Brandt HVAC dispatches technicians to Lake Mary from our Miami scheduling office, with crews working Seminole County daily.

Why Brandt HVAC Is Lake Mary’s Preferred Furnace Repair Company
We’ve built our reputation in Lake Mary on one thing that matters to homeowners here: certainty about who is walking through your door. Our Furnace Repair team follows the Threshold Verified standard. Every technician is background-checked and identity-verified. We send you their name, photo, and badge number before arrival. If anyone shows up who you weren’t told to expect, that visit is on us.
Lake Mary homeowners choose us because we understand their homes. The multi-zone systems in communities off International Parkway. The HOA compliance layers that out-of-area contractors miss. The salt corrosion that affects outdoor equipment more aggressively here than even neighboring Sanford or Longwood.
Our phones are answered by a live person, never an automated tree, every hour of every day. That matters when your furnace fails on a January night and the temperature is dropping toward 40 degrees.
Devin Marlowe leads Brandt HVAC with a straightforward approach: name the problem, give the price in writing, fix it right, and stand behind it for 365 days. No exceptions.
Emergency Furnace Repair in Lake Mary
Emergency Furnace Repair in Lake Mary means responding to calls where the heat is out completely, the system is making dangerous noises, or there’s a suspected gas leak or carbon monoxide risk. We treat these calls with urgency. A failed furnace in Lake Mary isn’t merely uncomfortable; January nights can drop into the 30s, and homes here with high ceilings and open floor plans lose heat fast. Most emergency repairs fall within our standard $150 – $700 range, with no overtime charge for nights, weekends, or holidays.
What Counts as a Heating Emergency
No heat at all, especially with young children, older residents, or anyone with health conditions in the home. The smell of gas near the furnace. A carbon monoxide detector alarm. Screeching or grinding sounds that suggest motor bearing failure. If you’re unsure, call (984) 538-9003. Our dispatcher will walk you through immediate safety steps and get a technician moving.
Our Emergency Response Process
When you call, we confirm your Lake Mary address and the symptoms you’re seeing. We send your technician’s photo and ID before they arrive. They diagnose the system, present a written price, and begin repair only after you approve it. Most emergency calls are resolved same-day.
Furnace Maintenance in Lake Mary
Furnace Maintenance in Lake Mary is preventive care designed for this specific environment. Our tune-up service runs $80 – $200 and includes a complete inspection, cleaning, and calibration of your heating system. Given Lake Mary’s intense humidity and salt-laden air, we pay particular attention to corrosion on outdoor condenser cabinets and coil fins, static pressure across multi-zone ductwork, and electrical component integrity after thunderstorm season.
What’s Included in Our Tune-Up
We inspect the heat exchanger for cracks, test gas pressure and burner operation, measure temperature rise, check blower motor amp draw, and examine the capacitor and control board for heat or surge damage. We clean the flame sensor, check the condensate drain, and verify thermostat calibration. You receive a written report of everything we found, with photos if we spot concerns.
Why Lake Mary Homes Need Twice-Annual Attention
The combination of coastal salt air, high indoor humidity, and afternoon voltage spikes creates a wear pattern we see repeatedly in Lake Mary. Systems here age faster than the manufacturer predicts. A furnace that might last 20 years in drier inland climates often shows heat exchanger stress and blower motor strain by year 15. Maintenance catches these patterns before they become emergency failures.
Trusted Brands We Service in Lake Mary
We repair all major residential furnace brands in Lake Mary, including Goodman, Rheem, and York units that remain common in the 1985 – 2005 build-out. Our technicians carry common failure parts for these systems, which means faster repairs without waiting on warehouse orders. We also service Carrier, Trane, Lennox, Daikin, Bryant, and American Standard equipment. For Lake Mary homeowners in HOA communities like Heathrow, we maintain equipment data sheets and specification documentation that architectural review boards require for any replacement project. That preparation saves weeks on jobs where out-of-area contractors get stalled.
Common Furnace Repair Problems We See in Lake Mary Homes
- Corroded outdoor condenser coils and cabinets. Salt-laden air from the coast accelerates corrosion on outdoor equipment years faster than in inland Seminole County. We see pitted coil fins and refrigerant leaks on systems that should have years of life left, especially on homes near International Parkway and Rinehart Road.
- Heat exchanger cracks on aging R-22 systems. Lake Mary’s oversized multi-zone systems create static pressure imbalances that strain blower motors and heat exchangers. The 20-to-35-year-old Goodman and Rheem units common here develop stress cracks that can leak carbon monoxide. We inspect every heat exchanger with a camera on every service call.
- Capacitor and control board failure after thunderstorms. Afternoon voltage spikes across Lake Mary HOA neighborhoods frequently burn out multiple capacitors and control boards the same afternoon. We stock these components and can often restore heat the same evening.
- Blower motor failure from humidity strain. Lake Mary’s sustained high indoor relative humidity forces blower motors to work harder to move air through moisture-laden ductwork. We measure static pressure and recommend duct sealing or dehumidification upgrades when we find this pattern.
Pricing for Furnace Repair in Lake Mary, FL

FAQs About Furnace Repair in Lake Mary
Salt-laden air accelerates corrosion on outdoor condenser cabinets and coil fins, causing refrigerant leaks and premature component failure years earlier than in inland Seminole County. We recommend corrosion-resistant coil options and more frequent cleaning intervals for Lake Mary homes, particularly those near International Parkway and Rinehart Road. Call (984) 538-9003 for an inspection and exact recommendation.
Yes. Heathrow’s architectural review board requires pre-approval of placement, screening enclosures, and equipment specifications before any outdoor condenser swap can proceed. We carry equipment data sheets and color-match documentation for this exact purpose. Out-of-area contractors often get caught off guard by this step, which routinely adds one to three weeks to the timeline. We handle the paperwork as part of our standard replacement process.
Intense afternoon thunderstorm activity produces voltage spikes that burn out capacitors and control boards across entire Lake Mary neighborhoods on the same afternoon. We see clusters of calls from the same HOA communities within hours of a storm. Surge protectors help, but the most reliable protection is annual maintenance that catches weakened components before the next storm season. Call (984) 538-9003 to schedule.
At 20 years, most R-22 systems in Lake Mary are at or past their reliable service life, especially given the humidity and salt exposure here. If the repair is under $300 and the heat exchanger shows no cracks, repair can buy you a season or two. If the heat exchanger is cracked, the blower motor is failing, or you’re facing a refrigerant leak on the outdoor side, replacement is usually the smarter investment. We give you both numbers in writing so you can decide. Estimates are free.
We recommend twice-annual maintenance for Lake Mary homes: once before heating season and once before cooling season. The salt air, high humidity, and electrical surge risk here create a faster wear cycle than the manufacturer standard assumes. Our $80 – $200 tune-up includes a written report of everything we find, with no pressure to buy additional services. Call (984) 538-9003 to schedule your first visit.
