AfterFast, Reliable AC Repair Across Longwood
AC repair in Longwood typically runs $150 – $650 and most calls are handled same day. We’re the AC Repair team that shows up when we say we will, with a written price before any work starts.
Brandt HVAC has been part of the Threshold Group family since 2003, and our crews know Longwood’s neighborhoods well. We dispatch from our Miami office, but our technicians live and work in Seminole County, which means we understand the specific headaches that come with cooling homes built during Longwood’s 1970s and 1980s building boom. Whether you’re in Sabal Point off SR 434, near the historic downtown district, or up in the Wekiva River basin, we’ll get a background-checked, uniformed technician to your door with a photo ID badge and a written estimate in hand. Call (984) 538-9003 anytime – a live person answers, 24 hours a day.
Why Brandt HVAC Is Longwood’s Preferred AC Repair Company
Longwood homeowners choose us because we solve the real problem, not just the obvious one. In subdivisions like Sabal Point and along the US 17-92 corridor, we’ve learned that a broken capacitor or low refrigerant is often a symptom of ductwork that’s been leaking for decades. Our 365-Day Done Right Promise means if a repair fails, we come back free of charge – no argument, no additional fee.
Every technician is Threshold Verified: background-checked, identity-confirmed, and introduced to you by name and photo before arrival. If someone shows up at your door who you weren’t told to expect, that visit is on us. For parents home with young children, older homeowners living alone, or anyone who wants to know exactly who’s walking through their door, this matters. We don’t think it should cost extra to feel safe in your own home.
Our phones are staffed by live people around the clock – nights, weekends, holidays. No voicemail trees, no callback queues. When your AC quits in a Longwood July afternoon with the attic pushing 140°F, you need a human who can dispatch help now, not tomorrow morning.
Emergency AC Repair in Longwood
Emergency AC Repair in Longwood means your system has failed when you need it most – typically May through October, when sustained heat and humidity make an unconditioned home uncomfortable within hours and dangerous for vulnerable residents overnight. We treat these calls as urgent. A live person answers your call, confirms your address in Longwood, and dispatches the nearest available technician with a written price in hand before any work begins. Most emergency repairs fall within our standard $150 – $650 range, though after-hours calls may carry a modest trip charge that we’ll quote upfront.
When to Call for Emergency Service
Call immediately if your system stops blowing entirely, you smell burning or electrical odors, or you hear loud grinding from the outdoor unit. In Longwood’s climate, indoor temperatures can climb past 85°F within two hours of system failure, and humidity spikes fast near the Wekiva basin. Don’t wait for “normal business hours” – we don’t have them.
What Our Technician Does on an Emergency Call
We diagnose first, explain second, repair third. Your technician will check refrigerant pressures, test electrical components including the capacitor and contactor, inspect the condensate drain for clogs common in high-humidity Longwood homes, and measure temperature split across the evaporator coil. If we find failed flex-duct leaking 20 – 30% of your conditioned air into a 140°F attic – typical in Sabal Point-era homes – we’ll show you the test results and explain whether a duct seal or full replacement makes sense before we touch the equipment.
AC Not Blowing Cold Air in Longwood
AC Not Blowing Cold Air is the most common call we get from Longwood homeowners, and the cause is rarely just “low refrigerant.” In this city’s 1970s – 1990s subdivisions, we’ve learned to suspect three interconnected problems: a failed electrical component, restricted airflow from duct leakage, or a frozen evaporator coil caused by both. Our crew recently serviced a 1980s Sabal Point home on the SR 434 corridor where the original flex-duct was leaking badly at the plenum collar and the attic was hitting 140°F. We found a failed run capacitor on the Carrier condenser and a clogged condensate line from high Wekiva-basin humidity, tested duct leakage at 25%, sealed the collars with mastic, and cleared the drain – restoring proper airflow and cooling without a full system swap. That repair came in under $400.
Capacitor and Electrical Failures
Florida’s lightning season and voltage fluctuations stress capacitors hard. A weak or swollen run capacitor can’t start the compressor properly, so your fan spins but the air stays lukewarm. We test capacitance with a meter, replace with an exact-match part, and verify amp draw on the new component. Most capacitor replacements in Longwood run $150 – $300, parts and labor included.
