FAQs
What is a precision tune-up for my HVAC system?
A precision tune-up is a scheduled preventative-maintenance visit during which a certified technician thoroughly inspects, cleans, tests, and calibrates every critical component of your heating and air-conditioning equipment. The goal is to restore the system to factory-fresh performance, prevent unexpected breakdowns, and verify that safety controls, refrigerant levels, and airflow are all within manufacturer specifications.
Why are annual precision tune-ups important in Winfield’s climate?
Winfield sees hot, humid summers and chilly winters, so both your air conditioner and furnace work hard for much of the year. Annual tune-ups catch wear-and-tear before it becomes a costly outage, maintain peak efficiency despite our temperature swings, and keep warranty coverage intact. Regular service also assures safe operation by checking for carbon-monoxide leaks in the heating season and proper refrigerant pressures in cooling season.
What services are included in your precision tune-up visit?
Our 21-point tune-up includes: (1) cleaning condenser and evaporator coils, (2) testing thermostat accuracy, (3) checking refrigerant charge and topping off if needed, (4) inspecting blower motor amperage, (5) tightening electrical connections, (6) lubricating moving parts, (7) flushing the condensate drain, (8) replacing or cleaning the air filter, (9) verifying proper airflow and static pressure, (10) testing safety controls and ignition sequence, (11) measuring temperature differential, and several other mechanical and safety checks. You receive a written report with all readings and recommended repairs, if any.
How long does a tune-up take and will it disrupt my day?
Most residential tune-ups take 60–90 minutes per system. You don’t have to be home the entire time, only to let the technician in and review findings at the end. Our technicians use protective shoe covers and drop cloths to keep your home clean, and power is interrupted only for a few minutes while electrical tests are performed.
Will a precision tune-up really lower my energy bills?
Yes. Dirty coils, improper refrigerant charge, and loose electrical connections all force equipment to run longer and harder. Studies by the U.S. Department of Energy show that a properly maintained HVAC system can operate up to 25% more efficiently than a neglected one. Customers typically see energy-cost savings that offset the price of the tune-up within the first cooling or heating season.
