Why Choose Jacob Heating & Air Conditioning for HVAC Services

Rudolph Jacob started Jacob Sheet Metal Works in DeLand in 1921, and today the company is led by third-generation family member Robert Jacob. That history matters when you are handing someone the keys to your home. The family name is on the trucks, the same family answers for the work, and a business that has lasted more than a century in the county seat has had to earn repeat customers one repair at a time.

Customers back that up. We hold a 4.9 rating across more than 1,000 reviews, and our Florida contractor license (#CAC024345) has been active since 1982. For a larger project, we are also a Carrier Factory Authorized Dealer, so you can talk through new equipment with the people who will install and service it.

Air Conditioning Repair and Replacement in DeLand

When your air conditioning system blows warm air, leaks, short cycles, or simply cannot keep up, Jacob Heating & Air Conditioning diagnoses the problem, walks you through repair and replacement options, and handles installation and seasonal tune-ups. Our technicians service all makes and models, so you do not need to know the brand on your outdoor unit before you call.

DeLand homes come in every age, from older houses in the Historic District and the Garden District to rentals near the Stetson University campus and new builds out west. Before recommending equipment, we look at how the existing ducts reach each room, so a replacement is sized and set up for the house you actually live in.

Air Ducts for Older Homes, Additions, and New Builds

Your air ducts deliver cool and warm air to every room, and a torn run, a loose connection, or a poorly planned layout can leave one bedroom stuffy while the rest of the house is fine. We can inspect a duct system, seal or repair damaged sections, replace runs that have failed, and lay out new ductwork for an addition or a new build.

If you have enclosed a sunroom, finished a garage, or renovated a place near downtown, it is worth having someone confirm that the ducts serving the new space were extended properly. We can trace the run and tell you what we find, and we put any repair recommendation in plain terms.

Commercial HVAC for DeLand Businesses

Shops, restaurants, and offices in DeLand can count on Jacob Heating & Air Conditioning for commercial cooling and heating, from emergency repair to full replacement and scheduled maintenance. A broken system on a busy day costs more than comfort, so we focus on getting a clear diagnosis and a workable plan quickly.

Businesses along Woodland Boulevard, Indiana Avenue, and International Speedway Boulevard keep different hours than a typical household. We schedule work around your opening and closing times where we can, and we offer maintenance so a small problem gets caught before a customer notices it.

Ductless Systems for Rooms Without Ducts

A ductless system cools and heats a single room or zone without ductwork, which makes it a practical choice for additions, converted garages, sunrooms, and spaces that never had a duct run. We handle installation, repair, replacement, and ongoing maintenance.

In an older DeLand house where adding ducts would mean opening finished walls or ceilings, a ductless unit is often worth pricing against the alternative. We will look at the room, explain both routes, and let you compare before you decide.

Furnace Repair and Installation

Your furnace may only run a few weeks a year in Volusia County, but those are the nights you most need it. Jacob Heating & Air Conditioning repairs, maintains, and installs gas furnaces and can help you decide when replacement makes more sense than another repair.

Because a furnace sits idle for most of the year, the first cold night is a bad time to find out it will not light. Booking a heating check in the weeks before the Fall Festival of the Arts, held downtown the weekend before Thanksgiving, gets the system tested while appointments are still easy to find.

Heat Pumps for Heating and Cooling

A heat pump heats and cools your home with a single system, and Jacob Heating & Air Conditioning handles heat pump installation, repair, and maintenance. We can compare a heat pump with a conventional air conditioner and furnace setup so you can see how each fits your home.

If your older air conditioner is nearing the end of its life, a replacement project is the right time to ask about heat pump options. If you are near Stetson or just off Woodland Boulevard, give us your current equipment details and we will outline what a swap involves.

HVAC Maintenance Plans

Routine maintenance keeps your system clean, tested, and easier to repair when something wears out. Our Planned Maintenance Membership includes tiered options, with the Bronze plan covering two maintenance visits a year, and higher tiers adding benefits such as priority scheduling.

If you own a rental near Stetson or look after a few properties around DeLand, a plan puts every system on a regular schedule so you are not chasing tune-ups one address at a time. For your own home, it means a technician who already has the history of your equipment.

Indoor Air Quality

Better indoor air quality starts with the equipment that already moves air through your home. Jacob Heating & Air Conditioning can discuss filtration, air purification, and ventilation options that work with your system.

After a renovation or an addition, it is reasonable to ask what is circulating inside. We can look at your current setup, explain your options, and recommend only what fits your home.

Zone Control Systems

A zone control system adds dampers, a control panel, and separate thermostats so each part of the house can hold its own temperature. Jacob Heating & Air Conditioning installs new zoning and troubleshoots systems that are already in place.

Two-story houses, homes with converted attics, and properties with a guest cottage often have rooms that never match the thermostat in the hall. Zoning gives each area its own setting, and we can tell you whether it is a good fit for your floor plan.

HVAC Questions From DeLand Homeowners

How do I know whether to repair or replace my air conditioner in DeLand?

Look at the system’s age, how often it has needed repairs, and whether it still keeps the house comfortable. A technician can inspect the unit, give you repair and replacement costs side by side, and let you decide. Jacob Heating & Air Conditioning provides both options so you are not pushed toward either one.

Is Jacob Heating & Air Conditioning licensed to do HVAC work in Florida?

Yes. Our Florida Certified Air Conditioning Contractor license is #CAC024345. You can look it up on the Florida Department of Business and Professional Regulation website, where it shows as current and active.

Do you offer after-hours AC and heating service in DeLand?

Yes, we offer after-hours service. Call (386) 232-5888, tell us what the system is doing, and we will explain the next step. For anything that can wait, you can request service online.

Can I add air conditioning to a room in an older house without new ductwork?

Often you can, with a ductless system. It serves one room or zone without ducts, so it can suit an enclosed porch, a garage conversion, or an addition. We would need to see the space first to say whether it is the right fit.

Should I replace my air conditioner with a heat pump?

It depends on your current equipment, how you use the house, and your budget. We can price a conventional replacement and a heat pump side by side and explain how each would work in your home.

What happens during a maintenance visit?

A technician inspects and tests the major components of your heating and cooling system, looks for developing problems, and tells you what they found. The Planned Maintenance Membership schedules these visits for you so you do not have to remember.
