What Is an Air Conditioner Tune-Up?
An A/C tune-up is preventative maintenance designed to keep your cooling system running efficiently and reliably — before the summer heat puts it to the test. Think of it like a seasonal checkup: regular servicing extends the life of your equipment, helps maintain manufacturer warranty requirements, and ensures your home stays comfortable when you need it most.
When you book a tune-up with Markham Heating and Air Conditioning, a fully licensed technician will perform a thorough inspection of your system — checking that your A/C is cooling and circulating air properly, and doing so safely and efficiently. We service all major air conditioner brands.
Here are a few items covered in our 18-point inspection:
| Inspection Item | Why It Matters |
|---|---|
| Thermostat operation | Confirms your system responds correctly and cools to the right temperature |
| Air filter inspection & cleaning | A dirty filter restricts airflow and is one of the leading causes of A/C inefficiency and breakdowns |
| Refrigerant level check | Low refrigerant causes poor cooling, ice buildup, and long-term compressor damage |
| Condenser coil inspection & cleaning | Dirty coils force the system to work harder, driving up energy costs and wear |
| Electrical connections & wiring check | Loose or corroded connections are a common cause of system failures and safety hazards |
| Capacitor & contactor inspection | These components start and run your compressor — worn ones are a leading cause of A/C breakdowns |
| Blower motor & airflow check | Ensures cool air is being distributed properly throughout your home |
A full written report of our findings is available on request after every tune-up, so you always know exactly where your equipment stands.
Why it matters
Regular tune-ups help catch worn parts before they fail, keep your air conditioner running efficiently, and protect your home from carbon monoxide risks. Annual maintenance may also be required to keep your equipment warranty valid.
