We believe in transparency and education. Here are the most common questions we hear from our Seminole County neighbors.
How much does AC repair cost in Seminole County?
AC repair across Seminole County typically costs between $250 and $800 for common issues like capacitor replacement, refrigerant leaks, or fan motor failures. At Smart Home Air and Heat, we provide a transparent quote before any work begins, and our diagnostic fee is waived with completed repairs.
Do you serve all of Seminole County, including unincorporated areas?
Yes. We serve all 309 square miles of Seminole County — every incorporated city (Sanford, Altamonte Springs, Oviedo, Winter Springs, Casselberry, Lake Mary, Longwood) and every unincorporated community (Fern Park, Forest City, Wekiva Springs, Chuluota, Geneva, Heathrow). Our 90-minute guarantee covers them all.
My 1970s Seminole County home still has R-22 refrigerant. What should I do?
R-22 (Freon) was phased out of production in 2020. If your pre-2010 system still uses R-22, the remaining supply is extremely expensive — often $100–$200+ per pound. We recommend replacing the entire system with a modern R-410A or R-454B unit. The energy savings alone often justify the upgrade, especially with Seminole County's 8–10 month cooling season.
Why is humidity such a big problem in Seminole County?
Seminole County is surrounded by massive water systems — Lake Monroe, Lake Jesup (one of the largest in Central Florida), the St. Johns River, and the Wekiva River. These bodies of water create persistently high humidity that forces your AC to work overtime on dehumidification. Attic temps hit 140–160°F county-wide, compounding the problem.
How quickly can you get to my Seminole County home?
We guarantee a technician at your door within 90 minutes of your call, or you receive $200 off. This covers all of Seminole County — from Sanford in the north to Casselberry in the south, Chuluota in the east to Forest City in the west. Available 24/7 including nights and holidays.
Do Seminole County permits differ from Orange County for HVAC work?
Yes. Seminole County has its own building department with different permit requirements, inspection schedules, and fee structures than Orange County. We handle all Seminole County HVAC permitting for you — from application to final inspection — at no additional charge.
Should I prepare my Seminole County AC for hurricane season?
Absolutely. Hurricane-force winds can send debris into your outdoor condenser, and power surges during storms can damage your system's electronics. We recommend a surge protector on your HVAC system, trimming vegetation around your condenser, and having a post-storm inspection plan. Our maintenance plans include hurricane-readiness checks.
Do you offer financing for new AC installations in Seminole County?
Yes. We offer flexible financing for homeowners across all of Seminole County. We work with multiple lenders for low monthly payments and promotional 0% APR periods. A new system typically costs $5,500 to $15,000+ depending on home size and system type.
