Same-Day AC Repair — $79 Diagnostic | Mabank & DFW

When your AC fails in a Texas summer, you don't have hours to wait. Eric's Home Services dispatches same-day for AC repair across Mabank, Cedar Creek Lake Area, and the full DFW metroplex — diagnosing the actual problem with a full 12-point inspection, quoting upfront in writing at flat-rate pricing, and fixing it right the first time. $79 diagnostic fee (waived when you book the repair). No surprise charges, no 'while-I'm-here' add-ons, no mystery line items. Just an honest tech in a clean truck — usually Eric, Brad, or a senior team member, never a subcontractor.

Common AC Problems We Fix Daily

Most AC failures fall into a handful of repeatable patterns. After 20+ years in the HVAC industry and thousands of service calls across Texas, our diagnostic process catches them fast. Each problem below links to a full diagnostic guide if you want to troubleshoot before calling:

• AC running but not cooling — usually low refrigerant, dirty coil, or a failing capacitor
• AC not blowing cold air — refrigerant loss, frozen coil, or thermostat wiring
• Outdoor unit won't turn on — typically a blown capacitor, failed contactor, tripped float switch, or breaker issue
• Frozen evaporator coil — restricted airflow from a clogged filter, dirty coil, or a refrigerant leak
• Loud grinding, buzzing, or squealing — failing motor bearings, loose blower wheel, or contactor chatter
• Thermostat not working — dead batteries, blown low-voltage fuse, or wiring issue
• Short cycling (turning on and off rapidly) — oversized system, dirty flame sensor, thermostat placement issue, or overheating
• Water leaking from indoor unit — clogged condensate drain, rusted-through pan, or tripped float switch
• Warm air from vents — refrigerant loss, blown breaker, frozen line set, or wrong thermostat mode
• Weak airflow from vents — clogged filter, blower motor issue, or ductwork problem
• Bad smells from vents — musty (coil growth), burning (electrical urgent), chemical (refrigerant leak)
• High indoor humidity despite AC running — oversized system, low refrigerant, or dehumidification needed

AC Repair Pricing — Complete Cost Breakdown

Honest answer: it depends on what's broken. But because we hear "how much?" before anyone has even looked at the unit, here's the truthful breakdown of what reputable shops in Mabank and DFW charge for the most common repairs:

• Diagnostic / service call: $79 (waived if you book the repair). After-hours emergency: $129.
• Capacitor replacement: $350-$850 (varies by system size, brand, and quality tier)
• Contactor replacement: $300-$800 (varies by electrical configuration and accessibility)
• Refrigerant recharge (R-410A): $90-$350 per pound + $140-$240 labor. R-22 (older systems) runs significantly higher due to phase-out.
• Refrigerant leak repair: $400-$1,800 depending on leak location. Simple service port leaks are cheaper than evaporator coil leaks.
• Condensate drain clear: $120-$180
• Float switch replacement: $180-$280
• Blower motor replacement: $800-$4,200. Standard PSC motors are at the low end; ECM (variable-speed) motors + control modules can reach the high end.
• Blower wheel cleaning / rebalance: $220-$380
• Evaporator coil replacement: $1,400-$2,400
• Condenser coil cleaning (professional): $180-$320
• Compressor replacement: $1,800-$3,500. If still under manufacturer warranty, you often pay only labor + related parts (~$800-$1,400).
• Thermostat replacement: $200-$650 (basic to smart)
• Control board / defrost board replacement: $480-$720
• Full refrigerant line-set replacement: $800-$1,600

If anyone quotes you wildly outside these ranges (high OR low), get a second opinion. We give second opinions for free — bring us another company's quote and we'll verify it before you spend thousands on a repair you might not need.

The $79 Diagnostic — And When It's Free

Our diagnostic is a flat $79 (waived when you book the repair). It's genuine diagnostic work — we measure refrigerant pressures, test capacitor microfarads with a meter, check contactor pitting, verify thermostat calibration, inspect the evaporator coil visually, and check every safety switch. That's 30-45 minutes of real work. Here's why we charge for it (and when we don't):

• The tech's drive time and labor costs real money. A ‘free’ service call is loss-leader pricing, which means the company has to make it up somewhere — usually by overquoting the repair (30-50% padding) or inventing ‘urgent’ additional problems.
• The $79 is waived when you book the repair. So if we do the work, the diagnostic is effectively free anyway — but without the pressure to invent repairs.
• Second-opinion diagnostics are FREE. If you already have a quote from another company and want us to verify it, no diagnostic charge. Bring us the paperwork.
• Simple fixes are FREE. If we get to your home and the fix takes under 5 minutes with no parts, we don't charge the diagnostic. Period. Details below.

