What Deltona Homeowners Should Know
Volusia County's Largest City
Deltona is the largest city in Volusia County by population, which means a wide range of housing ages and system types across its many subdivisions.
County-Wide Growth
Volusia County has grown to more than 606,000 residents, up roughly 9.6 percent since 2020, with Deltona representing a significant share of that growth along the I-4 corridor.
Lake-Dotted Subdivisions
The Deltona Lakes network of subdivisions sits near numerous small lakes, and homes closer to water often deal with more humidity than those further inland.
Heat Pump Country
Like most of Volusia County, Deltona relies on heat pumps rather than gas furnaces for the large majority of homes.
Deltona Areas & Landmarks We Serve
Deltona Lakes
The extensive network of lake-dotted subdivisions that make up much of residential Deltona, each with its own humidity considerations.
Howland Boulevard Corridor
A major commercial and residential corridor running through the city, and a route our technicians know well.
I-4 Corridor
The growth corridor along the interstate, where newer construction is concentrated, and new installations are common.
Osteen Area
The rural community at the edge of Deltona, part of our core coverage with the same rates as the rest of the city.

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!
- Ashton Cassidy
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.
