefoot Resort and Tidewater Plantation put larger, multi-zone homes on the market than the older cottages near the original beach communities, and those bigger, two-story houses put more demand on a heating system. A heat pump sized for one zone of a golf-course home won’t keep the upstairs comfortable on a cold January night, and that’s a sizing mismatch we run into far more often in these newer subdivisions than anywhere else in town.

Ductless Mini Split Systems

Reliable ductless system installation from TNT Heating & Air solves heating and cooling problems that standard ductwork can’t reach, such as a converted garage, a screened porch turned into a livable space, or a bonus room that never gets enough airflow from the main system.

Newer developments like Seabrook Plantation include home styles with finished bonus rooms and additions that weren’t part of the original ductwork plan. Rather than tearing into walls to extend ducts that were never sized for the add-on in the first place, a ductless unit gives that room its own thermostat and its own airflow, without touching the rest of the house.

Indoor Air Quality and Filtration

The indoor air quality equipment from TNT Heating & Air helps North Myrtle Beach homeowners deal with the humidity and allergens that a standard filter alone can’t catch.

The city’s western edge runs along the marsh at Russell Burgess Coastal Preserve on Duffy Street, and homes nearby pull in more moisture and particles through open windows and return vents than homes further from the water. The right filtration or dehumidification setup, matched to the size of the house, keeps that humidity from turning into a musty smell or a spike in allergy symptoms.

Commercial and New Construction HVAC Solutions

Commercial HVAC services from TNT Heating & Air include installation, repair, and maintenance for the offices, restaurants, and retail spaces that line Highway 17 through North Myrtle Beach. Retail growth along that corridor, including large developments like Coastal North Town Center, has added a mix of new-construction shell space and older buildings running rooftop units nobody’s touched since the original build-out, and we’re licensed and insured to handle both.

Why North Myrtle Beach Homeowners Choose TNT Heating & Air

TNT Heating & Air has been family-owned since 1990, when founder Roy Teed opened the business after training at an HVAC school in Connecticut and spending years in Florida before settling on the Grand Strand. His son Garrett has helped run the company since 2012, so a North Myrtle Beach homeowner is dealing with a name, not a call center.

In May 2026, Bryant named TNT Heating & Air to its Circle of Champions, a distinction earned by only 80 Factory Authorized Dealers across North America, and the company also holds NATE certification, ENERGY STAR new-home contractor status, ACCA membership, and Santee Cooper Trade Ally status alongside its North Myrtle Beach Chamber of Commerce and BNI memberships. Customers rate the company 4.97 out of 5, and every job, residential or commercial, starts with a Manual J load calculation instead of a rule-of-thumb equipment swap.

North Myrtle Beach Heating and Cooling Questions, Answered

Why does my heat pump run constantly without keeping my North Myrtle Beach home warm?

A heat pump that runs nonstop in the 10-to-15-year age range is often undersized for the house it’s in. It can also point to a low refrigerant charge or a failing component that’s making the unit work harder to hit the same setpoint. A load calculation and a diagnostic visit usually sort out the issue.

How do I know if my North Myrtle Beach AC needs a repair or a full replacement?

A widely used industry guideline multiplies the age of the system by the cost of the repair; if that number comes out above $5,000, replacement usually makes more financial sense than another fix. A 12-year-old AC facing a $600 repair, for example, lands well past that threshold.

Why does my outdoor AC unit near the coast in North Myrtle Beach rust or fail early?

Airborne salt settles on an outdoor unit’s coil, fins, and cabinet and speeds up corrosion in a way inland equipment never deals with. Rinsing the unit with fresh water every few weeks, keeping shrubs trimmed back for airflow, and having the coil inspected during a seasonal tune-up all slow that process down considerably.

Why does my furnace short-cycle in my North Myrtle Beach home?

Short-cycling, where a furnace turns on and off repeatedly instead of completing a full heating cycle, is usually caused by a unit that was oversized for the house, a clogged filter restricting airflow, or a failing flame sensor. A technician can typically pin down which one it is in a single visit.

Are there rebates available for a new heat pump in North Myrtle Beach?

Santee Cooper, the local electric utility, offers rebates on qualifying high-efficiency heat pumps installed by an approved Trade Ally, with amounts that scale up based on the unit’s SEER rating. TNT Heating & Air is a Santee Cooper Trade Ally, and we can confirm current rebate figures when we quote your job.

Does a two-story golf-course home in North Myrtle Beach need a zoned heating and cooling system?

Often, yes. A single-zone system sized for a smaller home tends to overcool the downstairs while the upstairs stays warm in summer and overheats the upstairs while the downstairs stays cold in winter. Zoning the system, or adding a ductless unit to the room that runs hottest or coldest, usually solves the comfort gap without replacing the whole system.

Does my North Myrtle Beach home need a whole-home dehumidifier or air purifier?

Homes near the marsh or close to the ocean deal with more humidity and airborne organic matter than homes further inland, which can show up as a musty smell, foggy windows, or worse allergy symptoms indoors. A whole-home dehumidifier or a filtration upgrade sized to the house addresses the cause rather than just masking the symptom.
