When your AC dies in the middle of a West Volusia July, it isn't just an inconvenience. It’s a full-blown emergency. You're sweating through your shirt, the humidity is creeping into the drywall, and suddenly, you’re staring at a search engine trying to figure out who won’t rip you off. Jacob Heating and Cooling is a name that pops up constantly if you live anywhere near DeLand, Orange City, or Deltona. They’ve been around since 1921. Think about that for a second. That’s over a century of dealing with Florida’s brutal climate.
Most people assume all HVAC companies are basically the same—some guys in a van with a manifold gauge. Honestly, that’s a dangerous way to look at it. There is a massive difference between a "parts changer" and a technician who understands the actual physics of airflow. When you’re dealing with a company like Jacob, you’re looking at a legacy that started before residential air conditioning was even a standard thing.
Why Jacob Heating and Cooling Stays Relevant After 100 Years
Survival in the service industry is hard. Survival for 100+ years is nearly impossible. You’ve seen the "Fly-by-Night" outfits that offer a $29 tune-up just to get in the door and tell you that you need a $15,000 new system. It happens all the time. Jacob Heating and Cooling has stayed in business because they realized early on that reputation is more valuable than a quick upsell.
The company is deeply rooted in the West Volusia community. They aren't some massive national conglomerate that bought out a local name; they are a family-grown operation. They focus heavily on NATE-certified technicians. If you aren't familiar, North American Technician Excellence (NATE) is basically the gold standard for HVAC certification. It means the person working on your $8,000 heat pump actually knows how the refrigerant cycle works and isn't just guessing based on a YouTube video they watched that morning.
The Real Cost of Neglect
People hate spending money on maintenance. I get it. It feels like paying for something you already have. But in Florida, your AC is essentially an engine that runs 2,500 to 3,000 hours a year. Imagine driving your car for 3,000 hours without an oil change. It would explode.
When a technician from Jacob Heating and Cooling comes out for a "Planned Maintenance" visit, they aren't just looking at the filter. They are checking the capacitance of the start components, cleaning the condensate drain line—which is the number one cause of water damage in Florida homes—and checking for "pitting" on the contactors. It’s the boring stuff that prevents the 2:00 AM breakdown.
Dealing With the "Old House" Problem in DeLand
DeLand is famous for its gorgeous historic homes. While they look incredible, they are a nightmare for modern HVAC. You have lath and plaster walls, zero attic space, and crawlspaces that would make a horror movie director jealous. This is where the expertise of Jacob Heating and Cooling really shows up.
Installing a modern, high-efficiency system in a home built in 1920 requires more than just muscle. You need to understand static pressure. If you put a high-powered blower on old, undersized ductwork, the system will literally "choke" itself out. It will be loud, inefficient, and the compressor will die in five years. Jacob’s team has decades of experience retrofitting these specific types of properties. They know how to hide ductwork in closets or recommend ductless mini-split systems when the architecture simply won't allow for traditional trunk lines.
Let’s Talk About SEER2 Ratings
You’ve probably seen the labels on the side of AC units. Since 2023, the industry moved to SEER2. It’s basically a more realistic way of measuring efficiency.

- Old systems: Often 10 or 12 SEER.
- Modern entry-level: 13.4 SEER2 (roughly 14.3 SEER).
- High-end: 20+ SEER2.
The jump from an old 10 SEER unit to a new 16 SEER2 unit can legitimately cut your cooling bill by 30% or 40%. Over a decade, that pays for the unit itself. Jacob Heating and Cooling carries brands like Carrier, which are known for their reliability in high-salt, high-humidity environments. They don't just push the most expensive unit; they look at the "Manual J" load calculation. This is a big deal. If a contractor doesn't perform a load calculation, they are guessing. A system that is too big is just as bad as one that is too small—it will cool the house too fast without removing the humidity, leaving you feeling "cold and clammy."
The Heat Pump Revolution in West Volusia
A lot of folks still think "heat pump" means "weak heat." That’s old-school thinking. Modern heat pumps are incredibly efficient, even when the temperature dips into the 30s during those weird Florida winters. Jacob Heating and Cooling has been a proponent of this technology because it eliminates the need for expensive electric heat strips to run constantly.
In a place like Orange City or Deltona, a heat pump is almost always the smartest financial move. It’s basically an air conditioner that can run in reverse. Instead of creating heat, it moves heat from the outside air into your home. Even when it’s 40 degrees outside, there is plenty of heat energy to be harvested.
Indoor Air Quality (IAQ) is No Longer Optional
Post-2020, everyone is obsessed with what’s in their air. Rightfully so. Florida is the mold capital of the world. Jacob offers solutions like UV lights and electronic air cleaners (like the REME HALO or Carrier Infinity Air Purifier).
UV lights are installed inside the air handler, right above the cooling coil. This is the wettest part of your system. By shining UV-C light on the coil, it prevents "dirty sock syndrome"—that nasty smell caused by bacterial growth on the fins. It’s not just about comfort; it’s about health. If you have asthma or allergies, these additions aren't luxuries; they are necessities.
Common Misconceptions About HVAC Repair
I hear this all the time: "I just need a little Freon."

First off, "Freon" (R-22) is essentially extinct and incredibly expensive because it’s no longer manufactured. Modern systems use R-410A, and even that is being phased out for newer refrigerants like R-454B. Secondly, an AC system is a closed loop. If it needs refrigerant, there is a leak. Adding gas to a leaking system is like putting air in a tire with a nail in it. Jacob Heating and Cooling focuses on finding the leak. Is it in the evaporator coil? The service valves? The line set? Fixing the root cause is the only way to ensure the system survives the summer.
Actionable Steps for Your Home
If you're sitting there wondering if your system is about to kick the bucket, or if you're just looking to lower your Duke Energy bill, here is what you should actually do:
- Check your "Delta T": Grab a kitchen thermometer. Measure the air temp at the intake (where the filter is) and then at the vent closest to the AC. The difference should be between 16 and 20 degrees. If it's only 10 degrees, something is wrong. Call for service.
- Look at your outdoor fins: If the "fins" on your outdoor unit are crushed or corroded, your system can't breathe. This forces the compressor to work harder, pulling more Amps and costing you more money.
- Clear the perimeter: Ensure there are at least two feet of clear space around your outdoor condenser. Hiding it behind bushes might look nice, but it’s killing your efficiency.
- Verify your warranty: If your system is under 10 years old, it likely has a parts warranty. Jacob Heating and Cooling can verify this for you. Don't pay for a motor or compressor if the manufacturer is supposed to cover it.
- Audit your thermostat: If you’re still using a "dumb" thermostat, you’re wasting money. Switching to a smart thermostat that accounts for humidity levels can save significant cash, especially if you set it to "dehumidify" mode while you're at work.
The reality of living in Central Florida is that your HVAC system is the most important mechanical component of your home. It’s more important than your water heater or your dishwasher. When it fails, life stops. Choosing a company like Jacob Heating and Cooling isn't just about getting a repair; it’s about tapping into a century of local knowledge to make sure you aren't stuck in a 90-degree living room next Tuesday.
