FAQs
What exactly is included in a Precision Tune-Up for heating and air conditioning in McDonald?
Our Precision Tune-Up is a 21-point inspection and adjustment service tailored to the climate in McDonald. It includes cleaning indoor and outdoor coils, calibrating the thermostat, testing safety controls, inspecting heat exchangers for cracks, measuring refrigerant charge, tightening electrical connections, lubricating moving parts, replacing the standard 1" filter, checking condensate drains, and verifying full system operation in both heating and cooling modes.
How often should I schedule a Precision Tune-Up for my HVAC system?
We recommend two tune-ups per year—once in spring for the air conditioner and once in fall for the furnace or heat pump. Seasonal tune-ups ensure peak efficiency before the heavy cooling and heating periods in McDonald’s variable climate, and they keep your manufacturer’s warranty valid.
What benefits can I expect from getting regular Precision Tune-Ups?
Regular tune-ups can lower energy bills by up to 15%, extend equipment life by several years, reduce the likelihood of emergency breakdowns, maintain manufacturer warranty coverage, and improve indoor air quality. Because McDonald experiences both hot, humid summers and cold winters, optimized performance translates directly into comfort and savings year-round.
Are Precision Tune-Ups still necessary if my HVAC system is new?
Yes. New systems still accumulate dust, vibration can loosen wiring, and refrigerant levels can drift during the first year of operation. Routine tune-ups protect your investment, document professional maintenance for warranty purposes, and ensure the system continues to deliver the efficiency promised on the rating label.
Do you service all HVAC brands and models during a Precision Tune-Up?
Absolutely. Our NATE-certified technicians are trained on every major HVAC brand—including Trane, Carrier, Lennox, Rheem, and Goodman—as well as ductless mini-splits and geothermal systems. We stock common replacement parts on our trucks, so most adjustments and minor repairs can be completed on the spot.
How much does a Precision Tune-Up cost in McDonald, and are there any discounts available?
A single Precision Tune-Up visit starts at $129. However, most homeowners enroll in our Comfort Club plan for $199 per year, which covers two seasonal tune-ups, priority scheduling, a 15% repair discount, and zero after-hours fees. Senior citizens, military personnel, and first responders receive an additional 10% off the standard pricing.
