Restaurants, bars, motels, medical facilities, and commercial buildings. We design, install, and service commercial HVAC systems built for continuous operation — not residential systems pushed past their limits.
Commercial HVAC isn't just a bigger residential job. The equipment is different, the load calculations are different, the code requirements are different, and the stakes are higher. A restaurant losing AC on a Saturday night in July doesn't just mean uncomfortable diners — it means health code issues, potential closure, and real revenue loss. A motel with failed AC in individual rooms gets bad reviews and refund requests before the technician can even park.
We understand this. We've worked in commercial kitchens, bars, motel corridors, and medical facilities. We know what continuous operation means for maintenance intervals and component life. We bid commercial work with real load calculations, proper equipment specifications, and honest timelines — not residential rule-of-thumb estimates scaled up.
Cozy AC and Heating is currently active in the commercial HVAC market, including bidding work at a veterans hospital facility in the Sarasota area. That level of project requires insurance, licensing, technical capability, and the ability to work within facility requirements. We have all of it.
Restaurants are among the most demanding HVAC environments that exist. A full-service kitchen generates enormous heat loads from cooking equipment — ranges, fryers, ovens, and steamers — that have to be continuously exhausted and replaced with conditioned makeup air. Meanwhile, the dining room needs to stay comfortable for guests regardless of what's happening in the kitchen.
Florida health code and fire code require properly engineered exhaust systems over cooking equipment. The exhaust hood removes heat, smoke, grease-laden vapor, and combustion gases. Makeup air systems replace the exhausted air — if you don't replace it, you create negative pressure that makes doors hard to open and pulls unconditioned air through every gap in the building envelope. We design and install exhaust and makeup air systems that balance properly and meet code.
Restaurant HVAC equipment — especially rooftop units near kitchen exhaust — accumulates grease much faster than residential equipment. Grease-coated condenser coils lose efficiency rapidly and become fire hazards. Commercial restaurant HVAC maintenance schedules need to account for this. We inspect and clean commercial equipment on schedules appropriate for the type of operation, not generic residential intervals.
A restaurant AC system runs during service, often 12–16 hours a day, 365 days a year. Equipment selection for restaurant applications needs to account for this duty cycle. We specify commercial-grade equipment rated for continuous operation, not residential or light-commercial units that will fail under restaurant conditions.
Bars and nightclubs present a different set of challenges than restaurants. High occupancy loads — a crowded bar on a Friday night can have 5–10 times the number of people per square foot that a typical commercial building is designed for — generate massive sensible and latent heat loads. Add to that late operating hours, significant lighting heat (especially older fixtures), and often poor original HVAC design, and you have a situation that demands a system sized and designed specifically for peak occupancy.
Undersized bar HVAC is extremely common. Many bar owners are living with a system that worked fine when the building was an office and has been struggling since the conversion. We assess actual peak loads, not just square footage, and design accordingly. Sometimes the answer is additional capacity and better distribution. Sometimes it's fixing duct design that's creating dead zones while overcooling other areas.
Hospitality properties have a requirement that most commercial buildings don't: individual room control. Guests expect to set their own thermostat, and a property where the AC "runs on a schedule" or can't be individually controlled gets reviews that reflect it.
Most motels use packaged terminal air conditioners (PTACs) — the through-wall units common in hotel rooms. These require regular filter cleaning, coil inspection, and drain pan treatment to operate reliably. When PTACs fail, they need quick replacement to avoid turning a maintenance issue into a guest complaint. We stock common PTAC sizes and can typically replace a failed unit same-day or next-day.
For motel renovations or new construction, ductless mini-splits are increasingly the preferred option — they're more efficient than PTACs, quieter, and give guests better control. We install multi-zone mini-split systems designed for hospitality applications.
Beyond individual rooms, motel properties need cooling for lobbies, corridors, laundry facilities, and utility spaces. We design and maintain these systems as part of a complete property HVAC plan.
Medical facilities — clinics, surgical centers, dental offices, and larger healthcare campuses — operate under specific ventilation and air quality requirements that go well beyond standard commercial HVAC. Florida building code for healthcare occupancies references ASHRAE 170, which specifies minimum outdoor air rates, pressurization relationships between spaces, filtration requirements, and temperature/humidity ranges for different areas.
Surgical and procedure areas require specific air changes per hour and filtration levels. Waiting rooms need to maintain positive or negative pressure relative to adjacent spaces depending on infection control design. Sterilization areas need specific humidity control to protect equipment and supplies.
We have experience in healthcare HVAC and understand these requirements. Our current work includes bidding a veterans hospital project — the documentation, licensing, and technical requirements for that level of project reflect our capability in this sector.
Commercial office buildings typically use rooftop packaged units or split systems serving VAV (variable air volume) or constant volume distribution systems. We handle rooftop unit replacement, ductwork modifications for tenant buildouts, and ongoing maintenance contracts for office buildings across Sarasota and surrounding areas.
