AC Service

AC Service means a thorough inspection and tune-up of your cooling system, not a quick glance at the thermostat. A full AC service catches small problems before they become $650 repairs. In Dallas, where June through September pushes systems to run 18 hours a day, an annual service call is the single best way to avoid a mid-July breakdown that requires AC Repair in Dallas. Most AC service calls at Brandt HVAC Co Dallas run $80 to $200, depending on the system size and its condition. We inspect refrigerant levels, electrical connections, condensate drains, and airflow, then hand you a written report of what we found.

What’s included in a full service

We check the capacitor, contactor, thermostat calibration, and coil condition. We also measure the temperature drop across your evaporator coil, because a weak temperature split is often the first sign of a slow refrigerant leak.

You’ll get a written breakdown that separates what’s working, what’s wearing, and what needs attention now. No pressure. Just information you can act on.

When to schedule AC service in Dallas

Schedule service in early spring, before temperatures climb past 90 degrees. Technicians can take their time, parts are in stock, and you won’t be waiting behind a line of emergency calls.

If you missed that window, schedule anyway. A late tune-up is still far cheaper than a compressor replacement in August.

AC Unit Repair

AC Unit Repair covers the mechanical and electrical fixes that keep your system running: fan motors, contactors, thermostats, circuit boards, and wiring. Most AC unit repairs in Dallas fall between $150 and $650, depending on how much AC Repair costs for the part and the time required. A failed condenser fan motor, for example, runs higher than a burnt contactor. At Brandt HVAC Co Dallas, you’ll get a written price before any work starts. If the repair requires a part you didn’t know existed, we’ll show you the failed component and explain what it does in plain language before we replace it.

Common repairs we make weekly

Condenser fan motor failures, contactor burnouts, and thermostat miswiring are the most frequent calls we run in Dallas. Each one has a distinct symptom, but all three share a trait: they get worse the longer they’re ignored.

We stock common replacement parts for Trane, Lennox, and Goodman systems on our trucks, which means many repairs are completed on the first visit.

Repair vs. replace in Dallas

If your system is under 10 years old and the repair is under $650, fix it. That’s the honest math for most Dallas homes. We’ll tell you when a repair no longer makes financial sense, and we won’t upsell you into a new unit.

Every repair includes a written guarantee. If the same repair fails within 365 days, we return at no charge under our 365-Day Done Right Promise. No argument, no additional fee.

AC Capacitor Replacement

AC Capacitor Replacement is one of the most common repairs we make in Dallas. A capacitor is a small cylinder inside the outdoor unit that stores and releases electrical energy to start the fan motor and compressor. When it fails, the system either won’t start at all or it hums and shuts off. In Dallas heat, capacitors fail faster than in cooler climates because sustained high temperatures degrade the internal dielectric material. Most capacitor replacements run $150 to $300, parts and labor included, which puts them on the lower end of our AC Repair - Duncanville and Dallas service range.

Warning signs of a failing capacitor

The outdoor unit hums but the fan doesn’t spin, or the system takes multiple attempts to start. You might also notice the fan spinning slower than it should, even when the compressor is running.

If you hear a humming sound and the fan isn’t moving, shut the system off at the thermostat. A stalled motor with a failed capacitor can overheat and cause more expensive damage, including a burned-out compressor.

Why a correct match matters

Capacitors are rated by microfarads and voltage, and the replacement must match the original spec exactly. A mismatched capacitor can shorten the life of the compressor or fan motor. Our technicians test the old capacitor’s actual output against its rated value, then install a replacement that matches the manufacturer’s specification.

This is not a job for guesswork, and it’s not worth gambling on a universal part. The wrong capacitor can turn a $200 repair into a $2,000 compressor failure.

AC Recharge

AC Recharge means refilling the refrigerant, the fluid that moves heat out of your home. Low refrigerant is one of the most common causes of warm air from the vents in Dallas, but it’s also the most misunderstood. Refrigerant doesn’t get “used up.” If your system is low, it has a leak somewhere, and that leak needs to be found before or during the recharge. A straightforward AC recharge in Dallas runs $150 to $400, depending on how much refrigerant is needed and how accessible the leak is. At Brandt HVAC Co Dallas, we locate the leak, repair it when possible, and then recharge the system to the manufacturer’s exact specification.

How to know if you need a recharge

Warm air at the vents, ice forming on the copper lines outside, or a hissing sound near the indoor coil are all signs of low refrigerant. Ice on the lines is a common misdiagnosis, homeowners think it means the system is “cold enough,” but it actually means the coil is frozen and starving for refrigerant.

If you see ice, turn the system off and call us. Running a frozen system can destroy the compressor.

Why we find the leak first

Recharging without finding the leak is like refilling a flat tire without patching the hole. Some companies skip this step because it takes longer and requires more skill. We use electronic leak detectors and UV dye to find the source before we recharge.

Sometimes the leak is at a Schrader valve, an inexpensive fix. Sometimes it’s in the evaporator coil, which is more involved. Either way, you’ll know before we do the work, because you’ll have a written price first.