Refrigerant Issues and Leak Detection
Low refrigerant means a leak somewhere – period. We don’t just “top off” your system. Our technicians pressure-test the lineset, check the evaporator coil for pinholes common in older Longwood installations, and use electronic leak detection if needed. A refrigerant recharge with repair typically falls in the $300 – $500 range, depending on your system’s refrigerant type and the leak location.
Trusted Brands We Service in Longwood
We repair all major residential HVAC brands, including Trane, Lennox, Goodman, and Rheem. Our technicians carry common capacitors, contactors, and refrigerant fittings for these systems on every truck, which means faster repairs for Longwood homeowners without waiting on parts from Orlando. Whether you have a 15-year-old Goodman in a Sabal Point ranch or a newer Lennox system near the historic district, we’ve worked on it before. If your equipment uses a discontinued refrigerant like R-22, we’ll explain your options honestly – repair, retrofit, or replacement – with a written price for each path.
Common AC Repair Problems We See in Longwood Homes
- Failed flex-duct joints in Sabal Point-era homes. Original fiberglass ductwork from the 1970s and 1980s separates at plenum collars and sagging runs, leaking 20 – 30% of conditioned air into attic spaces that exceed 140°F in summer. We seal with mastic or replace with modern insulated duct where needed.
- Clogged condensate lines from Wekiva-basin humidity. Longwood’s northern neighborhoods near the river floodplain experience higher ambient moisture than drier inland Seminole County communities like Lake Mary. Microbial growth inside air handlers and drain pans accelerates, backing up condensate into overflow switches and shutting down the system.
- Undersized electrical panels blocking modern upgrades. Many Longwood homes from this era have 100-amp service or breaker configurations that can’t support the higher-demand blower motors and heat pump components in today’s equipment. We identify this before quoting any replacement.
- Single-zone systems fighting unbalanced floor plans. Original construction rarely included zoning or return-air pathways between rooms. Upstairs bedrooms roast while downstairs stays comfortable, and homeowners blame the equipment when the real issue is duct design from 1982.

FAQs About AC Repair in Longwood
Because the equipment isn’t the only thing failing. In Sabal Point and similar neighborhoods, original flex-duct leaks 20 – 30% at the collar, attic temperatures exceed 140°F in July, and electrical panels often can’t support modern equipment. A like-for-like swap without duct sealing, load calculation, and panel inspection will disappoint you. We test everything and give you a written price for the real fix. Call (984) 538-9003 for a free estimate.
It could be the capacitor, but in Longwood we also check for duct leakage and condensate clogs caused by Wekiva-basin humidity. A failed capacitor produces lukewarm air and sometimes a humming outdoor unit. Restricted airflow from leaking ductwork or a frozen coil produces similar symptoms. We diagnose with meters and duct tests, not guesses. Most capacitor replacements run $150 – $300. Call (984) 538-9003 to schedule.
Higher ambient humidity near the river basin accelerates microbial growth in air handlers and clogs condensate lines faster than in drier inland areas. This means more frequent service calls and sometimes more extensive cleaning or component replacement. The repair itself doesn’t cost more – the conditions create more complex problems to solve. We still give you a written price before any work starts.
Yes, absolutely. Original systems in 1972 – 1992 Longwood homes were often oversized or poorly matched to leaky ductwork. A proper Manual J load calculation accounts for your home’s actual envelope performance, including that 20 – 30% duct leakage we commonly find. Without it, you’ll get another mismatched system. We include this assessment in every replacement quote. Call (984) 538-9003 to schedule.
Florida’s climate demands efficient equipment, but the highest SEER2 rating isn’t always the smartest buy for an older Longwood home with leaky ducts. We typically recommend systems in the 15 – 17 SEER2 range paired with duct sealing, which delivers better real-world efficiency than an 18+ SEER2 unit connected to 30% leaking ductwork. We’ll show you the math in writing before you decide.
