HVAC Services in Seminole County
Local HVAC Service from the Team That’s Been Here Since 1983
Del-Air Heating, Air Conditioning & Refrigeration, LLC was founded in Sanford, the Seminole County seat, and has been headquartered there since day one. That’s more than four decades of serving the same community our company grew up in, backed by multiple locations across Florida and a fleet of over 400 service trucks. When you call us, you’re reaching an HVAC contractor with real roots in Seminole County and the scale to respond fast.

Why Seminole County Homeowners Call Del-Air Heating, Air Conditioning & Refrigeration, LLC
Speed matters when your AC goes out in July. We offer same-day service for urgent issues and emergency support around the clock, so you’re not stuck waiting. Our technicians arrive in fully stocked vehicles equipped to handle most repairs on the spot, which means fewer return trips and faster resolution.
Every technician on our team is licensed, bonded, and insured and background-checked before entering your home. They receive ongoing training and work with updated tools and technology. We also provide service in Spanish for customers who prefer it.
We work on all brands and models. Whether your system was installed last year or over a decade ago, you won’t hear us say we can’t touch it because it’s not our brand.
A Full-System Approach to Home Comfort
Most HVAC problems don’t exist in isolation. We take a full-system view when diagnosing issues, looking for root causes rather than applying a quick fix that leaves the underlying problem in place. That approach takes a little more time up front and can save considerably more time and money over the long run.
We also handle plumbing and electrical work, so one call can address problems across multiple home systems. Our team is guided by a straightforward set of values: show up on time, communicate honestly, and do work worth being proud of.
