FAQs
What exactly is a precision tune-up for my heating and air-conditioning system?
A precision tune-up is a comprehensive preventative-maintenance visit performed by a certified HVAC technician. During the appointment we inspect, clean, calibrate and test every critical component in both your furnace/heat pump and air-conditioning system. The goal is to restore the equipment to peak operating condition, improve safety, reduce energy consumption and identify small issues before they turn into major repairs.
How often should I schedule a precision tune-up in Cowan’s climate?
Because Cowan experiences hot, humid summers and cool, occasionally frosty winters, we recommend two tune-ups per year—one in early spring for the A/C or heat-pump cooling mode and one in early fall for the furnace or heat-pump heating mode. Bi-annual service keeps each side of the system ready for the season ahead and satisfies most manufacturer maintenance requirements.
What specific tasks are included in your HVAC precision tune-up?
Our checklist includes: • Measuring refrigerant levels and superheat/subcool to verify proper charge • Cleaning the outdoor condenser coil and indoor evaporator coil • Inspecting and tightening all electrical connections • Testing capacitors, contactors and relays • Lubricating motors and bearings where applicable • Checking blower wheel balance and cleaning the blower compartment • Replacing or washing the air filter (customer-supplied if specialty size) • Verifying thermostat calibration and cycling system • Inspecting heat exchanger for cracks and running a combustion analysis on gas furnaces • Flushing the condensate drain, adding algae treatment tablets • Measuring temperature split and static pressure • Documenting results and explaining any recommended repairs.
How can a precision tune-up save me energy and money?
The EPA reports that a well-maintained HVAC system can operate up to 15% more efficiently than a neglected one. Clean coils and correct refrigerant charge improve heat transfer, while a properly adjusted gas furnace burns less fuel. Fewer breakdowns mean lower repair costs, and catching failing parts early eliminates emergency-service premiums. Customers in Cowan typically recover the tune-up investment through reduced utility bills within one cooling and one heating season.
Will a precision tune-up help maintain my factory warranty?
Yes. Most HVAC manufacturers—including Trane, Lennox, Carrier and Goodman—state in their warranty documents that proof of annual professional maintenance is required to keep parts coverage valid. Our tune-up includes digital inspection records and an invoice you can present if warranty service is ever needed, giving you peace of mind that your warranty remains intact.
How long does the service take, and do I need to be home?
A typical single-system precision tune-up takes 60–90 minutes; dual fuel or multi-zone systems may run two hours. We prefer that an adult be present so we can review findings and get authorization for any minor adjustments. If your schedule is tight, we can perform outdoor work independently and arrange a quick phone or video summary, then schedule a brief indoor visit for thermostat and filter tasks at your convenience.
