We serve the master-planned communities that make Lake Mary what it is: Heathrow, Magnolia Plantation, Timacuan, and the neighborhoods along Lake Mary Boulevard and Rinehart Road.

Why Halden Heating and Air Orlando Is Lake Mary’s Preferred Furnace Repair Company
Lake Mary homeowners deal with a specific set of furnace problems that a generic Orlando contractor often misses. The original 1990s Trane and Carrier systems still running in Heathrow and Magnolia Plantation were sized for a different era, and they’re now paired with multi-zone layouts, high ceilings, and humidity demands those old units were never designed to handle. We’ve worked on enough of them to know the failure patterns cold. When a furnace in a two-story executive home short-cycles or one floor goes cold while the other stays warm, we check the zone dampers and board first, because that’s what fails here.
Every tech we send into Lake Mary is background-checked, uniformed, and dispatched with a live arrival time you can track to your door. No four-hour windows. Our written price lands before any tool comes off the truck, and every repair carries a written guarantee with a free return visit if the same problem comes back. That’s our 365-Day Done Right Promise, and it applies in Lake Mary just like everywhere else we work. Andre Fuller, who leads our team, built the company on a simple rule: if the repair isn’t done right, we make it right, on our dime and our time.
We’re independently owned and operated under the Relay Home Co. network, held to The Relay Visibility Guarantee on every job. That means the price you approve is the price you pay, and the work we quote is the work we do. Founded in 2004, we’ve spent two decades learning what actually breaks in Central Florida furnaces, not just what the manual says should break.
Styles & brands we work with
Furnace Tune Up in Lake Mary
A Furnace Tune Up in Lake Mary runs $80 to $200 and should happen every fall before the first real cold snap hits. Most Lake Mary furnaces sit dormant from March through November, which gives capacitors time to degrade, ignitor connections time to corrode, and dust time to pack into blower wheels. A tune-up catches those issues before the furnace gets called back to work. Given the lightning density in this part of Seminole County, checking capacitor condition and contactor contacts is the single most valuable thing we do during a Lake Mary tune-up.
What We Inspect
We test the heat exchanger for cracks, check gas pressure at the valve, measure ignitor resistance, and inspect capacitor microfarad readings against manufacturer spec. We also clean the flame sensor and condensate lines. The report you receive shows actual measurements, not just checkmarks.
Humidity and Airflow Checks
Lake Mary’s subtropical humidity makes static pressure checks critical on multi-zone systems. A dirty blower wheel or closed damper that goes unnoticed in a dry climate creates real moisture problems here. We verify airflow across both zones and flag any static pressure reading above the manufacturer’s range.
Emergency Furnace Repair in Lake Mary
Emergency Furnace Repair in Lake Mary is available around the clock, and most emergency calls run between $150 and $700 depending on the part that failed. A real person answers our phone at 3 a.m., not a voicemail tree. If your furnace dies on the coldest night of February, we dispatch a technician to Lake Mary from our South Florida metro office without wasting time on phone tag.
After-Hours Dispatch
Our emergency line is staffed 24/7, which matters in Lake Mary because cold snaps here are rare but sharp. When the temperature drops into the 30s, a furnace that’s been idle for nine months often fails on startup. We respond fast, with the parts truck stocked for the brands we see most in Lake Mary: Carrier, Trane, Goodman, and Lennox.
What Counts as an Emergency
A furnace that won’t light, a burning smell, a carbon monoxide detector going off, or no heat in a home with infants or elderly residents all justify an emergency call. If you smell gas, get out and call your utility first, then call us. We’ll walk you through what to check over the phone while a tech heads your way.
Trusted Brands We Service in Lake Mary
We’re certified to service Carrier, Trane, Lennox, and Goodman furnaces, which covers the vast majority of systems in Lake Mary. The 1990s Trane units in Heathrow and the early-2000s Carrier systems in Magnolia Plantation are brands our techs see weekly. We keep common replacement parts stocked for these models, which means less waiting for parts that Orlando supply houses don’t always carry. When a gas valve or ignitor fails in Lake Mary, we’re typically able to complete the repair the same day rather than scheduling a second visit.
Common Furnace Repair Problems We See in Lake Mary Homes
- Lightning-struck capacitors and contactors. Lake Mary’s afternoon thunderstorms are frequent and intense, and the resulting power surges kill capacitors and contactors faster than anything else we see. Heathrow and Magnolia Plantation systems take the worst of it because the neighborhoods sit in open, flat terrain with tall two-story homes that attract strikes.
- Multi-zone damper failures. Two-story executive homes in Lake Mary use motorized dampers to split heat between floors, and those damper motors wear out. When one floor stays cold while the other bakes, the damper usually stopped responding to the zone board.
- Short-cycling from undersized 1990s furnaces. Original furnaces from the 1990s were sized for smaller heat loads, and they now cycle on and off too frequently in 2,500 to 4,500+ square foot homes. Short-cycling accelerates wear on ignitors and heat exchangers and leaves humidity swings across zones.
- Ignitor and flame sensor corrosion. Lake Mary’s humidity accelerates corrosion on ceramic ignitors and flame sensors, especially in furnaces that sit idle for nine months of the year. A corroded flame sensor causes a furnace to light and then shut off within seconds.

