Frequently Asked Questions About HVAC Service in the GTA
Do you offer emergency heating and cooling repair in the Greater Toronto Area?
Yes. Aurora Star Tech Inc. is based in Vaughan, Ontario, and provides 24/7 emergency furnace and heating repair and air conditioning repair across the GTA. Call +1-647-657-2977 and we will book the earliest available visit.
Which brands do you install and service?
We are a Rinnai Pro certified contractor and an AirQuest authorized dealer, and we also service and install other major furnace, boiler, air conditioner and water heater brands. Browse our product catalog or request a quote for a specific model.
How often should I service my furnace or air conditioner?
Most manufacturers recommend a professional tune-up once a year: the furnace in the fall and the air conditioner in the spring. A yearly inspection keeps the system safe and efficient, and often catches small problems before they become emergency repairs.
Can you replace a water heater quickly?
In many cases, yes. We handle tank and tankless water heater repair and replacement, including time-sensitive replacements such as utility deadlines. Contact us with your current unit details and we will confirm availability.
What is a tankless water heater and is it worth it?
A tankless water heater heats water on demand instead of storing it in a tank, so it takes less space and does not run out of hot water during normal use. Whether it suits your home depends on your gas line, venting and household demand, which we check during a free quote visit.
Do you provide free quotes?
Yes. Send a quote request through our contact page or call us, and we will give you a clear price before work starts, with no surprise charges.
Which areas do you serve?
We are based in Vaughan and serve Vaughan, Toronto, Richmond Hill, Markham, Aurora, Newmarket, Mississauga, Brampton and the surrounding Greater Toronto Area.
Why does my furnace blow cold air or stop heating?
Common causes include a thermostat or signal problem, a dirty filter, an ignition or flame sensor fault, or a blocked vent. Replace the filter and check the thermostat first. If the problem continues, or if you smell gas, leave the home and call your gas utility, then contact a licensed technician.
