Fast, Reliable Furnace Repair Across Addison
Furnace repair in Addison typically costs $150 – $700 and is often completed same-day, though mid-rise rooftop and corridor access can add scheduling complexity you won’t find in suburban slab-on-grade homes. Our Furnace Repair team knows Addison’s housing stock inside out, from the locked utility closets of Addison Circle to the packed rooftop units above Belt Line Road’s restaurant corridor. We’re dispatched from our Dallas-Fort Worth office, with crews serving Addison locally and carrying the parts that break most often on the Carrier, Trane, and Goodman systems common here.
When your corridor thermostat drops below 60°F or your rooftop unit throws a pressure switch fault, you need someone who understands that Addison’s 20-25 year old packaged systems aren’t accessed through a garage door. Call (984) 538-9003 and a live person answers, 24 hours a day. We’ll send you a photo and name of your technician before they arrive, verified through our Threshold Verified standard, so you know exactly who is walking through your door or meeting the property manager at the roof access.
Why Brandt HVAC Is Addison’s Preferred Furnace Repair Company
We’ve been part of the Threshold Group family since 2003, and our Addison customers keep calling us back because we treat their buildings like the complex systems they are. Mid-rise HVAC isn’t suburban residential work with an elevator, it’s a different discipline entirely, and our technicians train specifically on the access, clearance, and coordination challenges that come with rooftop packaged units and corridor closet furnaces.
Our response time to Addison runs same-day for most calls received before 2 PM, and emergency no-heat calls get prioritized when temperatures drop below freezing. We know the difference between a true emergency and a scheduled repair, and we don’t inflate the urgency to inflate the bill.
Every repair starts with a written price before any work begins, no exceptions. That price includes parts, labor, and our 365-Day Done Right Promise, if the repair fails, we return at no charge. No argument, no additional fee. You’ll see the technician’s name, photo, and background-check verification before they arrive, and they’ll show a photo ID badge at the door. If anyone shows up who you weren’t told to expect, that visit is on us.
Furnace Maintenance in Addison
Furnace Maintenance in Addison is essential preventive care for heating systems that work harder than most homeowners realize, especially in mid-rise buildings where a single furnace failure can leave a dozen units cold. Our tune-up service costs $80 – $200 and includes a complete combustion analysis, heat exchanger inspection, blower motor amp draw test, and filter assessment. For Addison Circle properties and similar mid-rise communities, we also check corridor static pressure and rooftop condenser coil condition, because these systems are interconnected in ways suburban split systems aren’t.
What We Check on Mid-Rise Systems
Closet-hung furnaces in Addison’s apartment buildings collect dust differently than garage units, restricted airflow in utility corridors means blower compartments rarely get natural ventilation, and flame sensors foul faster. We pull and clean every flame sensor, check igniter resistance, and verify the induced draft motor is moving the correct CFM. On rooftop packaged units, we inspect heat exchanger cells with a borescope where access allows, and we document coil fin condition because Addison’s urban heat island drives near-continuous summer runtime that degrades equipment faster than seasonal use.
When to Schedule in Addison
We recommend Furnace Maintenance in early October, before the first cold snap sends every Addison property manager calling at once. Buildings with original 1999-2004 systems should consider a pre-winter inspection even if the heat worked fine last year, those heat exchangers are at the end of their designed service life, and a cracked exchanger leaking CO into corridor ductwork is a silent hazard no tenant can detect until it’s dangerous.
Heat Pump Repair in Addison
Heat Pump Repair in Addison addresses systems that provide both heating and cooling through a single refrigerant loop, common in Addison Circle’s original construction and in newer mini-split installations where ductwork cannot be run through existing mid-rise structure. Our heat pump repair service runs $150 – $650 and covers everything from refrigerant leak detection and recharge to reversing valve replacement and defrost board troubleshooting. Because Addison heat pumps work year-round, they accumulate runtime hours faster than systems in milder climates, and the February 2021 freeze proved how many were undersized for extended defrost cycles in single-digit temperatures.
Defrost and Reversing Valve Failures
The most common winter heat pump call we get in Addison is a unit stuck in cooling mode or icing up completely. Usually it’s a failed reversing valve solenoid or a defrost board that can’t terminate its cycle. We test every stage, verify outdoor coil temperature sensor accuracy, and check refrigerant charge by weight, not guesswork. A low charge in January often traces back to a leak that started in July’s 100°F stretch, thermal expansion and contraction finally opened it enough to matter.
Supplemental Heat Strip Issues
When Addison temperatures drop below 35°F, heat pumps call on electric heat strips as backup. After Storm Uri, we replaced dozens of burned-out heat strip sequencers and limit switches in Addison buildings where the strips ran continuously for days. We test amp draw on every heat strip element and verify the sequencer stages correctly, a failed sequencer running all elements at once will trip breakers and create a fire risk.
Trusted Brands We Service in Addison
We service all major residential HVAC brands in Addison, including Trane, Lennox, Goodman, and Rheem, and we stock the most common failure parts for these systems locally. For Addison’s mid-rise buildings, that means igniters and flame sensors for the Carrier and Bryant closet furnains common in 2000s construction, defrost boards for the heat pumps still running after two decades on Addison Circle rooftops, and blower motors that fit the restricted clearance of corridor utility closets. Fast turnaround matters when a single furnace serves multiple units, so we coordinate with property managers for roof-deck access and maintain relationships with local parts distributors who understand the urgency of a no-heat call in a fully occupied building.
