Styles & brands we work with
Furnace Maintenance
Furnace Maintenance means a thorough, scheduled inspection and tune-up of your heating system to catch small problems before they become breakdowns. In Dallas, where furnaces sit idle for eight months of the year, dust buildup and component wear happen quietly. When problems do surface, our Furnace Repair in Dallas gets you warm again fast. Brandt HVAC Co Dallas recommends a maintenance visit every fall, before the first real cold snap hits, and most Furnace Maintenance visits in Dallas run $80 to $200. Our technicians check gas pressure, heat exchanger integrity, ignition performance, airflow, and carbon monoxide safety on every visit, and you get a written report of what we found and what it costs to fix anything that needs attention.
Seasonal Startup Inspection
Dust, pet hair, and debris settle inside your furnace during the long Texas cooling season. Starting the furnace without cleaning the burners and checking the heat exchanger can shorten its life and increase your gas bill. We clean what needs cleaning, test what needs testing, and tell you honestly whether your furnace is ready for winter.
Filter and Airflow Check
A clogged filter makes your furnace work harder and can cause overheating that trips the safety limit switch, leaving you without heat on a cold night. During a Furnace Maintenance visit, we measure airflow and replace or recommend the right filter for your system. This one step extends equipment life more than almost anything else.
Heat Pump Repair
Heat Pump Repair covers fixes to the outdoor condenser unit, indoor air handler, and the refrigerant lines that connect them when your heat pump stops producing warm air. Many Dallas homes rely on heat pumps for both heating and cooling, and when the reversing valve fails or refrigerant runs low in heating mode, the house stays cold even though the system runs constantly. Heat Pump Repair in Dallas typically ranges from $150 to $700 depending on the failing component. Brandt HVAC Co Dallas technicians diagnose the exact cause, explain it in plain English, and hand you a written price before touching a single part.
Reversing Valve Service
The reversing valve is what tells a heat pump whether to heat or cool, and when it sticks or fails, your system may blow cold air when you’re asking for heat. This is a common repair on older Trane and Lennox heat pumps around Dallas. We test the valve, confirm the diagnosis with voltage and pressure readings, and quote the repair before we start.
Refrigerant Recharge and Leak Repair
Refrigerant recharge means refilling the fluid that moves heat from outside to inside your home. If the charge is low, there is a leak somewhere, and adding refrigerant without finding the leak is just wasting your money. We find the leak, repair it, and recharge to the manufacturer’s specified level so your heat pump performs like it should.
Heating Repair
Heating Repair is the broad category for fixing any problem that keeps your home from warming up properly, regardless of what kind of system you have. That includes furnaces, heat pumps, ductless mini-splits, and packaged rooftop units common in Dallas homes. Heating Repair in Dallas generally runs between $150 and $700, with the final price depending on the part that failed and how long it takes to access and replace it. We also offer Furnace Repair in Grand Prairie with the same upfront pricing. Brandt HVAC Co Dallas has repaired thousands of heating systems in Dallas since 2003, and every job starts with a clear diagnosis and a written price you approve before work begins.
No Heat Diagnostics
When the thermostat calls for heat and nothing happens, the cause could be a tripped breaker, a failed ignitor, a bad control board, or a dozen other things. Our technicians use multimeters, manometers, and combustion analyzers to trace the failure point rather than guessing. You’ll know what failed, why it failed, and what it costs to fix before we do anything.
Uneven Heating and Short Cycling
Rooms that never get warm, or a furnace that turns on and off every few minutes, point to airflow issues, thermostat problems, or an oversized system. Short cycling in particular wears out components fast and drives up energy bills. We find the underlying cause and correct it so your home heats evenly and your system runs the way it should.
Boiler Repair
Boiler Repair addresses failures in hydronic heating systems that use hot water instead of forced air to heat radiators, baseboards, or in-floor tubing. Boilers are less common in Dallas than furnaces, but many older homes in East Dallas and Lakewood still rely on them, and when a circulator pump fails or a pressure relief valve leaks, you lose heat fast. We also provide Furnace Repair in Balch Springs for homes with forced-air systems. Boiler Repair in Dallas typically runs $150 to $700 for most residential jobs. Brandt HVAC Co Dallas technicians are trained on gas and electric boilers and arrive with the diagnostic tools to identify the problem and a written price to fix it.
Circulator Pump Replacement
The circulator pump pushes hot water from the boiler through your pipes, and when it fails, the boiler fires but the rooms stay cold. Pump failures often announce themselves with a humming noise or a cold spot on the pump body itself. We replace failed pumps with matched units and bleed air from the system so heat moves again.
Pressure and Expansion Tank Service
Boiler pressure that climbs too high or drops to zero usually points to a failed expansion tank or a faulty pressure reducing valve. Either problem can leave you without heat and, in a worst case, damage the boiler itself. We test pressure, inspect the expansion tank, and replace failed components before they cause bigger damage.
