Call (817) 402-2972

We’ve worked the Addison market long enough to know the local housing stock inside and out. This town isn’t like Carrollton or Richardson. The residential buildings here are overwhelmingly multi-family, built from the mid-1970s through the 1990s when Addison exploded as a commercial hub. That means shallow second-floor furnace closets, rooftop package units, and combustion-air problems that a technician trained on standard suburban single-family homes simply won’t recognize. Our Furnace Repair team knows how to work in tight Addison spaces, and we carry parts for the Trane, Lennox, Goodman, and Rheem systems we see most often in these complexes. Call us at (817) 402-2972 when you need heat restored.

Why Coldharbour Heating & Air Is Addison’s Preferred Furnace Repair Company

Addison property managers and homeowners call us back because we show up when we say we will and we put our guarantee in writing. The Kingswell Way, which every Coldharbour technician follows, means four things: we say the price before the work starts, we arrive in the window given, we leave the job site cleaner than we found it, and we hand you a written 365-Day Done Right Promise before we leave. If that repair fails inside a full year, we come back and correct it at no charge. No argument, no additional invoice.

Our phones are answered by a live person around the clock, every day of the year. No voicemail trees, no “call back in the morning” when your heat quits at midnight in an Addison Circle condo. Dispatch and scheduling are coordinated from our Dallas-Fort Worth office, and crews serve Addison locally with parts stocked for the brands we see most in this market.

Every technician is background-checked and uniformed, trained to service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in Addison, where a single failed ignition control in a shared rooftop unit can take heat from an entire stack of condos at once. You need someone who can diagnose fast and repair on the spot, not call for a second visit because they didn’t stock the right igniter.

Heating Repair in Addison

Heating Repair in Addison means working on systems that rarely fit the suburban playbook. Most of the town’s residential heat comes from package units mounted on rooftops or sidewalls, or from forced-air furnaces crammed into shallow second-floor closets with barely enough room to open the access panel. These installations, common in the condo and apartment complexes built along Belt Line Road and near Addison Circle, create repair challenges you won’t find in Carrollton’s single-family garages or Plano’s basement utility rooms.

When we get a heating repair call in Addison, the first thing we check is access and combustion air. A furnace starving for return airflow because the closet is too shallow will short-cycle, overheat, and burn out components faster than the manufacturer ever intended. Our diagnostic fee covers a full inspection of the heat exchanger, burner assembly, ignition system, and blower motor, plus static pressure testing to confirm whether the installation itself is forcing the equipment to work too hard. Most heating repairs in Addison fall in the $150-$700 range, with the final cost depending on which components have failed and whether the root cause is a bad part or a bad installation that needs correcting.

Closet Access and Clearance Issues

Shallow utility closets in 1970s and 1980s Addison complexes often lack the minimum combustion-air openings the current code requires. We measure clearances, check louvers, and document whether restricted airflow contributed to the failure. Sometimes the repair is straightforward, a cracked igniter or failed capacitor. Other times we need to recommend modifications to prevent the same failure next winter.

Rooftop Package Unit Diagnosis

Many Addison condos heat through a shared rooftop unit serving multiple floors. When one of these fails, the cause is often grease-laden intake air drawn from the dense restaurant exhaust along Belt Line Road. We inspect heat exchangers for coking, flame sensors for fouling, and burners for carbon buildup that standard suburban units simply don’t experience.

Boiler Repair in Addison

Boiler Repair in Addison is less common than forced-air work, but the town’s older multi-family buildings and some commercial-to-residential conversions still rely on hydronic heat. These systems, often original to 1970s construction or added during 1990s renovations, run into problems that mirror the access and ventilation constraints of their furnace counterparts. Boiler closets are tight, venting runs are long, and the combination of Addison’s hard water and irregular maintenance produces scaling and circulation failures we don’t see as often in newer suburbs.

Our technicians are trained to diagnose boiler issues across the major brands, including cast-iron and high-efficiency condensing models. A typical boiler repair in Addison costs $150-$700, depending on whether the problem is a failed circulator pump, a stuck zone valve, a cracked heat exchanger, or mineral buildup restricting flow through the boiler and piping. We pressure-test the system, check expansion tank charge, and verify that the relief valve operates at its rated setpoint before we call the job complete.

Circulator and Zone Valve Failures

Addison’s older apartment complexes often run original circulator pumps past their design life. A pump that seizes or runs but doesn’t move water leaves residents with cold radiators or baseboards on one or more floors. We test amp draw, check for air-locked zones, and replace the pump or valve with a correctly sized unit.

Scale and Water Quality Damage

North Texas water hardness builds mineral deposits in boiler heat exchangers over years of operation. We descale where possible and recommend water treatment when the damage is recurring. In Addison’s 1970s buildings, we’ve found boilers running at half their rated output because scale has reduced heat transfer to the point where the thermostat never satisfies.

Trusted Brands We Service in Addison

We stock common repair parts for Trane, Lennox, Goodman, and Rheem systems because these are the brands we encounter most often in Addison’s 1970s-through-1990s multi-family housing stock. Trane and Lennox package units dominate the rooftop installations serving condo complexes near Addison Circle and along Midway Road. Goodman and Rheem furnaces appear frequently in the town’s older apartment renovations, where builders chose reliable, serviceable equipment that could be maintained without specialized tools. Our technicians carry igniters, flame sensors, blower motors, capacitors, and gas valves for these brands on every truck, which means most Addison repairs are completed in a single visit without waiting for a parts run. If your system is a Carrier, York, Bryant, American Standard, or Daikin, we service those too, with parts available through our Dallas-Fort Worth supply network on a next-day basis if not stocked locally.

Common Furnace Repair Problems We See in Addison Homes

• Grease-fouled flame sensors and burners: Rooftop package units serving Addison condos pull intake air from an environment saturated with kitchen exhaust from over 180 restaurants along Belt Line Road. Flame sensors coated in grease film can’t detect burner ignition, causing lockout cycles that leave residents cold. We clean or replace the sensor and inspect the burner assembly for coking that standard maintenance schedules miss.
• Blower motor burnout from high static pressure: Shallow second-floor closets in 1970s and 1980s complexes restrict return airflow. The blower works harder, draws more amps, and eventually fails. We measure static pressure, replace the motor with the correct horsepower rating, and advise on filter changes because the tight clearance makes homeowner maintenance difficult.
• Cracked heat exchangers from short-cycling: When a furnace oversized for the ductwork or starved for combustion air heats up too fast, it cycles on and off repeatedly. The heat exchanger expands and contracts until it cracks, creating a carbon monoxide risk. We test with a combustion analyzer and replace the exchanger or recommend system correction.
• Failed igniters in shared rooftop units: One ignition control board or hot-surface igniter failure in a multi-unit rooftop package unit takes heat from every condo in the stack. These calls spike on the first cold snap of the season when equipment that sat idle through Addison’s brutal summer finally fires after months of disuse.
