Commercial HVAC Services in Deltona & Central Florida

Light commercial cooling for Central Florida businesses

For a business, a broken air conditioner is never just a comfort problem. It is a dining room that empties out, a full day of appointments that has to be rescheduled, customers who walk out of a hot store and never mention why, and staff trying to work in Florida heat. Every hour the system is down has a number attached to it.

Synergy Heating & Cooling Inc. provides commercial and light commercial HVAC service to businesses across Central Florida. We are a family-owned shop based in Deltona, led by licensed Florida HVAC contractor Roy James Durkee II (License CAC1820583) — which means the person whose license is on the work is the person invested in getting your building back up.

We handle the systems most small and midsize businesses actually run — split systems, packaged units, and ductless mini-splits, across all major brands including Ruud, Carrier, Trane, Goodman, and Lennox.

Commercial AC repair. Fast diagnostics and honest options when a system goes down, with same-day and after-hours availability.

Preventive maintenance. Scheduled visits that catch weak parts while they are still cheap to replace, with every unit documented visit to visit.

System replacement and installation. Free estimates on new installations, properly sized to the building rather than copied off the old nameplate.

Ductwork and indoor air quality. Duct repair, sealing, and cleaning, plus indoor air quality improvements for spaces where air matters as much as temperature.

Dental and medical offices. You cannot reschedule a full day of chairs. These spaces need steady temperature and humidity, and staff working under lights in PPE feel a drifting system within the hour.

Restaurants, cafés, and bars. Kitchen equipment dumps heat into the building all day, so the cooling load is nothing like an equivalent office.

Salons and barbershops. Dryers and processing lamps concentrate heat into a small footprint, and chemical fumes make ventilation a real concern.

Retail shops and boutiques. A hot store loses sales quietly — customers leave and nobody ever blames the AC.

Churches and worship centers. A tough intermittent load: a full sanctuary for a few hours a week and near-empty the rest of the time.

Office parks and multi-tenant suites. Several units of different ages and brands under one roof, with one owner or property manager fielding every complaint.

Warehouses and light industrial. Ventilation and heat-stress concerns for staff through a Florida summer, plus protecting whatever is stored inside.

In April 2026 our team spent most of a day at a dental practice with six separate split systems serving different zones of one building. We cleaned and inspected coils on all six, replaced eight 20x20x1 filters building-wide, tested and tightened contactors, capacitors, and wiring connections on every unit, verified refrigerant circuits with gauges, and cleared and treated the condensate drains.

One of those systems runs R-454B, the low-GWP refrigerant the industry is transitioning to. Different refrigerant, different targets — our instruments and training are already there.

We wrote the whole visit up, photos included: read the full commercial maintenance job report. That job was on Merritt Island, at the far edge of our service area — we travel for the right commercial client, and the same standards apply whether the building is in Deltona or two counties away.

The most expensive commercial HVAC failure is the one nobody saw coming. Scheduled maintenance turns unpredictable breakdowns into a predictable line item, keeps every unit documented visit to visit, and catches weak parts while they are still cheap to replace. One planned visit beats one unplanned closure — every time.

We offer customized maintenance schedules for offices, retail spaces, restaurants, and more, and we work around your hours rather than through them. For a restaurant that means before the lunch rush, not during it. For a dental office it means the day the chairs are empty.

Regular commercial maintenance helps you minimize downtime, maintain comfortable indoor environments, protect temperature-sensitive equipment, and control operating costs.

The license holder is involved in the work. We are a small, family-owned shop — not a dispatch center with a rotating roster. The same technicians come back, learn your equipment, and remember the awkward ductwork over the back office.

We actually name where we work. Deltona, DeLand, Sanford, Orange City, Lake Mary, and Daytona Beach are our neighbors, not a vague radius around a city an hour away.

Honest recommendations. We tell you when a repair makes more sense than a replacement, and we put your options in writing so you can plan a capital expense instead of being surprised by one.

Most HVAC companies will not put a number on their website. We do.

Diagnostic visit: $125. A technician comes out, finds the actual problem, and explains your options before any work begins.

HVAC tune-up: $95. A full maintenance visit — measurements and testing, not a rinse and a sticker.

Free estimates on new installations. No charge to have us evaluate a replacement and put written options in front of you.

Buildings with multiple systems are quoted based on how many units are involved and what each one needs. Call 407.412.7188 and we will give you a real number before we come out.

Cooling does not fail politely at 10:00 on a Tuesday morning. It fails on a Saturday in August with a full dining room, or overnight before a building full of patients arrives.

We are open 24/7 for emergency repairs across our Central Florida service area. If your building is down, call 407.412.7188 and talk to a local shop that can actually get someone out.

A commercial system replacement is a real capital decision, and it rarely happens on a convenient schedule. We offer commercial HVAC financing for businesses and property management groups, so a failed system does not have to become an emergency withdrawal.

You can see your options on our financing page, including prequalification that does not affect your credit.

We serve commercial customers throughout Volusia, Seminole, Orange, Lake, Flagler, Brevard, Osceola, and Marion counties — roughly a 60-mile radius from our Deltona shop, reaching from Orlando to Daytona Beach and Ocala.

That includes Deltona, DeLand, Sanford, Orange City, Lake Mary, DeBary, and Daytona Beach, plus the surrounding communities. If you are not sure whether your building is in range, call 407.412.7188 and ask — the answer is usually yes.
