FAQs

Frequently Asked Questions

Answers to the questions London homeowners ask us most.

Do you handle both heating and cooling, or just one?

Both. We are a full-service HVAC company, so the same team looks after your furnace in winter, your air conditioner in summer, and everything in between. One number covers your whole home comfort system.

Do you offer maintenance plans?

Yes. Seasonal maintenance is the core of what we do. A spring AC tune-up and a fall furnace check keep your system efficient, catch small problems early, and help your equipment last longer. Many of our customers stay with us year after year for exactly this.

How quickly can someone come out for a repair?

We aim to respond the same day and we prioritise loss of heat or cooling. Because we know our regular customers' systems, we often diagnose the issue faster too.

How do I know whether to repair or replace my furnace or AC?

We give you the honest math. We look at the age of the unit, repair history, efficiency, and what a replacement would actually save you, then lay out the options so you can decide. We will not push a new system you do not need.

Can you service the equipment I already have?

In almost all cases, yes. Our technicians work on every major brand of furnace, air conditioner, heat pump, and thermostat, including older and high-efficiency models, so you can keep the system you have running well.

Do you install heat pumps and ductless systems?

We do. Heat pumps and ductless mini-splits give you efficient heating and cooling from one system, and we help you choose, install, and maintain the right setup for your home and budget.

Can you help with air quality and ductwork too?

Yes. Beyond heating and cooling, we handle duct cleaning, ventilation, and smart thermostats, so your whole system works together for cleaner air and steadier comfort.

Are your technicians licensed and insured?

Every technician on our team is fully licensed, insured, and trained. You get professional, accountable work from people who treat your home with respect.

Do you serve areas outside of London, Ontario?

Yes. We serve London and nearby communities including St. Thomas, Strathroy, Dorchester, Komoka, and the surrounding area.

Do you offer 24/7 emergency service?

We do. Heating and cooling problems do not wait for business hours, so we are on call day and night, weekends and holidays included.
