Professional HVAC Contractors in Scarborough, ON

All cooling systems are rated by the seasonal energy efficiency ratio (SEER). Many older systems now in use have SEER of 6 or below. By 1994 the average SEER for all units shipped in North America improved to 13 SEER. The higher the rating, the more efficient the system.

In most cases, definitely not. Cooling systems are more complicated to service and usually require expert attention in order to comply with federal regulations, such as the Clean Air Act that prohibits releasing refrigerants into the atmosphere. Contact your installer or licensed service technician at the first sign of trouble for professional AC repair.

The main thing is to have the system checked each year before the peak-cooling season by a qualified AC service technician. Then, remember to keep the air filter clean and the outdoor unit free of leaves and debris.

Check it at least every month during peak use and replace it when it looks dirty enough to significantly impair the airflow through it. Some filters, such as media filters or electronic air cleaners, are washable; others are disposable and must be replaced.

If you want flexibility to control your temperature changes, a digital programmable thermostat utilizing features like remote access, and geo-fencing will probably be best. A manually operated system will require you to change the temperature setting whenever you want to change the temperature.
