Purchasing a brand new furnace is a serious decision these days because there are so many options, including different brands, models, and variations, technical capabilities, furnace types, and efficiency ratings. However, one of the most important factors to consider when choosing a new furnace is the size that is best suitable for your home in Newmarket.

A Building Permit from Newmarket Town Government is usually not required for furnace replacement if no building alterations are taking place.

Installing a properly sized furnace requires more than simply calculating your home’s square footage. There are various aspects to consider while sizing a new gas furnace. Now we’ll go over what those factors are, why properly sizing a furnace is so important, and how to find a furnace that’s the right size for your location, environment, and comfort needs.

The goal of this article is to guide you in choosing the required size of furnace for your heating needs. It is calculated by taking the required heating BTU per square foot for most homes and your climate zone. Our heating BTU calculator takes these critical things into consideration, allowing you to give an answer for common questions as “how many BTUs to heat a home?” or “What size furnace do I need?”

The BTU per square foot heating rule of thumb varies greatly depending on your climate and the area of your house or room you wish to heat up. Newmarket is located in Zone 2.

Why choosing the best Furnace Size Is So Important?

While it may be appealing to choose a smaller furnace to save money on the purchase or a larger furnace to increase space-heating, we should follow the Golden Mean rule with furnaces, just as we should with many aspects in our lives: you need one that is just right for your home.

A furnace which is far too powerful will cycle irregularly. This is problematic because it will generate hot and cold zones around the house, decrease efficiency, require additional maintenance, and shorten the life of the furnace.

An undersized furnace will operate non-stop and won’t keep the temperature in your home at comfortable levels. The additional workload will also increase your energy bills, inrease the probability of maintenance issues, and also shorten the lifespan of your heating unit.

Another drawback of having a furnace that is the incorrectly sized is that it will reduce the overall efficiency of your heating system.
The AFUE (Annual Fuel Utilization Efficiency) is the thermal efficiency measurement of a furnace based on normal operation. The AFUE tries to represent the equipment’s actual, season-long average efficiency, taking into account all operating factors.

You won’t be able to get the efficiency rating you paid for if your furnace runs continuously or irregularly because it is the wrong size. That means more energy use and higher heating expenses.

Your furnace must be correctly sized for your home in order to perform at the efficiency level it is rated for.

How many BTU do I need for my house in Newmarket?

That is a crucial question that must be answered correctly. On the coldest winter days, a furnace that is way too undersized will not heat your home properly. Areas further away from the furnace may become uncomfortably cold in your home.

An oversized furnace will waste large amounts of energy, and create hot patches around vents close to the furnace before the heating cycle stops.

When you talk about furnace size, you are not talking about the actual physical dimensions of the unit. Rather, the size of a furnace is determined by its heating output and the amount of heat it can provide.

The output of a furnace is often measured in British thermal units (BTU) per hour. A BTU is a unit of measurement for energy, particularly the amount of energy necessary to raise the temperature of one pound of water by one degree Fahrenheit. Heat is now understood to be the same as energy. The joule (J) is the current SI unit for heat and energy; one BTU equals about 1055 J.

Furnace BTU

You need to remember, that “BTU/h” is sometimes abbreviated to just “BTU”. The modern unit of power for heating and cooling systems is the watt. 1000 BTU/h is approximately 293.1 W.

Some manufacturers have started to calculate furnace size in MBHs rather than BTUs. One MBH is 1000 BTU per hour, then you’re still using the same unit: 60 MBH is equal to 60000 BTU.

The general BTU per square foot heating rule of thumb varies from 30 BTU per square foot to 60 BTU per square foot based on your climate zone. That is a significant variation, with one furnace being twice as powerful as the other, so the size factors are explained here to help you in how to size a new furnace for a house.

A bigger furnace, such as one with an output of 120000 BTU per hour, will provide enough heat for a larger space. A smaller furnace will have a smaller BTU capacity, such as 40000 BTU per hour, and would be suitable for only a smaller pace.

Calculating BTU requirements for a house

Let’s start with this useful map. The climate becomes progressively colder from zone 1 to 3.

Find your location on the map. If you’re on or close the border between two zones, choose the higher number, the cooler zone.

Canada climate zones

Take the square footage of your home. If you don’t know it, you can look up the blueprint of the house, or measure rectangles within your home. Multiply the width by length for each rectangle and add them together.

It is not quite accurate, but nevertheless very useful for our purposes. While you shouldn’t use this calculation to make a final decision about furnace size, you can use it to get an idea of the size range to look at when you buy a new furnace. You can get a basic estimate using the square footage of your house.

