For AC emergencies, call 972-291-0740. We prioritize cooling calls during summer heat because we know your family’s health and safety depend on reliable air conditioning.
Dallas AC Repair Services
Expert Diagnosis and Lasting Solutions
Air conditioning systems require professional expertise for accurate diagnosis and reliable repairs. Our certified technicians service all AC types and brands, understanding the specific maintenance and repair requirements each system presents.
Common AC Problems We Fix:
Refrigerant leaks reduce cooling capacity and efficiency while potentially damaging compressors. Modern refrigerants require professional handling and EPA-certified technicians. We locate leaks, repair them properly, and recharge systems to manufacturer specifications.
Compressor failures affect your system’s ability to cool effectively. Compressors are the heart of AC systems, and failures often indicate other problems requiring attention. We diagnose compressor issues and explain repair versus replacement options clearly.
Electrical problems including failed capacitors, contactors, or wiring issues prevent proper AC operation. These components wear over time and require professional replacement for safe, reliable operation.
Thermostat malfunctions prevent proper system control and comfortable temperatures. Problems range from dead batteries to failed units requiring replacement. We diagnose thermostat issues and provide appropriate solutions.
Dirty or frozen coils reduce efficiency and cooling capacity. Evaporator coils inside and condenser coils outside require regular cleaning for optimal performance. Frozen coils indicate airflow restrictions or refrigerant problems requiring professional attention.
Blower motor problems affect air circulation throughout your home. Failed motors, worn bearings, or belt issues prevent adequate airflow, reducing comfort and efficiency.
Drainage problems cause water leaks from indoor units. Clogged condensate lines, failed pumps, or frozen coils create water accumulation requiring professional cleaning and repair.
When AC Repair Makes Sense:
Systems under 10-12 years with isolated component failures usually justify repair costs. Single part replacements on well-maintained equipment typically provide cost-effective solutions. We provide honest assessments helping you decide between repair and replacement based on system age, condition, and repair costs.
Annual AC Maintenance & Tune ups
Preventive Service Protecting Your Investment
Regular AC maintenance prevents breakdowns, ensures efficient operation, and extends equipment life significantly compared to neglected systems. Spring maintenance before cooling season catches problems during mild weather before extreme heat when system failures create family emergencies.
Comprehensive Maintenance Services:
Complete system inspection checks all components for wear, damage, or developing problems. Early identification prevents expensive emergency repairs during peak cooling season.
Refrigerant testing verifies proper charge for optimal efficiency and cooling capacity. Low refrigerant indicates leaks requiring professional repair before recharging.
Coil cleaning removes dirt and debris from evaporator and condenser coils. Clean coils transfer heat effectively, maintaining efficiency and preventing premature system failure.

AC Installation Services in Dallas
Professional Installation for Long-Term Comfort and Efficiency
New AC installation requires careful planning, proper sizing, and professional execution, ensuring optimal performance, efficiency, and longevity.
Signs You Need AC Replacement:
System age and declining efficiency go hand in hand. AC systems typically last 12-15 years with proper maintenance. Systems approaching this age lose efficiency, require frequent repairs, and lack modern features. Replacement with high-efficiency models often recovers costs through reduced energy bills.
Frequent expensive repairs indicate approaching system failure. When repair costs exceed half the replacement value, or when multiple major components fail, replacement typically provides better long-term value.
Rising cooling bills without increased usage suggest declining efficiency from aging components or refrigerant issues. Modern AC systems operate at significantly higher efficiency levels (14-20+ SEER) compared to older units (8-10 SEER).
Inadequate cooling despite repairs indicates undersized equipment, ductwork problems, or systems unable to meet your home’s demands. Proper replacement sizing ensures adequate cooling capacity for reliable comfort.
Using R-22 refrigerant in older systems creates challenges. This discontinued refrigerant has become expensive and difficult to obtain. Systems requiring R-22 repairs or recharge often make better candidates for replacement with modern systems using current refrigerants.
Our AC Installation Process:
A comprehensive home assessment calculates proper equipment sizing, accounting for square footage, insulation, windows, orientation, ceiling heights, and local climate. Oversized systems cycle too frequently, wasting energy and reducing dehumidification. Undersized systems run constantly without achieving comfortable temperatures. Professional sizing ensures optimal performance.
Equipment selection guidance helps you understand SEER efficiency ratings, single-stage versus variable-speed operation, standard systems versus heat pumps, and features affecting comfort and operating costs. We explain options clearly, helping you make informed decisions matching your needs and budget.
System options include traditional central AC providing whole-home cooling, ductless mini-split systems perfect for additions or homes without ductwork, heat pumps offering year-round heating and cooling efficiency, and high-efficiency models with advanced features for maximum comfort and energy savings.
Professional installation follows manufacturer specifications and local codes. Our certified technicians handle equipment removal, new system placement, refrigerant line installation, electrical connections, ductwork modifications if needed, thermostat installation, and complete system testing. Quality installation protects warranty coverage and ensures designed performance.
System startup and testing verifies proper operation, including correct refrigerant charge, adequate airflow throughout your home, accurate thermostat operation, proper drainage, and optimal system performance. We test thoroughly before completing installation.
First-Year Advantage Plan Included:
Unlike companies that install and disappear, we include our Advantage Plan maintenance during the first year. New AC systems often need adjustments as they break in and as your family’s usage patterns become clear. During your two included HVAC visits, we fine-tune your equipment for optimal performance, provide filters, and demonstrate the value of ongoing professional care.
Modern AC Advantages:
High-efficiency models (16-20+ SEER) reduce cooling costs 30-50% compared to older systems, variable-speed air handlers provide better humidity control and quieter operation, smart thermostats optimize comfort while reducing energy waste, advanced diagnostics simplify future service and troubleshooting, and longer warranties protect your investment.