Common Furnace Repair Problems We See in Addison Homes
- Heat exchanger cracks in 20+ year rooftop packaged units. Addison’s original Addison Circle systems hit designed end-of-life years ago, and the thermal stress of 100°F summer runtime followed by hard winter freezes opens cracks that leak carbon monoxide into corridor duct systems. We inspect with borescopes and combustion analyzers, and we don’t patch what needs replacement.
- Igniter and flame sensor failures in closet-hung furnaces. Restricted utility corridor access means these blower compartments rarely get cleaned, and dust accumulates until the flame sensor can no longer detect pilot presence. The furnace lights, then shuts down on safety, over and over, leaving tenants cold and confused.
- Frozen condensate lines in high-efficiency condensing furnaces. Addison Circle’s closet-installed 90%+ efficiency furnaces produce acidic condensate that exits through plastic lines, often routed through unheated corridor ceiling spaces. When a winter storm hits, the line freezes, the furnace faults out, and melting ice damages the apartment below.
- Defrost board failures on rooftop heat pumps after extended summer runtime. Addison’s urban heat island pushes rooftop units harder than suburban equivalents, and the control boards that manage winter defrost cycles degrade from thermal cycling. A stuck defrost means a heat pump that ices solid or never defrosts at all.
Pricing for Furnace Repair in Addison, TX
Most furnace repairs in Addison fall between $150 and $700, with the final cost depending on part type, access difficulty, and whether we’re working on a closet-hung residential unit or a rooftop packaged system requiring roof-deck coordination. An igniter replacement on a standard closet furnace typically lands at the lower end, a heat exchanger diagnosis with borescope inspection and combustion verification runs higher, and control board replacements with full system testing fall in the middle.

What affects your specific price: the age and brand of your system, whether parts are still manufactured for 1999-2004 equipment, roof-deck or locked-corridor access requirements, and whether we find secondary issues during diagnosis. We give you a written price before any work starts, every time, with no exceptions. Estimates are free, and we don’t charge overtime for after-hours calls to occupied buildings with no heat. Call (984) 538-9003 for your exact quote.
We Also Serve Cities Near Addison
Our Addison crews also handle furnace repair calls in Carrollton, Richardson, Coppell, and Plano, though the housing stock and access logistics differ significantly. Carrollton and Plano’s slab-on-grade tract homes present simpler access but different equipment ages and brands, Richardson’s split between mid-rise and single-family requires adaptability, and Coppell’s newer construction means fewer mass-replacement-cycle emergencies but more complex zoning and smart-home integration issues. We dispatch from the same Dallas-Fort Worth office and apply the same Threshold Verified standard to every call.

FAQs About Furnace Repair in Addison
Yes, we repair locked-corridor and locked-closet furnaces regularly in Addison Circle and similar properties. We coordinate with your property manager or HOA for access, and our technicians carry the tools to work in restricted clearances where standard residential furnace pull-and-replace methods don’t fit. Call (984) 538-9003 and we’ll arrange access with your building management, estimates are free.
It could be either, and the specific trip pattern tells us which. A heat exchanger crack causing rollout will trip the high-limit switch, not the breaker, while a failing blower motor or seized inducer draws excess amps and trips the breaker directly. We test both scenarios with an amp meter and combustion analyzer before recommending repair or replacement, because at 23-24 years old, this system is at designed end-of-life regardless. Call (984) 538-9003 for a diagnostic, we’ll give you a written price before any work starts.
Short-cycling in commercial corridor systems usually means overheating due to restricted airflow, a failing flame sensor that drops out mid-cycle, or an oversized furnace hitting high-limit too quickly. In Addison’s restaurant corridor buildings, we also see makeup air imbalance causing pressure issues that affect furnace operation, especially when kitchen exhaust runs without adequate replacement air. We diagnose the root cause, not just the symptom, and we understand the commercial HVAC interactions that residential-only contractors miss. Call (984) 538-9003 for same-day service.
Most repairs do not require permits in Addison, but heat exchanger replacement on a rooftop packaged unit sometimes triggers inspection requirements depending on gas line modification scope. We handle permit research and filing when needed, and we know Addison’s building department expectations from years of working with local property managers on mid-rise HVAC projects. We’ll tell you upfront if your specific repair requires permitting, no surprises after work begins.
We prioritize no-heat calls to occupied buildings, especially those with vulnerable residents, and we stage common failure parts locally before storms hit based on forecast. During Storm Uri, we learned that Addison’s corridor closet furnaces failed in predictable patterns: frozen condensate lines, failed heat strips on heat pumps, and ignition lockouts from low gas pressure. We now carry more condensate line heat tape, heat strip sequencers, and intermittent pilot assemblies than standard inventory, and our 24/7 live answering means you reach a person, not a callback queue, when it’s 12°F outside. Call (984) 538-9003 anytime, we’re staffed around the clock.
Brandt comes from an old word for firebrand, a fitting name for the work of keeping Addison homes warm. When your furnace fails in a locked corridor closet or on a windswept rooftop above Belt Line Road, you need technicians who understand this city’s unique building stock and access challenges, not suburban HVAC contractors learning mid-rise logistics on your dime. We verify every identity, quote every price in writing, and guarantee every repair for 365 days. That’s the Threshold Verified standard, and it’s how we’ve worked since 2003.
