This easy guide explains how to spot common AC problems, try quick fixes, and decide whether to book an air conditioner repair or invest in a new air conditioner installation.
1. Quick Checks Before You Call a Pro
| DIY Step | What to Do | Why It Matters |
|---|---|---|
| Thermostat | Confirm it’s set to Cool and below the current room temperature. Replace batteries if needed. | Prevents an unnecessary service call. |
| Air Filter | Remove and inspect. If it’s dirty, replace it. | A clogged filter causes poor airflow and frozen coils. |
| Breaker Panel | Make sure the AC breaker is ON and hasn’t tripped. | Restores power in seconds. |
| Outdoor Unit | Clear debris and maintain ≈ 60 cm of space around the condenser. | Improves airflow and efficiency. |
| Supply Vents | Open all vents and remove obstructions (rugs, furniture). | Balances temperatures throughout the house. |
Pro Tip: After these steps, run the system for 10 minutes. Still warm air? Move on to Section 2.
2. Warning Signs You Shouldn’t Ignore
- Strange Odors
- Burning smell: Potential electrical issue.
- Musty smell: Possible mold in ducts or evaporator coil.
- Unusual Noises
- Grinding: Worn bearings.
- Hissing: Refrigerant leak (needs a professional technician for diagnostic and repairs).
- Short Cycling
- The system turns on/off every few minutes—often due to thermostat placement, refrigerant issues, or oversized equipment.
- Rising Energy Bills
- If costs climb but usage stays the same, an inefficient AC or duct leak could be to blame.
When you notice any of these, call your Atlantis HVAC professionals for HVAC service in Oakville and surrounding areas.
Repair vs. Replace—Which Is Best?
| Factor | Choose Repair When… | Choose Replacement When… |
|---|---|---|
| Age | Unit is under 10 years. | Unit is 12–15 years or older. |
| Repair Cost | Under 30% of new-system price. | Over 40% of new-system price. |
| Efficiency (SEER) | Bills are stable and comfort is good. | High bills or very low SEER rating. |
| Breakdowns | Rare. | Frequent calls each season. |
Rule of Thumb: Repair Cost × Unit Age.
If that number is higher than a new unit’s price, replacement makes sense.
Why Replacement Sometimes Wins
- Home additions demand more cooling capacity.
- You may be pairing upgrades with a furnace installation in Oakville and surrounding areas for whole-home efficiency.
- New systems offer smart thermostats and lower energy bills.
If replacement is on the table, spring or early fall offers better scheduling and potential discounts from HVAC companies in Oakville and surrounding areas.
