Common questions
When's the best time of year for gas conversion in Ajax?
Late September through mid-November with Ajax averaging 95cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
Do you offer same-day gas conversion in Ajax?
Usually — call before 9am and we'll confirm a same-day arrival window inside Ajax for most standard scopes.
Is gas conversion covered by home insurance in Ajax?
Sudden damage (storm, animal, appliance failure) is usually covered minus deductible. Gradual wear generally isn't. A written pro assessment before the claim call materially improves outcomes.
Do you service condos and heritage homes in Ajax?
Yes. Condo boards in Ajax typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
What if it rains or snows on the booking day?
Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
How long does gas conversion take in Ajax?
1 day is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