Gas Furnace Repair
Gas Furnace Repair covers all problems with natural gas or propane furnaces, from ignitors that won’t glow to gas valves that won’t open to heat exchangers that have cracked. Gas furnaces are the most common heating system in Dallas, and the most urgent repairs tend to involve the gas supply or the ignition sequence. Gas Furnace Repair in Dallas ranges from $150 to $700 for most component replacements. Brandt HVAC Co Dallas uses combustion analyzers to verify safe operation after every Gas Furnace Repair, because a furnace that heats but vents improperly is a danger, not a fix.
Ignitor and Flame Sensor Replacement
The hot surface ignitor glows orange to light the gas, and the flame sensor confirms the flame is actually burning. When either fails, the furnace locks out and refuses to run. These are two of the most common Gas Furnace Repair calls we handle in Dallas, and both are typically completed the same day with parts already on the truck.
Heat Exchanger Inspection
A cracked heat exchanger can leak carbon monoxide into your home, which makes this the one repair where you should never put off a professional inspection. If you hear a rattling sound when the blower starts or notice soot near the burners, call us. We inspect with a camera and combustion analyzer, and if the heat exchanger is compromised, we’ll show you what we found and explain your options honestly.
Furnace Tune Up
A Furnace Tune Up is a preventive service that deep-cleans and calibrates your furnace so it burns fuel efficiently and runs reliably through the Dallas heating season. Most Furnace Tune Up visits in Dallas run $80 to $200, and the work takes about 60 to 90 minutes. Brandt HVAC Co Dallas performs tune-ups on all major brands, including Goodman, Rheem, Trane, and Lennox. Our technicians clean the burners, check gas pressure, test the ignition, measure temperature rise, inspect the heat exchanger, and verify carbon monoxide levels are safe before leaving.
Burner Cleaning and Gas Pressure Calibration
Burners collect dust and corrosion during the idle months, and when they light unevenly, your furnace wastes gas and produces soot. We remove and clean the burners, then set gas pressure to the manufacturer’s specification. This single adjustment often improves efficiency enough to pay for the tune-up over the course of a season.
Safety System Verification
Your furnace has multiple safety switches designed to shut it down if something goes wrong: the limit switch, pressure switch, rollout switch, and flame sensor. During a Furnace Tune Up, we test every one of them and verify they trip at the right thresholds. A furnace that heats without working safety controls is a risk no homeowner should accept.
Emergency Furnace Repair
Emergency Furnace Repair is what you need when the furnace dies in the middle of a Dallas cold snap and waiting until tomorrow is not acceptable, especially with children, elderly family members, or a medical condition in the home. We answer the phone 24 hours a day, 7 days a week, including holidays. Emergency Furnace Repair in Dallas costs the same range as standard repairs, $150 to $700, because we do not charge overtime or after-hours fees. Brandt HVAC Co Dallas keeps service trucks stocked with common repair parts so most emergency calls are resolved in one visit.
After-Hours Availability
Furnaces never fail at a convenient time, which is why we staff phones with live people around the clock. You will never get a voicemail or an automated phone tree. You’ll talk to a person who can dispatch a technician to your Dallas home, and we’ll text you the technician’s name and photo before they arrive, even at 2 a.m.
Same-Day Repair Targets
Most Emergency Furnace Repair calls in Dallas are completed the same day, often within a few hours of your call. We prioritize no-heat calls at any hour, and the written guarantee applies to emergency repairs the same way it applies to scheduled work. If we fix it and it fails within 365 days, we return free of charge.

AfterBrands We Service
Our technicians work on Trane furnaces every week in Dallas. Trane units are built for long service lives, but their ignitors and pressure switches still wear out, and we keep those parts stocked to get your Trane heating again the same day. We know the common failure points on Trane models and quote repairs using OEM parts whenever possible.
Lennox and Rheem furnaces are also common across Dallas neighborhoods from Richardson to Furnace Repair - Duncanville. Lennox systems often need attention to their control boards and draft inducer motors, while Rheem call-outs frequently involve limit switch trips from restricted airflow. Goodman units, widely installed in Dallas in the last two decades, tend to age through ignitor and flame sensor failures that we repair regularly. Whether you have a Trane, Lennox, Rheem, Goodman, or any other make, we can help.
Signs You Need a Pro Right Now
- Your furnace is blowing cold air. This usually means the burners are not lighting or the flame sensor is failing. Running the blower without heat just wastes electricity and leaves your home cold.
- You smell gas or detect a sulfur-like odor. If you smell gas, leave the house and call your gas utility first, then call us. A furnace that leaks gas at the valve or supply line is dangerous and needs immediate professional attention.
- The furnace turns on and off every few minutes. Short cycling can mean a failing limit switch, a dirty filter, or an overheating heat exchanger. The strain shortens furnace life and drives up your gas bill.
- You hear banging, rattling, or screeching during operation. Rattling can point to a cracked heat exchanger, which can leak carbon monoxide. Screeching often means a failing blower motor. Neither resolves itself.
- Your energy bills spiked without explanation. A furnace that suddenly burns more gas than last winter is fighting against a problem. We identify the cause during a diagnostic visit, not by guesswork.
If any of these signs sound familiar, call (325) 312-3269. We’ll schedule a technician for your Dallas home and give you a written price before any repair work starts.
