Top 10 Signs Your Air Conditioner Needs Servicing

Alberta summers aren’t exactly tropical, but when the temperature climbs into the high 20s and beyond, you need a properly working air conditioner. A sudden heatwave can make your home feel stifling if your cooling system isn’t up to the task. If you don’t want it to come to this, call Hydro-Flo Plumbing & Heating at the first sign of trouble.

When to Schedule AC Repair

Here are 10 ways to tell you need professional air conditioner service as soon as possible.

1.      It’s Not Cooling Like It Used To

If your home feels warmer than it should, even with the system running, something’s wrong. Poor cooling may be caused by dirty coils, low refrigerant, or a worn-out compressor. The sooner a technician checks it out, the more likely they can perform a quick fix and get things back to normal.

2.      Weak or Uneven Airflow

Maybe the living room feels fine, but the bedrooms are stuffy. This could point to a clogged filter, blocked air ducts, or blower issues. Consistent airflow is a basic expectation from any central cooling system. If you’re not getting that, a home air conditioner servicing appointment should be next on your list.

3.      High Indoor Humidity

When the air conditioner runs, but the air still feels damp or sticky, you know something isn’t right. Your system should remove excess humidity from the air as it cools. If you’re left with that cool-but-clammy feeling, the problem could be low refrigerant, a clogged evaporator coil, restricted airflow, or simply an older unit that’s losing effectiveness. A professional tune-up can often restore proper humidity control.

4.      Strange Noises from the Unit

After years of relying on your air conditioner, you should know what it normally sounds like. If it starts clicking, banging, rattling, or whining, don’t ignore it. These noises often mean parts are coming loose or components are beginning to fail. It’s better to address the issue early than wait for something to break completely.

5.      Odd Smells Coming Through the Vents

A musty odour usually means mould is building up inside the system, which can affect indoor air quality. Then, a burning smell could indicate overheating wires or a problem with the motor. In either case, it’s best to shut off the system and contact an air conditioner cleaning service right away.

6.      Water Leaks or Pooling

Your air conditioner should never generate puddles. If moisture is collecting around the unit, you may have a blocked condensate drain, refrigerant leak, or broken pump. Moisture problems can damage your floors and lead to mould. That’s why fast, professional service matters.

7.      Higher Energy Bills with No Clear Cause

If you’ve noticed your energy bill climbing even though your usage habits haven’t changed, the air conditioner could be running inefficiently. Dirty components, leaking refrigerant, or a failing motor can force the system to work harder than necessary. Regular air conditioner servicing helps correct these inefficiencies.

8.      Frequent On-Off Cycling

Is your AC turning on and off every few minutes? This is called short cycling, which creates unnecessary wear and tear and prevents your home from reaching a stable temperature. Short cycling can be triggered by low refrigerant, electrical problems, or a poorly calibrated thermostat. An air conditioner service technician can sort things out and recommend the best repair.

9.      Ice or Frost on the Unit

Finding ice on the evaporator coil or refrigerant lines isn’t a good sign. Ice buildup typically points to poor airflow or low refrigerant levels. Ignoring it risks damage to the compressor, one of your system’s most vital and expensive components. Prompt service is the best way to prevent this.

10.  The Thermostat Doesn’t Match the Room Temperature

If your thermostat says it’s 22 degrees C, but you swear it feels closer to 28, something’s off. It might be a sensor problem or the thermostat itself may be faulty. These issues are usually simple to resolve during a routine air conditioner servicing visit.

When to Repair vs. Replace Your Air Conditioner

Sometimes, a simple fix is all you need. Other times, continuing to pour money into an aging or unreliable system no longer makes sense. Here’s how to decide which path is right for your home.

When Repair Makes Sense

• Your system is under 10 years old and has been regularly maintained.
• You’re dealing with a single issue like a clogged drain line or a minor refrigerant leak.
• The repair cost is less than half of the replacement cost.
• Your energy bills have been stable and your comfort level good until this problem arose.
• You plan to move soon and can’t justify replacing the system.

When Replacement Is the Smarter Option

• The unit is over 12 years old.
• You’ve had two or more repairs in the past year, and costs are adding up.
• The compressor or condenser coil has failed.
• The system uses R-22 refrigerant, which has been phased out and is increasingly hard to source.
• Repairing the system would be nearly as expensive as buying a new unit.
• Your energy bills are consistently high, and your home still doesn’t feel cool.
• Your current system doesn’t match the size of your home, possibly due to a recent addition.
• You’re considering selling your home, and buyers expect a newer HVAC system.
