How We Do HVAC Differently.
Four things we do on every job. It's the reason homeowners across the Grand Strand call us when somebody else couldn't figure it out.
- 01
We measure first.
Before we quote a system, we measure your home: square footage, windows, insulation, ductwork. That way the equipment we recommend actually fits the house you live in.
- 02
We fix before we replace.
If a repair will solve the problem, that's what we'll recommend. New installs are recommended only if there is no other path forward.
- 03
We design for the coast.
Atlantic salt air, Grand Strand humidity, and vacation rentals running all summer are hard on equipment. We choose coastal-rated systems and design around those conditions on purpose.
- 04
We document every job.
After installation, you get a complete folder with install photos, equipment paperwork, warranty registration, and the load calculation. Everything you'll ever need is in one place.
Everything HVAC, under one roof.
Installs, repairs, maintenance, and the ductwork most companies skip. One locally-owned team across Little River, Calabash, and the Grand Strand.
AC Installation
Right-sized installs based on a real load calculation, not a same-size swap of the old unit.
02AC Repair
Pinpoint the failure and fix what's broken. We recommend repair before replacement whenever a repair will solve it.
03Heating Installation
Furnaces, air handlers, and heat pumps sized and configured for the Grand Strand climate.
04Heating Repair
Furnace or heat pump down? We troubleshoot the source of the failure, not just the symptom.
05Heat Pump Service
Install, repair, and tune coastal-rated heat pumps built to handle Grand Strand humidity year-round.
06HVAC Maintenance
Twice-a-year tune-ups that catch small problems before they cost you a system.
07Same-Day Service
AC out in July? Heat out in January? We respond same-day so your home doesn't sit through the weather.
08Ductwork Design & Repair
Custom duct design, airflow balancing, and leak repair to make sure every room gets the air it needs.

During a preventive maintenance service on our HVAC in a new house that we purchased a year ago, they discovered that the builder had installed an incorrect sized air hander for our home. Comfort Masters worked with the manufacturer … and installed the correct size unit. Comfort Masters is an extremely honest and professional company.

Our air conditioner wasn't working well at all, even after a different company said it was fine. … Although Alex was busy he fit us in for a second opinion. He had calibration tools and did load calculations. Far more than any other tech I'd seen. … Wish I had called him first and saved some money.
2nd Opinion · AC Repair - Google
I had another HVAC company out twice to fix a problem with a musty smell coming from the AC ductwork. I was told there was no problem and to spray Lysol into the air intake. … Alex came out and found the problem literally in seconds. The insulation was wet inside the air handler … Very happy with his service.

Alex came out, tested and replaced the capacitor in our systems compressor. He also inspected a part another company said we needed when we did not. … He got it done quickly, at a fair price.

Called to get a quote on a/c maintenance and price was the best for twice a year service … They did an amazing job cleaning the unit inside and outside and left it looking 10 times better then it was before they came. Also I appreciate them coming out after I had my original company who installed it came to do the same job but half butted it …

Got a refund on the service call. Wonderful to have honest vendors. Will use this company forever if I need service.

… he was completely honest and didnt overcharge for anything. He didnt prey on my ignorance. He educated me on how to prevent further issues and not need his services in the future. He even waved a fee that didnt solve the problem.

Comfort Master’s Tech, Cody, put in the extra effort to solve a perplexing problem. He solved a problem with my 2nd zone unit as well. He did the research, found that the unit was still under warranty, even though Comfort Masters did not make the initial sale, and saved me money on the repair! I believe I have a new HVAC company for life!

Highly recommend this company, Alex, Cody and their team are the best in this industry locally. They are no nonsense sales pitch, get to the job at hand, excellent troubleshooting professionals. Polite, respectful, clean and very reasonably priced. … So glad we did, 5 years running…

Effective, efficient, kind and courteous. He does the right thing when given conflicting information. Because he is native to this area, he is able to guide new people to other competent professionals outside of his scope of practice.

On this 90 degree day, one of our two units stopped working. We called just before 5pm and left a message. We thought we were going to have a miserable night but 10 minutes later there was a knock and the door and within 30 minutes, air was flowing again.

So grateful for Comfort Masters!! He was at my house in less than 15 minutes (on a Saturday!!) and able to fix a problem that we’ve been dealing with for years. A problem that previous companies failed to mention.

I was referred to comfort masters by a neighbor after another company failed to fix a problem with my air conditioner. Alex contacted me at the request of my neighbor and came the same day. He and his associate, Cody, identified the problem within approximately 15 minutes. … These two men worked in my attic in extreme heat without complaint.

I’m a single mom of two and when my ac went out in the dead of summer Comfort Masters went out of their way to get out to my house and got my dinosaur of a unit running. A few months later they came out and replaced my unit. … He was very professional and got everything replaced and installed in record time.

Alex came same day to evaluate my AC problem, even though I gave him the option to wait until a weekday. He installed a new AC unit within the next 24 hours, and when we were hit by a rainstorm, came back next day to double check everything was working properly.

My heat pump ceased working the first night of severe cold. Also, one of the rooms in my house never got air flow in its vent. Alex came out, diagnosed the issues … Since then, I have added a ductless system to a room and replaced my ac/heating system. Once again, Comfort Masters has come through with great pricing, superior service in every way.

