Question 1

How often should I service my furnace?

Accepted Answer

We recommend a full maintenance visit once a year, ideally before heating season starts. Regular tune-ups catch small issues early, keep your system running efficiently, and help avoid a breakdown on the coldest night of the year.

Question 2

How do I know if I need a repair or a full furnace replacement?

Accepted Answer

If your furnace is over 15 years old, needs frequent repairs, heats unevenly, or your energy bills keep climbing, replacement is usually the more cost-effective option. Younger systems with a single issue are almost always worth repairing — we'll always give you an honest recommendation either way.

Question 3

Should I choose a tankless or a tank water heater?

Accepted Answer

Tankless units like Rinnai give you continuous hot water and a smaller footprint, and tend to be more energy efficient over time. Tank water heaters have a lower upfront cost and are a solid choice for smaller households. We'll walk through both options based on your home and hot water usage.

Question 4

Do you offer emergency HVAC repair in Ottawa?

Accepted Answer

Yes — a broken furnace or AC doesn't wait for business hours, and neither do we. Thermoza offers 24/7 emergency repair across Ottawa with the same upfront, fair pricing we use for scheduled work.

Question 5

What areas do you serve?

Accepted Answer

We serve Ottawa and the surrounding communities, including Nepean, Barrhaven, Kanata, and Orléans. If you're just outside these areas, give us a call — we're happy to check.

Question 6

Are your installations covered by warranty?

Accepted Answer

Yes. Thermoza is licensed and insured, and every installation we complete is backed by a workmanship warranty in addition to the manufacturer's equipment warranty.

Question 7

How much does a new furnace or AC installation cost?

Accepted Answer

Installations start from $500, but the exact price depends on your home's size, existing ductwork, and the equipment you choose. We provide a free in-home assessment so you get one clear, upfront number before any work begins.

Question 8

Can a new high-efficiency system qualify for rebates?

Accepted Answer

Many high-efficiency furnaces, heat pumps, and water heaters can qualify for local energy rebate programs. We'll help you identify equipment that may be eligible as part of your free quote — just ask.
