Cooling Repairs
Common Air Conditioning Problems We Repair
We diagnose and repair the full range of residential and commercial air conditioning failures. Most of them trace back to a handful of common faults, and once we know which one we are dealing with, we can usually fix it on the same visit.
When your system blows warm air, short cycles, or refuses to start, the discomfort is immediate, and a struggling unit quietly drives up your energy bills as it works harder to reach the temperature you set. A frozen evaporator coil or a refrigerant leak makes both problems worse.
Some failures need immediate attention. Running a system that is low on refrigerant or has a failing compressor can turn a manageable repair into a full system replacement. Our technicians carry diagnostic tools to find the root cause on the first visit, so you are not paying for guesswork.
We service both central air systems and ductless mini-splits, and we work on all major brands including LG, Navien, Continental, and Napoleon, plus budget alternatives. Once the faulty component is identified, most repairs are completed in a single visit.

The Process
Our Air Conditioning Repair Process
Our repair process is straightforward: call us, we diagnose the issue, and we fix it right.
-
-
On-site diagnosis
Your technician inspects the system, tests the components, and identifies the failure point. We check refrigerant pressure, electrical parts, the compressor, and airflow instead of guessing at the cause.
-
Transparent estimate
Before any work begins, we explain what is wrong, what needs to be repaired or replaced, and what it will cost. You get upfront pricing and the final say. No surprises on the bill.
-
Repair completion
Once you approve the estimate, we complete the repair, test the system to confirm it is cooling properly, and clean up the work area before we leave.
-
System walkthrough
We show you what we fixed and answer any questions about operating the system or keeping it running well, so you understand your own equipment.
Most repairs are completed in a single visit. If a part needs to be ordered, we schedule a follow-up promptly and get your cooling back as soon as it arrives. We service systems across Timmins, South Porcupine, Schumacher, Cochrane, Kapuskasing, and Kirkland Lake, and surrounding communities within a 300 km radius.

We carry common replacement parts for the brands we install, which keeps wait times short when a repair calls for one.
Repair or Replace
When to Repair vs Replace Your AC
Not every failing air conditioner needs to be replaced, but some do. Here is how to decide.
Repair makes sense when
- The system is less than 10 years old
- The repair costs less than half the price of a new system
- The unit has been well maintained
- It uses R-410A refrigerant, not the older R-22
- The compressor is still in good condition
Replacement makes sense when
- The system is 12 or more years old
- Repair costs approach half of replacement cost or more
- The unit still runs on obsolete R-22 refrigerant
- The compressor has failed
- You are facing frequent breakdowns
Efficiency is part of the math. Older systems typically run at 10 to 13 SEER, while modern units run at 16 SEER and above. A more efficient system can cut cooling costs noticeably over a season, which helps offset the cost of replacing a unit that is near the end of its life.
We give honest recommendations. We will tell you when a repair is the smart choice and when replacement makes more financial sense. Because we offer both repair and full system installation, we have no incentive to push you toward a new system you do not need. If replacement is the better path, our air conditioning installation services cover sizing, efficiency options, and timelines.

Efficiency + Sizing
Understanding AC Efficiency and Sizing
Air conditioning efficiency and proper sizing directly affect your comfort and your energy bills. Two numbers do most of the work in understanding your system: SEER and BTU.
SEER, the Seasonal Energy Efficiency Ratio, measures cooling output against energy input over a typical cooling season. Higher SEER means lower operating costs. Modern systems range from 14 SEER at the minimum to 20+ SEER for high-efficiency models, while older systems often run at 10 to 13 SEER.
BTU, the British Thermal Unit, measures cooling capacity. A typical home needs roughly 20 to 25 BTU per square foot, adjusted for insulation, window area, and climate. Sizing matters in both directions. An oversized AC short cycles and fails to remove humidity, while an undersized one runs constantly and cannot keep up on the hottest days.
Timmins weather, with cold winters and warm summers, calls for systems that handle seasonal extremes. Our technicians assess sizing during repairs and will tell you if your current system is mismatched to your space. For year-round heating and cooling in a single system, a cold-climate heat pump installation is worth considering.