Emergency AC Repair

Emergency AC Repair in Dallas is about more than comfort. When the heat index climbs past 105, a failed AC system is a genuine health risk, especially for older adults, infants, and anyone with respiratory conditions. That’s why we answer the phone with a live person 24 hours a day, 7 days a week, including holidays. Emergency AC repair in Dallas generally costs the same as a standard repair, $150 to $650, with no overtime markup, as detailed in our AC Repair Maintenance Checklist for Dallas Homeowners. That’s a Brandt HVAC policy: emergency service doesn’t cost extra. Call (325) 312-3269, tell us what’s happening, and we’ll dispatch a technician.

What counts as an emergency

No cooling at all when the outdoor temperature is above 90, a burning smell from the unit, or a system that trips the breaker repeatedly. These are calls we treat as priority, because they carry real risk beyond comfort.

An AC that’s running but not keeping up, like holding 80 degrees instead of 74, is urgent but not the same priority. We’ll get to you fast either way, and we’ll be honest about where your call falls in the queue.

What to do while you wait

Turn the system off at the thermostat if you smell burning or hear grinding. Close blinds and curtains on sun-facing windows. Use fans to keep air moving. Don’t open the outdoor unit and start poking around, especially near the capacitor or wiring. A capacitor can hold a charge even when the power is off.

If you have someone in the home who is medically vulnerable, tell the person who answers the phone. We prioritize those calls.

AC Not Blowing Cold Air

AC Not Blowing Cold Air is the most common call we get in Dallas between May and October. The cause can range from a dirty air filter to a failed compressor, which is why the first step is diagnosis, not guesswork. Most repairs for an AC that’s not blowing cold air in Dallas run $150 to $650, and many of them, like a clogged condensate line or a failed capacitor, fall under $350. At Brandt HVAC Co Dallas, we don’t charge by the hour while we figure it out. You get a written price for the repair, based on our diagnosis, before we touch a wrench.

Check these before you call

Replace the air filter if it’s dirty. A clogged filter restricts airflow, which causes the evaporator coil to freeze, which makes the air warm. Then check the thermostat settings and make sure the outdoor unit’s breaker hasn’t tripped.

Those three things, filter, thermostat, and breaker, solve about one in ten “not blowing cold air” calls. When they don’t solve it, that’s when you call us.

If the problem is bigger than a filter

Low refrigerant, a failed compressor, or a failed reversing valve on a heat pump are all causes we see regularly in Dallas. Each has a different fix and a different price. What they share is that they won’t fix themselves, and they tend to get more expensive the longer the system runs with the problem present.

One note: if your system is blowing cold air but not enough of it, that’s an airflow problem, not a refrigerant problem. We’ll measure static pressure to find out which.

Brands We Service

We service Trane systems regularly across Dallas, and we’re familiar with the brand’s specific compressor and coil designs. Our technicians know Trane’s common failure points, including the contactor and run capacitor, and we stock replacement parts that match Trane’s original specifications.

We work on Lennox and Goodman units just as often. Lennox systems, especially the higher-efficiency models, require careful attention to their variable-speed components. Goodman units are common in Dallas homes, and we know their strengths and their weak points well. We service Rheem systems too, including their heat pumps. Whether you have a Trane, Lennox, Goodman, Rheem, or any other make, we can help.

Signs You Need a Pro Right Now

• Warm air from the vents. If the air coming from your registers is warmer than the air in the room, something is wrong with the cooling cycle. It could be low refrigerant, a failed compressor, or a duct issue. Either way, running the system won’t fix it.
• Ice on the refrigerant lines. Ice anywhere on the indoor or outdoor unit means the system is frozen, and a frozen system can’t cool your home. Continuing to run it can damage the compressor, and that’s the most expensive part to replace.
• A burning smell from the unit. A burning odor often means an electrical component has overheated, like a capacitor, contactor, or fan motor. This is a fire risk, not just a comfort issue. Turn the system off and call us.
• Humming or clicking sounds without startup. A hum that doesn’t turn into a running fan points to a failed capacitor or a seized motor. A rapid clicking at the thermostat may mean a control board issue. Both need a technician’s attention.
• The system runs constantly but the house won’t cool. If your AC cycles without stopping and the house stays warm, you might have a refrigerant leak or a failing compressor. This pattern drives up your electric bill while delivering no comfort, and it stresses every component in the system.

Our Process, Step by Step

1. 1
   You call, a person answers. When you call (325) 312-3269, a live person picks up, day or night. We ask what’s happening, get your Dallas address, and schedule a visit. Before the technician arrives, you’ll receive their name and photo by text or email.
2. 2
   The technician arrives and identifies themselves. Your technician arrives in uniform with a photo ID badge. If the person at your door doesn’t match the name and photo we sent, you don’t have to open the door. That’s the Threshold Verified standard, and it’s non-negotiable for us.
3. 3
   We diagnose and show you the problem. We test the system with the proper meters and gauges, not just a quick visual. If a part failed, we’ll show it to you and explain what it does. You’ll understand what’s broken and why.
4. 4
   You approve a written price. Before any work starts, you’ll have the total price in writing. Parts, labor, everything. No surprises at the end, no “we found something else” after the fact. If you don’t approve the price, no work happens.
5. 5
   We complete the repair and guarantee it. After the repair, we test the system and show you the results. Every repair includes a written guarantee. If the same repair fails within 365 days, we come back at no charge under our 365-Day Done Right Promise.
