When your air conditioner stops working during a hot Saskatoon summer, comfort can disappear fast. Whether your system is blowing warm air, making strange noises, or not turning on at all, understanding what’s going wrong — and when to call a professional — can save you time, money, and stress.

At MNS Ltd. Mechanical Contractors, we provide trusted AC repair in Saskatoon for residential and commercial properties. Below, we break down the most common air conditioning problems, typical repair costs, and the signs it’s time to call a licensed HVAC professional.

Common Air Conditioning Problems in Saskatoon Homes

1. AC Blowing Warm Air

This is one of the most frequent service calls we receive.

Possible causes:

• Low refrigerant levels
• Dirty condenser coils
• Thermostat issues
• Electrical or compressor problems

In Saskatoon’s dry summer heat, systems often work harder, which can expose hidden issues quickly.

2. Weak or Poor Airflow

If some rooms feel cooler than others, airflow could be restricted.

Common reasons include:

• Clogged or dirty air filters
• Blocked vents or duct issues
• Failing blower motor

Poor airflow reduces efficiency and can cause your system to overwork, leading to higher energy bills.

3. AC Unit Freezing Up

Ice buildup on your AC unit may seem odd in summer, but it’s a clear warning sign.

Typical causes:

• Restricted airflow
• Low refrigerant
• Dirty evaporator coils

Ignoring a frozen unit can lead to compressor damage — one of the most expensive AC repairs.

4. Strange Noises or Odours

Grinding, squealing, or rattling noises are not normal.

Unusual smells may indicate:

• Electrical problems
• Mold growth in the system
• Overheating components

If your AC sounds or smells “off,” it’s best to shut it down and call a professional.

5. AC Won’t Turn On

If your system won’t start at all, the issue may be:

• A tripped breaker
• Faulty thermostat
• Electrical or control board failure

A licensed HVAC technician can safely diagnose and resolve the issue.

How Much Does AC Repair Cost in Saskatoon?

AC repair costs vary depending on the issue, system type, and parts required.

Typical AC repair ranges in Saskatoon:

• Minor repairs: $150 – $350
• Electrical or refrigerant issues: $350 – $800
• Major component replacement: $800+

Regular maintenance can help prevent many of these issues and extend the life of your system.

When Should You Call a Professional for AC Repair?

You should call a certified HVAC professional if:

• Your AC is blowing warm air
• Cooling is inconsistent throughout the house
• You hear loud or unusual noises
• Ice forms on the unit
• Your energy bills suddenly spike
• The system won’t turn on at all

Delaying repairs can turn a small issue into a costly breakdown.
