Frequently asked Questions

Are there rebates for heating and cooling services?

Yes, some government and utility companies offer rebates for energy-efficient heating and cooling systems, including heat pumps, water heaters and other HVAC equipment. Check with your local utility or visit our promos page for the latest offers.

Do you offer financing?

Yes, we offer flexible financing options to make upgrading your equipment affordable. Contact us to learn about payment plans and special offers available for new installations.

What guarantee do you offer on your repairs and installs?

We provide a guarantee on all repairs and installations, ensuring peace of mind and reliable service. Warranty and guarantee depends on the service or equipment.

Should I repair or replace my AC?

The answer often depends on how old it is. If your AC is about 15 years old, you should start planning to replace it anyway. The good news is that they are a lot more efficient these days, so replacing an old AC can mean a lot less money going to electricity every month. Considering that Ontario has the fastest rising electricity rates in North America, it can make a difference. If your air conditioner is on its last legs, (e.g. a failed or noisy compressor, leaking coil, or other issues) it makes more financial sense to buy a new one. In the end it will depend on the cost of the repair VS the cost of replacement (minus the energy savings and any rebates you can get).

Should I repair or replace my furnace?

Consider replacing your furnace if it’s over 15 years old, needs frequent repairs, or has become inefficient. A technician can assess whether repair or replacement is the better option.

Why is HVAC maintenance important?

Regular maintenance ensures efficiency, extends equipment life, and prevents costly repairs by identifying issues early.

What payment methods do you accept?

We accept a variety of payment methods, including major credit cards (Visa and MasterCard), debit cards, and cash. Flexible financing options are also available for larger purchases.
