Answers to Common Questions
View All FAQsWhat Is Included in a Typical AC Tune Up Service?
A typical AC tune-up includes cleaning, calibration, safety checks, and performance testing to keep your system efficient and reliable. Most problems we prevent start with dirty coils, low refrigerant, or loose electrical connections that strain parts and raise energy use. We tailor maintenance for Colorado conditions like dust and wildfire smoke that clog coils and filters.
- Clean indoor evaporator and outdoor condenser coils; clear debris around the unit.
- Check refrigerant level and verify superheat/subcooling; test start-up, run, and shutdown cycles.
- Inspect and tighten electrical components; measure motor amperage and verify safety controls.
- Flush the condensate drain and treat the pan to prevent clogs and odors.
Perks Club membership is $99/year and adds priority scheduling plus 20% off service. A small refrigerant undercharge can mimic a thermostat issue, so precise readings matter before replacing parts. Replace filters regularly and schedule maintenance before peak summer for fewer breakdowns. <br/> Updated: 2026-03-27 <br/> Need help in Louviers, CO? Call (720) 740-0350 or book online.
