Best HVAC Companies in DeLand, Florida

What reviewers mention: heat pump installations, duct work replacement, thermostat installations, courteous technicians.

Jacob Heating & Air Conditioning holds the top spot on this list with a 4.9 Google rating drawn from 1,085 reviews, by far the largest review count of any HVAC company on this page. That mix of a near-perfect average and a review base in four figures is what earns it number one under our scoring, which weighs both the rating and how many people stand behind it. The company runs deep in DeLand as well: its own site states it has operated since 1921, a figure Google's local listing backs up, and our scoring rewards that verified longevity. Reviewers point to heat pump installations, ductwork replacement, thermostat work, and courteous technicians. Its shopfront sits on East International Speedway Boulevard, a genuine local storefront rather than a regional operator routing calls in. The state contractor license, CAC024345, was current and active when we checked on July 8, 2026. Get the job's scope and price in writing before work starts.

What reviewers mention: generator maintenance, generator installation, courteous technicians, thorough service.

Second place goes to Rack Air, whose 4.7 Google rating rests on 427 reviews, the second-largest review count on this page. It sits ahead of three companies holding a perfect 5.0 average, and the honest reason is our scoring, which weighs review volume and verified longevity alongside the rating. Rack Air carries more than double the reviews of any 5.0-rated company here, and its own site puts it in business since 1994, roughly 32 years, enough to max out the longevity our formula counts. Reviewers highlight generator maintenance and installation along with thorough, courteous service, so it is worth a look if you want standby power handled as well as cooling. The company is based on North Woodland Boulevard in DeLand. The state license behind it, CAC049267, held under Rack Electric, LLC, read current and active on July 8, 2026. Volume and years, not a higher rating, are why it outranks several five-star names here, and we would rather show you that math.

What reviewers mention: new unit installations, fair pricing, late-hours availability, knowledgeable technicians.

Master,Inc. ranks third and is the highest-placed of the three companies here holding a perfect 5.0 Google rating, earned across 195 reviews, the most of any 5.0-rated company on this page. It lands behind Jacob and Rack Air rather than above them because our scoring also weighs review volume and verified longevity, and while 195 reviews are strong, they trail the two leaders. No founding year we could verify turned up, so its years in business could not weigh in its favor. Reviewers mention new-unit installations, pricing they found fair, late-hours availability, and knowledgeable technicians. It operates from North Delaware Avenue in DeLand, and a separate DeLand address on Mercers Fernery Road appears on its state record. The contractor license, CAC1816544, showed current and active on July 8, 2026. A perfect average over 195 reviews is a real signal; still, skim a handful before you commit.

What reviewers mention: diagnostic service, ac cleaning service, attic hvac work, seasonal checkups.

Best Chance Air Services ranks fourth on a perfect 5.0 Google rating across 120 reviews. It lands just behind Master,Inc. because both hold a flawless average, and the tiebreaker in our scoring is review volume, where Master's 195 reviews edge Best Chance's 120. Customers write up diagnostic visits, AC cleaning, attic work, and seasonal checkups, which points to a company at ease with maintenance and tune-ups as much as repairs. Its listed address is on Lake Drive in DeLand. We could not confirm a founding year from a source we accept, so we left years in business empty rather than print a number we cannot stand behind. Without a confirmed opening date, longevity cannot count in its favor, which is part of why a spotless score lands fourth rather than higher. State contractor license CAC1822887 was active and current on our July 8, 2026 check. Skim the recent reviews for jobs like yours, and pin the scope and price down in writing first.

What reviewers mention: duct work, air handler repair, mobile home hvac service.

Denova Air takes fifth, its perfect 5.0 Google rating built on 106 reviews. It sits just below Best Chance Air Services by a narrow margin: both hold a 5.0 average, and Best Chance's 120 reviews slightly outweigh Denova's 106 in our scoring. The review topics we could pull were thin, pointing mainly to ductwork, air handler repair, and mobile home HVAC service, so we describe those plainly rather than reading specialties into a small sample. It runs from South Florida Avenue in DeLand, an address confirmed across its Google listing, its Sunbiz filing, and a contractor records database. The founding year stayed unconfirmed, so we cannot credit it for time in business. The state contractor license, CAC1821754, read as active and current on July 8, 2026. For a smaller operator, a spotless 106-review record is a solid sign in its own right.

What reviewers mention: prompt arrival, quick diagnosis, professional technicians, timely service.

Ga-Ter Air Inc. ranks sixth on a 4.8 Google rating across 99 reviews. That average lands just under the three perfect scores above it, and with a similar review count, the small rating gap is enough to place it here under our scoring. Reviewers consistently mention prompt arrival, quick diagnosis, professional technicians, and timely service, the marks of a company that shows up when it says it will. You will find it on West New York Avenue in DeLand, and its own site self-discloses the license number we verified. That license, CAC045900, was active and current as of July 8, 2026. Its founding year never checked out, so there were no years to credit. A 4.8 average across 99 reviews is a dependable record; read a few of the recent ones to see whether its strengths match your job.

What reviewers mention: thermostat repair, duct work repairs, fair pricing, quick response.

Legacy Air Conditioning rounds out this list at number seven on a 4.7 Google rating from 86 reviews. It lands last here on the two signals our scoring weighs most after the rating: at 86, it carries the fewest reviews on the page, and we could not verify a founding year, so it earns no credit for time in business. That is the honest math behind the position, not a knock on the work. The write-ups describe thermostat repair, ductwork repairs, pricing they found fair, and quick response times. The company keeps a suite on South Woodland Boulevard in DeLand. Its state contractor license, CAC1816533, came back current and active on July 8, 2026. A 4.7 average across 86 reviews is a steady record, so read the recent ones for how it handles a job that runs into trouble, confirm insurance directly, and put scope and price in writing before anyone begins.
