Choosing the right air conditioning system ensures efficient cooling, humidity control, and long-term comfort.

Why AC Selection Matters

An improperly sized AC unit can increase energy bills and fail to cool your home effectively. Correct selection ensures optimal performance.

Benefits of a Guided AC Purchase

Consistent Cooling Performance

Correct sizing ensures steady temperature control without frequent on-and-off cycling.

Lower Energy Consumption

High SEER-rated units reduce electricity usage while maintaining strong cooling output.

Improved Indoor Air Quality

Modern AC systems help control humidity and support filtration systems for cleaner indoor air.

Longer Equipment Life

Balanced system operation reduces stress on compressors and internal components.

Our AC Selection Process

Step 1:

Cooling Load Calculation

We measure room size, insulation, and sun exposure to determine proper cooling capacity.

Step 2:

SEER Rating Comparison

We explain energy efficiency ratings to help you select the right system for long-term savings.

Step 3:

System Type Evaluation

We assess whether central air, ductless, or high-efficiency models are most suitable.

Step 4:

Budget Planning and Rebates

We review cost options and available rebate programs.

 Trustindex verifies that the original source of the review is Google. They installed the Rheem a/c and have been doing furnace and a/c maintenance annually. Quality service although we had “Ken” and “Simon”  and they were great and thorough. A few others weren’t so thorough. My rating is for the latest visit by Simon and explained what he did very well.

 Trustindex verifies that the original source of the review is Google. We’ve just replaced our furnace and thermostat and we are pleased with the installation process. The technician, Mohamed, arrived on time and finished the job as quickly as possible. He is very knowledgeable of the products he is installing. He took the time to answer our questions about the thermostat features since the “pro” ecobee is not clearly described online and “pro” means just that it is installed by contractors  and not that it’s the top of the line. Still it serves its purpose. I just wished this was explained to us when we got the quotation. Mohamed left the place clean and removed all the trash/ old furnace.

Dirty or Clogged Air Filter
This is the #1 reason for AC icing. When the filter is dirty:
- Airflow through the evaporator coil is reduced
- The coil gets too cold
- Moisture in the air freezes into ice
Solution: Replace the filter, turn the AC off for 5 hours, and then turn it on again.
Blocked or Closed Air Vents
If supply or return vents are blocked by furniture or closed:
- Air cannot circulate properly
- The evaporator coil temperature drops below freezing
- Ice forms on the coil
Solution: Make sure all vents are open and unobstructed.
Low Refrigerant Level
If the system has a refrigerant leak:
- Pressure in the system drops
- The coil temperature becomes too cold
- Ice forms
Signs of low refrigerant:
- AC runs continuously
- Weak cooling
- Hissing sound near lines
Solution: A service technician is required for diagnosis. Please contact our 24/7 service line: 416-335-0881
Furnace Blower Fan Problems
If the blower motor or capacitor is weak:
- Airflow across the evaporator coil decreases
- The coil freezes
Solution: A service technician is required for diagnosis. Please contact our 24/7 service line: 416-335-0881
