Why Brandt HVAC Is Murphy’s Preferred AC Maintenance Company
We’ve been working Murphy’s neighborhoods long enough to recognize the house models before we pull up. The brick-veneer, slab-on-grade tracts built 2000 – 2012. The attic-mounted air handlers sweating through another July. The original R-22 systems that homeowners hope we can just “top off” – a conversation we have more often in Murphy than in neighboring Plano, where older homes already cycled through replacement, or Wylie, where newer builds run R-410A.
Our AC Maintenance team is held to the Threshold Verified standard. That means you get a name, photo, and background-check confirmation before anyone arrives. The technician who walks up your driveway in Murphy is the exact person you were told to expect. If they aren’t, that visit is on us and we make it right.
Every job starts with a written price. No work begins until you see the cost in writing and agree to it. Every repair carries a written guarantee under our 365-Day Done Right Promise – if it fails, we return at no charge.
Phones are answered by a live person, 24/7. No automated trees. No callback queues.
HVAC Maintenance in Murphy
HVAC Maintenance in Murphy means keeping cooling and heating equipment running through North Texas extremes – summer design temperatures above 100°F with punishing humidity, and ice storms that can freeze exposed refrigerant lines on north-facing units. For most Murphy homeowners, we recommend two visits yearly: a cooling check in spring before the heavy load hits, and a heating check in fall before the first freeze.
A standard HVAC maintenance visit in Murphy costs $80 – $200. That’s a flat, upfront price. We inspect electrical connections, test capacitors and contactors, measure refrigerant pressures, clean condensate drains, check blower motor amp draw, and verify thermostat calibration. You’ll get a written report of what we found, what we did, and what to watch for.
What We Check in Attic-Mounted Systems
Murphy’s slab-on-grade homes put air handlers and ductwork in the attic, where summer temperatures can exceed 140°F. We inspect condensate pans and safety switches – a clogged drain here doesn’t just cause a service call, it can flood a ceiling. We also measure static pressure across the evaporator coil, because Murphy’s original ductwork was often sized for the bare minimum, and that restriction shows up as strain on your blower motor.
When Maintenance Becomes a Replacement Conversation
Because Murphy’s housing stock is essentially one generation – tract homes built 2000 – 2012 with attic-mounted air handlers – a single HOA or subdivision-wide replacement wave hits at once, and mid-summer R-22 recharge requests are often refused outright since virgin R-22 was banned from production after January 2020. If your system is low on refrigerant, we’ll show you the leak detection results and explain why a recharge may cost more than the unit is worth.
AC Tune Up in Murphy
AC Tune Up in Murphy is what most homeowners book when they want cooling-specific service before the heat arrives. An AC tune-up costs $80 – $200 and focuses on the outdoor condenser, indoor evaporator, and the refrigerant circuit that moves heat out of your home. We recommend scheduling in March or April, before Murphy’s first sustained 95°F days force your system into continuous runtime.
Our technicians are not paid on what they sell. The written report you receive lists findings only – no pressure to add services you didn’t request. If we find something that needs attention, we’ll explain it in plain language and give you a separate written price if you want the work done.
Condenser Cleaning and Coil Inspection
North Texas cottonwood and pollen season hits Murphy hard in late spring. We clean condenser coils and straighten fins so your unit can reject heat efficiently. A dirty condenser in July Murphy heat forces your compressor to work harder and longer, shortening its life.
Refrigerant Testing and Leak Detection
We measure superheat and subcooling to verify proper refrigerant charge. If levels are low, we use electronic leak detection to find the source. In Murphy’s 2000-era subdivisions, we often find pinhole leaks in evaporator coils that have reached end of life – another reason the tune-up sometimes turns into a replacement discussion.
