Air conditioning systems are complex machines with multiple components that must work together precisely to deliver reliable cooling. When something goes wrong—and eventually, something always does—you need a repair service with the knowledge and experience to diagnose problems accurately and fix them completely. Over our 40 years in business, we've seen virtually every AC problem that can occur, and we've developed systematic diagnostic approaches that identify root causes rather than just treating symptoms.

Many AC problems have similar symptoms but completely different causes. For example, an air conditioner that won't cool could be suffering from a refrigerant leak, a failed compressor, a clogged evaporator coil, a faulty expansion valve, electrical problems, or ductwork issues. Inexperienced technicians might jump to conclusions or recommend unnecessary repairs. Our methodical diagnostic process uses advanced testing equipment, careful observation, and decades of troubleshooting experience to pinpoint the actual problem before we recommend solutions.
The quality of your AC repair directly affects how long your system continues to run, how efficiently it operates, and whether the same problem recurs. Poor repair work using incorrect refrigerant charges, inadequate electrical connections, or low-quality parts might get your system running temporarily but often leads to premature failure and additional expenses. We take pride in doing repairs right the first time, using proper procedures and quality components that deliver lasting results. Experience repair service that actually fixes problems.

Refrigerant leaks are among the most common AC problems we encounter, and they're also among the most commonly misdiagnosed. If your air conditioner isn't cooling properly, many technicians simply add more refrigerant without finding and fixing the leak—a temporary solution that wastes your money and damages the environment. Our approach is different. We use electronic leak detectors, UV dye, and bubble testing to locate even tiny leaks in coils, line sets, and connections. Once found, we repair the leak properly, evacuate the system, and recharge it with the precise amount of refrigerant specified by the manufacturer.
Proper refrigerant charging requires more than just adding refrigerant until the pressure gauge reads a certain number. It involves measuring superheat and subcooling, checking airflow across the coils, verifying proper expansion valve operation, and ensuring the entire system operates within manufacturer specifications. This level of precision ensures your AC runs efficiently and reliably rather than limping along with an improper charge that will shorten its lifespan.
Older air conditioners using R-22 refrigerant (commonly called Freon) face additional challenges because R-22 production ended in 2020, making it expensive and increasingly difficult to obtain. If your system requires significant refrigerant addition due to a major leak, we'll discuss whether repair or replacement makes better financial sense. We offer flexible financing options to help manage unexpected repair costs.
The compressor is your air conditioner's heart—it circulates refrigerant through the system and creates the pressure differences that make cooling possible. When compressors fail, it's often dramatic with loud noises, complete system shutdown, or circuit breaker trips. However, compressors can also fail gradually with symptoms like reduced cooling capacity, hard starting, or excessive cycling. Our diagnostic testing includes checking compressor amperage draw, testing starting components, measuring discharge and suction pressures, listening for internal mechanical sounds, and verifying proper lubrication and cooling.
Compressor problems have various causes including electrical issues like capacitor failures or contactor problems, mechanical failures from normal wear or lack of lubrication, refrigerant problems including undercharging or overcharging, restricted airflow causing overheating, and contamination from previous repairs. We diagnose the root cause to determine whether the compressor can be saved through repairs to supporting components or needs replacement.
Modern air conditioners rely on complex electrical and electronic control systems that manage everything from compressor operation to fan speeds and defrost cycles. Electrical problems can cause complete system failures or intermittent issues that are frustrating to diagnose. Common electrical problems include failed capacitors that prevent motors from starting, worn contactors that don't energize reliably, bad thermostat wiring or settings, tripped breakers or blown fuses, burned disconnect switches, control board failures, and sensor problems that provide incorrect system feedback.
Our electrical diagnostics go beyond simple voltage checks. We test component amperage under load, verify control signal voltages, check safety switch operation, measure capacitor microfarads, inspect all connections for corrosion or looseness, and trace circuits when problems aren't immediately obvious. This thorough approach identifies electrical issues that less experienced technicians might miss, preventing callbacks and ensuring reliable system operation.
Proper airflow is essential for efficient AC operation and adequate cooling. When airflow is restricted, your system works harder, uses more energy, and struggles to maintain comfortable temperatures. Common airflow problems include dirty evaporator coils blocking heat exchange, clogged air filters restricting air movement, failed blower motors or capacitors, frozen evaporator coils from refrigerant or airflow issues, ductwork problems like disconnected or crushed sections, dirty blower wheels reducing air volume, and incorrect fan speed settings.
We perform comprehensive airflow diagnostics using manometers to measure static pressure, anemometers to verify air velocity at registers, temperature measurements across coils to verify heat exchange, and visual inspections of all airflow components. This thorough approach identifies restrictions and mechanical problems that simple visual inspection might miss. Airflow issues can also affect your home's air quality—explore our indoor air quality services for a healthier home.
As your air conditioner cools your home, it also removes humidity from the air. This moisture must be drained away properly to prevent water damage, musty odors, and system shutdowns. Common condensate problems include clogged drain lines from algae growth or debris, improperly pitched drain lines that don't drain by gravity, failed condensate pumps on systems with upward drainage, disconnected or damaged drain lines, and clogged drain pans.
Our condensate system service includes clearing clogged drain lines using appropriate methods, treating drain lines to prevent algae growth, testing and repairing condensate pumps, verifying proper drain line pitch and termination, inspecting and cleaning drain pans, and ensuring float switches and overflow protection work correctly. Proper condensate management prevents water damage and ensures your AC can remove humidity effectively.

When you call us for AC repair, we don't show up and start replacing parts hoping to stumble onto the solution. Instead, we follow a systematic diagnostic process refined over 40 years that identifies problems accurately before we recommend repairs. This approach saves you money by avoiding unnecessary parts replacement and ensures we fix the actual problem rather than just symptoms.
Our diagnostic process begins with gathering information from you about when the problem started, what symptoms you've observed, any unusual sounds or smells, and how the system behaves. We then perform a complete system inspection checking electrical components, refrigerant pressures and temperatures, airflow and filter condition, condensate drainage, thermostat operation and settings, and overall system cleanliness and condition.
Once we've identified your air conditioner's problem, we explain it in clear language without technical jargon and provide straightforward repair recommendations. We discuss what failed and why, what repairs are needed to fix it, cost estimates for the recommended repairs, and whether any underlying issues contributed to the failure. If your system has multiple problems or is showing signs of age-related wear, we'll prioritize repairs and help you understand which are urgent and which can be deferred.
For systems over 10–15 years old requiring major repairs, we honestly discuss repair versus replacement considerations. Sometimes investing in a significant repair makes perfect sense. Other times, replacing an aging system delivers better long-term value—including efficient alternatives like ductless mini-split systems. We provide the information you need to make an informed decision based on your circumstances, budget, and long-term plans.
When you approve repairs, we complete them using manufacturer-recommended procedures, quality replacement parts, and proper tools. We don't take shortcuts that might save a few minutes but compromise repair quality and longevity. Our approach includes using OEM parts when available or quality aftermarket alternatives, following proper refrigerant handling procedures, making secure electrical connections with proper wire sizing, testing all safety controls after repairs, verifying proper system operation under normal conditions, and cleaning up completely after work is finished.
