Common AC Problems: When to Repair vs. Replace
Knowing whether to repair your air conditioner or replace it entirely can prevent costly mistakes. Here’s how to tell when it’s time for expert air conditioning service, or a full system upgrade.
Signs You Need a New AC System
Inconsistent Cooling & Poor Airflow
If you’re constantly adjusting the thermostat or some rooms stay warm no matter what, your system might be the wrong size, or simply worn out. Upgrading to a properly sized and professionally installed AC can restore balance and comfort.
High Energy Bills
Old air conditioners lose efficiency over time. If you notice your cooling costs going up without any major lifestyle changes, your system may be working harder than it should, and costing you more than it’s worth.
Strange Noises or Odours
Sounds like grinding, rattling, or buzzing usually suggest failing components or loose hardware inside your unit. Meanwhile, musty or mildew-like smells often signal mould buildup within your AC, which can impact air quality and aggravate respiratory issues.
Fixable AC Issues with Air Conditioning Service & Repair
Thermostat Malfunctions
Your air conditioner may cycle on and off too frequently, fail to reach your desired temperature, or not start at all if the thermostat is failing. Often, this issue can be resolved with recalibration or a new thermostat installation, both quick and affordable fixes.
Refrigerant Leaks
Low refrigerant levels result in warm air blowing from your vents, and if left unchecked, can damage the compressor. Our technicians use safe, certified methods to locate the source of the leak, seal it properly, and recharge the refrigerant to restore system cooling.
Electrical or Sensor Issues
Wiring problems, tripped breakers, blown fuses, or failed sensors can all cause sudden AC failure or erratic cooling. These are usually straightforward to repair with proper tools and expertise, no need for a full system overhaul if addressed promptly.
If you’re unsure whether to proceed with repairs or replacement, our technicians will perform a full system evaluation and help you make the most cost-effective decision for your home and comfort goals.
What’s Included in Our Air Conditioning Services
Step 1: System Assessment and Customized Air Conditioning Solutions
Every service starts with a tailored assessment. We measure square footage, evaluate insulation, inspect ductwork, and determine system load requirements. Whether your project involves repairs or a complete system installation, we use this information to recommend the best solution based on your home’s unique layout and energy efficiency needs.
Step 2: Professional Installation & Reliable Repairs
For installations, we follow industry approved standards to improve airflow and extend the system’s lifespan. We use techniques like precise sizing and ductwork sealing to set up your AC for reliable cooling. If a repair is all you need, we quickly diagnose the issue and use manufacturer-approved parts to restore your system.
Step 3: Performance Testing & Optimization
Once the system is up and running, we measure airflow pressure, refrigerant behavior under load, output temperature variance, and static duct resistance. We don’t rely on guesswork, we use data to confirm the job was done right and that your system’s performance meets efficiency benchmarks.
Step 4: Ongoing Air Conditioning Service & Repair
The best way to avoid major AC issues? Stay ahead of them. Our follow-up care includes seasonal checkups, airflow balancing, and preventative part checks. With Mr. Furnace’s proactive servicing, your cooling system stays ready for whatever the next summer throws at it.

What Maintenance Does a New AC System Require?
To keep your air conditioner running at peak efficiency, a professional service visit once a year is essential, ideally in early spring. During this check-up, technicians inspect electrical components, test refrigerant pressure, and clean evaporator and condenser coils. At home, you should replace filters every 1-3 months, depending on usage, and clear away grass, leaves, and buildup from the outdoor unit.
How Much Does Air Conditioning Repair Cost?
The cost of repair depends on the issue. Quick fixes like replacing a capacitor or thermostat sensor are generally inexpensive. However, if your system is facing compressor failure, refrigerant loss, or motor issues, the cost will be higher. If your unit is past 10 years old and has been needing frequent service, our technicians can assess whether it makes more sense to invest in a new energy-efficient model.
