Question 1

When should I switch from AC to heat?

Accepted Answer

Great timing question for Ottawa homeowners! The short answer is: switch to heat when overnight temperatures consistently drop below 15°C (59°F), which in Ottawa typically happens in late September to early October.

There's no single magic date, but your comfort is the best guide. Most people find they need heating when daytime highs stay below 18°C and nights dip into single digits. Ottawa's climate can be unpredictable in the shoulder seasons — you might need heat one week and AC the next in

Question 2

When should I turn on my AC in Ottawa?

Accepted Answer

In Ottawa, you can typically start using your air conditioning when daytime temperatures consistently reach 20-22°C (68-72°F) and nighttime temperatures stay above 15°C (59°F). This usually happens in late May or early June, though Ottawa's unpredictable spring weather means some years you might need it as early as mid-May or not until mid-June.

The key is watching for sustained warm weather rather than just a single hot day. Ottawa's spring can swing from 25°C one day to 10°C the next, so resi

Question 3

Should I run my fan continuously in summer?

Accepted Answer

Running your fan continuously in summer can provide better air circulation and comfort, but it comes with trade-offs in energy costs and filter replacement frequency. The decision depends on your specific comfort needs, home layout, and energy priorities.

Continuous fan operation helps eliminate hot and cold spots throughout your home by constantly circulating air. This is particularly beneficial in Ottawa's humid summers, as moving air feels cooler on your skin and helps maintain more consiste

Question 4

How do I keep my house cool without AC?

Accepted Answer

There are several effective ways to keep your house cool without air conditioning, especially during Ottawa's hot summer days. The key is using a combination of ventilation, shading, and heat reduction strategies.

Natural ventilation is your best friend for cooling without AC. Open windows on opposite sides of your home to create cross-ventilation, allowing hot air to escape and cooler air to flow through. Use this strategy during cooler evening and early morning hours when outdoor temperatures

Question 5

When is the best time to buy a new furnace?

Accepted Answer

The best time to buy a new furnace is during the shoulder seasons - late spring through early fall - when demand is lower and you can take advantage of better pricing and scheduling flexibility.

Spring and summer offer the biggest advantages for furnace replacement. HVAC contractors are less busy during these months, which means you'll get better availability for installation dates, more time for the technician to do quality work, and often better pricing. Many manufacturers also offer rebates

Question 6

What temperature should I keep my house when on vacation in winter?

Accepted Answer

Set your thermostat to 15-18°C (59-64°F) when away during Ottawa winters. This temperature prevents freezing while significantly reducing your heating costs compared to normal living temperatures.

Why this temperature range matters: Keeping your home too cold (below 15°C) risks frozen pipes, especially in older Ottawa homes where plumbing may run through exterior walls or unheated basements. Water pipes typically freeze around 0°C, but the temperature inside walls and near exterior plumbing can

Question 7

How do I prepare my HVAC for winter in Ottawa?

Accepted Answer

Start preparing your HVAC system for Ottawa's harsh winters in early fall - ideally by October - to ensure reliable heating when temperatures drop below -20°C. The key steps include furnace maintenance, filter changes, and system testing before you actually need the heat.

Schedule a professional furnace tune-up with a licensed HVAC technician before the heating season begins. This service typically costs $150-$200 in Ottawa and includes cleaning the heat exchanger, checking gas connections, tes

Question 8

What is the best temperature for sleeping in winter?

Accepted Answer

The ideal bedroom temperature for winter sleeping is between 60-67°F (15.5-19.5°C), with most sleep experts recommending around 65°F (18°C) for optimal rest.

Your body naturally drops its core temperature as you prepare for sleep, and a cooler room helps facilitate this process. When your bedroom is too warm, it can interfere with your body's natural temperature regulation and lead to restless, interrupted sleep. The 60-67°F range allows your body to cool down properly while still maintaining c