AfterPricing for Furnace Repair in Lake Mary, FL
Furnace repair in Lake Mary runs $150 to $700, with the final number driven by the part that failed and the complexity of your system. A capacitor replacement on a single-stage furnace lands at the lower end of that range. A gas valve replacement or blower motor replacement on a multi-zone executive home lands higher, especially if we’re also recalibrating zone dampers. We put the price in writing before work begins, every time. You’ll never see a number added at the door.

FAQs About Furnace Repair in Lake Mary
Lake Mary’s flat, open terrain and tall two-story homes make Heathrow and Magnolia Plantation unusually vulnerable to lightning-induced power surges, and those surges kill capacitors and contactors. The original 1990s Trane and Carrier units in these neighborhoods were never equipped with the surge protection that modern systems include. After a storm, we see a spike in no-heat calls where a capacitor is out of spec or a contactor is welded shut. A whole-home surge protector plus a capacitor check during your fall tune-up can prevent most of these failures. Call (850) 695-3178 for an exact quote.
Balancing a two-story Lake Mary home requires checking zone damper operation, static pressure readings, and thermostat calibration on both floors. When one floor stays cold, the cause is usually a failed damper motor or a zone board that’s no longer sending the open signal. We test the dampers manually, verify the zone board is functioning, and adjust the blower speed to match what the ductwork can actually handle. For 2,500 to 4,500+ square foot executive homes with high ceilings, we may also recommend balancing dampers or a variable-speed blower if the existing furnace is oversized or undersized for the zone load.
Most furnace repairs in Lake Mary fall between $150 and $700, with capacitor and contactor replacements on the lower end and gas valve or blower motor replacements on the higher end. Multi-zone systems often cost more because we verify damper operation and airflow balance after the repair, not because of inflated parts pricing. Every repair includes a written price before work starts and a written guarantee. Call (850) 695-3178 for a free estimate on your specific system.
A tune-up can’t prevent a direct lightning strike, but it can identify a capacitor or contactor that’s already weakened by past surges and due to fail on the next cold night. During our $80 to $200 Furnace Tune Up, we measure capacitor microfarads and inspect contactor contacts for pitting or welding. We also recommend whole-home surge protection for Lake Mary homes in Heathrow and Magnolia Plantation, where the thunderstorm exposure is highest. Replacing a weakened component during a tune-up costs less than an emergency dispatch at midnight.
Short-cycling in Lake Mary almost always comes down to an oversized furnace, a clogged filter, or a failing zone damper causing the high-limit switch to trip. The original 1990s furnaces in many Lake Mary homes were matched to smaller loads, and as heat demand has shifted, those units cycle on and off rapidly. That rapid cycling accelerates wear on ignitors, heat exchangers, and blower motors. We diagnose short-cycling by reading the error codes, testing the limit switch, and verifying airflow across both zones before recommending a repair or replacement. Call (850) 695-3178 and we’ll walk you through what you’re seeing.
