Your Home’s HVAC System and your Energy bill


In all modern residences, heating, ventilating, and air-conditioning are incorporated into a single system for utmost convenience and efficiency.  An HVAC system cools and heats the air to make the home comfortable and also ensures the quality of the air by allowing in some fresh air.  The latter is also important especially in small spaces or areas of the home where odor is retained.

HVAC systems also account for the largest use of home energy with almost 2/3 of energy use spent on heating the home and another 15% or more spent on heating water.

Since heating the home uses so much energy, it accounts for much of what you pay for your energy bill monthly.  Thus, it is important to have devices that are energy-efficient and that your home’s insulation is also top-notch.

By maintaining a good working HVAC system and proper insulation in your home, you can keep your energy consumption as reasonable as possible and save money.

Improve the energy-efficiency of your home with high-quality furnaces, air conditioners, and heat pumps to minimize energy costs. Combine thermal insulation and setting thermostats properly to reduce your monthly energy bills.

You should also check out the Chauffez Vert program in Montreal for the replacement of water heaters and heating systems. You can get a rebate of up to $1,275 (heating system) or $250 (water heater) for single-family residences subject to eligibility.

Cost of HVAC systems based on type of system


The price of your central air conditioning system or heating system is based on the type of system you choose. A combined central air and furnace will cost differently than a boiler and ductless air system.

Below you will find the average cost of HVAC systems based on type to help you choose the right one that meets your needs and budget.

Central Air-conditioning

Central air-conditioning is a very popular type of cooling system used in most modern homes. It has a big compressor with multiple ducts directed into each area of the house so that the whole home is cooled by only 1 system.

To install a central air-conditioning system, you may need to spend from $4,000 to $7,500. The cost of the installation may reach $5,000 but it could change based on factors such as model of the unit you choose. If you have a big home, the installation cost could be higher. The larger the unit you require, the more expensive the cost will be.

Ductless System

A ductless system or split system is comprised of small control units that service one area at a time. They can provide heating and cooling and operate without ducts. A ductless system can cost anywhere from $2,500 to $4,000, without installation. Simpler to install, the cost of installation is lower compared to a centralized system.

You must understand that this is only the price for one part of the residence. If you need to heat and cool multiple rooms. You will require multiple heads and more than 1 compressor. For a large home, the overall cost could be from $8,000 or more.


Similar to centralized air-conditioning systems, furnaces consist of ducts. It uses electricity or gas and provides hot air which is distributed through the ducts to every room. It can be used to heat an entire home with just 1 system.

A furnace typically costs less than a central air-conditioning system. The average price is from $3,000 to $5,000.

If your home is more than 2,000 square feet, you can choose a high-end system. The larger the home, the more expensive the cost in terms of system and installation.

Boiler systems

A boiler is another option for heating a home. While furnaces blow hot air in each room through ducts, a boiler pushes hot water into a radiator in every part of the house. Thus, a boiler can also heat an entire home using 1 system.

The average price of a boiler is around $8,000. It is typically more expensive than a furnace.

For a bigger home, the cost of a boiler system will be higher because you will need to have a bigger and more powerful system. You will also require more water pipes (except if your home already has them). A boiler system for a house with around 3,000 square feet could cost as much as $12,000 to $14,000.

Water heater

An HVAC system needs a hot water heater. Can you imagine taking a cold shower in the morning?

Hot water heaters are quite affordable. You can choose from tank water heaters that cost from $1,500 to $3,000 to tankless water heaters that cost from $3,500 to $5,000 to install.

Air Filtration

Air filtration is an essential part of any HVAC system. Filters are placed in ducts and ventilation systems to control airborne particles such as viruses, bacteria, animal dander, and pesticides that may be circulating in the air.

 It can be overwhelming to decide on the right type of HVAC system for your home. Fortunately, we have reliable and experienced partners who can offer you tailored solutions that can really improve your home’s energy efficiency and quality of life.

When to replace or repair your HVAC System


Many homeowners wonder whether to replace or repair an HVAC system with the goal of saving money.

