When to service air conditioner Ontario: Should I book AC service now or wait until next spring?
With hot, humid summers across the Greater Toronto Area (GTA), having a properly maintained AC unit before peak cooling demands hit is essential, and knowing exactly when to service your appliance can make a huge difference in terms of its overall performance levels, energy-efficiency rates, reliability, and your indoor comfort levels.
This guide goes over all you need to know about servicing your air conditioner before the summertime, so you can ensure that your unit is prepared to work optimally in your home, no matter how hot outdoor temperatures become.
When Should You Service Your Air Conditioner in Ontario?
The best time to book a service call for your home's air conditioning system is in the early spring, before outdoor temperatures begin to rise. By booking your annual appointment early on, you'll be able to have your cooling system inspected, cleaned, and tuned, before it's put under increased strain during the summer months. And, by planning ahead, you can avoid mid-summer breakdowns, and have peace of mind that your air conditioning unit is operating as efficiently as possible, so you can save money on your energy bills.
Best Time of Year to Service Your AC in Ontario
When it comes to having your air conditioner serviced, choosing the right appointment time can help you improve performance levels, reduce ongoing costs, and make scheduling a lot easier.
Spring AC Maintenance
-
Ideal timing: Ideally, homeowners across the Greater Toronto Area should aim to schedule their AC maintenance appointment in the early spring, between the months of March and May.
-
Prepare system before summer heat: Booking your AC maintenance appointment before the summer heat arrives can help ensure you've got a working unit ready to go at all times.
-
Lower service demand and better scheduling availability: By booking in the spring, when most HVAC companies are in the off-season, you'll be able to schedule your maintenance appointment without delay.
-
Early detection of issues before heavy use: Air conditioner maintenance is a great opportunity for technicians to identify any potential problems with your unit before they turn into costly repairs.
-
Improved energy efficiency before peak cooling season: Ensuring your AC system is clean and optimal will help it run more efficiently during the peak season.
Fall Maintenance and Off-Season Servicing
Fall maintenance appointments offers you another opportunity to keep your air conditioner in good working order following increased use. With a post-summer assessment, skilled technicians can identify wear and tear and prepare your HVAC system for the following year. That said, off-season maintenance is less urgent and won't replace the need to book another air conditioning service the following spring.
