FAQs
What is a precision tune-up for my air conditioner, and how is it different from a regular maintenance check?
A precision tune-up is a comprehensive, step-by-step service that goes beyond a quick filter change or visual inspection. Our certified technicians use calibrated instruments to measure critical operating data (refrigerant charge, superheat, sub-cool, static pressure, amperage draw, and temperature differentials) and then adjust the system back to manufacturer specifications. We also clean the evaporator and condenser coils, tighten electrical connections, lubricate moving parts, and test all safety controls. The goal is to restore your AC to peak efficiency and catch developing issues before they cause a breakdown—something that a basic maintenance visit rarely accomplishes.
How often should I schedule a precision tune-up for my AC unit in Delano’s climate?
In Delano’s hot, dry summers and cool winters, we recommend a precision tune-up once a year—ideally in early spring, before the heavy cooling season starts. Annual service is often a requirement to keep your manufacturer’s warranty intact, and it ensures that dust, agricultural debris, and hard-water mineral buildup common in the Central Valley don’t compromise efficiency. If your system is over 10 years old, runs nearly nonstop, or serves a household with pets and allergies, consider scheduling an additional mid-season check for optimal performance.
What specific tasks are included in your Delano precision tune-up service?
Our 26-point tune-up covers every performance and safety component of your air-conditioning system: • Record refrigerant pressures, superheat and sub-cool; adjust charge if needed • Deep-clean condenser and evaporator coils to improve heat transfer • Inspect blower wheel, clean if necessary, and balance blower motor • Check and tighten all electrical connections, relays, and contactors • Test capacitors, amperage draw, and voltage to prevent motor failure • Flush and treat condensate drain to eliminate algae and prevent water damage • Replace or clean standard air filter (high-MERV or media filters at additional cost) • Verify thermostat calibration and cycle system through all modes • Measure supply/return temperature split and static pressure to assess airflow • Lubricate bearings and moving parts, apply protective anti-corrosion spray • Provide a written health report with any recommendations before we leave.
Will a precision tune-up really lower my utility bills?
Yes. According to the U.S. Department of Energy, a dirty or poorly adjusted air conditioner can use 15–30 % more electricity than a properly maintained unit. By restoring correct refrigerant charge, maximizing airflow, and cleaning heat-exchange surfaces, a precision tune-up reduces the runtime needed to reach your set temperature. Many Delano homeowners see their summer electric bills drop by $10–$40 per month, which typically offsets the cost of the tune-up in a single season while extending the life of the equipment.
How long does the appointment take, and do I need to be home?
A standard residential precision tune-up takes about 60–90 minutes. We ask that an adult (18+) be present to provide access to the thermostat, indoor air handler/furnace, and outdoor condenser. If you can’t be home, you may authorize someone else or arrange access via a lockbox; just let our office know in advance. Our technicians wear protective shoe covers, use drop cloths, and text you an "on-the-way" notification with a photo ID for your peace of mind.
Can a tune-up help me avoid costly repairs or early replacement?
Absolutely. Roughly 80 % of major AC failures we see in Delano—compressor burnouts, blower motor seizures, and coil leaks—show early warning signs that are detectable during a tune-up. By spotting weak capacitors, minor refrigerant leaks, or restricted airflow early, we can recommend low-cost fixes (often under $150) that prevent four-figure repair bills later. Consistent documentation of tune-ups also supports any warranty claims and can add years to the overall lifespan of your system.
