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?
Cooling emergencies jump the queue. Most days we reach London homes the same day you call, often within hours, and we stock the common parts so a central-air or ductless fix usually happens on the first visit.
What kinds of air conditioners do you repair?
Central air, ductless mini-splits, and high-efficiency units of every major brand. We diagnose the fault, replace failed parts like capacitors, fans, and compressors, and recharge refrigerant so your home cools properly again.
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 company. The same technicians service furnaces, heat pumps, thermostats, fireplaces, and ductwork, so one London number covers your home in every season.
How do I keep my AC from breaking down mid-summer?
A spring tune-up is the cheapest insurance there is. We clean the coils, check refrigerant and airflow, and catch worn parts before a 30-degree afternoon turns them into an emergency call.
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?
Every technician is fully licensed, insured, and trained on current cooling and heating equipment, so the work is done safely and to code from the first visit.
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.