Before you make a decision, you must weigh several factors. The most important thing to consider is the lifespan of your existing HVAC system. Based on information from EnergyStar, an air-conditioning unit can last from 15 to 20 years. A heat pump lasts, on average, for 16 years while a furnace can function well for 15 years.

HVAC systems also require periodic and good maintenance to preserve function and prolong lifespan. Repairs are necessary from time to time but notwithstanding these efforts, there will come a time when a replacement becomes inevitable.

An air-conditioning or heating system can be costly to replace with a brand-new one. If you continue to repair a unit that has outlived its life, it becomes more expensive to operate and may be more prudent to replace.

Repair vs. replacement of an air-conditioning system

Technology has made many changes to cooling systems to take into account environmental factors. If a cooling system stops working properly or does not provide the normal amount of cool air, if may be better to get a replacement.

Below you will find several things to consider when choosing between repairing or replacing your air-conditioning system.

  1. The unit’s age

It is important for you to consider the age of your cooling system. EnergyStar recommends that an air-conditioning system be replaced every 10 or 15 years.

If your air-conditioner is 9 years old, it isn’t a smart step to repair it unless it is a small fix. You should consult an HVAC company about your options.

  1. Frequency of repairs

If your unit is less than 15 years old but already requiring frequent repairs, it may be better to get a replacement.

Calling in a technician every now and then is a hassle and causes a lot of inconvenience and discomfort on your part. The expenses due to repairs can also become costly if continually done.

  1. Cost of the repairs

If you still can’t decide whether to repair or replace the unit and it is more than 10 years old, a brand-new unit may be a smarter investment. Consider the cost of repairing the unit a few more times versus the cost of a brand-new installation over the long-term.

Repair vs. replacement of a heating system

Every homeowner will experience a malfunctioning heating system. Is the heat suddenly not enough even when you hike up the thermostat? You may start to wonder if you should replace the unit or call in a technician to have it fixed.

Consider the following factors when making a repair or replace decision for your heating system.

  1. Safety

If your heating system has become a hazard, it is a no-brainer especially if the repair will cost money and the fix is only temporary.

Faulty wiring or stuck valves may be easy to fix. Bigger issues with a furnace can lead to carbon monoxide leaks that could pose serious risks to your health.

Consult a qualified professional and perform a cost-benefit analysis to make a wise decision.

  1. Age of the unit

How old is the unit? A furnace can last for 15 to 20 years. If your system is 20 years or older, it still does not mean it should be thrown out. The final consideration should be its current performance. If it is acting up and costing money to repair, it may be time to replace it as it may have outlived its usefulness.

  1. Performance

If your heating system is not working properly, it will not heat your home well enough. A good indicator of trouble with your heating system is if some of the areas in the home don’t reach the temperature you desire. Thus, some rooms would be warm while others not warm enough.

Compare the repair and replacement costs a new boiler or furnace. If you choose to repair, keep in mind that the same issue may crop up and require more repairs in the future. If the repairs cost 50% or more of a replacement, it may be better to take the plunge and go for a new unit.

4 Signs that your HVAC system needs a replacement


Apart from assessing the aforementioned factors when deciding to repair or replace an HVAC system, these additional signs may indicate that you need to replace your HVAC:

  1. More dust inside the home.

An HVAC system cools and heats the home and also provides adequate ventilation. If it is operating properly, an HVAC system improves the quality of the air by removing dust, dander, dirt, and debris.

An HVAC system also controls the humidity in the home. If you see more dust than usual or higher levels of humidity than before, an AC unit may not be working well and require a replacement.

  1. Unusual sounds

An air-conditioner and furnace in good condition operate quietly.  When they get older, unusual sounds may be heard, indicating that you should call a technician to check on it.

  1. Unusual Odor

If you smell odor that is unusual coming from your unit, it could be due to mold, melted wiring, or worse. A proper inspection by a qualified technician is necessary to see if the unit requires a replacement.

  1. Unexplained increase in energy bills

Are you seeing a spike in your energy bills? You should have similar bills each month unless your consumption changes. If you can’t explain the hike in your energy bill, it may be time to replace your HVAC system.
