Why AC Tune Ups Matter
An AC tune-up is a comprehensive inspection, cleaning, and testing of your cooling system. Air conditioner manufacturers recommend annual tune-ups to keep systems running efficiently and reliably. Many air conditioner warranties require annual professional maintenance to stay valid. Aside from maintaining your warranty, regular maintenance will also:
- Extend your equipment’s lifespan.
- Help your AC operate more efficiently, saving you money and keeping you more comfortable.
- Help you avoid costly and inconvenient breakdowns.
If these benefits sound like something you’d like to experience for yourself, call us or contact us online.
What Our AC Tune Ups Include
During your appointment, a Deljo technician performs a start-to-finish service that combines careful inspection with precision adjustments. Before the steps outlined below, we’ll ask you about …
- Any hot/cold spots
- Unusual noises
- Recent repairs
Then we move through a detailed sequence that includes the following six steps.
System safety and controls
We verify thermostat operation, cycle the system from off → cool, and confirm all safety devices function correctly. We also inspect disconnects and electrical panels for wear or overheating.
Electrical and mechanical health
We tighten electrical connections, measure voltage and amperage draw, and test capacitors, contactors, and relays. We inspect the blower motor and fan for correct rotation and balance to prevent premature wear.
Airflow and filtration
Proper airflow and filtration go a long way towards superior comfort and efficiency. To evaluate this, we check static pressure (where applicable), check the blower wheel and housing, and inspect your air filter, replacing it if necessary.
Coil and condensate performance
We inspect and clean accessible condenser fins and check the evaporator coils’ condition. Then, we clear and treat the condensate drain to help prevent water leaks and clogs. This can dramatically improve system performance.
Refrigerant evaluation
We measure operating temperatures and pressures under load and compare them to specifications for your system type. If readings suggest a refrigerant issue, we’ll explain your options before performing any additional work.
Final performance test
We document supply/return temperatures, verify even cooling where zoning applies, and provide a written summary with recommendations so you know exactly how your system is performing today and what to plan for next.
Have a ductless mini-split or a zone control system? We offer AC tune-up services for those, too.
