FAQs
Frequently Asked Questions
Answers to the questions London homeowners ask us most.
My AC died in a heat wave. How fast can you get here?
Fast. No-cool calls go to the front of the queue, and we aim for a same-day visit across London and Middlesex County. We answer the phone ourselves and treat a dead air conditioner in a heat wave as the emergency it is.
What kinds of air conditioners do you repair?
All of them. We service central air conditioners, ductless mini-splits, and heat pumps from every major brand, handling refrigerant issues, compressor and capacitor failures, frozen coils, electrical faults, and airflow problems.
Is it worth repairing my old AC or should I replace it?
If your unit is under about ten years old and the fix is straightforward, a repair is almost always the smarter spend. We give you the honest numbers on both options and never push a replacement you don't need.
Would a ductless mini-split cool my home better?
For rooms a central system struggles to reach, or homes with no ductwork at all, a ductless mini-split delivers quiet, zone-by-zone cooling and trims your summer energy bills. We size and install them to match your space.
Do you only handle cooling, or full HVAC?
Cooling is our specialty, but we are a full HVAC team. That means we also repair and service furnaces, heat pumps, ductless systems, and thermostats, so the same crew looks after your home in January as well as July.
How do I keep my AC from breaking down mid-summer?
A spring tune-up catches most of it. We clean the coils, check refrigerant, clear the condensate drain, and swap the filter so the unit is not working overtime on the hottest day. Booking service before the season starts is the single biggest thing you can do.
Can you swap in a smart thermostat with my AC work?
Yes. We install and set up programmable and smart thermostats while we're already on site, dialing in your cooling schedule so the system runs efficiently and you stay comfortable.
Are your technicians licensed and insured?
Yes. Every technician on our team is fully licensed, insured, and trained on residential cooling equipment. You get professional, accountable work from people who respect your home and explain what they are doing.
Do you serve areas outside of London, Ontario?
Yes. We serve London and nearby communities including St. Thomas, Strathroy, Dorchester, Komoka, and the surrounding Middlesex County area.
Do you offer 24/7 emergency service?
We do. A house that won't cool in summer or won't heat in winter can't wait for business hours, so we take emergency calls any time, day or night.
