What Happens During an Air Conditioner Repair?
Table of Contents
Calling for air conditioner repair can feel like calling in the unknown. What exactly will the technician do? Will it be expensive? Will it even fix the issue?
At HVAC Zack, we believe in transparency. Whether your system is blowing hot air or making strange noises, knowing what to expect during a service call can make the whole experience less stressful—and help you make informed decisions about your home comfort.
Here’s what actually happens when you call HVAC Zack for AC repair.
1. The Pre-Visit Check-In
When you call or book online, we’ll ask a few quick questions:
What’s the issue you’re noticing?
How old is your unit?
Has it been serviced recently?
This helps us prepare for your visit with the right tools, parts, and time. It also lets us know if you’re working with a central air conditioner or a ductless mini-split.
2. On-Site Diagnosis: Tools and Know-How
Once we arrive, the real detective work begins. We start by inspecting the entire cooling system—from your thermostat to the outdoor condenser.
Here’s what we’re checking:
Thermostat function
Airflow strength at the vents
Refrigerant levels
Electrical connections
Condition of coils and filters
Any strange sounds or odours
This process helps us identify whether you’ve got a minor issue (like a clogged filter) or something more serious (like a failing capacitor or refrigerant leak). For a list of early warning signs, check out our post on when to call for AC repair.
3. The Repair: From Simple Fixes to System-Savers
Depending on what we find, we’ll move into one of the most common types of repairs:
| Repair Type | Typical Fix | Time Estimate |
|---|---|---|
| Dirty or clogged filter | Replace or clean the filter | 10–15 mins |
| Low refrigerant | Locate and seal leak, recharge system | 1–2 hours |
| Faulty capacitor or relay | Replace faulty components | 30–60 mins |
| Frozen evaporator coil | Thaw and diagnose root cause | 1–2 hours |
| Drainage issue | Clear condensate line or drain pan | 30–45 mins |
We carry most parts with us, but if something specialized is needed, we’ll explain next steps clearly.

4. Communication Every Step of the Way
You’ll never be left guessing. Once we’ve diagnosed the issue, we explain:
What’s wrong
What needs to be fixed
What it will cost
How long it will take
No pressure. No upsells. Just honest advice.
5. Post-Repair Run-Through
Once the fix is done, we’ll test your system thoroughly:
Is it cooling evenly?
Is airflow strong?
Is the thermostat cycling properly?
We’ll also give you tips on keeping things running smoothly—like changing your filters regularly or scheduling seasonal maintenance.
6. Bonus: When Repairs Aren’t the Right Call
Sometimes, a repair just isn’t worth it—especially on older units. If the cost of the fix approaches half the cost of a new system, we’ll walk you through your options for a new air conditioning install.
You’ll always have the final say—and we’re here to help either way.