The general rule of thumb is that you need between 30 and 60 BTU per square foot. Depending on your climate zone, you can determine how many BTU per square foot you need.

As you live in Newmarket, Ontario (Zone 2), in a home which is 2000 square feet. The chart would tell that you probably need a 90000 BTU furnace.

This value is only a rough approximation to demonstrate how these previously mentioned factors can affect the furnace size you need to buy, how many BTUs needed to heat a house. There are several additional factors that can affect the final furnace sizing calculation.

We need to inform people living in Stouffville on how to prepare for and avoid house fires. Heating systems are one of the leading causes of house fires, second only to kitchen equipment, according to data, therefore it is essential to be aware of furnace safety. Fortunately, there are some simple precautions you can take to minimize the possibility of a fire and keep your house and family safe and prepared in case of emergencies.

Furnace Fire Causes

Furnaces may get very hot, especially if they are used constantly during the wintertime. Because of the heat, you should keep the area surrounding your furnace free of clutter. The majority of Stouffville fire deaths are the consequence of flammable objects being left close to a heat source, generally the gas furnace. To reduce the risk of fire, you should leave at least three feet of space around your furnace free.

You need to look for discoloration or heat on the walls surrounding the furnace. If you discover any of these indications, contact Air Tech Toronto to have a professional heating specialist inspect your gas furnace.

Carbon Monoxide Awareness in Stouffville

As a byproduct of burning fuel for heating, your gas furnace may emit potentially hazardous gases. Some of these gases, such as carbon monoxide, are odourless, making them extremely dangerous. When typical fuel-burning appliances and equipment which burns natural gas, oil, wood, propane, and kerosene do not get enough oxygen to burn, this odourless gas is generated as a byproduct of insufficient combustion. Furnaces, though, are intended to safely exhaust harmful gases outdoors. To minimize carbon monoxide buildup in the home, make sure that your vents are clean of any clogs or dirt.

Carbon Monoxide, known by its chemical fourmula of CO, is a toxic gas that cannot be seen, smelled, or tasted. CO is also known as the “silent killer.”

Carbon monoxide may accumulate in the house, particularly in enclosed areas, and this can have devastating consequences on humans and all living creatures.

CO has warning signs by how it affects humans. CO poisoning causes flu-like symptoms, such as:

  • headache
  • nausea
  • dizziness
  • fatigue
  • burning eyes
  • confusion
  • disorientation
  • drowsiness

CO poisoning affects your body’s ability to absorb oxygen. It can cause brain damage and death in extreme situations. The elderly, children, and those suffering from heart or respiratory problems may experience the affects sooner than the others. Even low quantities of CO gas might be extremely dangerous.

The best solution to protect yourself and your family in Stouffville against carbon monoxide poisoning is to eradicate it at the source. When it comes to CO safety, here is a checklist to take into account.

  • Have fuel-burning appliances installed by a professional Air Tech Toronto technician with over 35 years of experience.
  • Have all your fuel-burning appliances and vents are inspected annually.
  • Keep chimneys clear of small animals, leaves, and other debris to ensure proper ventilation.
  • Ensure your furnace is inspected for adequate ventilation.
  • Install a working carbon monoxide alarm near all sleeping areas in your home.
  • Remember to test your CO alarms once a month by pushing the test button on the unit.

Small Animals Can Cause a Furnace Fire

As leaves and tiny animals might sneak into your vents, it’s a good idea to make it a routine practice to check them frequently. If you have a cat, you may have seen it resting on the heating vent that delivers air to your ducted furnace. It may not be cold enough in the home or outside yet, but cats enjoy resting on furnace vents. Cats, like any other animal, are always looking for ways to feel relaxed. You may believe that your cat is intelligent enough to avoid every risk in your home on their own, but it may or may not recognize real danger. There are a number of HVAC hazards in your basement, including your gas furnace. Sitting near or on the furnace should not be encouraged.

We need to remind Richmond Hill residents how we can prepare for and prevent home fires. Since statistics show that heating systems are one of the main causes of home fires, second only to cooking equipment, it is important to be aware of furnace safety. Fortunately, there are some basic tips that can help to reduce the risk of fire and keep your home and family safe and prepared for emergencies.

Furnace Fire Causes

Furnaces can become hot, especially when they are in constant use during winter. This heat means that you should keep the area around your furnace clear. Most of fire deaths in Richond Hill are the result of combustible materials being left near a heat source, usually a furnace. Ideally, there should be at least a three foot area of space around your furnace to reduce the risk of fire.

