AC Repair Across Volusia, Flagler & Putnam County, FL
Air Conditioning Repair Service for Daytona Beach, Palm Coast & DeLand
A hot house and a silent AC unit do not mix well in Florida. Whether your system is blowing warm air, running nonstop without cooling the house, or making a noise you have never heard before, you need someone who can find the real problem fast. SIMS Heating and Cooling repairs AC systems for homes and light commercial properties across Volusia, Flagler, and Putnam County, and we tell you what is actually wrong before we tell you what it costs.
LET’S GET YOUR COMFORT BACK
When Your AC Stops Working Right
A lot of families call us after another company told them they needed a whole new system, when all they needed was a repair. That is not how we work. We check the system, explain what we find, and recommend a repair whenever a repair makes sense. Fix it first is not a slogan here. It is the reason people call us back.
We serve homeowners and light commercial properties throughout Palm Coast, Daytona Beach, DeLand, Deltona, Ormond Beach, and the rest of Flagler, Volusia, and Putnam County. When you call, you speak with someone who understands HVAC, not a script reader working through a queue.
Steve has worked in HVAC since 1997, and Spencer brings an aircraft mechanic’s attention to detail from his time at Embry-Riddle. Between them, SIMS brings more than fifty years of combined experience to every repair call, which matters when the difference between a $200 fix and a $2,000 mistake often comes down to correctly diagnosing the problem the first time.

Signs Your AC Needs Repair
AC Not Blowing Cold Air
Warm air from the vents usually points to a refrigerant issue, a failing compressor, or a thermostat problem. We test each before guessing, since the wrong assumption here can lead to paying for a repair that doesn’t actually fix anything.
AC Running But House Won't Cool Down
Often a dirty filter restricting airflow, or a system that is undersized or losing capacity and struggling to keep up on hot afternoons. Sometimes it’s a ductwork issue rather than the unit itself, which is why we check both.
AC Unit Frozen Over
Ice on the coil usually means restricted airflow or low refrigerant. Running a frozen system longer can damage the compressor, so this one is worth a same-day call rather than waiting to see if it thaws on its own.
AC Leaking Water Inside
A clogged condensate drain or a cracked drain pan is the usual cause. Left alone, it can lead to water damage inside the house, so it’s worth addressing quickly, even if the AC still seems to be cooling fine.
Weird Smell From AC Vents
A musty smell often points to moisture or mold in the ductwork. A burning smell means stop the system and call us right away, since that can signal an electrical issue rather than a routine repair.
AC Breaker Keeps Tripping
This can mean an electrical short, a failing capacitor, or a compressor drawing too much current. It is not something to keep resetting and hoping it stops, since repeated tripping usually means the underlying problem is getting worse.
Types of AC Repair We Handle
Compressor Repair
The compressor is the heart of the system. We diagnose whether it needs repair or whether the cost of a compressor repair makes replacement the smarter call.
Refrigerant Leak Repair
We locate the leak, repair it properly, and recharge the system to the correct level instead of just topping it off.
Capacitor Replacement
A failed capacitor is one of the most common reasons an AC won’t start. It is usually a same-visit fix.
Electrical & Control Repairs
Faulty wiring, failed relays, and thermostat issues can all stop a system that is otherwise in good shape.
Benefits of Professional AC Repair
An Honest Second Opinion
If another company told you that you need a full replacement, we will inspect the system ourselves and tell you honestly whether a repair is still on the table.
Prevent a Bigger Failure
A small part failing today, like a capacitor or contactor, can take down a compressor if it is ignored. Catching it early is almost always the cheaper path.
Restore Full Efficiency
Airflow and refrigerant problems do not just stop cooling. They make the system work harder than it should. Airflow problems alone can reduce a system’s efficiency by up to 15 percent.
Direct Access to a Technician
When you call, you speak with someone who understands HVAC. No call center, no relay, no guessing who is actually coming to your house.
A Guarantee That Backs the Work
Every repair is backed by our one-year labor guarantee and 100% satisfaction guarantee. If something is not right, we make it right.
What AC Repair Includes
Every repair call starts the same way. We inspect the system, explain what we find in plain language, and go over your options before any work begins. That means diagnosing the actual cause instead of guessing, giving you a clear price before we start, completing most repairs in a single visit when parts are on hand, and standing behind the work with our labor guarantee.
Repair costs vary depending on what is actually wrong, so we will not quote a number until we have looked at your system. What we can promise is that you will know the price before you decide anything, and that we will explain the diagnosis in language that makes sense, not a list of part numbers you have to take on faith.

Hear It From Your Neighbors
Highly recommend! Spencer quickly came out and diagnosed my problem and even went the extra step to look into warranty after the company that put the unit in would not look into anything for me. Very knowledgeable and fairly priced. I’ll contact them from here on out for all my AC needs!
- Ashton Cassidy
SIMS Heating and air installed a new unit for me last year. My A/C unit had quit and the well known carrier that i had bought the Carrier unit from wouldn’t even return my call, after being a customer for over 12 years. SIMS came through with excellent service and a great new unit.
- Robertson
My elderly mother’s 20 plus year old A/C unit decided to stop cooling. After calling some of the other A/C business, she was told there would be over a week wait. She gave SIMS a call and they had someone out that evening squeezing her in. Fantastic service and great people!
- HL Smith
If moving into a new home is not stressful enough, a finicky A/C unit added to the anxiety. Fortunately, Sims came to the rescue. Instead of the giving me the usual grunts and groans and quotes for a new unit, I got quick, efficient service that solved the problem right away.

Great experience. Fast reliable service. A/C system went down and the next day they were here to replace my system. Great pricing too. I have used them for A/C maintenance as well. Knowledgeable and friendly staff and on time. Lucky to find them.

AC Repair Questions
How much does AC repair cost in Florida?
It depends on what’s wrong. Some fixes, like a capacitor, are inexpensive. Others, like a compressor, cost more. We diagnose first and give you a price before any work begins, so you’re never guessing what a repair will run.
Can you fix my AC the same day?
Often, yes, especially if the part is one we carry on the truck. If it needs to be ordered, we will tell you honestly what the timeline looks like instead of leaving you guessing.
Should I repair or replace my AC?
It depends on the age of the system, the cost of the repair, and how often it has broken down. We will lay out both options honestly instead of pushing you toward the more expensive one, since a repair is often the right call.
Do you offer a free second opinion?
Yes. If another company quoted you for a full replacement, we will take a look and tell you honestly if a repair is still a real option, no obligation either way.
Do you repair AC systems for businesses too?
Yes. We handle AC repair for light commercial properties as well as homes, using the same fix-it-first approach and the same straight answers.
