Light Commercial HVAC Services Across Volusia, Flagler & Putnam County, FL
Commercial AC Repair & Installation for Northeast Florida
Before SIMS Heating and Cooling repaired a single home AC unit, the team behind it was keeping commercial equipment running for grocery stores and apartment complexes. That background shows up in how we handle light commercial HVAC today: rooftop units, office systems, and retail spaces across Volusia, Flagler, and Putnam County, serviced by people who understand what happens to a business when the air conditioning goes down.
LET’S GET YOUR COMFORT BACK
Commercial HVAC Built on Industrial Roots
SIMS started as Southern Industrial Maintenance Solutions, keeping cardboard balers, trash compactors, and other equipment running for commercial properties long before the HVAC side of the business existed. That experience with commercial equipment is part of the foundation this company was built on, not a side offering added later.
Today, that means we handle rooftop units up to 25 tons, office and retail AC systems, and HVAC maintenance contracts for businesses across Palm Coast, Daytona Beach, DeLand, Deltona, Ormond Beach, and the rest of our coverage area.
A lot of HVAC companies treat commercial work as an occasional add-on to residential business. For SIMS, it’s closer to the opposite: the industrial and commercial maintenance background came first, and the residential side grew alongside it.

Signs Your Business Needs HVAC Service
Rooftop Unit Not Cooling
A rooftop unit struggling in Florida heat affects both comfort and, depending on your business, your inventory or equipment, so it’s worth a prompt call rather than waiting it out.
Uneven Temperatures Across the Space
Common in retail and office layouts where the system was sized for a different floor plan than what’s there now, especially after a renovation or tenant change.
Rising Utility Costs
A commercial system losing efficiency often shows up in the utility bill before it fully fails, which makes an early inspection worth the visit.
Frequent Breakdowns
Repeated service calls on the same unit usually mean it’s time to weigh repair costs against replacement, especially for equipment nearing the end of its expected life.
No Maintenance History
If nobody can tell you when the system was last serviced, that’s reason enough for an inspection before it becomes an emergency during business hours.
Aging Equipment Nearing End of Life
Commercial downtime costs more than a home AC failure. Planning replacement before a full breakdown protects your business from an unplanned closure.

Benefits of a Commercial HVAC Partner
Less Downtime
A business without working AC is a business losing customers, comfort, or productivity. A fast response limits the damage before it costs you more than the repair itself.
A Team That Understands Commercial Equipment
Our roots are in industrial and commercial equipment maintenance, not a residential company that occasionally takes commercial calls when asked.
Predictable Costs Through a Maintenance Contract
A service agreement turns surprise repair bills into planned maintenance costs, which makes budgeting easier for any size business.
Straightforward Communication
When you call, you speak with someone who understands HVAC and can explain the issue in terms that make sense for your business decision, not just the equipment itself.

Highly recommend! Spencer quickly came out and diagnosed my problem and even went the extra step to look into warranty after the company that put the unit in would not look into anything for me. Very knowledgeable and fairly priced. I’ll contact them from here on out for all my AC needs!

SIMS Heating and air installed a new unit for me last year. My A/C unit had quit and the well known carrier that i had bought the Carrier unit from wouldn’t even return my call, after being a customer for over 12 years. SIMS came through with excellent service and a great new unit.
- Robertson
My elderly mother’s 20 plus year old A/C unit decided to stop cooling. After calling some of the other A/C business, she was told there would be over a week wait. She gave SIMS a call and they had someone out that evening squeezing her in. Fantastic service and great people!
- HL Smith
If moving into a new home is not stressful enough, a finicky A/C unit added to the anxiety. Fortunately, Sims came to the rescue. Instead of the giving me the usual grunts and groans and quotes for a new unit, I got quick, efficient service that solved the problem right away.

Great experience. Fast reliable service. A/C system went down and the next day they were here to replace my system. Great pricing too. I have used them for A/C maintenance as well. Knowledgeable and friendly staff and on time. Lucky to find them.

Commercial HVAC Questions
What size rooftop units do you service?
We handle rooftop units 25 tons and under, covering most offices, retail spaces, and small commercial buildings across our coverage area.
Do you offer maintenance contracts for businesses?
Yes. Commercial maintenance contracts include scheduled inspections and priority response when something comes up, so you’re not choosing between routine care and staying open.
Can you service multiple units for a property management company?
Yes, we work with property managers handling HVAC across apartment complexes and multi-tenant buildings, with consistent service across every unit.
Do you offer same-day commercial service?
Often, yes, depending on the issue and our schedule. We understand that commercial downtime carries real cost beyond just discomfort.
How is commercial pricing different from residential?
It depends on the equipment and scope of the job. We inspect first and give you a written price before any work begins, same as residential, with no guesswork built in.
If you have questions, check our FAQs or give us a call. We’re here to help.