You should also check the walls near the furnace to check for discoloration or heat. If you notice any of these signs in the vicinity, call a professional heating expert from Air Tech Toronto to check for gas furnace dangers.

Carbon Monoxide Awareness in Richmond Hill

As a side effect of burning fuel for heat, your furnace will produce potentially dangerous fumes. Some of these fumes, including carbon monoxide can be odorless, which makes them especially dangerous. This odourless gas is produced as a byproduct of combustion when common fuel-burning appliances and equipment that use natural gas, oil, wood, propane and kerosene, don’t get enough air to burn up completely. Fortunately, furnaces are designed to safely vent these fumes outside. Therefore, to avoid carbon monoxide build up in house, it is important to ensure that your vents are clear of any obstructions or debris.

Carbon Monoxide, also known as CO, is a poisonous gas that you can’t see, smell or taste. CO is often referred to as the “silent killer”.

Carbon monoxide at home can build up, especially in a confined room or space – and this can lead to toxic effects on humans and pets.

CO has warning signs by how it affects humans. CO poisoning causes flu-like symptoms, including:

  • headache
  • nausea
  • dizziness
  • fatigue
  • burning eyes
  • confusion
  • disorientation
  • drowsiness

CO poisoning makes it difficult for your body to absorb oxygen. In severe cases it can cause brain damage and death. The elderly, children and people with heart or respiratory issues may feel the effects sooner than others. Even small amounts of CO gas can be dangerous.

The best way to ensure that you and your family in Richmond Hill are not exposed to carbon monoxide is to eliminate this poisonous gas at the source. Here is a list to follow when it comes to CO safety.

  • Have fuel-burning appliances installed by a professional Air Tech Toronto technician with over 35 years of experience.
  • Have all your fuel-burning appliances and vents are inspected annually.
  • Keep chimneys clear of small animals, leaves, and other debris to ensure proper ventilation.
  • Ensure your furnace is inspected for adequate ventilation.
  • Install a working carbon monoxide alarm near all sleeping areas in your home.
  • Remember to test your CO alarms once a month by pushing the test button on the unit.

Small Animals Can Cause a Furnace Fire

Leaves and small animals can get into your vents, so it is a good idea to establish a routine of checking your vents are clear. If you’re a cat owner you may noticed your cat sitting on the heating vent that distributes air for your forced air furnace. It might not even be that cold in the house or outside yet, but cats love sitting on furnace registers. Cats like any other animal are constantly searching for comfort. You might think that your cat is smart enough to avoid all danger in your home on their own, but it may or may not understand where danger lies. In your basement there are a number of HVAC dangers including your furnace. Sitting near or on the furnace shouldn’t be something you encourage. There is always chance they get too close to the pilot light or brush up against a hot tube or duct. Cat and small animals pose a furnace fire hazard.

My name is Susan and I recently had to replace the furnace in my home because it was old, noisy and inefficient. I’m a relatively new homeowner (moving into my first home earlier this year), so naturally, I’m not too familiar with Toronto home heating options. Do I go with a new furnace or boiler or maybe a combi-boiler – whatever that is. Luckily, someone told me about Air Tech Toronto and this is how my experience learning about Toronto Home Heating Options went.

My Toronto Home Heating Options Weren’t So Confusing

I called Air Tech Toronto as soon as I started experiencing issues with my heating system. This was probably late in the winter months or maybe even early spring, so I wasn’t in desperate need of heat on a daily basis. When I told them about how the heat wasn’t really coming in steady, they were able to send out someone to assess the situation right away.

Now, I already knew ahead of time that my heating would need to be replaced sooner than later when I moved in – courtesy of my realtor. Apparently the unit was pushing 20 years old and even though it was running smooth, furnaces don’t normally last much longer than that. Sure enough, I was right.

Once Novel Care arrived, we had a much more detailed discussion about my furnace as well as how much a novice I am when it comes to being a homeowner. My technician, Dave, was very sympathetic to my situation and started to lay out my Toronto home heating options going forward.

To keep things simple here, it was really only 2 options that I needed. I have a bigger home that was left to me by my uncle, so combi boilers and ductless units didn’t make much sense to use. They’re better for smaller space living – like condos. That left me with either a boiler or a new furnace. Since I already had the ductwork in place, Dave recommended a new furnace. Boilers are great Toronto home heating options too but in this specific case, a furnace made sense financially. No point in letting all that ductwork go to waste.

I’m very grateful for the team at Air Tech Toronto. I’m still learning more and more about the basic systems in my home, but having this team respond quickly to my call and walk me through my options was something I really appreciate. I’d recommend Air Tech Toronto any day.