Trusted Brands We Service in Murphy
We maintain and repair all major residential HVAC brands found in Murphy homes: Trane, Lennox, Goodman, and Rheem among them. Our Dallas-Fort Worth parts operation stocks common capacitors, contactors, and blower motors for these brands, so most Murphy maintenance visits don’t require a return trip. If your system needs a part we don’t carry, we’ll tell you upfront and give you a firm date for completion. We also service Carrier, York, Daikin, Bryant, and American Standard equipment.
Common AC Maintenance Problems We See in Murphy Homes
- Undersized return ductwork causing high static pressure. Murphy’s builder-grade installations often used the minimum duct size. We measure static pressure during every tune-up; readings above 0.5 in. w.c. mean your blower motor is working overtime and your evaporator coil isn’t getting enough airflow.
- Clogged condensate drains in attic-mounted air handlers. The combination of Murphy’s humid summers and hot attic temperatures creates algae growth in drain lines. We clear the primary drain, test the backup safety switch, and treat the pan to slow future growth.
- Weak or failing capacitors on original 2000s compressors. Capacitors degrade with heat and age. In Murphy’s 2005-era systems, we’re replacing them routinely during maintenance visits before they fail completely and take the compressor with them.
- Heat pump refrigerant lines cracked after ice storms. Murphy’s periodic ice storms freeze exposed lines on north-facing units. We inspect line insulation and refrigerant levels, and we recommend protective measures for vulnerable installations.
Pricing for AC Maintenance in Murphy, TX
| Service | Price Range in Murphy |
|---|---|
| AC Tune Up | $80 – $200 |
| HVAC Maintenance | $80 – $200 |
These are flat prices, not hourly rates. What you see is what you pay.

We give you the price in writing before any work starts. Estimates are free. Call (984) 538-9003 for yours.
Replacement conversations are different. If your 2004-era R-22 system needs major work, we’ll show you the math: recharge cost versus replacement cost, factoring in efficiency gains and current rebate programs. You’ll get a written fixed price for either path, with no pressure to choose one over the other.

FAQs About AC Maintenance in Murphy
We can test your refrigerant levels, but we won’t recharge an R-22 system without first finding and discussing the leak. Virgin R-22 hasn’t been produced since January 2020, so reclaimed refrigerant costs have risen dramatically – often making a recharge more expensive than the remaining value of your 2004 unit. We’ll show you leak detection results and give you a written price for both repair and replacement options. Call (984) 538-9003 and we’ll walk you through the numbers.
Static pressure measures how hard your blower motor works to push air through your ductwork. Murphy’s 2000-era tract homes were built with minimum-size ducts, and many run 0.7 to 0.9 in. w.c. – well above the 0.5 target. High static pressure burns out blower motors, freezes evaporator coils, and eventually kills compressors. We measure it during every tune-up because it’s the hidden problem behind many “my AC can’t keep up” calls in Murphy subdivisions.
A standard AC tune-up includes electrical testing, capacitor and contactor inspection, refrigerant pressure measurement, condenser coil cleaning, condensate drain clearing, blower motor amp draw testing, and thermostat calibration. For Murphy’s climate, schedule once yearly in spring, before sustained heat arrives. The cost is $80 – $200 with a written report of findings. Call (984) 538-9003 to book.
Probably not tonnage alone. Murphy’s original builder-grade systems were often single-zone units fighting two-story or split floor plans with poor airflow balance. Your neighbor’s new system likely includes proper duct redesign, possibly zoning, and definitely a modern SEER2 compressor that modulates output rather than running full-blast or nothing. A like-for-like swap of your 2006 unit without addressing ductwork often disappoints. We’ll assess your home’s load calculation and duct design if you’re considering replacement.
Many Murphy homes use heat pumps for both heating and cooling, and our climate is hard on them. Summer design temperatures above 100°F with high dewpoints push cooling capacity to the limit, while periodic ice storms can freeze and crack exposed refrigerant lines on north-facing units. A heat pump check during your AC tune-up verifies defrost controls, supplemental heat operation, and line insulation integrity before winter arrives.