Simple Fix Guarantee — If It's Something Simple, It's Free

Most HVAC companies charge you $79-$179 to walk in your door even if the “problem” is a dead thermostat battery or a tripped breaker. We don't. If the fix takes under 5 minutes with no parts, we skip the diagnostic charge and drive away without billing you. Here's the bright line so you know what qualifies:

• Dead thermostat battery — free
• Tripped breaker (main panel or disconnect) — free
• Tripped float switch that just needs a reset — free
• Air filter clogged to failure — we swap and go — free
• Thermostat wired incorrectly after a DIY replacement — free
• Someone bumped the furnace power switch off — free

What doesn't qualify: component replacement (capacitor, contactor, motor, gas valve), refrigerant work, anything requiring meter readings and diagnostic judgment, second-visit calls, or rooftop/difficult attic access work. Those get standard flat-rate pricing quoted in writing before we touch anything. But if it turns out to be genuinely simple — we don't charge. This isn't marketing language; it's a policy the tech is trained to honor at the door.

Our AC Repair Diagnostic Process

We don't pull a "looks like the compressor" line and walk away with your card. Every call follows the same disciplined 6-step process:

• 1. Pre-arrival text — you get a message with the tech's name, photo, and ETA window before we arrive. You know who's coming to your door.
• 2. Symptom interview — we ask when the problem started, what you've tried, whether the system was maintained. Context matters for accurate diagnosis.
• 3. Full 12-point system diagnostic — refrigerant pressures (high and low side), capacitor microfarads (measured vs rated), contactor pitting and amperage, compressor amp draw and start behavior, blower motor amp draw, thermostat calibration, evaporator coil visual inspection, condenser coil condition, condensate drain and float switch, refrigerant subcool/superheat, temperature split (supply vs return), electrical connections.
• 4. Upfront written quote — flat-rate pricing, signed off by you before any work begins. No ‘while I’m here’ surprise add-ons.
• 5. Repair performed — done right with OEM-spec parts. Most repairs completed same visit (we stock capacitors, contactors, common motor sizes, refrigerant on the truck).
• 6. Post-repair verification — we re-test pressures, supply/return temperatures, and amp draw to prove the fix actually worked. Written report of measurements given to you.

When to Repair vs. Replace Your AC

We'll tell you the truth — even if it costs us the repair ticket. Rule of thumb we use:

• AC under 8 years old: almost always worth repairing, even for major work like compressor replacement (often still under warranty)
• AC 8-12 years old: compare repair cost to replacement cost. Repair under 30% of replacement = repair. Repair 30-50% = judgment call based on other symptoms. Repair over 50% = replace.
• AC 12+ years old: replacement usually wins on lifetime cost. Efficiency has dropped 10-15%, other components statistically likely to fail within 2-3 years, and repair invoices tend to compound.
• R-22 (Freon) system at any age: replacement almost always wins. R-22 phased out; new stock costs $90-$350 per pound (vs $40-$80 for R-410A). One leak repair often exceeds 40% of replacement cost.
• Compressor failure on system over 10 years old: replace. Compressor swap costs $1,800-$3,500 with no warranty on the surrounding aged components.
• Multiple major repairs in a single year: replace. If you've spent $1,500+ on repairs in 12 months, that money should go toward a new system instead.

We'll give you the honest math both ways during the diagnostic — repair cost, replacement cost, and expected next-3-years cost for each path. Then you decide. See our AC installation page if replacement makes sense.

Emergency AC Repair — What Qualifies

Same-night dispatch is available for true no-cool emergencies. What we treat as an emergency:

• Indoor temperature above 85°F with vulnerable occupants (infants, elderly, medical conditions)
• Complete system failure — no airflow at all
• Burning electrical smell from the air handler or condenser
• Visible smoke from the unit
• Water actively leaking through the ceiling from the air handler
• Refrigerant leak loud enough to hear (health/safety concern)

See our 24/7 emergency AC repair page for the full protocol. Anything else, we can usually get to you first thing the next morning at standard rates rather than emergency rates ($79 vs $129).