Being a homeowner is Toronto and the GTA isn’t easy and requires you to question just about every repair bill, maintenance fee, and any other cost that will inevitably rear its head. In the end, it all comes down to balance. You don’t want to book everything all at once, and you also can’t ignore everything in hopes it will get better. That’s exactly why booking fall duct cleaning is a good idea.

September & October Are Perfect Months For Fall Duct Cleaning

Luckily, duct cleaning is one of those things that doesn’t need to be done more than once a year in your home. This cuts down on cost and lets you save your hard earned money. The reason why the early fall months are the best times to book one is that it’s just before winter.

As the temperature drops, chances are you will be spending more and more time indoors to stay warm. Combine that with spending more money than you’d like around the holidays and you might find yourself hibernating until spring. More time inside means you have to remember to consider the air quality in your home. Over the year, vents and ductwork pick up debris in the air. This can build up over time and actually increase the risk for respiratory issues or even allergies for those of you with pets. Simply put, the air in your home is stuck in a vicious circle when your ductwork isn’t cleaned – and being exposed to that isn’t good for you or those you live with. Luckily, Air Tech Toronto can help.

Toronto and the GTA can have some pretty extreme weather. It’s either unbearable in the summer with humidity or freezing cold in the winter, so it’s important to know what your options are when it comes to heating and cooling. See why heat pumps might just be your best bet.

Heating And Cooling 101 – What You Need To Know

Unless you work in the world of HVAC, it can be pretty confusing to know the differences between central air conditioning and ductless, or heat pumps and boilers.

First things first, heat pumps are 100% useful in both the summer and winter months. When it gets hot out, the system works to pull in air from outside, cools it, and distributes it indoors. When it gets cold out, you can set it to heat your home. This time, the unit will pull in colder air and condense it so you only feel warm air coming in.

Another thing you should know is that heat pumps are great for keeping energy costs lower each month. They were actually designed to only control the temperature of a given area of your home at a time. This makes heat pumps great for heating and cooling living rooms, bedrooms and other frequently used spaces of your home – but not all at once. You should always consider asking a professional for an assessment to see if heat pumps make sense for your home. If you have a smaller, well-insulated space, then they could be your best option.

My name is Alex and I recently just bought a condo in the east end of the city. The building itself is a bit older and everyone is responsible for his or her own air conditioning/furnace. Since my building is at least 15 years old, I knew there was a chance I’d have some trouble with my HVAC. And that’s exactly what happened. I made the mistake of calling someone my property manager recommended without checking up on them first. Now I’m still dealing with these guys for my central heating repair and winter is almost over!

Should’ve Gone With Air Tech Toronto For Central Heating Repair

After countless calls and emails with this HVAC company, it’s slowly starting to become clear that maybe they aren’t as professional as I’d originally hoped. Sure they came recommended by my property manager, but that’s only because they’ve had some experience with my building. It had nothing to do with how good they were. It was just a matter of convenience!

Naturally I did some digging into other HVAC companies who might be able to help with my central heating repair needs, and Air Tech Toronto was the first one to get back to me. They were nice enough to answer my questions and listen to my situation. Thanks to them I was able to actually get a qualified professional to take a look at my furnace within a few hours of my call.

They recommended I let the other company finish up since they were the official installers and it wouldn’t cost me anything, but I just wanted this to be done. I should’ve just called Air Tech Toronto from the start.

As a homeowner in Toronto and the GTA, you know that repairs and upgrades to your place don’t come cheap. That’s why it’s so important to do some research and know what your options are before investing in some central heating alternatives like heat pumps.

Heat Pumps Make A Great Central Heating Alternative

For those of you who may not know about heat pumps, they are a ductless option. A heat pump pulls in air from outside, condenses it, and pushes it indoors through a single unit.

Since they don’t distribute warm air throughout the entire home, heat pumps are quite different than central heating. They don’t require vents or necessary ductwork associated with central heating, making them a very efficient option for heating specific areas of your home. Most people will have one unit per floor that will either be in a bedroom or living room. Having these smaller units relies on you only wanting to warm the most heavily used areas of your home. The idea is that by heating only the rooms you use most, you won’t be wasting energy heating up your entire living space. This keeps monthly energy bills lower than if you had central heating in place.

Naturally, if you already have the ductwork in place and are familiar with central heating, installing heat pumps may not be for you. Yes, they are cheaper than replacing your furnace, but it really depends on the size of your home, and which areas you’d like to keep warmest in the winter months. Often times, furnaces can last for up to 20 years if properly maintained, so if yours isn’t broken, swapping it out for a heat pump instead may not be the best use of your money.