Our old HVAC unit wasn’t cooling our home and was struggling to keep up. Alex is very knowledgeable and was able to get us the right size unit for our home. Not only does our new unit keep us cool, it keeps the humidity at the right levels and lowered our electric bill!

Real photos from real second-opinion HVAC calls in Little River, Calabash, North Myrtle Beach, Sunset Beach, Ocean Isle, Loris and the rest of the Grand Strand. Every case fixed.
found & fixed
-
Case 01 / 15 Little River, SC Two companies missed this. The zoning dampers had been left closed.
A homeowner had weak airflow for months. Two HVAC companies couldn't figure out why. We opened the assembly and the dampers were sitting closed, choking off air to that zone. A simple check before condemning equipment.
What we did Repositioned the dampers and verified the zone controller. No new equipment, no big repair bill.
-
Case 02 / 15 Little River, SC Same job, different angle.
A second view shows how restricted things were. The home was cooling unevenly because air physically couldn't reach part of the system.
What we did Re-verified the dampers and confirmed even cooling across every zone before leaving.
-
Case 03 / 15 Calabash, NC Duct collar installed backwards.
The original installer flipped a duct collar. Eventually the duct gave up and fell off. The system was dumping cooled air straight into the attic for who knows how long.
What we did Reseated the collar the correct way and resealed the connection with mastic.
-
Case 04 / 15 North Myrtle Beach, SC Fresh air intake tied straight to return. No ERV.
Another company added a fresh air duct directly into the return without an ERV. In our coastal humidity, that isn't fresh air. That's a moisture problem, and the AC pays for it every cycle.
What we did Corrected the ventilation setup so the home gets fresh air without the humidity penalty.
-
Case 05 / 15 Sunset Beach, NC Condensate lines left uninsulated.
A pump in an attic with bare lines and visible water staining on the framing below. Insulation prevents the sweat, sweat drips, drips become ceiling damage.
What we did Wrapped the lines and stopped the leak before any drywall came down.
-
Case 06 / 15 Cherry Grove, SC A quarter of the coil capped off.
Running with ~25% of the evaporator coil blocked at the duct connection. The homeowner was paying for efficiency they weren't getting.
What we did Rebuilt the connection so the full coil could do its job.
-
Case 07 / 15 Loris, SC Passed inspection. Still against code.
Romex running into the panel with no connector or bushing. Abrasion risk over time, fire risk over a longer time. Passing inspection and being done right aren't the same thing.
What we did Installed the proper Romex connector.
-
Case 08 / 15 Ocean Isle Beach, NC No service disconnect at the outdoor unit.
Installed without a service disconnect at the equipment. Means the system can't be safely de-energized for service. Against code.
What we did Added a proper weather-rated disconnect at the unit.
-
Case 09 / 15 Longs, SC Over-engineered attic airflow that still didn't work.
A new-construction home where the original contractor over-engineered an attic airflow setup that still didn't solve the homeowner's comfort issue. A properly installed attic fan would have done the job for a fraction of the cost.
What we did Got the home actually breathing the way it should, without the complexity.
-
Case 10 / 15 Myrtle Beach, SC Loose low-voltage wiring and moisture under the air handler.
Control wires hanging loose with no junction box. Lineset penetration packed with crumbling spray foam that already let moisture through. Visible mold staining on the ceiling around the unit.
What we did Terminated the wiring properly, resealed the penetration with mastic, and stopped the moisture intrusion before it spread further.
-
Case 11 / 15 North Myrtle Beach, SC Goodman condenser on a makeshift wood platform.
Hand-built 2x4 platform strapped down with cable, sitting directly on shingles. No roof curb, no vibration isolation, no chance in a real coastal wind event.
What we did Relocated the unit to a code-compliant pad and rebuilt the lineset run.
-
Case 12 / 15 Ocean Isle Beach, NC Wires forced through bare sheet metal.
High-voltage, low-voltage, and a refrigerant line all forced through the same unprotected opening. The cut edge of the metal will eventually wear through the wire jackets.
What we did Separated the runs into proper penetrations and added the bushings that should have been there from day one.
-
Case 13 / 15 Cherry Grove, SC Romex pulled through a wall, then painted over.
No connector, no wall plate, painted over during finish work. The cable jacket was already showing wear at the penetration.
What we did Added the proper connector and a clean wall plate so the cable isn't chewed by every vibration of the system.
-
Case 14 / 15 Sunset Beach, NC Years of biofilm sludge in a "maintained" drain line.
What came out of the condensate drain after the previous company had been doing the homeowner's annual maintenance. Should have been flushed every visit. Wasn't.
What we did Cleared the line, treated the system, and got the pan flowing before it backed up into the home.
-
Case 15 / 15 Loris, SC Heat pump iced solid. Failed defrost board.
Another company couldn't pin down why the unit kept icing over. Defrost board failed, outdoor coil iced solid, system stopped transferring heat into the home. Winters here are real.
What we did Diagnosed the failed board, replaced it, thawed the unit, got the home heating again.
